Allergan NDA for Rosacea Topical Drug Accepted for Review
FDA has accepted for review an Allergan NDA for oxymetazoline HCl cream 1.0% for treating persistent facial erythema (redness) associated with rosacea in adults. The company expects a user fee target date in first half of 2017.
Oxymetazoline is a sympathomimetic agonist that is selective for the a1A-adrenoceptor over other a1-adrenoceptors and non-selective for the a2-adrenoceptors, Allergan says. “As such, oxymetazoline is a potent vasoconstrictor of the cutaneous microvasculature.”
The submission was based on data collected from two Phase 3 pivotal clinical trials involving a 29-day treatment duration and a one-year open label clinical trial. They enrolled male and female patients 18 years of age and older with moderate to severe persistent facial erythema associated with rosacea.
“While the pathophysiology of rosacea remains largely unknown, it is thought to be a chronic, inflammatory and vascular disorder,” the company says. It is not curable, and it usually requires long-term treatment to alleviate symptoms and delay or prevent disease progression.
