- Brief Summary
This is an open-label, randomized, crossover study in healthy adult subjects with 5 treatment groups over 5 dosing periods. This study will evaluate pharmacokinetic parameters and relative bioavailability of a dispersible, fixed-dose combination (FDC) tablet of TRIUMEQ™ (\[abacavir, ABC\]/\[dolutegravir, DTG\]/\[lamivudine, 3TC\]) when dispersed and consumed under four different dosing conditions in comparison to an oral dose of TIVICAY™ (DTG) + EPZICOM™ (ABC/3TC) non-dispersible tablets administered in the fasted state. Approximately 20 subjects will be randomized, each to one of 5 treatment groups. The total duration of participation of a subject in this study will be approximately 10-11 weeks. It will include a screening visit within 30 days prior to the first dose of study drug, five treatment periods each with a single dose of study drug per treatment period and a follow up visit within 7 10 days after the last dose. There will also be a washout of at least 7 days between doses in each treatment period. TRIUMEQ, EPZICOM, and TIVICAY are trademarks of the GlaxoSmithKline group of companies.

Number of subjects with adverse event (AE) and serious adverse event (SAE). Approximately 11 weeks AE is any untoward medical occurrence in a patient or clinical investigation subject, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a medicinal product. Any untoward event resulting in death, life threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, congenital anomaly/birth defect or any other situation according to medical or scientific judgment will be categorized as SAE.
Blood pressure assessment as a safety measure Approximately 11 weeks Systolic and diastolic blood pressure will be measured in supine or semi-supine position after 5 minutes rest at Day -1, pre-dose, 4h, 24h, 48 h, 72h post-dose, and at follow up
Measurement of pulse rate as a safety measure Approximately 11 weeks Heart rate will be measured at supine or semi-supine position after 5 minutes rest at Day -1, pre-dose, 4h, 24h, 48 h, 72h post-dose, and at follow up
Body temperature assessment as a safety measure Approximately 11 weeks Temperature will be recorded at supine or semi-supine position after 5 minutes rest at Day -1, pre-dose, 4h, 24h, 48 h, 72h post-dose, and at follow up
Electrocardiogram (ECG) assessment as a measure of safety Approximately 11 weeks Single 12-lead ECGs will be obtained in a supine or semi-supine position having rested in this position for at least 10 minutes beforehand at Day -1 of each of 5 treatment periods
Number of subjects having abnormal clinical laboratory parameters as a measure of safety Approximately 11 weeks Blood samples will be collected (at Day -1, and 24 h post-dose and at follow-up if needed) to analyze blood urea nitrogen, creatinine, glucose, creatine phosphokinase (CPK), sodium, potassium, calcium, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), total bilirubin, direct bilirubin, total protein, albumin
Number of subjects having abnormal hematology laboratory parameters as a measure of safety Approximately 11 weeks Blood samples will be collected (at Day -1 and 24h post-dose and at follow-up if needed) to analyze platelet count, Red Blood Cells (RBC) count, hemoglobin, hematocrit, mean corpuscular volume ( MCV), mean corpuscular hemoglobin (MCH) White Blood Cells (WBC), neutrophils, lymphocytes, monocytes, eosinophils, and basophils
Number of subjects having abnormal urinalysis as a measure of safety Approximately 11 weeks Urine samples will be collected (at Day -1, and 24 h post-dose and at follow-up if needed) to analyze specific gravity, pH, glucose, protein, blood and ketones by dipstick, and for microscopic examination
