RESUMO
Aim: To compare the effectiveness of in-class transition to all-oral ixazomib-lenalidomide-dexamethasone (IRd) following parenteral bortezomib (V)-based induction versus continued V-based therapy in US oncology clinics. Patients & methods: Non-transplant eligible patients with newly diagnosed multiple myeloma (MM) receiving in-class transition to IRd (N = 100; US MM-6), or V-based therapy (N = 111; INSIGHT MM). Results: Following inverse probability of treatment weighting, overall response rate was 73.2% with IRd versus 57.5% with V-based therapy (p < 0.0001). Median duration of treatment was 10.8 versus 5.3 months (p < 0.0001). Overall, 18/24% of patients discontinued IRd/V-based therapy due to adverse events. Conclusion: IRd after V-based induction was associated with significantly improved overall response rate and duration of treatment than continued V-based combination therapy. Clinical Trial Registration: US MM-6: NCT03173092; INSIGHT MM: NCT02761187 (ClinicalTrials.gov).

WHAT IS THIS SUMMARY ABOUT?: The aim of this plain language review article is to help you to understand biosimilar medicines (called biosimilars) by giving a summary of biologic medicines and biosimilars. It is based on the experience of an international panel of physicians with expertise on biosimilars who discussed and agreed on the topics and information included in this review article. Biologic medicines are medicines that come from living organisms such as bacteria and animal or plant cells. Biosimilars are a group of approved biologic medicines that are similar to original biologic medicines that are already available. This review explains how biosimilars are developed and approved, and how they are used to treat people with cancer. It also answers some common important questions people with cancer might have when taking biosimilars. The purpose of this plain language review is to help you to understand the findings from recent research. This review reports information from peer-reviewed literature and other sources available in the public domain (e.g., regulatory documents or product information labels). The findings may differ from those of other review articles. Health professionals should make treatment decisions based on all available evidence.

PURPOSE: Radiation therapy (RT) is an important treatment modality for patients with multiple myeloma (MM). Although patients are living longer with MM, they are more likely to have comorbidities related to treatment, such as bone pain; however, RT can provide symptom relief. To date, the characterization of patients who have received RT in the real-world setting has been limited. METHODS AND MATERIALS: The Connect® MM Registry is a large, US multicenter, prospective observational cohort study of adult patients with newly diagnosed MM from mostly community sites. RT utilization and outcomes were analyzed quarterly throughout treatment. Factors associated with RT use were identified via multivariable analysis. RESULTS: A total of 3011 patients were enrolled in the Connect MM Registry with 903 patients (30%) having received RT at any time. There was a significant difference (P < .05) in overall RT use among patients with an Eastern Cooperative Oncology Group performance status of 0 to 1 versus ≥2, International Staging System disease stage I/II versus III, a history of plasmacytoma or a novel agent in their first regimen, and any number of bone lesions or severe osteoporosis/fracture. RT use was associated with having bone lesions or severe osteoporosis (vs not having bone lesions). Additionally, RT use was associated with ethnicity (Hispanic vs not) and Connect MM Registry cohort (cohort 1 [enrolled 2009-2011] vs 2 [enrolled 2012-2016]). In the 6 months before death, increased RT use was associated with increasing number of treatment lines (P < .0001) and high- versus standard-risk disease (per International Myeloma Working Group criteria; P = .0028). CONCLUSIONS: Real-world results from the Connect MM Registry show RT is frequently used and is associated with clinical factors, including performance status and disease stage. Earlier in MM diagnosis, RT may be used as an adjunct to palliate symptoms or delay systemic therapy. Toward the end of life, RT is more frequently used for palliation when treatment options are often limited.

Deeper responses are associated with longer survival in multiple myeloma (MM); however, limited data exist on the impact of response kinetics on outcomes. We investigated progression-free survival (PFS) and duration of response (DOR) by response depth and in early (best confirmed response 0-4 months; n = 424) versus late responders (best confirmed response >4 months; n = 281). Newly diagnosed patients enrolled in TOURMALINE-MM2 receiving ixazomib-lenalidomide-dexamethasone (IRd) (n = 351) or placebo-Rd (n = 354) were evaluated post hoc. Deeper responses were associated with longer PFS (complete response [CR] not reached [NR], very good partial response [VGPR] 37.2 months, partial response [PR] 16.4 months) and DOR (CR NR, VGPR 42.6 months, PR 15.4 months). Among patients with a PFS (n = 511) or DOR (n = 484) of ≥6 months who achieved ≥PR, median PFS was prolonged among late versus early responders receiving IRd (59.7 vs. 17.9 months) or placebo-Rd (56.6 vs. 12.4 months), as was median DOR (IRd, NR vs. 20.9 months; placebo-Rd, 58.2 vs. 11.7 months). While the treatment paradigm for newly diagnosed MM is treatment to progression, our findings suggest slowness of response to a proteasome inhibitor-immunomodulatory drug-steroid combination is not a negative predictor of outcome.
RESUMO
Long-term proteasome inhibitor (PI) treatment can improve multiple myeloma (MM) outcomes, but this can be difficult to achieve in clinical practice due to toxicity, comorbidities, and the burden of repeated parenteral administration. US MM-6 (NCT03173092) enrolled transplant-ineligible patients with newly diagnosed MM to receive all-oral ixazomib-lenalidomide-dexamethasone (IRd; ≤39 cycles or until progression or toxicity) following three cycles of bortezomib-based induction. Primary endpoint: 2-year progression-free survival (PFS). Key secondary/exploratory endpoints included overall response rate (ORR), overall survival (OS), safety, quality of life (QoL), treatment satisfaction, and actigraphy. At datacut, in the fully accrued cohort of 140 patients, median age was 73 years with 42% aged ≥75 and 61% deemed frail; 10% of patients were ongoing on treatment. After a median follow-up of 27 months, the 2-year PFS rate was 71% (95% confidence interval: 61-78). ORR increased from 62% at the end of induction to 80% following in-class transition (iCT) to IRd for a median of 11 months. The 2-year OS rate was 86%. The overall safety profile/actigraphy levels were consistent with previous reports; QoL/treatment satisfaction scores were stable with ongoing therapy. iCT to IRd may allow prolonged PI-based therapy with promising efficacy and a tolerable safety profile, while maintaining QoL.

BACKGROUND: Infections are a common reason for hospitalization and death in multiple myeloma (MM). Although pneumococcal vaccination (PV) and influenza vaccination (FV) are recommended for MM patients, data on vaccination status and outcomes are limited in MM. MATERIALS AND METHODS: We utilized data from the global, prospective, observational INSIGHT MM study to analyze FV and PV rates and associated outcomes of patients with MM enrolled 2016-2019. RESULTS: Of the 4307 patients enrolled, 2543 and 2500 had study-entry data on FV and PV status. Overall vaccination rates were low (FV 39.6%, PV 30.2%) and varied by region. On separate multivariable analyses of overall survival (OS) by Cox model, FV in the prior 2 years and PV in the prior 5 years impacted OS (vs. no vaccination; FV: HR, 0.73; 95% CI, 0.60-0.90; Pâ¯=â¯.003; PV: HR, 0.51; 95% CI, 0.42-0.63; P < .0001) when adjusted for age, region, performance status, disease stage, cytogenetics at diagnosis, MM symptoms, disease status, time since diagnosis, and prior transplant. Proportions of deaths due to infections were lower among vaccinated versus non-vaccinated patients (FV: 9.8% vs. 15.3%, Pâ¯=â¯.142; PV: 9.9% vs. 18.0%, Pâ¯=â¯.032). Patients with FV had generally lower health resource utilization (HRU) versus patients without FV; patients with PV had higher or similar HRU versus patients without PV. CONCLUSION: Vaccination is important in MM and should be encouraged. Vaccination status should be recorded in prospective clinical trials as it may affect survival. This trial was registered at www. CLINICALTRIALS: gov as #NCT02761187.

BACKGROUND: Adults with triple-class refractory (TCR) multiple myeloma (MM) have limited treatment options and poor prognosis, but the burden of TCR MM has not been well characterized. This study evaluated treatment patterns, overall survival (OS), health-related quality of life (HRQoL), and healthcare resource use (HCRU) among patients with TCR MM in US clinical practice. PATIENTS AND METHODS: Patients with TCR MM in the Connect MM Registry (NCT01081028; a large, US, multicenter, prospective observational cohort study of patients with newly diagnosed MM) were included. Patient characteristics, treatment patterns, HRQoL, and HCRU were analyzed using descriptive statistics. OS was calculated using Kaplan-Meier methodology for the overall cohort and for patients with/without ≥1 post-TCR line of therapy (LOT). RESULTS: A total of 232 patients with TCR MM were included; 155 (67%) had ≥1 post-TCR LOT (post-TCR-Treated subgroup; median 9.9 months of follow-up). Most common post-TCR treatments were carfilzomib (47%), pomalidomide (40%), and daratumumab (26%); median treatment duration was 3.3 months. Median OS was 9.9 months in the overall population, 10.8 months in post-TCR-Treated patients, and 2.6 months for those with no new post-TCR LOT. HRQoL deteriorated and pain increased over 1 year of follow-up, with clinically meaningfully changes in EQ-5D (mean, -0.06 points) and FACT-G (mean, -9.9 points). 124 (53%) patients had ≥1 all-cause hospitalization and 58 (25%) had ≥1â¯MM-related hospitalization; median annualized length of stay was 35.3 and 42.9 days, respectively. CONCLUSION: The burden of TCR MM is substantial, emphasizing the need for more effective treatment options in the TCR setting.

In the primary analysis of LYRA, daratumumab + cyclophosphamide/bortezomib/dexamethasone (DARA + CyBorD) was effective and well tolerated in newly diagnosed multiple myeloma (NDMM) and relapsed multiple myeloma (RMM). We report the final analysis of LYRA (median months of follow-up: NDMM, 35.7; RMM, 35.3) after all patients completed study therapy, were followed for 36 months, or discontinued. Patients received DARA + CyBorD induction, autologous stem cell transplant (if eligible), and 12 months of daratumumab maintenance. Eighty-seven NDMM patients enrolled, 39 underwent transplant, and 63 completed maintenance. Rates of complete response or better were 48.7% and 29.8% for NDMM transplant and NDMM non-transplant patients, respectively, and 36-month progression-free survival rates were 69.3% and 72.6%. Grade 3/4 treatment-emergent adverse events occurred in 61.6% of NDMM patients. Efficacy and safety data are also reported for the smaller RMM cohort (n = 14). DARA + CyBorD followed by daratumumab maintenance was well tolerated and achieved deep, durable responses in NDMM and RMM.

PURPOSE: We evaluated the incidence of febrile neutropenia (FN) and related clinical outcomes among patients treated with myelosuppressive chemotherapy for nonmyeloid malignancies who received pegfilgrastim on-body injector (OBI) or other options (Other) for FN prophylaxis. METHODS: In this prospective observational study, adult patients with breast, prostate, or lung cancer, or non-Hodgkin lymphoma at risk for FN were stratified into subgroups based on FN prophylaxis used in the first chemotherapy cycle: pegfilgrastim OBI vs Other (pegfilgrastim or biosimilar pegfilgrastim prefilled syringe, daily filgrastim, or no granulocyte colony-stimulating factor [G-CSF]) for up to 4 planned chemotherapy cycles. RESULTS: This US study enrolled 2575 eligible patients (OBI, 1624; Other, 951). FN incidence was lower in the OBI group (6.4% [95% CI, 5.2-7.6%]) than in the Other group (9.4% [7.5-11.2%]), with a relative risk (RR) of 0.66 (0.47-0.91; p = .006). A decreased risk of dose delays among patients receiving pegfilgrastim OBI vs Other was observed (RR for ≥ 5 days: 0.64 [0.42-0.96], p = .023; RR for ≥ 7 days: 0.62 [0.40-0.91], p = .016). Adherence, defined as G-CSF support for all chemotherapy cycles, was 94.0% (92.9-95.2%) in the OBI group compared with 58.4% (55.2-61.5%) in the Other group. Compliance with pegfilgrastim, defined as administration the day after chemotherapy, was 88.3% in the OBI group and 48.8% in the prefilled syringe group. CONCLUSION: Patients receiving pegfilgrastim OBI had a lower incidence of FN compared with those receiving alternatives. The OBI was associated with improved adherence to and compliance with clinically recommended G-CSF prophylaxis.

The availability of biosimilars in oncology has provided an opportunity for increased patient access to biologic therapies. However, healthcare professional perceptions concerning the relatively limited clinical data sufficient to support their regulatory approval may contribute to varied uptake and use. We review key aspects of the development program for the rituximab biosimilar PF-05280586 (Ruxience™) that supported its approval for lymphoid malignancies, to illustrate the rationale for an abbreviated clinical program. In particular, we describe the extensive analytical assessment, comprising sensitive techniques that established similarity with the reference product in key product attributes, underlying structure, function, potency, safety and quality, which formed the foundation for a successful development program, culminating in a confirmatory comparative clinical trial in patients with follicular lymphoma.

BACKGROUND: The t (11;14) (q13;32) translocation [t (11;14)] is present in â¼20% of patients with newly diagnosed multiple myeloma (NDMM), but studies examining its prognostic ability have yielded divergent results, and data are lacking on outcomes from first-line therapy. PATIENTS AND METHODS: Data from the Connect MM Registry, a large US, multicenter, prospective observational cohort study of patients with NDMM were used to examine the effect of t (11;14) status on first-line therapy outcomes in the Overall population (n = 1574) and race groups (African American [AA] vs. non-African American [NAA]). RESULTS: Baseline characteristics were generally similar between patients with (n = 378) and without (n = 1196) t (11;14). Prevalence of t (11;14) was similar by race (AA, 27%; NAA, 24%). In the overall population, regardless of first-line therapy, t (11;14) status did not affect progression-free survival (hazard ratio, 1.02; P = 0.7675) or overall survival (hazard ratio, 0.99; P = .9417). AA patients with t (11;14) had higher likelihood of death (Nominal Cox regression P = .0298) vs. patients without t (11;14). CONCLUSIONS: Acknowledging observational study and inferential limitations, this exploratory analysis of a predominantly community-based population suggests that t (11;14) is a neutral prognostic factor in the general MM population but may be a negative factor for overall survival in AA patients.

Aim: To evaluate the effectiveness and safety of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory multiple myeloma in routine clinical practice. Patients & methods: Patient-level data from the global, observational INSIGHT MM and the Czech Registry of Monoclonal Gammopathies were integrated and analyzed. Results: At data cut-off, 263 patients from 13 countries were included. Median time from diagnosis to start of IRd was 35.8 months; median duration of follow-up was 14.8 months. Overall response rate was 73%, median progression-free survival, 21.2 months and time-to-next therapy, 33.0 months. Ixazomib/lenalidomide dose reductions were required in 17%/36% of patients; 32%/30% of patients discontinued ixazomib/lenalidomide due to adverse events. Conclusion: The effectiveness and safety of IRd in routine clinical practice are comparable to those reported in TOURMALINE-MM1. Clinical trial registration: NCT02761187 (ClinicalTrials.gov).
Lay abstract Proteasome inhibitors are drugs used in multiple myeloma (MM), a blood cancer that develops from cells in the bone marrow. Ixazomib is the first oral proteasome inhibitor to be approved for use in MM, when given in combination with two other oral drugs, lenalidomide and dexamethasone, to adult patients who have received one prior therapy. Our study, which was conducted in routine clinical practice, found that the effectiveness and safety of ixazomib + lenalidomide + dexamethasone in previously treated MM patients were similar to those seen in the Phase III clinical trial on which approval was based. These findings are important because they suggest that MM patients in everyday practice can achieve the same benefits from this treatment as patients in clinical trials, despite often being in poorer health.

Continuous lenalidomide-dexamethasone (Rd)-based regimens are among the standards of care in transplant-ineligible newly diagnosed multiple myeloma (NDMM) patients. The oral proteasome inhibitor ixazomib is suitable for continuous dosing, with predictable, manageable toxicities. In the double-blind, placebo-controlled TOURMALINE-MM2 trial, transplant-ineligible NDMM patients were randomized to ixazomib 4 mg (n = 351) or placebo (n = 354) plus Rd. After 18 cycles, dexamethasone was discontinued and treatment was continued using reduced-dose ixazomib (3 mg) and lenalidomide (10 mg) until progression/toxicity. The primary endpoint was progression-free survival (PFS). Median PFS was 35.3 vs 21.8 months with ixazomib-Rd vs placebo-Rd, respectively (hazard ratio [HR], 0.830; 95% confidence interval, 0.676-1.018; P = .073; median follow-up, 53.3 and 55.8 months). Complete (26% vs 14%; odds ratio [OR], 2.10; P < .001) and ≥ very good partial response (63% vs 48%; OR, 1.87; P < .001) rates were higher with ixazomib-Rd vs placebo-Rd. In a prespecified high-risk cytogenetics subgroup, median PFS was 23.8 vs 18.0 months (HR, 0.690; P = .019). Overall, treatment-emergent adverse events (TEAEs) were mostly grade 1/2. With ixazomib-Rd vs placebo-Rd, 88% vs 81% of patients experienced grade ≥3 TEAEs, 66% vs 62% serious TEAEs, and 35% vs 27% TEAEs resulting in regimen discontinuation; 8% vs 6% died on study. Addition of ixazomib to Rd was tolerable with no new safety signals and led to a clinically meaningful PFS benefit of 13.5 months. Ixazomib-Rd is a feasible option for certain patients who can benefit from an all-oral triplet combination. This trial was registered at www.clinicaltrials.gov as #NCT01850524.

Although new multiple myeloma (MM) therapies are effective in alleviating some disease-associated symptoms (e.g. bone pain, fatigue, functional decline), they can result in additional toxicities, further impacting health-related quality of life (HRQoL). Here, we compared HRQoL and safety of lenalidomide-bortezomib-dexamethasone [RVd (n = 445)], bortezomib-melphalan-prednisone [VMP (n = 77)] and Vd or VMP (n = 588) in patients with newly diagnosed MM (NDMM) from the Connect® MM Registry, a large, USA, multicentre, prospective observational cohort study. Functional Assessment of Cancer Therapy-Multiple Myeloma subscale, EuroQol-5D overall score and Bone Pain Inventory HRQoL scores were significantly improved with RVd versus Vd/VMP. Serious adverse event rates were similar in all groups. Treatment with RVd maintained HRQoL in this real-world, largely community-based population of patients with NDMM.

BACKGROUND: The ongoing US MM-6 study is investigating in-class transition (iCT) from parenteral bortezomib-based induction to all-oral IRd (ixazomib-lenalidomide-dexamethasone) with the aim of increasing proteasome inhibitor (PI)-based treatment adherence and duration while maintaining patients' health-related quality of life (HRQoL) and improving outcomes. PATIENTS AND METHODS: US community sites are enrolling non-transplant-eligible patients with newly diagnosed multiple myeloma (MM) with no evidence of progressive disease after 3 cycles of bortezomib-based therapy to receive IRd (up to 39 cycles or until progression or toxicity). The patients use mobile or wearable digital devices to collect actigraphy (activity and sleep) data and electronically complete HRQoL, treatment satisfaction and medication adherence questionnaires. The primary endpoint is progression-free survival. The key secondary endpoints include response rates and therapy duration. RESULTS: At the data cutoff, 84 patients had been treated (median age 73 years; 44% aged ≥ 75 years; 49% men; 15% Black or African American; and 10% Hispanic or Latino). Of the 84 patients, 62% were continuing therapy. The mean duration of total PI therapy was 10.1 months and for the IRd regimen was 7.3 months. With an 8-month median follow-up, the 12-month progression-free survival rate was 86% (95% confidence interval, 73%-93%) from both the start of bortezomib-based treatment and the start of IRd. The overall response rate was 62% (complete response, 4%; very good partial response, 25%; partial response, 33%) after bortezomib-based induction and 70% (complete response, 26%; very good partial response, 29%; partial response, 15%) after iCT. The IRd safety profile was consistent with previous clinical trial data, and HRQoL and treatment satisfaction were maintained. CONCLUSION: The patients included in the US MM-6 study are representative of the real-world US MM population. The use of iCT might permit prolonged PI-based therapy with promising efficacy, without impacting patients' HRQoL or treatment satisfaction.

BACKGROUND: Studies have reported racial disparities in access to and use of multiple myeloma (MM) treatments between African American (AA) and White patients. Although AA patients demonstrate longer disease-specific survival, this has not uniformly translated into improved survival over time. The association between race and treatment patterns and survival outcomes was analyzed using data from the Connect MM Registry. METHODS: The Connect MM Registry is a large US, multicenter, prospective observational cohort study of patients with newly diagnosed MM. Patients who received first-line (1L) stem cell transplantation (SCT) or who did not receive SCT (non-SCT or non-stem cell transplantation [NSCT]) were grouped by raceEffects of race and transplantation status on the use of triplet treatment were estimated using logistic regression. RESULTS: Treatment patterns in 1L (types and duration of induction, posttransplantation maintenance) were similar between AA and White patients. SCT rates in 1L (32% vs 36%) and triplet treatment use (AA: 44% for NSCT patients and 72% for SCT patients; and White: 48% for NSCT patients and 72% for SCT patients) during first induction were similar. No significant effect of race or transplantation status on 1L triplet treatment use was observed. Race was not found to be associated with survival outcomes among patients who underwent NSCT; however, AA patients who received SCT had significantly longer overall survival compared with White patients who underwent SCT (not reached vs 88.2 months; hazard ratio, 0.56; 95% CI, 0.35-0.89 [P = .0141]). CONCLUSIONS: AA and White patients were found to have similar treatment patterns in the Connect MM Registry, suggesting that both groups had equal access to health care. In this real-world setting, AA patients received standard-of-care treatment, which might have contributed to better MM-specific survival compared with White patients.

BACKGROUND: The Surveillance, Epidemiology, and End Results (SEER) database and National Cancer Database (NCDB) show improved overall survival (OS) in patients with multiple myeloma (MM) over the last 15 years. This analysis evaluated the validity of the largely community-based Connect MM Registry as a national reference for MM. METHODS: Baseline disease characteristics and survival in US newly diagnosed MM patients were examined using the Connect MM Registry as well as SEER and NCDB databases. Baseline characteristics predictive of longer survival in Connect MM were also identified. RESULTS: As of February 2017, 3011 patients were enrolled in the Connect MM Registry; 2912 were treated. Median age at time of MM diagnosis and age range were numerically similar from 2010 to 2015 across all 3 registries; SEER had a higher representation of nonwhite racial groups than that in the other 2 registries. OS rates suggest proportionate improvement with year of diagnosis among the 3 registries. A Cox proportional hazards model suggests that younger age (<65 years) is associated with longer survival (vs ≥75; HR, 0.39; 95% confidence interval, 0.34-0.46) in the Connect MM Registry. However, sex (HR, 0.91; P = .15) and race (black vs white; HR, 0.88; P = .21) were not associated with longer OS. CONCLUSIONS: Data from the Connect MM Registry appear to be largely representative of national trends, comprehensive, and reliable representations of the national MM population. Baseline characteristics were comparable, and survival similarly improved over time among the 3 registries. CLINICALTRIALS. GOV, IDENTIFIER: NCT01081028.

OBJECTIVES: This observational study identified attributes of patient-reported satisfaction with therapy for multiple myeloma (MM), described the treatment-related time burden and indirect costs, and investigated the effect of administration route (oral vs. injectable) on these outcomes among patients with newly diagnosed MM (NDMM) and among caregivers. METHODS: Patients residing in the USA with a self-reported diagnosis of NDMM were recruited from PatientsLikeMe, MyelomaCrowd, and Facebook (16 December 2016 and 6 July 2017) to complete an electronic survey including questions on treatment experience, economic burden, and standardized patient-reported outcome measures, including the Treatment Satisfaction Questionnaire for Medication with three domains (global satisfaction, effectiveness, and convenience) and the Work Productivity and Activity Impairment Questionnaire. Univariate and multivariate analyses identified predictors of patient-perceived treatment satisfaction. RESULTS: Among 188 patients, worse Eastern Cooperative Oncology Group performance status (ECOG PS) was correlated with lower patient-perceived effectiveness and convenience of their current treatment. White race and oral administration route were independently correlated with higher patient-perceived convenience of treatment. Injectable therapy use was associated with a trend towards increased activity impairment (43 vs. 34%; p = 0.05) and significantly higher time burden of treatment administration, with threefold higher adjusted indirect costs of MM therapy compared with solely orally administered therapies (monthly mean $US482 vs. 153; 2016 values; p < 0.0001). CONCLUSIONS: Factors associated with patient-perceived satisfaction with NDMM treatment-ECOG PS, race, administration route-warrant increased attention in shared treatment decision making to help identify patient needs and improve the patient's treatment experience. The use of orally administered therapies could improve patients' activity impairment and reduce the time burden associated with therapy.
