Patients receive nivolumab IV over 30 minutes on day 1 and cabozantinib PO QD of each cycle. Treatment repeats every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo ECHO during screening and as clinically indicated throughout the trial. Patients may undergo CT, MRI, or PET/CT at baseline, CT and MRI may be repeated every 6 months on study. Additionally, patients may undergo stool sample collection at baseline, and blood and tissue sample collection at baseline and on the trial.

This phase II trial tests whether nivolumab in combination with cabozantinib works in patients with mucosal melanoma. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It works by blocking the action of an abnormal protein that signals tumor cells to multiply. This helps stop the spread of tumor cells. Giving nivolumab in combination with cabozantinib could prevent cancer from returning.

PRIMARY OBJECTIVE:

I. To compare the efficacy of adjuvant nivolumab (480 mg every \[q\]4 weeks) versus nivolumab plus cabozantinib s-malate (cabozantinib) (40 mg daily) in patients with mucosal melanoma.

SECONDARY OBJECTIVES:

I. To compare overall survival between the two adjuvant therapies. II. To evaluate the adverse effects in each arm. III. To assess the correlation between PD-L1 expression in tumor cells with survival (recurrence free survival \[RFS\] and overall survival \[OS\]).

IV. To evaluate the overall response rate (ORR), duration of response (DOR), progression free survival (PFS), and OS of nivolumab plus cabozantinib in patients who cannot undergo gross total resection of disease or have metastatic disease at baseline.

V. Results of the primary analysis will be examined for consistency, while taking into account the stratification factors and/or covariates of baseline quality of life (QOL) and fatigue.

OUTLINE: Patients whose tumor has been fully removed by surgery are randomized to Arm 1 or Arm 2. Patients whose tumor has not been fully removed by surgery or has spread are assigned to Arm 3.

ARM 1: Patients receive nivolumab intravenously (IV) over 30 minutes on day 1 and cabozantinib orally (PO) once daily (QD) of each cycle. Treatment repeats every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity.

ARM 2: Patients receive nivolumab IV over 30 minutes on day 1 and placebo PO QD of each cycle. Treatment repeats every 28 days for up to 13 cycles in the absence of disease progression or unacceptable toxicity.

ARM 3: Patients receive nivolumab IV over 30 minutes and cabozantinib PO QD of each cycle. Treatment repeats every 28 days for up to 26 cycle in the absence of disease progression or unacceptable toxicity.

Patients undergo echocardiogram (ECHO) during screening and as clinically indicated throughout the trial. Patients may undergo computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET)/CT at baseline, CT and MRI may be repeated every 6 months on study. Additionally, patients may undergo stool sample collection at baseline, and blood and tissue sample collection at baseline and on the trial.

After completion of study treatment, patients are followed up every 3 months until disease progression, and then every 6 months for up to 5 years from registration or until death.

Using Nivolumab Alone or With Cabozantinib to Prevent Mucosal Melanoma Return After Surgery

A Randomized Phase II Trial of Adjuvant Nivolumab With or Without Cabozantinib in Patients With Resected Mucosal Melanoma

NCI is committed to sharing data in accordance with NIH policy. For more details on how clinical trial data is shared, access the link to the NIH data sharing policy page

Will evaluate RFS of single agent adjuvant nivolumab plus placebo compared to the combination treatment of adjuvant nivolumab plus cabozantinib in patients with resected mucosal melanoma.

Will be evaluated utilizing the Kaplan-Meier (KM) method and, when appropriate, cox proportional hazards models. Median OS is calculated (along with 95% Confidence intervals) using the KM method. A Cox proportional hazards model is built to compare arms 1 and 2 with respect to OS.

Median RFS will be calculated (along with 95% Confidence intervals) using the KM method. A Cox proportional hazards model will also be built to compare arms 1 and 2 with respect to RFS, with and without stratifying for PD-L1 categorization. For non-resected cohort, If a patient in this group has surgery, their PFS data will be censored at the time of surgery.

Will be evaluated in multiple settings utilizing the KM method and, when appropriate, cox proportional hazards models.

A KM analysis is performed to calculate the median duration of response and 95% confidence intervals are constructed.

The maximum grade for each type of adverse event will be summarized using Common Terminology Criteria for Adverse Events version 5.0. The frequency and percentage of grade 3+ adverse events will be summarized.
