Sikkerhet, tolerabilitet og farmakokinetikk (PK) undersøkelse av GSK3494245 hos friske deltakere

8. april 2026 oppdatert av: GlaxoSmithKline

En randomisert, dobbeltblind, placebokontrollert, første gang i menneskelig studie for å evaluere sikkerheten, tolerabiliteten og farmakokinetikken til enkeltdoser (i både fødende og fastende stater) av GSK3494245 hos friske deltakere

Dette er en fase 1, dobbeltblind, randomisert, placebokontrollert, første gang i human (FTIH) studie for å vurdere sikkerheten, toleransen og PK av en enkeltdose GSK3494245. Studien vil bestå av 3 kohorter, utført på en sekvensiell måte. Kohorter 1 og 2 vil bestå av en enkelt stigende dose (SAD), crossover-design hvor hver deltaker vil motta maksimalt 3 stigende orale doser GSK3494245 og 1 placebodose under fastende forhold. Ved hvert dosenivå vil GSK3494245 og placebo bli administrert i forholdet 3:1, innenfor hver periode, i henhold til randomiseringsplanen på en blind måte. Kohort 3 vil bestå av en 2-veis crossover som inkluderer 1 doseringsregime under fastende betingelser og 1 regime under fôring og deretter fastende forhold i forholdet 1:1. Fôringsforholdene vil undersøke effekten av sikkerhet, tolerabilitet og PK av en enkelt dose GSK3494245 etter matadministrasjon.

Forhold

Detaljert beskrivelse

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.

If no Day 1 assessments were available, the most recent data from Day -1 or screening was used. If all pre-dose data were missing, no derivation was performed, and Baseline was set to missing. Change from baseline value is defined as post-dose value minus baseline value. Standard deviation (SD)=0.0000 is defined as SD resulted below the detectable limit of the assay and approximate to 0.0000.
