Investigación de seguridad, tolerabilidad y farmacocinética (PK) de GSK3494245 en participantes sanos

8 de abril de 2026 actualizado por: GlaxoSmithKline

Un estudio aleatorizado, doble ciego, controlado con placebo, por primera vez en humanos para evaluar la seguridad, la tolerabilidad y la farmacocinética de dosis únicas (tanto en estado de alimentación como en ayunas) de GSK3494245 en participantes sanos

Este es un estudio de Fase 1, doble ciego, aleatorizado, controlado con placebo, por primera vez en humanos (FTIH) para evaluar la seguridad, la tolerabilidad y la PK de una dosis única de GSK3494245. El estudio constará de 3 cohortes, realizadas de manera secuencial. Las cohortes 1 y 2 consistirán en un diseño cruzado de dosis única ascendente (SAD) en el que cada participante recibirá un máximo de 3 dosis orales ascendentes de GSK3494245 y 1 dosis de placebo en ayunas. En cada nivel de dosis, GSK3494245 y el placebo se administrarán en una proporción de 3:1, dentro de cada período, de acuerdo con el programa de aleatorización de forma ciega. La cohorte 3 comprenderá un cruce de 2 vías que incluye 1 régimen de dosificación en condiciones de ayuno y luego alimentación y 1 régimen en condiciones de alimentación y luego ayuno en una proporción de 1:1. Las condiciones de alimentación investigarán el efecto de seguridad, tolerabilidad y farmacocinética de una dosis única de GSK3494245 después de la administración de alimentos.

Descripción detallada

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.

Summary of Change From Baseline in Hematology Parameters: Basophils, Neutrophils, Eosinophils, Lymphocytes, Monocytes and Platelets
Periodo de tiempo: At Day 2 and Day 4 in each treatment period compared to Baseline
Blood samples were collected for the assessment of the hematology parameters: basophils, neutrophils, eosinophils, lymphocytes, monocytes and platelets. Baseline was defined as the last non-missing pre-dose assessment for each cohort. In general, assessments on Study Day 1 taken before the first dose were used as Baseline.

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.

Blood samples were collected for the assessment of the clinical chemistry parameters: CRP. Baseline was defined as the last non-missing pre-dose assessment for each cohort. In general, assessments on Study Day 1 taken before the first dose were used as Baseline. If multiple assessments were captured on Day 1 but the time of the first assessment was missing, the first recorded assessment was used. If only one Day 1 assessment lacked timing, the last available assessment from Day -1 or earlier was used. 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. SD=0.0000 is defined as SD resulted below the detectable limit of the assay and approximate to 0.0000.
