Welcome to the ILLUMINATE clinical study!
ILLUMINATE aims to see if an investigational treatment may be effective and well-tolerated in adults with pulmonary arterial hypertension (PAH).

Diagnosed with pulmonary arterial hypertension (PAH)? You’re not alone.
This website provides information about a clinical study, ILLUMINATE, for adults with PAH. PAH is a serious disease that causes the blood vessels in the lungs to narrow or become stiff. As a result, pressure builds up in the blood vessels which can weaken the heart over time. Currently, there is no cure for PAH, and most existing treatments do not address the underlying cause of the disease. Therefore, there is a pressing need for better treatments. This clinical research study will use an investigational drug product, the safety and efficacy of which has not been fully evaluated by Regulatory Authorities.
Clinical studies are essential to investigating potential treatments and are not possible without the people who take part. Everyone involved in this clinical study plays an important role in increasing our understanding of PAH, which may help others in the future with this condition.

Living with PAH may feel overwhelming, and you may feel that you have enough to do without committing to a clinical study. However, you may play a key role in helping to develop therapies that are being studied to help slow the progression of PAH. Every treatment that exists today is available because of study participants who actively took part in research.
