Clinical Trial 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.

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Expression of biomarkers using immunohistochemistry and blood samples (Part A)	Descriptive statistics including plots, mean, median and standard deviations will be used to summarize data. For continuous outcomes, t-test and analysis of variance will be used to compare outcome measures across patient characteristics. Pair-wise comparisons will be performed using pre- and post-therapy samples from each patient. The chi-square test or Fisher's exact test will be used to test the association between two categorical variables. Both univariate and multivariate logistic regressions will be performed to model prognostic factors.	Up to time of treatment discontinuation
Primary	Overall response rate: number of participants with response (Part A)	Responses assessed using computed tomography (CT) scans or magnetic resonance imaging according to standard Response Evaluation Criteria In Solid Tumors (RECIST) 1.1 criteria in order to assess disease progression. Complete Response (CR): Disappearance all target lesions; any pathological lymph nodes reduction in short axis to < 10 mm (< 1 cm). Partial Response (PR): > 30% decrease in sum diameters of target lesions. Progressive Disease (PD): > 20% increase in sum diameters lesions. (Note: appearance of one or > new lesions considered progressions). Stable Disease (SD): Neither shrinkage qualify for PR nor increase for PD.	Up to 2 years
Primary	Progression-free survival (PFS) (Part B)		Time period from the date of randomization to the date of PD or death whichever occurred first, assessed up to 2 years
Secondary	Number of participants with toxicities (Part A)	Will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The most frequent of adverse events measured relative to the total number of patients treated, and the toxicities tabulated by grade according to CTCAE.	Up to 100 days post-treatment
Secondary	Overall survival (Part A and B)	Time measured from initiation of treatment with nivolumab till death. Kaplan-Meier analysis will be performed to estimate the median overall survival with a 95% confidence interval.	From initiation of treatment with nivolumab until death, assessed up to 2 years
Secondary	Progression-free Survival (Part A)	From initiation of treatment with nivolumab until the time of disease progression, time measured in months. Kaplan-Meier analysis performed to estimate the median progression-free survival with a 90% confidence interval.	From initiation of treatment with nivolumab until the time of disease progression, assessed up to 2 years
Secondary	Overall response rates (Part B)	Responses assessed using CT scans or magnetic resonance imaging according to standard RECIST 1.1 criteria in order to assess disease progression. CR: Disappearance all target lesions; any pathological lymph nodes reduction in short axis to < 10 mm (< 1 cm). PR: > 30% decrease in sum diameters of target lesions. PD: > 20% increase in sum diameters lesions. (Note: appearance of one or > new lesions considered progressions). SD: Neither shrinkage qualify for PR nor increase for PD.	Up to 2 years
Secondary	Incidence of grade 3/4/5 adverse events (Part B)	Will be assessed by CTCAE version 5.0.	Up to 2 years
