MOUNTAIN VIEW, Calif., June 23, 2011 /PRNewswire/ -- MAP Pharmaceuticals, Inc. (Nasdaq: MAPP) today announced that LEVADEX® orally inhaled migraine drug will be featured in four poster presentations, including one late-breaker presentation, at the 15th Congress of the International Headache Society (IHC) in Berlin, Germany on June 23-26, 2011. LEVADEX is an investigational drug for migraine and the Company has submitted a New Drug Application to the U.S. Food and Drug Administration for the potential acute treatment of migraine in adults.
The posters will be presented on Friday, June 24, 4:00-5:00 p.m. CET during Poster Shift 1:
A Long-Term Open-Label Study Assessing the Safety and Tolerability of LEVADEX Orally Inhaled Dihydroergotamine in Adult Migraineurs: In this study, LEVADEX was well-tolerated for the acute treatment of migraine, and did not appear to be associated with any unique safety risk from the inhaled mode of administration.
Abstract #: Late breaking 648
A Thorough QT Study Comparing Supratherapeutic Dose of Orally Inhaled DHE, Moxifloxacin, and Placebo on the QT Interval in Healthy Volunteers: A supratherapeutic dose of orally inhaled DHE, three times the intended clinical LEVADEX dose, did not prolong QTc intervals.
Abstract #: A-345-0001-00565
A Drug Interaction Study Assessing the Effects of CYP3A4 Inhibition on the Pharmacokinetics of LEVADEX (MAP0004, Orally Inhaled DHE) in Healthy Volunteers: Co-administration of LEVADEX with a potent CYP3A4 inhibitor showed no effects on the plasma levels of DHE or its elimination. Therefore, the potential for potent CYP3A4 inhibitors to enhance or prolong the pharmacological effects of orally inhaled DHE appears to be minimal.
Abstract #: A-345-0001-00611
Assessment of the Consistency of Pharmacokinetic Parameters of LEVADEX (MAP0004, Orally Inhaled DHE) in Healthy Volunteers — Results from 3 Clinical Studies: Pooled analyses assessing the clinical pharmacokinetics of LEVADEX and its primary metabolite across three recent clinical studies show consistent pharmacokinetic results and rapid absorption via the pulmonary route of administration.
Abstract #: A-345-0001-00616
Poster presentations will be available on the Publications section of MAP Pharmaceuticals' website at http://www.mappharma.com by the conclusion of the Congress.
LEVADEX is an investigational drug for migraine. The Company has submitted a New Drug Application to the U.S. Food and Drug Administration for the potential acute treatment of migraine in adults. In the clinical trial, patients administered LEVADEX themselves using the proprietary TEMPO® inhaler. LEVADEX contains a novel formulation of dihydroergotamine (DHE). LEVADEX was evaluated in the efficacy portion of FREEDOM-301, MAP Pharmaceuticals' Phase 3 pivotal trial, which included 395 patients in the LEVADEX arm and 397 patients in the placebo arm. In the Phase 3 trial, patients taking LEVADEX had statistically significant improvement at two hours compared to patients on placebo for all four co-primary endpoints:
- Pain relief: 58.7 percent of patients who received LEVADEX compared with 34.5 percent for placebo (p<0.0001);
- Phonophobia free: 52.9 percent of patients who received LEVADEX compared with 33.8 percent for placebo (p<0.0001);
- Photophobia free: 46.6 percent of patients who received LEVADEX compared with 27.2 percent for placebo (p<0.0001); and
- Nausea free: 67.1 percent of patients who received LEVADEX compared with 58.7 percent for placebo (p=0.02).
The most common adverse event reported was medication aftertaste at six percent versus two percent for placebo. The next most common adverse event was nausea at five percent compared with two percent for placebo. There were no decreases in lung function, as measured by spirometry, between the active and placebo groups.
Common symptoms of migraine include recurrent headaches, nausea, vomiting, photophobia (sensitivity to light) and phonophobia (sensitivity to sound). According to the National Headache Foundation, most migraines last between four and 24 hours, but some last as long as three days. On average, migraine sufferers experience three migraine attacks monthly, although 25 percent of them experience one or more attacks weekly. The economic burden of migraine remains substantial despite existing treatments, with the direct and indirect costs of migraine in the United States estimated at over $20 billion annually.
