Abstract In the ALCYONE trial, daratumumab plus bortezomib, melphalan, and prednisone (D-VMP) reduced the risk of disease progression or death by 50% versus bortezomib, melphalan, and prednisone (VMP) in patients with transplant-ineligible newly diagnosed multiple myeloma. Here, we report a subanalysis of East Asian patients from ALCYONE. After a median follow-up of 17.1 and 15.9 months for Japanese (n = 50) and Korean (n = 41) patients, respectively, median progression-free survival for D-VMP versus VMP was not reached (NR) versus 20.7 months in Japanese patients and NR versus 14.0 months in Korean patients. The overall response rate for D-VMP versus VMP was 96% versus 92% in Japanese patients and 91% versus 61% in Korean patients. Using next-generation sequencing, minimal residual disease negativity at 10−5 sensitivity for D-VMP versus VMP was 33% versus 8% among Japanese patients and 17% versus 0% among Korean patients. Rates of any grade and grade 3/4 pneumonia were consistent with the rates observed for the global safety population. Similar efficacy and safety findings were observed in the combined Japanese and Korean subgroup and ≥ 75 years of age subgroup. In conclusion, D-VMP was safe and efficacious in East Asian patients, consistent with the global ALCYONE population.

e20015 Background: The Phase 3 IKEMA study (NCT03275285) demonstrated that isatuximab (Isa) plus carfilzomib and dexamethasone (Kd) significantly improved progression-free survival (PFS) compared with Kd in patients (pts) with relapsed multiple myeloma (RMM) (hazard ratio [HR] 0.53; 99% confidence interval [CI] 0.32–0.89; P= 0.0007). We evaluated the efficacy and safety of Isa-Kd in the East Asian patients (19 Japanese, 27 Korean). Methods: RMM pts who received 1-3 prior lines of therapy were stratified to receive Isa-Kd or Kd. Isa-Kd arm received Isa (10 mg/kg intravenously) weekly for 4 weeks, then every 2 weeks. Both arms received K (20 mg/m2 days 1-2, 56 mg/m2 thereafter) twice-weekly for 3 of 4 weeks, and d (20 mg) twice-weekly. Treatment continued until disease progression or unacceptable adverse events (AE). The primary endpoint was prolongation of PFS. Key secondary endpoints included; very good partial response or better (≥VGPR), complete response (CR) rate and minimal residual disease negativity (MRD–) rate. Results: East Asian pts (25 Isa-Kd, 21 Kd) were randomized. Pt characteristics were similar in the East Asian subgroup compared with the intent to treat (ITT) population (N = 302). Median age (Isa-Kd 64.0 [range 45–83] years vs Kd 60.0 [range 33–73] years); median prior lines Isa-Kd 2.0 (range 1–3) vs Kd 1.0 (range 1–3); refractory to lenalidomide 16.0% Isa-Kd vs 47.6% Kd; refractory to PI 20.0% Isa-Kd vs 33.3% Kd; high-risk cytogenetics 48.0% Isa-Kd vs 42.9% Kd. After a median follow-up of 20.7 months, the addition of Isa to Kd improved ≥VGPR, CR and MRD– rates (Table). The HR 0.64 (95%CI: 0.231-1.764) for disease progression or death favored Isa-Kd. Grade ≥3 AEs were observed in 79.2% Isa-Kd vs 55.0% Kd pts, serious TEAEs in 45.8% Isa-Kd vs 50.0% Kd; TEAEs leading to treatment discontinuation were lower in the Isa-Kd group (4.2% Isa-Kd vs 10.0% Kd). Overall, 64.0% Isa-Kd vs 42.9% Kd pts were still receiving treatment. Conclusions: Efficacy and safety results of Isa-Kd in East Asian pts are consistent with the results of the overall IKEMA population, in which significantly better efficacy (PFS, CR, ≥VGPR and MRD– rate) was reported in favor of Isa-Kd without an increase in the number of patients with serious TEAEs or discontinuations. Isa-Kd is a potential treatment option for East Asian pts with RMM. Clinical trial information: NCT03275285. [Table: see text]

AbstractThe phase 3 COLUMBA study demonstrated noninferiority of subcutaneous daratumumab (DARA SC) to intravenous daratumumab (DARA IV) in relapsed or refractory multiple myeloma. We present a subgroup analysis of Asian patients from COLUMBA. Eligible patients had ≥ 3 prior lines of therapy, including a proteasome inhibitor and an immunomodulatory drug, or were double refractory. Co-primary endpoints were overall response rate (ORR) and maximum trough concentration (Ctrough). Secondary endpoints included rates of infusion-related reactions, progression-free survival, and patient-reported satisfaction with therapy. Sixty-seven Asian patients (DARA SC, n = 30; DARA IV, n = 37) were randomized, including 42 Japanese patients (DARA SC, n = 18; DARA IV, n = 24). Comparable ORRs for DARA SC versus DARA IV were seen in the Asian cohort (66.7% vs 43.2%) and Japanese-only cohort (61.1% vs 54.2%), including patients weighing ≤ 65 kg. Similarity of Ctrough was seen in both Asian and Japanese-only cohorts; the ratio of the geometric mean of the Ctrough concentrations for DARA SC/DARA IV was 143.96% (90% confidence interval (CI), 112.03–185.00%) and 148.02% (90% CI, 113.32–193.34%), respectively. The Asian cohort (both treatment groups) and Japanese-only cohort (DARA SC group) experienced higher rates of grade 3/4 cytopenias compared with the global COLUMBA population, occurring predominantly in patients of low bodyweight; no patients discontinued treatment due to cytopenias. The Cancer Therapy Satisfaction Questionnaire results generally favored DARA SC. In the Asian and Japanese-only cohorts, DARA SC was comparable to DARA IV. The efficacy, pharmacokinetic, safety, and satisfaction results were generally consistent with the global COLUMBA population regardless of patient bodyweight.

TPS8553 Background: The intravenous (IV) formulation of daratumumab (DARA), a human CD38-targeted monoclonal antibody, is approved in many countries for use as monotherapy in relapsed/refractory multiple myeloma (RRMM) and in combination with standard-of-care regimens in RRMM or newly diagnosed MM. A subcutaneous (SC) formulation of DARA is under investigation in several ongoing studies. In the phase 3 COLUMBA study, DARA SC was shown to be non-inferior to DARA IV, demonstrating similar efficacy and pharmacokinetics, with a significantly decreased rate of infusion-related reactions and reduced administration time. The phase 2 LYNX (MMY2065) study will evaluate the efficacy and safety of retreatment with DARA. Methods: In this ongoing, multicenter, open-label, randomized phase 2 study, ~230 patients (pts) with prior exposure to DARA will be randomized 1:1 to receive carfilzomib and dexamethasone (Kd) ± DARA. Pts must have received 1 to 2 prior lines of therapy (at least one of which included DARA IV), with DARA-based therapy completed ≥3 months prior to randomization. Eligible pts have achieved a partial response or better (IMWG criteria) to DARA-based therapy, with a duration of response of ≥4 months. Pts must not have discontinued DARA due to a related adverse event or received prior treatment with carfilzomib. Pts will receive 20 mg/m2 carfilzomib IV on Day 1 of Cycle 1, escalated to 70 mg/m2 on Days 8 and 15; carfilzomib 70 mg/m2 will be administered on Days 1, 8, and 15 of each 28-day cycle thereafter. Dexamethasone 40 mg will be administered (IV or PO) QW for Cycles 1-9 and then on Days 1, 8 and 15 from Cycle 10 onwards. Pts in the D-Kd group will also receive DARA SC (1,800 mg co-formulated with recombinant human hyaluronidase PH20 [rHuPH20; Halozyme]) QW in Cycles 1-2, Q2W in Cycles 3-6, and Q4W thereafter. The primary endpoint is the rate of pts achieving a very good partial response or better. Secondary endpoints include overall response rate, rate of pts achieving complete response or better, progression-free survival, overall survival, overall minimal residual disease-negativity rate, time to next treatment, pharmacokinetics, and safety. Clinical trial information: NCT03871829 .

8026 Background: A prespecified interim efficacy analysis of the Phase 3 IKEMA study (NCT03275285) demonstrated that isatuximab (Isa) plus carfilzomib (K) and dexamethasone (d) (Isa-Kd) significantly improved progression-free survival (PFS) compared with Kd in patients (pts) with relapsed multiple myeloma (RMM) (HR 0.531; 99% CI, 0.318–0.889; P=0.0007), with a clinically meaningful increase in minimal residual disease negativity (MRD-) (29.6% vs 13.0%) and complete response (CR) (39.7% vs 27.6%) rates, and a manageable safety profile. This subgroup analysis of IKEMA examined efficacy and safety in pts aged <70 and ≥70 years. Methods: Pts with 1–3 prior lines of therapy were randomized 3:2 to receive Isa-Kd (n=179) or Kd (n=123). The primary end point was PFS, as assessed by an independent response committee. We compared outcomes in pts <70 vs ≥70 years; division into different or additional age groups resulted in smaller sample sizes. Results: Of the 302 randomized pts, 71.5% were aged <70 years (Isa-Kd: 70.9%; Kd: 72.4%) and 28.5% were aged ≥70 years (Isa-Kd: 29.1%; Kd: 27.6%). Consistent with the significant improvement of PFS in the overall population, the addition of Isa to Kd resulted in improved PFS independently of age (Table). The CR, ≥very good partial response (VGPR), and MRD- rates were higher with Isa-Kd vs Kd. Within the Isa-Kd arm, CR rate and ≥VGPR rate were similar in elderly and younger pts. MRD- was observed in 32.3% of younger pts and 23.1% of elderly pts with Isa-Kd. In both arms, Grade ≥3 and serious treatment-emergent adverse events (TEAEs) were more frequently reported in elderly pts vs pts <70 years old (Table). For both age groups, the incidence of Grade ≥3 TEAEs was higher whereas the incidence of serious TEAEs was similar between Isa-Kd and Kd. In the elderly subgroup, 3 (5.9%) pts receiving Isa-Kd and 1 (2.9%) receiving Kd had fatal TEAEs (Isa-Kd, infection; Kd, general health deterioration due to progressive disease). The most common Grade ≥3 TEAEs in pts aged <70 and ≥70 years treated with Isa-Kd vs Kd were hypertension (18.3% vs 17.0% [<70 years] and 25.5% vs 26.5% [≥70 years]) and pneumonia (14.3% vs 9.1% [<70 years] and 21.6% vs 20.6% [≥70 years]). Conclusions: The addition of Isa to Kd improved PFS and quality of response in elderly pts, with a manageable safety profile, consistent with the benefit observed in the overall IKEMA study population. Isa-Kd provides a potential new treatment option for elderly pts with RMM. Funding: Sanofi. Clinical trial information: NCT03275285. [Table: see text]

Abstract Lenalidomide, bortezomib, and dexamethasone (RVd) followed by autologous stem cell transplantation (ASCT) is standard frontline therapy for transplant-eligible patients with newly diagnosed multiple myeloma (NDMM). The addition of daratumumab (D) to RVd (D-RVd) in transplant-eligible NDMM patients was evaluated. Patients (N = 207) were randomized 1:1 to D-RVd or RVd induction (4 cycles), ASCT, D-RVd or RVd consolidation (2 cycles), and lenalidomide or lenalidomide plus D maintenance (26 cycles). The primary end point, stringent complete response (sCR) rate by the end of post-ASCT consolidation, favored D-RVd vs RVd (42.4% vs 32.0%; odds ratio, 1.57; 95% confidence interval, 0.87-2.82; 1-sided P = .068) and met the prespecified 1-sided α of 0.10. With longer follow-up (median, 22.1 months), responses deepened; sCR rates improved for D-RVd vs RVd (62.6% vs 45.4%; P = .0177), as did minimal residual disease (MRD) negativity (10−5 threshold) rates in the intent-to-treat population (51.0% vs 20.4%; P &lt; .0001). Four patients (3.8%) in the D-RVd group and 7 patients (6.8%) in the RVd group progressed; respective 24-month progression-free survival rates were 95.8% and 89.8%. Grade 3/4 hematologic adverse events were more common with D-RVd. More infections occurred with D-RVd, but grade 3/4 infection rates were similar. Median CD34+ cell yield was 8.2 × 106/kg for D-RVd and 9.4 × 106/kg for RVd, although plerixafor use was more common with D-RVd. Median times to neutrophil and platelet engraftment were comparable. Daratumumab with RVd induction and consolidation improved depth of response in patients with transplant-eligible NDMM, with no new safety concerns. This trial was registered at www.clinicaltrials.gov as #NCT02874742.

ObjectiveThe recent phase 3 trial AGO-OVAR16 demonstrated that pazopanib maintenance improved median progression-free survival in patients with ovarian cancer whose disease did not progress during first-line treatment. However, this improvement was not seen in the subset of East Asian patients. The current analysis evaluated the efficacy and safety of pazopanib maintenance in East Asian patients from AGO-OVAR16 and a separate East Asian study.Materials and MethodsEast Asian patients from AGO-OVAR16 (n = 209) and the East Asian study (N = 145) were randomized 1:1 to receive pazopanib 800 mg/d or placebo for up to 24 months. The primary end point for each study was progression-free survival by RECIST (Response Evaluation Criteria in Solid Tumors) based on investigator assessment. Clinical and genetics data were analyzed separately by study or pooled according to separate predetermined statistical plans.ResultsPazopanib maintenance had a detrimental effect on median progression-free survival versus placebo in East Asian patients from the combined studies (n = 354; 17.9 vs 21.5 months; hazard ratio, 1.114; 95% confidence interval, 0.818–1.518; P = 0.4928). Pazopanib maintenance showed a disadvantage in overall survival in East Asian patients from AGO-OVAR16 versus placebo (hazard ratio, 1.706; 95% confidence interval, 1.010–2.883; P = 0.0465); overall survival analysis was not performed in the East Asian study because of insufficient event numbers. Pazopanib-treated patients had a significantly higher incidence of grade 3 or higher hypertension (27%) and neutropenia (13%) versus placebo.ConclusionsThe treatment effect of maintenance pazopanib in East Asian patients seemed to differ from that in non-Asian patients. In study-specific and pooled analyses, none of the potential factors analyzed could satisfactorily explain the different efficacy results of pazopanib in East Asian patients.

Abstract The phase 3 CLARION study compared carfilzomib-melphalan-prednisone (KMP) with bortezomib-melphalan-prednisone (VMP) in transplant-ineligible newly diagnosed multiple myeloma (NDMM) patients. Patients were randomized 1:1 to KMP or VMP for nine 42-day cycles (C). Patients received carfilzomib on days (D) 1, 2, 8, 9, 22, 23, 29, 30 (20 mg/m2: C1D1, C1D2; 36 mg/m2 thereafter) or bortezomib on D1, 4, 8, 11, 22, 25, 29, 32 (1.3 mg/m2; D4, 11, 25, 32 omitted for C5-9). Melphalan (9 mg/m2) and prednisone (60 mg/m2) were administered on D1-4. The primary endpoint was progression-free survival (PFS). Nine hundred fifty-five patients were randomized (intention-to-treat population: KMP, n = 478; VMP, n = 477). Median PFS was 22.3 months with KMP vs 22.1 months with VMP (hazard ratio [HR], 0.906; 95% confidence interval [CI], 0.746-1.101; P = .159). Median overall survival was similar and not reached in either group (HR, 1.08; 95% CI, 0.82-1.43). Overall response rate was 84.3% for KMP and 78.8% for VMP. Complete response rate was 25.9% for KMP and 23.1% for VMP. Minimal residual disease–negative rates were 15.7% (KMP) and 15.5% (VMP). Adverse events (AEs) of interest (any grade) occurring with a ≥5% higher patient incidence in the KMP arm were acute renal failure (13.9% [KMP] vs 6.2% [VMP]) and cardiac failure (10.8% vs 4.3%). Grade ≥3 AE rates were 74.7% (KMP) and 76.2% (VMP). Grade ≥2 peripheral neuropathy was lower for KMP vs VMP (2.5% vs 35.1%). Treatment with KMP in CLARION did not yield a statistically significant difference in PFS vs VMP. This trial was registered at www.clinicaltrials.gov as #NCT01818752.
