Summary
Brief summary (as posted)
The primary objective of this study is to evaluate the safety of entospletinib in combination with vincristine (VCR), and dexamethasone (DEX) in adults with previously treated relapsed or refractory B-cell lineage acute lymphoblastic leukemia (ALL). This is a dose escalation study in which after 2 induction cycles participants may be put on maintenance for up to 36 cycles if they have obtained clinical benefit from the treatment.

- Monotherapy Lead-In (Day -7 to Day -1): Entospletinib (ENTO) 200 mg tablet orally twice daily as a single agent. Induction (two 28-day cycles): ENTO 200 mg twice daily continuously in combination with vincristine (VCR) 0.5 mg intravenously (IV) on Days 1, 8, 15, and 22 of each cycle; dexamethasone (DEX) 20 mg twice daily orally on Days 8-11 and Days 22-25 (Cycle 1) and on Days 1-4 and Days 15-18 (Cycle 2); and central nervous system (CNS) prophylaxis per institutional standards on Day 28 of each cycle. Maintenance (up to 36, 28-day cycles): Participants who achieved a complete remission (CR) received stem cell transplant (SCT) (if eligible) per investigator's discretion; others who obtained clinical benefit (ie, at least a partial response \[PR\]) after induction were offered maintenance therapy with ENTO 200 mg twice daily continuously in combination with VCR 0.5 mg on Day 1 of each cycle and DEX (20 mg daily or 10 mg twice daily) on Days 1-4 and Days 15-18 of each cycle.
