About

This study will evaluate the efficacy and safety of duvelisib in combination with bendamustine and rituximab (DBR) vs placebo in combination with bendamustine and rituximab (PBR) in subjects with previously-treated indolent non-Hodgkin lymphoma (iNHL).

Full description

Study IPI-145-22 is an international, multicenter, randomized, double-blind, placebo-controlled, two-arm Phase 3 study designed to evaluate efficacy and safety of DBR vs PBR in subjects with previously-treated iNHL (including follicular lymphoma [FL], small lymphocytic lymphoma [SLL] and marginal zone lymphoma [MZL]).

Approximately 600 subjects will receive 25 mg of duvelisib or placebo, orally BID for 28 day continuous cycles, in combination with 375 mg/m2 of rituximab given on Day 1 of Cycles 1-6 and 90 mg/m2 of bendamustine given on Day 1 and Day 2 of Cycles 1-6. Subjects will receive duvelisib until disease progression or unacceptable toxicity.

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

  • Follicular lymphoma (FL)Grade 1, 2, or 3a
  • Small lymphocytic lymphoma (SLL)
  • Marginal zone lymphoma (MZL)( splenic, nodal, or extranodal)

• Have received the following systemic treatments for iNHL:

  • an anti-CD20 antibody; and
  • chemotherapy

• At least 1 measurable disease lesion > 1.5 cm in at least one dimension by computed tomography (CT)/CT-PET or magnetic resonance imaging (MRI)

• Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2 (corresponds to Karnofsky Performance Status [(KPS) ≥60%])

Exclusion criteria

• Clinical evidence of transformation to a more aggressive subtype of lymphoma or grade 3B FL

• Refractory to bendamustine + rituximab therapy or single-agent bendamustine 120 mg/m2, with refractory defined as:

• Infection with hepatitis B, hepatitis C, or human immunodeficiency virus (HIV).

• History of tuberculosis treatment within the two years prior to randomization

• History of chronic liver disease, veno-occlusive disease, or alcohol abuse

• Ongoing treatment with chronic immunosuppressants (e.g., cyclosporine) or systemic steroids > 20 mg of prednisone (or equivalent) daily (QD)

• Ongoing treatment for systemic bacterial, fungal, or viral infection at screening

• Unable to receive prophylactic treatment for pneumocystis, herpes simplex virus (HSV), or herpes zoster (VZV) at screening

• Concurrent active malignancy other than adequately treated non-melanoma skin cancer or lentigo maligna without evidence of invasive disease or adequately treated cervical carcinoma in situ without evidence of disease

• History of stroke, unstable angina, myocardial infarction, or ventricular arrhythmia requiring medication or a pacemaker within the last 6 months prior to screening

• History of progressive multifocal leukoencephalopathy
