Summary

This is a Phase 1 open label study designed to assess the safety and tolerability of the oncolytic herpes simplex virus 1 (oHSV1) study drug, MVR-C5252, administered intratumorally by convection-enhanced delivery (CED) in patients with recurrent high-grade glioma. Once the safety and maximum tolerated dose (MTD) is established in the dose escalation portion of the trial, a dose expansion cohort at the recommended phase 2 dose (RP2D) in patients with isocitrate dehydrogenase (IDH) wildtype recurrent glioblastoma (GBM) will evaluate preliminary efficacy of the study drug.

Conditions

  • Recurrent High Grade Glioma

Interventions

BIOLOGICAL

MVR-C5252

MVR-C5252 is a genetically modified next generation oncolytic herpes simplex virus 1 (oHSV1) with an active domain of human IL-12 and Fab fragment of anti-PD-1 antibody. This is a Phase 1 open label study designed to determine the safety and tolerability of MVR-C5252. The dose-escalation portion of the study will be conducted in 4 stages to evaluate the safety of infusion and determination of the MTD/RP2D followed by efficacy assessment.
