Efficacy, Safety and Optimal Dose of VM-1500 in Comparison to Efavirenz Added to Standard-of-care Antiretroviral Therapy

• Status: Completed
• Trial end date: 2017-09-18
• Target enrollment: 0
• Participant gender: All

Summary

The study is conducted in two stages and open-label stage of the study.

At the first stage of the study, the main purpose was to choose the optimal dose of VM-1500 (20 mg or 40 mg per day) in addition to standard-of-care basic antiretroviral therapy consisting of two NRTIs, in terms of reduction of viral load at Week 12 (<400 copies/ml) in treatment-naïve HIV-1-infected patients.

At the second stage of the study, the main purpose was to evaluate efficacy of VM- 1500 (in the optimal dose selected at the first stage of the study) in comparison to Efavirenz added to standard-of-care antiretroviral therapy of two NRTIs, in terms of reduction of viral load at Week 24 to the undetectable level (<50 copies/ml) in treatment-naïve HIV-1 infected patients.

Open-label stage of the study continued evaluation of viral load and immunological and safety parameters in HIV-1 patients receiving VM-1500 up to Week 96 and additional PK up to Week 100.

4. Clinically stable HIV infection (clinical stages 1 or 2 according to the WHO classification).

5. Indications (in the Investigator's opinion) for ART, according to the WHO Summary Guideline for use of antiretroviral drugs in HIV prevention and treatment (2013).

6. HIV-1 RNA plasma level ≥ 5 000 copies/ml at screening.
