This study investigates a new treatment for Pulmonary Arterial Hypertension (PAH), a condition where blood pressure in the arteries of the lungs is too high, making it harder for the heart to pump blood through the lungs. The study will test a new medication called LTP001, which comes in capsule form and is taken by mouth.
The research aims to understand if LTP001 is effective in treating people with PAH when added to their standard treatments. The study will be conducted in two parts – first testing the medication in healthy volunteers to ensure its safety, followed by testing in people who have PAH. During the study, some participants will receive LTP001 while others will receive placebo, along with their regular PAH medications.
The study will monitor how well the treatment works over 24 weeks, followed by a longer period of up to 18 months. Participants will have regular check-ups to assess their ability to walk and their overall health status. The study will look at how the treatment affects blood pressure in the lungs and how far participants can walk in a set time period.
