Business Wire
Winston Pharmaceuticals, Inc. (“Winston”), a specialty
pharmaceutical company focused on developing and commercializing
novel pain management therapies, announced the results of its Phase
II study on its patented Dolorac® Nasal Solution (doxepin 0.4%) for
prophylaxis of chronic migraine (“CM”) at the Lazard Capital
Markets 7th Annual Healthcare Conference in New York.
In the 210 patient Phase II double-blind, vehicle-controlled,
multi-center study on patients with ≥180 headache days per year,
twice-daily administration of Dolorac was significantly more
effective than control in improving the primary efficacy variables
of Headache Duration and Patient Global Satisfaction (P=0.0013 and
P=0.0002, respectively). Winston expects to initiate two Phase III
pivotal studies, each enrolling 300-350 patients with CM in Q2
2011.
Joel E. Bernstein, M.D., Winston’s President and Chief Executive
Officer, commented, “There are as many as 12 million patients with
CM in the U.S. and a similar number in the European Union. Taking
into account the chronicity of the condition and the large number
of CM sufferers, this is a very large market.”
Dr. Bernstein added, “The only product approved for prophylaxis
of CM is Botox®, and this treatment requires 31 injections into the
head and neck every 12 weeks. Furthermore, Botox treatment is
accompanied by a number of not infrequent serious side effects, and
will cost the patient in excess of $20,000 per year. The over 500
patients who have utilized Dolorac nasal solution have experienced
no systemic side effects, and Dolorac requires just one spray in
each nostril twice daily. Consequently, Dolorac has significant
safety, convenience and pharmaco-economic advantages over Botox
injections.”
