The interplay of knowledge, motivation, and treatment response in medication adherence among patients with chronic myeloid leukemia treated with Imatinib. Leuk Lymphoma 2024:1-8. [PMID: 39291898 DOI: 10.1080/10428194.2024.2403671] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2024] [Revised: 09/03/2024] [Accepted: 09/07/2024] [Indexed: 09/19/2024]
Abstract
Chronic Myeloid Leukemia (CML) requires consistent medication adherence to Imatinib (IM) for optimal outcomes, however, adherence to oral chemotherapy is challenging. This observational study explores the relationship between patient knowledge, motivation, and adherence to IM therapy, and their collective impact on clinical outcomes. A prospective, observational study was conducted with 101 CML patients. The 6-Item Morisky Medication Adherence Scale (MMAS-6) was used to assess adherence, motivation, and knowledge levels. The study found that high motivation was significantly associated with lower BCR-ABL expression (p = 0.025). Patients with high knowledge and motivation had a 71% favorable response rate, compared to 0% in those with low knowledge and motivation (p = 0.01). As conclusion both patient motivation and knowledge are crucial for favorable treatment outcomes in CML. High levels of both significantly correlate with better clinical responses. Tailored interventions to enhance patient knowledge and motivation are essential.

Abstract
DISEASE OVERVIEW Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm with an annual incidence of two cases/100 000. It accounts for approximately 15% of newly diagnosed cases of leukemia in adults. DIAGNOSIS CML is characterized by a balanced genetic translocation, t(9;22) (q34;q11.2), involving a fusion of the Abelson murine leukemia (ABL1) gene from chromosome 9q34 with the breakpoint cluster region (BCR) gene on chromosome 22q11.2. This rearrangement is known as the Philadelphia chromosome. The molecular consequence of this translocation is the generation of a BCR::ABL1 fusion oncogene, which in turn translates into a BCR::ABL1 oncoprotein. FRONTLINE THERAPY Four tyrosine kinase inhibitors (TKIs), imatinib, dasatinib, bosutinib, and nilotinib, are approved by the United States Food and Drug Administration (FDA) for first-line treatment of newly diagnosed CML in the chronic phase (CML-CP). Clinical trials with second and third-generation TKIs in frontline CML-CP therapy reported significantly deeper and faster responses but had no impact on survival prolongation, likely because of their potent efficacy and the availability of effective TKIs salvage therapies for patients who have a cytogenetic relapse with frontline TKI therapy. All four TKIs are equivalent if the aim of therapy is to improve survival. In younger patients with high-risk disease and in whom the aim of therapy is to induce a treatment-free remission status, second-generation TKIs may be favored. SALVAGE THERAPY For CML post-failure on frontline therapy, second-line options include second and third-generation TKIs. Although potent and selective, these TKIs exhibit unique pharmacological profiles and response patterns relative to different patient and disease characteristics, such as patients' comorbidities and financial status, disease stage, and BCR::ABL1 mutational status. Patients who develop the T315I "gatekeeper" mutation display resistance to all currently available TKIs except ponatinib, asciminib, and olverembatinib. Allogeneic stem cell transplantation remains an important therapeutic option for patients with CML-CP and failure (due to resistance) of at least two TKIs and for all patients in advanced-phase disease. Older patients who have a cytogenetic relapse post-failure on all TKIs can maintain long-term survival if they continue a daily most effective/least toxic TKI, with or without the addition of non-TKI anti-CML agents (hydroxyurea, omacetaxine, azacitidine, decitabine, cytarabine, and others).

Abstract
Tyrosine kinase inhibitors (TKIs) have demonstrated significant efficacy against various types of cancers through molecular targeting mechanisms. Over the past 22 years, more than 100 TKIs have been approved for the treatment of various types of cancer indicating the significant progress achieved in this research area. Despite having significant efficacy and ability to target multiple pathways, TKIs administration is associated with challenges. There are reported inconsistencies between observed food effect and labeling administration, challenges of concomitant administration with acid-reducing agents (ARA), pill burden and dosing frequency. In this context, the objective of present review is to visit administration challenges of TKIs and effective ways to tackle them. We have gathered data of 94 TKIs approved in between 2000 and 2022 with respect to food effect, ARA impact, administration schemes (food and PPI restrictions), number of pills per day and administration frequency. Further, trend analysis has been performed to identify inconsistencies in the labeling with respect to observed food effect, molecules exhibiting ARA impact, in order to identify solutions to remove these restrictions through novel formulation approaches. Additionally, opportunities to reduce number of pills per day and dosing frequency for better patient compliance were suggested using innovative formulation interventions. Finally, utility of physiologically based pharmacokinetic modeling (PBPK) for rationale formulation development was discussed with literature reported examples. Overall, this review can act as a ready-to-use-guide for the formulation, biopharmaceutics scientists and medical oncologists to identify opportunities for innovation for TKIs.

Maximizing the Value of Chronic Myeloid Leukemia Management Using Tyrosine Kinase Inhibitors in the USA: Potential Determinants and Consequences of Healthcare Resource Utilization and Costs, with Proposed Optimization Approaches. Clin Drug Investig 2024; 44:91-108. [PMID: 38182963 DOI: 10.1007/s40261-023-01329-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/12/2023] [Indexed: 01/07/2024]
Abstract
BACKGROUND AND OBJECTIVES The introduction and widespread use of effective and well-tolerated tyrosine kinase inhibitors for chronic myeloid leukemia have been associated with marked increments in life expectancy and disease prevalence. These changes have been accompanied by elevations in costs of tyrosine kinase inhibitors, which typically must be taken ad vitam after diagnosis and tend to be more expensive than medical therapies for many other hematologic malignancies. The aims of this review included evaluating the potential associations and consequences of healthcare resource utilization and costs of tyrosine kinase inhibitors and possible clinical management approaches to mitigate them. METHODS A PubMed search of English-language US study reports was conducted that covered the interval of 2001 (US approval of imatinib) through 17 April, 2023 augmented by manual reviews of published bibliographies from the referenced articles and searches of other databases: Google Scholar and Scopus. RESULTS On the basis of this analysis of chiefly real-world evidence (administrative claims database studies), healthcare resource utilization and costs can be considered indicators of ineffective chronic myeloid leukemia management, including potentially mutation-driven treatment resistance and costly tyrosine kinase inhibitor switches, non-adherence, and suboptimal tolerability, which may culminate in the progression of disease from the chronic to an accelerated or blast phase, with additional excess costs. Costs of tyrosine kinase inhibitors are also associated with reduced treatment adherence. At a willingness-to-pay threshold of $50,000-$200,000 per quality-adjusted life-year, tyrosine kinase inhibitors can be considered cost effective from a US payer perspective. Potential clinical approaches to mitigate costs include regular molecular monitoring with proactive assessments of BCR::ABL1 gene mutations to avoid costly treatment switches, as well as interventions to enhance treatment adherence and tyrosine kinase inhibitor tolerability. CONCLUSIONS Healthcare resource utilization and costs of chronic myeloid leukemia care may be considered barometers of ineffective management, including mutation-driven tyrosine kinase inhibitor resistance and switching as well as non-adherence and intolerance. Future prospective research is warranted to help determine whether costs can be reduced and other treatment outcomes optimized via more proactive and effective diagnostic interventions (i.e., regular molecular monitoring and proactive mutational testing) and treatment approaches. The strengths and limitations of this review include its emphasis on observational research, which, on one hand, offers a naturalistic "real-world" perspective on current chronic myeloid leukemia management, but, on the other hand, is associational in nature and cannot be used to determine causality and/or its direction.

Abstract
INTRODUCTION Adherence to imatinib in chronic myeloid leukemia (CML) patients is estimated to be as low as 70% despite its clinical benefit, and our understanding of the impact of nonadherence in this population is limited. This study presents a novel application of the Alternating Conditional Estimation (ACE) algorithm in newly diagnosed CML patients to map the full dose-response curve (DRC) and determine how the strength of this curve varies over time. METHODS We applied the ACE algorithm alongside a backward elimination procedure to detect the presence of time dependence and nonlinearity in the relationship between imatinib adherence and time-to-remission. An extended Cox model allowing for the flexible modeling of identified effects via unpenalized B-splines was subsequently fit and assessed. RESULTS The substantial improvement in model fit associated with the extended Cox approach suggests that traditional Cox proportional hazards model assumptions do not hold in this setting. Results indicate that the DRC for imatinib is non-linearly increasing, with an attenuated effect above a 74% adherence rate. The strength of this effect on remission varied over time and was strongest in the initial months of treatment, reaching a peak around 90 days post-initiation (log hazard ratio: 2.12, 95% confidence interval: 1.47 to 2.66). CONCLUSION Most patients that achieved remission did so by 4 months (120 days) with consistently high adherence, suggesting that this could be a critical time and duration for realizing treatment benefit and patient monitoring. Findings regarding the relationship between adherence and remission can additionally help guide the design of future studies.

Abstract
PURPOSE To ensure optimal care for patients with chronic myeloid leukemia (CML), adherence to tyrosine kinase inhibitors (TKIs) has emerged as a critical component. The objective of this study was to assess the impact of TKIs adherence on clinical outcomes in a cohort of Chinese CML patients who received treatment with TKIs. METHODS This retrospective study employed a cross-sectional design utilizing questionnaires to assess adherence to TKIs in a sample of 398 patients diagnosed with CML. Adherence was measured using the Morisky Medication Adherence Scale (MMAS-8), which dichotomizes patients into low, medium, and high adherence groups. RESULTS Of the patients included in this study, 34.2% were classified as highly adherent, with 43.2% and 22.6% of patients categorized as having medium and low adherence, respectively. Compared to the low-adherence group, patients in the medium- and high-adherence groups exhibited significantly higher rates of achieving major molecular response (MMR) and lower rates of switching TKIs. Moreover, patients who failed to adhere to TKIs treatment demonstrated significantly lower event-free survival and failure-free survival compared to those in the high-adherence group. Notably, regular molecular monitoring and utilization of the "CML Academy" mobile application were positively associated with increased TKI adherence. On the other hand, patients receiving third-generation or above first-line TKIs treatment displayed reduced adherence. CONCLUSION The findings suggest that high adherence to TKIs treatment confers clinical benefits to patients with CML. Accordingly, the implementation of effective guidance and intervention measures aimed at promoting adherence to TKIs therapy in real-world settings is imperative.

Abstract
Over the last 2 decades, the introduction of targeted therapies and the advances in the detection of BCR::ABL1 oncogene have dramatically improved comprehensive care for patients with Chronic myeloid leukemia (CML). The once deadly malignancy has now transformed into a chronic disease with an overall patient survival approaching that of the age-matched general population. While excellent prognoses have been reported among CML patients in high-income countries, it is unfortunately not the same for those living in low and middle-income (LMIC) countries such as Tanzania. This disparity is largely contributed by barriers associated with the provision of comprehensive care including early diagnosis, access to treatment, and regular monitoring of the disease. In this review, we will share our experiences and lessons learned in setting up a network of comprehensive care for patients with CML in Tanzania.

Abstract
Tyrosine kinase inhibitor (TKI) use is critical in the care of patients with chronic myeloid leukemia (CML). Quantitative polymerase chain reaction (qPCR) testing for BCR-ABL1 every 3 months during the first year of TKI treatment is recommended to assure achievement of milestone response goals. Real-world evidence for the patterns of qPCR monitoring and TKI adherence in the older patient population is lacking. Using the Surveillance, Epidemiology, and End Results-Medicare database, we identified 1192 patients aged ≥66 years (median age, 74 years) with newly diagnosed CML who were followed up for ≥13 months from TKI initiation. In total, 965 patients (81.0%) had ≥1 test, with 425 (35.7%) and 540 (45.3%) of the patients tested during 1, 2, and ≥3 quarters (optimal monitoring) of the first year from TKI initiation, respectively. In multivariable analysis, diagnosis in later years and influenza vaccination before diagnosis, a proxy for health care access, were associated with optimal qPCR monitoring. Use of low-income subsidy and residing in census tracts with the lowest socioeconomic status were associated with less optimal monitoring. Patients with optimal monitoring were 60% more likely to be TKI adherent (odds ratio, 1.60; 95% CI, 1.11-2.31; P = .01) and had improved 5-year survival (hazard ratio, 0.66; 95% CI, 0.49-0.90; P < .01) than those without such monitoring. In this large, real-world study of CML management patterns, many older patients had suboptimal molecular monitoring, which was associated with decreased TKI adherence and worse survival.

Abstract
BACKGROUND Specialty medication nonadherence results in poor clinical outcomes and increased costs. This study evaluated the impact of patient-tailored interventions on specialty medication adherence. METHODS A pragmatic, randomized controlled trial was conducted at a single-center health-system specialty pharmacy from May 2019 to August 2021. Participants included recently nonadherent patients prescribed self-administered specialty medications from multiple specialty clinics. Eligible patients were stratified by historical clinic rates of nonadherence and randomized 1:1 to usual care or intervention arms. Intervention patients received patient-tailored interventions and 8 months of follow-up. A Wilcoxon test was used to analyze the difference in 6-, 8-, and 12-month post-enrollment adherence, calculated using proportion of days covered, between the intervention and usual care arms. RESULTS Four hundred and thirty eight patients were randomized. Baseline characteristics were similar between groups: mostly women (68%), white (82%), with a median age of 54 years (interquartile range, 40, 64). The most common reasons for nonadherence in the intervention arm were memory (37%) and unreachability (28%). There was a significant difference in median proportion of days covered between patients in the usual care and intervention arms at 8-months (0.88 vs 0.94, P < .001), 6-months (0.90 vs 0.95, P = .003), and 12-months post-enrollment (0.87 vs 0.93, P < .001). CONCLUSIONS Patient-tailored interventions resulted in significant specialty medication adherence improvement compared with standard of care. Specialty pharmacies should consider targeting nonadherent patients for adherence interventions.

Abstract
Background. Many factors contribute to oral anti-cancer therapy adherence, including counselling and educational support. Objective. We systematically review the literature evaluating the effectiveness of interpersonal communication-, counselling- and education-based interventions on patient adherence to oral anticancer therapy. Methods. Using search terms pertaining to medication adherence, oral anticancer therapy, and communication, education, and counselling, we conducted a systematic search for full-text, original research articles prior to 3/13/20. Two reviewers independently reviewed each paper for inclusion and charted study information. Results. Twenty-four articles were included. All considered the use of oral anticancer therapy between two defined time points. Four studies also considered the length of time a patient persisted on therapy. Half (n = 12) of the studies reported a statistically significant relationship between the intervention and medication adherence, with no consistent pattern among intervention structure/content and effectiveness. Programmes offering in-person counselling and those targeting patients with chronic myeloid leukemia (CML), tended to report positive findings. Most studies faced substantial risk of bias, and only two reported using a behavioural theory to guide interventional content. Conclusions. Findings highlight the infancy of evidence base and need for rigorous and large-scale studies grounded in established behavioural theories to advance patient-targeted educational and counselling practices supporting adherence to oral anti-cancer therapy.

Abstract
Medication adherence is directly associated with health outcomes. Adherence has been reviewed extensively; however, most studies provide a narrow scope of the problem, covering a specific disease or treatment. This project's objective was to identify risk factors for non-adherence in the fields of rheumatology, oncology, and cardiology as well as potential interventions to improve adherence and their association with the risk factors. The project was developed in three phases and carried out by a Steering Committee made up of experts from the fields of rheumatology, oncology, cardiology, general medicine, and hospital and community pharmacy. In phase 1, a bibliographic review was performed, and the articles/reviews were classified according to the authors' level of confidence in the results and their clinical relevance. In phase 2, 20 risk factors for non-adherence were identified from these articles/reviews and agreed upon in Steering Committee meetings. In phase 3, potential interventions for improving adherence were also identified and agreed upon. The results obtained show that adherence is a dynamic concept that can change throughout the course of the disease, the treatments, and other factors. Educational interventions are the most studied ones and have the highest level of confidence in the authors' opinion. Information and education are essential to improve adherence in all patients.

Abstract
PURPOSE The relationship between out-of-pocket spending and cost-related medication nonadherence among older rural- and urban-dwelling cancer survivors is not well understood. METHODS This retrospective cohort study used the Surveillance, Epidemiology, and End Results Program, Medicare claims, and the Consumer Assessment of Healthcare Providers and Systems survey linked data resource linked data (2007-2015) to investigate the relationship between cancer survivors' cost responsibility in the year before and after report of delaying or not filling a prescription medication because of cost in the past 6 months (cost-related medication nonadherence). Secondary exposures and outcomes included Medicare spending and utilization. Generalized linear models assessed bidirectional relationships between cost-related medication nonadherence, spending, and utilization. Effects of residence were assessed via interaction terms. RESULTS Of 6,591 older cancer survivors, 13% reported cost-related medication nonadherence. Survivors were a median 8 years (interquartile range, 4.5-12.5 years) from their cancer diagnosis, 15% were dually Medicare/Medicaid-eligible, and prostate (40%) and breast (32%) cancer survivors were most prevalent. With every $500 USD increase in patient cost responsibility, risk of cost-related medication nonadherence increased by 3% (risk ratio, 1.03; 95% CI, 1.02 to 1.04). After report of cost-related medication nonadherence, patient cost responsibility was 22% higher (95% CI, 1.11 to 1.32) compared with those not reporting nonadherence, amounting to $523 USD (95% CI, $430 USD to $630 USD). Medicare spending and utilization were also higher before and after report of cost-related nonadherence versus none. For survivors residing in rural (18%) and urban (82%) areas, residence did not modify adherence or cost outcomes. CONCLUSION A bidirectional relationship exists between patient cost responsibility and cost-related medication nonadherence. Interventions reducing urban- and rural-dwelling survivor health care costs and cost-related adherence barriers are needed.

Abstract
Tyrosine kinase inhibitors (TKIs) have vastly improved long-term outcomes for patients with chronic myeloid leukemia (CML). After imatinib (a first-generation TKI), second- and third-generation TKIs were developed. With five TKIs (imatinib, dasatinib, bosutinib, nilotinib, and ponatinib) targeting BCR::ABL approved in most countries, and with the recent approval of asciminib in the USA, treatment decisions are complex and require assessment of patient-specific factors. Optimal treatment strategies for CML continue to evolve, with an increased focus on achieving deep molecular responses. Using clinically relevant case studies developed by the authors of this review, we discuss three major scenarios from the perspective of international experts. Firstly, this review explores patient-specific characteristics that affect decision-making between first- and second-generation TKIs upon initial diagnosis of CML, including patient comorbidities. Secondly, a thorough assessment of therapeutic options in the event of first-line treatment failure (as defined by National Comprehensive Cancer Network and European LeukemiaNet guidelines) is discussed along with real-world considerations for monitoring optimal responses to TKI therapy. Thirdly, this review illustrates the considerations and importance of achieving treatment-free remission as a treatment goal. Due to the timing of the writing, this review addresses global challenges commonly faced by hematologists treating patients with CML during the COVID-19 pandemic. Lastly, as new treatment approaches continue to be explored in CML, this review also discusses the advent of newer therapies such as asciminib. This article may be a useful reference for physicians treating patients with CML with second-generation TKIs and, as it is focused on the physicians' international and personal experiences, may give insight into alternative approaches not previously considered.

Abstract
BACKGROUND Since prices of imatinib (Gleevec) remain high, patients on oral chemotherapy are looking for alternative methods to access this life-saving medication. We assessed the accessibility of imatinib through online pharmacies and analyzed each website for medication safety, price, and marketing tactics. METHODS We searched the term "buy imatinib online" using 4 commonly used internet search engines (Google, Bing, Yahoo!, and DuckDuckGo) and screened web pages displayed in the first 10 pages. Websites were included if they were published in English, sold imatinib, were free to access, and offered shipping in the United States. Websites were classified using LegitScript's categorization as "certified," "unclassified," "unapproved," or "rogue." We analyzed information on websites' patient safety characteristics, marketing techniques, pricing, domain registration information, and IP addresses. RESULTS Of the 44 online pharmacies identified, only 3 (7%) were certified, and the remainder were classified as rogue (52%; n=23), unapproved (30%; n=13), or unclassified (11%; n=5). Thirteen online pharmacies (30%; 9 rogue, 4 unclassified) sold imatinib without a prescription. Nearly one-quarter (n=10) of online pharmacies selling imatinib did not include drug-related warnings on their websites, and nearly half (n=21) did not limit the purchasable quantity. More than three-quarters (n=34) of online pharmacies selling imatinib did not offer pharmacist consultations, even though nearly all websites extended offers to speak with sales associates (91%; n=40). Most online pharmacies selling imatinib claimed price discounts (95%; n=42), but fewer provided bulk discounts (23%; n=10) or coupons (34%; n=15). One-third of rogue pharmacies selling imatinib (n=7) claimed to be registered or accredited on their websites. CONCLUSIONS The lack of safety measures taken by illegitimate online pharmacies endangers patient safety because they allow patients to purchase imatinib without appropriate evaluation for response, drug interactions, and adverse effects. Healthcare providers need to be aware of this practice and should assure patient access to imatinib through safe and legitimate pharmacies.

Abstract
DISEASE OVERVIEW Chronic Myeloid Leukemia (CML) is a myeloproliferative neoplasm with an incidence of 1-2 cases per 100,000 adults. It accounts for approximately 15% of newly diagnosed cases of leukemia in adults DIAGNOSIS: CML is characterized by a balanced genetic translocation, t (9;22) (q34;q11.2), involving a fusion of the Abelson gene (ABL1) from chromosome 9q34 with the breakpoint cluster region (BCR) gene on chromosome 22q11.2. This rearrangement is known as the Philadelphia chromosome. The molecular consequence of this translocation is the generation of a BCR::ABL1 fusion oncogene, which in turn translates into a BCR::ABL1 oncoprotein. FRONTLINE THERAPY Four tyrosine kinase inhibitors (TKIs), imatinib, dasatinib, bosutinib, and nilotinib are approved by the United States Food and Drug Administration for first-line treatment of newly diagnosed CML in chronic phase (CML-CP). Clinical trials with second generation TKIs reported significantly deeper and faster responses but had no impact on survival prolongation, likely because of the availability of effective TKIs salvage therapies for patients who have a cytogenetic relapse with frontline TKI therapy. SALVAGE THERAPY For CML post failure on frontline therapy, second-line options include second and third generation TKIs. Although potent and selective, these TKIs exhibit unique pharmacological profiles and response patterns relative to different patient and disease characteristics, such as patients' comorbidities, disease stage, and BCR::ABL1 mutational status. Patients who develop the T315I "gatekeeper" mutation display resistance to all currently available TKIs except ponatinib, asciminib, and olverembatinib. Allogeneic stem cell transplantation remains an important therapeutic option for patients with CML-CP and failure (due to resistance) of at least 2 TKIs, and for all patients in advanced phase disease. Older patients who have a cytogenetic relapse post failure on all TKIs can maintain long-term survival if they continue a daily most effective/least toxic TKI, with or without the addition of non-TKI anti-CML agents (hydroxyurea, omacetaxine, azacitidine, decitabine, cytarabine, busulfan, others).

Abstract
BACKGROUND Despite the rapid approval of targeted therapies for metastatic renal cell carcinoma (mRCC) evidence on real world treatment patterns remains limited. This study evaluated patterns of first-line targeted therapy utilization and adherence in older adults, a population with a high burden of RCC. METHODS 2093 patients aged ≥66 years with a primary diagnosis of mRCC were identified from United States (US)-based cancer registry and administrative claims data (2007-2015). We included only patients with de novo disease. We assessed the initiation of first-line targeted therapy within four months of diagnosis and persistence and adherence to targeted therapy, using the proportion of days covered (PDC). Multivariable logistic regression yielded adjusted odds ratios (ORs) and 95% confidence intervals (CIs) to describe characteristics associated with targeted therapy versus no targeted therapy initiation and for high (≥80% PDC) versus low adherence. RESULTS 28.8% of patients received first-line targeted therapy within four months of diagnosis, with the proportion of patients receiving targeted therapy increasing over time. Older age (one-year increment OR:0.95 95%CI 0.93, 0.97), high comorbidity burden (OR:0.65 95%CI0.46, 0.93) and clear cell histology (OR:1.54 95%CI 1.19, 2.00) were associated with targeted therapy initiation. 48.2% of patients exhibited a high PDC to oral targeted therapy at 120 days, which was attenuated with inclusion of patients who died during the time period (34.2% PDC ≥80%). CONCLUSION Increasing age, high comorbidity burden and non-clear cell histology were associated with decreased targeted therapy initiation among patients with de novo mRCC. Our findings suggest adherence to oral therapies was low; future research exploring the mechanisms and impact of low adherence in this older patient population is warranted.

Abstract
BACKGROUND Imatinib mesylate (IM) treatment adherence is a challenge, especially in an economic-social population neglected from developing countries. OBJECTIVE To create a new complementary audiovisual educational intervention model to improve IM treatment adherence of CML patients. METHODS Two adherence verification methods were applied before and after intervention: modified Morisky-Green test and molecular responses (BCR-ABL transcripts quantification). Adherence estimates were calculated using univariate and multivariate component analysis (MCA) for the socio-demographic and clinical characteristics of patients. RESULTS Modified Morisky-Green test results demonstrated a substantial increase of CML patient adherence from 23% (pre-film) to 65% (post-film). Greater improvement was obtained for patients presenting major molecular response (MMR) from 38% (pre-film) to 60% (post-film). Although slight gain for complete molecular response (CMR) from 23% (pre-film) to 26% (post-film) was achieved, it represents a total tumour regression. MCA identified that females <50 years-old, using less than two medications (no disease associated) and CMR condition were the most benefited with intervention. CONCLUSION Audiovisual educational intervention was an effective complementary pro-adherence model, activating patient memory and improving IM treatment adherence. Although this intervention shows effective, not all patients responded as expected, being necessary a combination of educational and clinical interventions to improve IM adherence.

Abstract
AIMS Adherence to therapy is a key factor in successful treatment. The aim of this systematic review is to assess the extent to which patients with better adherence to oral therapy have better clinical outcomes among cancer patients. METHODS All studies published in PubMed up to 20 October 2020, which considered the use of oral anticancer drugs for cancer patients and which correlated treatment adherence with a clinical outcome, were considered. RESULTS From the 42 studies considered in the systematic review, 14 were for oncological indications and 28 for haematological indications. There was considerable variance in calculation methods, outcomes considered, and in the definitions of adherence. However, it emerged that most studies reported a significant correlation between adherence to therapy and clinical outcome. CONCLUSION As adherence to therapy is a key factor in achieving a better clinical outcome, future studies with large samples, robust endpoints and the use of at least two methods of assessing adherence would be desirable in order to produce more robust evidence.

Aims: In light of the extended overall survival and improved quality of life provided by advanced prostate cancer (PC) oral therapies, this study aimed to describe treatment adherence to advanced PC oral therapies and evaluate associated patient characteristics and subsequent healthcare resource utilization (HRU). Patients & methods: Patients with advanced PC initiating apalutamide, enzalutamide or abiraterone acetate were identified from administrative data (October 1, 2014-September 30, 2019). Adherence and persistence at six months postinitiation were used to evaluate patient factors and HRU. Results: Aged ≥75 years, Black race, chemotherapy use and higher pharmacy paid amounts were associated with poor adherence/persistence, which translated to higher HRU. Conclusions: Strategies to increase adherence and persistence may improve patient outcomes and associated HRU.

Abstract
BACKGROUND/AIMS Adherence to tyrosine kinase inhibitors (TKIs) has become a critical aspect of care in chronic myeloid leukemia (CML). We aimed to examine the association of TKI adherence with overall survival (OS) outcomes in Korean patients diagnosed with CML and treated with TKIs using data from the National Health Information Database. METHODS This study included 2,870 CML patients diagnosed between 2005 and 2013. Drug adherence was evaluated according to the medication possession ratio (MPR) and classified as high adherence (i.e., MPR ≥ 0.95 [upper 50%]), moderate adherence (i.e., MPR ≥ 0.68 and < 0.95 [middle 25%]), and low adherence (i.e., MPR < 0.68 [lower 25%]). RESULTS The median MPR was 0.95 (range, 0 to 4.67). Male sex (p = 0.003), age < 70 years (p < 0.001), high income (≥ 30%, p < 0.001), and maintaining frontline TKI (< 0.001) were associated with better adherence. Adherence to dasatinib was the lowest (vs. imatinib or nilotinib, p < 0.001). Compared with high MPR patients, those with moderate MPR (hazard ratio [HR], 4.90; 95% confidence interval [CI], 3.87 to 6.19; p < 0.001) and low MPR (HR, 11.6; 95% CI, 9.35 to 14.42; p < 0.001) had poorer OS. CONCLUSION Adherence to TKI treatment is an important factor predicting survival outcomes in Korean CML patients. Male sex, age < 70 years, high income, and maintaining frontline TKI are associated with high adherence to TKI. Thus, those without these characteristics should be closely monitored for treatment adherence.

Abstract
The purpose of this pilot study was to assess Chronic Myeloid Leukemia (CML) patients’ adherence to, beliefs about, and barriers to oral anticancer agents (OAC) using brief self-report measures in community-based cancer clinics. Patients completed a structured interview including a health literacy assessment, a Brief Medication Questionnaire, two single-item self-report adherence questions, and the Medications Adherence Reasons Scale. Of the 86 participants, 88.4% were white; 55.8% male; mean age, 58.7 years; and 22.1% had limited health literacy. Nonadherence (missing at least one dose in the last week) was reported by 18.6% of participants and associated (p < 0.003) with less-than-excellent perceived ability to take CML medications (16.3%). Black participants reported more difficulty taking CML medications than white participants (28.6% vs. 8.3%, p = 0.053). Among all participants, 43.0% reported their CML medicine was ineffective and 24.4% that taking CML pills was somewhat to very hard. The most common reasons for missing a dose were simply missed it (24.4%) and side effects (18.6%). Most patients perceived their ability to take CML medication was good to excellent, yet nearly one in five reported missing at least one dose in the last week. Brief, no-cost self-report assessments to screen CML patients’ OAC adherence, barriers, and beliefs could facilitate counseling in busy community cancer clinics.

Abstract
PURPOSE To evaluate adherence (as measured by the medication possession ratio) to the first ever course of oral antineoplasic treatment in cancer patients before and after the implementation of a multidisciplinary consultation program (involving an oncologist, a pharmacist, and a nurse) and to investigate the program's impact on adverse events and drug-related problems. PATIENTS AND METHODS In a retrospective single-center study, we compared the medication possession ratio 2 months after treatment initiation in a control group (before multidisciplinary consultation program implementation) versus an interventional group (after multidisciplinary consultation program implementation). RESULTS Two months after oral antineoplasic treatment initiation, the mean ± standard deviation medication possession ratio did not differ significantly when comparing the interventional (multidisciplinary consultation program) group (n = 33; 0.99 ± 0.06) with the control group (n = 64; 0.94 ± 0.16) (p = 0.062). Patients in the multidisciplinary consultation program group had fewer adverse events in general (41, vs 109 in the control group; p = 0.048) and digestive adverse events in particular (6 vs 29, respectively; p = 0.007). A total of 53 and 40 drug-related problems were identified in the control and multidisciplinary consultation program groups, respectively (p = 0.074). CONCLUSIONS Implementation of an multidisciplinary consultation program was not associated with a significant difference in drug adherence (as assessed by the medication possession ratio), which was good before and after implementation. The multidisciplinary consultation program was associated with a lower incidence of adverse events.

Resistance to Tyrosine Kinase Inhibitors in Chronic Myeloid Leukemia-From Molecular Mechanisms to Clinical Relevance. Cancers (Basel) 2021; 13:cancers13194820.

Abstract
Simple Summary Chronic myeloid leukemia (CML) is a myeloproliferative neoplasia associated with a molecular alteration, the fusion gene BCR-ABL1, that encodes the tyrosine kinase oncoprotein BCR-ABL1. This led to the development of tyrosine kinase inhibitors (TKI), with Imatinib being the first TKI approved. Although the vast majority of CML patients respond to Imatinib, resistance to this targeted therapy contributes to therapeutic failure and relapse. Here we review the molecular mechanisms and other factors (e.g., patient adherence) involved in TKI resistance, the methodologies to access these mechanisms, and the possible therapeutic approaches to circumvent TKI resistance in CML. Abstract Resistance to targeted therapies is a complex and multifactorial process that culminates in the selection of a cancer clone with the ability to evade treatment. Chronic myeloid leukemia (CML) was the first malignancy recognized to be associated with a genetic alteration, the t(9;22)(q34;q11). This translocation originates the BCR-ABL1 fusion gene, encoding the cytoplasmic chimeric BCR-ABL1 protein that displays an abnormally high tyrosine kinase activity. Although the vast majority of patients with CML respond to Imatinib, a tyrosine kinase inhibitor (TKI), resistance might occur either de novo or during treatment. In CML, the TKI resistance mechanisms are usually subdivided into BCR-ABL1-dependent and independent mechanisms. Furthermore, patients’ compliance/adherence to therapy is critical to CML management. Techniques with enhanced sensitivity like NGS and dPCR, the use of artificial intelligence (AI) techniques, and the development of mathematical modeling and computational prediction methods could reveal the underlying mechanisms of drug resistance and facilitate the design of more effective treatment strategies for improving drug efficacy in CML patients. Here we review the molecular mechanisms and other factors involved in resistance to TKIs in CML and the new methodologies to access these mechanisms, and the therapeutic approaches to circumvent TKI resistance.

Abstract
BACKGROUND Lack of adherence to tyrosine kinase inhibitors (TKIs) is a significant problem resulting in incomplete cytogenetic response and increased mortality in patients with chronic myeloid leukemia (CML). Few studies have been conducted on interventions to improve adherence. The authors conducted a systematic review to explore studies that examined the impact of strategies to improve TKI adherence among individuals with CML. METHODS The first 2 authors completed a systematic literature review according to the guidelines in Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Studies (n=2633) conducted between 1980 and 2019 were identified through 3 databases and examined for inclusion/exclusion criteria. RESULTS Fourteen studies were identified which met the eligibility criteria. The studies only examined adherence to imatinib, dasatinib, or nilotinib. Ten of the 14 used large data sets (commercial health insurance plans or Surveillance Epidemiology and End Results [SEER] data) for analysis. The majority of the studies used a cohort design. Adherence was defined and measured in a variety of ways with most studies using 80% or higher as adequate adherence. Strategies not focused on health care costs used a multidisciplinary team approach. CONCLUSION Development of evidence to improve treatment adherence to TKIs for CML have relied on large data sets rather than prospective trials. Current studies lack patient focused interventions.

Abstract
The transition to oral therapies in patients with multiple myeloma (MM) offers potential benefits to patients; however, they must self-manage their medication and adherence plays an important role in patient care. It has been shown that patient satisfaction with their medication has a strong positive correlation with adherence in chronic diseases. The aim of this study was to estimate adherence rate of oral antimyeloma therapies and to identify risk factors for medication non-adherence. This observational, prospective, and multicentre survey based on a self-report questionnaire enrolled MM patients with at least 3 months of oral therapy. The 6-item Girerd scale and the medication possession ratio (MPR) were used for measuring medication adherence and the SATMED-Q® questionnaire was used for measuring satisfaction. An analysis of risk factors for non-adherence to oral therapy was performed using univariate analysis. A total of 101 patients participated in the survey, yielding a response rate of 87%. The prevalence of adherence to oral antimyeloma therapy was estimated at 51.5% using the Girerd questionnaire. According to the MPR, adherence was evaluated at 96% (i.e. MPR ≥ 0.80). Both methods combined, adherence was estimated at 50.5%. One risk factor for medication non-adherence was identified: Eastern Cooperative Oncology Group Performance Status > 2 (p = 0.007). One predictive factor for high medication adherence was identified: high satisfaction with treatment (p = 0.01). Identifying patients at higher risk for non-adherence allows clinical pharmacists to personalise therapeutic information and education and to improve the quality of healthcare overall.

Abstract
Patients with chronic myeloid leukemia (CML) can be treated with oral tyrosine kinase inhibitors (TKIs). Pharmacist-led oral chemotherapy programs (POCPs) can improve TKI adherence rates, but evaluation of patient satisfaction with such programs is rare. The purpose of this analysis was to compare the satisfaction of patients with CML taking TKIs enrolled in a POCP program with that of those not enrolled. Secondary objectives were to assess adherence rates, patient-reported value, early molecular response (EMR) rates, and major molecular response (MMR) rates. This study utilized an anonymous telephone survey of patients who had taken TKIs for at least 3 months. Molecular response was determined by chart review. Of 40 patients surveyed, 50% were enrolled in the POCP, and the POCP group had more African Americans than the non-POCP group. More patients in the POCP were satisfied with their care than in the non-POCP group (100% vs. 75%, p = .047). There were no differences in high patient-reported adherence (55% vs. 60%, p = 1.000), patient-reported value for integrated services (95% vs. 90%, p = 1.000), achievement of EMR (75% vs. 75%, p = 1.000), or MMR (85% vs. 85%, p = 1.000). Patients in the POCP received more structured clinical pharmacy services; however, both groups felt the clinical pharmacist played a major role in their care (85% vs. 90%, p = 1.000). Patients in the non-POCP group reported lower satisfaction than those enrolled resulting from fragmented care that was likely due to external specialty pharmacies. Irrespective of POCP enrollment, patients reported clinical pharmacists play a major role in their therapy and value integration of their specialty pharmacy and medical team.

Abstract
PURPOSE Suboptimal adherence to tyrosine kinase inhibitors (TKIs) is a widely recognized issue compromising the disease control and survival of patients with chronic myeloid leukemia (CML). A recently published review by Heiney et al reported inconclusive findings on the effects of a broad range of adherence enhancing interventions. The current systematic review aimed to identify studies that evaluated adherence-enhancing interventions implemented by healthcare professionals and determine their effect on CML patients' medication adherence and clinical outcomes. METHODS A systematic literature search was performed in 5 databases for articles published between 2002 and 2021. Studies that compared adherence enhancing interventions implemented by healthcare professionals with a comparison group were included. Relevant data on study characteristics were extracted. Medication adherence and clinical outcomes between intervention and control arms were compared. RESULTS Nine studies were included in two randomised controlled trials, four cohort studies, and three before-and-after comparison studies. All the included studies incorporated complex interventions, including intensive education or consultation with pharmacists, nurses or multidisciplinary team, in combination with one or more other strategies such as structured follow-up, written materials or video, psychotherapy, medication reminder or treatment diary, with the overall goal of monitoring and improving TKI adherence. Most (7 out of 9) studies demonstrated significantly better adherence to TKIs in the intervention group than the comparison group. The relative proportion of participants who adhered to TKIs ranged from 1.22 to 2.42. The improvement in the rate of TKI doses taken/received ranged from 1.5% to 7.1%. Only one study showed a significant association between intervention and clinical outcomes, with a 22.6% higher major molecular response rate and improvement in 6 out of 20 subscales of health-related quality-of-life. CONCLUSION Complex interventions delivered by healthcare professionals showed improvement in adherence to TKIs in CML patients. Further studies are required to clarify the cost-effectiveness of adherence-enhancing interventions.

Abstract
ABSTRACT Depression and anxiety, which may influence antiretroviral therapy (ART) medication adherence, are prevalent among persons living with HIV (PLWH) in China. This parallel two-arm clinical controlled trial aimed to examine the effects of a nurse-delivered cognitive behavioral intervention (CBI) on depression, anxiety, and ART medication adherence in Chinese PLWH. Using in-person and online recruitment, 140 PLWH ages 18 years and older who were undergoing ART and had a Patient Health Questionnaire-4 score of ≥2 were assigned to the 10-week-long CBI group or the routine follow-up group according to their preference. Outcomes were measured at baseline, postintervention, and 6-month follow-up. Results showed significant intervention effects on depression maintained until the 6-month follow-up. Although anxiety and ART medication adherence did not show robust effects between conditions, amelioration trends for these outcomes were also found. Our study demonstrated that the nurse-delivered CBI could help Chinese PLWH ameliorate depression.

Abstract
Clinical trials have demonstrated that some patients with chronic myeloid leukemia (CML) treated for several years with tyrosine kinase inhibitors (TKIs) who have maintained a molecular response can successfully discontinue treatment without relapsing. Treatment free remission (TFR) can be reached by approximately 50% of patients who discontinue. Despite having similar levels of deep molecular response and an identical duration of treatment, the factors that influence the successful discontinuation of CML patients remain to be determined. In this review we will explore the factors identified to date that can help predict whether a patient will successfully achieve TFR. We will also discuss the need for the identification of predictive biomarkers associated with a high probability of achieving TFR for the future personalized identification of patients who are suitable for the discontinuation of TKI treatment.

Abstract
With tyrosine kinase inhibitor (TKI) therapy, chronic myelogenous leukemia (CML) is now a chronic disease. CML patients treated with TKIs (n = 1200) were identified from the OptumLabs® Data Warehouse (de-identified claims and electronic health records) between 2000 and 2016 and compared with a non-cancer cohort (n = 7635). The 5-year cumulative incidence of all organ system outcomes was significantly greater for the TKI versus non-cancer group. In the first year, compared with imatinib, later generation TKIs were associated with primary infections (hazard ratios [HR] 1.43, 95% CI 1.02-2.00), circulatory events (HR 1.15, 95% CI 1.01-1.31), and skin issues (HR 1.43, 95% CI 1.13-1.80); musculoskeletal and nervous system/sensory issues were less common (HRs 0.83-0.84, p < 0.05). Increased risk of infections, cardiopulmonary and skin issues associated with later generation TKIs persisted in subsequent years. In this real-world population, TKI therapy was associated with a high burden of adverse events. Later generation TKIs may have greater toxicity than imatinib.

Abstract
BACKGROUND Chinese persons living with HIV (PLWH) suffer from prevalent mental health issues. We aimed to develop a tailored cognitive behavioral therapy (CBT), test its feasibility, acceptability, and preliminary effects (depression, anxiety, and medication adherence) for Chinese PLWH. METHODS Twenty PLWH were assigned randomly. Intervention participants learned skills in CBT and relaxation training in a tailored group-based weekly 10-session project. Each session lasted for two hours and was delivered by nurses and volunteers. Control participants only received laboratory tests and free antiretroviral therapy (ART) medication. Feasibility and acceptability were descriptively summarized. Depression, anxiety, and ART medication adherence data were collected at the baseline (T0), after the intervention (T1) and after 6 months of follow-up (T2). RESULTS The average CBT attendance rate for all sessions was 60%. No participants in the intervention group dropped out of the study. All participants in the intervention group agreed that they could benefit from the CBT. Participants in the intervention group showed a greater improvement in anxiety and self-reported ART medication adherence than those in the control group at T1. However, no preliminary intervention effect was found at T2. LIMITATIONS The small sample size leads to a lack of representativeness in the study sample. We excluded participants with severe comorbidities, which may lead to an underestimate of the intervention effect of CBT among Chinese PLWH. CONCLUSIONS CBT is feasible and acceptable, demonstrating promising preliminary effects on anxiety and ART medication adherence among Chinese PLWH. Additional research is needed to test the effectiveness of this approach.

Abstract
INTRODUCTION Although consistent use of tyrosine kinase inhibitors (TKIs) confers significant improvements in long-term survival for individuals with chronic myeloid leukemia (CML), only 70% of CML patients are adherent to TKIs. Understanding the factors that contribute to non-adherence and establishing dynamic adherence patterns in this population are essential aspects of targeted drug monitoring and intervention strategies. METHODS Newly diagnosed CML patients were identified in the MarketScan database and relevant covariate values extracted. Proportion of days covered (PDC) per 30-day interval was used to calculate adherence over a 12-month follow-up period. We conducted a latent profile analysis (LPA) on these PDC estimates to identify distinct, dynamic patterns of TKI adherence. Identified trajectories were grouped into four clinically relevant categories and predictors of membership in these categories were determined via multinomial logistic regression. RESULTS Four broad adherence categories were identified from the LPA: never adherent, initially non-adherent becoming adherent, initially adherent becoming non-adherent, and stable adherent. Results from the subsequent multinomial logistic regression indicated that younger age, female sex, greater monthly financial burden, fewer comorbidities, fewer concomitant medications, year of diagnosis, higher starting dose, TKI type, and a longer duration from diagnosis to treatment were significantly associated with membership in at least one of the three non-stable adherent groups. CONCLUSION Select sociodemographic and clinical characteristics were found to predict membership in clinically meaningful groups of longitudinal TKI adherence. These findings could have major implications for informing personalized monitoring and intervention strategies for individuals who are likely to be non-adherent.

Abstract
OBJECTIVE To examine the association among tyrosine kinase inhibitor (TKI) out-of-pocket costs, adherence, and health care costs and utilization in a large group of commercially insured patients with chronic myeloid leukemia (CML). MATERIALS AND METHODS Patients with CML aged 18 to 64 years were identified using IBM MarketScan Commercial Database between April 1, 2011 and December 31, 2014. Patients were required to be continuously enrolled 3 months before and 12 months after TKI (imatinib, dasatinib, or nilotinib) initiation. TKI adherence is estimated using the proportion of days covered (PDC), defined as the percentage of the PDC by the prescription fill during the 12-month study period (adherent patients have PDC ≥80%). Health care cost differences between adherent and nonadherent patients were estimated using generalized linear models. Health care utilization was compared using negative binomial regression models. All models were controlled for potential confounding factors. RESULTS The study sample consisted of 863 patients, where 355 (41.1%) patients were classified as adherent. Over the study period, nonadherent patients incurred US$10,974 more in medical costs (P<0.001), and US$1663 more in non-TKI pharmacy costs (P<0.01). Adherent patients incurred US$28,184 more in TKI pharmacy costs (P<0.001) that resulted in US$18,305 more in overall total health care costs (P<0.001). Adherent patients, however, were estimated to be less likely to have all-cause hospitalizations (incidence rate ratio, 0.32; P<0.001), or CML-specific hospitalizations (incidence rate ratio, 0.31; P<0.01). CONCLUSIONS Patients with CML with better adherence experienced fewer hospitalizations, resulting in medical service cost savings. These lower medical costs, however, were more than offset by higher TKI medication costs observed during the first year of TKI therapy.

Abstract
PURPOSE Chronic myeloid leukaemia (CML) patients on long-term tyrosine kinase inhibitor (TKI) therapy are susceptible to drug-related problems (DRPs). This study aimed to evaluate the acceptability and outcomes of pharmacist-led interventions on DRPs encountered by CML patients. METHODS This study included participants from the intervention arm of a randomised controlled trial which was conducted to evaluate the effects of pharmacist-led interventions on CML patients treated with TKIs. Participants were recruited and followed up in the haematology clinics of two hospitals in Malaysia from March 2017 to January 2019. A pharmacist identified DRPs and helped to resolve them. Patients were followed-up for six months, and their DRPs were assessed based on the Pharmaceutical Care Network Europe Classification for DRP v7.0. The identified DRPs, the pharmacist's interventions, and the acceptance and outcomes of the interventions were recorded. A Poisson multivariable regression model was used to analyse factors associated with the number of identified DRPs per participant. RESULTS A total of 198 DRPs were identified from 65 CML patients. The median number of DRPs per participants was 3 (interquartile range: 2, 4). Most participants (97%) had at least one DRP, which included adverse drug events (45.5%), treatment ineffectiveness (31.5%) and patients' treatment concerns or dissatisfaction (23%). The 228 causes of DRPs identified comprised the following: lack of disease or treatment information, or outcome monitoring (47.8%), inappropriate drug use processes (23.2%), inappropriate patient behaviour (19.9%), suboptimal drug selection (6.1%), suboptimal dose selection (2.6%) and logistic issues in dispensing (0.4%). The number of concomitant medications was significantly associated with the number of DRPs (adjusted Odds Ratio: 1.100; 95% CI: 1.005, 1.205; p = 0.040). Overall, 233 interventions were made. These included providing patient education on disease states or TKI-related side effects (75.1%) and recommending appropriate instructions for taking medications (7.7%). Of the 233 interventions, 94.4% were accepted and 83.7% were implemented by the prescriber or patient. A total of 154 DRPs (77.3%) were resolved. CONCLUSIONS The pharmacist-led interventions among CML patients managed to identify various DRPs, were well accepted by both TKI prescribers and patients, and had a high success rate of resolving the DRPs.

Abstract
Chronic disease management has been a significant burden in many countries. As most treatment options involve long-term pharmacotherapy, patient compliance has been a challenge, as patients have to remember taking medications on time at the prescribed dose for each disease state. Patients are often required to split the dosage unit, which may lead to under- or over-dose and dose-related adverse effects. However, 3D printing technologies have been used for fabricating personalized medications and multiple drugs in a single dose unit (polypills), which might greatly reduce treatment monitoring, dosing errors, and follow-ups with the health care providers. Extrusion-based 3D printing is the most used technology to fabricate polypills and to customize the dose, dosage form, and release kinetics, which might potentially reduce the risk of patient non-compliance. Although extrusion-based 3D printing has existed for some time, interest in its potential to fabricate dosage forms for treating chronic diseases is still in its infancy. This review focuses on the various extrusion-based 3D printing technologies such as fused deposition modeling, pressure-assisted microsyringe, and direct powder extrusion 3D printing in the preparation of customizable, multi-drug dosage forms for treating chronic diseases.

Abstract
BACKGROUND Medication adherence is a complex area of behaviour. Little is known about what influences chronic patients to take their medicines. This study has aimed to compare and contrast the health-related beliefs, experiences and types of behaviour typical among patients who have at least one chronic condition and are following a pharmacological treatment in accordance with their level of medication adherence. METHODS A questionnaire-based cross-sectional study, consisting of socio-demographic data, the 4-item Morisky-Green scale and 37 statements about health beliefs, perceptions and experiences, was conducted at different levels of healthcare (primary and tertiary settings). RESULTS A total of 577 questionnaires were analyzed. Respondents had a mean age of 64 and took an average of 4.6 drugs. Optimal adherence was reported by 58.6% of respondents. Bivariate analysis showed adherent subjects were older, took more medications, were in better spirits and had greater confidence and information regarding their treatment. Multivariate analysis found older age and the statements 'My doctor periodically reviews my treatment' and 'I am motivated to continue with the treatment' to be significantly related to medication adherence, while 'I make variations when taking medication depending on how I feel' was significant for medication non-adherence. CONCLUSION Medication non-adherence is common among chronic patients. Patient-centred approaches should be implemented in daily clinical practice as patient health beliefs, experiences and conduct influence medication-taking. Motivational interviewing might improve medication adherence in permitting emotional state managing and increasing educational skills, patient motivation and confidence between patients and healthcare providers.

Abstract
Background The list of oral and expensive chemotherapy agents has lengthened over the last few years and has created unique medication adherence concerns. In a real-life setting, patients often do not take their medications as prescribed. This pattern is associated with poor outcomes and increased health care costs. Objectives To estimate the adherence to oral anticancer chemotherapies and to determine the economic burden of unused medicines due to patients' death. Setting Alsace (France). Method This retrospective study was carried out by using ERASME, an Insurance Healthcare database. Main outcome measures Adherence was calculated using medication possession ratio and economic impact using prescription refill data. Results 10,734 patients were treated with oral anticancer medicines (cytotoxic agents, hormonal and targeted therapies). Averaged adherence of 0.86 was observed although it varied significantly between subclasses (cytotoxic agents: 0.69 ± 0.14, hormonal therapy: 0.91 ± 0.17 and targeted therapy: 0.79 ± 0.17). 1631 patients died during the study period. The expenses related to unused chemotherapies amounted to €152,175. Conclusions Our data showed that overall adherence to oral anticancer medicines was above the acceptable limit of adherence of 80% with a marked graduation in values between cytotoxic agents, hormonal and targeted therapies. These statistical significant differences in medication possession ratio could be related to the intrinsic toxicity of the three subclasses of molecules, their tolerance and adverse effects. To limit the cost associated with unused medicines, interventions such as dispensing expensive oral anticancer chemotherapies per unit over shorter periods and not only on monthly intervals could be implement.

Abstract
BACKGROUND This study aims to assess the effects of non-adherence to external beam radiation therapy in cancer patients receiving treatment with a curative. METHODS This retrospective cohort study collected health records data for all cancer patients treated with external beam radiotherapy with curative intent in 2016 in Catalonia, Spain. Adherence was defined as having received at least 90% of the total dose prescribed. A logistic regression model was used to assess factors related to non-adherence, and its association with one-year survival was evaluated using Cox regression. RESULTS The final sample included 8721 patients (mean age 63.6 years): breast cancer was the most common tumour site (38.1%), followed by prostate and colon/rectum. Treatment interruptions prolonged the total duration of therapy in 70.7% of the patients, and 1.0% were non-adherent. Non-adherence was associated with advanced age, female gender, and some localization of primary tumour (head and neck, urinary bladder, and haematological cancers). The risk of death in non-adherent patients was higher than in adherent patients (hazard ratio [HR] 1.63, 95% confidence interval 0.97-2.74), after adjusting for the potential confounding effect of age, gender, tumour site and comorbidity. CONCLUSION Non-adherence to radiotherapy, as measured by the received dose, is very low in our setting, and it may have an impact on one-year survival.

Abstract
BACKGROUND Oral tyrosine kinase inhibitors (TKIs) have been the standard of care for chronic myeloid leukemia (CML) since 2001. However, few studies have evaluated changes in the treatment landscape of CML over time. This study assessed the long-term treatment patterns of oral anticancer therapies among patients with CML. METHODS This retrospective cohort study included patients newly diagnosed with CML between January 1, 2000, and December 31, 2016, from 10 integrated healthcare systems. The proportion of patients treated with 5 FDA-approved oral TKI agents-bosutinib, dasatinib, imatinib, nilotinib, and ponatinib-in the 12 months after diagnosis were measured, overall and by year, between 2000 and 2017. We assessed the use of each oral agent through the fourth-line setting. Multivariable logistic regression estimated the odds of receiving any oral agent, adjusting for sociodemographic and clinical characteristics. RESULTS Among 853 patients with CML, 81% received an oral agent between 2000 and 2017. Use of non-oral therapies decreased from 100% in 2000 to 5% in 2005, coinciding with imatinib uptake from 65% in 2001 to 98% in 2005. Approximately 28% of patients switched to a second-line agent, 9% switched to a third-line agent, and 2% switched to a fourth-line agent. Adjusted analysis showed that age at diagnosis, year of diagnosis, and comorbidity burden were statistically significantly associated with odds of receiving an oral agent. CONCLUSIONS A dramatic shift was seen in CML treatments away from traditional, nonoral chemotherapy toward use of novel oral TKIs between 2000 and 2017. As the costs of oral anticancer agents reach new highs, studies assessing the long-term health and financial outcomes among patients with CML are warranted.

Abstract
Background Tyrosine kinase inhibitors have been demonstrated to improve the survival of patients with chronic myeloid leukaemia. However, medication adherence is vital for patients on chronic treatment. Objective The objective of the current study was to evaluate response to treatment, adherence by patients to tyrosine kinase inhibitors and factors associated with adherence and response. Setting A haematology clinic in a regional referral hospital in Malaysia. Method Patients aged ≥ 13 years who had been on imatinib or nilotinib for ≥ 12 months were included in this cross-sectional study. An optimal response was defined as the achievement of major molecular response at 12 months of treatment. Patient medication adherence was determined using the average medication possession ratio based on the dispensing records. The patients were considered adherent if the medication possession ratio was > 90%. Multiple logistic regression was performed to evaluate the factors associated with adherence. The association of adherence with molecular response was analysed by univariate logistic regression. Main outcome measure The primary outcome measures were the proportion of patients who achieved optimal response and the medication possession ratio. Results A total of 151 patients were screened, and 71 patients were included. Twenty-eight patients (39%) achieved major molecular response at 12 months of treatment. The median time to achieve this was 15.5 months (an interquartile range of 15). The mean medication possession ratio for imatinib and nilotinib was 0.94 (± 0.14) and 0.96 (± 0.10), respectively, but this difference was without statistical significance (t = - 0.517, p = 0.610). Nausea and vomiting (odds ratio [OR] of 0.25, 95% confidence interval [CI]: 0.07-0.83, p = 0.023) and disease phase at diagnosis (OR of 0.20, 95% CI 0.04-1.06, p = 0.059) were associated with patient adherence. An association was not found between patient adherence and molecular response (OR of 1.03, 95% CI 0.35-3.09, p = 0.956). Conclusion The patients in this study demonstrated a relatively deep molecular response and optimal adherence. Nevertheless, one fourth of them were noncompliant with imatinib. Therefore, active interventions are warranted to prevent treatment-associated adverse events and improve adherence.

Abstract
DISEASE OVERVIEW Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm with an incidence of 1-2 cases per 100 000 adults. It accounts for approximately 15% of newly diagnosed cases of leukemia in adults. DIAGNOSIS CML is characterized by a balanced genetic translocation, t(9;22)(q34;q11.2), involving a fusion of the Abelson gene (ABL1) from chromosome 9q34 with the breakpoint cluster region (BCR) gene on chromosome 22q11.2. This rearrangement is known as the Philadelphia chromosome. The molecular consequence of this translocation is the generation of a BCR-ABL1 fusion oncogene, which in turn translates into a BCR-ABL oncoprotein. FRONTLINE THERAPY Four tyrosine kinase inhibitors (TKIs), imatinib, nilotinib, dasatinib, and bosutinib are approved by the United States Food and Drug Administration for first-line treatment of newly diagnosed CML in chronic phase (CML-CP). Clinical trials with second generation TKIs reported significantly deeper and faster responses, but they had no impact on survival prolongation, likely because of the existence of highly effective salvage therapies for patients who have a cytogenetic relapse with frontline TKI. SALVAGE THERAPY For CML post failure on frontline therapy, second-line options include second and third generation TKIs. Although potent and selective, these exhibit unique pharmacological profiles and response patterns relative to different patient and disease characteristics, such as patients' comorbidities, disease stage, and BCR-ABL1 mutational status. Patients who develop the T315I "gatekeeper" mutation display resistance to all currently available TKIs except ponatinib. Allogeneic stem cell transplantation remains an important therapeutic option for patients with CML-CP who have failed at least 2 TKIs, and for all patients in advanced phase disease. Even among older patients who have a cytogenetic relapse post failure on all TKIs, they can maintain long-term survival if they continue on a daily most effective/less toxic TKI, with or without the addition of non-TKI anti-CML agents (hydroxyurea, omacetaxine, azacitidine, decitabine, cytarabine, busulfan, others).

Cancer Sci 2020; 111:2526-2535. [PMID: 32324296 PMCID: PMC7385357 DOI: 10.1111/cas.14430] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 04/09/2020] [Accepted: 04/17/2020] [Indexed: 01/05/2023] Open
Abstract
Treatment‐free remission (TFR), in which patients discontinue pharmacotherapy and remain in molecular remission, is an emerging treatment goal for patients with chronic myeloid leukemia (CML). Attainment of TFR requires an increased frequency of molecular monitoring, to ensure that patients maintain a deep molecular response. The objective of this analysis was to assess the economic impact of stopping nilotinib among Japanese TFR‐eligible patients. A Markov model evaluated the economic impact of TFR among the study population, TFR‐eligible CML patients diagnosed since 2012. The model compared patients who had discontinued tyrosine kinase inhibitor (TKI) treatment (ie, attempted TFR) with patients that continued TKI treatment. A 3‐y time horizon was modeled from a Japanese public payer perspective. Costs associated with drug treatment, hospital/physician visits, and molecular monitoring were considered. TFR‐eligible patients were calculated from Japanese CML incidence rates and efficacy was derived from nilotinib trials. Japanese co‐payment maximums were utilized to assess the patient perspective. An estimated 761 and 140 patients were eligible for first‐ and second‐line nilotinib, respectively, in 2019. Assuming that 100% of eligible patients complied, TFR was associated with cost savings of ¥7 625 174 640 (US$66 567 775) over 3 y. In scenarios with reduced willingness to attempt TFR, cost savings persisted. Achievement of TFR was estimated to markedly reduce out‐of‐pocket expenses for CML patients, regardless of the timing of relapse. Stopping nilotinib for TFR‐eligible patients in Japan may result in significant cost savings to both payers and patients. Monitoring costs contributed little to overall annual costs and decreased over time.

Abstract
PURPOSE To investigate the experiences of adults living with chronic myeloid leukaemia and treated with tyrosine kinase inhibitors, with particular reference to factors influencing adherence. METHODS A thematic synthesis of all published qualitative studies examining adults with chronic myeloid leukaemia, receiving tyrosine kinase inhibitors. Eligible publications were identified by searching five electronic databases using defined criteria. The synthesis involved complete coding of extracted data and inductive theme development. RESULTS Nine studies were included and three overarching themes defined. Overarching themes were: 1) Disease impacts whole life; 2) Disease management strategies; and 3) Valued aspects of care. Side-effects often required physical and psychological adaptation. Patients developed individual decision-making processes to promote adherence and manage side effects. Unintentional non-adherence occurred due to forgetfulness and system failures. Intentional omission also occurred, which together with side effects, was unlikely to be reported to healthcare professionals (HCPs). HCP reassurance about missed doses could reinforce non-adherence. Information needs varied over time and between individuals. Knowledge among patients about treatment was often lacking and could lead to misunderstandings. Patients valued psychological support from HCPs and suggested an individualised approach, facilitating discussion of symptoms, adherence and their perspectives about living with chronic myeloid leukaemia, would improve care. CONCLUSIONS Patients with chronic myeloid leukaemia experienced significant side-effects from treatment and changes to their psychological and physical well-being. They developed their own strategies to manage their disease and treatment. This should be recognised in interventions to improve education, support and the delivery of care that is compassionate and adequately resourced.

Abstract
BACKGROUND Adherence to treatment is correlated with treatment success in chronic myeloid leukemia (CML). CVS Specialty explored novel methods to improve adherence in this population to ensure optimal adherence and lower the risk of unsuccessful treatment. One novel program explored involved an interactive 2-way clinical messaging technology that coaches patients with adherence and knowledge about taking their treatment and managing their conditions. Clinical secure messaging is a 2-way messaging program distinct from the 1-way refill reminders and order status messages that patients were receiving if opted into the messaging program. OBJECTIVE To assess the effect on adherence of 2-way clinical messaging in a CML population treated with tyrosine kinase inhibitors (TKIs) compared with patients enrolled in 1-way refill reminders. METHODS A retrospective cohort study was conducted using prescription claims data. Patients new to TKI therapy and enrolled in at least 1-way messaging were identified and divided into control and study cohorts based on clinical messaging enrollment status. Participants were followed for 365 days after their first fill. Adherence outcomes were defined by medication possession ratio (MPR), length of therapy, first fill drop-off rate, and gap days between refills. Optimal adherence was defined as an MPR ≥ 85%. RESULTS Patients receiving clinical messaging had on average a 7.64% higher MPR score (MPR: 73.94% vs. 66.30%) compared with the control arm (P = 0.0063). This translates to 22% more patients being optimally adherent while exposed to clinical messaging (P = 0.022). Patients in the exposed group had a mean 32-day increase in average length of therapy compared with the control group (243 days vs. 275 days, P = 0.0043), potentially driving an increase in adherence. Additional drivers included a 5.4 percentage point reduction in first fill drop-off rates (4.66% vs. 10.04%, P = 0.0149). Persistency after 12 months was similar between the study arms (41%). CONCLUSIONS Two-way clinical messaging positively affected adherence outcomes in a CML population. This effect was in addition to 1-way refill reminders and order status messages. The nature of the clinical content encourages further investigation into this novel execution of adherence coaching and counseling through a digital platform.

Abstract
PURPOSE Although studies in other clinical areas have shown that patient-clinician communication can positively influence adherence to medications, little is known about how oncologists address medication counseling during routine office visits. We describe patient-oncologist office-based discussions of oral chemotherapy treatment. METHODS Transcripts of 24 patient-oncologist office visits were obtained from a national database. Patients were aged ≥ 19 years and prescribed capecitabine for colorectal cancer. We developed a structured coding worksheet using medication-counseling concepts previously identified as important to medication adherence and a grounded approach. Two coders reviewed transcripts for oncologists' provision of medication information, assessment of patients' adherence to medication, and the provision of self-management support for management of adverse effects. We assessed interrater reliability with Cohen κ statistics. We describe the counseling concepts present within patient-oncologist conversations and present illustrative quotes to describe how they were discussed. RESULTS Oncologists generally provided patients who had yet to initiate therapy comprehensive medication information; those in the midst of treatment received less information. Oncologists discussed patients' continued use of the medication (or discontinuation) among all patients who had initiated therapy (N = 18). How the patient was taking the medication (ie, therapy implementation) was less commonly discussed. Medication adverse effects were also discussed in all encounters. Self-management strategies were commonly provided, albeit mostly in response to a presenting symptom and not preemptively. Patients' use of concurrent medications, financial access to therapy, and assessments of logistical arrangements were discussed more sporadically. CONCLUSION Using audio recordings from a national sample of patient-oncologist office visits, we identified several potentially important opportunities to enhance medication counseling among patients prescribed capecitabine for the treatment of colorectal cancer.

Abstract
BACKGROUND Adherence to imatinib therapy has been significantly associated with disease progression and direct medical costs in gastrointestinal stromal tumor (GIST) patients. However, adherence to oral anticancer drugs is frequently hindered by the influence of various factors. The aim of this study was to evaluate the prevalence of imatinib adherence and its influencing factors among GIST patients in the adjuvant setting. METHODS Adherence of GIST patients (receiving imatinib for ≥1 month) was assessed using the 8-item Morisky Medication Adherence Scale (MMAS), with a score <8 indicating nonadherence. Quality of life and social support were evaluated by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ C30) and Social Support Rating Scale (SSRS). Factors associated with nonadherence were identified by multivariate logistic regression analysis. Imatinib plasma concentrations were determined and compared between adherent and nonadherent groups. RESULTS A total of 158 GIST patients were enrolled, 92 (58.2%) patients were considered nonadherent. Intentional nonadherence, especially feeling hassled by treatment plan (34.2% of patients), was common. In the multivariate logistic regression analysis, gender (OR 2.68, 95% CI 1.33-5.41; p = 0.0058), place of residence (OR 3.20, 95% CI 1.39-7.35; p = 0.0061), and global health status (OR 1.02, 95% CI 1.00-1.04; p = 0.0378) were significantly associated with nonadherence. Moreover, imatinib plasma concentrations in nonadherent patients were significantly lower than that in the good adherence group (p = 0.0338). CONCLUSIONS Poor adherence to imatinib is a notable problem in Chinese GIST patients in the adjuvant therapy setting. The predominant indicators of nonadherence in this study were gender (female), living in a rural area, and harboring a low global health status score. These indicators may aid clinicians in determining where increased efforts in promoting adherence may be beneficial.

Abstract
The treatment landscape of chronic myeloid leukemia (CML) was radically changed with the introduction of imatinib in 2001. With the emergence of treatment failure with imatinib, more specific and potent second- and third-generation tyrosine kinase inhibitors (TKIs) were developed. Currently, 6 TKIs and one protein synthesis inhibitor are available on the market for CML treatment. Despite the availability of these agents, it is not uncommon for some patients to experience treatment failure across several lines of therapy. Sequencing the available treatment options is a challenging task that becomes more complex after patients fail the more potent second- and third-generation TKIs. The ability to successfully salvage such patients is limited. In this paper, we will briefly review the mechanisms of treatment failure in chronic-phase CML (CP-CML) and focus on the complexity of managing patients who fail a second-generation TKI.

Abstract
PURPOSE Suboptimal adherence to tyrosine kinase inhibitors (TKIs) contributes to poor clinical outcomes in chronic myeloid leukemia (CML). This randomised controlled trial (RCT) aimed to evaluate the impact of a medication management service (MMS) on adherence to TKIs and clinical outcomes. METHODS A parallel RCT was conducted in two hospitals in Malaysia, where 129 CML patients were randomised to MMS or control (usual care) groups using a stratified 1:1 block randomisation method. The 6-month MMS included three face-to-face medication use reviews, CML and TKI-related education, two follow-up telephone conversations, a printed information booklet and two adherence aids. Medication adherence (primary outcome), molecular responses and health-related quality of life (HRQoL) scores were assessed at baseline, 6th and 12th month. Medication adherence and HRQoL were assessed using medication possession ratio and the European Organisation for Research and Treatment in Cancer questionnaire (EORTC_QLQ30_CML24) respectively. RESULTS The MMS group (n = 65) showed significantly higher adherence to TKIs than the control group (n = 64) at 6th month (81.5% vs 56.3%; p = 0.002), but not at 12th month (72.6% vs 60.3%; p = 0.147). In addition, a significantly higher proportion of participants in the MMS group achieved major molecular response at 6th month (58.5% vs 35.9%; p = 0.010), but not at 12th month (66.2% vs 51.6%; p = 0.092). Significant deep molecular response was also obtained at 12th month (24.6% vs 10.9%; p = 0.042). Six out of 20 subscales of EORTC-QLQ30-CML24 were significantly better in the MMS group. CONCLUSIONS The MMS improved CML patients' adherence to TKI as well as achieved better clinical outcomes. TRIAL REGISTRATION Clinicaltrial.gov (ID: NCT03090477).

Abstract
BACKGROUND For newly diagnosed chronic myeloid leukemia (CML) patients, early access to tyrosine kinase inhibitors (TKIs) is a consistent predictor of adherence and optimal response. The expense of targeted therapies, however, may result in high out-of-pocket costs for initiating therapy that could be a barrier to starting treatment. OBJECTIVE To examine the association between TKI out-of-pocket costs, initiation, and health care utilization and costs among patients who initiated TKI within 12 months after initial CML diagnosis. METHODS Individuals aged 18-64 years with an initial diagnosis of CML were identified in the IBM MarketScan Commercial Database between April 11, 2011, and December 31, 2014. The association between cost sharing and TKI initiation was evaluated using a multivariable logistic regression model applied to patients receiving therapy within a month of diagnosis and within 1-12 months after diagnosis. Health care utilization was compared using negative binomial regression models. Health care cost differences between the 2 patient groups were estimated using generalized linear models. All models were controlled for potential confounding factors. RESULTS The study sample consisted of 477 patients, with 397 (83.2%) patients initiating TKI within the first month of CML diagnosis and 80 (16.8%) after the first month. Out-of-pocket costs for the initial 30-day supply of TKI medications were not found to be a significant predictor of TKI initiation time. Patients initiating therapy within a month were less likely to have all-cause hospitalizations (IRR = 0.35; P = 0.02) or CML-specific hospitalizations (IRR = 0.27; P < 0.01). Over the 12-month follow-up period, they incurred $9,923 more in TKI pharmacy costs (P < 0.05), but patients initiating therapy after the first month of diagnosis incurred $7,582 more in medical costs, $218 more in non-TKI pharmacy costs, and $2,680 more in total health care costs (P > 0.05). CONCLUSIONS Patients with TKI initiation within the first month of diagnosis had higher TKI pharmacy costs that were partially offset by lower medical and non-TKI pharmacy costs, resulting in lower overall total health care costs. Findings suggest that earlier TKI initiation may reduce the risks of hospitalizations, which could result in potential medical cost savings in the first 12 months of treatment.
