Inclusion criteria
Inclusion criteria: 1) Willing and able to provide written informed consent 2) Adult aged = 18 years (at all sites) or adolescent aged = 12 and weighing = 35 kg (at sites in North America and Dominican Republic) 3) Are receiving a stable failing ARV regimen for > 8 weeks before Screening and willing to continue the regimen until Day 1. Participants in Cohort 1 must also be willing to continue the failing regimen until completing the Functional Monotherapy Period (Day 1 to Day 14) 4) Have HIV-1 RNA = 400 copies/mL at Screening 5) Have screening or available historical HIV resistance reports showing resistance to = 2 antiretroviral medications from each of = 3 of the 4 main classes of antiretroviral medications (NRTI, NNRTI, PI, INSTI). Resistance to FTC or 3TC associated with the presence of the M184V/I RT mutation cannot be used for the purpose of determining this eligibility criterion 6) Have = 2 fully active ARV remaining from the 4 main classes that can be effectively combined to form a viable regimen in the opinion of the investigator based on resistance, tolerability, contraindication, safety, drug access, or acceptability to the participant 7) Able and willing to receive an optimized background regimen together with GS-6207. Participants with an OBR without a fully active agent may be enrolled if the investigator considers that there is a favorable risk-benefit ratio for the participant. With prior approval from Gilead Sciences, components of the OBR may be investigational (ie not-yet-approved) 8) A negative serum pregnancy test is required for all women at Screening 9) Men and women of childbearing potential who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception 10) Lactating women must agree to discontinue nursing before administration of GS-6207 Are the trial subjects under 18? yes Number of subjects for this age range: 15 F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 70 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 15
Exclusion criteria
Exclusion criteria: 1) An opportunistic illness requiring acute therapy within the 30 days prior to screening 2) Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days before screening 3) Active tuberculosis infection 4) Acute hepatitis within 30 days prior to Screening visit 5) Untreated or newly treated ( LLOQ 7) A history of or current clinical decompensated liver cirrhosis (eg ascites, encephalopathy, or variceal bleeding) 8) Treatment within three months prior to screening, or anticipated treatment during the study period with immunosuppressant therapies, hydroxyurea, foscarnet, radiation, or cytotoxic chemotherapeutic agents without prior approval from Sponsor prior to randomization 9) Active malignancy requiring acute therapy (with the exception of local cutaneous Kaposi's sarcoma) 10) Current alcohol or substance use judged by the Investigator to potentially interfere with the participant’s study compliance 11) Clinically significant abnormal ECG at the Screening visit 12) Any of the following laboratory values at screening: a. Estimated GFR = 50 mL/min using Cockcroft-Gault formula for participants = 18 years of age Cockcroft and Schwartz Formula for participants 5 x upper limit of normal (ULN) c. Direct bilirubin > 1.5 x ULN d. Platelets < 50,000/mm3 e. Hemoglobin < 8.0 g/dL 13) Participation or planned participation in any other clinical trial (including observational trials) without prior approval from the sponsor throughout the study 14) Prior use of, or exposure to, GS-6207 15) Known hypersensitivity to the IMP, the metabolites, or formulation excipient 16) Use or planned use of exclusionary medications. 17) Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the participant unsuitable for the study or unable to comply with dosing requirements
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the antiviral activity of GS-6207 administered as an add-on to a failing regimen (functional monotherapy) for PLWH with MDR as determined by the proportion of participants achieving at least 0.5 log10 reduction from baseline in HIV-1 RNA at the end of Functional Monotherapy Period;Secondary Objective: To evaluate the safety and efficacy of GS-6207 in combination with an optimized background regimen at Weeks 26 and 52;Primary end point(s): The proportion of participants in Cohort 1 achieving = 0.5 log10 copies/ml reduction from baseline in HIV-1 RNA at the end of Functional Monotherapy Period ;Timepoint(s) of evaluation of this end point: End of Functional Monotherapy Period | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The proportion of participants in Cohort 1 with plasma HIV-1 RNA < 50 copies/mL and < 200 copies/mL at Weeks 26 and 52 treatment based on the US FDA-defined snapshot algorithm;Timepoint(s) of evaluation of this end point: Weeks 26 and 52 of treatment | — |
