LEVERAGE: This phase 1b/2 trial is evaluating the effectiveness of two targeted therapies (venetoclax and obinutuzumab) in combination with an immunotherapy (lenaliomide) to treat follicular lymphomaA Multicenter, Open Label, Phase Ib/II Study of Lenalidomide, Venetoclax and Obinutuzumab in Patients With Treatment-Naïve Follicular Lymphoma

Clinical summary


Patients eligible to participate in this trial will initially receive 6 cycles of obinutuzumab, venetoclax and lenaliomide. Each cycle consists of 28 days. After the initial treatment, a PET-CT scan will be conducted and depending upon the PET-CT scan results maintenance treatment may be received for up to 2 years. Followup will continue for 3 years after the last enrolled patient has received the induction treatment.

  1. Patient has provided written informed consent.
  2. Patient has histologically confirmed follicular lymphoma WHO grade 1-3A and non-contiguous or bulky (>7cm) stage II and stage III or IV according to Lugano criteria 2014, irrespective of FLIPI score
  3. Patient meets ≥1 Groupe d'Etude des Lymphomes Folliculaires (GELF) criterion for treatment.
  4. Bi-dimensionally measurable disease, with at least one mass lesion ≥ 2 cm in longest diameter.
  5. Male or female age ≥ 18 years at signing consent
  6. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2.
  7. Adequate organ and haematologic function within 10 days prior to registration, defined by:

    • Haemoglobin ≥80g/L
    • ANC ≥1 x 109/L and platelet count ≥75 x 109/L; unless due to marrow infiltration or hypersplenism (in which case ANC ≥ 0.5 x 109/L and platelets ≥ 50 x 109/L)
    • Serum aspartate transaminase (AST) or alanine transaminase (ALT) <2.5 x upper limit of normal (ULN)
    • International normalized ratio >1.5 x ULN for patients not receiving therapeutic anticoagulation
    • Partial thromboplastin time (PTT) or activated PTT (aPTT) ≤1.5 x ULN unless due to the presence of an inhibitor (e.g. lupus anticoagulant)
    • Bilirubin <2.0 x ULN unless due to Gilbert's syndrome, documented liver involvement with lymphoma, or of non-hepatic origin
    • Creatinine clearance ≥50ml/min(Cockcroft-Gault)
  8. Able to comply with protocol requirements and follow-up procedures.
  9. Female patients of childbearing potential (FCBP) must be willing to use two methods of birth control simultaneously or be surgically sterile, or abstain from heterosexual activity for at least 28 days before starting lenalidomide and for the course of the study through to 18 months after the last dose of obinutuzumab, 28 days after the last dose of lenalidomide and 30 days after the last dose of venetoclax, whichever is longer. Patients of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 24 consecutive months (Refer to Appendix 4).
  10. Sexually active males must agree to use a condom during sexual contact with a pregnant female or a female of child-bearing potential (FCBP) for the course of the study through to 18 months after the last dose of obinutuzumab, 28 days after the last dose of lenalidomide and 30 days after the last dose of venetoclax, whichever is longer, even if he has undergone a successful vasectomy.


  1. WHO grade 3B follicular lymphoma, biopsy proven or clinically suspected histologic transformation to diffuse large B-cell lymphoma
  2. Known central nervous system lymphoma or leptomeningeal disease.
  3. 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 curative intent may be included provided they remain in remission without treatment for ≥ 2 years prior to enrollment

  4. Has had prior systemic therapy for follicular lymphoma (with the exception of corticosteroid monotherapy to control disease related symptoms).
  5. Major surgery or a wound that has not fully healed within 4 weeks prior to registration.
  6. Patient is unable to swallow tablets.
  7. Any life-threatening illness, medical condition, or organ system dysfunction which, in the investigator's opinion, could compromise the patient's safety, interfere with the absorption or metabolism of venetoclax or lenalidomide capsules, or put the study outcomes at undue risk.
  8. Known hypersensitivity to any of the study drugs or their components (obinutuzumab, L-histidine, L-histidine hydrochloride monohydrate, Trehalose dehydrate, Poloxamer 188), humanized or murine monoclonal antibodies, xanthine oxidase inhibitors or rasburicase.
  9. Has received the following agents within 7 days prior to registration:

    • Steroid therapy with anti-neoplastic intent (with the exception of ≤7 days of prednisolone or equivalent at doses of ≤100mg daily to control lymphoma symptoms prior to cycle 1 day 1)
    • Strong CYP3A inhibitors (See section 7.10.3)
    • Strong CYP3A inducers (See section 7.10.3)
    • Consumed grapefruit, grapefruit products, Seville oranges (including marmalade containing Seville oranges), or star fruit within 3 days of registration
  10. Has a history of stroke or intracranial hemorrhage within 6 months prior to registration.
  11. Has a known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection (excluding fungal infections of nail beds) at study enrollment.

    Patients who are positive for HCV antibody must be negative for HCV by polymerase chain reaction (PCR) to be eligible for study participation Patients with occult or prior HBV infection (defined as positive total hepatitis B core antibody [HBcAb] and negative HBsAg) may be included if HBV DNA is undetectable. These patients must be willing to receive prophylactic lamivudine or entecavir and undergo monthly DNA testing during (and for 6 months following completion of) treatment.
