About H.P. Acthar Gel (repository corticotropin injection)
H.P. Acthar Gel (repository corticotropin injection), is an injectable drug approved by the U.S. Food and Drug Administration (FDA) for the treatment of 19 indications. Of these 19 indications, the product 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 (NS), the treatment of acute exacerbations of multiple sclerosis (MS) in adults, the treatment of infantile spasms (IS) in infants and children under two years of age, and the treatment of certain rheumatology related conditions, including the treatment of the rare and closely related neuromuscular disorders dermatomyositis and polymyositis. The company is also exploring the possibility of developing other on-label indications and the possibility of pursuing FDA approval of additional indications not currently on the Acthar label where there is high unmet medical need.
