Updated Health-Related Quality of Life Results from the KarMMa Clinical Study in Patients with Relapsed and Refractory Multiple Myeloma Treated with the B-Cell Maturation Antigen-Directed Chimeric Antigen Receptor T Cell Therapy Idecabtagene Vicleucel (ide-cel, bb2121)

Abstract Introduction: Patients with heavily pretreated relapsed and refractory multiple myeloma (RRMM) have poor outcomes and poor health-related quality of life (HRQoL). The B-cell maturation antigen (BCMA)-directed chimeric antigen receptor (CAR) T cell therapy ide-cel has shown frequent, deep, and durable responses in patients with RRMM who were triple-class exposed (TCE) to immunomodulatory drugs, proteasome inhibitors (PI), and anti-CD38 monoclonal antibodies in the pivotal, phase 2, single-arm KarMMa trial (Munshi NC, et al. N Engl J Med 2021;384:705-716). Ide-cel is approved in the US by the FDA for the treatment of adults with RRMM after ≥ 4 prior lines of therapy, including an immunomodulatory drug, PI, and anti-CD38 monoclonal antibody. We have shown previously that in the KarMMa trial, ide-cel provides clinically meaningful benefits in HRQoL at 9 months' follow-up (Delforge M, et al. HemaSphere 2020;4(suppl 1). Abstract EP1000; Shah N, et al. Blood 2020;136(suppl 1):28-29). The aim of this analysis was to extend previous reports by analyzing the effect of ide-cel on HRQoL at 24 months post-infusion data cut off (December 21, 2020) in patients with TCE RRMM in the KarMMa trial. Methods: In the KarMMa trial (NCT03361748), eligible patients had ≥ 3 prior antimyeloma treatment regimens, were TCE, and refractory to their last treatment regimen per International Myeloma Working Group criteria. To assess HRQoL, European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ) C30 (QLQ-C30), EORTC QLQ Multiple Myeloma Module (QLQ-MY20) and EuroQoL 5 dimensions 5 levels (EQ-5D-5L) questionnaires were administered at screening, baseline, at ide-cel infusion, at months 1-6, and every 3-6 months up to month 24 or end of study. Thresholds for clinically meaningful changes from baseline were predefined. Statistical significance was calculated using the 2-sided Wilcoxon signed rank test (0.05 significance level). Results: Of 128 patients treated with ide-cel, 126 (98%) had a baseline and ≥ 1 post-baseline HRQoL assessment and were included in the HRQoL-evaluable population. The patient questionnaire completion rate was ≥ 75% up to month 6 and 50%-70% thereafter for most visits. For the predefined primary HRQoL domains, mean scores improved after ide-cel treatment and were comparable to the general population (Table). Mean changes from baseline exceeded the minimal important difference (MID) threshold for clinically meaningful improvement in fatigue, pain, physical functioning, cognitive functioning, and global health status/quality of life (QoL) scores of QLQ-C30 and disease symptom scores of QLQ-MY20 through month 24 (data cutoff, December 21, 2020). Side effects of treatment (QLQ-MY20) remained stable. Overall, 40%-70% of patients had clinically meaningful improvements in the QLQ-C30 fatigue, pain, physical functioning, and global health status/QoL scores at later timepoints. Moreover, 30%-40% of patients experienced clinically meaningful improvements in cognitive functioning, disease symptoms, and side effects, with 40%-60% of patients remaining stable in these domains, across most of the post-baseline assessment visits. Predefined secondary HRQoL domains included all other domains from QLQ-C30 and -MY20, EQ-5D-5L health utility index scores, and EQ-5D visual analogue scale (VAS) scores. Mean changes from baseline exceeded the MID thresholds for clinically meaningful improvement and reached statistical significance across most follow-up visits for role functioning, emotional functioning, social functioning, dyspnea, insomnia, constipation, diarrhea (QLQ-C30), future perspectives (QLQ-MY20), health utility index scores (EQ-5D-5L), and VAS scores (EQ-5D). Mean changes from baseline for nausea/vomiting, appetite loss, financial difficulties (QLQ-C30), and body image (QLQ-MY20) scores were not clinically meaningful. At the individual level, most patients remained stable or achieved clinically meaningful improvements in secondary domains of interest across almost all follow-up visits. Conclusion: In this study, patients with TCE RRMM who received a single infusion of ide-cel showed clinically meaningful improvements across multiple HRQoL domains during the 24-month follow-up period.

Introduction: Patients (pts) with transfusion-dependent (TD) β-thalassemia may require long-term red blood cell transfusions (RBCT) that can lead to iron overload and associated complications, which impact negatively on health-related quality of life (HRQoL). Administration of RBCT provides transient relief from anemia-related symptoms associated with β-thalassemia; reduction of RBCT may increase anemia-related symptoms and thereby worsen HRQoL. The phase 3 BELIEVE study (NCT02604433) showed that the first-in-class erythroid maturation agent luspatercept provided clinically meaningful reduction in RBCT burden, but the impact of luspatercept on HRQoL is not well understood. This analysis assessed the effect of luspatercept plus best supportive care (BSC, including RBCT, iron chelation therapy) vs placebo (PBO) plus BSC on HRQoL in pts with TD β-thalassemia. Methods: Pts received luspatercept (starting dose 1.0 mg/kg with titration up to 1.25 mg/kg every 3 weeks) or PBO, subcutaneously for ≥ 48 weeks plus BSC. HRQoL was assessed using the generic 36-item Short Form Health Survey (SF-36) and the thalassemia-specific Transfusion-dependent Quality of Life questionnaire (TranQol), at screening (≤ 4 weeks prior to first study dose) and every 12 weeks up to 48 weeks of treatment. The HRQoL evaluable population included all pts who completed the HRQoL assessment at screening and ≥ 1 post-screening assessment visit. The TranQol and SF-36 were considered complete if ≥ 75% and ≥ 50% of items, respectively, were answered at a given time point. The primary analysis assessed changes from baseline between groups up to Week 48. The primary domains of interest were: TranQol total score and Physical Health (PH); and the SF-36 Physical Component Summary (PCS), Physical Functioning (PF), and General Health (GH). Other domains were considered exploratory domains. Changes from baseline were compared using ANCOVA models adjusting for baseline domain scores and geographic region. In exploratory analyses, the proportion of pts achieving a clinically meaningful improvement in domain scores were compared between pts on luspatercept achieving a clinical response (≥ 50% reduction in RBCT burden over 12 weeks; ≥ 33% reduction in RBCT burden over 12 weeks; transfusion independence [TI] any 8 weeks; or TI any 12 weeks), and PBO. Results: 336 pts were randomized to treatment; 224 to luspatercept and 112 to PBO. The HRQoL evaluable population was 212 (94.6%) in the luspatercept arm and 104 (92.9%) in the PBO arm. HRQoL questionnaire compliance rates among pts still on treatment were > 87.5% for both questionnaires at Week 48. Baseline HRQoL scores were similar to the US general population for most SF-36 domains, although GH, Role-Emotional, and Role-Physical domain scores were impaired in the BELIEVE population. Mean scores on all primary and exploratory domains were stable over time in both treatment groups and did not differ between treatment groups at Week 24 and 48. When considering responders to luspatercept, pts receiving luspatercept and achieving a ≥ 50% reduction in RBCT burden over 12 weeks were significantly more likely than pts receiving PBO to have a clinically meaningful improvement in PCS (31.1% vs 16.5%; P = 0.024), and PF (30.0% vs 13.2%; P = 0.007) at Week 48 (Table). Statistically significant differences between luspatercept and PBO were also seen among pts achieving TI for any 8 or any 12 weeks for some SF-36 domains, but no statistical difference was seen in pts achieving a ≥ 33% reduction in RBCT burden for either SF-36 or TranQol domains although the proportion of pts with improved scores was higher with luspatercept, especially at Week 48. Conclusions: Overall, the addition of luspatercept to BSC reduced transfusion burden while sustaining TranQol and SF-36 HRQoL scores over time through Week 48 compared with those receiving PBO. Pts with TD β-thalassemia responding to luspatercept were more likely to achieve clinically meaningful improvements in HRQoL compared with PBO.

Abstract Introduction: The randomized, phase 3 study ENDEAVOR (NCT01568866; N=929) demonstrated a clinically meaningful and statistically significant improvement in progression-free survival for patients with relapsed or refractory multiple myeloma who were treated with carfilzomib and dexamethasone (Kd) versus bortezomib and dexamethasone (Vd; median, 18.7 vs 9.4 months; hazard ratio: 0.53; 95% confidence interval [CI]: 0.44-0.65; P<0.0001) (Dimopoulos et al. Lancet Oncol. 2016;17:27−38). Patient-reported outcomes (PROs) were included as exploratory endpoints in the ENDEAVOR study. Here, we present results of a prespecified analysis of health-related quality of life (HR-QoL) in the ENDEAVOR trial. Methods: HR-QoL was assessed by 3 validated instruments: the European Organization of Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30-item questionnaire (QLQ-C30), the EORTC Quality of Life Questionnaire-multiple myeloma specific 20-item module (QLQ-MY20), and the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) "Additional Concerns" neurotoxicity subscale. These instruments were assessed prior to treatment administration on day 1 of cycle 1, and then every 28 days until disease progression, withdrawal of consent, or commencement of other nonstudy anticancer treatment. Due to differing treatment cycle lengths, the PRO assessments coincided across groups every 12 weeks. The primary PRO hypothesis was superiority of Kd over Vd for the Global Health Status/Quality of Life (GHS/QoL) scale of the QLQ-C30. Seven further subscales were prespecified from the QLQ-C30 (fatigue, nausea/vomiting, pain, physical functioning, role functioning) and the QLQ-MY20 (disease symptoms, side effects of treatment). PRO subscales were compared between groups using a restricted maximum likelihood-based mixed model for repeated measures (MMRM). Two sensitivity analyses were performed for the GHS/QoL scale to evaluate the robustness of the MMRM to missing data. Clinical interpretation for the EORTC QLQ-C30 subscales was guided by pre-specifying minimum important differences (MIDs) based on evidence-based guidelines (5 points for the GHS/QoL scale). For the QLQ-MY20 subscales, the standard error of measurement was used as a proxy for the MID. The proportion of patients who had improved (≥5 points) from baseline on the GHS scale was summarized at each coinciding time point. Results: Baseline completion of the QLQ-C30 questionnaire was similar between groups (Kd, 87.7%; Vd, 84.3%). Compliance was high when calculated for all patients expected to provide a questionnaire at each time point (ie, alive and on-study), ranging from 73.1% to 93.9%. Median duration on study treatment was 40 weeks and 27 weeks for Kd and Vd patients, respectively. Using the MMRM model, Kd was associated with statistically significantly higher GHS/QoL scores compared with Vd (p<0.0001). However, the overall treatment difference point estimate of 3.5 (95% CI, 2.0-5.1) did not reach the pre-defined MID. When including the treatment by time interaction (p=0.28) to estimate the treatment difference at timepoints where HR-QoL assessments coincided with day 1 of a cycle, the point estimates increased over time, with the differences at week 60 and 72 reaching clinical significance (5.4 and 5.8, respectively) (Figure). Results from the two sensitivity analyses confirmed findings from the MMRM analysis. Statistically significant benefits were observed in favor of the Kd group for fatigue (P=0.04), pain (P=0.02), side effects (P<0.0001) and NTx subscales (p=0.0002), although these differences did not meet MID thresholds. The proportion of patients reaching a ≥5 point improvement in the GHS scale was numerically higher in the Kd group up to week 48, although the difference between the groups did not reach statistical significance. Conclusions: This analysis of PROs in the ENDEAVOR study demonstrated that Kd was statistically superior to Vd on the QLQ-C30 GHS/QoL scale, with clinically meaningful differences observed at later timepoints but not on average overall. For patients remaining on longer term treatment, the clinical benefits of Kd compared with Vd were associated with better GHS/QOL. Although not meeting MID thresholds, statistically significant benefits were also observed in favor of the Kd group for other aspects of HR-QoL.

Abstract Introduction The current standard to assess chemotherapy tolerability relies on patient self-reporting. However, as the sole mechanism of managing symptom burden, this may be inconsistent and fraught with bias. Mobile wearable health devices have the ability to monitor and aggregate objective activity and sleep data over long periods of time, but have not been systematically used in the oncology clinic. The aim of the study was to assess whether the use of mobile wearable technology establishes patterns of "sleep" and "wake" states in newly diagnosed Multiple Myeloma (NDMM) patients receiving therapy, and whether these patterns differ over time. Methods Patients presenting to the myeloma clinic at Memorial Sloan Kettering Cancer Center (MSKCC) with a new diagnosis of Multiple Myeloma and smart phone or tablet (iOS or Android) compatible with the Garmin Vivofit device were offered to participate in a mobile wearable bio-monitoring study. All eligible participants were required to receive primary chemotherapy treatment at a MSKCC facility. Treatment was determined by physician. NDMM patients were assigned to one of two cohorts (20 in each; Cohort A - patients <65 years; Cohort B - patients ≥ 65 years). Patients were given Garmin Vivofit devices and asked to download a Garmin Vivofit application and Medidata electronic patient reported outcome (ePRO) application on their phone or tablet. Patients were bio-monitored for physical activity and sleep during baseline period (1-7 days prior to chemotherapy initiation) and continuously up to 6 cycles of chemotherapy. Additionally, patients completed mobile ePRO questionnaires [(EORTC - QLQC30 and MY20) and brief pain inventory scales (BPI)] using the Medidata application at baseline and after each induction cycle. Activity, sleep data, and completed ePRO questionnaire data were automatically synced or transferred to Medidata Rave database through Medidata Sensorlink technology. In this abstract, we report initial results on prospective collection of activity measurements. Additional data from the health-related quality of life questionnaires and clinical outcomes will be presented at later date. Results Between February 2017-March 2018, 37 patients (19 males and 18 females) enrolled onto the study, with 20 in cohort A and 17 in cohort B. The mean age was 55 years (range 41-64) for cohort A and 72 years (range 65-82) for cohort B. Treatment regimens included Carfilzomib/Revlimid/Dexamethasone 14(38%), Velcade/Revlimid/Dexamethasone 10(27%), Daratumumab/Carfilzomib Revlimid/Dexamethasone, 7(19%), Cyclophosphamide/Velcade/Dexamethasone 3(8%), Revlimid/Dexamethasone 2(5%), and Velcade/Revlimid/Dexamethasone-Lite 1(3%). Twenty-four patients have completed the trial, and 7 remain active. Six patients came off-study due to the following reasons: lost devices (n=4), intolerable rash during cycle 3 (n=1), and incompletion of baseline activity (n=1). Three patients were excluded for incomplete data sets with no baseline data collection at the time of analysis. Fifteen patients were available for data review including 10 in cohort A and 5 in cohort B. Mean activity for cohort A was 6,437 steps/24 hr period (1,002 - 12,754) versus for cohort B was 3,218.37 steps/24 hr period (387 - 6,155) (p <0.05). In comparing pre- and post-therapy, overall mean activity for cohort A increased from 5,995 to 6,513 steps/24 hr, 8.6% increase (p=0.78), and for cohort B mean activity increased from 2,249 to 3,420 steps/24 hr, a 52% increase (p=0.2140). We assessed short term effects therapy initiation had on activity for NDMM patients by comparing percent changes in activity (steps/24 hrs) from baseline period to cycle 1 period. We found 3 patients had a >100% increase, 1 patient had 50-100% increase, and 11 patients had within +/- 50% change in activity from baseline. Conclusion Electronic mobile wearable device monitoring in symptomatic NDMM patients may be a useful tool to assess a patient's overall wellness and health as they are receiving chemotherapy. For three patients, we were able to capture a dramatic increase in activity after initiation of treatment. Overall activity in the elderly NDMM patients is decreased compared to younger patients. Mobile wearable monitoring may be an even more useful strategy for tracking elderly and unfit patients that are more prone to side effects, where the balance of response versus quality of life is paramount.

New Mutations

We recently shown that high-dose melphalan (HDM) followed by autologous stem cell transplant (ASCT) as first line therapy in young (<66 yrs) multiple myeloma (MM) patients significantly improves progression-free survival (IFM/DFCI 2009 study). However, the impact of alkylating agent melphalan inducing N-alkylpurine-monoadducts forming interstrand crosslinks (ICLs) in surviving myeloma cells remains an important biological question. We here profiled samples from the IFM/DFCI 2009 study, where patients were randomized to RVD+HDM vs RVD alone, to identify genomic changes induced by HDM and observed at relapse. We analyzed paired purified MM cells collected at diagnosis and at relapse from 68 patients using deep (75X) whole genome sequencing. Forty-five patients were treated with RVD only, while 23 patients received RVD followed by HDM. There was no significant difference between the 2 groups in regard to disease characteristics including sex, age, cytogenetic risk, and best response. Median follow-up was similar (29 vs 31 months, respectively), removing longer follow up as a confounding variable. The number of mutations at diagnosis was similar on both arms (7137 [IQR=3742] vs. 7230 [IQR=3702], p value = 0.67). Although mutational load increased in both arms; there was a significantly higher increase in number of mutations and indels in the HDM arm compared to RVD alone (mutations 5686 vs 1745, p=1.4e-5; and indels 467 vs 360, p= 0.02, respectively). Using a model incorporating number of new mutations, depth, and purity, we found that HDM causes a 4.1 fold higher mutation accumulation rate per month than RVD only (158.3 vs 38.3 mutations/ month; p=0.003). Importantly, newly acquired mutations were localized to regions which overlap with transcribed regions, and accumulated at significantly higher rate in the HDM group (p=0.009). In contrast, we did not observe any significant changes in copy number alterations (CNAs) and structural variants, including translocations, between both arms. A significant change in frequency of driver mutations including RAS/RAF, FAM46C, TP53, and DIS3 was not observed at the time of relapse. Clonality level was increased only for KRAS (p=0.054), while all other specific driver genes had similar clonality level at diagnosis and relapse. Interestingly, a significant increase in mutations involving MYO16 and SLC7A8 genes was observed at relapse in both arms, implicating components of the induction regimen (RVD). Investigating the mutational signature utilization in only newly acquired mutations identified 4 signatures: APOBEC, HR Double Strand Repair, clock-like signature, and unknown. k-means clustering analysis of samples based on signature utilization showed four distinct clusters. All patients clustering with high DNA repair signature utilization were in the HDM arm (65% HDM patients), the majority of whom achieved CR or sCR (74%); these patients acquired 8308 (range 3302-19107) new mutations between diagnosis and relapse. None of the RVD only treated patients were in this cluster. The remaining 35% HDM group patients were clustered with RVD samples and showed unknown signature utilization. Furthermore, motif enrichment analysis identified CYWR and ATGAGATV (p < 1e-130) as enriched motifs around the new mutations in HDM compared to RVD cohort. Importantly and as expected, DNA damage repair pathway genes were frequently targeted in the HDM group: 72% HDM samples accumulated DDR gene mutations vs. only 17% in the RVD alone arm (p < 0.001). At the time of relapse, 100% HDM arm patients had at least one DDR gene mutation and 80% had two or more, while only 37% RVD only group had one or more such mutation. Finally, we have reconstructed phylogenetic and evolutionary trajectories based on mutation and copy-number data from samples at diagnosis and relapse. The clonal composition in both arms was similar at diagnosis; however, HDM caused a significant shift to more subclonal mutations at relapse. chromothripsis and chromoplexy events were detected in 30% patients at diagnosis, which remained constant at relapse regardless of treatment. In summary, we describe significant accumulation of mutations following high dose melphalan. This fundamental molecular change in the disease at relapse, suggests the need for reappraisal of the optimal use and sequencing of high dose melphalan in the era of novel agents.

Introduction: Patients with relapsed and refractory multiple myeloma (RRMM) have limited treatment options and experience poor health-related quality of life (HRQoL). Ide-cel, a B-cell maturation antigen (BCMA)-directed chimeric antigen receptor (CAR) T cell therapy, has shown a favorable clinical benefit-risk profile in patients with RRMM in the phase 2, single-arm KarMMa trial (Munshi NC, et al. J Clin Oncol 2020;38:8503). The impact of ide-cel treatment on primary HRQoL domains of interest preselected as most relevant for the treatment and target population (Fatigue, Pain, Cognitive Functioning, Physical Functioning, and Global Health) has been recently described (Delforge M, et al. HemaSphere 2020;4:EP1000). The aim of this analysis was to report the impact of ide-cel treatment on secondary HRQoL domains of interest and health utility scores in patients with RRMM in the KarMMa trial. Methods: Patients enrolled in the KarMMa trial (NCT03361748) had ≥ 3 prior antimyeloma treatment regimens (including an immunomodulatory drug, a proteasome inhibitor, and an anti-CD38 antibody) and were refractory to their last regimen per International Myeloma Working Group criteria. After lymphodepletion, patients received ide-cel at target dose levels of 150, 300 and 450 × 106 CAR+ T cells. HRQoL was assessed by the European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life C30 (QLQ-C30) and Myeloma Module (MY20) questionnaires and the EuroQol 5 dimensions 5 levels (EQ-5D-5L) instrument at screening, baseline, on the day of ide-cel infusion, and throughout the follow-up period at Months 1-6, 9, 12, and 15 post-infusion. For each domain, clinically meaningful changes from baseline were predefined as recommended in the literature. Analyses were performed after the cutoff date, October 16, 2019, and included patients with ≥ 9+1 months of follow-up. Statistical significance was calculated using the 2-sided Wilcoxon signed-rank test (0.05 significance level). EQ-5D-5L utility indices were calculated using the UK value set as the reference country and compared with UK general population data. Results: Of 128/140 patients enrolled in the KarMMa trial who received ide-cel, 95% (EORTC QLQ-C30) and 94% (EORTC QLQ-MY20, EQ-5D-5L) had a baseline and ≥ 1 post-baseline HRQoL assessment and were evaluable for HRQoL. The compliance rate was ≥ 80% for most visits. For EORTC QLQ-C30, patients demonstrated a clinically meaningful improvement in most functioning and symptom subscale scores from baseline to Month 3 through 15, with statistical significance (p < 0.05) reached at various time points for different subscales throughout the follow-up period. For the Role Functioning, Emotional Functioning and Social Functioning subscales, > 40% of patients reported a clinically meaningful improvement from baseline, ~25% had deterioration and ~35% had no change from baseline from Month 2 onward (Figure shows Month 9 results). Stable status was most frequently observed (~60%) on the Nausea/Vomiting, Constipation, Diarrhea, Insomnia, Dyspnea and Appetite Loss, and Financial Difficulties subscales. For EORTC QLQ-MY20, the mean change from baseline on the Future Perspectives subscale demonstrated a clinically meaningful improvement from baseline at Month 2 through 15, with statistical significance (p < 0.05) reached at Month 5. Body Image subscale scores remained stable from baseline through Month 15. The greatest proportion of patients (> 48%) experienced a clinically meaningful improvement from baseline on the Future Perspective subscale. Stable status was most frequently observed (> 59%) for the Body Image subscale. Both EQ-5D-5L index (0.68 vs 0.86) and EQ visual analogue scale (EQ VAS) scores (68 vs 83) were lower for patients treated with ide-cel when compared with UK general population scores. The index and EQ-VAS mean scores became more comparable to the UK data over time, showing a clinically meaningful (although not statistically significant) improvement from baseline beginning at Month 2 (EQ-5D-5L) or 3 (EQ-VAS) through Month 15. In most patients, a clinically meaningful improvement from baseline was observed, increasing from ~43% to ~47% (EQ-5D-5L index score) and ~57% to ~68% (EQ-VAS). Conclusion: These results show that ide-cel treatment brings clinically meaningful quality-of-life benefits to triple-class-exposed patients with RRMM without compromising any HRQoL domains.

Introduction: Belumosudil (KD025) is a novel oral selective rho-associated coiled-coil kinase 2 (ROCK2) inhibitor specifically designed for the treatment of cGVHD, an immune-mediated inflammatory and fibrotic disorder. In a previous dose-finding study (KD025-208, N=54), two-thirds of patients, including those with fibrotic and inflammatory manifestations, achieved a partial or complete response with belumosudil. Herein, we report on the top-line results (6 months after the last patient in) from the pivotal phase 2 trial (ROCKstar [KD025-213], N=132). Methods: This phase 2, open-label, randomized, multicenter study evaluated belumosudil 200 mg QD (n=66) and BID (n=66) in patients with cGVHD who received 2 to 5 prior lines of therapy (LOT). Treatment continued until clinically significant progression of cGVHD. The primary end point was overall response rate (ORR), defined per the 2014 National Institutes of Health Consensus Criteria. Additional end points included duration of response (DOR), Lee Symptom Scale (LSS) score, failure-free survival (FFS), corticosteroid (CS) dose reductions and overall survival. The study was powered such that the lower bound of the 95% confidence interval (CI) excludes 30%, with appropriate multiplicity adjustment. Results: At enrollment, the median age was 56 years, the median time from cGVHD diagnosis to enrollment was 29 months, 67% of patients had severe cGVHD, 52% had ≥4 organs involved, 72% had received ≥3 prior LOT (including ibrutinib [n=46] or ruxolitinib [n=38]) and 73% were refractory to their last LOT. The baseline characteristics of both arms were well balanced. With a median follow-up of 8 months, the ORR (95% CI) with belumosudil 200 mg QD and BID was 73% (60%-83%) and 74% (62%-84%), respectively (Table 1). In patients who previously received ruxolitinib (29%), the ORR with belumosudil 200 mg QD and BID was 65% (41%-85%) and 72% (47%-90%), respectively. In patients who previously received ibrutinib (35%), the ORR with belumosudil 200 mg QD and BID was 73% (50%-89%) and 71% (49%-87%), respectively. High ORRs were seen in all patient subgroups, regardless of length of time from diagnosis to treatment, including those with severe cGVHD, involvement of ≥4 organs and a refractory response to prior LOT (Figure 1). The response rate was similar across all affected organs. The median time to response was 4 weeks. Of responders, 49% have maintained response for ≥20 weeks. The median DOR has not yet been reached. Clinically meaningful improvement (≥7-point reduction) in LSS score on consecutive assessments was observed in 39% and 33% of patients in the QD and BID groups, respectively. Both responders (43%) and nonresponders (17%) experienced a clinically meaningful improvement in LSS score. FFS was 77% (69%-84%) at 6 months. CS and calcineurin inhibitor discontinuations were seen in 18% and 13% of patients, respectively. Belumosudil was well tolerated, with >95% relative dose intensity in 83% of patients. Drug discontinuation occurred in 10% of patients due to possible drug-related adverse events (AEs), 3% due to progression of underlying disease and 12% due to progression of cGVHD. AEs were consistent with those expected in patients with cGVHD receiving CS and other immunosuppressants (Table 2). Common AEs included fatigue (32%), diarrhea (29%), nausea (26%), cough (24%), dyspnea (24%), upper respiratory tract infection (23%), peripheral edema (21%) and headache (20%). At least 1 serious AE occurred in 34% of patients. Twenty-three percent of patients had at least 1 liver-related investigation; the most common was increased gamma-glutamyltransferase (11%), and only 1 patient showed an increase in bilirubin. Eight patients died during the study; 5 due to AEs (1 possibly related to belumosudil) and 3 during long-term follow-up (>28 days after last dose). There were no reports of cytomegalovirus reactivation or infection. Conclusion: Treatment with belumosudil at both doses resulted in high ORRs across key subgroups, meeting the primary end point of this pivotal randomized trial in cGVHD. Responses were durable and clinically meaningful, irrespective of patient and cGVHD characteristics, and were seen in patients who previously received ruxolitinib and ibrutinib. Belumosudil was well tolerated, with limited and manageable AEs. Further studies will evaluate its use earlier in disease management. The 12-month data analysis will be presented at ASH 2020.

Abstract Background: Lenalidomide (LEN) monotherapy has been effective in extending progression free survival (PFS) and after myeloablative AuSCT in patients (pts) with multiple myeloma (MM) (Attal et al. NEJM 2012, McCarthy et al. NEJM 2012,). Elotuzumab (ELO), a humanized IgG1 immunostimulatory monoclonal antibody against signaling lymphocytic activation molecule F7 (SLAMF7), is FDA approved in combination with LEN and dexamethasone (DEX) for treatment of pts with MM who have received 1-3 prior therapies. The objective of this phase 2 trial is to evaluate the efficacy and safety of adding ELO to LEN as maintenance therapy post-myeloablative AuSCT. We report preliminary results of the primary (PFS) and secondary (overall survival and toxicity) endpoints. Patients and Methods: Between 4/15/2015-1/27/2016, 28 evaluable pts were treated on 28 day cycles with ELO, 10 mg/kg iv weekly for cycles 1-2 and q2weeks for cycles 3-6, then 20 mg/kg once monthly for cycles 7+. Pts enrolled after 1/28/2016 (n=27 pts) have received ELO, 10 mg/kg IV weekly for cycles 1-2, and 20 mg/kg on day 1 from cycle 3 until progression. LEN has been dosed at 10 mg/day for cycles 1-3, with a dose increase to 15 mg/day at physician discretion starting with cycle 4, in the absence of non-hematologic toxicity > grade 1 and significant cytopenias (ANC < 1000/mL, platelet count < 100,000/ml). For the 1st 8 weeks, pts <75 yrs receive 28 mg of DEX 3-24 hours pre-infusion, while pts ≥75yrs receive 8mg; pts receive 4-10 mg iv DEX immediately pre-infusion for all cycles. Pts also receive herpes zoster prophylaxis and thromboprophylaxis commensurate with standard recommendations. The primary endpoint of the study is PFS, defined as the time from AuSCT to clinical progression or death (whichever occurs first), or the time of last contact. Secondary objectives include best response, overall survival, incidence of second primary malignancies and adverse event (AE) profile. Total enrollment of 100 pts is planned. Pts will be followed for 48 months after the last patient is enrolled in the trial. Eligible pts had received no more than 2 lines of induction therapy, and were between 60-210 days post-AuSCT. Results: Patients (n=55) have been treated for a median of 14 cycles (2-30). At study entry, 13 pts (24%) had complete response (CR), 27 (49%) had very good partial remission (VGPR), 14 (25%) had partial remission (PR) and 1 (2%) had minor remission (MR). Best response achieved to date on study is CR in 28 pts (51%), VGPR in 23 pts (42%) and PR in 4 pts (7%). For those who have converted to CR on study, median time to CR has been 5 months. Of 14 pts in CR who have been tested for MRD while on study, 13 are negative by flow cytometry (minimum of 2 million cells evaluated; sensitivity 10 -4-10-5). Two of these 13 have converted from VGPR to MRD negativity at 4 and 14 months on study, respectively. With a median follow up of 21 months, 95% of pts (n=52) remain alive. Three pts (all with high risk disease) had disease progression at 4 (del 17p), 9 (t [4;14]), and 13 (gain 1q) months; of these, 2 have died of progressive disease while receiving salvage therapy. One patient, in VGPR, died on study after developing acute cerebral encephalopathy with refractory status epilepticus of unclear etiology. Two pts withdrew for logistical reasons; 2 have been taken off study per physician discretion (prolonged cytopenias (1), drug rash (1)). Grade 3-4 Hematologic AEs (no. of pts) were: neutropenia 35% (16), thrombocytopenia 9% (4), febrile neutropenia 7% (3), and anemia 7% (3). Grade 3-4 non-Hematologic AEs (no. of pts): diarrhea 17% (8), fatigue 17% (8), pneumonia 15% (7), other infections 15% (7), peripheral neuropathy 11% (5), myalgias 9% (4), nausea/vomiting 7% (3), maculopapular rash 4% (2), dizziness 4% (2), edema 2% (1), memory impairment 2% (1). Renal cell carcinoma was diagnosed in 1 patient, 15 months after removal from study for disease progression. Conclusions: Lenalidomide-elotuzumab is a well-tolerated maintenance therapy on which 44% of 55 pts have had improvement in quality of response while on therapy, including 28% who have converted to CR and 24% who have tested MRD negative. The number of pts who have experienced improvement on study may, in fact, be underestimated in this analysis due to elotuzumab interference with measurement on electrophoretic studies. Additional follow up is required to determine if the improved quality of responses translate into improvements in PFS and OS.

Introduction: Patients with myelodysplastic syndromes (MDS) experience severe anemia, which is commonly managed with frequent red blood cell transfusions (RBCT) in patients refractory to erythropoiesis-stimulating agents. At diagnosis, 85% of patients have anemia and 30-50% depend on RBCT. The administration of RBCT itself provides transient relief in anemia-related symptoms. Per protocol, MEDALIST investigators were advised to transfuse for symptoms related to anemia at the investigators' discretion. Hence, cessation or reduction of RBCT may increase anemia-related symptoms and negatively impact health-related quality of life (HRQoL). Luspatercept is a first-in-class erythroid maturation agent providing clinically meaningful reduction in transfusion burden in patients with transfusion-dependent anemia due to Revised International Prognostic Scoring System (IPSS-R)-defined Very low-, Low-, or Intermediate-risk MDS with ring sideroblasts in the phase 3 MEDALIST trial (NCT02631070). However, the impact of luspatercept on patients' HRQoL has not been evaluated. This analysis aimed to evaluate the effect of luspatercept versus placebo on HRQoL of patients treated for MDS from baseline through Week 25 of the MEDALIST study. Methods: Patients received luspatercept or placebo every 3 weeks for 24 weeks, plus best supportive care (BSC), including tailored amounts of RBCT. Effects of luspatercept versus placebo on HRQoL were evaluated as secondary and exploratory endpoints in the MEDALIST study. In the primary analysis, mean change from baseline to Week 25 (clinical assessment visit) in the European Organisation for Research and Treatment of Cancer's core quality of life questionnaire, version 3.0 (EORTC QLQ-C30) and in the QoL assessment in MDS questionnaire (QOL-E) was determined using mixed-effects repeated measures analysis. Clinically meaningful change within each treatment arm was defined as a ≥ 10-point change in patient-reported outcome (PRO) score from baseline for all EORTC QLQ-C30 domains, and ≥ 0.5 standard deviation of the baseline domain score for all QOL-E domains. Differences between luspatercept and placebo were considered clinically meaningful if the change from baseline between treatment arms exceeded the threshold for a clinically meaningful difference. In an exploratory analysis, patient-reported impact of transfusion dependence and overall side effects on their daily life was estimated using the QOL-E instrument. Results: A total of 229 patients were randomized; 153 patients to luspatercept and 76 to placebo. The HRQoL-evaluable population, consisting of patients with ≥ 1 post-baseline HRQoL score, was 149 patients in the luspatercept arm and 76 patients in the placebo arm. Questionnaire compliance rates among patients remaining on treatment were similar between luspatercept and placebo treatment groups at Week 25 (EORTC QLQ-C30, 88.2% vs 79.4% and QOL-E, 72.5% vs 69.7%). At baseline, MEDALIST patients had a clinically meaningfully worse HRQoL compared with the general population in 5 of 15 EORTC QLQ-C30 domains: physical functioning, role functioning, social functioning, fatigue, and dyspnea. Through Week 25, there was no clinically meaningful difference in change from baseline between and within the luspatercept and placebo arms across all EORTC QLQ-C30 (Global health status shown in Figure A) and QOL-E domains. A greater proportion of patients in the luspatercept arm relative to placebo reported improvements in daily life from the impact of transfusion burden (Figure B). Relative to baseline, the proportion of patients reporting a lower impact of transfusion dependence on their daily life was 39% versus 22% in luspatercept versus placebo at Week 25; in contrast, the proportion of patients reporting a higher impact of transfusion dependence on their daily life was 12% versus 22% in luspatercept versus placebo. Impact of treatment side effects on patients was comparable between luspatercept and placebo. Conclusions: Luspatercept with BSC reduced RBCT burden and patient-reported transfusion impact on their daily life, while maintaining other aspects of HRQoL from baseline through Week 25 in the MEDALIST study.

Line Of Therapy

Introduction: The majority of newly diagnosed multiple myeloma (NDMM) patients are currently treated with lenalidomide-based regimens as their first line of therapy. This trend is likely to continue in the coming years. Typically, lenalidomide is administered until disease progression and has significantly contributed to better outcomes in these patients. However, most patients relapse, and prognosis worsens with each relapse. The choice of optimal treatment for patients who relapse while receiving lenalidomide as first line of therapy is unclear. Moreau et al (Blood Cancer J. 9, 38 [2019]) concluded that there is limited data on approved combinations for treating these patients and are restricted by the low number of lenalidomide-refractory patients enrolled in the pivotal trials. Results from the ongoing clinical trials of the combination of carfilzomib and anti-CD38 antibodies were not available at the time of the Moreau et al publication. The aim of this targeted literature review was to include this new data and to summarize currently available evidence on progression-free survival (PFS) for the treatment of RRMM patients who progressed on lenalidomide-based regimens. Methods: A targeted literature review was conducted to identify registrational clinical trials in patients with RRMM reporting PFS outcomes. PubMed, congress proceedings, and product labels were searched between Jan 2014 to July 2020. In addition to PFS, demographic, disease characteristics and treatment history were extracted for the trial populations to contextualize potential variations in study outcomes. The regimens studied in these trials were classified as lenalidomide-based, proteasome inhibitor (PI)-based and pomalidomide-based. Number of prior lines of therapy, prior exposure and refractoriness to lenalidomide and bortezomib were reported. Results: Twelve registrational trials were identified based on the search criteria (Table 1). Most pivotal trials assessing lenalidomide-based regimens (POLLUX, ELOQUENT-II, TOURMALINE-MM1) except the ASPIRE trial excluded patients who were refractory to lenalidomide. Trials evaluating PI-based regimens (e.g., CANDOR) or pomalidomide-based regimens (e.g., OPTIMISMM) included these patients, with more recent studies enrolling a larger proportion. Percentage of lenalidomide-exposed (and lenalidomide refractory) ranged from 40% (32%) in CANDOR to 98% (90%) in ELOQUENT III. These studies also enrolled a larger proportion of patients who were bortezomib-exposed, although most of these patients were at first relapse, with the exception of ELOQUENT III and ICARIA where most patients were at third relapse. Among lenalidomide-refractory patients, the median-PFS (mPFS) observed for the pomalidomide-based regimens ranged from 9.5 to 10.1 months and that observed for PI-based regimens ranged from 4.9 to 25.7 months. PFS in the lenalidomide-refractory subgroup was considerably shorter than in the ITT population. The mPFS for patients receiving carfilzomib/daratumumab/dexamethasone (KDd; CANDOR) and isatuximab/carfilzomib/dexamethasone (IsaKd; IKEMA) was not reached at median follow-up of 16.9 and 20.7 months respectively. While the mPFS for (KDd) for lenalidomide-refractory patients in CANDOR trial was not yet reached at median follow up of 16.9 months; the mPFS of 25.7 months for KDd in the MMY-1001 trial appears to be the longest among the assessed regimens. Conclusion: Patients refractory to lenalidomide have shorter PFS and represent a population with high unmet need. This targeted literature review suggests that the PI-based KDd regimen provides longer PFS compared to other lenalidomide-sparing regimens in lenalidomide-refractory populations. Heterogeneity across trial populations may limit the comparability of these treatments.

Abstract Abstract 2234 Introduction/Background: Immunosuppressive therapy is the best alternative for patients with severe aplastic anemia (SAA) without matched sibling donor or with age > 40 years. Since 1988, an alternative protocol was developed with cyclosporine (CSA) and prednisone (PRED) due to irregularity in distribution of anti-thymocyte globulin (ATG) in Brazil. This study aims to show the results of this treatment on the quality of response, overall survival and development of clonal evolution. Materials and methods: 384 patients diagnosed with SAA (Camitta and Bacigalupo criteria) were evaluable by medical records review from 12/1988 to 12/2008. The immunosuppressive therapy consisted of CSA: 12mg/kg/day BID from day (D)1- D8, then 7mg/kg/day BID until 1 year. After that CSA was progressively tapered (5% each month) and ultimately stopped usually by two years. CSA levels were kept between 200–400ng/ml. PRED: 2mg/kg/day from D1-D14 then 1mg/kg/day from D15- D45. From that day on PRED dose was tapered 20% each week. Sulfamethoxazole-trimethoprim and fluconazole were used for prophylaxis against Pneumocystis jiroveci (P carinni) and fungal diseases, respectively. Treatment response was defined as Table 1. Treatment evaluation was performed at 6 weeks, 3, 6 and 12 months and then yearly. At diagnosis: median age was 21 years (2-75), disease duration 95 days (2-4749), and median number of transfusions were 12 (0-200). Etiology was idiopathic in 78%. In peripheral blood, median hemoglobin was 7.4g/dL, granulocytes 580/uL, platelets 12.000/uL and reticulocyte 0.5% (corrected value). 60% of the patients had not been treated previously. Results: Overall survival was 61% ± 3 with a median follow-up of 7 years (range: 2 months - 23 years). Response to treatment: 51% had some degree of response, with good quality of life and transfusions independent (143 patients with complete response and 53 partial response). 36 patients had no response and there were 96 deaths. Fifty six patients have lost follow-up. Most patients achieved response between 3 and 6 months of therapy. In multivariate analysis the number of neutrophils ≥ 200/uL (p = 0.009), platelets ≥ 12.000/uL (p = 0.018), reticulocyte ≥ 0.5% (p <0.001) and starting treatment after 1997 (p = 0.002) had an impact on overall survival. Patients with 15 or more previous transfusions (p = 0.006) and age ≥ 40 years (p = 0.003) had lower survival. Overall survival was 63% ± 4 and 42% ± 6 for for patients with severe disease and very severe aplastic anemia (p <0.001). The subgroup analysis of patients under 10 years old had similar results. Among patients with response, thirty-four remained dependent of CSA. Cumulative incidence of relapse was 28% ± 4 within a median of 4.4 years. Hypertension, gingival hypertrophy and diabetes mellitus were common, but easily controlled. The rate of clonal evolution among this cohort was 7.81% (16 patients developed Paroxysmal Nocturnal Hemoglobinuria, 9 Myelodysplastic Syndrome and 5 Acute Myeloid Leukemia). Conclusion: This study, with a long follow-up, has demonstrated that the overall survival using CSA and PRED is similar to that reported with ATG therapy. Even patients with partial responses had achieved good quality of life, free from transfusions and infections. Survival was influenced by the neutrophils, platelet counts, reticulocyte, number of transfusions, age at diagnosis, and therapy started after 1997. The incidence of clonal evolution was lower when compared to reported trials with ATG + CSA. Disclosures: Oliveira: Alexion: Speakers Bureau.
