Summary

This trial tests a new drug to see if it's safe, effective, and how it works in people for the first time.

Who is the study for?
Adults aged 18-75 with Myasthenia Gravis (MG), experiencing muscle weakness, who have not had certain treatments or surgeries recently. They must have specific MG symptom scores, stable medication doses for 3 months, and agree to use effective birth control. Excludes those with mild or very severe MG, recent strokes, other immune disorders requiring immunosuppressants, significant cardiovascular disease, or a history of certain cancers.
What is being tested?
The trial is testing CNP-106's safety and effectiveness in treating Myasthenia Gravis compared to a placebo. It's the first time this drug is being given to humans (First-in-Human) and will involve increasing doses to see how patients respond (multiple ascending doses).
What are the potential side effects?
Potential side effects are not detailed but may include reactions typical of new medications such as allergic responses, issues at the injection site, general discomfort or changes in blood tests that monitor organ function.
