Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a multicenter double-blind, placebo-controlled study to evaluate the safety, efficacy and pharmacokinetics of 2 doses of CXA-10 on stable background therapy in 96 subjects 18 to 80 years of age with PAH.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a multicenter double-blind, placebo-controlled study to evaluate the safety, efficacy and pharmacokinetics of 2 doses of CXA-10 on stable background therapy in 96 subjects 18 to 80 years of age with PAH.

The study will be performed in approximately 50 study centers across the United States of America and Europe. The recruitment period is anticipated to be approximately 24 months. Approximately 115 subjects will be enrolled to ensure at least 96 subjects complete the study.

Study participation for each subject will last approximately 8 months. The study will consist of a screening period (within 30 days prior to dosing), 180 days (approximately 6 months) treatment period and approximately 14 days follow-up period after the end of treatment visit.
