Spots Global Cancer Trial Database for Phase 2 Study of Durvalumab (MEDI4736) in Patients With Glioblastoma

Study Description

Brief Summary: This is an ongoing Phase 2, open-label, multicenter, non-randomized study of MEDI4736 (durvalumab) in subjects with glioblastoma (GBM) enrolled into 5 non-comparative cohorts. Primary study objectives, which vary by cohort due to differences in subject populations, include evaluation of the clinical efficacy as measured by the overall survival (OS) rate at 12 months (Cohort A), progression-free survival (PFS) at 6 months (Cohorts B, B2, and B3), and OS at 6 months (Cohort C). For all cohorts, secondary objectives include evaluation of the safety/tolerability and clinical efficacy of study treatment, and exploratory objectives include evaluation of the neurologic function and correlative biomarkers.

Detailed Description: Eligible subjects are enrolled in parallel into one of the following 5 cohorts as described below. In each cohort, the first study drug administration for the first subject and the second subject are separated by at least 1 week. * Cohort A: Subjects with newly diagnosed unmethylated O\^6-methylguanine-deoxyribonucleic acid methyltransferase (MGMT) GBM receive durvalumab (10 mg/kg every 2 weeks \[Q2W\]) + standard radiotherapy. The first 6 subjects are evaluated for dose-limiting toxicity (DLT) for 10 weeks to determine whether the durvalumab dose should be lowered to 3 or 1 mg/kg. * Cohort B: Bevacizumab-naïve subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) as monotherapy. * Cohort B2: Bevacizumab-naïve subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) + bevacizumab (10 mg/kg Q2W). * Cohort B3: Bevacizumab-naïve subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) + bevacizumab (3 mg/kg Q2W). * Cohort C: Bevacizumab-refractory subjects with recurrent GBM receive durvalumab (10 mg/kg Q2W) + continued bevacizumab (10 mg/kg Q2W). The first 6 subjects are evaluated for DLTs for 6 weeks to determine whether the durvalumab dose should be lowered to 3 or 1 mg/kg. The Core Study lasts for up to 12 months; optional extension treatment may be offered to subjects who complete 51 weeks of treatment on the Core Study with stable disease or better and upon agreement between the subject, Investigator, and Sponsor. Subjects are followed on study for 90 days after the last drug administration and off study every 6 months for 3 years from the date of the first dose of study treatment. The primary study endpoints have been met, although some subjects remain in treatment and/or follow-up and data collection is ongoing.
