Obinutuzumab With or Without Umbralisib, Lenalidomide, or Combination Chemotherapy in Treating Patients With Relapsed or Refractory Grade I-IIIa Follicular Lymphoma

• Status: Recruiting
• Trial end date: 2022-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This phase II trial studies how well obinutuzumab with or without umbralisib, lenalidomide, or combination chemotherapy work in treating patients with grade I-IIIa follicular lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Immunotherapy with obinutuzumab, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Umbralisib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Drugs used in chemotherapy, such as cyclophosphamide, doxorubicin, vincristine, prednisone, and bendamustine, 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. It is not yet known whether giving obinutuzumab with or without umbralisib, lenalidomide, or combination chemotherapy will work better in treating patients with grade I-IIIa follicular lymphoma.

• Patients must have either failed to achieve a complete remission, or must have relapsed within 2 years after completing CHOP or bendamustine-containing chemoimmunotherapy (including an anti-CD20 monoclonal antibody), as measured from the last dose of CHOP or bendamustine; relapsed patients must not have received any intervening chemotherapy

• Patients must have received only 1 course of chemotherapy, containing at least 3 cycles of CHOP or bendamustine; (note that no minimum dose of bendamustine is required)

• Patients who received any anti-CD20 antibody therapy prior to CHOP or bendamustine are eligible

• Patients who additionally received any maintenance anti-CD-20 antibody therapy or consolidative radioimmunotherapy within 2 years of the last dose of the CHOP or bendamustine therapy are eligible

• Involved field or involved site radiation is not considered a line of therapy; examples of eligible prior treatment regimens (note this list is not all inclusive):

• 1st line rituximab treatment followed years later by bendamustine rituximab x 4 cycles

• Bendamustine rituximab x 4 cycles

• 1st line rituximab treatment, 2nd line ibritumomab tiuxetan, followed by bendamustine bortezomib rituximab x 6 cycles followed by rituximab maintenance

• Bendamustine obinutuzumab x 3 cycles

• CHOP rituximab x 6 cycles followed by rituximab maintenance

• For all forms of systemic therapy, patients must have completed therapy at least 21 days prior to registration; patients must have completed any radioimmunotherapy at least 84 days prior to registration; patients must have recovered from all treatment related toxicities from these therapies prior to registration

• Patients must have adequate renal function as documented by a calculated creatinine clearance >= 60 mL/min, within 28 days prior to registration

• Total bilirubin =< 1.5 x institutional upper limit of normal (IULN) (=< 5 x IULN if secondary to lymphoma, Gilbert's syndrome, or medication related [e.g., indinavir, tenofovir, atazanavir]) within 28 days prior to registration

• Direct bilirubin =< 1.5 x IULN (=< 5 x IULN if secondary to lymphoma) within 28 days prior to registration

• Patients must have an echocardiogram (ECHO) or multigated acquisition (MUGA) scan within 42 days prior to registration with a cardiac ejection fraction >= 45%

• Patients with hepatitis B virus infection must have undetectable hepatitis B virus (HBV) on suppressive therapy and no evidence of HBV-related hepatic damage; patients with hepatitis C virus infection are eligible if complete eradication therapy has been successfully completed, and there is no detectable hepatitis C virus (HVC) or related hepatic damage; patients with known human immunodeficiency virus (HIV) infection are eligible if they meet all of the following criteria in addition to the other protocol eligibility criteria:

• Patient must have no history of acquired immune deficiency syndrome (AIDS)-related complications, other than a history of low CD4+ T-cell count (< 200/mm^3) prior to initiation of combination antiretroviral therapy; on study CD4+ T-cell count may not be informative due to leukemia and should not be used as an exclusion criterion if low

• Patient must be healthy on the basis of HIV disease with high likelihood of near normal life span were it not for the leukemia

• Patient must have serum HIV viral load of < 200 copies/mm^3

• Patient must be on combination antiretroviral therapy with minimal pharmacokinetic interactions with study therapy and minimal overlapping clinical toxicity with protocol therapy; (recommend a regimen of the integrase inhibitor dolutegravir combined with either disoproxil fumarate/emtricitabine or dolutegravir combined with tenofovir alafenamide/emtricitabine)
