Description

Summary

This phase II trial studies how well obinutuzumab, ibrutinib, and venetoclax work in treating patients with previously untreated stage II-IV 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. Ibrutinib and venetoclax may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving obinutuzumab, ibrutinib, and venetoclax together may work better in treating follicular lymphoma compared to each drug alone.

Official Title

A Phase II Trial of the Combination of Obinutuzumab, Ibrutinib, and Venetoclax in Patients With Previously Untreated Follicular Lymphoma

Details

PRIMARY OBJECTIVE:

  1. To evaluate the efficacy of obinutuzumab combined with venetoclax and ibrutinib in patients with previously untreated follicular lymphoma (FL) (determined by a positron emission tomography [PET]/computed tomography [CT] complete response [CR] rate at 12 months as per International Workshop Lymphoma Response Criteria, Cheson 2014).

SECONDARY OBJECTIVES:

  1. To evaluate the safety and tolerability of obinutuzumab in combination with venetoclax and ibrutinib in patients with untreated FL as assessed by frequency, severity, and relatedness of treatment-emergent adverse events (AEs) as well as frequency of treatment-emergent AEs requiring discontinuation or dose reduction of study drug.

II. To evaluate the efficacy of obinutuzumab in combination with venetoclax and ibrutinib in subjects with untreated FL as assessed by CR at 30 months, overall response rate (ORR) (CR + partial response [PR]), duration of response (DOR), time to next anti-lymphoma treatment (TTNT), progression-free survival (PFS), and OS.

OUTLINE:

Patients receive obinutuzumab intravenously (IV) over 60 minutes on days 1, 8, and 15 of cycle 1, day 1 of cycles 2-6, 8, 10, 12, 14, 16, 18, 20, 22, and 24. Patients also receive venetoclax orally (PO) once daily (QD) on days 1-28 (days 4-28 of cycle 1) and ibrutinib PO QD on days 1-28. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically for up to 2 years.

Eligibility

You can join if…

Open to people ages 18 years and up

  • A diagnosis of follicular lymphoma (grades 1, 2, or 3a), untreated
  • Able and willing to provide written informed consent and to comply with the study protocol
  • Bi-dimensionally measurable disease, with at least one mass lesion >= 2 cm in longest diameter by CT, PET/CT, and/or magnetic resonance imaging (MRI)
  • Must be in need of therapy as evidenced by at least one of the following criteria:
  • Bulky disease defined as:
  • A nodal or extranodal (except spleen) mass > 7 cm in its greater diameter or,
  • At least 3 nodal or extranodal sites >= 3 cm in diameter
  • Presence of at least one B symptom:
  • Fever (> 38 Celsius [C]) not due to infectious etiology
  • Night sweats
  • Weight loss > 10% in the past 6 months
  • Fatigue due to lymphoma
  • Splenomegaly (> 13 cm)
  • Compression syndrome (ureteral, orbital, gastrointestinal)
  • Any of the following cytopenias, due to lymphoma:
  • Hemoglobin =< 10 g/dL
  • Platelets =< 100 x 109/L

  • Absolute neutrophil count (ANC) < 1.5 x 109/L

  • Pleural or peritoneal effusion
  • Lactate dehydrogenase (LDH) > upper limit of normal (ULN) or beta (B)2 microglobulin > ULN
  • Other lymphoma-mediated symptoms as determined by the treating physician
  • Stage II, III, or IV disease
  • Eastern Cooperative Oncology Group (ECOG) performance status =< 2
  • Absolute neutrophil count (ANC) > 1.0 x 109/L

  • Platelet count > 50 x 109/L

  • Prothrombin time (PT)/international normal ratio (INR) < 1.5 x (upper limit of normal) ULN and partial thromboplastin time (PTT) (activated partial thromboplastin time [aPTT]) < 1.5 x ULN (unless abnormalities are unrelated to coagulopathy or bleeding disorder). When treated with warfarin or other vitamin K antagonists, then INR =< 3.0)
  • Serum aspartate transaminase (AST) and alanine transaminase (ALT) < 3 x upper limit of normal (ULN)
  • Creatinine clearance > 30 ml/min calculated by modified Cockcroft-Gault formula
  • Bilirubin < 1.5 x ULN unless bilirubin is due to Gilbert's syndrome, documented liver involvement with lymphoma, or of non-hepatic origin, in which case bilirubin should not exceed 3 g/dL

Females of childbearing potential must either completely abstain from heterosexual sexual contact or must use 2 methods of reliable contraception. Reliable contraceptive methods include 1 highly effective method (intrauterine device, birth control pills, hormonal patches, injections, vaginal rings, or implants) and at least 1 additional method (condom, diaphragm, or cervical cap) every time they have sex with a male. Males who are sexually active must be practicing complete abstinence or agree to a condom during sexual contact with a pregnant female or female of child bearing potential. Men must agree to not donate sperm during and for 90 days after the last dose of study drug
