Details and patient eligibility

About

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.

Enrollment: 48 patients

Sex: All

Ages: 18 to 50 years old

Volunteers: Accepts Healthy Volunteers
