    Abstract: 8039 Background: MagnetisMM-3 (NCT04649359) is an open-label, multicenter, registrational phase 2 study evaluating the efficacy and safety of elranatamab monotherapy in pts with RRMM; pts naïve to BCMA-directed therapies were enrolled in Cohort A. Methods: Eligible pts were refractory to at least 1 PI, 1 IMiD, and 1 anti-CD38 antibody. Pts received SC elranatamab in 28-d cycles with step-up doses of 12 mg on C1D1 and 32 mg on C1D4 followed by 76 mg QW beginning C1D8. Pts treated for 6 cycles and achieving partial response (PR) or better with response persisting ≥2 mo were switched to 76 mg Q2W, 46 and 58 pts are included in the Q2W efficacy and safety analyses, respectively. Results: Overall, 123 pts received elranatamab. Median pt age was 68.0 y (range, 36−89), 63.4% of pts had an ECOG PS ≥1 and median prior lines of therapy was 5.0 (2−22); 96.7% and 42.3% of pts were triple-class- and penta-drug refractory, respectively. At data cutoff (~12 mo after last pt initial dose), the median follow up was 12.8 mo (0.2−22.7); 34.1% of pts remained on treatment. Most common reasons for permanent treatment discontinuation were progressive disease (39.0%) and adverse events (AE; 13.8%). Objective response rate per blinded independent central review (BICR) was 61% (95% CI 51.8−69.6), with 39 (31.7%) pts with complete response (CR) or stringent CR (sCR); very good partial response (VGPR) and PR were achieved in 29 (23.6%) and 7 (5.7%) pts, respectively. MRD-negativity (threshold 10 –5 ) was achieved by 92.0% (n = 23/25) of evaluable pts. Median duration of response (mDOR) has not been reached (95% CI 12.9−NE) and DOR at 12 mo was 74.1% (95% CI 60.5−83.6). In pts with CR/sCR or VGPR, mDOR was not reached by 12 mo; in pts with PR, mDOR was 5.2 mo (95% CI 1.6−NE). There were 46 responders by BICR who switched to Q2W dosing ≥24 wk prior to the data cut-off; among these pts, 80.4% maintained/improved their response ≥24 wk after the switch. Median progression-free and overall survival have not been reached by 12 mo, and the respective rates (95% CI) at 12 mo were 57.1% (47.2−65.9) and 62.0% (52.8−70.0). Most common Grade 3/4 treatment emergent AEs were hematologic; Grade 3/4 non-hematologic events reported in ≥5% of pts were COVID-pneumonia (10.6%), hypokalemia (9.8%), pneumonia (7.3%), sepsis (6.5%), hypertension (6.5%), ALT increased (5.7%), and SARS-COV-2 test positive (5.7%). Among pts who switched to Q2W dosing, the incidence of Grade 3/4 AEs decreased by 〉 10% after the switch. Conclusions: Elranatamab remains efficacious and well tolerated in pts with RRMM after 〉 1 y of follow-up. Updated analysis with a median follow up of ~15 mo, the longest of all phase 2 BCMA-CD3 bispecific antibody studies, including the outcome of pts who switched to the Q2W dosing, will be presented. These results support continued elranatamab development for pts with MM. Clinical trial information: NCT04649359 .

    Abstract: TPS8601 Background: Taletrectinib (AB-106/DS-6051b) is a next-generation, brain-penetrant, ROS1/ NTRK tyrosine kinase inhibitor (TKI) and has shown clinically meaningful effect and safety profile in ROS1+ Non-Small Cell Lung Cancer (NSCLC) patients in phase 1 studies (Fujiwara et al, Oncotarget 2018; 9(34): 23729-23737; Ou et al, JTO Clin Res Rep. 2020 Oct 21;2(1):100108). Taletrectinib has also demonstrated activity against ROS1 G2032R resistance mutation and CNS metastases in the ongoing phase 2 TRUST study (NCT04395677) in China. Also, taletrectinib has shown preliminary efficacy against NTRK positive solid tumors in an ongoing phase 2 study (NCT04617054). Methods: TRUST-II study (NCT04919811) is a phase 2, global, multicenter, open-label, single-arm multi-cohort study evaluating the efficacy and safety of taletrectinib for ROS1 fusion-positive advanced metastatic NSCLC and other solid tumors. Taletrectinib will be given at 600 mg once daily in 21-day cycle. The patients with ROS1 fusions detected by local tests are eligible to enroll with retrospective confirmation by a central laboratory. The study consists of four cohorts: cohort 1: systemic chemotherapy naïve or ≤ one prior line and ROS1 TKI naïve NSCLC (N = 53); cohort 2: previously treated with one ROS1 TKI (crizotinib or entrectinib) and with progression who are either chemotherapy naïve or ≤ one line of platinum and/or pemetrexed based therapy for NSCLC (N = 46); cohort 3: ≤ 2 prior ROS1 TKIs and with progression who are either chemotherapy naïve or ≤ 2 lines of platinum and/or pemetrexed based therapy for NSCLC (N = 10); and cohort 4: systemic chemotherapy naïve or ≤ 2 prior lines of chemotherapy, but ROS1-TKI naïve ROS1 positive solid tumor other than NSCLC (N = 10). The primary endpoint is objective response rate (ORR) (RECIST v1.1) by independent review committee (IRC) assessment for cohorts 1 and 2. Key secondary endpoints include IRC-assessed duration of response, IRC-assessed intra-cranial ORR, progression free survival (PFS), overall survival (OS), and safety. This study is currently recruiting in Japan, Republic of Korea, and USA. Additional accrual is planned in Canada, China, and European Union. Clinical trial information: NCT04919811.

    Abstract: 362 Background: JAK-STAT activity has been associated with malignant cell proliferation and production of proinflammatory cytokines involved in cancer progression. INCB039110 is a potent and selective inhibitor of JAK1. Methods: This was a 2-part phase 1b/2 open-label study evaluating INCB039110 (300 or 400 mg QD) in combination with N and G in pts with advanced or metastatic solid tumors (Part 1 [P1] , dose optimization phase) and pts with advanced or metastatic PC who had not received prior chemotherapy (Part 2 [P2] and 2A [P2A] ). Pts in P2 received the MTD established in P1: INCB039110 (300 mg QD) + N (125 mg/m 2 day [d] 1, 8, 15) + G (1000 mg/m 2 d 1, 8, 15), 28-d cycle. For exploratory purposes, pts in P2A underwent a 7-d induction phase with INCB039110 (200 mg QD) before receiving INCB039110 (200 mg QD) + N (125 mg/m 2 d 1, 8, 15) + G (1000 mg/m 2 d 1, 8, 15). The primary objective was to evaluate safety/tolerability. Results: 55 pts were enrolled (27 P1, 20 P2, and 8 P2A). Most patients had advanced PC (n = 46). Median age was 65 (P1), 67 (P2), and 66 years (P2A). Prior therapy: 67% in P1, 30% in P2, and 0% in P2A. The most common reasons for treatment discontinuation were adverse events (AEs; 41% P1, 20% P2, 38% P2A), disease progression (37% P1, 45% P2, 0% P2A), and study termination by the sponsor (0% P1, 0% P2, 38% P2A). Median treatment durations were 84 d (P1), 121 d (P2), and 47 d (P2A). The most common non-hematologic AEs (all grades) were fatigue (59% P1, 75% P2, 88% P2A), nausea (41% P1, 50% P2, 38% P2A), pyrexia (37% P1, 40% P2, 13% P2A), and peripheral edema (30% P1, 50% P2, 25% P2A), with few grade 3 or 4 non-hematologic AEs. The most common grade 3 or 4 hematologic AEs (laboratory values) were neutropenia (33% P1, 60% P2, 13% P2A), lymphopenia (30% P1, 30% P2, 13% P2A), and leukopenia (30% P1, 45% P2, 0% P2A). The most common serious AEs occurring in ≥ 3 pts were pneumonia (n = 4 P1, n = 2 P2, n = 0 P2A) and anemia (n = 3 P1, n = 2 P2, n = 2 P2A). Among evaluable patients, ORR (all PRs) and DCR were 27% (13/48) and 75% (36/48), respectively. Responses were seen across INCB039110 doses. Conclusions: INCB039110 + N/G showed an acceptable safety profile in pts with advanced PC, with the combination demonstrating clinical activity. Clinical trial information: NCT01858883.

    Abstract: Elranatamab is a humanized B-cell maturation antigen (BCMA)-CD3 bispecific antibody. In the ongoing phase 2 MagnetisMM-3 trial, patients with relapsed or refractory multiple myeloma received subcutaneous elranatamab once weekly after two step-up priming doses. After six cycles, persistent responders switched to biweekly dosing. Results from cohort A, which enrolled patients without prior BCMA-directed therapy ( n  = 123) are reported. The primary endpoint of confirmed objective response rate (ORR) by blinded independent central review was met with an ORR of 61.0% (75/123); 35.0% ≥complete response. Fifty responders switched to biweekly dosing, and 40 (80.0%) improved or maintained their response for ≥6 months. With a median follow-up of 14.7 months, median duration of response, progression-free survival and overall survival (secondary endpoints) have not been reached. Fifteen-month rates were 71.5%, 50.9% and 56.7%, respectively. Common adverse events (any grade; grade 3–4) included infections (69.9%, 39.8%), cytokine release syndrome (57.7%, 0%), anemia (48.8%, 37.4%), and neutropenia (48.8%, 48.8%). With biweekly dosing, grade 3–4 adverse events decreased from 58.6% to 46.6%. Elranatamab induced deep and durable responses with a manageable safety profile. Switching to biweekly dosing may improve long-term safety without compromising efficacy. ClinicalTrials.gov identifier: NCT04649359 .
