A new telomerase-targeting drug (6-thio-dG) for adult glioblastoma

6-thio-2'-deoxyguanosine: A Novel Immunogenic Telomerase-Mediated Therapy in Glioblastoma - A Duke and UTSW Collaboration

NIH-funded research Duke University · NIH-11164683

This project sees if the drug 6‑thio‑dG, which targets telomerase, can trigger immune responses and help shrink tumors in adults with glioblastoma.

What this research studies

If you have glioblastoma, this project is studying a drug called 6‑thio‑dG that targets an enzyme (telomerase) common in these tumors. Researchers will use lab-grown tumor models and animal experiments to examine how the drug causes DNA damage and activates both innate and adaptive immune responses. Those lab findings will be used to design an early clinical trial that could open to adults with GBM at Duke, UTSW, or partner sites. The team combines tumor biology, immune studies, and trial planning to move promising lab results toward patient testing.

Who could benefit from this research

Good fit: Adults (21+) diagnosed with glioblastoma who meet clinical eligibility and can travel to participating centers would be the primary candidates.

Not a fit: People whose tumors lack telomerase activity, those in poor overall health, or those unable to attend trial centers may not receive benefit from this effort.

Why it matters

Potential benefit: If successful, this approach could become a new targeted treatment that shrinks tumors and boosts the immune system against glioblastoma, potentially improving outcomes with fewer off-target effects.

How similar studies have performed: Preclinical animal studies of 6‑thio‑dG and related telomere-targeting approaches have shown tumor regression and immune activation, but human effectiveness is not yet proven and clinical testing is still needed.
