Study to Assess CMR316 in Healthy Volunteers and Patients With Idiopathic Pulmonary Fibrosis
- Registration Number
- NCT06589219
- Lead Sponsor
- Calibr, a division of Scripps Research
- Brief Summary
The purpose of this study is to assess the safety, tolerability and pharmacokinetics single and multiple inhaled doses of CMR316 in healthy volunteers and patients with Idiopathic Pulmonary Fibrosis (IPF).
- Detailed Description
This is a 3-part, single-center study; Part 1 will evaluate single ascending doses (SAD) and Part 2 will evaluate multiple ascending doses (MAD; once weekly dosing for 4 weeks) of nebulized CMR316 or placebo in healthy male and female subjects. Part 3 will assess multiple doses (once weekly dosing for 4 weeks) of nebulized CMR316 (open-label) in subjects with IPF.
