Descriptive Information

• Brief Title: Pembrolizumab in Treating Patients With High Risk Oral Intraepithelial Neoplasia
• Official Title: Personalized, Randomized, Phase 2 Study of Pembrolizumab (MK-3475) for High Risk Oral Intra-Epithelial Neoplasias
• Brief Summary: This randomized phase II trial studies how well pembrolizumab works in treating patients with high risk oral intraepithelial neoplasia. 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.

Detailed Description

PRIMARY OBJECTIVE:

I. To determine oral cancer-free survival of patients with high risk oral intra-epithelial neoplasias (IEN) treated with pembrolizumab versus observation.

SECONDARY OBJECTIVES:

I. To determine the safety and tolerability of pembrolizumab for patients with oral IEN.

II. To determine the histologic and clinical response rates (in the subgroup of patients with clinically evident measurable oral IEN lesions) to pembrolizumab.

III. To characterize the immune infiltrate in oral IEN lesions before and after treatment with pembrolizumab.

EXPLORATORY OBJECTIVES:

I. To assess predictive, tissue-and blood-based, biomarkers of benefit from pembrolizumab in oral IEN.

II. To determine the presence of neo-antigens in IEN lesions before and after treatment, and their correlation with oral cancer-free survival and immune infiltrate characteristics.

III. To evaluate the oral micro-biome before and after treatment with pembrolizumab and its association with neo-antigens and benefit from treatment.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients undergo observation.

ARM B: Patients receive pembrolizumab intravenously (IV) over 30 minutes on day 1. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 6, 9, 12, 18, 24, 30, and 36 months and then periodically thereafter.

Eligibility Criteria

Inclusion Criteria:

• Histological evidence of oral intra-epithelial neoplasia within 12 months prior to enrollment; subjects with a history or clinical diagnosis suggestive of oral intra-epithelial neoplasia, or patients with a history of invasive oral cancer are eligible, but must have a confirmed histological diagnosis of oral intra-epithelial neoplasia before randomization; histological evidence of oral intraepithelial neoplasia on an invasive oral cancer resection specimen is acceptable; a visible, measurable, clinical lesion (such as leukoplakia and/or erythroplakia) is not required; only individuals with high risk profiles will be considered eligible for randomization; high risk profiles are defined as patients without a prior oral cancer and have loss of heterozygosity (LOH) at 3p14 and/or 9p21 plus at least at one additional chromosomal site (4q,8p,11p,13q, or 17p) or patients with a prior oral cancer history and have LOH at 3p14 and/or 9p21; all high risk patients must also meet the additional eligibility criteria
• Be willing and able to provide written informed consent
• Be greater than or equal to 18 years of age on day of signing informed consent for the trial

• Absolute neutrophil count >= 1,500/mcL
