New Genotype-guided Treatment in Newly Diagnosed PTCL

Официальное название

A New Genotype-guided Therapy in Newly Diagnosed Patients With Peripheral T-cell Lymphoma

Обзор

This is a phase I/II study evaluate the safety and efficacy targeted agents in combination with standard CHOP in new genotypic subtypes in treatment naive peripheral T-cell lymphoma. Phase I is to confirm RP2D of targeted agent. Phase II is a multicenter, prospective, randomized, open-label, controlled design to evaluate the efficacy and safety of new genotype-guided targeted agents plus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP-X2) versus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with peripheral T-cell lymphoma.

Подробное описание

Peripheral T-cell lymphoma (PTCL) is a heterogeneous disease with dismal outcomes. Standard CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) chemotherapy is still the most widely used front-line treatment of PTCL except Brentuximab-CHP application in anaplastic large cell lymphoma (ALCL). The CR rate ranges from 31%-56% in different studies with different PTCL histology compositions. With the exception for ALCL-anaplastic lymphoma kinase (ALK)-positive, the 5-year overall survival (OS) rate is approximately 30%-40% for most subtypes of PTCL patients in current situation, remaining as the unmet medical needs in this disease. Based on genetic subtypes in PTCL, and our previous study exploring targeted agents plus CHOP based on genetic mutations (Guidance-03 and Guidance-04 study), we conducted this multicenter, prospective, randomized, open-label, controlled trial to evaluate the efficacy and safety of genotype-guided targeted agents plus CHOP (CHOP-X2) versus cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) in patients with PTCL. It includes phase I and phase II stages. Patients will receceived stardard CHOP for the first cycle and then obtain the genetic subtypes from tumor NGS befor Cycle 2. In phase I, recommended phase 2 dose (RP2D) of targeted agents will be confirmed. In phase II, patients will receive standard CHOP for the first cycle and then 1:1 be randomized to CHOPX2 or CHOP regimen in four genetic subtypes.
