Open-Label Study to Evaluate the Safety, Tolerability and Efficacy of the Oncolytic HSV1 MVR-C5252 (NCT06126744)

The PuMP Trial: "A Multistage Phase 1 Open-Label Study to Evaluate the Safety, Tolerability and Efficacy of the Oncolytic HSV1 MVR-C5252 in Patients With Recurrent High-Grade Glioma"

🟢 Recruiting Phase1 💊 Investigational Drug / Biologic Sponsor: Duke University

🩺 Plain-English Summary (8th-Grade Level)

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.
