Summary

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.

Description

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.

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.

requirements
Head/neck - any primary lesion if sinonasal; pT4a or above for nasal or oral cavity, given slightly improved OS

Urinary tract - any primary urethral or bladder tumor
Penile
Vulvar- AJCC cutaneous stage IIB or higher
Esophageal/gallbladder - any primary
Locoregionally recurrent following prior resection, meeting at least one of the
above criteria
In addition, patients must have undergone cross-sectional imaging of the brain, chest, abdomen and pelvis with no evidence of distant metastatic disease
Disease status-Non-resected R2 or metastatic disease patients
Non-resected R2 or metastatic disease that is assessable and measurable radiographically or by physical examination
Prior Treatment
No prior systemic checkpoint inhibitor therapy of mucosal melanoma, including in the adjuvant setting, is allowed. Prior adjuvant chemotherapy or interferon is allowed
No other active, concurrent malignancy that requires ongoing systemic treatment or interferes with radiographic assessment of melanoma response as determined by the investigator
Any radiation must have completed 28 days prior to randomization and the patient must have adequately recovered from its effects
Surgery must have completed 28 days prior to randomization
Surgery must have completed no more than 84 days prior to randomization
Not pregnant and not nursing, because this study has an agent that has known
genotoxic, mutagenic and teratogenic effects. Therefore, for women of
childbearing potential only, a negative pregnancy test done =< 7 days prior to
registration is required
