Resumen

Este es un estudio multicéntrico realizado en participantes que viven con el virus de la inmunodeficiencia humana tipo 1 (VIH-1) que no han sido tratados previamente con ninguna terapia antirretroviral. El estudio investigará dos regímenes de 2 fármacos para el tratamiento del VIH-1: un comprimido oral de combinación a dosis fija de dolutegravir/lamivudina (DTG/3TC) y agentes de acción prolongada cabotegravir más rilpivirina (CAB + RPV LA). Todos los participantes recibirán inicialmente DTG/3TC una vez al día, y una vez alcanzada la supresión virológica (ARN VIH-1 plasmático <50 c/mL), se ofrecerá a los participantes la opción de cambiar a CAB + RPV LA o continuar tomando DTG/3TC oral. Este estudio proporcionará datos importantes sobre la eficacia, seguridad, efectividad de implementación y desenlaces reportados por los pacientes con estos dos regímenes, en un estudio donde los participantes tienen la opción de elegir entre ellos según su preferencia individual. El objetivo del estudio es evaluar la efectividad antiviral a los 11 meses del cambio a CAB+RPV LA tras la supresión virológica inicial con DTG/3TC, y aportar datos sobre el tiempo que tardan los participantes en suprimir su carga viral con DTG/3TC.

Participants with ongoing malignancy other than cutaneous Kaposi's sarcoma, basal cell carcinoma, or resected, non-invasive cutaneous squamous cell carcinoma, or cervical intraepithelial neoplasia; other localized malignancies require agreement between the Investigator and the Medical Monitor for inclusion of the participant prior to enrolment.
Participants with hereditary coagulation and platelet disorders (e.g., haemophilia or von Willebrand Disease); or current or anticipated need for chronic anti-coagulation, with the exception of the use of low-dose acetylsalicylic acid (≤325 mg).
Participants with severe hepatic impairment (Class C) as determined by Child-Pugh classification.
Participants with unstable liver disease as defined by any of the following: presence of ascites, encephalopathy, coagulopathy, hypoalbuminemia, esophageal or gastric varices, or persistent jaundice or cirrhosis, or decompensated cirrhosis (e.g., ascites, encephalopathy, or variceal bleeding), known biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per Investigator assessment).
Participants with history of liver cirrhosis with or without hepatitis viral co-infection.
Participants determined by the Investigator to have a high risk of seizures, including participants with an unstable or poorly controlled seizure disorder. A participant with a prior history of seizure may be considered for enrolment if the Investigator believes the risk of seizure recurrence is low. All cases of prior seizure history should be discussed with the Medical Monitor prior to enrolment.
Participants who, in the Investigator's judgment, pose a significant suicide risk. Participant's recent history of suicidal behavior and/or suicidal ideation should be considered when evaluating for suicide risk.
Participants with signs and symptoms which, in the opinion of the Investigator, are suggestive of active severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection within 14 days prior to enrolment.
Evidence of hepatitis B virus (HBV) infection based on the results of testing at Screening for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), and hepatitis B surface antibody (anti-HBs) as follows:
Participants positive for HBsAg are excluded
Participants negative for HBsAg and negative for anti-HBs but positive for anti-HBc are excluded only if HBV DNA is detected \[either detected below lower limit of quantification (LLOQ); detected above upper limit of quantification (ULOQ); or numerical value (i.e. between LLOQ and ULOQ)\];
Participants negative for HBsAg but positive for anti-HBc and positive for anti-HBs (past and/or current evidence) are immune to HBV and are not excluded.
Participants with hepatitis C virus (HCV) co-infection at Screening are eligible only if:
liver enzymes meet entry criteria; and
HCV disease is not anticipated to require on-study treatment with any agent(s) that have potential adverse drug-drug interactions (DDIs) with the study interventions; and
HCV disease has undergone appropriate work-up and is not advanced or associated with cirrhosis
Participants with untreated syphilis infection (positive rapid plasma reagin \[RPR\] at Screening without clear documentation of completed treatment at least 7 days prior to enrolment) are excluded. Participants with a false positive RPR (with negative treponemal test) or serofast RPR result (persistence of a reactive nontreponemal syphilis test despite history of adequate therapy and no evidence of re-exposure) may enroll after consultation with the Medical Monitor. Participants who completed treatment at least 7 days prior to enrolment are eligible.

Alanine aminotransferase (ALT) ≥5 times the upper limit of normal (ULN); or ALT ≥3xULN and bilirubin ≥1.5xULN (with \>35 percentage (%) direct bilirubin).
Participants known or suspected to have acquired HIV-1 concurrent with use of protease-exposure prophylaxis (PrEP) or post-exposure prophylaxis (PEP) must be discussed with the Medical Monitor prior to enrolment.
