Targeted bone marrow radiation tested for myeloma relapse – trial halted early
NCT ID NCT01794572
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tested a combination of high-dose chemotherapy (melphalan) and escalating doses of total bone marrow irradiation, followed by a stem cell rescue, in 13 people with multiple myeloma that had returned after initial treatment. The goal was to find the highest safe radiation dose. The trial was terminated early, so results are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Total bone marrow irradiation and melphalan chemotherapy
- What this could lead to
- If successful, this approach could offer a more targeted way to deliver high-dose therapy before a stem cell transplant for relapsed multiple myeloma.
- What could go wrong
- This was a very early, small trial that was terminated before completion. The combination of high-dose radiation and chemotherapy carries significant risks, including severe side effects.
