Brief summary

This study is the first to test GSK3494245 in humans, to evaluate its safety, tolerability, and pharmacokinetics (PK) after a single dose. It involves 3 groups of participants and has a crossover design where each participant received a maximum of 3 ascending oral doses of GSK3494245 and 1 placebo dose under fasted conditions. The first 2 Cohorts received up to 3 increasing doses of the drug and 1 dose of a placebo under fasted conditions, within each period, according to the randomization schedule, in a blinded manner. Cohort 3 is comprised of a 2-way crossover which includes 1 dosing regimen under fasted then fed conditions and 1 regimen under fed then fasted conditions in a 1:1 ratio.

Detailed description

The study originally planned to include 2 parts - a single ascending doses (SAD) part and a multiple ascending doses (MAD) part, incorporating a food effect component to investigate the influence of food on the PK of GSK3494245. However, only the SAD part was conducted due to a decision to terminate the study early.
