Study Overview
Brief Summary
This is a single-center, prospective, randomized, dose-escalation Phase II clinical study. A total of 46 patients with newly diagnosed depression following allogeneic hematopoietic stem cell transplantation (allo-HSCT) will be enrolled.
Participants will be randomly assigned to receive different doses of Xiaochaihu Granules in addition to standard post-transplant care for 100 days. The primary objective is to evaluate the efficacy of Xiaochaihu Granules in improving depressive symptoms. Secondary objectives include assessment of safety and clinical outcomes such as event-free survival (EFS), graft-versus-host disease (GVHD), infections, and other transplantation-related complications.
Detailed Description
This is a single-center, prospective, randomized, dose-escalation Phase II clinical trial designed to evaluate the efficacy and safety of Xiaochaihu Granules in patients with depression following allogeneic hematopoietic stem cell transplantation (allo-HSCT).
A total of 46 eligible patients with newly diagnosed depression after allo-HSCT will be enrolled. Participants will be randomly assigned to receive either a low-dose or high-dose regimen of Xiaochaihu Granules, administered orally twice daily for 100 days, in addition to standard post-transplant care.
The primary endpoints include changes in depression severity as assessed by validated scales (e.g., HADS and HAMD) and changes in symptom burden. Secondary endpoints include event-free survival (EFS), incidence of graft-versus-host disease (GVHD), infections, viral reactivation, engraftment outcomes, and overall safety.
