Can a new chemo combo help kids whose solid tumors came back?
NCT ID NCT02013336
First seen Oct 08, 2026 · Last updated Oct 09, 2026 · Updated 1 time
Summary
Researchers are testing a combination of two chemotherapy drugs, MM-398 and cyclophosphamide, in children and young adults with solid tumors that have returned or stopped responding to treatment. The trial includes patients with Ewing sarcoma, rhabdomyosarcoma, neuroblastoma, or osteosarcoma. The main goal is to find the highest dose of MM-398 that can be given safely alongside cyclophosphamide.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MM-398 (irinotecan sucrosofate liposome injection) plus cyclophosphamide
- What this could lead to
- If the combination proves safe, it could offer a new treatment option for children with solid tumors that have come back or stopped responding to other therapies.
- What could go wrong
- This is an early-stage trial with a small number of participants, so it may not find a safe dose or show benefit. Combining two chemotherapy drugs can cause serious side effects.
