Nivolumab and Radiation Therapy or Ipilimumab as Adjuvant Therapy in Treating Patients with Merkel Cell Cancer
This phase I trial studies the side effects and how well nivolumab works when given together with radiation therapy or ipilimumab as adjuvant therapy in treating patients with Merkel cell cancer. Immunotherapy with monoclonal antibodies, such as nivolumab and ipilimumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Radiation therapy uses high energy x-rays, gamma rays, neutrons, protons or other sources to kill tumor cells and shrink tumors. Giving nivolumab with radiation therapy or ipilimumab after surgery may kill any remaining tumor cells.

- Female subject of childbearing potential should have a negative urine or serum pregnancy at screening and within 24 hours prior to receiving the first dose of study medication and then every 4 weeks while on treatment. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
- Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 5 months after the last dose of study medication. Subjects should agree to ongoing pregnancy testing during the course of the study and after the end of study therapy. Female subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year
- Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 7 months after the last dose of study therapy. Males must refrain from donating sperm during study participation and for 7 months after the last dose of study medication. Female subject should agree to use an adequate method of contraception starting with the first dose of study therapy through 5 months after the last dose of study therapy
Exclusion Criteria
- Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment
- Has known central nervous system (CNS) metastases
- Has recurrent or metastatic MCC that is not completely resectable
- Has a known history of active TB (Bacillus tuberculosis)
- Hypersensitivity to any study agents
- Have received prior immunotherapy with any PD-1/PDL-1 inhibitors or CTLA-4 antibodies at any time in the past
- Has had prior chemotherapy or radiation therapy for treatment of MCC
- Has a clinically significant medical condition, which in the judgment of the attending physician would contraindicate immunotherapy or radiotherapy, such as serious autoimmune disease, hypersensitivity to investigational product or any component in its formulations, per Food and Drug Administration (FDA) prescription notice
- Subjects with prior history of non-Merkel cell carcinoma malignancies are excluded except * Adequately treated basal cell, squamous cell skin cancer, chronic lymphocytic leukemia (CLL) or other indolent malignancies not requiring therapy (ie. active surveillance) * Adequately treated malignancies and patient has been in complete remission for at least two years * Patients with history of breast cancer and no evidence of disease on hormonal therapy to prevent recurrence * Patients with prostate cancer on adjuvant hormonal therapy with undetectable PSA are eligible
- Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy (thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
- Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of randomization will be excluded. Inhaled or topical steroids are permitted in the absence of active autoimmune disease
- Has an active infection requiring intravenous systemic therapy
- Solid organ transplant recipients and patients with concurrent hematological malignancies including thymomas, leukemias (other than CLL) and lymphomas actively undergoing treatment or completed < 5 years prior

PRIMARY OBJECTIVE:
I. To assess the tolerability of two different experimental immunotherapy regimens in the adjuvant setting in patients with Merkel cell carcinoma (MCC).
SECONDARY OBJECTIVES:
I. To assess the safety and tolerability profile of each of the treatment using Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
II. To assess the efficacy of each of the treatment arms according to recurrence-free survival (RFS) at one and half years, defined as the time between the date of randomization and the date of first progression (local, regional or distant metastasis) or death (whatever the cause), whichever occurs first.
III. To assess the efficacy of each of the treatment arms according to overall survival (OS) at three years, defined from the time of randomization and the date of death, compared to historical registry control.
EXPLORATORY OBJECTIVE:
I. To explore potential biomarkers, next generation T cell receptor (TCR) sequencing will be performed to identify and longitudinally track individual T cell clones thus granting a comprehensive insight into immunological changes that occur in patients with MCC within the tumor and peripheral blood throughout the course of the disease.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients receive nivolumab intravenously (IV) over 30 minutes at week 0. Treatments repeat every 4 weeks for 1 year in the absence of disease progression or unacceptable toxicity. Beginning week 2, patients also undergo radiation therapy on Monday-Friday or 5 days per week for 6 weeks in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive nivolumab IV over 30 minutes and ipilimumab IV over 30 minutes at week 0. Treatments repeat every 2 weeks for nivolumab and 6 weeks for ipilimumab for up to 1 year in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days, every 3 months for up to 2 years, and then every 6 months for 1 year.
