Study of HXN6005 in Healthy Participants and Patients With Moderate-to-Severe Atopic Dermatitis
A Phase I/II, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Efficacy of HXN6005 in Healthy Participants and Patients With Moderate-to-Severe Atopic Dermatitis
This is a Phase I/II, multicenter, randomized, double-blind, placebo-controlled study evaluating HXN6005 in healthy participants and patients with moderate-to-severe atopic dermatitis (AD).
The study consists of three parts: Part A (single ascending dose in healthy participants), Part B (multiple ascending dose in AD patients), and Part C (multiple-dose efficacy and safety assessment in AD patients).
The primary objectives are to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), and preliminary efficacy of HXN6005.

Detaillierte Beschreibung
Part A (Single Ascending Dose, SAD) is a randomized, double-blind, placebo-controlled, single-dose escalation design conducted in healthy participants. It includes two sequential dose cohorts. A total of 16 healthy participants are planned, with 8 participants per cohort (6 receiving HXN6005 and 2 receiving placebo). Participants receive a single subcutaneous injection of HXN6005 or placebo. All participants are followed for safety, PK, PD, and anti-drug antibody (ADA) assessments.
Part B (Multiple Ascending Dose, MAD) is a randomized, double-blind, placebo-controlled study conducted in patients with moderate-to-severe AD. Part B enrolls 16 patients across two dose cohorts, with 8 patients per cohort (6 receiving HXN6005 and 2 receiving placebo). Patients receive multiple subcutaneous injections of HXN6005 or placebo according to the study schedule.
Part C is a multicenter, randomized, double-blind, placebo-controlled study conducted in patients with moderate-to-severe AD. A total of 35 patients are planned to be randomized into two HXN6005 dose groups and one placebo group, receiving multiple subcutaneous doses according to the study schedule. Regular follow-up visits are conducted to collect efficacy data, safety data, and blood samples for assessment of systemic exposure, immunogenicity, and biomarkers.
