About this trial

This phase II trial studies the effect of pembrolizumab alone compared to the usual approach (chemotherapy \[cisplatin and carboplatin\] plus radiation therapy) after surgery in treating patients with head and neck squamous cell carcinoma that has come back (recurrent) or patients with a second head and neck cancer that is not from metastasis (primary). Radiation therapy uses high energy radiation or protons to kill tumor cells and shrink tumors. Cisplatin is in a class of medications known as platinum-containing compounds. It works by killing, stopping or slowing the growth of cancer cells. Carboplatin is also in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping or slowing the growth of cancer cells. 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. Giving pembrolizumab alone after surgery may work better than the usual approach in shrinking recurrent or primary head and neck squamous cell carcinoma.

Trial outcomes

Primary outcomes

1

Overall survival (OS)

Kaplan-Meier estimates will be used to estimate the OS distributions. A log-rank test with one-sided 10% type I error will be used for the comparison.

Time frame
From randomization to date of death from any cause, measured at 2 years
2

Incidence of adverse events

Assessed using Common Terminology Criteria for Adverse Events. An 80% confidence interval around the hazard ratio of the two experimental arms will be calculated. Toxicity will be compared between the two treatment arms. Toxicity will be examined by arm and compared using the Fisher's exact test.

Time frame
Up to 5 years from date of registration

Secondary outcomes

1

Disease free survival

Time frame
From the date of randomization to the date of recurrence, second primary tumor from the head and neck region, or death, assessed up to 5 years from date of registration
2

PD-L1 expression

Defined as Combined Positive Score \>= 20 as a predictive marker of efficacy.

Time frame
Up to 5 years from date of registration
