Genotype-guided Treatment in Newly Diagnosed PTCL

Официальное название

Guidance-04：T-cell Lymphoma Series：A Genotype-guided Therapy in Newly Diagnosed Patients With Peripheral T-cell Lymphoma （THEORY Study）

Обзор

This study includes Phase I and Phase II stages. Phase I is an open-label trial to confirm RP2D of oral targeted agents in three genetic subtypes. Phase II is a multicenter, prospective, randomized, open-label, controlled trial to evaluate the efficacy and safety of 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 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 oral targeted agents will be confirmed by traditional "3+3" dose escalation methods. In phase II, patients will receive standard CHOP for the first cycle and then 1:1 be randomized to CHOPX2 or CHOP regimen in each genetic subtypes.
