Lanoracopan to Prevent Acute GVHD Following Haploidentical Peripheral Blood Stem Cell Transplantation: A Prospective Multicenter Single-Arm Exploratory Study
Lanoracopan for Prevention of Acute Graft-Versus-Host Disease After Haploidentical Peripheral Blood Stem Cell Transplantation: A Prospective, Multicenter, Single-Arm Exploratory Study
This is a prospective, multicenter, open-label, single-arm exploratory study. Thirty adult patients with hematologic malignancies who are scheduled to receive haploidentical peripheral blood stem-cell transplantation with myeloablative conditioning will be enrolled.
All participants will receive standard anti-thymocyte globulin (ATG, total 7.5 mg/kg), standard graft-versus-host-disease (GVHD) prophylaxis (calcineurin inhibitor + mycophenolate mofetil + short-course methotrexate), plus lanoracopan 200 mg twice daily from day +1 to day +90 after stem-cell infusion. Lanoracopan is an approved complement alternative-pathway inhibitor being used off-label for GVHD prevention in this trial. Mandatory antibiotic prophylaxis against encapsulated bacterial pathogens will be given.
The primary goal is to evaluate the safety of lanoracopan in this transplant setting, including adverse events / serious adverse events, neutrophil and platelet engraftment, graft-failure rate, and infectious complications. The key secondary objective is to explore the cumulative incidence of grade II-IV acute GVHD at day 100 post-transplant. Additional secondary outcomes include chronic GVHD, TA-TMA, 1-year overall survival, disease-free survival, cumulative incidence of relapse, and non-relapse mortality. Exploratory biomarker assessments will be performed on plasma and serum samples.
Participants will be followed for 1 year after transplantation. No control group is included in this exploratory study.

実験的：Lanoracopan Combined With ATG and Standard GVHD Prophylaxis
|
200 mg oral, twice daily, administered from post-transplant day +1 to day +90. Off-label use for prevention of acute graft-versus-host-disease. Total dose 7.5 mg/kg, administered intravenously from pre-transplant day -5 to day -2. Standard-dose calcineurin inhibitor (either cyclosporine or tacrolimus) as part of routine GVHD prophylaxis. Mycophenolate mofetil given per local center routine for GVHD prophylaxis. Short-course methotrexate for standard GVHD prophylaxis after allogeneic stem-cell transplantation. |
