Healthy volunteers key to heart failure Drug's first safety check

This early-stage trial tested the safety and tolerability of a new drug called SHR-6934 in 88 healthy adults. Participants received either the drug or a placebo as a single or multiple injections under the skin. The goal was not to treat any disease, but to gather important safety data and see how the body processes the drug, which is a necessary step before testing it in people with heart failure.
