Healthcare Industry News: Neuropathic Pain
News Release - October 17, 2006
Endo Pharmaceuticals Comments on Lidoderm(R)CHADDS FORD, Pa., Oct. 17 (HSMN NewsFeed) -- Endo Pharmaceuticals Holdings Inc. (Nasdaq: ENDP ) announced today that its wholly owned subsidiary, Endo Pharmaceuticals Inc., has learned that the Division of Bioequivalence, Office of Generic Drugs, Center for Drug Evaluation and Research ("OGD") has issued, in response to an inquiry, bioequivalence recommendations regarding Endo's patent-protected product, LidodermŽ (lidocaine topical patch 5%).
The company has learned that OGD has recommended a bioequivalence study characterizing the pharmacokinetic profile of lidocaine as well as a skin irritation/sensitization study of any lidocaine-containing patch formulation. This deviates from Endo's understanding of the applicable regulations and of OGD's past practices, which, for a topically acting product, have generally required demonstration of bioequivalence through a comparative clinical efficacy study. It should be noted that Lidoderm is a topically acting product that works locally at the site of application rather than through systemic absorption of the active ingredient. Accordingly, Endo believes that clinical studies consistent with those required for other topical products are more appropriate in proving bioequivalence to Lidoderm. Endo has already expressed this view to OGD, and these discussions are ongoing.
Importantly, Lidoderm is covered by five Orange Book-listed patents, the last of which is set to expire in 2015. These patents form the basis of what the company believes is a strong intellectual property estate around Lidoderm and cover not only the product's method of use in Neuropathic Pain, including post-herpetic neuralgia pain, but also its formulation. Endo intends to vigorously assert these patents against any challenge to Lidoderm.

Lidoderm (lidocaine patch 5%) is a topical analgesic patch approved by the U.S. Food and Drug Administration (FDA) in 1999 to treat the pain associated with post-herpetic neuralgia (PHN), a chronic condition resulting from nerve damage caused by shingles. Lidoderm produces an analgesic effect by the penetration of lidocaine. Lidoderm should only be applied to intact skin. Lidoderm is contraindicated in patients with a history of sensitivity to local anesthetics (amide type) or any product component. The potential exists for a small child or a pet to suffer serious adverse effects from chewing or ingesting a new or used Lidoderm patch, although the risk with this formulation has not been evaluated. It is important for patients to store and dispose of Lidoderm out of the reach of children and pets.
Excessive dosing of Lidoderm could result in increased absorption of lidocaine and high blood concentrations leading to serious adverse effects. Lidoderm should be used with caution in patients with severe hepatic disease, pregnant or nursing mothers, or those receiving Class 1 antiarrhythmic drugs (such as tocainide and mexiletine) because of the potential for serious adverse effects. Avoid contact of Lidoderm with the eye. If eye contact occurs, immediately wash out the eye with water or saline and protect the eye until sensation returns. During or immediately after Lidoderm treatment, application-site reactions may occur. The most commonly reported post- marketing adverse events are: application-site erythema, burning sensation, dizziness, erythema, headache, nausea, pain exacerbated, pruritus (itching), rash, and rash erythematous.
The FDA-approved dosing for Lidoderm is up to three patches applied for up to 12 hours within a 24-hour period. Lidoderm has not been approved by the FDA for any indications other than for the relief of pain associated with PHN, and its safety and efficacy in other indications have not been established.
