Brief summary
Graft-versus-host disease (GVHD) is an important complication after transplantation, with an incidence of 40-60%, which can increase non-relapse mortality if poorly controlled. At present, the standard prophylaxis for GVHD is cyclosporine combined with methotrexate. However, calcineurin inhibitors (CNI) can cause some vital side effects, which are not tolerated by some patients. Therefore, this study aims to explore the safety and efficacy of Sirolimus in combination with Ruxolitinib and Mycophenolate Mofetil for the prophylaxis of GVHD in patients with haplo-HSCT who are intolerant to calcineurin inhibitors.
Interventions
Sirolimus 2mg once daily, maintaining the concentration at 5-10 ng/ml. Gradually reduce the dosage after +100 days. If the patient has stable engraftment and no GVHD, discontinue on +180 days.
Ruxolitinib is administered at a dose of 5mg twice daily from the start of the study until +90 days. The dose is reduced to 5mg once daily on +90 days, and discontinued on +120 days.
MMF 0.5g, taken twice daily, is discontinued after 60 days. If it is resumed after 60 days, it should be taken for 2 weeks.
2.5 mg/kg, from -5d to -2d
