Summary:

      This is a study to determine the clinical benefit (how well the drug works), safety and
      tolerability of combining CDX-3379 and cetuximab. The study will enroll patients with
      advanced head and neck squamous cell carcinoma who have previously received cetuximab and
      progressed.

          3. Prior treatment with a check-point inhibitor targeting PD-1, unless not a candidate.

          8. Willingness to undergo a tumor biopsy prior to starting treatment (or if biopsy is not
             feasible, provide archival tissue).

        Exclusion Criteria:

          1. Previous treatment with CDX-3379 or other anti-ErbB3 targeted agents.

          3. Major surgery within 4 weeks prior to first dose of study treatment.

          4. Chemotherapy within 21 days or at least 5 half-lives (whichever is shorter) prior to
             first dose of study treatment.

          5. Monoclonal based therapies within 4 weeks (excluding cetuximab) and all other
             immunotherapy within 2 weeks prior to first dose of study treatment.

          6. Other prior malignancy, active within 3 years, except for localized prostate cancer,
             cervical carcinoma in situ, non-melanomatous carcinoma of the skin, stage 1
             differentiated thyroid cancer or ductal carcinoma in situ of the breast.

          7. Active, untreated central nervous system metastases.
