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.

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.

Number of Participants With Non-serious Adverse Events (Non-SAEs) and Serious Adverse Events (SAEs)

An adverse event (AE) is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE is defined as any untoward medical occurrence that, at any dose, results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent disability/incapacity, is a congenital anomaly/birth defect and other situations according to medical or scientific judgement.

Number of Participants With Worst Case Hematology Results by Potential Clinical Importance (PCI) Criteria

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.

Time frame: Up to 22 days
