Clinical Trial Summary

Study of Multiple Doses of PRS-060 Administered by Oral Inhalation in Subjects with Mild Asthma

Description:

PRS-060 is a drug candidate being developed for the treatment of asthma. The main purpose of this study is to investigate the safety, tolerability, and pharmacokinetics of multiple doses of PRS-060 administered by inhalation in subjects with mild asthma.
