Secondary Prophylaxis of CMV Infection Using Letermovir After HID-HSCT
Study Details
Study Description
Brief Summary
To evaluate the efficacy and safety of secondary prophylaxis of CMV reactivation, clinically significant CMV infection with oral letermovir in Chinese haplo-HSCT patients, as well as treatment-related mortality, all-cause mortality and QoL after transplantation. For enrolled patients, Letermovir would be administered at a dose of 480 mg per day (or 240 mg per day in patients taking cyclosporine). The regimen duration of dosing was approximately 120 days or 16 weeks. Or physicians could adjust regimen duration according to the CMV infection risk factors.

Outcome Measures
Primary Outcome Measures
- Incidence of CMV reactivation and CMV infection [1 year after letermovir administration]
The incidence of peripheral blood cytomegalovirus activation and confirmed clinically significant CMV infection occurred within 1 year after treatment; if the patient terminated letemovir treatment for any reason after treatment, or clinical data loss occurred within 1 year, it was also included in the primary endpoint event.
Eligibility Criteria
Criteria
Inclusion Criteria:
- (1) Underwent HLA-haploidentical donor HSCT, after at least 1 treated CMV episode since transplant in patients who did not receive primary prophylaxis.

(4) HIV negative, HBV, HCV negative; (5) Informed consent must be signed before the start of the study procedures, and informed consent must be signed by the patient himself or his immediate family. Considering the patient 's condition, if the patient' s signature is unfavorable for disease treatment, the informed consent form should be signed by the legal guardian or the patient 's immediate family member

(7) has both moderate hepatic insufficiency AND moderate renal insufficiency; (8) Uncontrolled infection at enrollment; (9) requires mechanical ventilation or is hemodynamically unstable at the time of enrollment; (10) has documented positive results for human immunodeficiency virus antibody (HIVAb), hepatitis C virus antibody (HCV-Ab) with detectable HCV RNA, or hepatitis B surface antigen (HBsAg) within 90 days prior to enrollments; (11) has active solid tumor malignancies with the exception of localized basal cell or squamous cell skin cancer or the condition under treatment (e.g., lymphomas).
(12) Suffering from mental disorders or other conditions and unable to cooperate with the requirements of study treatment and monitoring; (13) unable or unwilling to sign the consent form; (14) pregnant or lactating women; (15) patients with other special conditions assessed as unqualified by the investigator
