FDA Accepts CSL Behring BLA for Hereditary Angioedema Attacks
FDA has accepted for review a CSL Behring BLA for its low-volume subcutaneous CSL830 (C1-esterase inhibitor (C1-INH) human) replacement therapy for preventing hereditary angioedema (HAE) attacks. The rare genetic disorder is caused by a deficiency of C1-INH, one of the proteins that work with the immune system to control inflammation, according to the company. Symptoms of HAE include episodes of swelling in the face, abdomen, larynx and extremities and can be fatal if untreated. CSL830 works by replacing the missing or malfunctioning C1-INH protein in patients with a C1-INH deficiency and thereby preventing HAE attacks, it says.
