Letermovir Prophylaxis for Cytomegalovirus Infection in Haploidentical Allogeneic Hematopoietic Cell Transplant Recipients: Single-center Real-world Data in China
In Brief
An observational study evaluating Letermovir for CMV Infection and Hematopoietic Stem Cell Transplantation. Completed, enrolled 200 participants across 1 site.
Detailed Summary
In the 30 years of fighting CMV infection, the mortality rate among HSCT patients has significantly reduced. Now, the focus is on improving the prognosis of HSCT patients and preventing CMV infection. The emergence of letermovir has provided a new opportunity in this regard. Letermovir, the only drug approved for CMV infection prevention in HSCT patients, works by inhibiting the CMV DNA terminase complex. Phase III studies have shown that letermovir significantly reduces CMV infection and all-cause mortality after HSCT, without increasing myelosuppression or nephrotoxicity. Real-world studies have further confirmed its efficacy in reducing CMV infection rates and antiviral use. Letermovir's global success has not yet been fully realized in China, where it is still in its early stages of use.
Study Details
Timeline
Interventions
Letermovir has achieved excellent therapeutic benefits globally but is still in its infancy in China. Letermovir obtained an implied license for a clinical trial in June 2020, and in November 2020, Letermovir submitted and accepted four new drug marketing applications in China, including injection and tablet formulations. On December 31, 2021, the China National Medical Products Administration (NMPA) approved letermovir for cytomegalovirus (CMV) seropositive adult recipients undergoing allogeneic hematopoietic stem cell transplantation (HSCT) \[R+\] prevention of cytomegalovirus infection and cytomegalovirus disease. The commercial launch of letermovir is estimated to be in August 2022.
