Brief Summary:
This phase II trial studies the effect of pemetrexed and pembrolizumab in treating patients with salivary gland cancer that has come back (recurrent) and/or has spread to other places in the body (metastatic). Chemotherapy drugs, such as pemetrexed, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The purpose of this study is to evaluate whether pembrolizumab, an immunotherapy drug, in combination with the chemotherapy drug, pemetrexed, has an effect on advanced salivary gland cancer.

Detailed Description:

PRIMARY OBJECTIVE:

I. To determine the response rate of the combination of pembrolizumab and pemetrexed in patients with recurrent or metastatic salivary gland cancer (R/M SGC).

SECONDARY OBJECTIVES:

I. To determine the progression-free survival (PFS), overall survival (OS), and adverse events of the combination of pembrolizumab and pemetrexed in patients with recurrent or metastatic salivary gland cancer (R/M SGC).

II. To assess safety and tolerability of the combination of pembrolizumab and pemetrexed in patients with recurrent or metastatic salivary gland cancer (R/M SGC).

CORRELATIVE RESEARCH OBJECTIVES:

I. To investigate the frequency of MTAP loss by immunohistochemistry in R/M SGC and whether it correlates with enhanced response to pemetrexed.

II. To measure the degree of PDL1 expression using formalin-fixed tumor samples, and determine the extent of PDL1 expression correlates with response to study treatment.

III. To investigate expression of thymidylate synthase by immunohistochemistry in R/M SGC and whether it correlates with enhanced response to pemetrexed.

IV. To investigate circulating tumor deoxyribonucleic acid (DNA) (ctDNA) and correlation with response to study treatment.

OUTLINE:

Patients receive pembrolizumab intravenously (IV) over 30 minutes and pemetrexed disodium IV over 10 minutes on day 1. Treatment with pembrolizumab repeats every 21 days for up to 35 cycles (2 years) in the absence of disease progression or unacceptable toxicity. Cycles of pemetrexed disodium repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients who had stable disease, partial response, or complete response after completion of 35 cycles of pembrolizumab, may continue pembrolizumab for an additional 17 cycles (1 year) in the absence of disease progression or unacceptable toxicity.

After completion of study intervention, patients are followed up at 30 days, and then every 3 months for up to 3 years.
