Inclusion Criteria

• Male or female age = 18 years with histologically confirmed diagnosis of metastatic or recurrent SCCHN of the oral cavity, oropharynx, hypopharynx, or larynx. Disease must be unsuitable for curative surgical resection and must not be amenable to curative radiotherapy.

• Disease must have progressed after treatment with a platinum-containing regimen

• Subject must be candidate for intralesional therapy administration defined as one or more of the following:
- At least 1 injectable cutaneous, subcutaneous, or nodal SCCHN tumor = 10 mm in longest diameter
- Multiple injectable cutaneous, subcutaneous, or nodal SCCHN tumors that in aggregate have a longest diameter of = 10 mm

• Subject must have radiographically measurable disease

• ECOG performance status of 0 or 1

• Adequate organ function determined within 14 days prior to enrollment

• PTT or aPTT = 1.5 x ULN unless the subject is receiving anticoagulant therapy as long as PT and PTT/aPTT is within therapeutic range of intended use of anticoagulants. Female subject of childbearing potential must have a negative pregnancy test within 72 hours prior to enrollment. If urine pregnancy test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

• Phase 1b: Subject has a formalin fixed paraffin-embedded tumor sample (within 6 months prior to week 0, day 1 of the study, or newly obtained biopsy) from the primary or metastatic lesion that must be submitted within 4 weeks of enrollment for PD-L1, HPV-testing of oropharyngeal cancer (if not performed locally) and biomarker analyses.

Phase 3: Subject has a tumor sample and no systemic therapy given since the biopsy or newly obtained biopsy from the primary or metastatic lesion that is adequate for PD-L1 assessment prior to randomization

• Phase 3: Have results from local testing of HPV of tumor specimen for oropharyngeal cancer defined as p16 IHC testing using the CINtec® assay and a 70% cutoff point
