Merck Announces FDA Acceptance of New Drug Application for an Investigational Tablet Formulation of the Antifungal …

WHITEHOUSE STATION N.J.--(BUSINESS WIRE)--

Merck (MRK), known as MSD outside the United States and Canada, today announced that its New Drug Application for an investigational, tablet formulation of the company's antifungal agent, NOXAFIL (posaconazole), has been accepted for review by the U.S. Food and Drug Administration (FDA).

Merck currently markets NOXAFIL Oral Suspension for prophylaxis of invasive Aspergillus and Candida infections in patients 13 years of age and older who are at high risk of developing these infections due to being severely immunocompromised, such as patients who have received hematopoietic stem cell transplants and have graft-versus-host disease, or patients with cancers of the blood who are experiencing prolonged low white blood cell counts (neutropenia) as a result of chemotherapy.

Invasive fungal infections are a significant cause of illness and death among severely immunocompromised patients, said Robin Isaacs, M.D., vice president, infectious disease clinical research, Merck Research Laboratories. This filing for a tablet formulation of NOXAFIL is an example of Mercks ongoing commitment to developing new therapy options for patients in the hospital setting.

Merck is seeking FDA approval of NOXAFIL tablets for once-daily administration (following a twice-a-day loading dose on the first day of therapy). The company has filed a marketing authorization application for NOXAFIL tablets with the European Medicines Agency (EMA) and plans to seek regulatory approval for the tablet formulation in other countries around the world.

Selected safety information about NOXAFIL (posaconazole) Oral Suspension

NOXAFIL is contraindicated in persons with known hypersensitivity to posaconazole, any component of NOXAFIL, or other azole antifungal agents.

NOXAFIL is contraindicated with sirolimus. Concomitant administration of NOXAFIL with sirolimus increases the sirolimus blood concentrations by approximately 9-fold and can result in sirolimus toxicity.

NOXAFIL is contraindicated with the CYP3A4 substrates that prolong the QT interval. Concomitant administration of NOXAFIL with the CYP3A4 substrates pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and rare occurrences of torsades de pointes.

NOXAFIL is contraindicated with HMG-CoA reductase inhibitors that are primarily metabolized through CYP3A4 (e.g., atorvastatin, lovastatin, and simvastatin) as increased plasma concentration of these drugs can lead to rhabdomyolysis.
