Veiligheid, verdraagbaarheid en farmacokinetiek (PK) Onderzoek van GSK3494245 bij gezonde deelnemers

8 april 2026 bijgewerkt door: GlaxoSmithKline

Een gerandomiseerde, dubbelblinde, placebo-gecontroleerde, eerste keer in onderzoek bij mensen om de veiligheid, verdraagbaarheid en farmacokinetiek van enkelvoudige (in zowel gevoede als nuchtere) doses van GSK3494245 bij gezonde deelnemers te evalueren

Dit is een fase 1, dubbelblinde, gerandomiseerde, placebogecontroleerde, first time in human (FTIH) studie om de veiligheid, verdraagbaarheid en PK van een enkele dosis GSK3494245 te beoordelen. Het onderzoek zal bestaan ​​uit 3 cohorten, die opeenvolgend worden uitgevoerd. Cohorten 1 en 2 zullen bestaan ​​uit een enkele oplopende dosis (SAD), crossover-ontwerp waarbij elke deelnemer maximaal 3 oplopende orale doses van GSK3494245 en 1 placebodosis onder nuchtere omstandigheden krijgt. Op elk dosisniveau zullen GSK3494245 en placebo worden toegediend in een verhouding van 3:1, binnen elke periode, volgens het randomisatieschema op een geblindeerde manier. Cohort 3 zal bestaan ​​uit een 2-weg cross-over, bestaande uit 1 doseringsregime onder nuchtere dan gevoede condities en 1 regime onder gevoede dan nuchtere condities in een verhouding van 1:1. De gevoede omstandigheden zullen het effect van veiligheid, verdraagbaarheid en PK van een enkele dosis GSK3494245 na voedseltoediening onderzoeken.

Gedetailleerde beschrijving

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.
