CONDITIONS WE TREAT
Understanding Rare Diseases, Every Day
We’re dedicated to delivering life-changing medicines for those with rare and devastating diseases. Our innovation begins when we understand the challenges that people living with these rare diseases and their families face every day.
Atypical Hemolytic Uremic Syndrome
aHUS is an ultra-rare genetic, chronic, potentially life-threatening disease that can progressively damage vital organs, such as the kidneys.1LEARN MORE
Generalized Myasthenia Gravis
gMG is a debilitating, chronic and progressive autoimmune neuromuscular disease that can occur at any age but most commonly begins for women before the age of 40 and men after the age of 60.2-5LEARN MORE
HPP is a genetic, chronic, progressive, and life-threatening metabolic disease in which patients experience devastating effects on multiple systems of the body, leading to debilitating or life-threatening complications.6LEARN MORE
Lysosomal Acid Lipase Deﬁciency
LAL-D is a genetic, chronic and progressive ultra-rare metabolic disease in which uncontrolled accumulation of cholesteryl esters and triglycerides may lead to multi-organ damage in infant, pediatric, and adult patients and premature death in infants.7LEARN MORE
Neuromyelitis Optica Spectrum Disorder
NMOSD is a rare and devastating complement-mediated disorder of the central nervous system (CNS) characterized by relapses where each individual attack results in cumulative disability.8-12LEARN MORE
Paroxysmal Nocturnal Hemoglobinuria
PNH is a chronic, progressive, debilitating, and potentially life-threatening ultra-rare blood disorder characterized by complement-mediated hemolysis (destruction of red blood cells).13,14LEARN MORE
