Brief Title: Study of ADCT-402 in Patients With Relapsed or Refractory B-cell Lineage Acute Lymphoblastic Leukemia (B-ALL)
Official Title: A Phase 1, Open-label, Adaptive Dose-escalation, Multicenter Study to Evaluate the Tolerability, Safety, Pharmacokinetics, and Anti-tumor Activity of ADCT-402 in Patients With Relapsed or Refractory B-cell Lineage Acute Lymphoblastic Leukemia (B-ALL)
Study ID: NCT02669264
Brief Summary: This study evaluates ADCT-402 in participants with relapsed or refractory B-cell lineage acute lymphoblastic leukemia (B-ALL). Participants will participate in a dose-escalation phase (Part 1) and dose expansion (Part 2). In Part 2, participants will receive the dose level identified in Part 1.
Detailed Description: Study ADCT-402-102 is the first clinical study with ADCT-402 in participants with B-cell lineage acute lymphoblastic leukemia (B-ALL). ADCT-402 is an antibody drug conjugate (ADC) composed of a humanized antibody directed against human cluster of differentiation 19 (CD19), stochastically conjugated via a valine-alanine cleavable, maleimide linker to a pyrrolobenzodiazepine (PBD) dimer cytotoxin. The study will be conducted in 2 parts. In Part 1 (dose escalation) participants will receive an infusion of ADCT-402 either on weekly administration or every 3-week administration. participants on weekly administration will receive an infusion of ADCT-402 on Days 1, 8, and 15 of each 3 week treatment cycle. Participants on 3-week administration will receive an infusion of ADCT-402 on Day 1, every 3 weeks. Dose escalation will continue until the maximum tolerated dose (MTD) is determined. In Part 2 (expansion), all participants will be assigned to the recommended dose and/or schedule of ADCT-402 identified in Part 1 by the Dose Escalation Steering Committee. For each patient, the study will include a screening period (up to 28 days), a treatment period (until withdrawal), and a follow-up period to assess disease progression and survival for up to 12 months after the last dose of study drug. The total study duration will be dependent on overall patient tolerability to the study drug and response to treatment. It is anticipated that the duration of the entire study (Parts 1 and 2) could be approximately 3 years from first patient treated to last patient completed.
