Crizanlizumab Alone or in Combination With Nivolumab for Glioblastoma and Melanoma With Brain Metastases

A single-center, open-label, non-randomized phase I/II study to evaluate the efficacy, safety and tolerance of crizanlizumab monotherapy and in combination with nivolumab in patients with advanced glioblastoma (GB) who exhausted standard of care (SOC) therapy, patients with metastatic brain melanoma (MBM) and patients with newly diagnosed unmethylated GB. Subjects will be screened for up to 28 days prior to treatment initiation. Eligible subjects will be allocated to one of 3 cohorts: Cohort 1: Patients with metastatic melanoma with primarily diagnosed or newly progressing brain metastases who failed immunotherapy. Cohort 2: Patients with recurrent or progressing GB following primary radiation therapy and temozolomide. Patients may have failed up to 2 prior systemic treatment lines (including temozolomide as adjuvant therapy) and are candidates for further treatment. Cohort 3: Patients with newly diagnosed GB who were evaluated for methylguanine-DNA methyltransferase(MGMT) methylation status and have un-methylated MGMT promotor-therefore, they are not candidates for maintenance temozolomide therapy.
