PHASE1/PHASE2

Linperlisib Combined With Chidamide in Patients With PTCL

Sponsor: Yanyan Liu

View on ClinicalTrials.gov

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.

DRUG

Linperlisib and chidamide

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.

DRUG

Linperlisib and chidamide

All patients received Linperlisib at the RP2D dose once daily and Chidamide 20 mg twice weekly, with each treatment cycle lasting 3 weeks. After three cycles, an interim efficacy assessment was performed. Patients who showed a therapeutic response received an additional three cycles, and the final efficacy evaluation was conducted after six cycles.

DRUG

Linperlisib and chidamide

Patients received Linperlisib at the RP2D dose once daily and Chidamide 20 mg twice weekly, with each treatment cycle lasting 3 weeks. After three cycles, an interim efficacy assessment was performed. Patients who showed a therapeutic response received an additional three cycles, and the final efficacy evaluation was conducted after six cycles.

DRUG

cyclophosphamide, doxorubicin/epirubicin, vincristine, and prednisone

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.

Inclusion Criteria: * Age 18-75 years at the time of inclusion (Age 18-80 years for phase Ib and IIa study) * Patients with a newly diagnosed and histologically confirmed PTCL (phase Ib study includes both newly diagnosed and relapsed/refractory PTCL).
