About Questcor


Questcor Pharmaceuticals, Inc. is a biopharmaceutical company focused on the
treatment of patients with serious, difficult-to-treat autoimmune and
inflammatory disorders. Questcor also provides specialty contract
manufacturing services to the global pharmaceutical industry through its
wholly-owned subsidiary BioVectra Inc. Questcor's primary product is H.P.
Acthar^® Gel (repository corticotropin injection), an injectable drug that is
approved by the FDA for the treatment of 19 indications. Of these 19
indications, Questcor currently generates substantially all of its net sales
from the following on-label indications: the treatment of proteinuria in the
nephrotic syndrome of the idiopathic type, or NS, the treatment of acute
exacerbations of multiple sclerosis, or MS, in adults, the treatment of
infantile spasms, or IS, in infants and children under two years of age, and
the treatment of certain rheumatology related conditions, including the

has approved Acthar to "induce a diuresis or a remission of proteinuria in the
nephrotic syndrome without uremia of the idiopathic type or that due to lupus
erythematosus." Questcor is also exploring the possibility of developing
markets for other on-label indications and the possibility of pursuing FDA
