What this trial studies

This study aims to gather long-term follow-up data on delayed adverse events in patients who have previously received ciltacabtagene autoleucel (cilta-cel) for multiple myeloma. It focuses on characterizing the long-term safety profile of this CAR-T therapy, which targets B-cell maturation antigen (BCMA). Participants will not receive any new treatment during the study; instead, they will be monitored for adverse events, laboratory results, and physical examinations over a period of up to 15 years. The study is divided into two phases: the first five years after the last dose and then from year six to fifteen.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term safety and potential toxicities associated with cilta-cel treatment.

How similar studies have gone: Other studies on CAR-T therapies have shown success in understanding long-term effects, making this approach both relevant and necessary.
