GR-MD-02 Plus Pembrolizumab in Melanoma, Non-small Cell Lung Cancer, and Squamous Cell Head and Neck Cancer Patients

This study will employ a 3+3 phase I design with dose escalation of GR-MD-02 in conjunction with the standard therapeutic dose of pembrolizumab in patients with advanced melanoma who have had progression after ipilimumab and/or BRAF targeted therapy when a BRAF mutation is present, non-small cell lung cancer patients with disease progression after targeted therapy, or head and neck squamous cell carcinoma patients with disease progression after at least one platinum-containing regimen. In addition to monitoring for toxicity and clinical response, blood and tumor samples will be obtained to assess immunologic measures relevant to galectin biology and pembrolizumab T-cell checkpoint inhibition.
