The purpose of this research study is to continue to test how well the Endospan NEXUSTM Aortic Arch Stent Graft System performs in the treatment of a diseased aortic arch. The aortic arch is the top part of the main large vessel that carries blood away from the heart. A stent graft is a self-expanding frame that is covered with a material intended to seal the vessel walls.
The NEXUS Aortic Arch Stent Graft System is delivered to the diseased area of your aorta by traveling through your vascular system using fluoroscopic guidance (x-ray pictures), starting with a small incision or needle puncture near your groin (inner thigh). The NEXUS Aortic Arch Stent Graft System is being studied and is not approved by the FDA which means it is investigational in this study. The NEXUS Aortic Arch Stent Graft System has CE Mark which means it is approved for use in Europe. The NEXUS Aortic Arch Stent Graft System is only available through the clinical study in the United States.

This is a randomized, double-blind, placebo-controlled clinical study to evaluate the safety and efficacy of 2 doses of AP01 versus placebo on top of standard of care in subjects with Progressive Pulmonary Fibrosis (PPF) over 52 weeks. Subjects will participate in the study for up to 58 weeks, inclusive of a Screening Period of up to 4 weeks, a 52-week Treatment Period, and a 2-week Follow-up Period that includes a Follow-up telephone call (TC) 2 weeks post final dose. Up to 300 eligible subjects will be randomized in a 2:1:2 ratio to 1 of 3 treatment arms: AP01 100 mg twice daily (BID), AP01 50 mg BID, or placebo BID (8 mL; two 4 mL blow-fill-seal [BFS] ampoules BID).
