Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to see if the study drugs, lenvatinib and pembrolizumab, are effective in treating advanced Adenoid Cystic Carcinoma (ACC) or other salivary gland cancers that have come back and/or spread to other parts of the body. Researchers are also doing this study to test the safety of the study drugs in participants.

Cancers arising from non-salivary gland primary sites are allowed. Non-ACC Cohort (Cohort 2) only: Patients must have pathologically or cytologically confirmed salivary gland cancer of any histology (except for adenoid cystic carcinoma that is enrolled into cohort 1). Patients must have recurrent and/or metastatic disease not amenable to other curative intent therapy. At least 4 weeks must have elapsed since the end of prior systemic treatment and/or since completion of radiotherapy with resolution of all treatment related toxicity to NCI CTCAE Version 5.0 grade ≤1 (or tolerable grade 2) or back to baseline (except for alopecia, lymphopenia, or hypothyroidism) prior to starting study drug treatment. Patients must have RECIST V1.1 measurable disease defined as at least one non-nodal lesion measuring ≥ 20 mm with conventional techniques or as ≥10mm with CT scan, MRI, or calipers by clinical exam in the longest dimension AND/OR a nodal lesion measuring > 15 mm in the shortest dimension. Tumors in previously irradiated fields may be considered measurable if there is evidence of tumor progression after radiation treatment. Cohort 1 and acinic cell carcinoma patients in Cohort 2 only: Patients must have documentation of a new or progressive lesion on radiologic imaging study performed within 6 months prior to study enrollment (progression of disease over any interval is allowed) and/or new/worsening disease related symptoms within 6 months prior to study enrollment.
