Brief Summary
The phase Ib part of this study aims to determine the recommended phase II dose (RP2D)of linperlisib in combination with chidamide for the treatment of peripheral T-cell lymphoma (PTCL). The phase IIa part is designed to evaluate the preliminary efficacy and safety of the linperlisib plus chidamide regimen in newly diagnosed PTCL patients. The phase IIb part compares the efficacy and safety of linperlisib combined with chidamide versus the standard CHOP (CHOP-like) regimen in newly diagnosed PTCL patients.

Study Arms (4)
Phase Ib: Dose-escalation cohort
EXPERIMENTALLinperlisib was administered in three dose groups of 40 mg, 60 mg, and 80 mg once daily (QD), with each group enrolling 3-6 patients with newly diagnosed or relapsed/refractory PTCL. Chidamide was given at a fixed dose of 20 mg twice weekly. During the 21-day DLT (dose-limiting toxicity) observation period, the maximum tolerated dose (MTD) of linperlisib was assessed, and the recommended phase II dose (RP2D) was determined for use in the phase II study.
Phase IIa: Expansion cohort
EXPERIMENTALIn newly diagnosed PTCL patients, the efficacy and safety of Linperlisib (RP2D) combined with Chidamide were evaluated. Each treatment cycle is 3 weeks, and patients who responded effectively would receive a total of six cycles of therapy.
Phase IIb: Randomized controlled study: experimental arm
EXPERIMENTALPatients randomized to the experimental group will receive combination therapy with Linperlisib and Chidamide.
Phase IIb: Randomized controlled study: Control arm
ACTIVE COMPARATORPatients randomized to the control group will receive conventional CHOP or CHOP-like regimen chemotherapy.
Interventions
Linperlisib is a selective PI3Kδ inhibitor that has been approved in mainland China for the treatment of relapsed or refractory follicular lymphoma, with a recommended monotherapy dose of 80 mg orally once daily. In this study, Linperlisib was administered at three dose levels of 40 mg, 60 mg, and 80 mg in order to determine the recommended Phase II dose (RP2D) when combined with a fixed dose of Chidamide (20 mg twice weekly). Chidamide has been approved in mainland China for the treatment of relapsed or refractory PTCL and double-expressor DLBCL. In this study, it was administered at a fixed dose of 20 mg twice weekly in combination with Linperlisib.
Patients receive conventional CHOP (or CHOP-like regimens such as CHOPE or EPOCH) chemotherapy, with 3 weeks for one cycle. After three cycles, an interim efficacy assessment was performed. Patients who showed a response received an additional three cycles, and the final efficacy evaluation was conducted after six cycles.
Eligibility Criteria
You may qualify if:
- Patients with a newly diagnosed and histologically confirmed PTCL (phase Ib study includes both newly diagnosed and relapsed/refractory PTCL). Anaplastic large cell lymphoma, NK/T-cell lymphoma, and primary cutaneous T-cell lymphoma are not included.
- ECOG PS 0-2 at protocol entry
- Estimated life expectancy of 6 months or longer
- Measurable disease
- Hemoglobin ≥ 8 g/dL (≥5 mmol/l); Platelets ≥ 75 x 10E9/L; Absolute neutrophil count ≥ 1.0 x 10E9/L; Platelets ≥ 50 x 10E9/L permitted if documented bone marrow involvement; Serum bilirubin ≤ 1.5 x upper limit of normal (ULN); Serum glutamic-oxaloacetic transaminase (AST) and/or serum glutamic-pyruvic transaminase (ALT) ≤ 2.5 x ULN, or ≤ 5 x ULN if elevation is due to hepatic involvement by lymphoma; Serum creatinine ≤ 1.5 x ULNb; left ventricular ejection fraction (LVEF) ≥ 50%
- Women of childbearing potential must use safe anticonception (e.g. contraceptive pills, intrauterine devices etc.) during the study and 12 months after the last administration of study drugs; Male patients must use contraception for the duration of the study and 6 months after the last administration of study drugs if his partner is of childbearing potential
- Written informed consent
You may not qualify if:
- Patients previously treated with PI3K inhibitor
