Maribavir: First Approval.

Maribavir (LIVTENCITYTM), a cytomegalovirus (CMV) enzyme pUL97 kinase inhibitor, is being developed by Takeda Pharmaceuticals for the treatment of CMV infections. Maribavir was recently approved in the USA for the treatment of post-transplant CMV infection/disease that is refractory to treatment (with or without genotypic resistance) with ganciclovir, valganciclovir, cidofovir or foscarnet in adults and paediatric (≥ 12 years of age and weighing ≥ 35 kg) patients. This article summarizes the milestones in the development of maribavir leading to this first approval for CMV infections.
