Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults with histologically-confirmed grade 4 astrocytoma or glioblastoma who are hTERT positive and meet specific health criteria.

Probably not a fit

Patients with other malignant tumors, extracranial metastases, or a history of HIV may not benefit from this study.

What this trial studies

This Phase 1/2a study aims to assess the safety, tolerability, and preliminary efficacy of RZ-001 in combination with Valganciclovir (VGCV) for patients with hTERT-positive glioblastoma. The study is divided into two parts: the first part involves dose escalation to determine the maximum tolerated dose for intratumoral injection, while the second part focuses on expanding the dose to evaluate clinical activity based on findings from the first part. Participants will be closely monitored for safety and immune response.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with glioblastoma, potentially improving survival rates.

How similar studies have gone: While this approach is innovative, similar studies have shown promise in targeting glioblastoma, indicating potential for success.
