Study did not meet first stage requirements of interim analysis

The primary objective will be to assess overall response rate of nivolumab in patients with metastatic or locally advanced adrenocortical carcinoma. Nivolumab was recently approved by U.S. Food and Drug Administration (FDA) for the treatment of advanced melanoma, non-small cell lung cancer and renal cell carcinoma. It is considered investigational for the treatment of advanced or refractory adrenocortical carcinoma. "Investigational" means that the drug is not approved by the USFDA or not approved for the indication under investigation. Nivolumab could shrink adrenocortical carcinoma but it could also cause side effects. Researchers hope to learn if the study drug will shrink the cancer and hopefully to relieve symptoms that are related to the cancer.

PRIMARY OBJECTIVES:

I. To assess overall response rate of nivolumab in patients with metastatic or locally advanced adrenocortical carcinoma (ACC).

SECONDARY OBJECTIVES:

I. To assess the progression free survival defined as time from date of first nivolumab infusion until date of death or evidence of progression of disease as assessed by computed tomography (CT) imaging every 8 weeks according to Response Evaluation Criteria in Solid Tumors (RECIST) criteria 1.1.

II. To assess the overall survival defined as time from date of first nivolumab infusion until death of patients with metastatic or locally advanced ACC.

III. To assess the safety and tolerability profile of nivolumab described by number, frequency, and severity of adverse events according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 4.0.3 assessed every 2 weeks while patients are on therapy.

TERTIARY OBJECTIVES:

I. To assess the overall response rate, progression free survival and overall survival according to tumor programmed cell death 1 ligand 1 (PD-L1) and programmed cell death 1 ligand 2 (PD-L2) expression.

II. To assess the overall response rate, progression free survival and overall survival according to serum interleukin levels and peripheral T cell profile levels.

III. To measure humoral and cellular responses to tumor antigens on serum samples by measuring the levels of cytokines (ie, interleukin [IL] -2, IL-6, IL-8, IL-10, IL-18, interferon [IFN] gamma and tumor necrosis factor [TNF]-alpha) and peripheral blood lymphocyte phenotype.

OUTLINE:

Patients receive nivolumab intravenously (IV) over 30 minutes every 2 weeks in the absence of disease progression or unacceptable toxicity, or withdrawal of consent.

• Serum creatinine of < 3.0 x ULN (upper limit of normal) or creatinine clearance (CrCl) > 30 mL/minute (using Cockcroft/Gault formula below)
• Patients with history of central nervous system (CNS) metastases are eligible if CNS disease has been radiographically and neurologically stable for at least 6 weeks prior to study registrations and do not require corticosteroids (of any dose) for symptomatic management
• Females of childbearing potential (FOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [HCG]) within 72 hours prior to the start of study drug; NOTE: a FOCBP is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria: has not undergone a hysterectomy or bilateral oophorectomy; has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months)
• FOCBP must agree to follow instructions for method(s) of contraception (e.g. hormonal or barrier method of birth control; abstinence) for the duration of treatment with nivolumab plus 5 half-lives of nivolumab (19 weeks) plus 30 days (duration of ovulatory cycle) for a total of 23 weeks post-treatment completion
• Males who are sexually active with women of childbearing potential (WOCBP) must agree to follow instructions for method(s) of contraception (e.g. hormonal or barrier method of birth control; abstinence) for the duration of treatment with nivolumab plus 5 halflives of the study drug (19 weeks) plus 90 days (duration of sperm turnover) for a total of 31 weeks days post-treatment completion

• Patients who have a history of allergic reactions attributed to compounds of similar chemical or biologic composition to nivolumab are not eligible

• Patients should be excluded if they have had prior treatment with an anti-PD1 or anti-PD-L1. Please contact principal investigator, Benedito Carneiro, for specific questions on potential interactions
