Recurrent Mantle Cell Lymphoma Refractory Mantle Cell Lymphoma | Drug: Ixazomib Drug: Ixazomib Citrate Biological: Rituximab | Phase 2 |
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.

Experimental: Treatment (ixazomib, rituximab)
Patients receive ixazomib by mouth 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 IV over 4-8 hours on days 1, 8, 15, and 22 of cycle 1. Beginning in cycle 3, patients receive rituximab Intravenous 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.

- Complete remission rate of BTK inhibitor refractory mantle cell lymphoma patients with ixazomib and rituximab [ Time Frame: At 16 weeks ]
- Overall response rate [ Time Frame: At 16 weeks ]Assessed by Lugano criteria. Overall response and complete response at each of the pre-specified time points will be described as percentage with exact ninety-five percent (95%) confidence interval based on binomial distribution.
- Progression free survival (PFS) [ Time Frame: From the start date of treatment to the date of progression or death due to any cause whichever happened first, assessed up to 1 year ]PFS curves will be described using Kaplan-Meier methods. The curves will be presented with 95% confidence intervals.
- Overall survival (OS) [ Time Frame: From the start date of treatment to death date, assessed up to 1 year ]OS curves will be described using Kaplan-Meier methods. The curves will be presented with 95% confidence intervals.
- Incidence of toxicities [ Time Frame: Up to 56 weeks ]Toxicities will be measured using Common Terminology Criteria for Adverse Events version 4.0. The maximum grade of each toxicity will be described in tabular form as count and percentages.
- Biomarkers of response to treatment [ Time Frame: Up to 56 weeks ]Will be measured with pre-treatment and post-treatment bone marrow and blood samples with deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) sequencing and immune profiling by flow cytometry.
- Mechanisms of resistance [ Time Frame: Up to 56 weeks ]Will be measured with pre-treatment and post-treatment bone marrow and blood samples with DNA and RNA sequencing and immune profiling by flow cytometry.
