A Phase I/II Study of ASTX660 in Patients With Relapsed or Refractory T-cell Lymphoma
A Phase I/II, Multicenter, Open-Label, Nonrandomized Study to Evaluate the Tolerability and Safety of ASTX660 and the Efficacy at the Recommended Dose of ASTX660 in Patients With Relapsed or Refractory T-Cell Lymphoma
Phase 1 (dose-escalation part): Investigate the tolerability and safety of ASTX660 in patients with r/r PTCL and r/r CTCL and determine the recommended dose (RD) for the Phase 2.
Phase 1 (ATLL expansion part): Evaluate the safety of ASTX660 at RD in patients with r/r ATLL.
Phase 2 : Evaluate the efficacy of ASTX660 at RD in patients with r/r PTCL.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Phase 1 dose-escalation part
Subjects with r/r PTCL and r/r CTCL will receive ASTX660 once a day for 7 consecutive days every other week of each 28-day cycle (ie, [7 days on/ 7 days off] ×2; daily dosing on Days 1-7 and 15-21).
The starting dose will be escalated stepwise in successive cohorts of 3 to 6 evaluable subjects each (standard 3+3 study design), until the RD is determined.
