Targeted agents plus CHOP compared with CHOP as the first-line treatment for newly diagnosed patients with peripheral T-cell lymphoma (GUIDANCE-03): an open-label, multicentre phase 2 clinical trial

Le résumé fourni par la source

Background: Peripheral T-cell lymphoma (PTCL) is a heterogeneous disease with dismal outcomes. We conducted an open-label, phase 2 nonrandomised, externally controlled study to evaluate the efficacy and safety of targeted agents plus CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone) (CHOPX) for PTCL in the front-line setting. Methods: , and lenalidomide if without mutations above. Patients in the CHOP group received CHOP for 6 cycles. The primary endpoint was the complete response rate (CRR) at the end of treatment (EOT). Secondary endpoints included overall response rate (ORR), progression-free survival (PFS), overall survival (OS), and safety. The study was registered with ClinicalTrials.gov, NCT04480099. Findings: = 0.088). The most common grade 3-4 hematological and non-hematological adverse events in the CHOPX group were neutropenia (31, 65%) and infection (5, 10%). Interpretation: Targeted agents combined with CHOP demonstrated effective and safe as first-line treatment in PTCL. Biomarker-driven therapeutic strategy is feasible and may lead to promising efficacy specifically toward molecular features in PTCL. Funding: This study was supported by the National Key Research and Development Program (2022YFC2502600) and the General Program of the Shanghai Municipal Health Commission (202040400).
