A FIH Study of YH35324 in Atopic Healthy Subjects or Subjects with Mild Allergic Diseases

Phase 1
Completed
Conditions
Atopic Healthy Subjects
Adult Subjects with Mild Allergic Diseases
Interventions
Registration Number
NCT05061524
Lead Sponsor
Yuhan Corporation
Brief Summary

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.

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.

GroupInterventionDescription
YH35324YH35324* Part A: A single dose of the YH35324 will be administered subcutaneously in 5 dose groups (0.3, 1, 3, 6, and 9 mg/kg), and a dose will be escalated in a stepwise manner from low to high doses * Part B: A single dose of the YH35324 will be administered subcutaneously. The dose of YH35324 will be determined after the safety, tolerability, PK, and PD data in Part A are reviewed
PlaceboPlacebo* Part A: A single dose of the Placebo will be administered subcutaneously in 5 Cohorts(Dose groups=0.3, 1, 3, 6, and 9 mg/kg), and a dose will be escalated in a stepwise manner from low to high doses * Part B: Placebo is not administered in Part B
Xolair® for injection (Omalizumab)Omalizumab* Part A: A single fixed dose of the Omalizumab 300mg will be administered subcutaneously in 4 Cohorts(Dose groups of YH35324=1, 3, 6, and 9 mg/kg) * Part B: A single dose of the Omalizumab 300mg will be administered subcutaneously.
