Maribavir was approved by the US Food and Drug Administration for treatment of patients aged ≥12 years weighing ≥35 kg with posttransplant cytomegalovirus infection/disease refractory (with/without resistance) to valganciclovir, ganciclovir, cidofovir, or foscarnet, an oral dose 400 mg twice daily. With no pediatric clinical data available difficulty in trial recruitment, population pharmacokinetic modeling simulations were conducted predict pharmacokinetics inform maribavir dosing adolescents.

Abstract The effect of food composition, tablet crushing, and antacid coadministration on maribavir pharmacokinetics was assessed in 2 Phase 1 studies healthy adults. In the first, a single 400‐mg dose administered under fasting conditions, with low‐fat/low‐calorie or high‐fat/high‐calorie meal. second, 100‐mg as crushed tablet, whole alone an antacid. 90% confidence intervals geometric mean ratios were within 80%‐125% for area concentration‐time curve (AUC), but not maximum plasma...

Abstract Maribavir, an orally available antiviral agent, has been approved in multiple countries for the treatment of patients with refractory post‐transplant cytomegalovirus (CMV) infection and/or disease. Maribavir is primarily metabolized by CYP3A4; coadministration CYP3A4 inducers and inhibitors may significantly alter maribavir exposure, thereby affecting its efficacy safety. The effect on exposure was evaluated based a drug‐drug interaction (DDI) study physiologically‐based...

Introduction Maribavir, a potent and orally bioavailable antiviral, is being evaluated in Phase 3 trials for the treatment of cytomegalovirus (CMV) infections transplant patients. Often numerous concomitant medications are administered to these patients manage their comorbidities. A thorough evaluation maribavir potential drug–drug interactions (DDIs) warranted required regulatory approval. Objectives To thoroughly evaluate DDIs maribavir. Methods Extensive vitro studies were conducted...

This study was designed to increase the throughput of rat brain microdialysis studies by administration compounds as a cassette opposed discrete study. Eight (carbamazepine, citalopram, desmethylclozapine, diphenhydramine, gabapentin, metoclopramide, naltrexone, and stavudine) were selected administered an intravenous bolus dose at 0.5–3.3 mg/kg each followed infusion 1 per hour for 6 hours in rats or dosing. The dialysate, plasma, brain, cerebrospinal fluid collected analyzed using liquid...

Maribavir is in phase 3 clinical development for treatment of cytomegalovirus infection/disease transplant recipients. Previous research conducted using only intact cynomolgus monkeys indicated biliary secretion as the primary elimination pathway maribavir and that undergoes enterohepatic recirculation (EHR). To clarify exact mechanisms maribavir's EHR behavior, we studied its clearance pathways intravenously administered 14C-labeled bile duct-cannulated (BDC) constructed a...

Ovarian cancer is one of the three most malignant tumors female reproductive system. At present, researchers do not know its pathogenesis, which makes treatment effect unsatisfactory. Metabolomics closely related to drug efficacy, safety evaluation, mechanism action, and rational use. Therefore, identifying ovarian cancer-related metabolites could greatly help understand pathogenesis develop plans. However, measurement inaccurate affects environment, biological experiment time-consuming...

The prodrug strategy has been frequently employed as a chemical approach for overcoming the disadvantages of existing parent drugs. In this report, we synthesized four monoester prodrugs ganciclovir, an anticytomegalovirus drug, and demonstrated their potential advantages in protease-targeted activation biopharmaceutical profiles over compound. We that these i.e., N-benzyloxycarbonyl-(L)-alanine-ganciclovir (CbzAlaGCV), N-benzyloxycarbonyl-(α,l)-aminobutyric acid-ganciclovir (CbzAbuGCV),...
