Inclusion criteria

* Histological or cytological confirmation of recurrent or metastatic HNSCC * Measurable disease as defined by RECIST v1.1 * PD-L1 positive

Exclusion criteria

* Diagnosis of recurrent or metastatic carcinoma of the nasopharynx, squamous cell carcinoma of unknown primary histology; or salivary gland or non-squamous histologies (e.g. mucosal melanoma) * Disease amenable to local therapy with curative intent (surgery or radiation therapy with or without chemotherapy) * Prior systemic anti-cancer therapy (use of chemotherapeutic agents, targeted small molecules, immunotherapy, or monoclonal antibodies) for the treatment of recurrent or metastatic HNSCC

MeasureTime frameDescription
Evaluation of Clinical Activity by the Objective Response Rate (ORR; Complete Response [CR] and Partial Response [PR]) Per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1Up to 25 monthsTo determine ORR of ADU-S100 in combination with pembrolizumab in subjects with recurrent or metastatic head and neck squamous cell cancer (HNSCC). ORR is defined as the percentage of subjects with evidence of a confirmed complete response (CR) or partial response (PR) as per Response Evaluation Criteria In Solid Tumors (RECIST) Version 1.1 and as assessed by the investigator.
