Arcellx Announces New Positive Data for Its iMMagine-1 Study in Patients with Relapsed and/or Refractory Multiple Myeloma (Businesswire) - P2 | N=110 | iMMagine-1 (NCT05396885) | Sponsor: Kite, A Gilead Company | "Overall response rate (ORR) was 97% (114/117) with a complete response/stringent complete response (CR/sCR) rate of 68% (79/117) and a very good partial response or higher (>VGPR) rate of 85% (100/117), per International Myeloma Working Group (IMWG) criteria as investigator-assessed. Of those evaluable for minimal residual disease (MRD) testing at the time of this data cut, 93.3% (70/75) achieved MRD negativity at a minimum of 10-5 sensitivity. Six-month progression-free survival (PFS) and overall survival (OS) rates were 91.9% and 96.6%, respectively, and 12-month PFS and OS rates were 78.8% and 95.2%, respectively. Median PFS and median OS have not been reached."

Arcellx Provides First Quarter 2025 Financial Results and Business Highlights (Businesswire) - "...'We are on track to present updated data on all 117 patients dosed in iMMagine-1 at the European Hematology Association meeting on Saturday, June 14, 2025, in Milan. As we accelerate toward becoming a commercial organization with the planned launch of anito-cel in 2026, we added two Board members'....Minimal Residual Disease (MRD) negativity was added as a dual primary endpoint in addition to progression-free survival in the global Phase 3, randomized controlled iMMagine-3 clinical study. The iMMagine-3 study was initiated in the second half of 2024 at approximately 130 study sites across North America, Europe, and the rest of the world."

Dr Bishop on the Rationale for Evaluating Anito-Cel in R/R Myeloma (OncLive) - P1 | N=40 | NCT04155749 | Sponsor: Kite | "...anito-cel was investigated in patients with relapsed/refractory multiple myeloma...the FDA guided the study, notably because the CAR T-cell therapy has a synthetic binder...At a median follow-up of 38.1 months, treatment-emergent adverse effects (TEAEs), the study’s primary objective, included no delayed or non–immune effector cell–neurotoxicity syndrome (ICANS) neurotoxicities occurred, including no observed cases of Parkinsonism, Guilliain-Barré syndrome, or cranial nerve palsies...Early efficacy findings from the study revealed that patients treated with anito-cel achieved an overall response rate of 100%, including 79% of patients achieving a complete response (CR) or stringent CR. Of note, 13% of patients achieved a very good partial response, with 8% demonstrating a partial response. Minimal residual disease negativity at a sensitivity threshold of 10–5 was achieved in 89% of evaluable patients."

Overview of iMMagine-1 Trial: Phase 2 Registrational Study of Anitocabtagene Autoleucel for the Treatment of R/R MM (OncLive) - P2 | N=110 | iMMagine-1 (NCT05396885) | Sponsor: Kite, A Gilead Company | "The iMMagine-1 trial evaluates anitocabtagene autoleucel (anti-BCMA chimeric antigen receptor [CAR] T-cell therapy) in patients with R/R MM...High response rates were observed, even in penta-refractory patients, suggesting durable disease control in a population with limited treatment options; Depth of response correlated with improved progression-free survival, reinforcing the potential of BCMA-targeted CAR T therapy in later-line settings....Toxicities were consistent with prior CAR T therapies, including cytokine release syndrome and neurotoxicity, but were generally manageable; Further follow-up is needed to assess long-term safety and durability of responses."

Prior ASCT May Impact Outcomes of CAR T-Cell Therapy in MM (Cancer Therapy Advisor) - P=NA | N=158 | "Researchers found that MM patients with a history of HDM/ASCT had significantly shorter progression-free survival (PFS) after BCMA-directed CAR T-cell therapy than patients who had not received HDM/ASCT. These findings were presented at the ASH Annual Meeting 2024...The CAR T-cell therapies patients received were idecabtagene vicleucel, ciltacabtagene autoleucel, and anitocabtagene autoleucel...There were no significant differences in response between the groups. The overall response rate was 83% in the transplant recipients and 88% in the patients who had not received a prior transplant (P =.37). Rates of complete response were 40% and 48%, respectively (P =.12)....Similarly, there was no significant difference in overall survival (OS) between the groups. The median OS was 34.2 months in transplant recipients and was not reached in patients who had not received a prior transplant (P =.43). The 18-month OS rates were 49% and 58%, respectively."

Efficacy and Safety of Chimeric Antigen Receptor T-Cell Therapy in Relapsed and Refractory Multiple Myeloma – a Meta-Analysis (ASH 2024) - "We included 7 trials each of Ciltacabtagene autoleucel (cilta-cel) and Idecabtagene vicleucel (ida-cel) while 21 trials used different CAR-T cell therapies including GPRC5D, HDS269B, C-CAR088, HBI0101, CART-ddBCMA, ALLO-715, ARI0002h. This analysis has limitations with significant heterogeneity among studies. There were different CAR T-cell therapies with diverse designs of studies which limit the generalization of results."
