Brief Summary: This phase II trial compares the effect of giving cabozantinib with or without cemiplimab in patients with adrenocortical cancer that has spread to nearby tissue or lymph nodes (locally advanced), and that cannot be removed by surgery (unresectable) or that has come back after a period of improvement (recurrent) or that has spread from where it first started (primary site) to other places in the body (metastatic). Cabozantinib is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply, which may help keep cancer cells from growing. Immunotherapy with monoclonal antibodies, such as cemiplimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib with cemiplimab may kill more tumor cells in patients with locally advanced unresectable or recurrent/metastatic adrenocortical cancer.
Detailed Description: PRIMARY OBJECTIVE:
I. To determine whether the combination of cabozantinib plus cemiplimab (REGN2810) (Cabo-Cemiplimab \[REGN2810\]) improves progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors (RECIST) version (v.) 1.1 relative to cabozantinib alone in patients with locally advanced unresectable or recurrent/metastatic advanced adrenocortical cancer.
SECONDARY OBJECTIVES:
I. To assess tolerability and adverse events of Cabo-Cemiplimab (REGN2810) in advanced adrenocortical cancer (ACC) patients.
II. To assess objective response rate as per RECIST v 1.1. III. To assess duration of objective response, time to progression (TTP), and overall survival (OS) in ACC patients receiving Cabo-Cemiplimab (REGN2810).
EXPLORATORY OBJECTIVE:
I. To assess PFS from re-registration (per RECIST 1.1) and OS for patients who crossover to receive Cabo-Cemiplimab after progressing on cabozantinib alone.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM A: Patients receive cabozantinib orally (PO) once daily (QD) on days 1-21 of each cycle. Cycles repeat every 21 days for 2 years in the absence of disease progression or unacceptable toxicity. Patients undergo computed tomography (CT) scan or magnetic resonance imaging (MRI) and blood sample collection throughout the study. Upon disease progression, patients may elect to crossover to receive combination therapy on Arm B.
ARM B: Patients receive cemiplimab intravenously (IV) over 30 minutes on day 1 and cabozantinib PO QD on days 1-21 of each cycle. Cycles repeat every 21 days for 2 years in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan or MRI and blood sample collection throughout the study.
After completion of study treatment, patients are followed up every 12 weeks until disease progression and then every 6 months for 4 years post-registration.
