About this study
Official title: Post Authorization Study to Monitor Efficacy, Effectiveness, and Safety of Maribavir (LIVTENCITY®) in Patients With Post-transplant Cytomegalovirus (CMV) Infection in Argentina
The main aim of this study is to learn about the safety of Maribavir in adults and children with post-transplant CMV infection in routine clinical practice in Argentina.
The other aim is to study the effectiveness of the treatment with Maribavir in routine clinical practice in Argentina.
Participants will be treated by their doctors according to normal medical practice. Study data will be collected either from information already available in the medical records or during study conduct.
- Conditions

| Study group | Role | What they receive |
|---|---|---|
| All Participants | Participants who have received maribavir treatment for the approved indication after marketing authorization (de novo participants) and before marketing authorization (legacy participants) under expanded access type of program or compassionate use in the real-world setting. Data will be collected prospectively and/or retrospectively from the medical records during this observational period of 16 weeks. Receives: Other: No Intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Participants With Adverse Events (AEs)
An AE is any untoward medical occurrence in a clinical investigation participant administered a medicinal product and which does not necessarily have a causal relationship with this treatment. AEs will include both serious and non-serious AEs.
Measured: From start of treatment up to Week 16
Secondary outcomes (3)
Percentage of Participants Who Achieved Clearance of Plasma Cytomegalovirus -Deoxyribonucleic Acid (CMV-DNA) (CMV Viremia Clearance) at End of Weeks 8 and 16
CMV viremia clearance will be defined as CMV DNA concentration below the lower limit of considered by each local site for clearance according to real-world clinical practice.
Measured: At Weeks 8 and 16
Percentage of Participants Who Achieved CMV Infection Symptom Control at End of Weeks 8 and 16
CMV infection symptom control will be defined as resolution or improvement CMV disease/syndrome for participants symptomatic at baseline, or absence of the development of CMV disease/syndrome or participants asymptomatic at baseline.
Measured: At Weeks 8 and 16
Percentage of Participants Who Achieved a Clinically Relevant Response Regardless of Whether Treatment was Discontinued Before 8 weeks of Therapy
Clinically relevant response will be defined as no need for the use of an antiviral at a therapeutic dose for at least 4 weeks after completing treatment with maribavir, due to clinical improvement (improvement of CMV-related symptoms or the absence of these in the case of asymptomatic infections) and virological improvement (decrease of at least 1 log of viremia during treatment with maribavir).
Measured: Up to Week 8
