Ixazomib and Rituximab in Treating Patients With Relapsed or Refractory Mantle Cell Lymphoma

Recurrent Mantle Cell Lymphoma Clinical Trial

Official title: A Phase 2 Study of Ixazomib and Rituximab in Bruton Tyrosine Kinase Inhibitor Resistant Mantle Cell Lymphoma

Status Active, not recruiting

Clinical Trial Summary

This phase II trial studies how well ixazomib and rituximab work in treating patients with mantle cell lymphoma that has come back (relapsed) or does not respond (refractory) to BTK inhibitor treatment. Ixazomib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with rituximab may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving ixazomib and rituximab may work better in treating patients with mantle cell lymphoma compared to rituximab alone.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To evaluate the complete remission rate of Bruton's tyrosine kinase (BTK) inhibitor refractory mantle cell lymphoma (MCL) patients with ixazomib citrate (ixazomib) and rituximab at 16 weeks of therapy.

SECONDARY OBJECTIVES:

I. To evaluate overall response rate (ORR) assessed by Lugano criteria. II. To evaluate progression free survival (PFS) and overall survival (OS). III. To evaluate the safety and tolerability.

TERTIARY/EXPLORATORY OBJECTIVES:

I. To evaluate biomarkers of response to treatment and mechanisms of resistance with pretreatment and post-treatment bone marrow and blood samples with deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) sequencing and immune profiling by flow cytometry.

OUTLINE:

Patients receive ixazomib orally (PO) on days 1, 8, and 15. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive rituximab intravenously (IV) over 4-8 hours on days 1, 8, 15, and 22 of cycle 1. Beginning in cycle 3, patients receive rituximab IV over 4-8 hours on day 1. Treatment repeats every 28 days up to cycle 12 in the absence of disease progression or unacceptable toxicity. Patients benefiting from treatment may continue to receive ixazomib indefinitely in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically. ;
