About

This study will assess the effect of food on the pharmacokinetics (PK) of pediatric formulations of TRIUMEQ (dolutegravir [DTG] 5 milligrams [mg]/abacavir [ABC] 60 mg/lamivudine [3TC] 30 mg) dispersible tablets and DOVATO (DTG 5 mg/3TC 30 mg) dispersible tablets in healthy adult participants. Additionally, safety and tolerability of these formulations will also be assessed. TRIUMEQ and DOVATO are registered trademarks of GlaxoSmithKline group of companies.

Enrollment: 33 patients

Sex: All

Ages: 18 to 50 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participant must be 18 to 50 years of age inclusive, at the time of signing the informed consent.
• Participants who are healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, and cardiac monitoring (history and ECG).
• Body weight >=50.0 kilograms (kg) (110 pounds [lbs.]) for males and >=45 kg (99 lbs.) for females and body mass index within the range 18.5 to 31.0 kilogram per meter square (kg/m^2, inclusive).
• A male participant is eligible to participate if they agree to use contraceptive methods.
• A female participant is eligible to participate if she is not pregnant (, not lactating or breastfeeding, and at least 1 of the following conditions applies: Is not a woman of childbearing potential (WOCBP) OR Is a WOCBP and using a non-hormonal contraceptive method that is highly effective
• Capable of giving signed informed consent
• Documentation that the participant is negative for the human leukocyte antigen (HLA) B*5701 allele.

Exclusion criteria

• Current or chronic history of liver disease or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones).
• Medical history of cardiac arrhythmias, prior myocardial infarction in the past 3 months, or cardiac disease or a family or personal history of long QT syndrome.
• A pre-existing condition interfering with normal gastrointestinal anatomy or motility (e.g., gastroesophageal reflux disease, gastric ulcers, gastritis), hepatic and/or renal function, that could interfere with the absorption, metabolism, and/or excretion of the study intervention.
• QT interval corrected for heart rate according to Fridericia's formula (QTcF) >450 milliseconds (msec).
• A participant with known or suspected active coronavirus disease (COVID-19) infection OR contact with an individual with known COVID-19, within 14 days of study enrollment.
• Presence of hepatitis B surface antigen at screening or within 3 months prior to starting study intervention.
• Positive hepatitis C antibody test result at screening or within 3 months prior to starting study intervention AND positive on reflex to hepatitis C ribonucleic acid (RNA).
• Positive human immunodeficiency virus (HIV)-1 and -2 antigen/antibody immunoassay at screening.
• Alanine aminotransferase (ALT) >1.5 × upper limit of normal (ULN). A single repeat of ALT is allowed within a single screening period to determine eligibility.
• Bilirubin >1.5 × ULN (isolated bilirubin >1.5 × ULN is acceptable if bilirubin is fractionated and direct bilirubin <35%). A single repeat of any laboratory abnormality is allowed within a single screening period to determine eligibility.
• Any acute laboratory abnormality at screening which, in the opinion of the investigator, should preclude participation in the study of an investigational compound.
• Any Grade 2 to 4 laboratory abnormality at screening, with the exception of creatine phosphokinase (CPK) and lipid abnormalities (e.g., total cholesterol, triglycerides), and ALT (described above), will exclude a participant from the study unless the investigator can provide a compelling explanation for the laboratory result(s) and has the assent of the sponsor. A single repeat of any laboratory abnormality is allowed within a single screening period to determine eligibility.
• A positive test result for drugs of abuse (including marijuana), alcohol, or cotinine (indicating active current smoking) at screening or before the first dose of study intervention.
• Unable to refrain from the use of prescription or non-prescription drugs including vitamins, herbal and dietary supplements (including St. John's wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study intervention and for the duration of the study until completion of the follow-up visit, unless, in the opinion of the investigator and ViiV Healthcare (VH)/GlaxoSmithKline medical monitor, the medication will not interfere with the study procedures or compromise participant safety.
• Unwillingness to abstain from excessive consumption of any food or drink containing grapefruit and grapefruit juice, Seville oranges, blood oranges, or pomelos or their fruit juices within 7 days prior to the first dose of study intervention(s) until the end of the study.
• Participation in another concurrent clinical study or prior clinical study (with the exception of imaging trials) prior to Day 1 of Period 1 in the current study: 30 days, 5 half-lives, or twice the duration of the biological effect of the study intervention (whichever is longer).
• Where participation in the study would result in donation of blood or blood products in excess of 500 milliliter (mL) within 60 days.
• Estimated serum creatinine clearance (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI]) <90 milliliter per minute (mL/min).
• History of regular alcohol consumption within 6 months of the study, defined as an average weekly intake of >14 units for males or >7 drinks for females.
• Unable to refrain from tobacco or nicotine-containing products within 1 month prior to screening.
• History of sensitivity, prior intolerance or hypersensitivity to any of the study interventions, or components thereof, or a history of drug or other allergy that, in the opinion of the investigator or medical monitor, contraindicates their participation.

Experimental group

Description:

Participants received TRIUMEQ (dolutegravir \[DTG\] 5 milligram \[mg\]/abacavir \[ABC\] 60 mg/lamivudine \[3TC\] 30 mg), dispersible tablets administered as a dispersion immediately after a high calorie meal (under fed condition) (Treatment A) in treatment period 1 followed by TRIUMEQ (DTG 5 mg/ABC 60 mg/3TC 30 mg), dispersible tablets administered as a dispersion under fasted conditions (Treatment B) in treatment period 2.
