Infection, Human Immunodeficiency Virus Clinical Trial
Official title:
An Evaluation of the Bioequivalence of a Combined Formulated Tablet (50mg/600mg/300mg Dolutegravir/Abacavir/Lamivudine) Compared to One Dolutegravir 50mg Tablet and One EPZICOM† (600mg/300mg Abacavir/Lamivudine) Tablet Administered Concurrently and the Effect of Food on Bioavailability of the Combined Formulation in Healthy Adult Subjects
Dolutegravir (DTG, GSK1349572) is a next-generation integrase inhibitor (INI) currently in phase 3 clinical trials for human immunodeficiency virus (HIV). Fixed-dose combinations (FDCs) have greatly simplified the treatment of patients with HIV. While Atripla (an FDC of tenofovir (TDF), emtricitabine (FTC) and efavirenz (EFV)) has become the preferred first line regimen due in large part to its convenient presentation as a full treatment regimen in a single product, other options are needed. A fixed-dose combination of DTG/abacavir (ABC)/lamivudine (3TC) is one such opportunity. Part A of this study will be a single-dose, two-treatment crossover pivotal bioequivalence (BE) evaluation of the DTG/ABC/3TC FDC tablet in 66 healthy subjects. The reference formulations in this trial will be the 50 mg DTG tablet that is currently being used in the Phase 3 clinical trials and the already marketed FDC tablet product EPZICOM™ (ABC 600 mg/3TC 300 mg).It is intended that the results of this pivotal bioequivalence study will show that the proposed commercial DTG/ABC/3TC FDC tablet formulation is bioequivalent to DTG plus EPZICOM administered as separate tablets. Part B of this study will evaluate the effect of a high fat meal on the FDC tablet in 12 healthy subjects that have already participated in Part A of the study. There will be a screening visit within 30 days prior to the first dose of study drug and a follow up visit within 7-14 days after the last dose. There will be a 7 day washout between doses in each treatment period. The following PK parameters for DTG, ABC and 3TC will be measured: area under the concentration curve from time zero (pre-dose) extrapolated to infinite time (AUC(0-infinity)), Area under the concentration-time curve from time zero (pre-dose) to the time of the last quantifiable concentration (AUC (0-t)), maximum observed concentration (Cmax), lag time before observation of drug concentrations (tlag), time of occurrence of Cmax (tmax), terminal phase half-life (t½), terminal elimination phase rate constant (λz), percentage of AUC obtained by extrapolation (%AUCex),apparent clearance following oral dosing (CL/F) and apparent terminal phase volume
