CHARLOTTE, N.C., Aug. 14, 2013 (GLOBE NEWSWIRE) -- Chelsea Therapeutics International, Ltd. (Nasdaq:CHTP) today announced that it has submitted additional information to the U.S. Food and Drug Administration (FDA) to resolve certain technical deficiencies in the Company's resubmitted New Drug Application (NDA) for NORTHERA™ (droxidopa). Pending confirmation by the FDA, the resubmission is expected to be deemed a complete response to the March 28, 2012 Complete Response Letter (CRL) issued by the Agency. A new six month review clock, as specified under the Prescription Drug User Fee Act (PDUFA), will be set from the date of receipt.
As previously announced on July 17, 2013, Chelsea received written confirmation from the FDA that the Company's NDA resubmission was deemed to be a complete response to its CRL. The FDA later notified the Company of deficiencies in the NDA that related primarily to the formatting of certain submitted electronic datasets and statistical programs describing the methods used to generate tables and listings. The deficiencies were unrelated to study conduct, interpretability of study results, or validity of study conclusions.
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.
Droxidopa, developed by and licensed from Dainippon Sumitomo Pharma Co., Ltd. (DSP), initially received Japanese approval in 1989 for the treatment of frozen gait and dizziness on standing associated with Parkinson's Disease and for the treatment of orthostatic hypotension, syncope or dizziness on standing associated with Shy-Drager syndrome and Familial Amyloid Polyneuropathy. In 2000, Droxidopa received expanded marketing approval to include prevention of vertigo, dizziness and weakness associated with orthostatic hypotension in hemodialysis patients.
