Ciltacabtagene Autoleucel (cilta-cel)


Ciltacabtagene autoleucel (cilta-cel; JNJ-68284528; LCAR-B38M CAR-T cells) is an autologous CAR-T therapy that targets B-Cell Maturation Antigen (BCMA), a molecule expressed on the surface of mature B lymphocytes and malignant plasma cells. The investigational therapy expresses an identical CAR protein as Legend's LCAR-B38M CAR-T product, which was evaluated in a first-in-human clinical study (Legend-2) conducted in multiple sites by Legend Biotech in China.

Phase 1b/2 Study of Ciltacabtagene Autoleucel, a B-Cell Maturation Antigen–Directed Chimeric Antigen Receptor T Cell Therapy, in Relapsed/Refractory Multiple Myeloma

December 02, 2020

As of the May 20, 2020 clinical cutoff, 97 pts (58.8% male; median age 61.0 y [range 43–78]) with R/R MM received cilta-cel (29 in phase 1b; 68 in phase 2). Median follow-up duration was 8.8 mo (range 1.5–20.4). Pts had received a median of 6 prior lines of therapy (range 3–18); 83.5% were penta-exposed, 87.6% were triple-refractory, 41.2% were penta-refractory, and 97.9% were refractory to last line of therapy. Overall response rate per independent review committee (primary endpoint) was 94.8% (95% CI 88.4–98.3), with a stringent complete response rate of 55.7% (95% CI 45.2–65.8), very good partial response rate of 32.0% (95% CI 22.9–42.2), and partial response rate of 7.2% (95% CI 3.0–14.3). All pts achieved a reduction in M-protein. Median time to first response was 1.0 mo (range 0.9–5.8; 80.4% ≤1.0 mo), and median time to complete response or better was 1.8 mo (range 0.9–12.5; 74.1% ≤3.0 mo); responses deepened over time (Figure). Median duration of response was not reached (NR). Of 52 MRD-evaluable pts, 94.2% were MRD-negative at 10-5. The 6-mo progression-free survival (PFS) and overall survival (OS) rates (95% CI) were 87.4% (78.9–92.7) and 93.8% (86.7–97.2), respectively; median PFS and OS were NR. Ten deaths occurred during the study; 8 were due to AEs (both related and unrelated; CRS/hemophagocytic lymphohistiocytosis, neurotoxicity, respiratory failure, sepsis, septic shock, pneumonia, lung abscess, and acute myelogenous leukemia [n=1 each]), and 2 due to progressive disease. AEs reported in >70% of pts were CRS (94.8%; grade [gr] 3/4 4.1%), neutropenia (90.7%; gr 3/4 90.7%), anemia (81.4%; gr 3/4 68.0%), and thrombocytopenia (79.4%; gr 3/4 59.8%). Median time to CRS onset was 7.0 d (range 1–12) and median duration 4.0 d (range 1–27, excluding n=1 with 97 d). CAR-T cell–related neurotoxicity was reported in 20.6% of pts (gr 3/4 10.3%). Cilta-cel CAR+ T cells showed maximum peripheral expansion at 14 d (range 9–43). Among pts with 6 mo’ individual follow-up, 67% had cilta-cel CAR+ T cells below the level of quantification (2 cells/µL) in peripheral blood.
