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.

Detailed description

Peripheral T-cell lymphomas (PTCL) are aggressive non-Hodgkin lymphomas with poor prognosis and high relapse rates after first-line chemotherapy. There is no established standard of care for post-remission maintenance therapy in patients who are not candidates for hematopoietic stem cell transplantation. Aberrant activation of the JAK/STAT pathway plays a critical role in the pathogenesis and progression of PTCL. Golidocitinib (Chinese name: 戈利昔替尼) is an oral, potent, and highly selective JAK1 inhibitor that has demonstrated robust antitumor activity and a favorable safety profile in relapsed or refractory PTCL in prior clinical studies, leading to its recommended phase II dose of 150 mg once daily. Based on these data and the unmet need for effective maintenance strategies, this phase III study (T-START-M1) will enroll adult patients with histologically confirmed PTCL subtypes (PTCL-NOS excluding primary cutaneous disease, ALK-ALCL, AITL, FTCL/PTCL-TFH) who achieved CR or PR after first-line CHOP, BV-CHP, or CHOP-like regimens and are ineligible for HSCT (age \>65 years) or decline HSCT despite eligibility. Randomization (1:1) will be stratified by initial response status (CR vs PR), histologic subtype (ALK-ALCL vs others), and HSCT eligibility (ineligible vs eligible-but-declining). Participants will receive golidocitinib 150 mg every other day or matching placebo in 28-day cycles for up to 24 months. Tumor response will be assessed by imaging according to Lugano 2014 criteria, and ctDNA-based MRD will be evaluated at baseline, 12 months, and end of treatment. Patients who achieve complete metabolic response plus MRD negativity at 12 months may stop maintenance, while others continue up to 2 years. After treatment discontinuation, patients will be followed for progression, subsequent anti-lymphoma therapies, and survival for up to approximately 13 additional cycles (about 1 year). The primary objective is to determine whether golidocitinib maintenance improves PFS compared with placebo. Key secondary objectives include evaluation of overall survival, complete response rate, duration of response, time to next anti-lymphoma therapy, ctDNA-based MRD dynamics, and safety including incidence of treatment-emergent adverse events (TEAEs), serious adverse events (SAEs), and grade ≥3 AEs.
