Study Details

Study Description

Brief Summary

This study will be conducted in two Parts to confirm the acceptability/selection of a tablet formulation for future clinical development of GSK2838232. Part 1 of the study will assess single ritonavir (RTV)-boosted doses of a new tablet formulation given with food (containing approximately 30% fat) against the reference capsule formulation also given with food and then will assess the impact of fasted conditions on the tablet performance. In Part 2, non-boosted GSK2838232 will be given as once-daily tablet doses for 11 days in a separate group of subjects, assuming the tablet performance is considered acceptable from Part 1. Approximately 16 healthy subjects will be enrolled to provide at least 12 evaluable subjects through the three study periods in Part 1. 10 healthy subjects will be enrolled to provide at least 8 evaluable subjects through the single study period in Part 2. The maximum duration of study participation will be approximately 9 to 10 weeks for Part 1; and 8 to 9 weeks for Part 2.

Title Part 2: Number of Participants With Worst Case Urinalysis Results Relative to Normal Range Criteria
Description Urine samples were collected from participants for analysis of following urinalysis parameters; specific gravity, potential of hydrogen (pH), presence of glucose, protein, occult blood, ketones in urine analyzed by dipstick method. The dipstick test gives results in a semi-quantitative manner. Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. The reference range is 1.002-1.030. Urine pH is an acid-base measurement. Normal urine has a slightly acid pH (5.0 - 6.0). Participants were counted in the worst case category that their value changes to (low, normal or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (e.g., High to High), or whose value became normal, were recorded in the "To Normal or No Change" category.

Title Part 2: Number of Participants With Abnormal Electrocardiogram (ECG) Findings
Description Single and triplicate 12-lead ECG's were obtained at least 5 minutes apart in the supine position after 10 minutes of rest at indicated time points using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT and QT duration corrected for heart rate by Fridericia's formula (QTcF) intervals. Clinically significant (CS) and not clinically significant (NCS) abnormal ECG findings have been presented. CS abnormal findings are those which are not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition.
Time Frame Day -1; 1, 4, 12 hours on Day 1; Days 2, 3, 5, 8; 1, 4, 12, 24 Hours on Day 11; Follow-up (Day 25)

Title Part 1: Number of Participants With Worst Case Urinalysis Results Relative to Normal Range Criteria
Description Urine samples were collected from participants for analysis of following urinalysis parameters; specific gravity, pH, presence of glucose, protein, occult blood, ketones in urine analyzed by dipstick method. The dipstick test gives results in a semi-quantitative manner. Urine specific gravity is a measure of the concentration of solutes in the urine and provides information on the kidney's ability to concentrate urine. The reference range is 1.002-1.030. Urine pH is an acid-base measurement. Normal urine has a slightly acid pH (5.0 - 6.0). Participants were counted in the worst case category that their value changes to (low, normal or high), unless there is no change in their category. Participants whose laboratory value category was unchanged (e.g., High to High), or whose value became normal, were recorded in the "To Normal or No Change" category.

CS and NCS abnormal ECG findings have been presented. CS abnormal findings are those which are not associated with the underlying disease, unless judged by the investigator to be more severe than expected for the participant's condition.
