About Celiac Sprue Celiac sprue is believed to affect as many as two million people in the United States alone, many of whom have suffered the symptoms of the disease but have not yet been diagnosed. Celiac sprue is an autoimmune disease characterized by intestinal malabsorption, abnormal small-intestinal structure, and intolerance to gluten. Even patients who are able to maintain a strict dietary regimen will suffer from this disease due to inadvertent or background exposure to gluten. Consequently, new therapies to treat this disease represent a significant, unmet medical need. About Alvine Alvine Pharmaceuticals, Inc., is a San Carlos-based biopharmaceutical company dedicated to developing and commercializing therapeutics for the treatment of celiac sprue. Alvine's lead product, ALV003, is a combination protease designed to detoxify the gluten that triggers the autoimmune response in celiac patients. In August 2007, Alvine closed a $21 million Series A financing led by Sofinnova Ventures with support from Prospect Venture Partners, InterWest Partners, Cargill Ventures and Flagship Ventures.
