Otesaconazole (previously known as VT-1161), an antifungal agent, is an oral inhibitor of fungal lanosterol demethylase (CYP51) but did not inhibit human CYP51. Inhibition of CYP51 results in the accumulation of chemicals known to be toxic to the fungus. CYP51 is the molecular target of the class of drugs referred to as 'azole antifungals'. Mycovia pharmaceuticals initiate enrolment in a phase III trial for the treatment of patients with recurrent vaginal candidiasis (yeast infection). In vitro and in vivo pharmacology studies have demonstrated that the drug is highly active against dermatophytes that cause onychomycosis. Viamet successfully completed phase II clinical trials were was studied the efficacy and safety of oral otesaconazole in patients with onychomycosis of the toenail. In addition, Viamet has completed phase II clinical trial, where was studied the efficacy and safety of otesaconazole in patients with moderate-severe interdigital tinea pedis.
