Outcomes from the CARTITUDE-1 Study Assessing CAR T-Cell Therapy in Relapsed Refractory Multiple Myeloma

What is the purpose of this study?

CARTITUDE-1 consists of a phase Ib/II portion. The primary objective of the phase Ib was to characterize its safety and confirm the recommended phase II dose, as inferred by the LEGEND-2 study, but in a slightly different population. The primary objective of the phase II portion is to evaluate its efficacy. CARTITUDE-1 used JNJ4528, which now has a name, ciltacabtagene autoleucel or cilta-cel. It’s a structurally distinct second-generation chimeric antigen receptor (CAR) T-cell therapy with two BCMA-binding domains.

Dr. Deepu Madduri presented the updated phase Ib data alongside with the initial phase II data from the CARTITUDE-1 trial.

Results:

Some of the takeaways from cilta-cel is that it had a manageable safety profile, with 95% of the patients having grade 1 and 2 cytokine release syndrome (CRS). CRS is a very known complication of CAR T-cell therapy. And most of the patients had grade 1 and 2 CRS with very little grade 3 or higher CRS. Another complication that’s known with CAR T-cell therapy is neurotoxicity. We saw about 21% having all-grade neurotoxicity, with about 10% having grade 3 or higher.

Conclusion:

A single low-dose infusion of ciltacabtagene autoleucel (cilta-cel), an autologous chimeric antigen receptor (CAR) T-cell therapy, was safe and associated with early, deep, and durable responses in patients with heavily pretreated multiple myeloma (MM), according to preliminary data from the phase Ib/II CARTITUDE-1 trial.
