Summary
Brief summary
This study is to assess the safety, tolerability, pharmacokinetics (the amount of drug in the blood), pharmacodynamics (how the drug effects the body) and immunogenicity (how the drug effects the immune system) of a single dose of an investigational drug called ALPN-303. Multiple dose levels will be tested.
