PURPOSE CARTITUDE-1, a phase Ib/II study evaluating the safety and efficacy of ciltacabtagene autoleucel (cilta-cel) in heavily pretreated patients with relapsed/refractory multiple myeloma, yielded early, deep, and durable responses at 12 months. Here, we present updated results 2 years after last patient in (median follow-up [MFU] approximately 28 months), including analyses of high-risk patient subgroups. METHODS Eligible patients had relapsed/refractory multiple myeloma, had received ≥ 3 prior lines of therapy or were double refractory to a proteasome inhibitor and immunomodulatory drug and had received prior proteasome inhibitor, immunomodulatory drug, and anti-CD38 therapy. Patients received a single cilta-cel infusion 5-7 days after lymphodepletion. Responses were assessed by an independent review committee. RESULTS At a MFU of 27.7 months (N = 97), the overall response rate was 97.9% (95% CI, 92.7 to 99.7); 82.5% (95% CI, 73.4 to 89.4) of patients achieved a stringent complete response. Median duration of response was not estimable. Median progression-free survival (PFS) and overall survival (OS) were not reached; 27-month PFS and OS rates were 54.9% (95% CI, 44.0 to 64.6) and 70.4% (95% CI, 60.1 to 78.6), respectively. Overall response rates were high across all subgroups (95.1%-100%). Duration of response, PFS, and/or OS were shorter in patients with high-risk cytogenetics, International Staging System stage III, high tumor burden, or plasmacytomas. The safety profile was manageable with no new cilta-cel–related cytokine release syndrome and one new case of parkinsonism (day 914 after cilta-cel) since the last report. CONCLUSION At approximately 28 months MFU, patients treated with cilta-cel maintained deep and durable responses, observed in both standard and high-risk subgroups. The risk/benefit profile of cilta-cel remained favorable with longer follow-up.

Summary: The multiple myeloma treatment landscape has changed dramatically. This change, paralleled by an increase in scientific knowledge, has resulted in significant improvement in survival. However, heterogeneity remains in clinical outcomes, with a proportion of patients not benefiting from current approaches and continuing to have a poor prognosis. A significant proportion of the variability in outcome can be predicted on the basis of clinical and biochemical parameters and tumor-acquired genetic variants, allowing for risk stratification and a more personalized approach to therapy. This article discusses the principles that can enable the rational and effective development of therapeutic approaches for high-risk multiple myeloma.

Abstract Background Patients with high-risk, newly diagnosed multiple myeloma (HR-NDMM) who are ineligible for autologous stem cell transplant (ASCT) have limited first-line treatment options. Recent meta-analyses evaluating the impact of incorporating daratumumab in the backbone regimen on progression-free survival (PFS) have found mixed results in these patients. Materials and Methods A pooled analysis of patient-level data for ASCT-ineligible patients with HR-NDMM [ie, del(17p), t(4;14), t(14;16)] from the MAIA and ALCYONE trials; stratified by study identifier and adjusting for cytogenetic abnormality subtype, baseline performance status, International Staging System stage, myeloma type, and renal impairment; was conducted. Impact of daratumumab on PFS and rates of complete response or better (≥CR), minimal residual disease (MRD)-negative CR, very good partial response or better (≥VGPR), and overall response (ORR) was compared to control. Results Among 101 patients in the daratumumab and 89 patients in the control cohort, median follow-up was 43.7 months. Daratumumab reduced the risk of progression or death by 41% (adjusted hazard ratio for PFS [95% confidence interval (CI)] = 0.59 [0.41-0.85]) versus control. At 36 months, the estimated proportion of patients who did not progress and were still alive was 41.3% in the daratumumab and 19.9% in the control cohort. Rates of ≥CR (41.6% vs. 22.5%), MRD-negative CR (24.8% vs. 5.6%), ≥VGPR (75.2% vs. 46.1%), and ORR (92.1% vs. 74.2%) were higher for daratumumab versus control. Conclusion These findings demonstrate that incorporation of daratumumab in frontline treatment regimens reduced the risk of progression or death and improved response rates among ASCT-ineligible HR-NDMM patients.

AbstractMajor developments in the treatment of multiple myeloma (MM) over the past decade have led to a continued improvement in survival. Significant progress has been made with deeper and longer remissions seen with newer treatment approaches—both for induction as well as maintenance therapy. The treatment approach to MM is guided by several factors including patient age, frailty, comorbidities, eligibility for autologous stem cell transplantation (ASCT), and risk stratification into standard‐risk or high‐risk MM. High‐risk MM is defined by the presence of t(4;14), t(14;16), t(14;20), del (17p), TP53 mutation, or gain (1q). Transplant eligible patients should receive 4–6 cycles of induction followed by stem cell collection. Patients can then undergo ASCT, or continue induction therapy and shift to maintenance, delaying ASCT till first relapse. Transplant ineligible patients should receive induction therapy followed by maintenance. For induction therapy prior to ASCT, a proteasome inhibitor‐IMiD combination remains standard with monoclonal antibody‐based quadruplets preferred in high‐risk patients. Among transplant ineligible patients, those with standard‐risk MM should receive DRd continued until disease progression, while bortezomib containing regimens (VRd or VRd lite) can be considered for high‐risk patients. Finally, standard‐risk patients should receive lenalidomide maintenance after induction/ASCT, while proteasome inhibitor‐IMiD combinations should be used for high‐risk patients.

Abstract Introduction: Ciltacabtagene autoleucel (cilta-cel), a chimeric antigen receptor T (CAR-T) cell therapy with 2 B-cell maturation antigen (BCMA) targeting single-domain antibodies, demonstrated early, deep, and durable responses in the phase 1b/2 CARTITUDE-1 study in patients (pts) with relapsed/refractory multiple myeloma (RRMM) who had been heavily pretreated (Berdeja, Lancet, 2021). After a median follow-up of 12.4 months, the overall response rate (ORR; as assessed by independent review committee) was 97%, with 67% of pts achieving stringent complete response (sCR). The 12-month progression-free survival (PFS) and overall survival (OS) rates were 77% and 89%, respectively. Here, we report updated results from CARTITUDE-1 with longer duration of follow-up (median 18 months). Methods: Eligible pts had MM and received ≥3 prior therapies or were refractory to a proteasome inhibitor (PI) and an immunomodulatory drug (IMiD), and had received a PI, IMiD, and an anti-CD38 antibody. After apheresis, bridging therapy was permitted. Pts received a single cilta-cel infusion (target dose 0.75×10 6 CAR+ viable T cells/kg; range 0.5-1.0×10 6) 5-7 days (d) after lymphodepletion (300 mg/m 2 cyclophosphamide, 30 mg/m 2 fludarabine daily for 3 d). Primary objectives were to characterize cilta-cel safety, confirm the recommended phase 2 dose (phase 1b), and evaluate cilta-cel efficacy (phase 2). Response was assessed per IMWG criteria by an independent review committee and minimal residual disease (MRD) negativity at 10 -5 by next-generation sequencing. In this combined phase 1b and phase 2 analysis, cytokine release syndrome (CRS; per Lee et al Blood 2014 grading criteria) and neurotoxicity (by CTCAE v5.0) were mapped to the ASTCT criteria for CRS and immune effector cell-associated neurotoxicity (ICANS), respectively. Results: As of Feb 11, 2021, 97 pts (58.8% male; median age 61.0 years [range 43-78]) received cilta-cel. Pts had received a median of 6 (range 3-18) prior lines of therapy; 83.5% were penta-drug exposed, 87.6% were triple-class refractory, 42.3% were penta-drug refractory, and 99.0% were refractory to last line of therapy. ORR was 97.9% (95% CI: 92.7-99.7); 80.4% of pts achieved sCR, and 94.8% achieved very good partial response or better (Figure). The median time to first response was 1 month (range 0.9-10.7), median time to best response was 2.6 months (range 0.9-15.2), and median time to complete response or better was 2.6 months (range 0.9-15.2). The median duration of response was 21.8 months (95% CI: 21.8-not estimable). Of 61 pts evaluable for MRD, 91.8% were MRD negative at the 10 -5 threshold; MRD 10 -5 negativity was sustained for ≥6 months in 44.3% (27/61) of pts and ≥12 months in 18% (11/61) of pts. The 18-month PFS and OS rates were 66.0% (95% CI: 54.9-75.0) and 80.9% (95% CI: 71.4-87.6), respectively. 18-month PFS rates in pts who achieved sustained MRD for ≥6 months and ≥12 months were 96.3% (95% CI: 76.5-99.5) and 100%, respectively. The most common grade 3/4 hematologic AEs in ≥25% of pts were neutropenia (94.8%), anemia (68.0%), leukopenia (60.8%), thrombocytopenia (59.8%), and lymphopenia (49.5%). There were no fatalities related to cytopenias, and no new safety signals with longer follow-up. CRS occurred in 94.8% of pts (mostly grade 1/2); median time to onset was 7 d (range 1-12), and CRS resolved within 14 d in 98.9% of pts. There was no new CAR T-cell neurotoxicity since the previous report. Post cilta-cel infusion, 21 deaths occurred during the study: 0 within first 30 d, 2 within 100 d, and 19 more than 100 d post infusion. Ten deaths were due to disease progression, 6 were treatment-related (as assessed by the investigator), and 5 were due to AEs unrelated to treatment. One patient was retreated with cilta-cel (for progressive disease) and had stable disease (per computerized algorithm) post-retreatment with no incidence of CAR T-cell neurotoxicity. Conclusions: At a longer median follow-up of 18 months, a single cilta-cel infusion led to early, deep, and durable responses in heavily pre-treated pts with MM. Follow-up is ongoing and updated data will be presented. Cilta-cel demonstrated a manageable safety profile with no new safety signals observed with longer follow-up. Further investigations of cilta-cel are ongoing in earlier lines of therapy (CARTITUDE-2 [NCT04133636], CARTITUDE-4 [NCT04181827], and CARTITUDE-5 [NCT04923893]) and in outpatient settings.

Abstract Background: Ciltacabtagene autoleucel (cilta-cel) is a novel chimeric antigen receptor T-cell therapy that is being evaluated in the CARTITUDE-1 trial (NCT03548207) in patients with relapsed or refractory multiple myeloma (RRMM) who are triple-class exposed (to immunomodulatory drugs, proteasome inhibitors, and an anti-CD38 monoclonal antibody). As there is no clear standard of care for this patient population, and due to an absence of direct head-to-head trials evaluating cilta-cel and other relevant treatments, indirect treatment comparisons (ITCs) between cilta-cel and treatments used in current clinical practice, ie, physician's choice of treatment (PCT), have been previously conducted. Meta-analyses were performed to derive single summary effect estimates for overall survival (OS) and progression-free survival (PFS) by pooling ITCs evaluating cilta-cel versus PCT in patients with triple-class exposed RRMM. Methods: ITCs examining the comparative effectiveness of cilta-cel versus PCT on OS and PFS were included. Data on cilta-cel corresponded to the February 2021 data-cut for CARTITUDE-1. Data on PCT was leveraged from the following sources: (i) the Flatiron database, a primarily US community-based multiple myeloma registry, (ii) the long-term follow-up results of three global RRMM daratumumab randomized clinical trials (POLLUX [NCT02076009], CASTOR [NCT02136134], and EQUULEUS [NCT01998971]), (iii) the US-based retrospective MAMMOTH study, and (iv) a representative German patient registry maintained by OncologyInformationService (OIs). In each ITC, the PCT group was comprised of patients who satisfied key eligibility criteria for CARTITUDE-1 and was made comparable to CARTITUDE-1 using inverse probability of treatment weighting. Hence, the ITCs were deemed appropriate to meta-analyze. The meta-analyses used a robust variance estimator to account for the use of CARTITUDE-1 in each pairwise ITC. The main meta-analyses considered all participants treated with cilta-cel in CARTITUDE-1 compared with PCT. Sensitivity analyses considered ITC effect estimates based on all enrolled participants in CARTITUDE-1. Pooled summary effect estimates were presented as hazard ratios (HRs) with the corresponding 95% confidence intervals (CIs). Results: Based on availability of data, the main meta-analyses included four ITCs for OS and three ITCs for PFS. Cilta-cel was associated with a statistically significant improvement in OS (HR: 0.21, 95% CI: 0.13 to 0.34; Figure 1) and PFS (HR: 0.20, 95% CI: 0.07 to 0.63; Figure 2) compared to PCT. Sensitivity analyses including all enrolled participants confirmed the results of the main meta-analyses. Conclusions: In the meta-analyses, cilta-cel demonstrated a significant advantage over PCT in terms of OS and PFS, highlighting its potential as an effective therapy in patients with triple-class exposed RRMM.

Abstract Introduction: Multiple myeloma (MM) is a chronic hematologic malignancy with a high symptom burden that can have a substantial negative impact on patients' (pts) health-related quality of life (HRQoL). The introduction of novel triplet regimens for newly diagnosed MM (NDMM) has extended progression-free survival (PFS) and overall survival (OS); however, adverse events and demanding administration and monitoring schedules have a further negative effect on HRQoL, especially among pts who are transplant ineligible (TIE) due to older age and/or frailty. Optimizing initial treatment is particularly important in older pts, many of whom receive only 1 line of therapy. The phase 3 MAIA trial compared daratumumab, lenalidomide, and dexamethasone (D-Rd) vs lenalidomide and dexamethasone (Rd) in TIE pts with NDMM. At a median follow-up of 28 months, D-Rd significantly prolonged PFS and was associated with faster and sustained clinically meaningful improvements in patient-reported outcomes (PROs) vs Rd. Results of an updated analysis with longer follow-up recently confirmed a significant benefit in OS with D-Rd vs Rd as well as a continued significant PFS benefit and higher rates of complete response or better and very good partial response or better. Here we present an update of the HRQoL analysis with additional follow-up. Methods: MAIA (NCT02252172) is a randomized, open-label, active controlled, multicenter, phase 3 study of TIE pts with NDMM who were randomly assigned 1:1 to receive D-Rd or Rd until disease progression (PD) or unacceptable toxicity. PROs were recorded using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item (EORTC QLQ-C30) and the EQ-5D-5L visual analog scale. EORTC QLQ-C30 has 30 items comprising 5 functional scales (physical, role, emotional, cognitive, and social functioning), 1 global health status (GHS) scale, 3 symptom scales (fatigue, nausea and vomiting, and pain) and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, and financial difficulties). Questionnaires were completed at baseline, on day 1 of cycles 3, 6, 9, and 12 for year 1, and every 6 months thereafter until PD. Analyses were conducted on all pts with a baseline and ≥1 post-baseline PRO assessment. Pts were censored at PD or discontinuation of study treatment. Thresholds for meaningful improvement and worsening were defined a priori based on published literature (≥10-point change). Treatment effect was analyzed using a mixed-effects model for repeated measurements including baseline value, visit, treatment, visit by treatment interaction, and randomization stratification factors as fixed effects and individual subject as random effect. Results: At a median follow-up of 56.2 months, discontinuation rates were lower with D-Rd than Rd (56.8% vs 80.8%). For GHS, physical functioning, fatigue, pain, and dyspnea, PROs that are particularly relevant to pts with MM, a numerically greater proportion of pts achieved a meaningful improvement with D-Rd vs Rd (Table 1). Differences were significant for physical functioning, fatigue, and dyspnea. The proportion of pts achieving a meaningful worsening on therapy was similar in both treatment groups (Table 1). The median time to improvement was numerically shorter with D-Rd vs Rd for physical functioning and pain and with Rd vs D-Rd for GHS and fatigue; differences were not significant (Table 2). The median time to worsening of fatigue was similar between groups, numerically longer for D-Rd vs Rd for GHS, and significantly longer with D-Rd than Rd for physical functioning, pain, and dyspnea (Table 2). Median time to worsening of pain with D-Rd vs Rd was 39.43 vs 17.97 months, reflective of an additional ~21 months without worsening pain among pts treated with D-Rd. Between-group differences for least squares mean change from baseline for these 5 PROs favored D-Rd vs Rd at all assessment time points except cycle 3 for physical functioning and cycle 6 for fatigue; differences were significant at ≥1 timepoint for each scale. Conclusions: These updated PRO analyses from the MAIA study demonstrate sustained and clinically meaningful improvements in HRQoL with D-Rd vs Rd with almost 5 years of follow-up. These results are consistent with the clinical benefits of superior PFS, OS, and deep responses observed with D-Rd compared with Rd and support the use of D-Rd in older pts. Figure 1 Figure 1.

Abstract Introduction: The phase 3 MAIA study (NCT02252172) evaluated the addition of daratumumab (D) to lenalidomide and dexamethasone (Rd) in patients (pts) with transplant-ineligible newly diagnosed multiple myeloma (NDMM). At a median follow-up of 56.2 months, D-Rd prolonged progression-free survival (PFS) and overall survival (OS) versus Rd alone, despite almost half of the pts in the Rd arm who received subsequent therapy receiving a daratumumab-containing regimen as any subsequent line of therapy (Facon T, et al. Presented at: European Hematology Association 2021 Virtual Congress. Abstract LB1901). Approximately 20% to 50% of pts with MM have baseline renal impairment that can affect the choice and efficacy of therapy (Dimopoulos MA, et al. Journal of Clinical Oncology. 2016;34[13]:1544-1557). Here, we report results from MAIA for D-Rd vs Rd in pts with impaired renal function based on lenalidomide starting dose at a median follow-up of 56.2 months. Methods: Pts with NDMM ineligible for high-dose chemotherapy and autologous stem-cell transplantation due to age ≥65 years or comorbidities were randomized 1:1 to receive D-Rd or Rd. Pts in both arms received 28-day cycles of oral Rd (R: 25 mg [10 mg recommended if creatinine clearance (CrCl) was 30-50 mL/min] on Days 1-21; d: 40 mg [20 mg if aged >75 years or body-mass index <18.5 kg/m 2] on Days 1, 8, 15, 22). Pts in the D-Rd arm also received intravenous D (16 mg/kg once weekly for Cycles 1-2, once every 2 weeks for Cycles 3-6, and once every 4 weeks thereafter). Pts in both arms were treated until disease progression or unacceptable safety events. The primary endpoint was PFS, and a secondary endpoint was OS. Renal impairment was defined as a baseline CrCl of ≤60 mL/min. Results: 737 pts were randomized (D-Rd, n=368; Rd, n=369); 162 (44%) pts in the D-Rd arm and 142 (38%) pts in the Rd arm had renal impairment as defined. At a median follow-up of 56.2 months, in pts with renal impairment who received a lenalidomide starting dose of 25 mg (25 mg subgroup; D-Rd, n=60 [37%]; Rd, n=62 [44%]), a PFS and OS advantage was observed with D-Rd versus Rd (Table). In pts with renal impairment who received a lenalidomide starting dose of <25 mg (<25 mg subgroup; D-Rd, n=98 [60%]; Rd, n=75 [53%]), median PFS and OS were prolonged with D-Rd versus Rd (Table). Among pts in the 25 mg subgroup who died (D-Rd, n=12; Rd, n=29), disease progression was the primary cause of death in 6 (50%) pts in the D-Rd arm and 10 (34%) pts in the Rd arm. Among pts in the <25 mg subgroup who died (D-Rd, n=44; Rd, n=37), disease progression was the primary cause of death in 16 (36%) pts in the D-Rd arm and 11 (30%) pts in the Rd arm. Conclusion: After ~5 years of follow-up, D-Rd showed a PFS improvement versus Rd in transplant-ineligible pts with NDMM and renal impairment regardless of lenalidomide starting dose. An OS advantage for D-Rd versus Rd was observed in pts with renal impairment who received a lenalidomide starting dose of 25 mg; in pts with renal impairment who received a lenalidomide starting dose of <25 mg, median OS was prolonged for D-Rd versus Rd, but the OS benefit was less pronounced. Overall, among pts with renal impairment, PFS and OS benefits of D-Rd versus Rd were observed regardless of lenalidomide starting dose; however, dose recommendations per the lenalidomide prescribing information should be followed. Many transplant-ineligible pts with NDMM may not receive a second line of therapy; our results support the frontline use of D-Rd to provide prolonged disease control in transplant-ineligible pts with NDMM and renal impairment.
