Our Patients

Our promise to patients: You come first

We are here so that you don’t have to suffer in silence

At CSL Behring, patients always come first. We understand serious and rare diseases because we've specialized in them for decades. By working closely with patients and their, 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, and hereditary angioedema.  

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. Through our local partners, we collaborate 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.
