comparative study of pk and be of vm-1500fdc (fixed-dose combination) and elpida® with truvada® сo-administrated 1 daily fasting in healthy subjects

Conditions: HIV-1-infection

Summary: open-label, randomized, parallel-group, comparative study of pharmacokinetics and bioequivalence of vm-1500fdc (elsulfavirine/emtricitabine/tenofovir fixed-dose combination) and elpida® with truvada® (emtricitabine/tenofovir) co-administered by healthy male subjects. the study will also assess safety profile of study drugs.

the study assesses pk and bioequivalence of the developed new drug vm-1500fdc - a fixed combination of three active substances: elsulfavirine (nnrti), emtricitabine (nrti) and tenofovir (nrti) to elpida® and truvada® co-administered. the combination is intended for once daily administration (1 tablet) for the treatment of hiv-1 infection in adult patients. thus, the purpose of this combination is to simplify the dosage regimen and improve patient compliance
