Letermovir is already approved in many countries, including Australia, for preventing cytomegalovirus (CMV) infections in patients who have received stem cell transplants. However, its pharmacokinetics - or how the drug is absorbed, distributed, and cleared from the body - have not been studied in patients with ESKD, especially those on dialysis.\n\nThis is a single-centre, open-label, interventional pharmacokinetic study. It will recruit 20 adult participants, split into two groups: 10 participants on intermittent haemodialysis and 10 not undergoing dialysis. All participants will receive a single oral dose of 480 mg letermovir. The study does not involve treatment for CMV infection. Instead, it focuses only on how the drug behaves in the body in this patient population.\n\nParticipants will have blood samples collected before and after taking the medication to measure drug concentrations over time. In patients on dialysis, an additional sample will be taken from the dialysis machine to understand if letermovir is removed during treatment. No more than 35 mL of blood (around two tablespoons) will be collected across two study visits.\n\nThe goal of this study is to generate important safety and dosing information to help guide future use of letermovir in people with kidney failure. It is expected that these findings will support more informed clinical decisions and potentially lead to updated dosing recommendations for this group.\n\nThe study is funded by Merck Sharp \\& Dohme LLC (MSD), the manufacturer of letermovir, and is being conducted by researchers from The University of Queensland Centre for Clinical Research (UQCCR) and the Royal Brisbane and Women's Hospital (RBWH). To support participation, prepaid meal vouchers, taxi vouchers, or parking tickets will be provided so that participants do not incur any out-of-pocket expenses.\n\nParticipation is voluntary. The study has been approved by a Human Research Ethics Committee and is conducted according to national ethical guidelines.",[64],"End-Stage Kidney Disease (ESKD)",[66,67,68,69,70],"pharmacokinetics","letermovir","intermittent haemodialysis","renal impairment","chronic kidney failure","NOT_YET_RECRUITING","2025-07-30",{"date":74,"type":75},"2025-08-03","ACTUAL",{"date":77,"type":58},"2025-09",{"date":79,"type":58},"2027-12",{"name":37,"class":6}]
