Can a Two-Drug combo outsmart childhood cancers that resist treatment?
NCT ID NCT00412503
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This early-stage trial is testing whether combining two chemotherapy drugs, temozolomide and topotecan, is safe and tolerable for children and adolescents with malignant tumors that have returned or not responded to standard treatments. The study aims to find the highest safe dose of each drug when used together, while also checking how the body processes them and whether the combination shows any signs of shrinking tumors. Participants must have a confirmed cancer with no curative options available and be healthy enough to undergo treatment.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A combination of two chemotherapy drugs: temozolomide and topotecan
- What this could lead to
- If the combination proves safe and effective, it could offer a new treatment option for children with hard-to-treat cancers that have not responded to standard therapies.
- What could go wrong
- This is an early-phase trial focused on safety and dosing, so the combination may not work as hoped. There are also risks of side effects from the chemotherapy drugs.
