New drug cocktail aims to keep childhood cancers at bay
NCT ID NCT04469530
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 2 trial tests whether a year-long maintenance regimen of sirolimus (rapamycin) plus low-dose oral chemotherapy and celecoxib can improve 2-year survival without cancer progression in children with high-risk solid tumors. About 55 children and young adults (ages 1–30) who have completed standard therapy will receive the drug combination. The results will be compared to historical data from similar patients who only had observation after standard treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- sirolimus (rapamycin) and low-dose chemotherapy (metronomic chemotherapy) with celecoxib
- What this could lead to
- If successful, this maintenance regimen could help keep high-risk solid tumors from returning in children, improving long-term survival rates.
- What could go wrong
- This is a phase 2 trial with only 55 participants, comparing results to past patients rather than a control group. The combination may cause side effects and might not improve survival.
