About this trial

This is an interventional treatment trial for HIV-1-infection

Eligibility Criteria

18 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria: Have a confirmed HIV-1 infection in the documented medical record or at screening Have never received antiretroviral therapy (ART) after diagnosis of HIV-1 infection; Participants with a history of PrEP or PEP therapy are eligible for inclusion (except for monoclonal antibodies, maturation inhibitors, and INSTIs, such as cabotegravir) if they have discontinued therapy at least 8 weeks prior to screening Exclusion Criteria: Have a hepatitis B surface antigen or positive hepatitis C virus antibody at screening. An HCV confirmation (HCV RNA test) will be performed at a central laboratory if the HCV antibodies screening result is positive. If the HCV RNA test result is negative, the participant will be eligible. Have a positive drug screen for amphetamines, barbiturates, cocaine, opiates, benzodiazepines, heroin, or phencyclidine Have a history of regular alcohol consumption, defined as an average weekly intake of more than14 drinks (for males) or more than 7 drinks (for females), within 6 months of screening Have received the following antiretrovirals (ARVs): monoclonal antibodies, maturation inhibitors, and INSTIs (such as cabotegravir) used as PEP or PrEP Pregnant or lactating females Have a history of clinically relevant pancreatitis or hepatitis within the previous 6 months

Outcomes

Primary Outcome Measures

HIV-1 RNA copies change in plasma
Ratio of change in plasma HIV-1 RNA from baseline to Day 11 following a 10-day treatment period at each dose level.
Total Number of Adverse Events (AEs) occurring through Day 11
Cumulative number of AEs occurring from Day 1 through Day 11 at each dose level and placebo in treatment-naïve adults with HIV-1 infection, regardless of treatment discontinuation, and use of prohibited medications. The severity of the AE will be rated as per the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events Corrected Version 2.1, July 2017. These will be descriptively summarized.
Total Number of Serious Adverse Events (SAEs) occurring through Day 11
Cumulative number of SAEs occurring from Day 1 through Day 11 at each dose level and placebo in treatment-naïve adults with HIV-1 infection, regardless of treatment discontinuation, use of prohibited medications, and death are included in the endpoint. These will be descriptively summarized.
Mean area under the concentration-time curve from zero to 24 hours (AUC0-24h)
Mean observed maximum concentration after administration (Cmax)
Mean time to reach Cmax (Tmax)
Mean observed concentration at 24 hours after administration (C24h)
Mean area under the concentration-time curve to infinite time (AUCinf)
Mean area under the concentration-time curve to time t (AUCt)
Mean terminal half-life (t1/2)
Mean apparent oral clearance (CL/F)
Mean apparent volume of distribution (Vd/F)

Secondary Outcome Measures

HIV-1 RNA copies change in plasma from baseline to post-dose timepoints
HIV-1 RNA change in plasma from baseline to nadir over 11 days.
Plasma HIV-1 RNA rate of decline over 11 days
Number of participants with HIV-1 RNA <400 copies/mL
descriptive statistics.
Number of participants with HIV-1 RNA <50 copies/mL
CD4+ cell count change
STP0404 exposure-efficacy relationship in plasma HIV-1 RNA copies / CD4+ cell count
Emergence of drug resistance mutations.
