MEDA Announces Dymista Approved by the FDA: The U.S. Food and Drug Administration (FDA) has approved Dymista, a new patented product for treatment of seasonal allergic rhinitis (SAR). In several clinical studies, MP29-02 (tentatively called Dymista), a novel intranasal formulation of azelastine hydrochloride (above left structure) and fluticasone propionate (right structure).
The first study demonstrated that continuous treatment with MP29-02 for 1 year was well tolerated in patients with chronic allergic or non-allergic rhinitis, only 2.7% of patients treated with MP29-02 and 2.9% of patients treated with fluticasone propionate discontinued the study due to an adverse event. MP29-02 also provided sustained efficacy over the one-year study period. MP29-02-treated patients experienced consistently greater relief from their nasal symptoms than fluticasone treated patients over the course of the study. Statistically significant (P<.05) differences favoring MP29-02 over fluticasone were observed at months 1 through 7 and at months 9 and 11.
The second and third studies in patients with seasonal allergic rhinitis (SAR) provided evidence that MP29-02 demonstrated significantly more effective relief of nasal symptoms (P<.05 vs. azelastine, fluticasone, and placebo) and significantly greater ocular benefits compared to placebo (P<.05) over a 2-week study period. The new data was the subject of platform presentations on Sunday, March 4, 2012 at the annual meeting of the American Academy of Allergy Asthma and Immunology (AAAAI) in Orlando, Florida. MP29-02 is currently under review by the U.S. Food and Drug Administration (FDA) for the treatment of SAR.
