Brief Summary

This is a two parts study, a single ascending dose followed by 14-days repeat dosing. The single ascending dose part will assess two dose levels of GSK3923868 or placebo across two treatment periods 1 and 2 in a single cohort of participants with a washout period of a minimum of 5 days after each treatment periods. The repeat dose part will assess repeated one dose level of GSK3923868 or placebo in treatment period 3 with up to 14 days of follow up in the same cohort of participants. The duration of study participation for treatment period 1, 2 and 3 will be 6, 6 and up to 29 days (including follow up), respectively.

Outcome Measures

Primary Outcomes (9)

• Number of Participants With Non-serious Adverse Events (Non-SAEs) and Serious Adverse Events (SAEs) Following Single Dose of GSK3923868

  An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is 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 or significant disability/incapacity, is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment. Adverse events which were not serious, were considered as non-serious adverse events.

  Up to 18 days

• Number of Participants With Non-SAEs and SAEs Following Repeat Dose of GSK3923868

  An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. An SAE is 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 or significant disability/incapacity, is a congenital anomaly/birth defect or any other situation according to medical or scientific judgment.

Tympanic Temperature was also measured as a vital sign but did not require positioning or rest prior to measuring. Twelve-lead electrocardiogram were performed in a semi-supine position after at least 10 minutes rest using an ECG machine that automatically calculates the heart rate and measures PR interval, QRS duration, QT and corrected QT intervals (QTc) intervals. Number of participants with clinically significant changes in vital signs and ECG parameters were reported. Clinical significance was determined by the investigator.
