Clinical Trials Using Letermovir
Clinical trials are research studies that involve people. The clinical trials on this list are studying Letermovir. All trials on the list are supported by NCI.
NCI’s basic information about clinical trials explains the types and phases of trials and how they are carried out. Clinical trials look at new ways to prevent, detect, or treat disease. You may want to think about taking part in a clinical trial. Talk to your doctor for help in deciding if one is right for you.
Extension of Letermovir (LET) From Day 100 to Day 200 Post-transplant for the Prevention of Cytomegalovirus (CMV) Infection in Hematopoietic Stem Cell Transplant (HSCT) Participants (MK-8228-040)
The purpose of this study is to evaluate the safety and efficacy of letermovir (LET) versus placebo when extended from 100 days to 200 days post-transplant in cytomegalovirus (CMV) seropositive participants who received an allogenic hematopoietic stem cell transplant (HSCT). It is hypothesized that LET is superior to placebo in the prevention of clinically-significant CMV infection when LET prophylaxis is extended from 100 to 200 days.

Letermovir in Treating Patients with Resistant Cytomegalovirus Infection or Disease with Organ Dysfunction
This trial studies how well letermovir works in treating patients with active cytomegalovirus (CMV) infection who are undergoing transplant. Letermovir is a drug that acts against infections caused by CMV and may help treat active CMV infection or disease with organ dysfunction.

Triplex Vaccine in Preventing CMV Infection in Patients Undergoing Hematopoietic Stem Cell Transplantation
This phase II trial studies how well Triplex vaccine works in preventing cytomegalovirus (CMV) infection in patients undergoing a hematopoietic stem cell transplantation. CMV is a virus that may be carried for life and does not cause illness in most healthy individuals. However, in people whose immune systems are lowered (such as those undergoing stem cell transplantation), CMV can reproduce and cause disease and even death. The Triplex vaccine is made up of 3 small pieces of CMV deoxyribonucleic acid (DNA) (the chemical form of genes) placed into a weakened virus called modified vaccinia Ankara (MVA) that may help produce immunity (the ability to recognize and respond to an infection) and reduce the risk of developing complications related to CMV infection.

Letermovir Treatment in Pediatric Participants Following Allogeneic Haematopoietic Stem Cell Transplantation (HSCT) (MK-8228-030)
The primary objective of this study is to evaluate the pharmacokinetics (PK) of letermovir (LET) in pediatric participants. Participants will be enrolled in the following 3 age groups: Age Group 1: From 12 to <18 years of age (adolescents); Age Group 2: From 2 to <12 years of age (children); and Age Group 3: From birth to <2 years of age (neonates, infants and toddlers). All participants will receive open label LET for 14 weeks (~100 days) post-transplant, with doses based on body weight and age.

A Study of the Drug Letermovir as Prevention for Recurrence of Cytomegalovirus Infection
This phase II trial studies how well letermovir works in preventing cytomegalovirus infection from coming back (recurring) in high-risk stem cell transplant patients. Letermovir is an antiviral drug that stops cytomegalovirus from multiplying and may prevent cytomegalovirus infection and make the disease less severe.
