Clinical trials

This is a randomized, open-label, prospective, multicenter phase III superiority study in patients with newly diagnosed stage IV extranodal NK/T-cell lymphoma. The study compares two frontline induction strategies followed by consolidation with autologous hematopoietic stem cell transplantation in patients who achieve a protocol-defined strict complete remission. Eligible participants will be randomized 1:1 to Arm A or Arm B, stratified by three-level PINK-E risk category. Arm A consists of one cycle of GELAD induction followed by three cycles of MEDA chemotherapy. Participants who achieve strict complete remission after key response assessment will proceed to autologous hematopoietic stem cell transplantation consolidation. Arm B consists of four cycles of LEAP induction with sintilimab, pegaspargase, and anlotinib. Participants who achieve strict complete remission will receive high-dose methotrexate CNS-directed consolidation followed by autologous hematopoietic stem cell transplantation consolidation if eligible. The primary endpoint is event-free survival within 24 months after randomization. Secondary endpoints include progression-free survival, overall survival, overall response rate, complete remission rate, strict complete remission rate, autologous hematopoietic stem cell transplantation completion rate, cumulative incidence of relapse, grade 3 or higher adverse events, treatment discontinuation, treatment-related mortality, and plasma EBV-DNA clearance dynamics.

This is a prospective, multicenter, single-arm, open-label phase 2 study designed to evaluate the efficacy and safety of chidamide maintenance in adults with newly diagnosed double-expressor diffuse large B-cell lymphoma (DLBCL) who achieve complete response after induction therapy but remain ctDNA minimal residual disease (MRD)-positive. Eligible participants will receive oral chidamide 20 mg on Days 1, 4, 8, and 11 of each 21-day cycle. ctDNA MRD will be assessed every 12 weeks. Treatment will continue until two consecutive MRD-negative assessments, disease progression, intolerable toxicity, withdrawal of consent, or completion of 2 years of maintenance. The primary objectives are to evaluate ctDNA MRD negativity and 2-year progression-free survival. Secondary objectives include event-free survival, overall survival, and safety.

This is a multicenter, open-label, phase Ib/II study evaluating tislelizumab in combination with zeprumetostat (SHR2554) in patients with relapsed or refractory NK/T-cell lymphoma after at least one prior asparaginase-based chemotherapy-containing regimen, with or without radiotherapy. In phase Ib, two fixed dose levels of zeprumetostat in combination with tislelizumab will be evaluated to determine the recommended phase II dose (RP2D). In phase II, patients will be enrolled into 2 predefined cohorts according to prior exposure to PD-1 inhibitors to further evaluate efficacy and safety. The primary phase II endpoint is objective response rate at week 12 assessed by independent blinded imaging review according to Lugano 2014 criteria.

This study examines the safety, tolerability and preliminary efficacy of anti-CD19 /CD22 CAR T cells (KQ-2002)manufactured on-site in adults with relapsed or refractory CD19+ B cell acute lymphoblastic leukemia or CD19+ B cell non Hodgkin lymphoma.
