Secondary Objective:

To further compare the efficacy of INBRX-106 + pembrolizumab vs pembrolizumab
To evaluate the safety and tolerability of INBRX-106 + pembrolizumab vs pembrolizumab
To compare the impact of INBRX-106 + pembrolizumab vs pembrolizumab on pain, function, and HRQoL

Eligibility

Inclusion Criteria:

Has histologically or cytologically confirmed diagnosis of metastatic, recurrent head and neck squamous cell carcinoma (HNSCC) that is considered incurable by local therapies.
Has tumor PD-L1 expression of CPS ≥20. Tumor tissue must be provided for PD-L1 biomarker analysis.
Has human papilloma virus (HPV) testing results for oropharyngeal cancer by p16 immunohistochemistry (IHC) testing.
Has measurable disease per RECIST 1.1 guidelines.
Has the primary tumor location of the oral cavity, oropharynx, hypopharynx, or larynx.
Has an Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1.
Female patients of childbearing potential must have a negative highly sensitive pregnancy test within 72 hours prior to randomization and must not be breastfeeding.
Male and female patients of childbearing potential must be willing to completely abstain from heterosexual sex or agree to use a highly effective method of contraception.

Exclusion Criteria:

Has primary tumor site (any histology) of nasopharynx or salivary glands or occult primary site.
Has received prior systemic therapy (eg, prior chemo-, immune-, or biologic therapy) for locally advanced unresectable or metastatic HNSCC.

Prior systemic therapy completed >6 months prior to signing informed consent is allowed if given as part of multimodal treatment for locoregionally advanced disease with curative intent, and no PD/recurrence occurred within 6 months of its completion. Prior systemic immunotherapy in the locoregionally advanced disease with curative intent, including but not limited to anti-PD-(L)1 agents, is allowed if PD/recurrence occurred ≥12 months after its completion.

Has clinically active central nervous system metastases and/or carcinomatous meningitis.
Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of study treatment.
Rapidly progressing disease or with features that may confer a high risk of tumor-associated hemorrhage or uncontrolled tumor pain.
