Brief Title  ICMJE Study to Evaluate Efficacy and Safety of Switching to VM-1500A-LAI + 2NRTIs From the 1st Line Standard of Care Therapy
Official Title  ICMJE 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
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.
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.

Eligibility Criteria  ICMJE

Inclusion Criteria:

  1. Signed Patient Information Sheet and Informed Consent Form

  3. HIV-1 infection confirmed serologically by ELISA or immunoblot analysis (or documented HIV-1 infection);
  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;
  6. Adequate organ function as documented by laboratory test results;
  7. Female patients must be postmenopausal not less than 2 years, surgically sterile, or if of child-bearing potential, must use two reliable forms of contraception from screening to 3 months after the end of dosing; two reliable forms of contraception include use of condom with spermicide by male partner, or diaphragm with spermicide, or condom use by male partner and diaphragm, or condom use by male partner and non-hormonal intrauterine device.
  8. Male patients must use two reliable forms of contraception from screening to 3 months after the end of dosing; two reliable forms of contraception include condom with spermicide, or diaphragm use by female partner with spermicide, or condom and diaphragm use by female partner, or condom and intrauterine device use by female partner.

  1. Acute hepatitis or cirrhosis of the liver of any etiology; HBsAg or antibodies to hepatitis C (in the case of Anti-HCV +, the exclusion criterion must be confirmed by determining a positive HCV RNA test) at screening;
