Golidocitinib Versus Placebo as Maintenance Therapy for Peripheral T-Cell Lymphoma

Brief Summary

This is a multicenter, randomized, double-blind, placebo-controlled phase III trial evaluating golidocitinib as maintenance therapy in adult patients with peripheral T-cell lymphoma (PTCL) who achieved complete response (CR) or partial response (PR) after first-line systemic chemotherapy and are not candidates for hematopoietic stem cell transplantation (HSCT) or decline HSCT. Eligible patients with histologically confirmed PTCL subtypes (PTCL-NOS, ALK-positive anaplastic large cell lymphoma \[ALK-ALCL\], angioimmunoblastic T-cell lymphoma \[AITL\], or follicular helper T-cell phenotype PTCL \[FTCL/PTCL-TFH\]) according to the 2016 WHO classification will be randomized 1:1 to receive oral golidocitinib or matching placebo. Study treatment is given at 150 mg every other day in 28-day cycles for up to 2 years or until disease progression, unacceptable toxicity, start of new anti-lymphoma therapy, withdrawal of consent, or study termination. At 12 months, patients who achieve complete metabolic response on PET-CT and minimal residual disease (MRD)-negative status by ctDNA may discontinue maintenance, whereas others continue treatment up to 24 months. After treatment discontinuation, patients will be followed for disease status and survival for up to approximately 13 additional cycles. The primary endpoint is progression-free survival (PFS) assessed by investigators per Lugano 2014 criteria. Key secondary endpoints include overall survival, response rates, duration of response, time to next anti-lymphoma therapy, MRD dynamics by ctDNA, and safety.
