A Study to Compare the Relative Bioavailability of Two Different Formulations of GSK3640254
Study Details
Study Description
Brief Summary
This is a first time in human (FTIH), 2-period study, to assess the relative bioavailability of a mesylate salt capsule of GSK3640254, compared to a bis- hydrochloride salt capsule of GSK3640254, in healthy subjects, administered following a moderate calorie and fat meal. The subjects will be randomized to 2 sequences, Regimen AB or Regimen BA. For Regimen AB: The Regimen A, which will include oral administration of GSK3640254 bis-hydrochloride Capsule 200 milligram (mg) (reference), which will be administered, in Period 1 and Regimen B will include GSK3640254 Mesylate salt capsule (test), 200 mg, which will be administered in Period 2. For the regimen BA, the regimen B, will be administered, in Period 1 and regimen A, in Period 2. Each of the regimens will be given orally as 2 capsules in the morning, as per randomization sequence. There will be a minimum washout of 7 days between each dose of study treatment. A total, of 14 subjects, are planned to be enrolled in the study. The maximum duration of the study from screening to follow-up is approximately 7 weeks.

| Description | Blood samples were collected to analyze the hematology parameters; Hematocrit (Hct), Hemoglobin (Hb), Leukocytes, Lymphocytes, Neutrophils and Platelets. PCI ranges were Hct (Male and Female [high: >0.54 proportion of red blood cells in blood]), Hb (Male and Female [high: >180 grams per liter]), lymphocytes (low: <0.8x10^9 cells per liter), neutrophils (low: <1.5x10^9 cells per liter), platelets (low: <100x10^9 cells per liter and high: >550x10^9 cells per liter) and leukocytes (low: <3x10^9 cells per liter and high: >12x10^9 cells per liter). Participants were counted in the worst case category such that their value changed to (low, normal or high). If values were unchanged (example: High to High), or whose value became normal, were recorded in the 'To Normal or No Change' category. |

| Description | Urine samples were collected to assess urine bilirubin, urine glucose, urine ketones, urine leukocyte esterase (LE), urine nitrite, urine occult blood, urine protein, urobilinogen and monitor urine potential of hydrogen (pH). The dipstick test gave results in a semi-quantitative manner, and results for urinalysis parameters were recorded as negative, trace and positive, indicating proportional concentrations in the urine sample. All the numeric result values >0 have been considered as "positive". |

| Title | Number of Participants With Clinically Significant Abnormal Findings for Electrocardiogram (ECG) Parameters |
|---|---|
| Description | A single 12-lead ECGs was obtained using an ECG machine that automatically calculates the heart rate and measures PR, QRS, QT, QT corrected (QTc) and QT interval corrected for heart rate according to Fridericia's formula (QTcF) intervals. Clinically significant abnormal ranges were: PR: lower: <120 milliseconds (msec) and upper: >200 msec; QRS: lower: <60 msec and upper: >120 msec and QTcF: lower: <320 msec and upper: >450 msec. The number of participants with clinically significant abnormal findings for ECG parameters have been presented. |
