Obinutuzumab, Venetoclax, and Lenalidomide in Treating Patients with Relapsed or Refractory B-cell Non-Hodgkin Lymphoma

Trial Status: Closed to Accrual

This phase I study studies the side effects and best dose of venetoclax and lenalidomide when given together with obinutuzumab in treating patients with B-cell non-Hodgkin lymphoma that has returned after a period of improvement or not responding to treatment. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may induce changes in body’s immune system and may interfere with the ability of tumor cells to grow and spread. Venetoclax may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. 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, venetoclax, and lenalidomide may work better in treating patients with B-cell non-Hodgkin lymphoma.

Exclusion Criteria

  • Patients with active central nervous system (CNS) involvement with lymphoma are not eligible
  • Patients with a known history of human immunodeficiency virus (HIV) or human T-cell leukemia virus 1 (HTLV-1) are not eligible
  • Evidence of active hepatitis B infection, based on positive surface antigen or hepatitis B deoxyribonucleic acid (DNA) polymerase chain reaction (PCR), or active hepatitis C infection; patients who are hepatitis B core antibody positive must take prophylaxis with lamivudine or equivalent and be willing to undergo monthly hepatitis B DNA PCR testing

  • Any chemotherapy or radiation therapy within 4 weeks of the first dose of study drug
  • Patients may take steroids for disease control up to 24 hours prior to study enrollment
  • Any illness, medical condition or organ system dysfunction which, in the investigator’s opinion, could compromise the subject’s safety, interfere with the absorption or metabolism of venetoclax and lenalidomide, or put the study outcomes at undue risk
  • A cardiovascular disability status of New York Heart Association class >= 2
  • History of severe allergic reactions to humanized monoclonal antibodies
  • History of other malignancy that could affect compliance with the protocol or interpretation of results; patients with a history of curatively treated basal or squamous cell carcinoma or stage 1 melanoma of the skin or in situ carcinoma of the cervix are eligible; patients with a malignancy that has been treated with surgery alone with curative intent will also be excluded; individuals in documented remission without treatment for >= 2 years prior to enrollment may be included at the discretion of the investigator
  • Known hypersensitivity to any of the study drugs or analogs
  • Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment, or any major episode of infection requiring treatment with IV antibiotics or hospitalization (relating to the completion of the course of antibiotics) within 4 weeks prior study therapy
  • Requires the use of warfarin (because of potential drug-drug interactions that may potentially increase the exposure of warfarin)
  • Received the following agents within 7 days prior to the first dose of venetoclax: * Strong and moderate CYP3A inhibitors * Strong and moderate CYP3A inducers * Consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges), or star fruit within 3 days prior to the first dose of venetoclax
  • Clinically significant history of liver disease, including viral or other hepatitis, current alcohol abuse, or cirrhosis

I. To determine the dose limiting toxicity (DLT) and the recommended phase 2 dose (RP2D), which is typically the maximum tolerated dose (MTD), of the combination of obinutuzumab, venetoclax, and lenalidomide in patients with relapsed or refractory B-cell non-Hodgkin lymphoma (NHL).


I. To estimate the overall objective response rate to the combination of obinutuzumab, venetoclax, and lenalidomide in patients with relapsed or refractory B-cell NHL.

II. To estimate the duration of response and 2 year progression-free survival associated with obinutuzumab, venetoclax, and lenalidomide treatment in patients with relapsed and refractory B-cell NHL.

III. To define the qualitative and quantitative toxicities of the combination of obinutuzumab, venetoclax, and lenalidomide in patients with relapsed or refractory B-cell NHL.

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

Patients receive lenalidomide orally (PO) on days 1-21 and venetoclax PO on days 1-28. Patients also receive obinutuzumab intravenously (IV) on days 1, 8, and 15 of cycle 1 and on day 1 of cycles 2-6. Treatment repeats every 28 days for up to 12 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up at 4 weeks, every 3 months for 2 years, then every 6 months.
