MDRNA, Inc. Announces Tentative FDA Approval of Generic Calcitonin-Salmon Nasal Spray for Osteoporosis
BOTHELL, WA, Dec 15, 2008 (MARKET WIRE via COMTEX News Network) -- MDRNA, Inc. (NASDAQ: MRNA) announced today that the U.S. Food and Drug Administration (FDA) has granted tentative approval of MDRNA's Abbreviated New Drug Application (ANDA) for generic calcitonin-salmon nasal spray for the treatment of osteoporosis. Full FDA approval would follow the completion of Apotex's 180-day exclusivity period, or June 2009.

MDRNA's generic calcitonin-salmon nasal spray, a legacy product developed by MDRNA in the early 2000s, is the generic equivalent of Miacalcin(R) marketed by Novartis Pharmaceuticals Corporation. U.S. sales of Miacalcin(R) were approximately $147 million in 2007.

On December 23, 2003, FDA accepted for filing MDRNA's 505(j) paragraph 4 ANDA for the product. In October 2004, MDRNA and Par Pharmaceutical Companies, Inc. entered into an exclusive license and supply agreement for U.S. distribution and marketing of the product. Under terms of the agreement, MDRNA is responsible for obtaining regulatory approval and manufacturing, and will receive product transfer payments for manufactured product and profit sharing following commercialization.

"We are pleased that our generic calcitonin-salmon nasal spray has received tentative FDA approval and we look forward to full FDA approval in mid 2009," stated J. Michael French, President and CEO of MDRNA. "Although we are now a company solely focused in the research and development of RNAi-based therapeutics, we are pleased to see the successful culmination of years of hard work on the part of many current and former members of the MDRNA/Nastech team. I want to personally thank them all for their efforts in bringing this product forward. We are assessing our short- and long-term options to understand how this tentative approval can be leveraged toward the continued advancement of our RNAi drug discovery engine."

About Calcitonin

MDRNA's calcitonin-salmon nasal spray is a generic version of Miacalcin(R), an FDA approved calcitonin-salmon nasal spray marketed by Novartis for the treatment of osteoporosis. Calcitonin is a natural peptide hormone produced by the thyroid gland that acts primarily on bone. Calcitonin-salmon appears to have actions essentially identical to calcitonins of mammalian origin, but its potency is greater due to a longer duration of action. Novartis' Miacalcin(R) has been shown to increase spinal bone mass in post-menopausal women with established osteoporosis.
