Nivolumab and Ibrutinib in Treating Patients With Relapsed or Refractory Central Nervous System Lymphoma

Phase 2

Completed

• Conditions: Recurrent Central Nervous System Lymphoma; Refractory Central Nervous System Lymphoma; Central Nervous System B-Cell Non-Hodgkin Lymphoma
• Interventions: Drug: Ibrutinib; Biological: Nivolumab

• Registration Number: NCT03770416
• Lead Sponsor: M.D. Anderson Cancer Center

Brief Summary

This phase II trial studies the side effects and how well nivolumab and ibrutinib works in treating patients with central nervous system lymphoma that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ibrutinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving nivolumab and ibrutinib may work better in treating patients with central nervous system lymphoma.

Detailed Description

PRIMARY OBJECTIVES:

I. Determine the overall response rate of nivolumab and ibrutinib in central nervous system (CNS) lymphoma.

SECONDARY OBJECTIVES:

I. Determine the overall response rate of 4 weeks of ibrutinib single agent in CNS lymphoma.

II. Determine the complete response rate of nivolumab and ibrutinib in CNS lymphoma.

III. Determine the 1-year progression free and overall survival outcomes in CNS lymphoma.

IV. Safety and toxicity of nivolumab and ibrutinib.

EXPLORATORY OBJECTIVES:

I. Assess activation of T cells in peripheral blood and cerebrospinal fluid. II. Assess the cytokine profile from microglial cells in cerebrospinal fluid. III. Correlate features of peripheral blood T cell activation with toxicities. IV. Correlate features of peripheral blood T cell activation with response and progression free survival (PFS).

V. Correlate baseline tumor characteristics with response and PFS. VI. Evaluate the ability of minimal residual disease testing to monitor response and differentiate from pseudo progression.

OUTLINE: Patients are assigned to 1 of 2 cohorts.

COHORT A: Patients receive ibrutinib orally (PO) daily on days 1-28. Beginning course 1, patients also receive nivolumab intravenously (IV) over 1 hour on days 1 and 15. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

COHORT B: Patients receive ibrutinib PO daily on days 1-28 and nivolumab IV over 1 hour on days 1 and 15. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.

Patients who achieve at least a partial response after 6 courses may continue therapy for up to 2 years.

After completion of study treatment, patients are followed up within 3-4 weeks and then every 3 months for 2 years.

Exclusion Criteria

1. History of another primary invasive malignancy that has not been definitively treated or in remission for at least 2 years. Patients with non-melanoma skin cancers or with carcinomas in situ are eligible regardless of the time from diagnosis (including concomitant diagnoses). If patients have another malignancy that was treated within the last 2 years, such patients may be enrolled if the likelihood of requiring systemic therapy for this other malignancy within 2 years is less than 10%, as determined by an expert in that particular malignancy at MD Anderson Cancer Center and after consultation with the Principal Investigator
2. Any major surgery or wound that has not healed, radiotherapy, cytotoxic chemotherapy, biologic therapy, immunotherapy, immunomodulatory drugs, experimental therapy within 4 weeks prior to the first dose of the study drugs.
