Repligen Receives Orphan Drug Designation from the FDA for RG1068 for MRI Imaging of the Pancreas

WALTHAM, Mass., Nov. 21 (HSMN NewsFeed) -- Repligen Corporation (Nasdaq: RGEN ) announced today that the Office of Orphan Products Development of the U.S. Food and Drug Administration (FDA) granted orphan drug designation to RG1068, synthetic human secretin, for use with magnetic resonance imaging (MRI) of the pancreas. Orphan drug designation qualifies Repligen for seven years of exclusive marketing rights in the United States if the company is first to receive marketing approval for RG1068 for MRI imaging of the pancreas. The designation also provides for benefit from certain tax credits and waives the company's obligation to pay the FDA application user fees for this product as required by the Prescription Drug User Fee Act. Repligen is currently conducting a multi-center, Phase 2/3 clinical trial of RG1068 as an agent to improve the detection of structural abnormalities of the pancreatic ducts during MRI imaging of the pancreas as well as a Phase 1 investigator study to assess the utility of secretin for functional imaging of the pancreas. The U.S. Orphan Drug Act provides incentives for companies developing and marketing therapies for rare diseases, defined as those affecting fewer than 200,000 Americans.

"We are very pleased to receive Orphan Drug Designation from the FDA," stated Walter C. Herlihy, President and Chief Executive Officer of Repligen. "We believe there may be more than 100,000 pancreatic MRI's in the U.S. each year that could benefit from the use of secretin."

Secretin is a natural gastrointestinal hormone involved in the process of digestion. Secretin has been used for many years by gastroenterologists in combination with endoscopy, an invasive procedure to evaluate and treat diseases of the pancreas and gallbladder. There are risks associated with the use of endoscopy, which have generated interest in the development of safer non-invasive tests to diagnose gastrointestinal disorders. The use of a non- invasive procedure such as MRI to improve the detection and delineation of normal and abnormal structures of the pancreas and to quantify pancreatic fluid production following secretin administration harnesses the natural biologic properties of the hormone and may improve the diagnostic quality of the MRI image. The use of MRI is attractive for patient care as it can obviate the need for more risky invasive procedures.
