CHARLOTTE, N.C., Sept. 4, 2013 (GLOBE NEWSWIRE) -- Chelsea Therapeutics International, Ltd. (Nasdaq:CHTP) today announced that the U.S. Food and Drug Administration (FDA) has acknowledged receipt of the New Drug Application (NDA) resubmission seeking approval to market NORTHERA™ (droxidopa), an orally active synthetic precursor of norepinephrine, for the treatment of symptomatic neurogenic orthostatic hypotension (NOH). The resubmission includes additional information to resolve certain technical deficiencies previously noted by the Agency. The FDA has deemed the current resubmission a complete response to its March 28, 2012 Complete Response Letter and assigned a new Prescription Drug User Fee Act (PDUFA) goal date of February 14, 2014.
Northera was previously granted Orphan Drug Designation and received Fast Track designation from the FDA. Fast Track designation is designed to facilitate the review of products that address serious or potentially life-threatening conditions for which there is an unmet medical need.
About Symptomatic NOHNOH is a chronic neurogenic disorder resulting from deficient release of norepinephrine that predominantly affects patients with primary autonomic failure, a group of diseases which includes Parkinson's disease (PD), multiple system atrophy (MSA) and pure autonomic failure (PAF). Symptoms of NOH include: dizziness, lightheadedness, blurred vision, fatigue, poor concentration, and fainting episodes when a person assumes a standing position, often severely limiting a person's ability to perform routine daily activities that require standing or walking for both short and long periods of time. About Northera NORTHERA™ (droxidopa), the lead investigational agent in Chelsea Therapeutics' pipeline, is currently in Phase III development for the treatment of symptomatic neurogenic orthostatic hypotension (NOH) in patients with primary autonomic failure — an indication that includes a significant number of patients with Parkinson's disease, multiple system atrophy (MSA) and pure autonomic failure (PAF). Droxidopa is a synthetic catecholamine that is directly converted to norepinephrine (NE) via decarboxylation, resulting in increased levels of NE in the nervous system, both centrally and peripherally.
