BACKGROUND: Isatuximab is an anti-CD38 monoclonal antibody approved for the treatment of relapsed or refractory multiple myeloma. Previous analyses of the IKEMA trial showed prolonged progression-free survival in patients with this disease who received isatuximab in combination with carfilzomib-dexamethasone as compared with those who received carfilzomib-dexamethasone alone. Herein, we report the analysis of overall survival from the IKEMA trial. METHODS: This prospective, randomised, open-label, active-controlled, phase 3 study included patients with relapsed or refractory multiple myeloma aged 18 years or older, who had received one to three previous lines of treatment from 69 study centres in 16 countries across North America, South America, Europe, and the Asia-Pacific region. Patients were randomly allocated (3:2) to treatment with either isatuximab plus carfilzomib-dexamethasone (isatuximab group) or carfilzomib-dexamethasone (control group). In the isatuximab group, patients received intravenous isatuximab (10 mg/kg on days 1, 8, 15, and 22 of the first 28-day cycle, and days 1 and 15 of subsequent 28-day cycles). In both treatment groups, intravenous carfilzomib (20 mg/m2 on days 1 and 2 of the first cycle; and 56 mg/m2 on days 8, 9, 15, and 16 of the first cycle, and days 1, 2, 8, 9, 15, and 16 of subsequent cycles) and intravenous or oral dexamethasone (20 mg on days 1, 2, 8, 9, 15, 16, 22, and 23) were administered. The primary endpoint of the trial was progression-free survival, which was reported previously. Treatment continued until progression, unacceptable toxicity, or patient request to discontine. The overall survival analysis reported here was planned to be conducted 3 years after the primary progression-free survival analysis in the intention-to-treat population. Additional analyses were conducted on the secondary endpoints of time to next treatment and second-progression-free survival. Reported p values are non-inferential due to hierarchical testing. This trial is registered with ClinicalTrials.gov (NCT03275285). FINDINGS: Between Nov 15, 2017, and March 21, 2019, 302 patients were enrolled and randomly allocated: 179 (59%) to the isatuximab group and 123 (41%) to the control group. 169 (56%) patients were male, 133 (44%) were female, 214 (71%) were White, 50 (17%) were Asian, nine (3%) were Black or African American, and three (1%) were multiracial. At data cutoff for this overall survival analysis (Feb 7, 2023), 79 (44%) overall survival events in the isatuximab group and 59 (48%) in the control group had occurred (median follow-up 56·61 months [IQR 54·90-58·02]). Median overall survival (in months) was not reached (NR; 95% CI 52·17-NR) in the isatuximab group and was 50·60 months (38·93-NR) in the control group (hazard ratio [HR] 0·855 [95% CI 0·608-1·202], nominal one-sided p=0·18). Survival probability at 48 months was 59·7% (95% CI 52·0-66·7) in the isatuximab group and 52·2% (95% CI 42·7-60·8) in the control group (based on Kaplan-Meier analysis). Improvements in time to next treatment (HR 0·583 [95% CI 0·429-0·792], nominal one-sided p=0·0002) and second-progression-free survival (0·663 [0·491-0·895], nominal one-sided p=0·0035) were observed in the isatuximab group. The most common treatment-emergent adverse events were infusion reactions (82 [46%] patients in the isatuximab group and four [3%] in the control group) and upper respiratory tract infections (71 [40%] and 34 [28%], respectively). Discontinuations due to treatment-emergent adverse events were similar between treatment groups (24 [14%] in the isatuximab group and 22 [18%] in the control group), despite an additional 30 weeks of exposure in the isatuximab group. 12 (7%) patients in the isatuximab group and six (5%) patients in the control group had a treatment-related adverse event with a fatal outcome during study treatment. INTERPRETATION: At the time of the current analysis, a difference in overall survival could not be detected between the treatment groups, and no new safety signals were observed. Collectively, the evidence suggests that isatuximab plus carfilzomib-dexamethasone is a key treatment for patients with relapsed or refractory multiple myeloma. FUNDING: Sanofi.

OBJECTIVES: Cluster of differentiation 38 (CD38) is a key target on multiple myeloma (MM) cells. This multi-centre, Phase 1, single-agent study (NCT04000282) investigated SAR442085, a novel fragment crystallisable (Fc)-modified anti-CD38 monoclonal antibody (mAb), with enhanced affinity towards Fc-gamma receptor on effector cells in patients with relapsed and/or refractory (RR) MM. METHODS: This study comprised two parts: Part-A (dose-escalation involving anti-CD38 mAb pre-treated and naïve patients) and Part-B (dose expansion). Primary endpoints were maximum tolerated dose and recommended Phase 2 dose (RP2D). RESULTS: Thirty-seven heavily pre-treated patients were treated in Part A. Part-B (dose-expansion) was not studied. Seven dose-limiting toxicities were reported at DL3, DL5, DL6, and DL7. RP2D was determined to be 5-7·5 mg/kg. Most common treatment-emergent adverse events were infusion-related reactions in 70·3% (26/37) patients. Grade ≥3 thrombocytopenia was reported in 48·6% (18/37). Overall response rate was 70% in anti-CD38 mAb naïve and 4% in anti-CD38 pre-treated patients, with a median progression-free survival of 7·62 (95%CI: 2·858; not calculable) months and 2·79 (95%CI: 1·150; 4·172) months and, respectively. CONCLUSIONS: The efficacy of SAR442085 was promising in anti-CD38 mAb naïve patients but did not extend to the larger cohort of anti-CD38 mAb pre-treated patients. This observation, along with transient high-grade thrombocytopenia, could potentially limit its clinical use.

BACKGROUND: Bortezomib, lenalidomide, and dexamethasone (VRd) is a preferred first-line treatment option for patients with newly diagnosed multiple myeloma. Whether the addition of the anti-CD38 monoclonal antibody isatuximab to the VRd regimen would reduce the risk of disease progression or death among patients ineligible to undergo transplantation is unclear. METHODS: In an international, open-label, phase 3 trial, we randomly assigned, in a 3:2 ratio, patients 18 to 80 years of age with newly diagnosed multiple myeloma who were ineligible to undergo transplantation to receive either isatuximab plus VRd or VRd alone. The primary efficacy end point was progression-free survival. Key secondary end points included a complete response or better and minimal residual disease (MRD)-negative status in patients with a complete response. RESULTS: A total of 446 patients underwent randomization. At a median follow-up of 59.7 months, the estimated progression-free survival at 60 months was 63.2% in the isatuximab-VRd group, as compared with 45.2% in the VRd group (hazard ratio for disease progression or death, 0.60; 98.5% confidence interval, 0.41 to 0.88; P<0.001). The percentage of patients with a complete response or better was significantly higher in the isatuximab-VRd group than in the VRd group (74.7% vs. 64.1%, P = 0.01), as was the percentage of patients with MRD-negative status and a complete response (55.5% vs. 40.9%, P = 0.003). No new safety signals were observed with the isatuximab-VRd regimen. The incidence of serious adverse events during treatment and the incidence of adverse events leading to discontinuation were similar in the two groups. CONCLUSIONS: Isatuximab-VRd was more effective than VRd as initial therapy in patients 18 to 80 years of age with newly diagnosed multiple myeloma who were ineligible to undergo transplantation.

Longer-term outcomes with the anti-CD38 antibody isatuximab in combination with carfilzomib-dexamethasone (Isa-Kd) were evaluated in the randomized Phase 3 trial IKEMA (NCT03275285), in a prespecified, follow-up analysis of progression-free survival (PFS, primary study endpoint), final complete response (CR) using Hydrashift Isa immunofixation assay, minimal residual disease (MRD) negativity, and safety. Enrolled patients had relapsed/refractory multiple myeloma (1-3 prior treatment lines). Isa 10 mg/kg was administered intravenously weekly in cycle 1 then biweekly. Efficacy analyses were performed in the intent-to-treat population (Isa-Kd: n = 179, Kd: n = 123) and safety evaluated in treated patients (Isa-Kd: n = 177, Kd: n = 122). Consistent with the primary interim analysis, the addition of Isa to Kd prolonged PFS (HR 0.58, 95.4% CI: 0.42-0.79; median PFS 35.7 [95% CI: 25.8-44.0] vs 19.2 [95% CI: 15.8-25.0] months). PFS benefit was observed with Isa-Kd across subgroups, including patients with poor prognosis. The stringent CR/CR rate was 44.1% vs 28.5% (odds-ratio: 2.09, 95% CI: 1.26-3.48), the MRD negativity rate 33.5% vs 15.4% (odds-ratio: 2.78, 95% CI: 1.55-4.99) and the MRD negativity CR rate 26.3% vs 12.2%, with Isa-Kd vs Kd. The safety profile of Isa-Kd was similar to that reported in the prior interim analysis. These findings further support Isa-Kd as a standard-of-care treatment for relapsed multiple myeloma patients.Clinical trial information: ClinicalTrials.gov, NCT03275285.

INTRODUCTION: Melphalan flufenamide (melflufen), a first-in-class alkylating peptide-drug conjugate, plus dexamethasone demonstrated superior progression-free survival (PFS) but directionally different overall survival (OS) favoring pomalidomide (hazard ratio [HR], 1.10) in OCEAN. METHODS: These analyses further investigated prognostic subgroups impacting survival in updated data from the randomized, phase 3 OCEAN study (NCT03151811; date: February 3, 2022) and the phase 2 HORIZON study (NCT02963493; date: February 2, 2022). RESULTS: In OCEAN, subgroups prognostic for OS were age (P = .011; <65 years favored pomalidomide) and no previous autologous stem cell transplant (ASCT) or progression >36 months after ASCT (P = .001; favored melflufen). Overall, 245 of 495 (49%) patients randomized had received a previous ASCT, of which 202 (82%) had progressed within 36 months following their ASCT. When excluding patients who had progressed <36 months post-ASCT (melflufen group, n = 145; pomalidomide group, n = 148), median OS was 23.6 months with melflufen and 19.8 months with pomalidomide (HR, 0.83 [95% CI, 0.62-1.12]; P = .22). Among patients with triple-class refractory disease in HORIZON, patients who had progressed <36 months post-ASCT (n = 58) had a lower response rate and shorter duration of response and PFS than the remaining patients (n = 52). Safety was consistent with previous reports. CONCLUSION: These analyses demonstrate a consistent benefit for melflufen and dexamethasone in patients with relapsed/refractory multiple myeloma who have not received an ASCT or progressed >36 months after receiving an ASCT (ClinicalTrials.gov identifier: NCT03151811).

CONTEXT: Anti-CD38 antibody Isa in combination with Kd is approved in various countries for relapsed multiple myeloma (MM) patients after ≥1 prior therapy based on primary interim analysis (IA) of the Phase 3 IKEMA study (NCT03275285). OBJECTIVE: To report updated efficacy and safety results from IKEMA. Setting and Main Outcome Measures: This prespecified analysis (179 patients randomized to Isa-Kd, 123 to Kd) evaluated progression-free survival (PFS) (primary endpoint) at 159 PFS events, PFS2, minimal residual disease negativity (MRD-) rate, complete response (CR) rate, MRD- and CR rates in all patients, and safety. INTERVENTIONS: Isa 10 mg/kg was given IV weekly for 4 weeks and then every 2 weeks; Kd (20/56 mg/m2, twice weekly, 3/4 weeks) was administered in both arms. RESULTS: At cutoff (14-Jan-2022), with a 44-month median follow-up, 49 (27.4%) patients in Isa-Kd and 11 (8.9%) in Kd were still on treatment. Updated PFS, consistent with IA results, demonstrated significant benefit in favor of Isa-Kd (vs. Kd): HR=0.58 (95.4%CI=0.42-0.79; 35.7 vs. 19.2 months); PFS2 HR=0.68 (95%CI=0.50-0.94; 47.2 vs. 35.6 months). Primary PFS analysis, per FDA request/sensitivity analysis for other countries (censoring PFS events occurring >8 weeks after last valid assessment), was 41.7 versus 20.8 months (HR=0.59, 95%CI=0.42-0.83). With additional follow-up and using Hydrashift Isa immunofixation assay to rule out potential Isa interference in CR determination, final CR rate (Isa-Kd vs. Kd) was 44.1% versus 28.5% (OR=2.09, 95%CI=1.26-3.48); ORR was 86.6% versus 83.7%; MRD- was reached in 33.5% versus 15.4% patients (OR=2.78, 95%CI=1.55-4.99); and the rate of MRD- CR patients was 26.3% versus 12.2% (OR=2.57, 95%CI=1.35-4.88). Safety profiles in both arms remain consistent with prior IKEMA findings. Serious TEAEs were reported in 70.1% of Isa-Kd versus 59.8% Kd patients. The most common any-grade non-hematologic TEAEs in Isa-Kd were infusion reaction (45.8%), diarrhea (39.5%), hypertension (37.9%), and upper respiratory tract infection (37.3%). CONCLUSIONS: These results show unprecedented mPFS, CR, MRD-, and MRD- CR rates in non-lenalidomide containing regimens with benefits maintained through subsequent therapies and a manageable safety profile. Moreover, PFS analysis using FDA censoring rules showed consistent results with the IA. Our findings support Isa-Kd as a standard-of-care treatment for relapsed MM patients.

BACKGROUND: Melphalan flufenamide (melflufen), an alkylating peptide-drug conjugate, plus dexamethasone showed clinical activity and manageable safety in the phase 2 HORIZON study. We aimed to determine whether melflufen plus dexamethasone would provide a progression-free survival benefit compared with pomalidomide plus dexamethasone in patients with previously treated multiple myeloma. METHODS: In this randomised, open-label, head-to-head, phase 3 study (OCEAN), adult patients (aged ≥18 years) were recruited from 108 university hospitals, specialist hospitals, and community-based centres in 21 countries across Europe, North America, and Asia. Eligible patients had an ECOG performance status of 0-2; must have had relapsed or refractory multiple myeloma, refractory to lenalidomide (within 18 months of randomisation) and to the last line of therapy; and have received two to four previous lines of therapy (including lenalidomide and a proteasome inhibitor). Patients were randomly assigned (1:1), stratified by age, number of previous lines of therapy, and International Staging System score, to either 28-day cycles of melflufen and dexamethasone (melflufen group) or pomalidomide and dexamethasone (pomalidomide group). All patients received dexamethasone 40 mg orally on days 1, 8, 15, and 22 of each cycle. In the melflufen group, patients received melflufen 40 mg intravenously over 30 min on day 1 of each cycle and in the pomalidomide group, patients received pomalidomide 4 mg orally daily on days 1 to 21 of each cycle. The primary endpoint was progression-free survival assessed by an independent review committee in the intention-to-treat (ITT) population. Safety was assessed in patients who received at least one dose of study medication. This study is registered with ClinicalTrials.gov, NCT03151811, and is ongoing. FINDINGS: Between June 12, 2017, and Sept 3, 2020, 246 patients were randomly assigned to the melflufen group (median age 68 years [IQR 60-72]; 107 [43%] were female) and 249 to the pomalidomide group (median age 68 years [IQR 61-72]; 109 [44%] were female). 474 patients received at least one dose of study drug (melflufen group n=228; pomalidomide group n=246; safety population). Data cutoff was Feb 3, 2021. Median progression-free survival was 6·8 months (95% CI 5·0-8·5; 165 [67%] of 246 patients had an event) in the melflufen group and 4·9 months (4·2-5·7; 190 [76%] of 249 patients had an event) in the pomalidomide group (hazard ratio [HR] 0·79, [95% CI 0·64-0·98]; p=0·032), at a median follow-up of 15·5 months (IQR 9·4-22·8) in the melflufen group and 16·3 months (10·1-23·2) in the pomalidomide group. Median overall survival was 19·8 months (95% CI 15·1-25·6) at a median follow-up of 19·8 months (IQR 12·0-25·0) in the melflufen group and 25·0 months (95% CI 18·1-31·9) in the pomalidomide group at a median follow-up of 18·6 months (IQR 11·8-23·7; HR 1·10 [95% CI 0·85-1·44]; p=0·47). The most common grade 3 or 4 treatment-emergent adverse events were thrombocytopenia (143 [63%] of 228 in the melflufen group vs 26 [11%] of 246 in the pomalidomide group), neutropenia (123 [54%] vs 102 [41%]), and anaemia (97 [43%] vs 44 [18%]). Serious treatment-emergent adverse events occurred in 95 (42%) patients in the melflufen group and 113 (46%) in the pomalidomide group, the most common of which were pneumonia (13 [6%] vs 21 [9%]), COVID-19 pneumonia (11 [5%] vs nine [4%]), and thrombocytopenia (nine [4%] vs three [1%]). 27 [12%] patients in the melflufen group and 32 [13%] in the pomalidomide group had fatal treatment-emergent adverse events. Fatal treatment-emergent adverse events were considered possibly treatment related in two patients in the melflufen group (one with acute myeloid leukaemia, one with pancytopenia and acute cardiac failure) and four patients in the pomalidomide group (two patients with pneumonia, one with myelodysplastic syndromes, one with COVID-19 pneumonia). INTERPRETATION: Melflufen plus dexamethasone showed superior progression-free survival than pomalidomide plus dexamethasone in patients with relapsed or refractory multiple myeloma.

BACKGROUND: Isatuximab is an anti-CD38 monoclonal antibody approved in combination with pomalidomide-dexamethasone and carfilzomib-dexamethasone for relapsed or refractory multiple myeloma. This phase 3, open-label study compared the efficacy of isatuximab plus carfilzomib-dexamethasone versus carfilzomib-dexamethasone in patients with relapsed multiple myeloma. METHODS: This was a prospective, randomised, open-label, parallel-group, phase 3 study done at 69 study centres in 16 countries across North America, South America, Europe, and the Asia-Pacific region. Patients with relapsed or refractory multiple myeloma aged at least 18 years who had received one to three previous lines of therapy and had measurable serum or urine M-protein were eligible. Patients were randomly assigned (3:2) to isatuximab plus carfilzomib-dexamethasone (isatuximab group) or carfilzomib-dexamethasone (control group). Patients in the isatuximab group received isatuximab 10 mg/kg intravenously weekly for the first 4 weeks, then every 2 weeks. Both groups received the approved schedule of intravenous carfilzomib and oral or intravenous dexamethasone. Treatment continued until progression or unacceptable toxicity. The primary endpoint was progression-free survival and was assessed in the intention-to-treat population according to assigned treatment. Safety was assessed in all patients who received at least one dose according to treatment received. The study is registered at ClinicalTrials.gov, NCT03275285. FINDINGS: Between Nov 15, 2017, and March 21, 2019, 302 patients with a median of two previous lines of therapy were enrolled. 179 were randomly assigned to the isatuximab group and 123 to the control group. Median progression-free survival was not reached in the isatuximab group compared with 19·15 months (95% CI 15·77-not reached) in the control group, with a hazard ratio of 0·53 (99% CI 0·32-0·89; one-sided p=0·0007). Treatment-emergent adverse events (TEAEs) of grade 3 or worse occurred in 136 (77%) of 177 patients in the isatuximab group versus 82 (67%) of 122 in the control group, serious TEAEs occurred in 105 (59%) versus 70 (57%) patients, and TEAEs led to discontinuation in 15 (8%) versus 17 (14%) patients. Fatal TEAEs during study treatment occurred in six (3%) versus four (3%) patients. INTERPRETATION: The addition of isatuximab to carfilzomib-dexamethasone significantly improves progression-free survival and depth of response in patients with relapsed multiple myeloma, representing a new standard of care for this patient population.

In this review, two types of soft-tissue involvement in multiple myeloma are defined: (i) extramedullary (EMD) with haematogenous spread involving only soft tissues and (ii) paraskeletal (PS) with tumour masses arising from skeletal lesions. The incidence of EMD and PS plasmacytomas at diagnosis ranges from 1·7% to 4·5% and 7% to 34·4% respectively. EMD disease is often associated with high-risk cytogenetics, resistance to therapy and worse prognosis than in PS involvement. In patients with PS involvement a proteasome inhibitor-based regimen may be the best option followed by autologous stem cell transplantation (ASCT) in transplant eligible patients. In patients with EMD disease who are not eligible for ASCT, a proteasome inhibitor-based regimen such as lenalidomide-bortezomib-dexamethasone (RVD) may be the best option, while for those eligible for high-dose therapy a myeloma/lymphoma-like regimen such as bortezomib, thalidomide and dexamethasone (VTD)-RVD/cisplatin, doxorubicin, cyclophosphamide and etoposide (PACE) followed by SCT should be considered. In both EMD and PS disease at relapse many strategies have been tried, but this remains a high-unmet need population.
