a clinical trial of gsk3640254 + dolutegravir (dtg) in human immunodeficiency virus-1 infected treatment-naive adults

Conditions: HIV Infections

Summary: the purpose of this study was to evaluate the efficacy of gsk3640254 + dtg relative to lamivudine (3tc) + dtg in treatment-naïve adult participants living with human immunodeficiency virus (hiv)-1. the participants were randomized to one of the three doses of blinded gsk3640254 (100, 150, or 200 milligrams \[mgs\]) or a reference arm of blinded 3tc-each in combination with open label dtg.


Eligibility criteria:
inclusion criteria: * treatment-naive, defined as no anti-retrovirals (arvs) (in combination or monotherapy) received after a known diagnosis of hiv-1 infection. * documented hiv infection and screening plasma hiv-1 rna greater than or equal to (\>=)1000 c/ml. * screening cd4+ t-cell count \>=250 cells per millimeter\^3 (cells/cubic millimeter). * body weight \>=50.0 kilograms (kg) (110 pounds \[lbs.\]) for men and \>=45.0 kg (99 lbs.) for women and body mass index (bmi) \>18.5 kilograms per meter\^2 (kg/meter square). calculations will utilize sex assigned at birth. exclusion criteria: * any evidence of an active centers for disease control and prevention (cdc) stage 3 disease \[cdc, 2014\], except cutaneous kaposi's sarcoma not requiring systemic therapy. * presence of primary hiv infection, evidenced by acute retroviral syndrome (example \[e.g.\], fever, malaise, fatigue, etc.) and/or evidence of recent (within 3 months) documented viremia without antibody production and/or evidence of recent (within 3 months) documented seroconversion. * 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), known biliary abnormalities (with the exception of gilbert's syndrome or asymptomatic gallstones or otherwise stable chronic liver disease per investigator assessment); * history of ongoing or clinically relevant hepatitis within the previous 6 months. * any history of significant underlying psychiatric disorder. * any history of major depressive disorder with or without suicidal features, or anxiety disorders, that required medical intervention (pharmacologic or not) such as hospitalization or other inpatient treatment and/or chronic (\>6 months) outpatient treatment. * a pre-existing condition, in the opinion of the investigator or medical monitor, that could interfere with normal gastrointestinal anatomy or motility (e.g., gastroesophageal reflux disease \[gerd\], gastric ulcers, gastritis, inflammatory bowel disease), hepatic and/or renal function, or with the absorption, metabolism, and/or excretion of the study interventions or render the participant unable to take oral study treatment. * familial or personal history of long qt syndrome or sudden cardiac death. * active treatment for a viral infection other than hiv-1, such as hepatitis b, with an agent that is active against hiv-1 (were known to be infected with hiv-1 after treatment for hepatitis b was completed). * participants who require concomitant medications known to be associated with a prolonged corrected qt (qtc) interval. * exposure to an experimental drug, human blood product, monoclonal antibody, or vaccine (which does not have emergency, conditional, or standard market authorization) within 28 days prior to the first dose of study treatment.
