A 3-part Study of SYX-5219 in Healthy Volunteers and Participants With Atopic Dermatitis
2026년 4월 22일 업데이트: Sitryx Therapeutics Ltd
A Multi-part, FiH Study in Healthy Participants and Participants With Atopic Dermatitis (AD) to Assess the Safety, Tolerability, Pharmacokinetics (PK) of Single & Multiple Ascending Doses and Selected Dose of SYX-5219 (AD Participants).
The purpose of this study is to evaluate the study drug, SYX-5219, in a multi-part First-in-Human (FiH) study to be conducted in healthy volunteers and participants with Atopic Dermatitis (AD). The objectives of this study are to determine the safety, tolerability and levels of SYX-5219 in the blood and urine when SYX-5219 is given in each part of the study (SAD, MAD, Food Effect and Participants with AD).
The study will be split into up to 3 parts as follows:
- Part 1 - Single Ascending Dose (SAD) and Food Effect in healthy volunteers
- Part 2 - Multiple Ascending Dose (MAD) in healthy volunteers
- Part 3 - Multiple Dose in Participants with AD - enrolling up to 45 males and females with a confirmed diagnosis of AD of at least 6 months, evaluating multiple dose administrations of SYX-5219 or placebo daily over a period of 42 days.
연구 개요
상세 설명
This is a multi-part, adaptive, Phase 1, double-blind, first-in-human study to evaluate the safety, tolerability, and pharmacokinetics of SYX-5219 following single ascending doses (SAD), multiple ascending doses (MAD), and selected dosing in participants with atopic dermatitis (AD).
Parts 1 and 2 will be conducted at a single site in the UK. Part 3 will be conducted globally at multiple sites.
Part 1 (Single Ascending Dose & Food Effect) Part 1 (SAD) will enrol up to 48 healthy participants in cohorts (3:1, active:placebo). Participants will receive single doses of SYX-5219, with a food effect evaluation including a second dosing period following washout.
Part 2 (Multiple Ascending Dose) Part 2 (MAD) will enrol up to 24 healthy participants in cohorts (3:1, active:placebo). Participants will receive multiple doses of SYX-5219 over a defined treatment period.
Part 3 (AD Participants) Part 3 will enrol up to 45 participants with AD across multiple global sites. Participants will be randomised (2:1) to receive SYX-5219 or placebo for up to 42 days. Prior exposure to targeted systemic therapy will be limited. Study assessments will include safety and exploratory efficacy evaluations during treatment and follow-up.
