Our Patients

Our Promise to Patients: You Come First

Welcome home

You've likely had a long journey, but now you're among friends. We understand serious and rare diseases because we've specialized in them for decades and we're here to help. By working closely with people like Emily and her family (pictured above), we're able to identify and pursue new innovations that address unmet medical needs. Meanwhile, we continue to enhance our current treatments for rare diseases, including immunodeficiency and autoimmune diseases, hereditary and acquired bleeding disorders, hereditary angioedema, and Alpha 1 antitrypsin deficiency.

We are driven by our promise to save lives and improve the quality of life for our patients and their families, because living with a rare disease impacts more than just one person. We offer support programs and activities and we partner with patient advocacy organizations to improve and expand educational and outreach efforts. We also work with government authorities to ensure patients have access to the medicines they need to live life to the fullest.

Our Alpha 1 Antitrypsin treats Alpha 1 Antitrypsin Deficiency (AATD) in patients with AATD-related emphysema.

Find a Clinical Trial

A clinical trial is a research study that is done to find out if medical treatments can improve people’s health. A medical treatment can be a drug, medical device, medical procedure, or a change in a person’s behavior such as diet or exercise. People who take part in clinical trials are volunteers. They are also called “participants."
