A Study of RAY1225 at Different Injection Sites in Participants With Different Body Sizes

Phase 1

Completed

• Conditions: Healthy
• Interventions: Drug: RAY1225

• Registration Number: NCT06577428
• Lead Sponsor: Guangdong Raynovent Biotech Co., Ltd

Brief Summary

The purpose of this study is to compare the amount of RAY1225 that gets into the blood stream and how long it takes the body to get rid of it, when injected under the skin of the upper arm and thigh compared to the abdomen. The study will be conducted in healthy males and females with different body sizes. The tolerability of RAY1225 will be evaluated and information about any side effects experienced will be collected. For each participant, the study will last about 7 weeks, including screening.
