Viracor Eurofins offers first commercially available letermovir genotypic sequencing test to help healthcare professionals manage CMV

(LEE’S SUMMIT, MO – September 13, 2018) – Viracor Eurofins announced the addition of a new cytomegalovirus (CMV) gene sequencing assay for resistance to letermovir, the most recent FDA-approved CMV antiviral for use in adult Hematopoietic Stem Cell Transplant (HSCT) patients. While there has been no resistance identified in treatment-naive patients, clinical trials have shown resistance can develop in UL56 after exposure for some HSCT patients. Laboratory testing is recommended to quickly confirm the occurrence of resistance, as treatment modification based solely on clinical suspicion may result in added toxicity and increased time and complexity in patient management, if resistance is present in the patient.

CMV is a common virus that affects more than half of adults by the age of 40 years, according to the Centers for Disease Control and Prevention. While a healthy immune system is able to defend against CMV reactivation, CMV infections are a major cause of morbidity and mortality among immunocompromised and transplant patients. Viracor’s CMV drug resistance testing options equip healthcare providers with critical information when patients fail to respond to antivirals during prophylaxis or treatment.

The newest assay, CMV Resistance: Letermovir, became available in May 2018 as a standalone test, or as a complete panel with the other CMV drugs as CMV Resistance: Letermovir, Ganciclovir, Foscarnet, Cidofovir. Viracor also offers a CMV resistance test for UL54 and UL97, for ganciclovir, foscarnet and cidofovir.

These new assays add to Viracor’s menu of CMV testing options that help physicians across the continuum of care for immunocompromised patients with CMV. This includes PCR testing designed with dual gene targets to reduce false negative results, and a T Cell immunity Panel that was launched in 2017. Viracor’s CMV T Cell Immunity Panel uniquely evaluates CD4 and CD8 cells, with fast result turnaround time. Both CD4 and CD8 T cell responses are vital components of CMV immune control. Unlike many laboratories that are limited in the types of specimens they can process for testing, Viracor has validated and accepts 19 different specimen types for CMV Quantitative PCR testing, giving healthcare providers more options in complex or difficult cases.
