Overview of iMMagine-1 Trial: Phase 2 Registrational Study of Anitocabtagene Autoleucel for the Treatment of R/R MM
Panelists discuss how the preliminary results from the iMMagine-1 trial of anitocabtagene autoleucel in relapsed/refractory multiple myeloma (R/R MM) highlight promising efficacy in triple-class and penta-class refractory patients, potentially reshaping treatment strategies and challenging existing paradigms in managing heavily pretreated myeloma.

IMMagine-1 Phase 2 Study of Anitocabtagene Autoleucel in R/R MM
Background & Objective:
The iMMagine-1 trial evaluates anitocabtagene autoleucel (anti-BCMA chimeric antigen receptor [CAR] T-cell therapy) in patients with R/R MM. Preliminary results focus on efficacy and safety in heavily pretreated patients, including those refractory to triple-class (proteasome inhibitors, immunomodulatory agents, and anti-CD38 monoclonal antibodies) and penta-class therapies.
Preliminary Efficacy:
- 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.
Safety Profile:
- 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.
Clinical Implications:
- Impact on Treatment Strategies:
- The efficacy in triple- and penta-refractory patients may shift treatment paradigms, positioning BCMA-targeted CAR T therapy earlier in the disease course.
- Potential integration into sequencing strategies for R/R MM, especially in those failing standard regimens
- Challenging Existing Paradigms:
- These results reinforce the role of CAR T therapies in overcoming resistance mechanisms in heavily pretreated myeloma.
- The durability of response may challenge the reliance on continuous therapy models, offering the possibility of fixed-duration treatment with sustained benefit.
- Future Directions:
- Optimization of patient selection and bridging strategies
- Comparative studies with bispecific antibodies and other emerging BCMA-directed therapies
These findings highlight anitocabtagene autoleucel as a promising therapeutic option in the evolving R/R MM landscape, warranting continued investigation in larger cohorts.
