New Immune-Targeting injection tested in healthy people for first time
NCT ID NCT07058779
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage study tests a single dose of SSS55 injection in 26 healthy adults in China. The main goal is to check if it is safe and how the body handles it. Researchers will also look at how it affects the immune system. This is a first step before testing it in people with diseases.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
SSS55 injection (targets complement C3b, a part of the immune system)
What this could lead to
If safe, this could pave the way for future studies of SSS55 in diseases where the immune system attacks the body, like certain autoimmune conditions.
What could go wrong
This is a very early Phase 1 trial in only 26 healthy people, so it cannot tell us if SSS55 works for any disease. Side effects are unknown and may occur.
