Peripheral T Cell Lymphoma
Conditions
Brief summary
HDAC inhibitor chidamide and PI3K inhibitor linperlisib has shown clinical activity as mono-therapy in PTCL. The combination of duvelisib and romidepsin is highly active for relapsed and refractory PTCLs. The aim of this study is to further explore the efficacy and safety of HDAC inhibitor chidamide combined with PI3K inhibitor linperlisib in the treatment of relapsed and refractory PTCLs.
Interventions
* Phase 1: dose escalation phase. Drug Linperlisib: 3 dose level of 40mg, 60mg, 80mg qd; Drug Chidamide: fixed dose of 20mg twice weekly in a 4-week cycle; * Phase 2: dose expansion phase. Drug Linperlisib: RP2D established in the phase I study; Drug Chidamide: fixed dose of 20mg twice weekly in a 4-week cycle;

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recommended phase 2 dose (RP2D) | 4 weeks since the date of first dose | Recommended phase 2 dose (RP2D) and/or maximum tolerated dose (MTD) will be established according to the incidence of dose-limiting toxicities (DLTs) of escalated doses of linperlisib. |
| Objective response rate (ORR) | evaluated every 3 months (up to 24 months) | Objective response rate (ORR) for phase 2 study |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival | recruitment to data cut-off (up to 5 years) | Progression-free survival was defined as the time from the date of enrollment until the date of the first documented day of disease progression or relapse, or death from any cause, whichever occurred first. |
| Overall survival | recruitment to data cut-off (up to 5 years) | Overall survival was defined as the time from the date of enrollment to the date of death from any cause. |
| complete remission (CR) rate | evaluated every 3 months (up to 24 months) | Treatment responses were assessed according to the 2014 Lugano classification criteria |
| adverse events | evaluated every treatment cycle (up to 24 months) | Graded according to the Common Terminology Criteria for Adverse Events (CTCAE) version 5.0 |
