Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) following a single subcutaneous injection of YH35324 in subjects with various allergic diseases.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This drug(YH35324) is currently under development as a novel therapeutic agent for various IgE-mediated allergic diseases. Since YH35324 exhibits high binding affinity to human IgE, it prevents serum IgE from binding to receptors on mast cells and basophils, thereby inhibiting histamine release via degranulation following allergen exposures. In addition, YH35324 suppresses autoantibody-dependent effector cell activation by blocking anti-FcεRIα autoantibodies. This study aims to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) following a single subcutaneous injection of YH35324 in subjects with various allergic diseases.

QUADRUPLE

Participants Caregivers Investigators Outcome Assessors
Each IP will be labeled with a unique IP number, and the number will be associated with the randomized treatment group. Interactive Web Response System (IWRS) will be used to assign a randomization number and IP number.

As YH35324, placebo, and omalizumab differ in appearance, the assigned treatment group of subjects should be disclosed to study pharmacists and unblinded staff who prepare (taking an appropriate and correct amount (mL) of the IP based on the subject's body weight into a syringe), dispense, and administer the IPs, in order to maintain the blind. Therefore, the treatment group information of subjects will be checked through IWRS with limited access before administration of the IP, and only study pharmacists and unblinded staff are allowed to access the system.

The study pharmacists and unblinded staff should not disclose the assigned treatment group of enrolled subjects to the principal investigator or study staff.
