What is the PALM-PAH Study?

Thank you for your interest in the PALM-PAH Study. This is a clinical study being done to evaluate an inhaled investigational drug in adults with pulmonary arterial hypertension (PAH). This clinical study is being sponsored by Insmed Incorporated. The drug being studied is investigational and has not been approved for use in any country for any indication.

PAH is a type of high blood pressure that affects the arteries that carry blood from your heart to your lungs. These blood vessels become narrow or blocked, so the heart must work harder to pump blood through them. This extra effort can cause the heart to become weak and fail.

Researchers want to see if the study drug can improve symptoms and functioning.

Who can participate?

You may be able to participate if you meet these and other criteria:

  • Age

    Are 18 to 75 years of age

  • Diagnosis

    Have had a confirmed diagnosis of PAH for at least 3 months

  • Medicine

    Are on a stable (consistent) dose of certain medicines for PAH

What is the study treatment?

The study treatment is a dry powder that you will inhale through your mouth once a day. The study treatment is investigational and has not been approved for use in any country for any indication. During the Study Treatment Period, you will receive either the active study drug or the placebo. The placebo looks just like the study drug but contains no active ingredients. Neither you nor the study doctor will know if you are receiving the active study drug or the placebo.

After completing the 24-week Study Treatment Period, you may choose to continue into an optional Long-Term Extension Study where all participants will receive the active study drug (no placebo).
