Randomized Phase I Study Comparing Bioavailability and Safety of SHR-3167 Injection in Healthy Adults Aged 18 to 55

What this Trial Is About

Researchers are conducting a Phase I clinical trial to compare the bioavailability and safety of different forms of SHR-3167 injection in healthy adults between 18 and 55 years old. This study aims to understand how the drug is absorbed and processed in the body, focusing on the maximum plasma concentration and overall exposure to the drug over time. Participants will receive one of three different specifications of SHR-3167 injection in a randomized, parallel, and open-label design. The study will monitor the drugs levels in the blood from Day 1 through Day 71, including measurements such as maximum concentration, area under the curve, time to reach maximum concentration, and half-life. Safety will be assessed by tracking any adverse events and immune responses during this period. During the study, participants will undergo physical exams, vital signs checks, ECGs, chest X-rays, and laboratory tests to ensure health status. Blood samples will be collected multiple times to analyze drug levels and antibodies. The study lasts about 71 days, with continuous monitoring for safety and drug behavior. Participants must comply with study procedures and provide informed consent before joining.
