Brief 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).
Detailed 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).
Interventions
anti-B7-H3 antibody
anti-PD-1 antibody
PD-1 X LAG-3 bispecific DART protein

Intervention model description
Parallel study model refers to concurrent enrollment of non-randomized Modules X and Y.
Eligibility
Inclusion criteria
* Histologically proven, recurrent or metastatic SCCHN not curable by local therapy * No prior systemic therapy for SCCHN in the recurrent or metastatic setting (with the exception of systemic therapy completed \> 6 months prior of given as part of multimodal treatment for locally advanced disease) * Primary tumor locations of oropharynx, oral cavity, hypopharynx, or larynx * At least one radiographically measurable lesion * HPV test results available (positive and negative eligible) * ECOG Performance status of 0 or 1 * Adequate end organ function * Positive PD-L1 expression level (CPS ≥ 1%)
Exclusion criteria
* Disease suitable for local therapy administered with curative intent * Progressive disease within 6 months of completion of curatively intended systemic treatment for locoregionally advanced SCCHN * Radiation or other non-systemic therapy within 2 weeks of first dose of study drug * Diagnosis of immunodeficiency, or use of immunosuppresive therapy within 14 days of first dose of study drug
