Highlight of Business Operations: Based upon the FDAs earlier confirmation that endoscopic gastric ulcers were an acceptable primary endpoint, the two pivotal trials were completed and met their primary endpoints. In both trials, patients taking VIMOVO experienced significantly (p<0.001) fewer endoscopically confirmed gastric ulcers compared to subjects receiving enteric-coated naproxen during the six-month treatment period with gastric ulcer incidence rates of 4.1 and 7.1% for VIMOVO and 23.1 and 24.3% for enteric-coated naproxen in studies 301 and 302, respectively. Data combined from both studies showed that in patients taking low dose aspirin (n=201), the incidence of gastric ulcers in the VIMOVO arm was 3.0% compared to 28.4% for those taking EC naproxen (p<0.001) and patients taking VIMOVO who were not taking low dose aspirin (n=653) experienced a 6.4% incidence of gastric ulcers compared to 22.2% among those taking EC naproxen (p<0.001). Additional analyses examined the incidence of endoscopically confirmed duodenal ulcers among patients taking VIMOVO. In study 301, patients taking VIMOVO experienced a 0.5% incidence of duodenal ulcers compared to 5.1% taking EC naproxen (p=0.003), and in study 302, patients taking VIMOVO experienced a 1.0% incidence of duodenal ulcers, compared to 5.7% incidence among patients taking EC naproxen (p=0.007). The most frequently reported adverse events among patients taking both VIMOVO and enteric coated naproxen in the pivotal trials were GI disorders, including dyspepsia, erosive esophagitis and erosive duodenitis. In addition to the Phase 3 pivotal trials, we have completed a long-term, open label safety study. In 2008 we terminated a non-pivotal smaller study in patients at high risk of gastrointestinal related events from NSAIDs which we believe is not required for approval. We also conducted additional studies at AstraZenecas expense. The NDA for VIMOVO was submitted on June 30, 2009 and was accepted for filing by FDA in August 2009. POZEN received a $10.0 million milestone payment from AstraZeneca in September 2009 for the achievement of such milestone. In October 2009, AstraZeneca submitted a Marketing Authorization Application, or MAA, for VIMOVO in the European Union, or EU, via the Decentralized Procedure, or DCP, and has filed or plans to file for approval in a number of other countries which are not covered by the DCP. On October 11 2010, we announced with AstraZeneca that VIMOVO had received positive agreement for approval in 23 countries across the EU following all 22 Concerned Member States agreeing with the assessment of the Netherlands Health Authority (MEB),
To assess whether a similar interaction occurs between clopidogrel and PA32540, which contains immediate release omeprazole, we have completed a Phase 1 drug-drug interaction study to evaluate the ex-vivo platelet aggregation effects of PA32540 plus clopidogrel dosed at the same time or dosed 10 hours apart compared to aspirin 325mg plus clopidogrel dosed together. When PA32540 and clopidogrel were dosed together, data from the study showed a mean 36.7% platelet inhibition compared to a mean 44.0% platelet inhibition when aspirin and clopidogrel were dosed together suggesting a drug-drug interaction based on the studys pre-specified primary analysis. When PA32540 and clopidogrel were dosed 10 hours apart, data from the study indicate no ex-vivo drug-drug interaction based on the studys pre-specified primary analysis. The relevance of these ex vivo platelet data on cardiovascular events is not known. Published data on a clinical interaction between PPIs and Plavix from several randomized controlled trials in cardiovascular patients have reported no clinical impact on cardiovascular outcomes [Bhatt et al (COGENT 1 2010) and ODonoghue et al (TIMI 38 2009)]. FDA assessment of these data and the implication to a future PA32540 label are not known at this time but may include a warning regarding the concomitant use of PA32540 and Plavix.
We have incurred significant losses since our inception and have not yet generated significant revenue from product sales. As of December 31, 2010, our accumulated deficit was approximately $116.9 million. We record revenue under two categories: licensing revenues and development revenues. Our licensing revenues include upfront payments upon contract signing, additional payments if and when certain milestones in the products development or commercialization are reached, and the royalty payments based on product sales. Additionally, our development revenues include the billings for the direct costs and certain personnel-related time incurred in performing additional development activities described under our collaboration agreements. Our historical operating losses have resulted principally from our research and development activities, including clinical trial activities for our product candidates and sales, general and administrative expenses. Research and development expenses include salaries and benefits for personnel involved in our research and development activities and direct development costs, which include costs relating to the formulation and manufacturing of our product candidates, costs relating to preclinical studies, including toxicology studies, and clinical trials, and costs relating to compliance with regulatory requirements applicable to the development of our product candidates. Since inception, our research and development expenses have represented approximately 70% of our total operating expenses. For the fiscal year ended December 31, 2010, our research and development expenses represented approximately 49% of our total operating expenses.
Migraine is characterized by recurring attacks of throbbing headache pain, often associated with visual, auditory or gastrointestinal disturbances. Attacks range from mild to severe and can last from 4 hours to 72 hours. In the most severe attacks, migraine sufferers are unable to pursue basic daily activities. According to the American Council for Headache Education, migraines afflict 25 million to 30 million people in the U.S. alone. As many as 6% of all men and up to 18% of all women experience a migraine headache at some time in their life. While the precise mechanism of migraine is unknown, researchers believe migraine attacks are caused by acute inflammation surrounding selected blood vessels in the head. The average migraine sufferer experiences the first attack during the early teen years, and the attacks generally continue throughout adulthood.
