This was a long-term, continued treatment study that evaluated the long-term safety, clinical activity, and overall survival (OS) of duvelisib in individuals with hematologic malignancies that were previously treated with duvelisib in a previous sponsor-approved study.

Study IPI-145-23 was an international, multicenter, open-label, single-arm, Phase 2 study designed to evaluate the long-term safety, clinical activity, and overall survival data of duvelisib in individuals with hematologic malignancies. Only individuals who have participated in a previous duvelisib study that were approved by the sponsor were allowed to enroll in the study.

Participants in active treatment and participants in survival follow-up were allowed to rollover to this study. For participants on active treatment, participants continued the same dose from their previous duvelisib study administered twice daily for 28-day continuous cycles until disease progression or unacceptable toxicity and then followed in a survival follow-up period. For participants in survival follow-up, participants continued to be followed-up for survival in this study for the duration as outlined in their previous duvelisib study.

Inclusion Criteria:

• Have participated in a previous study of duvelisib, and:

  • Be actively receiving duvelisib monotherapy on the previous study (within 14 days of study entry) and demonstrating clinical benefit (complete response [CR]/ partial response [PR]/ stable disease [SD]) of continued use, or
  • Be in the survival follow-up phase of a previous duvelisib study

• Have completed the required components of the previous study and be appropriate for enrollment into this long-term continued treatment and follow-up study, as determined by the Sponsor

Exclusion Criteria:

• Had any ongoing ≥ Grade 3 adverse event (AE) considered related to duvelisib treatment at screening
• Was pregnant or nursing
