About

This is a single-arm, non-randomized, open-label Phase 2 therapeutic study that will assess the effects of adding BPM31510 onto a conventional treatment framework of RT and concurrent TMZ chemotherapy for subjects with newly diagnosed glioblastoma.

Full description

The study will start with a dose-confirmation phase to establish safety of BPM31510 in combination with RT and TMZ. This phase will follow a standard 3+3 dose design with the starting dose of BPM31510 at 110 mg/kg/week (wk), with 1 potential dose de-escalation to 66 mg/kg/wk in the event a DLT is experienced at the 110 mg/kg dose. Toxicity at this dose level will be graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 5 (CTCAE v5). Subjects will be monitored for DLTs associated with combination therapy for 30 days (d) (± 5 d) after the end of RT (DLT assessment period). Subjects will continue to be monitored for late radiation-related DLTs during follow up, every 8 wk (± 2 wk) during the first 12 months (mo), and then every 12 wk (± 2 wk) for a total of 5 years (y). Safety oversight will be provided by the independent Data and Safety Monitoring Committee (DSMC). The DSMC will review and confirm all DLT data, make recommendations for dose modifications, if necessary, and continue to monitor safety throughout the study. The efficacy phase of the study will begin after the recommended Phase 2 dose (RP2D) has been confirmed.

BPM31510, Vitamin K1, RT and TMZ

Experimental group

Description:

Subjects will receive a BPM31510 96hr infusion once weekly for 8 wk. Prophylactic Vitamin K1 at a recommended dose of 10 mg will be given intramuscular (IM) to all subjects prior to the beginning of each week of therapy. After 2 wk of treatment with BPM31510, subjects will start concurrent standard RT and TMZ 75 mg/m2 once daily (qd) × 42 days. Subjects will receive the standard TMZ treatment for additional 6 cycles post BPM31510 treatment.

Radiation: Radiation

Drug: Temozolomide (TMZ)

Drug: BPM31510

Other: Vitamin K1
