Transplant-Related Disorder
Conditions
Brief summary
This study aims to evaluate the efficacy of prophylactic ruxolitinib in adult patients at intermediate-to-high risk of severe acute GvHD, as predicted by the daGOAT model.
Interventions
1. Model-predicted high-risk patients: will receive standard prophylaxis plus ruxolitinib 5mg twice daily (bid) orally until at least day 60 post-transplantion and will be terminated after day 100. If severe hematological signs occur such as when there is severe neutropenia (\<0.1×10\^9/L), ruxolitinib can be used at half dose or discontinued until recovery. 2. Model-predicted moderate-risk patients: will receive standard prophylaxis plus ruxolitinib 5mg once daily (qd) orally until at least day 60 post-transplantion and will be terminated after day 100. If severe hematological signs occur such as when there is severe neutropenia (\<0.1×10\^9/L), ruxolitinib can be used at half dose or discontinued until recovery. 3. Model-predicted low-risk patients: will receive standard prophylaxis without additional GvHD prophylactic agents, including mesenchymal cell infusion, anti-CD25 monoclonal antibodies, and ruxolitinib outside the scope specified in the study protocol.

| aGVHD in various target organs according to the MAGIC criteria | 180 days after transplantation |
| Overall survival | 1.5 year after transplantation |
| Relapse-free survival rate | 1.5 year after transplantation |
| Relapse rate | 1.5 year after transplantation |
