About

This phase I trial studies the safety and how effective the combination of ublituximab, umbralisib, and lenalidomide is in certain types of indolent (slow-growing) non-Hodgkin's lymphoma or mantle cell lymphoma. Lenalidomide may stimulate the immune system in different ways and stop cancer cells from growing. Lenalidomide may also stop the growth of non-Hodgkin's lymphoma by blocking blood flow to the cancer. Umbralisib is designed to block a protein called PI3 kinase in order to stop cancer growth and cause changes in the immune system that may allow the immune system to better act against cancer cells. Ublituximab is an antibody that attaches to the lymphoma cells and triggers immune reactions that may result in the death of the targeted lymphoma cells.

Full description

PRIMARY OBJECTIVE:

I. Determine the recommended phase 2 dose (RP2D) and toxicity of lenalidomide, umbralisib and ublituximab in patients with relapsed or refractory indolent non-Hodgkin lymphoma (iNHL) or mantle cell lymphoma (MCL).

SECONDARY OBJECTIVES:

I. Determine the overall response rate (ORR) for patients with relapsed or refractory follicular lymphoma (FL) treated at the RP2D.

II. Determine duration of response (DOR), progression-free survival (PFS), time to treatment failure and overall survival (OS) for patients with relapsed or refractory FL treated at the RP2D.

OUTLINE: This is a dose-escalation study of lenalidomide and umbralisib.

Patients receive lenalidomide orally (PO) once daily (QD) on days 1-21 and umbralisib PO QD on days 1-28. Beginning in cycle 2, patients also receive ublituximab intravenously (IV) over 90 minutes to 4 hours on day 1. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients who achieve a partial or complete response after cycle 6 continue treatment of lenalidomide PO QD and umbralisib PO QD for 12 additional cycles, and ublituximab IV on day 1 of subsequent even cycles (8, 10, 12, 14, 16, and 18). Patients with stable disease after cycle 6 may continue on treatment for an additional 12 cycles at the discretion of the investigator.

After completion of study treatment, patients are followed up within 8 weeks, and then every 6 months for 2 years.

Subjects with positive HBc antibody and negative HBV DNA by PCR are eligible. Subjects with positive HCV antibody and negative HCV RNA by PCR are eligible. Subjects who are CMV IgG or CMV IgM positive but who are CMV DNA negative by PCR are eligible
• Pregnant or breastfeeding women are excluded from this study because lenalidomide has known teratogenic effects. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with lenalidomide, breastfeeding should be discontinued if the mother is treated with lenalidomide. These potential risks may also apply to other agents used in this study
• History of anaphylaxis (excluding infusion related reactions) in association with previous anti-CD20 administration
