• Female patients of reproductive potential and their male partners must agree to practice total abstinence or use a highly effective method of contraception (failure rate < 1% per year) prior to study entry, during treatment and for 90 days following the last dose of study treatment.
• Male patient agrees to use an adequate method of contraception

You may not qualify if…

• Histologically confirmed other types (Non-SCC) of salivary gland cancer
• History of another primary malignancy EXCEPT For:
• malignancy treated with curative intent and with no known active disease ≥5 years before the first dose of study drug and of low potential risk for recurrence;
• adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease; adequately treated carcinoma in situ without evidence of disease (eg, carcinoma in situ of the breast, oral cavity and cervix are all permissible);
• low to favorable intermediate risk prostate cancer based on NCCN criteria on active surveillance, .
• Prior radiotherapy to the region of the study cancer within less than 6 months
• Patients who have received prior radiation therapy and who, in the opinion of the treating radiation oncologist, cannot be reirradiated safely without excess risk of severe toxicity given prior radiation dose to critical structures.
• Patients with known contraindications to radiotherapy, including inherited syndromes associated with hypersensitivity to ionizing radiation (e.g., Ataxia-Telangiectasia, Nijmegen Breakage Syndrome)
• Patients with inadequate renal function or other contraindications to IV contrast
• Any previous treatment with PD-1 or PD-L1 inhibitors, including pembrolizumab
