A Phase 1/2 Immunotherapy Study of Evofosfamide in Combination with Zalifrelimab and Balstilimab in Patients with Advanced Solid Malignancies
ImmunoGenesis
Summary
The purpose of this Phase 1/2 study is to test the overall safety, tolerability, and effectiveness of the combination investigational drugs evofosfamide, zalifrelimab, and balstilimab in treating advanced or metastatic castration-resistant prostate cancer, pancreatic cancer, and human papilloma virus (HPV)-negative squamous cell carcinoma of the head and neck (SCCHN).
Description
Tumor hypoxia can lead to poor effector T-cell penetration and immunosuppressive signaling via myeloid-derived suppressor cells, myofibroblasts, and regulatory T-cells. Disruption of these hypoxic regions within the tumor microenvironment by the hypoxia-directed cytotoxic agent evofosfamide may enhance the ability of immune checkpoint inhibitors to reject otherwise resistant solid tumors. The hypothesis tested in this study is that evofosfamide, by specifically targeting the hypoxic tumor microenvironment, may enhance the anti-tumor effects of the immune checkpoint inhibitors zalifrelimab (ant…
