Phase 3 Clinical Trial Next Generation Dihydroergotamine With Advanced Inhaler Delivery Offer Migrainuers More Choice
MAP Pharmaceuticals Embarks On Phase 3 Clinical Trial in Patients With Migraine Disease
WASHINGTON, DC; August 14th, 2008—Football season is here again, and with it so are the weekend rituals followed by those Monday morning quarterbacking sessions with our co-workers and friends.
This made us realize while advocating for Migraine disease we have had the opportunity to meet some of the NFL’s greatest players! Sometimes this opportunity happened when Michael John has as a Migraine Art Awareness Exhibit which we had the pleasure to meet NLF All-Pro Washington Redskins Darrell Green and John Riggins, both wearing their Super Bowl rings to boot!
But it is another NFL hero we met that comes to mind when Michael John saw several medical posters back in Boston earlier this summer at the American Headache Society 50th Annual Scientific Meeting. Many years ago Michael John spent some time talking with the Denver Bronco’s All Star player Terrell Davis right after his MVP (most valuable player) award for his performance in Super Bowl XXXII. Michael John was attending the AHS medical meeting in San Francisco back then and met Terrell at an AHS evening event. The two talked about Migraines, Man-to-Man Coverage, and MAGNUM. He has just signed a different kind of contract, one as a health advocate for Migraine awareness for a drug company called Novartis Pharmaceuticals Corporation, the makers of the drug that allowed him to get back in the game, the Super Bowl game that is—D.H.E. 45 also known as Dihydroergotamine.
“Davis shrugged off the onset of a migraine headache to accumulate 157 yards on 30 carries as the Broncos outrushed the Packers, 179-95, only the second time the AFC has outrushed the NFC in the last 14 years.”

Now for those of you who follow your sports as well as love sports trivia, and who couldn’t in the shadow of the 24/7 coverage of the China Olympics these days? Well, have to tell you hundreds of sports writers just plain got part of the story of the Super Bowl XXXII’s MVP wrong! The common sports page report of how “Denver Bronco’s Terrell Davis played with a horrible Migraine ‘headache’ to overcome and became the first player in Super Bowl history ever to score 3 rushing touchdowns.” Nope. Did not happen that way. We should know, MAGNUM fielded dozens of calls during Super Bowl Sunday, days later even talking to the Denver Bronco’s team doctor to get the facts straight.
In fact it was not Imitrex® that broke Terrell’s monster Migraine as reported by most sports pages back then, rather it was a Migraine abortive medication called D.H.E. 45, a Dihydroergotamine ergot family drug which Terrell wisely had administered via injection during the prodrome phase of his Migraine. So he was never in any pain because the D.H.E. 45 successfully aborted his Migraine about midway into the third quarter of the famous football game, after sitting out the second quarter of play and the extended Super Bowl halftime that is. But the side effects of this older Dihydroergotamine such as numbness to the extremities (his hands and feet) would explain Terrell’s sluggish start and fumble in the beginning of the second half. Anybody who has used D.H.E. 45 can tell you about their cold hands and feet with numbness and tingling, which can be annoying--but luck for most of us we are not catching any footballs.
But boy would have Terrell Davis loved to have had this new Migraine treatment about to go into phase three FDA clinical trials from MAP Pharmaceuticals. They have created a new improved Dihydroergotamine and much better delivery system for the patient to take during their prodrome. Remember sports fans, early intervention when it comes to our Migraines and our abortive meds.
So this MAP Pharmaceuticals company presented a poster summarizing the receptor pharmacology data entitled "Improved Dihydroergotamine (DHE) Pharmacology Following Orally-Inhaled Delivery." In addition to this study, the Company presented five posters relating to the MAP0004 program, including:
-- Newer Acute Migraine Specific Drugs May Provide Improved Sustained Relief and Freedom Over 24 and 48 Hours Post Dosing
-- Chronic Inhalation Toxicological Assessment of Dihydroergotamine in Dogs
-- Assessment of QTc Effect of DHE When Delivered Via the Lung by the Tempo Inhaler
-- MAP0004, an Orally Inhaled Formulation of DHE, Delivers Faster and More Consistent Blood Levels of the Drug Compared to Traditional Oral, Subcutaneous, Intramuscular, and Intranasal Formulations of DHE
-- Systemic Pharmacokinetics of DHE When Delivered Via the Lung to Asthmatics by the Tempo Inhaler
Terrell Davis would have appreciated a new improved dihydroergotamine with improved performance to defeat his Migraines. So let’s see the data MAP Pharmaceuticals, Inc. presented from an in-vitro study evaluating receptor pharmacology of a new drug that the industry is calling MAP0004, orally inhaled dihydroergotamine (DHE) for the potential treatment of Migraine, and compared to intravenous (IV) DHE.
In the receptor pharmacology study, MAP0004 stimulated receptors that relieve Migraine at levels comparable to intravenous injection (IV) DHE, but did not activate receptors associated with side effects frequently seen with IV DHE. In addition, MAP0004 did not affect receptors that have a role in regulating pulmonary (lungs) function.
According to MAP Pharmaceuticals Chief Scientific Officer; "The selective binding of MAP0004 at receptors associated with Migraine rather than those associated with side effects offers a mechanistic hypothesis for the favorable safety and efficacy profile of MAP0004 compared to IV DHE that we have observed in our initial clinical studies," Thomas A. Armer, Ph.D., Chief Scientific Officer of MAP Pharmaceuticals went on to say: "The absence of negative effects of MAP0004 on pulmonary function in asthmatic subjects observed in a Phase 2 study is also important because migraine and asthma are frequently co-morbid conditions."
MAP0004 is designed to be self-administered by patients at home via MAP Pharmaceuticals' proprietary Tempo(R) inhaler. In Phase 2 studies with Migraneurs and with asthmatics, treatment with MAP0004 was well-tolerated, with no serious adverse events reported. Drug-induced nausea was very low and Migraine-associated nausea also decreased with treatment.
About MAP0004
MAP0004 is a proprietary orally inhaled version of dihydroergotamine, or DHE, intended to treat migraine. In the Company's Phase 2 efficacy study, MAP0004 provided pain relief as early as within ten minutes of dosing, and this relief was sustained through at least 24 hours. The study also demonstrated efficacy trends in treating nausea, photophobia and phonophobia. Based on these results, as well as independent research who conclude that patients prefer migraine therapies providing fast onset, pain relief, sustained pain relief and safety, the Company believes that MAP0004 has the potential to be a first-line therapy for migraine patients. Historically, estimated onset of significant pain relief with oral triptans, the class of drugs most often prescribed for treating migraine, occurs between 45 and 90 minutes after dosing. In 2007, triptans generated sales of approximately $2.2 billion in the United States, according to data published by IMS Health.
MAP0004 is designed to be an easy to use, non-invasive, at-home therapy that patients self-administer using the Company's proprietary hand-held Tempo inhaler. DHE is currently available as an intravenous therapy which has been used in clinical settings for over 50 years for the safe and effective treatment of migraine, but requires healthcare intervention for administration. In the Company's Phase 2 clinical efficacy study, MAP0004 was shown to retain the rapid onset and long-lasting effectiveness of intravenous DHE while avoiding the nausea that intravenous administration can cause.
About Tempo Migraine
MAP Pharmaceuticals is developing a series of inhaled respiratory and systemic drug products delivered with the Tempo(TM) Inhaler platform. The first of these products is a systemic migraine treatment that is designed to provide faster and more consistent relief than current therapeutics. In early human studies, Tempo Migraine delivered therapeutic blood levels within minutes of inhalation, similar to those seen after intravenous injection. This performance will potentially allow Tempo Migraine to mimic both the therapeutic blood levels and efficacy of injectable therapy - offering fast relief without injections. By providing rapid onset with a novel formulation of a proven compound (dihydroergotamine mesylate), MAP Pharmaceuticals seeks to meet the treatment needs of the large, underserved population of migraine sufferers with Tempo Migraine.
Last month MAP Pharmaceuticals issued a press release about the fact that it has initiated its Phase 3 clinical program to evaluate MAP0004 as a potential treatment for migraine.MAP0004 is orally inhaled and self-administered at home using MAP Pharmaceuticals' proprietary Tempo(R) inhaler. In the company's prior Phase 2 efficacy study, MAP0004 provided pain relief in as fast as 10minutes, with relief sustained through at least 24 hours. The study also demonstrated efficacy trends in treating nausea, photophobia and phonophobia, the other key measurements in treating migraine.
What impressed MAGNUM was the improved rapid effect of the drug to abort a Migraine attract and looks to offer sustained relief to 24 and 48 hours. Something we hope to see this final phase of the FDA clinical trial bare out.
This randomized, double-blind, placebo-controlled Phase 3 trial is designed to evaluate the efficacy and safety of MAP0004 in treating acute Migraine. The primary efficacy endpoints will be pain relief, and freedom from nausea, photophobia and phonophobia as measured at two hours after dosing. MAP will also evaluate earliest onset of pain relief and sustained relief to 24 and 48 hours. The multi-center efficacy trial will include approximately 850 patients, who will also be followed for 12 months in an open-label study to confirm long-term safety.
"We believe that MAP0004 has the potential to be a first-line therapy for Migraine patients," said Timothy S. Nelson, president and chief executive officer of MAP Pharmaceuticals. "Based on our initial clinical studies, we believe that MAP0004 offers an alternative to triptans that may provide patients with the benefits of rapid onset and long-lasting pain relief, in an easy-to-use, non-invasive, at-home therapy. In our Phase 2 trials, MAP0004 was well tolerated with no effect on pulmonary function, including in asthmatic subjects."
MAP Pharmaceuticals is initiating the first Phase 3 trial of its MAP0004 product candidate pursuant to a Special Protocol Assessment (SPA) with the U.S. Food and Drug Administration. The SPA is intended to provide assurance that if pre-specified trial results are achieved, they may serve as the primary basis for an efficacy claim in support of a new drug application. In general, these assessments are considered binding on the FDA as well as the sponsor unless public health concerns unrecognized at the time the SPA is entered into become evident or other new scientific concerns regarding product safety or efficacy arise.
MAGNUM points out that there are Migraineurs who do not respond well to triptans and others who cannot use them, an improved dihydroergotamine mesylate administered with an improved oral delivery system in the Tempo® will be welcome in the Migraine community with open arms. So we will be watching, and maybe even some new NFL players will too!
Regarding some of the benefits of the developmental medicine MAP0004 MAGNUM was talking about, here is a group of improvements the manufacture based on Phase 1 and 2 clinical studies, MAP Pharmaceuticals believes that MAP0004 may provide patients with the following benefits (when compared to existing therapies):
MAP0004 May Provide Patients With The Following Benefits
Rapid onset: Treatment with 0.5 mg of MAP0004 provided pain relief in as fast as 10 minutes of dosing.
Long-lasting: MAP0004 provided long-lasting pain relief with low incidence of recurrence. Phase 2 studies support pain relief through at least 24 hours.
Broadly efficacious: Based on historical DHE use, MAP0004 may provide a higher response rate and has the potential to treat patients who have not previously responded to other therapies.
Convenient and consistent delivery: MAP0004 is non-injectable and easy to use, which results in increased patient comfort and compliance. Phase 2 studies were performed in the home, without clinical supervision and with minimal training.
Low incidence of side effects: Treatment with MAP0004 was well-tolerated, with no serious adverse events reported.
