Repurposing antiviral drugs to block mobile DNA in high‑risk neuroblastoma

Targeting retrotransposons for improved treatment of refractory childhood cancer

NIH-funded research Roswell Park Cancer Institute Corp · NIH-11106018

Researchers are looking at whether antiviral drugs called NRTIs can stop active mobile DNA elements in tumors to help children whose high‑risk neuroblastoma has come back or not responded to treatment.

What this research studies

Researchers will study tumor samples and laboratory models to see if active retrotransposons (mobile DNA elements) drive treatment resistance in pediatric neuroblastoma. They will test existing nucleoside reverse transcriptase inhibitors (NRTIs) in cell and animal models and analyze human tumor tissue to confirm the same mechanisms occur in children. The team will also explore combining NRTIs with immune‑based approaches to boost anti‑tumor effects. Because these antivirals are already used in patients for other reasons, promising results could speed the path toward clinical use for children with refractory disease.

Who could benefit from this research

Good fit: Children with relapsed or treatment‑refractory high‑risk neuroblastoma, especially those whose tumors have failed standard therapies and whose families can provide tumor samples or follow up with the research team.

Not a fit: Children with newly diagnosed low‑risk neuroblastoma, patients with other cancer types, or those unable or unwilling to provide tumor samples are unlikely to benefit directly from this program.

Why it matters

Potential benefit: Could provide a new, faster-to-deploy treatment option for children with relapsed or refractory high‑risk neuroblastoma by reversing a mechanism of drug resistance.

How similar studies have performed: Early lab studies and work in some adult cancers suggest retrotransposons can be targeted with NRTIs, but applying this approach to pediatric neuroblastoma is novel and not yet proven in children.
