Par Pharmaceutical Companies, Inc. Announces Agreement With Valeant Pharmaceuticals International To Promote Cesamet

SPRING VALLEY, N.Y., Nov. 3 /PRNewswire-FirstCall/ -- Par Pharmaceutical Companies, Inc. today announced that it has entered into an agreement with Valeant Pharmaceuticals North America to promote the antiemetic drug Cesamet(TM) (nabilone) capsules following approval by the U.S. Food and Drug Administration (FDA). Cesamet is a cannabinoid agonist for the treatment of chemotherapy-induced emesis (CIE). Valeant has received an approvable letter from the FDA for Cesamet and is awaiting final approval.

"The Par sales force is excited to add a second product to its portfolio this soon," said Scott Tarriff, president and chief executive officer of Par. "Cesamet's unique profile will benefit many of the patients suffering with CIE who have not responded to other therapies. The product also represents an ideal complement to Par's Megace(R) ES and will permit us to utilize our sales force more efficiently."

"We look forward to a very successful collaboration with Par," said Wesley P. Wheeler, president of Valeant Pharmaceuticals North America. "Cesamet is a drug that will address an important and unmet medical need for many patients. Its rapid adoption in Canada clearly demonstrates the product's utility. We expect Cesamet's U.S. introduction to benefit greatly from the efforts of Par's team of highly experienced sales professionals."

Under the terms of the agreement, Par will promote Cesamet to physicians in the U.S. Valeant will record sales of Cesamet and fund all marketing expenses associated with the product.

Valeant acquired Cesamet from Eli Lilly & Company in 2004 and currently markets the product in Canada. Cesamet now holds approximately 85 percent share of total prescriptions in the Canadian cannabinoid market.

Cesamet is intended to be marketed for use in the treatment of nausea and vomiting associated with cancer chemotherapy in patients who do not respond to conventional antiemetic treatments. Compared to similar cannabinoid treatment options, Cesamet has a longer duration of action, which allows for less frequent dosing. For patients using Cesamet, the absence of tetrahydrocannabinol (THC) detection in urine testing avoids any issues with drug testing for employment or associated stigmas.

Important Safety Information

Cesamet is contraindicated in patients whose nausea and vomiting arises from any cause other than cancer chemotherapy and in any patient known to be hypersensitive to the drug. The most frequent adverse reactions to Cesamet are vertigo, drowsiness, dry mouth, ataxia, euphoria, visual disturbance, concentration difficulties, and sleep disturbance. Patients should not drive, operate complex machinery, or engage in any hazardous activity until it is established that they are able to tolerate the drug and perform such tasks safely.
