A Study of Duvelisib and Venetoclax in Subjects With Relapsed or Refractory Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or Indolent or Aggressive Non-Hodgkin Lymphoma, Who Have Not Previously Received a Bcl-2 or PI3K Inhibitor

A Phase 1b/2 Study of Duvelisib and Venetoclax in Subjects With Relapsed or Refractory Chronic Lymphocytic Leukemia, Small Lymphocytic Lymphoma, or Indolent or Aggressive Non-Hodgkin Lymphoma, Who Have Not Previously Received a Bcl-2 or PI3K Inhibitor

This study is designed to assess the safety, pharmacokinetics, drug-drug interactions, and determine the recommended Phase 2 doses of co administered Duvelisib and Venetoclax in participants with relapsed or refractory chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma, or indolent or aggressive non-Hodgkin lymphoma, who have not previously received a Bcl-2 or Phosphoinositide 3-kinase (PI3K) inhibitor. The Phase 2 portion of the study will preliminarily evaluate efficacy, and expand the toxicity evaluation.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Duvelisib+Venetoclax	Drug: Duvelisib; Duvelisib will be taken continuously. This is a defining dose study, therefore the dose of Duvelisib may change.; Drug: Venetoclax; Venetoclax will be taken continuously. This is a defining dose study, therefore the dose of Venetoclax will change.
