Trial Arms
Name | Type | Description | Interventions |

Phase 1 dose-escalation part | Experimental | 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. | |
Phase 1 ATLL expansion part | Experimental | Subjects with r/r ATLL will receive ASTX660 at RD obtained from the Phase 1 part (dose-escalation part) once a day for 7 consecutive days every other week of each 28-day cycle. | |
Phase 2 | Experimental | Subjects with r/r PTCL will receive ASTX660 at RD obtained from the Phase 1 part (dose-escalation part) once a day for 7 consecutive days every other week of each 28-day cycle. | |
