U.S., April 3 -- ClinicalTrials.gov registry received information related to the study (NCT06907693) titled 'The Effects of Drug Candidate CS1 on Lung Structure and Function Utilizing FRI' on March 27.

Brief Summary: Explore the impact of drug candidate CS1 on pathological vascular remodeling of small pulmonary arteries in the disease pulmonary arterial hypertension (PAH). This sub-study for CS1-004 aims to utilize FRI, an innovative, non-invasive imaging technology to visualize how long-term use of CS1 influences structural changes in pulmonary arteries. This sub-study seeks to provide valuable insights into the potential of CS1 to transform PAH treatment in some patients enrolled in the Expanded Access Program (CS1-004).
