November 28, 2024 updated by: Yuhan Corporation

A First-in-Human, Randomized, Double-Blind, Placebo/Active Controlled, Single Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics Following Subcutaneous Injections of YH35324 in Atopic Healthy Subjects or Subjects with Mild Allergic Diseases

The purpose of this study is to evaluate the safety, tolerability, PK, and PD following subcutaneous injections of YH35324 in atopic healthy subjects or adult subjects with mild allergic diseases. Eligible subjects will be randomized to the YH35324 group, the placebo group, or the omalizumab group.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

YH35324 is a drug under development as a novel therapeutic agent for various IgE-mediated allergic diseases. Since YH35324 has a high binding affinity to human IgE, it prevents serum IgE from binding to receptors on mast cells and basophil, thereby inhibiting histamine release caused by degranulation when exposed to allergens Based on its non-clinical study results, this study aims to evaluate the safety, tolerability, PK, and PD following subcutaneous injections of YH35324 in atopic healthy subjects or subjects with mild allergic diseases.
