Ibrutinib and Rituximab in Treating Patients With Relapsed or Refractory Mantle Cell Lymphoma or Older Patients With Newly Diagnosed Mantle Cell Lymphoma

Mantle Cell Lymphoma Clinical Trial

Official title: A Phase II Study of Ibrutinib Plus Rituximab in Patients With Relapsed/Refractory Mantle Cell Lymphoma or Elderly Patients With Newly Diagnosed MCL

Status Active, not recruiting

Clinical Trial Summary

This phase II trial studies how well ibrutinib and rituximab work in treating patients with mantle cell lymphoma that has come back or has not responded to treatment or older patients with newly diagnosed mantle cell lymphoma. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as rituximab, may find cancer cells and help kill them. Giving ibrutinib and rituximab may be an effective treatment for mantle cell lymphoma.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To evaluate the response rate of ibrutinib plus rituximab in patients with relapsed and/or refractory mantle cell lymphoma (MCL).

II. To evaluate the safety and response rate of ibrutinib plus rituximab in elderly patients (> 65) with newly-diagnosed, untreated MCL.

SECONDARY OBJECTIVES:

I. To further evaluate the toxicity profile of the combination of ibrutinib and rituximab in patients with relapsed and/or refractory MCL.

II. To estimate the overall response rate (ORR); (partial response [PR] or better), the response duration (DOR), progression-free survival (PFS), time to progression (TTP) and overall survival (OS) in patients with relapsed and/or refractory MCL; clinical benefit response (CBR) = (minimal response [MR] + ORR) will also be evaluated.

III. To estimate the response duration, PFS, time to progression (TTP), and OS in elderly patients (> 65) with newly-diagnosed, untreated MCL.

EXPLORATORY OBJECTIVES:

I. To correlate detected gene mutations and changes in gene and/or protein expression with response to treatment.

OUTLINE:

Patients receive ibrutinib orally (PO) daily on days 1-28 and rituximab intravenously (IV) over 4-8 hours on days 1, 8, 15, and 22 of course 1; on day 1 of courses 3-8; and on day 1 of every other course for all subsequent courses. Treatment with rituximab repeats every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. Courses with ibrutinib repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 1 year and then every 6 months thereafter. ;
