Brief Summary

This phase II trial studies how well nivolumab with or without ipilimumab works in treating patients with anal canal cancer that has not responded to previous treatment (refractory) and that has spread from where it first started (primary site) to other places in the body (metastatic). 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.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate overall response rate (ORR) with nivolumab in patients with previously treated metastatic squamous cell carcinoma (SCCA) of the anal canal. (Part A) II. To determine an improvement in progression-free survival (PFS) when nivolumab is combined with ipilimumab versus (vs.) nivolumab alone in patients with previously treated metastatic SCCA (Part B).

SECONDARY OBJECTIVES:

I. To evaluate progression-free survival (PFS) of nivolumab in patients with previously treated metastatic SCCA of the anal canal. (Part A) II. To evaluate overall survival (OS) in patients with previously treated metastatic SCCA of the anal canal treated with nivolumab. (Part A) III. To evaluate the grade 3 and 4 toxicity rate in patients with previously treated metastatic SCCA of the anal canal when treated with nivolumab. (Part A) IV. To evaluate the overall response rate (ORR) of nivolumab plus or minus ipilimumab in patients with previously treated metastatic SCCA of the anal canal. (Part B) V. To evaluate overall survival (OS) in patients with previously treated metastatic SCCA of the anal canal treated with nivolumab plus or minus ipilimumab. (Part B) VI. To evaluate the grade 3 and 4 toxicity rate in patients with previously treated metastatic SCCA of the anal canal when treated with nivolumab plus or minus ipilimumab. (Part B)

EXPLORATORY OBJECTIVES:

I. To evaluate ORR, PFS, and OS based on expression of programmed cell death 1 ligand 1 (PD-L1), programmed cell death 1 (PD-1), peritumoral cluster of differentiation (CD)8+ tumor infiltrating lymphocytes (TILs), peritumoral CD4+ TILs, and regulatory T cells as analyzed from tumor biopsies in previously treated patients with metastatic SCCA of the anal canal when treated with nivolumab. (Part A) II. To evaluate radiographic responses according to relative changes in proportions of anti-human papillomavirus (HPV) specific CD8+ and CD4+ TILs and regulatory T cells in patients with previously treated metastatic SCCA of the anal canal following treatment with nivolumab, analyzed from serial peripheral blood samples. (Part A) III. To evaluate ORR, PFS, and OS based on expression of PD-L1, PD-1, peritumoral CD8+ tumor infiltrating lymphocytes (TILs), peritumoral CD4+ TILs, and regulatory T cells as analyzed from tumor biopsies in previously treated patients with metastatic SCCA of the anal canal when treated with nivolumab plus or minus ipilimumab. (Part B) IV. To evaluate radiographic responses according to relative changes in proportions of anti-HPV specific CD8+ and CD4+ TILs and regulatory T cells in patients with previously treated metastatic SCCA of the anal canal following treatment with nivolumab plus or minus ipilimumab. (Part B)

OUTLINE:

PART A: Patients receive nivolumab intravenously (IV) over 60 minutes once every two weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scan, magnetic resonance imaging (MRI) and blood sample collection throughout the study.

PART B: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive nivolumab IV over 30 minutes once every 4 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan, MRI and blood sample collection throughout the study.

ARM II: Patients receive nivolumab as in Arm I. Patients also receive ipilimumab IV over 30 minutes once every 8 weeks. Treatment continues in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan, MRI and blood sample collection throughout the study.

After completion of study treatment, patients are followed up for 100 days and then every 3 months for 2 years.

• Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she (or the participating partner) should inform the treating physician immediately; if, following initiation of the investigational product, it is subsequently discovered that a study subject is pregnant or may have been pregnant at the time of investigational product exposure, including during at least 6 half-lives after product administration, the investigational product will be permanently discontinued in an appropriate manner (e.g., dose tapering if necessary for subject safety); the investigator must immediately notify BMS of this event and record the pregnancy on the Pregnancy Surveillance Form (not an severe adverse event [SAE] form); initial information on a pregnancy must be reported immediately to BMS, and the outcome information provided once the outcome is known; completed Pregnancy Surveillance Forms must be forwarded to BMS according to SAE reporting procedures; any pregnancy that occurs in a female partner of a male study participant should be reported to the sponsor. Information on this pregnancy will be collected on the Pregnancy Surveillance Form; protocol-required procedures for study discontinuation and follow-up must be performed on the subject unless contraindicated by pregnancy (e.g., X-ray studies); other appropriate pregnancy follow-up procedures should be considered if indicated; in addition, the investigator must report and follow-up on information regarding the course of the pregnancy, including perinatal and neonatal outcome; infants should be followed for a minimum of 8 weeks
