15-Year Follow-Up begins for myeloma cell therapy patients
NCT ID NCT03741127
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows about 100 people with multiple myeloma who previously received an experimental cell therapy called P-BCMA-101. Researchers will monitor them for up to 15 years to see how safe and effective the treatment remains over time. A safety switch drug called rimiducid may also be given if needed.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- P-BCMA-101 (a type of cell therapy) and rimiducid (a safety switch activator)
- What this could lead to
- If successful, this could show that P-BCMA-101 provides lasting control of multiple myeloma with manageable long-term side effects.
- What could go wrong
- This is an early-phase follow-up study, not a large trial. It may not prove long-term benefit, and risks like delayed side effects or loss of effectiveness remain possible.
