Valeant Pharmaceuticals Developing Intranasal Diazepam for the At-Home Treatment of Emergency Seizures.

ALISO VIEJO, Calif. -- Valeant Pharmaceuticals International (NYSE:VRX) today announced that it is developing an intranasal form of delivery for diazepam for the treatment of seizure emergencies in children and adults, in conjunction with researchers from the University of Minnesota. Valeant currently markets Diastat[R] AcuDial[TM] (diazepam rectal gel) -- the only FDA approved at-home treatment for the acute management of increased seizure activity.

"We appreciate the commitment by Valeant to improve the treatment of epilepsy," said James Cloyd, Pharm.D., Professor and Director, Center for Orphan Drug Research at the University of Minnesota. "Although a relatively small percentage of patients with epilepsy have seizure emergencies, they result in devastating effects on a patient's health. Delays in treatment may result in refractory seizures, increased morbidity and mortality, and higher medical costs. The availability of safe, effective and easily administered drug therapies allowing patients and their caregivers to initiate treatment at the onset of a seizure emergency will improve the overall management of epilepsy."

"Valeant is excited to be collaborating with the University of Minnesota on the development of this new delivery system for diazepam," said Wesley P. Wheeler, Valeant's President of North America and Global Product Development. "A novel, nasal delivery system would provide patients and their caregivers a convenient alternative to our current Diastat AcuDial, to manage seizure emergencies outside the hospital or emergency department. Valeant is committed to supporting the development of new options for epilepsy patients through collaborations such as this with the University of Minnesota and our own development of retigabine, currently in Phase 3 clinical development."

Important Diastat AcuDial (diazepam rectal gel) Information

Diastat (diazepam rectal gel) is a gel formulation of diazepam intended for rectal administration in the management of selected, refractory, patients with epilepsy, on stable regimens of anti-epileptic drugs (AEDs), who require intermittent use of diazepam to control bouts of increased seizure activity for patients two years and older. Diastat AcuDial is supplied in a twin pack of pre-filled configurations:

-- 10 mg delivery system with a 4.4 cm tip delivers doses of 5, 7.5, and 10 mg

-- 20 mg delivery system with a 6.0 cm tip delivers doses of 10, 12.5, 15, 17.5, and 20 mg

In pivotal trials with Diastat, the most frequent adverse event reported was somnolence (23%). Less frequent adverse events reported were dizziness, headache pain, vasodilatation, diarrhea, ataxia, euphoria, incoordination, asthma, rash, abdominal pain, nervousness and rhinitis (1%-5%).
