Acorda Therapeutics Announces Acquisition of Two Neuropathic Pain Assets

Acorda Therapeutics Announces Acquisition of Two Neuropathic Pain Assets

Published: July 9, 2013

— Acorda Therapeutics, Inc. (Nasdaq: ACOR) today announced that it has acquired two neuropathic pain management assets from NeurogesX, Inc. (OTCBB: NGSX). Qutenza® is approved by the U.S. Food and Drug Administration (FDA) for the management of neuropathic pain associated with postherpetic neuralgia. The Company also acquired NP-1998, a Phase 3 ready, prescription strength capsaicin topical solution, being assessed for the treatment of neuropathic pain. NP-1998 was previously referred to as NGX-1998.

"The acquisition of Qutenza and NP-1998 enables us to expand into the area of neuropathic pain management. We plan to support Qutenza with our existing medical and commercial infrastructure, which includes one of the industry's best neurology sales forces," said Ron Cohen, M.D., Acorda's President and CEO. "In addition, we will leverage our neurology expertise to evaluate NP-1998 for the treatment of neuropathic pain, with an initial emphasis on painful diabetic neuropathy. This adds another potentially important, late stage product to our pipeline."

Acorda made an approximately $8 million payment to acquire development and commercialization rights for Qutenza and NP-1998 in the United States, Canada, Latin America and certain other territories, including $7 million paid to NeurogesX and approximately $900,000 for certain assumed accounts payable. Acorda will also make up to $5 million in payments contingent upon the achievement of certain regulatory and sales milestones related to NP-1998. Astellas Pharma Europe Ltd. has exclusive commercialization rights for Qutenza in the European Economic Area (EEA) including the 27 countries of the European Union, Iceland, Norway, and Liechtenstein as well as Switzerland, certain countries in Eastern Europe, the Middle East and Africa. Astellas also has an option to develop NP-1998 in those same territories.

Qutenzais a dermal patch containing 8% prescription strength capsaicin that is applied once every three months for the management of neuropathic pain associated with postherpetic neuralgia, also known as post-shingles nerve pain. The drug was approved by the U.S. Food and Drug Administration in 2010, and had net sales of $2.6 million in 2011. NeurogesX discontinued active promotion of the product in March 2012; net sales were approximately $2.4 million through the end of the third quarter of 2012. Acorda plans to support Qutenza in the United States using the Company's existing commercial organization, including its specialty neurology sales force of approximately 100 sales professionals, as well as its medical and safety reporting infrastructure.

NP-1998 is a topical solution containing 20% prescription strength capsaicin under clinical development as a treatment for pain associated with neuropathic pain conditions such as painful diabetic neuropathy (PDN).

Astellas is currently conducting clinical trials of Qutenza including a Phase 3 trial to assess its use in the treatment of pain associated with PDN. Under the terms of the agreement, Acorda will have rights to review data from that trial, and the companies may also collaborate and/or share costs of future clinical trials.

Postherpetic Neuralgia (PHN) or Post-Shingles Nerve Pain

Postherpetic neuralgia (PHN), also known as post-shingles nerve pain, is chronic pain resulting from shingles, a viral infection caused by the same virus that causes chickenpox. There are approximately one million new cases of shingles in the United States each year.

Shingles is characterized by an outbreak of rash or blisters on the skin and nerve pain that typically resolves within several weeks. However, up to one-third of people who have a shingles outbreak experience PHN, which can continue for months or years after the shingles rash has healed.

About Painful Diabetic Neuropathy (PDN)

Diabetes is a group of diseases marked by high levels of blood glucose resulting from defects in insulin production, insulin action or both. According to the National Institute of Diabetes and Digestive Kidney Diseases (NIDDK), more than 23 million people in the U.S. have diabetes.

Painful diabetic neuropathy is a common complication of diabetes characterized by chronic pain that results from damage to nerves due to poor circulation and high blood sugar. People with diabetes can develop nerve problems at any time, but risk rises with age and longer duration of diabetes. Diabetic neuropathies also appear to be more common in people who have problems controlling their blood glucose, as well as those with high levels of blood fat and blood pressure, and those who are overweight.

Qutenza Important Safety Information

Tell your healthcare provider if you are experiencing pain; a cool compress or medicine for the pain can be provided to help lessen your discomfort.
  • Qutenza can cause serious side effects including pain and increases in blood pressure during or right after treatment.
  • Your healthcare provider should check your blood pressure during treatment with Qutenza.
  • Patients who have high blood pressure that is not well controlled by medicine, or who have had recent heart problems, stroke, or other vascular problems, may be at increased risk and should discuss with their doctor whether Qutenza is right for them.

Side Effects:

  • In clinical studies, the most common drug-related side effects of Qutenza, which occurred in 5% or more of patients, included redness, pain, small bumps, and itching. These side effects occurred at the patch application site.
  • You should tell your doctor if any side effects bother you or do not go away.

These are not all the side effects of Qutenza. For more information, ask your healthcare provider or pharmacist or visit www.qutenza.com.
