Clinical Trial Summary

This phase II trial compares the safety, side effects and effectiveness of anti-lag-3 (relatlinib) and anti-PD-1 blockade (nivolumab) to standard of care lomustine for the treatment of patients with glioblastoma that has come back after a period of improvement (recurrent). Relatlimab and nivolumab are monoclonal antibodies that may interfere with the ability of tumor cells to grow and spread. Lomustine is a chemotherapy drug and in a class of medications called alkylating agents. It damages the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. Relatlinib and nivolumab may be safe, tolerable, and/or effective compared to standard of care lomustine in treating patients with recurrent glioblastoma.

Clinical Trial Description

PRIMARY OBJECTIVE:

I. To compare the restricted mean survival time (RMST) for overall survival (OS) between patients receiving the combination of relatlimab (BMS-986016) and nivolumab versus patients receiving standard of care chloroethylcyclohexylnitrosourea (CCNU) (lomustine).

SECONDARY OBJECTIVES:

I. To compare the 12-month OS rates between patients receiving the combination of relatlimab (BMS-986016) and nivolumab versus patients receiving standard of care CCNU (lomustine).

II. To compare the restricted mean survival times for progression-free survival (PFS) between patients receiving the combination of relatlimab (BMS-986016) and nivolumab versus patients receiving standard of care CCNU (lomustine).

III. To compare the radiographic response rate between patients receiving the combination of relatlimab (BMS-986016) and nivolumab versus patients receiving standard of care CCNU (lomustine).

IV. To compare the safety/adverse event rate between patients receiving the combination of relatlimab (BMS-986016) and nivolumab versus patients receiving standard of care CCNU (lomustine).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive nivolumab intravenously (IV) over 30 minutes followed by relatlimab IV over 30 minutes on day 1 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo magnetic resonance imaging (MRI) at baseline and every 8 weeks until progression and then at least 8 weeks after objective response. Additionally patients undergo surgery or biopsy and blood sample collection throughout study.

ARM II: Patients receive lomustine orally (PO) on day 1 of each cycle. Cycles repeat every 42 days in the absence of disease progression or unacceptable toxicity. Patients also undergo MRI every 9 weeks until progression and then at least 6 weeks after objective response. Additionally patients undergo surgery or biopsy and blood sample collection throughout study.

After completion of study treatment, patients are followed up every 6 months for up to 5 years from time of randomization. ;
