Effectiveness and safety of filgotinib in rheumatoid arthritis: a real-life multicentre experience

OBJECTIVES

We investigated the effectiveness and safety of filgotinib in a real-life multicentre cohort of rheumatoid arthritis (RA) patients.

METHODS

RA patients were evaluated at baseline and after 12 and 24 weeks and were stratified based on previous treatments as biologic disease-modifying anti-rheumatic drug (bDMARD)-naive and bDMARD-insufficient responders (IR). Concomitant usage of methotrexate (MTX) and oral glucocorticoids (GC) was recorded. At each timepoint we recorded disease activity, laboratory parameters and adverse events.

RESULTS

126 patients were enrolled. 15.8% were bDMARD-naive (G0), while 84% were bDMARD-IR (G1). In G0, 45% of patients were in monotherapy (G2) and 55% were taken MTX (G3). In G1, 50% of patients were in monotherapy (G4) and 50% used MTX (G5).A significant reduction in all parameters at 12 weeks was observed; in the extension to 24 weeks the significant reduction was maintained for patient global assessment (PGA), examiner global assessment (EGA), visual analogue scale (VAS) pain, VAS fatigue, disease activity score (DAS)28- C-reactive protein (CRP) and CRP values. Filgotinib in monotherapy showed better outcomes in bDMARD-naive patients, with significant differences for patient reported outcomes (PROs) and DAS28-CRP. At 12 weeks, low disease activity (LDA) and remission were achieved in a percentage of 37.2 % and 10.7 % by simplified disease activity index (SDAI), 42.6 % and 5.7 % by clinical disease activity index (CDAI), 26.8 % and 25.2 % by DAS28-CRP, respectively. A significant decrease in steroid dose was evidenced in all patients. We observed a major adverse cardiovascular event in one patient and an increase in transaminase in another. No infections from Herpes Zoster were reported.

CONCLUSIONS

Our real-world data confirm the effectiveness and safety of filgotinib in the management of RA, especially in bDMARD-naive patients.

Long-Term Retention Rate of Tofacitinib in Rheumatoid Arthritis: An Italian Multicenter Retrospective Cohort Study

Background: Tofacitinib (TOFA) was the first Janus kinase inhibitor (JAKi) to be approved for the treatment of rheumatoid arthritis (RA). However, data on the retention rate of TOFA therapy are still far from definitive. Objective: The goal of this study is to add new real-world data on the TOFA retention rate in a cohort of RA patients followed for a long period of time. Methods: A multicenter retrospective study of RA subjects treated with TOFA as monotherapy or in combination with conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) was conducted in 23 Italian tertiary rheumatology centers. The study considered a treatment period of up to 48 months for all included patients. The TOFA retention rate was assessed with the Kaplan-Meier method. Hazard ratios (HRs) for TOFA discontinuation were obtained using Cox regression analysis. Results: We enrolled a total of 213 patients. Data analysis revealed that the TOFA retention rate was 86.5% (95% CI: 81.8-91.5%) at month 12, 78.8% (95% CI: 78.8-85.2%) at month 24, 63.8% (95% CI: 55.1-73.8%) at month 36, and 59.9% (95% CI: 55.1-73.8%) at month 48 after starting treatment. None of the factors analyzed, including the number of previous treatments received, disease activity or duration, presence of rheumatoid factor and/or anti-citrullinated protein antibody, and presence of comorbidities, were predictive of the TOFA retention rate. Safety data were comparable to those reported in the registration studies. Conclusions: TOFA demonstrated a long retention rate in RA in a real-world setting. This result, together with the safety data obtained, underscores that TOFA is a viable alternative for patients who have failed treatment with csDMARD and/or biologic DMARDs (bDMARDs). Further large, long-term observational studies are urgently needed to confirm these results.

Therapeutic Effects of Apremilast on Enthesitis and Dactylitis in Real Clinical Setting: An Italian Multicenter Study

INTRODUCTION

Enthesitis and dactylitis are difficult-to-treat features of psoriatic arthritis (PsA), leading to disability and affecting quality of life.

OBJECTIVE

The aim of this study is to evaluate enthesitis (using the Leed enthesitis index (LEI)) and dactylitis at 6 and 12 months in patients treated with apremilast.

METHODS

Patients affected by PsA from fifteen Italian rheumatological referral centers were screened. The inclusion criteria were: (a) enthesitis or dactylitisphenotype; (b) treatment with apremilast 30 mg bid. Clinical and treatment history, including PsA disease activity, were recorded. Mann-Whitney and chi-squared tests were used to assess the differences between independent groups, and Wilcoxon matched pairs signed-rank test assessed the differences between dependent samples. A p-value of <0.05 was considered statistically significant.

RESULTS

The Eph cohort consisted of 118 patients (median LEI 3); the Dph cohort included 96 patients with a median dactylitis of 1 (IQR 1-2). According to an intention to treat analysis, 25% and 34% of patients with enthesitis achieved remission (i.e., LEI = 0) in T1 and T2. The remission of dactylitis was 47% in T1 and 44% in T2. The per protocol analysis (patients observed for at least 12 months) showed that both dactylitis and LEI significantly improved in T1 (median LEI 1 (IQR 1-3)) and T2 (median LEI 0 (IQR 1-2)).

CONCLUSION

Eph and Dph PsA patients treated with apremilast experienced a significant improvement in enthesitis and dactylitis activity. After 1 year, enthesitis and dactylitis remission was achieved in more than one-third of patients.

Predictors of DAPSA Response in Psoriatic Arthritis Patients Treated with Apremilast in a Retrospective Observational Multi-Centric Study

BACKGROUND

To date, only a few real-world-setting studies evaluated apremilast effectiveness in psoriatic arthritis (PsA). The aims of this retrospective observational study are to report long-term Disease Activity Index for Psoriatic Arthritis (DAPSA) response of apremilast in PsA patients and to analyze the predictors of clinical response.

METHODS

All PsA consecutive patients treated with apremilast in fifteen Italian rheumatological referral centers were enrolled. Anamnestic data, treatment history, and PsA disease activity (DAPSA) at baseline, 6 months, and 12 months were recorded. The Mann-Whitney test and chi-squared tests assessed the differences between independent groups, whereas the Wilcoxon matched pairs signed-rank test assessed the differences between dependent samples. Logistic regressions verified if there were factors associated with achievement of DAPSA low disease activity or remission at 6 and 12 months.

RESULTS

DAPSA low disease activity or remission rates at 6 and 12 months were observed, respectively, in 42.7% (n = 125) and 54.9% (n = 161) patients. Baseline DAPSA was inversely associated with the odds of achieving low disease activity or remission at 6 months (odds ratio (OR) 0.841, 95% confidence interval (CI) 0.804-0.879; p < 0.01) and at 12 months (OR 0.911, 95% CI 0.883-0.939; p < 0.01).

CONCLUSIONS

Almost half of the PsA patients receiving apremilast achieved DAPSA low disease activity or remission at 6 and 12 months. The only factor associated with achievement of low disease activity or remission at both 6 and 12 months was baseline DAPSA.

POS1027 APREMILAST EFFICACY IN REAL WORLD SETTINGS: RESULTS FROM AN ITALIAN MULTI-CENTER OBSERVATIONAL STUDY

Background

Apremilast, an inhibitor of the phosphodiesterase 4, is indicated for Psoriatic Arthritis (PsA) treatment. The 3 years retention rate, an outcome indirectly related to efficacy, observed in clinical trials [1] is 55,5%. A single subsequent real world setting study [2] suggested a lower efficacy as it reported that the six months retention rate was about 57%.

Objectives

The main aim of this retrospective observational study is the assessment of apremilast 3 years retention rate in a real world PsA patients’ cohort. Moreover, the secondary objective is reporting the reasons of apremilast suspension and the most relevant factor related to treatment persistence.

Methods

In thirteen Italian rheumatological referral centers, all PsA consecutive patients who received apremilast were enrolled. Anamnestic data, treatment history and PsA disease activity (DAPSA) at baseline and after 6 and 12 months were recorded. The Kaplan-Meier curve and the Cox analysis computed the apremilast retention rate and treatment persistence-related risk factors. A p-value < 0.05 was considered statistically significant.

Results

The three-hundred-twenty-four enrolled patients (median age 60 [InterQuartile Range IQR 52-67] yrs; female prevalence 57,0%) median observation period was 17 [IQR 7-36] months (6848 patients-months). The apremilast retention rate at 6, 12 and 36 months was, respectively, 95%, 86% and 66% (Figure 1). The main discontinuation reasons were: primary inefficacy (40% of interruptions), secondary inefficacy (18%) and gastro-intestinal intolerance (17%%). The oligo-articular onset was the only factor associated to apremilast persistence (Hazard ratio 0.57 IQR 0.34-0.96). Sex, age, and sever comorbidities (cancer, chronic infections etc) were not related to treatment discontinuation. The basal DAPSA (24.1, IQR 18.5-32.0) decreased after 6 and 12 months (respectively 14.5, IQR 10.1-22.6 and 10.5, IQR 8,0-15.2). Remission or minimal disease activity (DAPSA < 15) was achieved after 12 months in 38.0% of patients.

Conclusion

Almost two third of PsA patients receiving apremilast were still in treatment after 3 years. The study’s data, confirmed its efficacy and safety profile. Apremilast appear a good treatment choice in patients with oligo articular PsA or burdened by severe comorbidities.

Cancer patients’ awareness about clinical research in the era of social media and “fake news”: Preliminary results from ELPIS Study

e24121

Background: Barriers for low recruitment in clinical trials have been classified based on three main sources: physician, patient, system. A primary role is played by a low patient awareness, which often leads to a lack of confidence in science and a substantial inability to estimate the benefits deriving from trial participation, aggravated by the spread of fake news. A prospective observational study was conducted to investigate the views of cancer patients on aspects of clinical research, their expectations, the level of comprehensibility of informed consent and the impact of the fake news phenomenon. Methods: From January 2018, after Ethics Committees approval, the ELPIS study was initiated in 9 Italian Medical Oncology Units. After signing the informed consent, patients were asked to complete a questionnaire, consisting of a set of multiple choice and Likert-score questions. Results: As of January 2021, 115 patients were enrolled, with a balanced sex distribution and a prevalence of subjects older than 55-years (79.8%). Regarding the previous knowledge about clinical research, the average score was 3.9 (range 1-5). The vast majority of respondents (91.3%) had already started experimental therapy and many of them constantly used internet (65.2%) and social networks (34.8%). More than half (53.9%) stated the interview with the physician was sufficient for a full understanding of informed consent. In case of doubt, the majority seeked support in the clinician (39.1%) while very few (1.7%) relied on the web. The average score attributed to doctor-patient relationship was equal to 8.89 (range 1-10). Respondents were quite confident in their ability to independently search for information on their disease, discriminate fake news and identify reliable sites (average score 3.26, 3.27, 3.09 respectively, over a range of 1-5). The scores related to the presumed ability to understand the results of a clinical study and to actively collaborate to produce research were high (average score 4.72 and 4.39 over a range of 1-5). Conclusions: Preliminary data from our research show a good level of patient awareness and a fine ability to understand information, discerning real from fake news. Continuing and implementing the training initiatives of the population in the health sector will certainly contribute to further improvement, hopefully obtaining an even greater involvement of patients in the early phases of research.

Patient associations and clinical oncology research: how much does a patient's voice really matter?

Background: New trends are emerging in clinical research, such as patient empowerment and an active role in influencing health and research ethics. Patients' involvement is considered pivotal by stakeholders and institutions because they can channel the voice of those they represent, empowering their starring role in the different research activities.Objectives: To obtain an overview of the real involvement of Italian patient associations in clinical research.Methods: In January 2019, the Working Group 'Clinical Research Coordinators' of the Italian Association of Medical Oncology spread an online questionnaire consisting of 16 questions on the active involvement of patient associations in clinical research.Results: The involvement in clinical research working groups, in the organization and implementation of specific activities and training initiatives is very limited (21.7% in both cases), as well as the active involvement in the conduct and/or definition of clinical trials (0.3%). Moreover, few associations (15.2%) have joined projects on patient involvement in clinical research in collaboration with other associations.Discussion: Although the current involvement of the associations may have been somewhat underestimated, there is no doubt that much more can be done in terms of training and identification of common objectives between patients and professionals.

Eribulin mesylate use as third-line therapy in patients with metastatic breast cancer (VESPRY): a prospective, multicentre, observational study

Background

In real-world practice, eribulin mesylate provides significant survival benefit, with a manageable safety profile in heavily pretreated patients with metastatic breast cancer (MBC).

Methods

In this prospective, open-label, multicentre, observational study we evaluated the effectiveness and tolerability of eribulin as third-line treatment in a homogeneous population. The primary endpoints were the safety profile and response in metastatic sites; secondary endpoints included the response in different subtypes, overall response rate (ORR), progression-free survival (PFS) and overall survival (OS).

Results

From 2013 to 2016, 118 women were treated in 21 Sicilian institutions; the median age was 58 years (range 29-79), with 69% of patients under 65. The median cycles of eribulin were 5.5 (range 1-26). The most common adverse event was neutropenia (9.3%, 3 cases of grade 3, 4 of grade 4); only 1 case of QT prolongation was reported. Eribulin was effective in controlling metastatic disease in all sites, and it achieved the highest ORR in brain (16%) and liver (14.9%). Median OS was 31.8 months (95% CI 27.9-34.4) and median PFS 5.5 months (95% CI 4.2-6.6). PFS was 5.2 months (95% CI 2.8-8.4) in patients with triple-negative subtype. Median PFS was longer in patients over 65 years (6.1 months, 95% CI 4.4-8.3). In patients who had visceral metastases PFS was 5.5 months (95% CI 95% 3.5-6.6) and OS 33.9 months (95% CI 29.8-40.8).

Conclusions

Eribulin as third-line treatment shows an acceptable safety profile and a substantial antitumour activity in the treatment of MBC, even in elderly patients and in those with visceral disease.

Phase I studies: a test bench for Italian clinical research

BACKGROUND

The Agenzia Italiana del Farmaco (AIFA) Determination 809/2015 sets all the requirements that clinical units and laboratories must meet in order to conduct phase I studies. Requirements include buildings, equipment, personnel, emergency management, as well as quality requirements defined in a set of standard operating procedures.

METHODS

In September 2018, the Italian Association of Medical Oncology working group, Clinical Research Coordinator, created an anonymous survey addressed to 51 medical directors of oncologic/hematologic clinical phase I units and all medical directors of generic and transversal units located in Italy and listed at the AIFA website.

RESULTS

Questionnaires from 24 institutions were collected, 9 previously inspected by competent authorities. All surveyed structures are certified to conduct profit studies and 1 is authorized to include healthy volunteers; 15 units implemented a Clinical Trial Quality Team in order to conduct nonprofit studies. At the time of data collection, a total of 398 proposals for phase I trials have been received, more than 50% coming from 3 institutes. A total of 144 phase I studies were active, with a median of 2.5 (Q1-Q3=0-6) studies for each center and asymmetric distribution of proposals.

CONCLUSION

The considerable number of proposals received from the interviewed centers indicates that Italy plays an important role in the international pharmaceutical scene, despite bureaucratic procedures that threaten exclusion from decision-making. The AIFA Determination will be an important opportunity to acquire a competitive working approach.

Multicenter study of the evaluation of eribulin (E) use in Sicily in metastatic breast cancer (MBC): A prospective registry (VESPRY trial)

e12565

Background: Eribulin Mesylate is a non taxane microtubule dynamics inhibitor, approved for heavily-pretreated MBC patients (pts). Methods: This is a multicenter, prospective, single arm study for E-treatment of third line in pretreated MBC pts, conducted in 14 oncology centers in Sicily. All pts had received two previous chemotherapy regimens for MBC. Pts received E at 1.23 mg/m2 on days 1,8 every 3 weeks until progression. Primary Endpoints: overall response rate (ORR) according to the site of metastases and safety. Secondary objectives: Progression-free survival (PFS) and ORR according to different subtypes. PFS curve was estimated using the Kaplan-Meier method. Multivariable logistic regression model were used to evaluate the associations of each variables with tumor response. ORR was assessed according to RECIST 1.1 and safety with CTCAE v4.0. Results: 122 pts were enrolled and received at least 1 dose of E. Median age was 58 (range 29-79). All received previously anthracycline and taxane based-therapies. Subtypes: Luminal A 69%, Luminal B 7%, HER2 enriched 4% and Triple Negative 20%. The most common metastatic sites were bone and liver; 67% had metastatic disease involving two or more organs. A median of 5 cycles of E (range 1-26) was administrated. 106/122 pts were evaluable for efficacy, all for safety. ORR was 48%. Exploratory subset analysis showed significantly higher ORR in the lung, liver and bone lesions compared to other site of metastases and in HER2 negative pts. Multivariable regression model showed that HER2 positive subtype was correlated with a poor response (odd ratio 6.7, 95% CI 1.2-36.5). The median PFS was 14.7 months (mos) (95% CI 7.2–25.7). Among pts with < 65 and ≥ 65 years, the median PFS was 14.7 and 25.7 mos, respectively. Most common toxicities: G2 diarrhea 1%, asthenia G1 4%, G2 neutropenia 6%, G1 neurotoxicity 5%, QT prolongation 1%, G4 mucositis in only one case. Conclusions: This study showed a significant improved of PFS with E in third line setting and a favorable safety profile compared with results reported in the pivotal trial. Our findings suggest that E has substantial antitumor activity when used early for the treatment for MBC with acceptable safety.
