rHSC-DIPGVax Plus Checkpoint Blockade for the Treatment of Newly Diagnosed DIPG and DMG
Trial Parameters
Brief Summary
This is a phase I, open label, plus expansion clinical trial evaluating the safety and tolerability of rHSC-DIPGVax in combination with BALSTILIMAB and ZALIFRELIMAB. rHSC-DIPGVax is an off-the-shelf neo-antigen heat shock protein containing 16 peptides reflecting neo-epitopes found in the majority of DIPG and DMG tumors. Newly diagnosed patients with DIPG and DMG who have completed radiation six to ten weeks prior to enrollment are eligible.
Eligibility Criteria
Inclusion Criteria: * Subjects with newly diagnosed typical or non-typical, biopsy-proven DIPG or DMG are eligible for study enrollment. Biopsy is not required for subjects with radiographically typical DIPG meeting imaging criteria. Biopsy is required for DMG's and non-radiographically typical DIPG. Histone mutation must be confirmed by pathology report. Radiographically typical DIPG defined as a tumor with a pontine epicenter and diffuse involvement of more than 2/3 of the pons. = Subjects ages \> or = to 12 months and \< or = 18 years ("Lead In", Part A, and Part B require first three patients be \> or = to 12 years of age) * BSA \> or = 0.35m2 at the time of study enrollment * Performance score: Karnofsky \>50% of subjects \>16 years of age and Lansky \> or = 50 for subjects \< or = 16 years of age.
