Ibrutinib and Venetoclax in Treating Patients with Relapsed or Refractory Follicular Lymphoma

Trial Status: Active

This phase I / II trial studies the side effects and best dose of ibrutinib and venetoclax and to see how well they work in treating patients with follicular lymphoma that has returned after a period of improvement or does not respond to treatment. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Venetoclax may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving ibrutinib and venetoclax may work better in treating patients with follicular lymphoma.

  • Concurrent systemic immunosuppressant therapy (e.g., cyclosporine A, tacrolimus, etc., or chronic administration [> 14 days] of > 20 mg/day of prednisone) within 28 days of the first dose of study drug
  • Undergone an allogeneic stem cell transplant within the past 1 year
  • Current or history of graft versus host disease
  • Vaccinated with live, attenuated vaccines within 4 weeks of first dose of study drug
  • Recent infection requiring systemic treatment that was completed =< 14 days before the first dose of study drug

  • Known bleeding disorders (e.g., von Willebrand’s disease) or hemophilia
  • History of stroke or intracranial hemorrhage within 6 months prior to enrollment
  • Known human immunodeficiency virus (HIV) infection
  • Active infection with hepatitis C virus (HCV) or hepatitis B virus (HBV) * Subjects who are positive for hepatitis B core antibody, hepatitis B surface antigen, hepatitis C antibody, must have a negative polymerase chain reaction (PCR) result for the respective disease before enrollment; those who are PCR positive will be excluded
  • Any uncontrolled active systemic infection

PRIMARY OBJECTIVES:

I. To determine the recommended phase II doses of ibrutinib and venetoclax for combination in relapsed and refractory follicular lymphoma. (Phase I)

II. To determine the efficacy of ibrutinib and venetoclax when combined in relapsed and refractory follicular lymphoma. (Phase II)

SECONDARY OBJECTIVES:

I. To determine the pharmacokinetics of ibrutinib and venetoclax when dosed in combination in relapsed and refractory follicular lymphoma. (Phase I)

II. To determine the safety and tolerability of ibrutinib and venetoclax when combined in relapsed and refractory follicular lymphoma. (Phase II)

EXPLORATORY OBJECTIVES:

I. To evaluate mutations of resistance via next-generation sequencing to the regimen when administered in combination in relapsed and refractory follicular lymphoma.

II. To evaluate for an association between BCL-2 and other family member protein levels of expression and efficacy of the regimen.

III. To evaluate the feasibility of developing tumor cell cultures from bone marrow aspirates with lymphomatous involvement in order to better characterize activity of the combination.

OUTLINE: This is a phase I, dose-escalation study followed by a phase II study.

Patients receive ibrutinib orally (PO) once daily (QD) and venetoclax PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 6 or 12 months for up to 10 years.
