Letermovir Prophylaxis Duration Guided by CMV-Specific T-cell Monitoring After Allo-HSCT.
A Multicenter, Randomized, Controlled, Open-label Clinical Study to Evaluate the Efficacy and Safety of Letermovir Prophylaxis Duration Guided by Dynamic Monitoring of Specific T-cells for Preventing Cytomegalovirus Infection in Adult Recipients of Allogeneic Hematopoietic Stem Cell Transplantation in China.
The purpose of this study is to evaluate the efficacy and safety of a personalized strategy for discontinuing Letermovir (a drug used to prevent Cytomegalovirus [CMV] infection) based on the recovery of the patient's own immune system.
Cytomegalovirus (CMV) is a common and serious complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Currently, Letermovir is typically given as a standard prevention for about 100 days post-transplant. However, some patients may recover their CMV-specific immunity earlier, while others may need longer protection.
In this study, researchers will use a dynamic monitoring technology (QuantiFERON-CMV) to detect the level of CMV-specific T-cells in patients. Participants will be randomly assigned to either the experimental group or the control group:
Experimental Group: Letermovir discontinuation will be guided by T-cell recovery. If the test shows that the patient's CMV-specific T-cells have recovered, Letermovir may be stopped earlier than the standard 100 days.
Control Group: Patients will receive the standard Letermovir prophylaxis for approximately 100 days, regardless of T-cell status.
The study aims to determine if this immune-guided strategy can effectively prevent CMV infection while potentially reducing the duration of medication and associated costs, without increasing the risk of CMV disease.

The total number of days each participant received Letermovir prophylaxis from the start of treatment (between Day 0 and Day 28 post-HSCT) until the end of the intervention (up to 200 days).
This measure will compare the median duration of medication between the experimental arm (T-cell guided) and the control arm (standard 200-day prophylaxis) to evaluate the reduction in drug exposure.
