Brief summary
This is a prospective, single-center phase I/II study, with the purpose of evaluating the efficiency of golidocitinib combined with chidamide in patients with systemically-treated cutaneous T-cell lymphoma. The primary endpoint of the phase I study was to determine the recommended phase II dose (RP2D), while the primary endpoint of the phase II study was the objective response rate (ORR). Secondary endpoints included the complete response (CR) rate, progression-free survival (PFS), duration of response (DOR), overall survival (OS), and safety profile.
Detailed description
of golidocitinib in combination with chidamide and to determine the recommended phase II dose (RP2D). The study follows a standard "3+3" design. The starting dose of golidocitinib is 150 mg every other day, with pre-specified dose levels including 150 mg every other day and 150 mg once daily. Chidamide is administered at a fixed dose of 20 mg twice weekly. In the phase II segment (dose expansion phase), all participants will receive the combination therapy of golidocitinib and chidamide. Golidocitinib will be administered at the RP2D established in the phase I study, while chidamide will continue at the fixed dose of 20 mg twice weekly. Each treatment cycle is defined as 4 weeks. Tumor response will be assessed every 3 treatment cycles, and safety evaluations will be performed every cycle.

Exclusion criteria
* Acute myocardial infarction, unstable angina, congestive heart failure, symptomatic arrhythmia within the past 6 months, or significant QT interval prolongation (corrected QT interval \>450 ms in males or \>470 ms in females). * Uncontrolled active infection. * Active tuberculosis infection. * Active Hepatitis B (HBV DNA \> 1×10³ copies/mL) or Hepatitis C (HCV RNA \> 1×10³ copies/mL) infection. * Pregnancy or lactation. * Any other condition deemed by the investigator as unsuitable for participation in this study.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Recommended Phase II Dose (RP2D) | From enrollment to the end of treatment at 4 weeks | The RP2D is determined based on the occurrence of dose-limiting toxicities (DLTs) during the first cycle (28 days) of treatment. It is defined as the highest dose level at which fewer than 33% of participants experience a DLT. |
| Objective Response Rate (ORR) | From enrollment to the end of 2-year follow-up phase or disease progression or death due to any cause | ORR is defined as the proportion of participants achieving a best overall response of complete response (CR) or partial response (PR). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Complete Response (CR) Rate | From enrollment to the end of 2-year follow-up phase or disease progression or death due to any cause | Proportion of participants achieving a complete response (CR) |
| Progression-Free Survival (PFS) | From enrollment to the end of 2-year follow-up phase or disease progression or death due to any cause | the time from the first dose of study drug to the first documented disease progression or death |
| Overall Survival (OS) | From enrollment to the end of 2-year follow-up phase or death from any cause | the time from the first dose of study drug to death from any cause |
