a study to evaluate safety and tolerability of bmn 111 administered to healthy adult volunteers

Conditions: Achondroplasia

Summary: the purpose of this study is to measure how much of the study drug gets into the blood- stream and how long it takes the body to get rid of it when given as a single dose. information about any side effects that may occur will also be collected.
