A Study to Evaluate Pemetrexed and Pembrolizumab to Treat Recurrent and/or Metastatic Salivary Gland Malignancies

Overview

About this study

The purpose of this study is to determine the response rate of the combination of Pemetrexed and Pembrolizumab in patients with recurrent or metastatic salivary gland cancer (R/M SGC).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:
