Clinical Trial Summary

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).

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.

• Follicular lymphoma (FL)Grade 1, 2, or 3a

• Small lymphocytic lymphoma (SLL)

• Marginal zone lymphoma (MZL)( splenic, nodal, or extranodal)

• 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

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Progression-Free Survival (PFS)		From date of enrollment until the date of first documentation of progression or date of death from any cause, whatever came first, assessed up to 78 months
Secondary	Complete Response (CRR)		Every 3-6 Cycles (each cycle is 28 days) from date of randomization, until date of first documented progression. Subjects will be evaluated for progression through the primary analysis of the study or 5 years from randomization, whichever is later.
Secondary	Overall Response Rate (ORR)		Every 3-6 Cycles (each cycle is 28 days) from date of randomization, until date of first documented progression. Subjects will be evaluated for progression through the primary analysis of the study or 5 years from randomization, whichever is later.
Secondary	Overall Survival (OS)		Every 6 months for up to 5 years from date of randomization
Secondary	Duration of Response (DOR)		Every 3-6 Cycles (each cycle is 28 days) from date of randomization, until date of first documented progression. Subjects will be evaluated for progression through the primary analysis of the study or 5 years from randomization, whichever is later.
Secondary	Safety (Treatment- emergent adverse events (TEAEs) and changes in safety laboratory values)		Continuous from informed consent until 30 days from last dose
Secondary	Pharmacokinetics (PK)	Evaluate the Duvelisib concentration in plasma sample.	Cycle 1 and Cycle 2 (each cycle is 28 days)
Secondary	Pharmacokinetics (PK)	Evaluate IPI-656 (metabolite) concentration in plasma sample.	Cycle 1 and Cycle 2 (each cycle is 28 days)
