Clinical Trial Summary

This is an open-label study designed to evaluate safety and efficacy of enoblituzumab in combination with MGA012 or MGD013 in first-line treatment of patients with recurrent or metastatic squamous cell carcinoma of the head and neck (SCCHN).

Description:

The study will initially be conducted in 2 modules, Module X (enoblituzumab plus MGA012) and Module Y (enoblituzumab plus MGD013). Enrollment into Modules X and Y, with approximately 30 patients each, will occur independently in a non-randomized fashion. Data from these modules will determine if further evaluation will occur in randomized Module A (Phase 2) and randomized Module B (Phase 3).
