Abstract
INTRODUCTION In patients with myelodysplastic syndromes (MDS), anemia is prevalent affecting 80%-85% of low-risk (LR-MDS) patients, with 40% eventually requiring red blood cell (RBC) transfusions. Except forlenalidomide, exclusively approved for those with deletion of chromosome 5q,erythropoiesis-stimulating agents (ESAs) are the primary treatment choice for low-risk patients. Those unresponsive to ESAs face limited alternatives, eventually necessitating long-term RBC transfusions, leading to secondary iron overload and adversely affecting quality of life (QoL). AREA COVERED Luspatercept is a pioneering erythroid maturation agent. It received approval by both the European Medicines Agency (EMA) and the Food and Drug Administration (FDA) for treating adults experiencing transfusion-dependent anemia associated with LR-MDS or β-thalassemia. Recently, the FDA approved luspatercept as first- line therapy in patients with very low- to intermediate-risk MDS who require RBC transfusions and have not previously received ESAs. This review summarizes the historical impact of luspatercept intreating LR-MDS unresponsive to ESAs and illustrates its potential benefit asfrontline therapy in MDS and its employment in patients with myelofibrosis-induced anemia. EXPERT OPINION Luspatercept has revolutionized the therapeutic paradigm of LR-MDS, for which there was a limited therapeutic arsenal, especially in the setting of patients who did not respond or fail after ESA treatment.

Abstract
WHAT IS THIS SUMMARY ABOUT? This is a summary of a research study called ARROW, which tested a medicine called pralsetinib in patients with non-small cell lung cancer (NSCLC), thyroid cancer, and other advanced solid tumours caused by a change in a gene called RET. For the purposes of this summary, only patients with NSCLC with a change in RET called fusion (RET fusion+) are highlighted. WHAT WERE THE RESULTS? In total, 281 patients with RET fusion+ NSCLC had taken part in this study across the USA, Europe, and Asia. Patients were asked to take four pills (adding up to 400 mg) of pralsetinib each day and were checked for any changes in their tumours, as well as for any side effects. After an average of 8 months of treatment with pralsetinib, 72% of previously untreated patients and 59% of patients who had previously received chemotherapy had considerable shrinkage of their tumours. Among 10 patients with tumours which had spread to the brain (all of whom had received previous treatments), 70% had their tumours shrink greatly in the brain after treatment with pralsetinib. On average, patients lived with little to no tumour growth for 16 months. In previously untreated patients, the most common severe side effects that were considered related to pralsetinib treatment were decreased white blood cells (neutrophils and lymphocytes), increased blood pressure, and an increase in a blood protein called creatine phosphokinase. In previously treated patients, the severe side effects were decreased white blood cells (neutrophils, lymphocytes, and leukocytes), increased blood pressure, and low levels of red blood cells. In both untreated and previously treated patients, the most common severe side effects that required hospital attention were lung inflammation/swelling causing shortness of breath (pneumonitis) and lung infection (pneumonia). WHAT DO THE RESULTS MEAN? Overall, the ARROW study showed that pralsetinib was effective in shrinking tumours in patients with RET fusion+ NSCLC regardless of previous treatment history. The recorded side effects were expected in patients receiving this type of medicine. Clinical Trial Registration: NCT03037385 (ARROW) (ClinicalTrials.gov).

Abstract
BACKGROUND To improve the early detection rate of multiple myeloma (MM), the M-protein screening system has been performed in the hospital population at Zhongshan Hospital Fudan University since 2014, with electrophoretic-based monoclonal immunoglobulin (M-protein) screening integrated into the blood biochemistry panel. This study updated 7-year follow-up findings of MM patients diagnosed by screening-driven and symptom-driven approaches. METHODS The retrospective study compared the characteristics and outcomes of patients diagnosed through two patterns by reviewing the plasma cell disease database from January 2014 to October 2021. The screening-driven group included patients diagnosed through the screening system during workups of unrelated medical conditions or routine checkups. In contrast, patients who visited or were referred to the hematological department due to myeloma-related end-organ damage were categorized into the symptom-driven group. RESULTS There were 3,110,218 serum protein electrophoresis (SPEP) tests performed during 7 years, with 1.95% (60,609) patients yielding positive SPEP results. Of 911 confirmed MM cases (excluding concurrent amyloidosis), 366 were assigned to the screening-driven group, while 545 were to the symptom-driven group. Compared to the symptom-driven group, the screening group had more IgG subtypes, earlier International Stage System stages, fewer disease-related symptoms, lower ECOG scores, less extramedullary disease, a lower percentage of bone marrow plasma cells, and a lower level of lactate dehydrogenase. Frontline response results of two groups were similar. Patients detected through screening had a significantly improved median progression-free survival (PFS) than the symptom-driven group (62.2 vs. 24.9 months, p < 0.001, HR: 2.12, 95% CIs: 1.69-2.65), with median follow-ups of 32.6 and 27.4 months. Furthermore, the median overall survival (OS) was significantly longer in patients of the screening group (not reached vs. 62.3 months, p < 0.001, HR: 2.49, 95% CIs: 1.81-3.41). After being adjusted for well-acknowledged myeloma prognostic factors, the screening-driven diagnostic pattern remained an independent prognostic factor indicating improved PFS and OS in MM patients. CONCLUSION Routine M-protein screening for MM in the hospital population results in an earlier diagnosis and better patient outcomes.

Abstract
BACKGROUND Imatinib, dasatinib, and nilotinib are tyrosine kinase inhibitors (TKIs) approved in Italy for frontline treatment of chronic-phase chronic myeloid leukemia (CP-CML). The choice of TKI is based on a combined evaluation of the patient's and the disease characteristics. The aim of this study was to analyze the use of frontline TKI therapy in an unselected cohort of Italian patients with CP-CML to correlate the choice with the patient's features. METHODS A total of 1967 patients with CP-CML diagnosed between 2012 and 2019 at 36 centers throughout Italy were retrospectively evaluated; 1089 patients (55.4%) received imatinib and 878 patients (44.6%) received a second-generation (2G) TKI. RESULTS Second-generation TKIs were chosen for most patients aged <45 years (69.2%), whereas imatinib was used in 76.7% of patients aged >65 years (p < .001). There was a predominant use of imatinib in intermediate/high European long-term survival risk patients (60.0%/66.0% vs. 49.7% in low-risk patients) and a limited use of 2G-TKIs in patients with comorbidities such as hypertension, diabetes, chronic obstructive pulmonary disease, previous neoplasms, ischemic heart disease, or stroke and in those with >3 concomitant drugs. We observed a greater use of imatinib (61.1%) in patients diagnosed in 2018-2019 compared to 2012-2017 (53.2%; p = .002). In multivariable analysis, factors correlated with imatinib use were age > 65 years, spleen size, the presence of comorbidities, and ≥3 concomitant medications. CONCLUSIONS This observational study of almost 2000 cases of CML shows that imatinib is the frontline drug of choice in 55% of Italian patients with CP-CML, with 2G-TKIs prevalently used in younger patients and in those with no concomitant clinical conditions. Introduction of the generic formulation in 2018 seems to have fostered imatinib use.

Abstract
Here we describe the rationale and design of MAJIC, a phase III, prospective, multicenter, randomized trial comparing the combination of the BTK inhibitor acalabrutinib plus the BCL2 inhibitor venetoclax versus the combination of venetoclax plus obinutuzumab as frontline treatment for chronic lymphocytic leukemia or small lymphocytic lymphoma. In both treatment arms, disease response (assessed by International Workshop on Chronic Lymphocytic Leukemia criteria) and minimal residual disease will be used to guide therapy duration, with all patients ultimately discontinuing treatment after a maximum of 2 years. The primary end point is progression-free survival. Key secondary end points include rates of undetectable minimal residual disease, overall response and overall survival. This study will address key unanswered questions in frontline chronic lymphocytic leukemia/small lymphocytic lymphoma therapy by investigating the optimal duration of finite treatment and identifying the optimal venetoclax doublet regimen.

Abstract
BACKGROUND RET fusions are present in 1%-2% of non-small cell lung cancer (NSCLC). Pralsetinib, a highly potent, oral, central nervous system-penetrant, selective RET inhibitor, previously demonstrated clinical activity in patients with RET fusion-positive NSCLC in the phase I/II ARROW study, including among treatment-naïve patients. We report an updated analysis from the ARROW study. PATIENTS AND METHODS ARROW is a multi-cohort, open-label, phase I/II study. Eligible patients were ≥18 years of age with locally advanced or metastatic solid tumours and an Eastern Cooperative Oncology Group performance status 0-2 (later 0-1). Patients initiated pralsetinib at the recommended phase II dose of 400 mg once-daily (QD) until disease progression, intolerance, consent withdrawal, or investigator's decision. The co-primary endpoints (phase II) were overall response rate (ORR) by blinded independent central review and safety. RESULTS Between 17 March 2017 and 06 November 2020 (data cutoff), 281 patients with RET fusion-positive NSCLC were enrolled. The ORR was 72% (54/75; 95% CI, 60-82) for treatment-naïve patients and 59% (80/136; 95% CI, 50-67) for patients with prior platinum-based chemotherapy (enrolment cutoff for efficacy analysis: 22 May 2020); median duration of response was not reached for treatment-naïve patients and 22.3 months for prior platinum-based chemotherapy patients. Tumour shrinkage was observed in all treatment-naïve patients and in 97% of patients with prior platinum-based chemotherapy; median progression-free survival was 13.0 and 16.5 months, respectively. In patients with measurable intracranial metastases, the intracranial response rate was 70% (7/10; 95% CI, 35-93); all had received prior systemic treatment. In treatment-naïve patients with RET fusion-positive NSCLC who initiated pralsetinib by the data cutoff (n = 116), the most common Grade 3-4 treatment-related adverse events (TRAEs) were neutropenia (18%), hypertension (10%), increased blood creatine phosphokinase (9%), and lymphopenia (9%). Overall, 7% (20/281) discontinued due to TRAEs. CONCLUSIONS Pralsetinib treatment produced robust efficacy and was generally well tolerated in treatment-naïve patients with advanced RET fusion-positive NSCLC. Results from the confirmatory phase III AcceleRET Lung study (NCT04222972) of pralsetinib versus standard of care in the first-line setting are pending.

Abstract
Aim: To understand the burden of treatment-naive peripheral T-cell lymphoma (PTCL). Methods: A systematic literature review was conducted in November 2020 following best practice methodology. Results: Fifty-five clinical studies were included, mostly investigating cyclophosphamide, doxorubicin, vincristine and prednisone (CHOP) or 'CHOP-like' regimens, with combination regimens showing similar effectiveness to CHOP alone. Aside from the combination of brentuximab vedotin + cyclophosphamide, doxorubicin and prednisone (A+CHP), other available treatments showed no statistically significant benefit over CHOP in terms of overall or progression-free survival in overall PTCL patients. The mean monthly cost per patient in the USA ranged from $6328 to $9356 based on six studies. One economic evaluation demonstrated A+CHP to be a more cost-effective treatment option than CHOP. Conclusion: Further research is needed to understand the humanistic and cost impact of frontline treatment for PTCL and its specific subtypes.

Abstract
The role of autologous hematopoietic stem cell transplantation (auto-HSCT) following high-dose chemotherapy has been validated and accepted as a standard treatment for patients with relapsed diffuse large B-cell lymphoma (DLBCL). However, its clinical efficacy as frontline therapy remains to be elucidated. This study aimed to examine the feasibility of frontline auto-HSCT for newly diagnosed intermediate/high-risk DLBCL patients. We retrospectively reviewed the data of 223 patients treated with frontline auto-HSCT or chemotherapy alone (year 2008-2014) from four hospitals. The median follow-up time was 29.4 months. Between the two treatment arms among the intermediate/high-risk DLBCL patients, the 3-year overall survival (OS) and progression-free survival (PFS) rates of patients given frontline auto-HSCT were 87.6% and 81.9%, respectively, and the chemotherapy-alone group showed 3-year OS and PFS rates of 64.9% and 59.59%, respectively. Compared with the chemotherapy-alone group, the frontline auto-HSCT could eliminate the adverse impact of non-germinal center B-cell (GCB) type. In addition, in the frontline auto-HSCT group, patients who achieved complete response (CR) at auto-HSCT had a longer survival time than those who did not achieve CR. Our results suggested that frontline auto-HSCT could improve the prognosis of intermediate/high-risk DLBCL patients.

Abstract
Chronic lymphocytic leukemia (cll) is the most commonly diagnosed adult leukemia in Canada. Biologic heterogeneity of cll between patients results in variable disease trajectories and responses to therapy. Notably, compared with patients lacking high-risk features, those with such features-such as deletions in chromosome 17p, aberrations in the TP53 gene, or unmutated immunoglobulin heavy chain variable region genes-experience inferior outcomes and responses to standard chemoimmunotherapy. Novel agents that target the B cell receptor signalling pathway, such as Bruton tyrosine kinase (btk) inhibitors, have demonstrated clinical efficacy and safety in patients with treatment-naïve cll, particularly those with high-risk features. However, given the current lack of head-to-head trials comparing btk inhibitors, selection of the optimal btk inhibitor for patients with cll is unclear and requires consideration of multiple factors. In the present review, we focus on the efficacy, safety, and pharmacologic features of the btk inhibitors that are approved or under clinical development, and we discuss the practical considerations for the use of those agents in the Canadian treatment landscape.

Abstract
We investigate the impact of granulocyte-colony stimulating factor (G-CSF) primary prophylaxis (G-PP, N = 83) versus no G-PP (N = 579) on safety and efficacy of brentuximab vedotin plus doxorubicin, vinblastine, and dacarbazine (A + AVD) in the ECHELON-1 study of previously untreated stage III/IV classical Hodgkin lymphoma. G-PP was associated with lower incidence of ≥ grade 3 neutropenia (29% versus 70%) and febrile neutropenia (11% versus 21%). Fewer dose delays (35% versus 49%), reductions (20% versus 26%), and hospitalizations (29% versus 38%) were observed. Seven neutropenia-associated deaths occurred in the A + AVD arm; none received G-PP. A + AVD with G-PP was associated with decreased risk of a modified progression-free survival event by 26% compared with A + AVD alone (95% CI: 0.40-1.37). G-PP reduced the rate and severity of adverse events, including febrile neutropenia, reduced treatment delays, dose reductions, and discontinuations, and may thus improve efficacy outcomes. These data support G-PP for all patients treated with A + AVD.

Abstract
Multiple myeloma (MM) is a chronically managed blood cancer with a median age of 69 years at the time of diagnosis. Although high dose melphalan and autologous stem cell transplantation (ASCT) remains a standard of care for eligible patients, more than half of the newly diagnosed MM patients are deemed ineligible due to comorbidities or complications of the disease by itself. In this setting, where ASCT is deemed inappropriate, patients could still achieve durable and deep responses if given the appropriate treatment plan. The key concepts of optimizing induction and maintenance strategies while minimizing side-effects are discussed in this review, especially in the context of employing novel agent combinations. It is important to understand the balance between safety and efficacy for each regimen, utilizing maintenance strategy and the best supportive care measures (bone health, infection prevention, and treatment, pain management, etc.). Here, we examine the evidence behind each of those principles and review results from clinical trials for transplant-ineligible (TI) MM.

Abstract
Introduction: Management of multiple myeloma (MM) has improved over recent years. Health-related quality of life (HRQoL) data is becoming increasingly important, owing to improved survival outcomes. Areas covered: The authors performed an expert review of the literature to identify evidence-based data available on HRQoL in frontline and relapsed/refractory MM (RRMM) patients. Expert opinion: De-novo patients should be informed that the HRQoL is expected to improve during first-line treatment with different degrees of possible deterioration during the first cycles. Achievement of a maximal response should be strongly considered, particularly in the frontline setting, but must also be balanced with tolerability, HRQoL, and patient preferences. The same degree of improvement in HRQoL cannot be expected during conventional relapse treatments, where patients should be prepared only for stabilization of HRQoL. However, focusing attention only on measures such as toxicity may provide just a partial view of overall treatment effectiveness. Nonetheless, the authors believe the added value of taking into consideration the patient's perspectives and the importance of patient-reported outcomes in the evaluation of treatment effects should be considered mandatory. The incorporation of quality of life assessment into clinical and research practice has the potential of improving treatment outcomes.

Abstract
Although the majority of patients with diffuse large B-cell lymphoma (DLBCL) can be cured with the standard immunochemotherapy R-CHOP, one-third of them relapses with a dismal outcome in most cases. In the recent years, remarkable advances have been achieved based on the discovery of molecular genetics in DLBCL. In addition to the major cell-of-origin designations of germinal center B-cell and activated B-cell subtypes, next-generation sequencing has unveiled the remarkable complexity of DLBCL and identified potential molecular targets for tailored therapies. Despite these findings, the current standard of care for DLBCL patients is still R-CHOP, and optimization of frontline therapy remains an important goal. In this review, we summarize recent updates on the evolution of frontline therapies for DLBCL.

Abstract
There is limited data regarding the efficacy and safety of lenalidomide, adriamycin and dexamethasone (RAD) combination on newly diagnosed multiple myeloma (NDMM) patients. There is also scarce information about the effect of lenalidomide on bone metabolism and angiogenesis in NDMM. Thus, we conducted a Phase 2 study to evaluate the efficacy and safety of RAD regimen as induction in transplant-eligible NDMM patients and we studied the effects on bone metabolism and angiogenesis. A total of 45 patients were enrolled. Following four cycles of RAD, the overall response rate was 66.7% and after a median follow up of 29.1 months (range 21.0-34.9), the median survival outcomes have not been reached yet. RAD had a favorable toxicity profile and did not impair stem cell collection. RAD significantly reduced bone resorption markers CTX (p = 0.03) and TRACP-5b (p < 0.01). Interestingly, RAD also increased bone formation markers bone-specific alkaline phosphatase (p = 0.036), procollagen type 1 amino-terminal propeptide (p = 0.028) and osteocalcin (p = 0.026), which has not been described before with lenalidomide-containing regimens in the absence of bortezomib coadministration. Furthermore, the angiogenic cytokines VEGF (p = 0.01), angiogenin (p = 0.02) and bFGF (p < 0.01) were significantly reduced post-RAD induction. Our results suggest that RAD is an effective induction regimen before autologous stem cell transplantation with beneficial effects on bone metabolism and angiogenesis.

Abstract
Chronic lymphocytic leukemia (CLL) is the most prevalent leukemia in the adult population. Current efforts are focused on better understanding the intricate pathophysiology of the disease to develop successful targeted therapies. Ibrutinib is emerging as an important agent in this new age of targeted treatment for CLL. As a Bruton’s tyrosine kinase inhibitor, it blocks the signaling pathway that malignant B-lymphocytes need for growth and maturation. Ibrutinib’s role in therapy was further expanded recently when the US Food and Drug Administration approved its use in both frontline and salvage treatment for patients with CLL. This review assesses the effectiveness of ibrutinib in the frontline setting, its efficacy in various types of patients with CLL, and its safety and tolerability.

Abstract
BACKGROUND The authors examined the "real-world" effectiveness of rituximab (R) maintenance therapy (R-maintenance) compared with observation after R-based induction therapy in patients with previously untreated follicular lymphoma (FL) in the United States. METHODS The National LymphoCare Study is a prospective, multicenter, observational study that enrolled > 2700 untreated patients with FL diagnosed from 2004 to 2007 at 265 sites in the United States. Among these, patients who achieved at least stable disease after R-based induction therapy were eligible for the current analysis. Patients who initiated R-maintenance within 215 days of completing induction therapy were categorized as the R-maintenance group, and those who did not initiate therapy during this period were categorized as the observation group. The objective of the current study was to determine the effect of R-maintenance on progression-free survival (PFS), time to next treatment (TTNT), and overall survival (OS). RESULTS A total of 1439 patients completed R-based induction therapy, 1186 of whom met all inclusion criteria (541 patients received R-maintenance and 645 patients were observed). Characteristics that were found to be predictive of receiving R-maintenance were histology grade (1/2), Ann Arbor stage of disease (III/IV), geographic region (region other than the West), and practice setting (community practice). With a median follow-up of 5.7 years, R-maintenance was associated with superior PFS (hazards ratio [HR], 0.68; 95% confidence interval [95% CI], 0.56-0.84 [P = .0003]) and TTNT (HR, 0.66; 95% CI, 0.52-0.84 [P = .0007]). No significant difference in OS was observed (HR, 0.81; 95% CI, 0.58-1.14 [P = .23]). CONCLUSIONS R-maintenance in patients with FL and at least stable disease after R-based induction therapy provided significantly longer PFS and TTNT in comparison with observation, but no significant difference in OS was observed with 5-years of follow-up. This comparative effectiveness study aligns with the results of randomized trials suggesting that similar outcomes occur with R-maintenance in FL with the treatment variations observed in clinical practice.

Abstract
The development of imatinib has revolutionized the treatment of chronic myeloid leukemia. Follow-up analysis of IRIS trial participants continues to demonstrate durable responses for imatinib at 400 mg/day. However, 10%-15% of patients with chronic myeloid leukemia will become imatinib-resistant or intolerant of adverse events. Phase II studies have shown that most of these patients will respond to second-generation tyrosine kinase inhibitors, such as nilotinib, dasatinib, and bosutinib. Both nilotinib and dasatinib have recently demonstrated clinical efficacy as frontline therapy in Phase III studies. In the ENESTnd trial, nilotinib 600-800 mg/day produced significantly higher major molecular rates and complete cytogenetic response rates in comparison with imatinib at 12 months. Recently, 18-month follow-up analysis of this trial continues to demonstrate superiority for nilotinib. It is unknown whether this will ultimately translate into improved long-term outcomes, such as event-free survival or overall survival. Nilotinib continues to be generally well tolerated and tends to produce less Grade 3/4 toxicity in frontline therapy when compared with its use following imatinib failure. With three tyrosine kinase inhibitors for potential frontline therapy and an active drug discovery pipeline, treatment for chronic myeloid leukemia is still subject to change with time as clinical algorithms continue to evolve.
