Endo Pharmaceuticals and Vernalis plc Announce the Filing of the Supplemental NDA for Frova(R) for Short-Term Prevention of Menstrual Migraine

CHADDS FORD, Pa., and WINNERSH, England, July 19 (HSMN NewsFeed) -- Endo Pharmaceuticals Holdings Inc. (Nasdaq: ENDP ) and Vernalis plc (LSE: VER, Nasdaq: VNLS) today announced that Endo has submitted to the U.S. Food and Drug Administration (FDA) a supplemental New Drug Application (sNDA) for FrovaŽ (frovatriptan succinate) 2.5 mg tablets for the short-term (six days per month) prevention of menstrual migraine (MM). This submission contains data from previously reported pivotal Phase III studies that met their primary efficacy endpoints of reduction in incidence in MM.

If the sNDA is approved by the FDA, FrovaŽ will be the only triptan indicated in the U.S. for the prevention of MM. Currently, FrovaŽ is FDA-approved for the acute treatment of migraine attacks with or without aura in adults where a clear diagnosis of migraine has been established.

Approximately 21 million American women suffer from migraines. Of these female migraineurs, approximately 60 percent, or 12 million women, are estimated to suffer from menstrual migraines, a condition which can have a serious and debilitating impact. Compared to non-menstrual migraines, menstrual migraines can be more severe and are reported to be longer in duration, often lasting up to three days.

"Doctors and patients need to understand that menstrual migraine differs from other kinds of migraines. These differences need to be taken into consideration in order for the condition to be treated appropriately," said Stephen Silberstein, M.D., professor of neurology at the Jefferson Medical College of Thomas Jefferson University, director of the Jefferson Headache Center and lead investigator of the initial efficacy study of FrovaŽ for the short-term prevention of menstrual migraine. "The predictable nature of menstrual migraine supports the future use of preventative therapy for this disabling condition."

"menstrual migraines disrupt the lives of millions of women, but currently no triptan is approved to prevent them," said Peter A. Lankau, president and chief executive officer of Endo, which markets FrovaŽ in the U.S. "If approved, FrovaŽ would provide a novel treatment approach to address this unmet medical need. We are pleased to be submitting this sNDA for FrovaŽ to the FDA and will work closely with the Agency throughout the review process."

Simon Sturge, chief executive officer of Vernalis, stated "The data confirm the potential of FrovaŽ for the prevention of menstrual migraine. Short-term prevention could be a major benefit for women who do not respond well to acute treatment. We continue to be impressed by the therapeutic potential of FrovaŽ."

The sNDA for FrovaŽ is supported by data from four studies, including two Phase III studies examining the efficacy and safety of once- and twice-daily dose regimens of FrovaŽ in the short-term prevention of MM, a pharmacokinetics and tolerability study of once and twice-daily dosing of FrovaŽ, and a 12-month open-label safety study evaluating a six-day dosing regimen of FrovaŽ in 525 women.

Important Information about FrovaŽ

FrovaŽ was approved by the FDA on November 8, 2001 for the acute treatment of migraine attacks with or without aura (subjective symptoms at the onset of a migraine headache) in adults. FrovaŽ is generally well tolerated, with a side-effect profile that is typical of the triptan class of drugs. FrovaŽ is indicated for the acute treatment of migraine attacks with or without aura in adults where a clear diagnosis of migraine has been established. FrovaŽ is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine. The safety and effectiveness of FrovaŽ have not been established for cluster headache, which is present in an older, predominantly male population.

FrovaŽ should not be given to patients with cerebrovascular syndromes, peripheral vascular disease, uncontrolled hypertension, ischemic heart disease, or to patients who have symptoms or findings consistent with ischemic heart disease, coronary artery vasospasm, including Prinzmetal's variant angina or other significant underlying cardiovascular disease. FrovaŽ should not be given to patients within whom unrecognized coronary artery disease is predicted by the presence of risk factors without a prior cardiovascular evaluation.

The most common adverse events (>/=4%) include dizziness, fatigue, paresthesia, flushing, and headache.

The FDA-approved dosing for FrovaŽ is one 2.5 mg tablet up to three times within a 24-hour period. FrovaŽ is not currently approved by the FDA for any indications other than for the treatment of acute migraine headaches, and its safety and efficacy in other indications have not been established.

FrovaŽ is licensed for this indication in the US. For other countries, check local prescribing information. Not necessarily licensed for this indication outside the US. Not for release in the UK.

About menstrual migraine

menstrual migraine (MM) can have a serious impact on women's lives because they last longer than non-menstrual migraines, tend to be associated with severe pain and come back more often. Patients with MM may suffer from migraines at any time, although their migraine is frequently linked to their menstrual cycle. Over 60 percent of migraines in women are associated with menstruation.
