Background: SAR442257 (SAR'257) is a trispecific antibody that targets CD38, CD3 and CD28. Simultaneous CD3 and CD28 binding triggers T cell co-signaling, and additional CD38 recognition directs the T cells to CD38+ cancer cells such as multiple myeloma (MM) and non-Hodgkin lymphoma (NHL). This is a first-in-human phase 1 study investigating the safety, efficacy, pharmacokinetic (PK) and pharmacodynamic (PD) profile of SAR'257 in patients (pts) with refractory and relapsed (rr) MM and rrNHL. Methods: This is a multicenter, international, open-label, dose-escalation study (NCT04401020) of SAR'257 in pts with rrMM refractory to standard-of-care (SOC) options, including anti-CD38 monoclonal antibodies, and in pts rrNHL without any SOC options. SAR'257 was administered intravenously with lead-in doses (Day 1−5) in the first week, followed by twice weekly (BIW) or once weekly (QW) dosing; 11 target dose levels (TDLs) in pts with rrMM (9 TDLs: 0.06-11 µg/kg BIW; 2 TDLs: 18-27 µg/kg QW), and 2 TDLs in pts with rrNHL (2 µg/kg BIW and 4 µg/kg QW). Results: As of February 19, 2024, 47 pts (rrMM, n=40; rrNHL, n=7) received SAR'257. The median ages (years) were 64 (rrMM; range: 40−84) and 70 (rrNHL; range: 18−75). The median number of prior lines was 5 (range: 3−12) for rrMM and 5 (range: 2−7) for rrNHL cohort. In rrMM cohort, all (100%) pts had prior exposure to an anti-CD38 monoclonal antibody (MAb) and were refractory to anti-CD38 and in rrNHL cohort all were anti-CD38 naïve. The median time from last anti-CD38 dose was 2.7 (range: 1−65) months for rrMM cohort. Safety analysis revealed that 68% (n=32) pts had treatment-emergent adverse events (TEAEs; 26 pts in rrMM and 6 pts in rrNHL); 21.3% pts (n=10) Grade (G) ≥3 TEAEs (7 in rrMM and 3 in rrNHL). Cytokine release syndrome (CRS) was the most common TEAE, occurring in 52.5% of rrMM pts across all TDLs (n=21; G≥3 in 1 pt from 11 µg/kg BIW TDL) and in 57.1% of rrNHL pts (n=4; no G≥3) at the two TDLs tested. Repetitive CRS episodes (>1 episode) were more frequent at higher TDLs. Infusion-related reactions (IRRs; any G) were observed in 22.5% pts with rrMM (n=9; no G≥3) and in 28.5% pts with rrNHL (n=2; G≥3 in 1 pt). Epstein-Barr virus (EBV) infection/reactivation was reported in 17.5% (n=7; G≥3 in 4 pts) and 28.6% (n=2; no G≥3) pts with rrMM and rrNHL respectively. Further, 15% (n=6, G≥3 in 2 pts) from rrMM and 14.3% (n=1; G2 CMV reactivation) pts from rrNHL cohort reported cytomegalovirus (CMV) infection/reactivation. One case of immune effector cell-associated neurotoxicity syndrome (ICANS) was reported (G4) in the rrNHL cohort. Four dose-limiting toxicities (DLTs) were observed in the rrMM cohort [1 at 4 µg/kg BIW (G3 hepatotoxicity); 1 at 11 µg/kg BIW (G5 CRS−EBV reactivation; and 2 at 27 µg/kg QW (G3 CMV infection reactivation and G3 febrile neutropenia in same pt)]. Three DLTs were observed in the rrNHL cohort (2 at 2 µg/kg BIW [G4 neutropenia and G4 thrombocytopenia; same pt] and 1 at 4 µg/kg QW [ICANS G4]). For pts with rrMM, the maximum plasma concentration of SAR'257 reached within or above the theoretical efficacious range (0.1−1nM; extrapolated from ex vivo models), starting at 8 µg/kg BIW and 18 µg/kg QW in the first treatment cycle. As of July 08, 2024, the overall response rate (ORR), defined as partial response (PR) or better, was 5% (n=2) in the rrMM cohort: 1 pt exhibited stringent complete response (duration of response [DOR]=8.1 months, on-going) and 1 showed a complete response (CR) at 27 µg/kg QW TDL. In rrNHL cohort, the ORR was 14.3%, 1 pt achieved PR (DOR=7.1 months) at 2 µg/kg BIW TDL. The disease control rate (stable disease or better for >8 weeks) was 60% (n=24) and 28.6% (n=2) in the rrMM and rrNHL cohorts respectively. For both cohorts exploratory biomarker analysis revealed that: (1) SAR'257 treatment activated peripheral blood T cells and reduced regulatory T cell numbers and CD4/CD8 ratio; (2) CD38 expression on plasma cells positively corelated with time since the last anti-CD38 MAb dose; (3) Among the pts experiencing CRS, the peak values of cytokines (Interleukin (IL)-6, IL-8, and C-reactive protein) were significantly higher during the first cycle in comparison to subsequent cycles. Conclusion: This Phase 1 study of SAR'257 showed an anti-tumor response in a small number of pts from the rrMM and rrNHL cohorts. Due to safety concerns, in particular high rates of EBV and CMV reactivation and recurrent episodes of CRS in the higher dose levels, the study was terminated during dose escalation.

AbstractObjectivesCluster 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.MethodsThis 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).ResultsThirty‐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.ConclusionsThe 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: Multiple myeloma (MM) is characterized by somatic mutations involving cancer-associated genes. The MyDRUG trial was initiated to explore the efficacy of specific molecularly-targeted therapies in combination with a standard triplet combination in MM. Methods: MyDRUG (NCT03732703) is a genomically-guided umbrella trial for patients with functional high-risk MM, defined as early relapse following primary therapy (3 years for transplant with maintenance, 18 months without), with specific genetic abnormalities. Patients with no actionable mutation or mutations with allelic burden below 30% were randomly assigned to one of the “non-actionable” arms. Here we present the data for the Y3 arm which combines selinexor (60mg po days 1,8,15), ixazomib (4mg po days 1,8,15), pomalidomide (3mg po days 1-21) and dexamethasone (40mg po weekly) (Seli-IPD), given on a 28-day cycle. The primary objective of the Y3 sub-protocol was to evaluate the overall response rate (ORR) according to the International Myeloma Working Group consensus criteria. Secondary objectives included assessment of adverse events (AEs). Results: 17 patients were enrolled into the Y3 arm. The average age was 62 (51-79), 65% were male with a median of 29 months since initial diagnosis and a median of 2 prior lines of therapy. The ORR (> PR) was 52.9% with a clinical benefit rate (> MR) of 58.8%. The median progression free survival was 10.2 months ( 95% CI: 3.9; 12.9) with a median overall survival which has not yet been reached; with all 17 patients still alive at the current data cutoff. No dose-limiting toxicities were seen. Eight patients (47.1%) experienced a serious AE with 2 patients (11.8%) experiencing an AE leading to treatment discontinuation. Two patients (11.8%) required dose reductions. The most common non-hematologic AEs were fatigue, nausea and constipation; all of which were grade 1 and 2. Conclusions: In this platform study of patients with relapsed, functionally high-risk MM, patients who received Seli-IPd exhibited significant efficacy and a manageable AE profile. Furthermore, this provides an all-oral option for patients wishing to minimize their office visits and parenteral therapy administrations.

Background: Maintenance therapy with lenalidomide post-autologous stem cell transplantation (ASCT) has shown to improve progression-free survival (PFS) in multiple myeloma (MM), and has largely become the standard of care. However, toxicity leads to early discontinuation in nearly one-third of patients and additional options are needed (McCarthy, et al, JCO, 2017). Ixazomib is another maintenance option that has been shown to improve PFS; however, studies comparing lenalidomide and ixazomib are lacking. In this randomized phase 2 study, we analyzed the safety and efficacy of using lenalidomide and ixazomib as part of consolidation and maintenance therapies after ASCT (NCT02253316). Methods: Eligible patients, age 18-70 with newly diagnosed MM undergoing ASCT during first-line treatment, were consented prior to ASCT. Approximately 4 months following ASCT, patients received 4 cycles of consolidation therapy with IRd [ixazomib 4 mg on days 1, 8 and 15 of a 28-day cycle, lenalidomide 15 mg on days 1 through 21, and dexamethasone 40 mg on days 1, 8 and 15]. Primary data on IRd consolidation were presented at ASH 2018 (Abstract 109920). One month after the last consolidation cycle, patients were randomized (1:1) to maintenance therapy with single-agent ixazomib (4 mg on days 1, 8 and 15 of a 28-day cycle) or lenalidomide (10 mg daily months 1-3 followed by 15 mg for months 4+). The arms were stratified based on MRD-status post-consolidation. In total, 237 patients were enrolled from 10 US centers. This abstract coincides with planned interim analysis 3 which is the first comparison of ixazomib and lenalidomide maintenance. While the study was not powered to compare PFS between the two arms, the sample will provide a reasonable power to estimate non-inferiority. There is a planned stopping rule for non-inferiority set at a hazard ratio of >1.3 in favor of lenalidomide. Secondary end-points include MRD-negativity following 12 cycles and toxicity. Results: At time of abstract submission, 215 patients had completed IRd consolidation and 191 had begun maintenance. 90 were randomized to ixazomib and 94 to lenalidomide. 7 patients were not randomized due to toxicity during consolidation; data from these patients are not included in the analyses. The characteristics of the two arms are summarized in Table 1. Hematologic toxicity has been infrequent with ixazomib with neutropenia and thrombocytopenia occurring in 11% and 23% of patients. In comparison, neutropenia and thrombocytopenia occurred in 45% and 35% of patients on lenalidomide. The most common non-hematologic toxicities in both arms have been GI-related and infections, both expected events. 16% of patients on ixazomib have experienced Grade 3-4 non-hematologic toxicity compared to 34% on lenalidomide. No grade 3 or higher peripheral neuropathy has been reported in either arm. 11% of patients on ixazomib have discontinued due to toxicity and another 9% have required a dose reduction to 3mg. Lenalidomide toxicity has led to discontinuation in 15% of patients and another 12% were dose reduced to 5mg. Only 45% of patients receiving 4+ cycles of lenalidomide were able to titrate to the 15mg dose. After a median follow-up of 11.2 months from randomization (19.7 months post-ASCT), 30% of patients on ixazomib have discontinued treatment due to disease progression. After a median follow-up of 12.3 months from randomization (20.2 months post-ASCT), 18% patients on lenalidomide have discontinued treatment due to disease progression. Conclusion: Ixazomib and lenalidomide maintenance have been well tolerated to date. A comparison of PFS is currently being conducted as part of interim analysis 3 and final results will be presented, representing the first report directly comparing lenalidomide and ixazomib maintenance.

Abstract Background: Maintenance therapy post-autologous stem cell transplantation (ASCT) has shown to improve progression-free and overall survival in multiple myeloma (MM) and has largely become the standard of care. Consolidation therapy, a brief duration of more-intensive chemotherapy administered prior to maintenance, has been shown to further deepen responses and may improve long-term outcomes. Ixazomib, lenalidomide and dexamethasone (IRd) is an all oral regimen that has been shown to be active in newly diagnosed MM as well as relapsed disease. In this study, we are analyzing the safety and efficacy of IRd as consolidation therapy after ASCT (NCT02253316). Methods: Eligible patients, age 18-70 with newly diagnosed MM undergoing ASCT during first-line treatment, are being consented prior to ASCT. Approximately 4 months following ASCT, patients receive 4 cycles of consolidation therapy with IRd [ixazomib 4 mg on days 1, 8 and 15 of a 28-day cycle, lenalidomide 15 mg on days 1 through 21, and dexamethasone 40 mg on days 1, 8 and 15]. The primary end point is minimal residual disease (MRD) status. MRD is being assessed by ClonoSEQ where possible and by multi-color flow where not. Toxicity, IMWG response rate, PFS, and OS are secondary end points. One month after the last consolidation cycle, patients are randomized (1:1) to maintenance therapy with single-agent ixazomib (4 mg on days 1, 8 and 15) or lenalidomide (15 mg daily). In total, 240 patients will be enrolled on the trial. This presentation coincides with planned interim analysis 2 which included data from the consolidation phase only. Results: As of July 2018, 172 patients with NDMM have been enrolled from 10 centers within the US. The median age was 57 (range 28-70) and 67% were male. 76% were white, 10% African-American/Black, and 13% were another race. 39% were ISS Stage I, 30% were Stage II, and 20% were Stage III. All patients received proteasome inhibitors and/or IMIDs as front-line induction and melphalan as conditioning for ASCT. IRd consolidation started at a median of 110 days post-ASCT (range 80-138). IRd has been well tolerated. Only 4% (6/154) of patients have been unable to complete the 4 cycles of consolidation to date due to toxicity. Grade 3 hematologic toxicity has been uncommon; 4% neutropenia, 3% thrombocytopenia, and 2% anemia. There has been no grade 4 hematologic toxicity. Non-hematologic grade 3-4 toxicities have included: infection (8%), nausea/vomiting/diarrhea (3%), and transaminitis (1%). No grade 3-4 peripheral neuropathy has been reported. One case of grade 5 pneumonia was reported but was not considered related to study treatment. Following ASCT, the MRD-negative rate was 26% and this improved to 37% following consolidation. In the subset of patients with Clonoseq results available, the MRD negative rate improved from 19% to 27%. Clinical response rate improved similarly; prior to consolidation the VGPR or better rate was 76% including 39% CR/sCR. Following consolidation, the VGPR or better rate was 85% including 56% CR/sCR. 137 patients went on to receive maintenance with either ixazomib (n = 71) or lenalidomide (n = 66). At time of submission, the median follow-up from start of IRd is 14 months and 28 patients have relapsed/progressed and 6 have expired. An interim analysis is planned for 2019, representing the first comparison of ixazomib and lenalidomide maintenance. Conclusion: IRd consolidation following ASCT appears to be safe and effective. The all oral regimen is convenient for patients which greatly simplifies follow-up in the peri-transplant period. Study enrollment is scheduled to complete in Q1 of 2019.

Abstract Triplet regimens combining an immunomodulatory agent, a proteasome inhibitor (PI), and a steroid are used to treat newly diagnosed and relapsed multiple myeloma (MM). Although ixazomib (Ix), an oral PI with single agent activity, can be combined with lenalidomide (LEN), patients (pts) with relapsed/refractory (R/R) MM are often LEN-refractory. Pomalidomide (POM) has single agent activity in LEN-refractory disease, and both POM and Ix also show activity in poor cytogenetic risk pts. Methods: Primary objectives: 1) determine the maximum tolerated dose (MTD) of Ix in combination with standard dose POM and dexamethasone (DEX), and 2) evaluate the anti-tumor activity of the triplet. The treatment regimen included two dose levels (3 mg and 4 mg) of Ix on days 1, 8, 15; POM 4 mg days 1-21; and DEX 40 mg days 1, 8, 15, 22, of a 28 day cycle. Eligibility: R/R MM after >1 prior therapy, LEN-refractory, and ≤ grade(gr) 1 peripheral neuropathy (PN). Pts were treated until progression or unacceptable toxicity. Design: Phase I study utilizing a standard 3+3 design; dose limiting toxicities (DLTs) defined during cycle 1. Results: 32 pts treated, 31 evaluable for toxicity and response. Pts received a median 4 cycles (range 1-13); median follow-up is 5.5 months (range 1.8-21.1). Six pts treated on DL1, 25 treated on DL2, the MTD/Phase II dose (P2D). Median age: 62 years (range 38-84); median time from diagnosis: 3.7 years (range 1.0-8.9); median number prior therapies: 3 (range 1-5); prior transplant: n = 23 (74%); double (LEN/Bortezomib[BOR]) or triple (LEN/BOR/Carfilzomib[CFZ]) refractory: 19 (61%). Phase I: DL1 expanded to n=6 after 1/3 pts experienced DLT (gr3 lung infection); no further DLT seen on DL 1 or 2. Adverse events (AEs) related to POM and/or Ix: ANC decrease Gr1/2 n=11 (35%), Gr3/4 n=10 (32%), platelet decrease Gr1/2 n=9 (29%), lymphocyte decrease Gr1/2 n=8 (26%), Gr3/4 n=11 (35%), PN Gr1/2 n=9 (29%), no Gr3/4. Response: Phase I and II, n=31 pts treated. ORR: 45% (6 VGPR, 8 PR); Clinical Benefit Rate (CBR): 81% (6 VGPR, 8 PR, 3 MR, 8 SD). In the pts with high risk cytogenetics (7[23%] 1q, 3[10%] 17p, 2[6%] t(4;14)) an ORR of 58% (3 VGPR, 4 PR) was seen, and the CBR was 83%. In the double or triple refractory pts, an ORR of 26% and CBR of 79% (1 VGPR, 4 PR, 3 MR, 7 SD) were observed. Conclusions: Ix/POM/DEX is a well-tolerated oral combination therapy, and responses were seen even at DL1 and in high risk patients, including those with poor-risk cytogenetics or advanced refractory disease.

As treatment of HIV has improved, people living with HIV (PLWH) have experienced a decreased risk of AIDS and AIDS-defining cancers (non-Hodgkin’s lymphoma, Kaposi sarcoma, and cervical cancer), but the risk of Kaposi sarcoma in PLWH is still elevated about 500-fold compared with the general population in the United States. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for AIDS-Related Kaposi Sarcoma provide diagnosis, treatment, and surveillance recommendations for PLWH who develop limited cutaneous Kaposi sarcoma and for those with advanced cutaneous, oral, visceral, or nodal disease.
