Official title
A Multi-Center Phase 0/I Trial of Anti-TIGIT Antibody AB154 in Combination With Anti-PD-1 Antibody AB122 for Recurrent Glioblastoma.
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a phase 0/I exploratory study. Patients at first or second recurrence of glioblastoma will be enrolled. The study will be divided into two cohorts: Cohort A (safety cohort) and Cohort B (surgical patient cohort). Cohort A: Eligible patients will be sequentially enrolled to receive intravenous domvanalimab combined with zimberelimab (N=6). Domvanalimab will be given at a dose of 10 mg/kg and zimberelimab will be given at a dose of 240 mg (flat). The dosing was determined in a separate study in solid tumors; this cohort will confirm the safety of the dosing schedule in patients with brain tumors. Cohort B: Expansion surgical cohort. The purpose of cohort B is to provide an additional safety evaluation of domvanalimab + zimberelimab as well as tissue and blood for exploratory ancillary studies investigating the effects of domvanalimab + zimberelimab in the tumor and tumor microenvironment. A total of 46 patients will be enrolled in this cohort.
