Can a vaccine and immune drug keep myeloma away after transplant?
NCT ID NCT01067287
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested a drug called CT-011 (a PD-1 blocker) and a dendritic cell vaccine given after a stem cell transplant in 35 people with multiple myeloma. The goal was to see if this combination is safe and can boost the immune system to fight remaining cancer cells. Researchers measured immune response by looking at T cell activity, hoping to delay or prevent the disease from coming back.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Pidilizumab (CT-011) and dendritic cell fusion vaccine
- What this could lead to
- If successful, this combination could help prevent or delay multiple myeloma from coming back after a stem cell transplant.
- What could go wrong
- This is a small, early-phase trial with only 35 participants. The treatment may not work for everyone and could cause side effects like immune reactions.
