简要总结
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.
详细描述
This project is an international, multicenter, randomized, partially blind clinical study to evaluate efficacy and safety of two different doses of VM-1500 in comparison with Efavirenz added to standard antiretroviral therapy including two NRTIs in treatment-naïve HIV-1-infected patients.
