Neurochem, Inc. Marketing Authorization Application For Kiacta(TM) Accepted For Review By EMEA

ECUBLENS, Switzerland, Sept. 28 /PRNewswire-FirstCall/ - Neurochem (International) Limited (Neurochem), a wholly-owned subsidiary of Neurochem Inc. , announces today that its Marketing Authorization Application (MAA) for eprodisate (Kiacta(TM); formerly Fibrillex(TM)) has been validated by the European Medicines Agency (EMEA), which confirms that the regulatory review has started. The Company is seeking marketing approval of its investigational product candidate, Kiacta(TM), for the treatment of Amyloid A (AA) amyloidosis in the European Union (EU).

The MAA for Kiacta(TM) will be reviewed under the Centralized Procedure, where marketing authorization is applied for all EU Member States (numbering 25 countries today), plus Norway and Iceland. Kiacta(TM) has been designated as an Orphan Medicinal Product in Europe, which normally provides ten years of market exclusivity upon regulatory approval.

"Neurochem looks forward to working with the European Authorities as they begin the review process for Kiacta(TM) as a potential and specific treatment for AA amyloidosis," said Dr. Francesco Bellini, Chairman, President and Chief Executive Officer of Neurochem Inc. "We remain committed to the advancement of this product candidate with the hope of making it available as soon as possible to the doctors and the patients who could benefit from Kiacta(TM)."

In August 2006, Neurochem Inc. received an approvable letter from the U.S. Food and Drug Administration (FDA) for Kiacta(TM) for the treatment of AA amyloidosis. Neurochem Inc. plans to respond to the FDA and submit an amendment to the New Drug Application shortly.

Neurochem has an exclusive collaboration and distribution agreement for Kiacta(TM) with Centocor, Inc.

About Kiacta(TM)

Kiacta(TM) was investigated in a landmark international, randomized, double-blind, placebo-controlled, and parallel-designed clinical trial in which 183 patients were enrolled at 27 sites around the world. Patients who completed the clinical trial were eligible for enrollment in an ongoing open-label extension study.

About Amyloid A (AA) amyloidosis

A progressive and fatal condition, AA amyloidosis occurs in a proportion of patients with chronic inflammatory disorders, chronic infections and inherited diseases such as Familial Mediterranean Fever. The kidney is the organ most frequently affected and progression to dialysis and end stage renal disease is the most common cause of death in this disease. Currently, there is no approved therapy to treat AA amyloidosis and about half of all patients diagnosed with the disease die within five years of diagnosis.
