Viracor Eurofins CMV Resistance:Letermovir

Viracor Eurofins has launched CMV Resistance:Letermovir, a cytomegalovirus gene sequencing assay for the detection of resistance to Prevymis (letermovir), an antiviral for use in adult hematopoietic stem cell transplant patients. The assay is available as a standalone test or as a complete panel with the other CMV drugs as CMV Resistance: Letermovir, Ganciclovir, Foscarnet, Cidofovir. Viracor Eurofins said that resistance to Prevymis has not been detected in treatment-naive patients, but noted that clinical trials have shown that resistance can develop in the UL56 gene after exposure for some HSCT patients.
