Brief Summary:
Multicenter, open-label, randomized, active control study to evaluate efficacy and safety of switching to VM-1500A-LAI + 2NRTIs from the 1st line standard of care therapy for 48 weeks. The 1st part of the study will select one of 2 dose cohorts: 600mg or 900mg.

Condition or disease Intervention/treatment Phase
HIV-1-infection Drug: VM-1500A-LAI Other: Standard of Care Phase 2 Phase 3

Detailed Description:

Eligible patients will be randomized (1:1:1) into 3 treatment groups - LAI 600 (ELPIDA+VM-1500A-LAI 600 mg), LAI 900 (ELPIDA+VM-1500A-LAI 900 mg), and Standard of Care (SoC) therapy. Patients of LAI groups will be assigned by ELPIDA®, 20 mg capsules (and same 2NRTIs) daily therapy for 4 weeks, then one IM injection of 1200 mg VM-1500A-LAI followed by 5 IM monthly injections of 600 mg or 900 mg VM-1500A-LAI QM. When all patients in the VM-1500A-LAI 600mg and VM-1500A-LAI 900 mg dose cohorts complete 24 weeks, the interim analysis will be performed in order to select the dosage regimen for VM-1500A-LAI to continue for additional 28 weeks for a total of 52 weeks of treatment. The analysis will be based on efficacy assessment (number of patients treated with VM1500-LAI who showed the viral load ≥ 50 copies/ml at Week 24 using FDA snapshot algorithm as well as on the basis of a safety and tolerability assessment (assessment of the frequency and severity of AEs associated with the study drug). The optimal dosage regimen will be selected by the IDMC.

4 weeks after the End of Treatment visit, subjects will come for the Follow-up visit.

  4. Stable doses of standard-of-care antiretroviral therapy (NNRTI + 2NRTI) for at least 6 months prior screening;
  5. Serological confirmation of adequate virological suppression within 6 and 12 months before screening as documented by :

    • HIV-1 RNA plasma level < 50 copies/ml at screening;
    • СD4+ Т-cells count ≥ 200 cells/mm3 at screening;
