A Study to Evaluate the Safety, Tolerability and Efficacy of RZ-001 with Valganciclovir (VGCV) in Subjects with Glioblastoma

Phase 1
Recruiting
Conditions
Glioblastoma
Interventions
Combination Product: VGCV
Registration Number
NCT06102525
Lead Sponsor
Rznomics, Inc.
Brief Summary

This is a Phase 1/2a, open-label study to evaluate the safety, tolerability, immunogenicity, and preliminary clinical activity of RZ-001 administered in combination with VGCV in subjects with hTERT-positive GBM.

Detailed Description

The study consists of 2 parts: a dose-escalation part (Part 1) and a dose-expansion part (Part 2).

Part 1 consists of dose escalation exploring MTD/RP2D for intratumoral (IT) injection.

Part 2 will consist of dose expansion exploring clinical activity for the optimal fixed dose based on the results of Part 1.
