Brief Summary

This phase II trial studies how well obinutuzumab and lenalidomide work in treating patients with previously untreated stage II-IV grade 1-3a follicular lymphoma. Immunotherapy with obinutuzumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving obinutuzumab and lenalidomide may work better in treating patients with previously untreated follicular lymphoma.

Detailed Description

PRIMARY OBJECTIVES:

I. To evaluate the efficacy of obinutuzumab combined with lenalidomide in patients with previously untreated follicular lymphoma (FL) (determined by progression-free survival \[PFS\] at 2 years).

SECONDARY OBJECTIVES:

I. To evaluate the safety of obinutuzumab in combination with lenalidomide in patients with untreated follicular lymphoma.

II. To evaluate the efficacy of obinutuzumab in combination with lenalidomide in subjects with follicular lymphoma as assessed by complete remission (CR) at 30 months, overall response rate (ORR), duration of response (DOR), event free survival (EFS), and overall survival (OS).

EXPLORATORY OBJECTIVES:

I. To evaluate prognostic and predictive biomarkers relative to treatment outcomes.

OUTLINE:

Patients receive obinutuzumab intravenously (IV) over 4-6 hours on days 1, 8, and 15 of course 1 and day 1 of courses 2-6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30. Treatment repeats every 28 days for up to 30 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive lenalidomide orally (PO) on days 1-21. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients with CR or complete remission unconfirmed (CRu) may receive up to an additional 12 courses of lenalidomide.

After completion of study treatment, patients are followed up every 6 months for 18 months and then every year for up to 2 years.
