Neurochem submits NDA for Fibrillex(TM)

ECUBLENS, Switzerland, Feb. 13 (HSMN NewsFeed) - Neurochem (International) Limited (Neurochem), a wholly-owned subsidiary of Neurochem Inc. (NASDAQ: NRMX ; TSX: NRM ), announces today that the Company has submitted to the U.S. Food and Drug Administration (FDA) the final modules of its new drug application (NDA) for eprodisate (Fibrillex(TM)). The Company is seeking marketing approval of its investigational product candidate Fibrillex(TM) for the treatment of Amyloid A (AA) amyloidosis. The submission announced today completes this "rolling" NDA that was initiated last August, under the Continuous Marketing Application (CMA) Pilot 1 program. The FDA agreed in June 2005 to file and review the NDA.

AA amyloidosis is a progressive and fatal condition that 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 by AA amyloidosis, and progression to dialysis and End Stage Renal Disease is the most common cause of death in this disease. New approaches to treatment for AA amyloidosis are urgently needed due to lack of specific therapies. Fibrillex has received Orphan Drug Designation status in the United States as it is estimated that there are about 20,000 patients in North America.

"Completion of this application to the FDA for Fibrillex(TM) marks a very important milestone in Neurochem's progression towards its mission of bringing novel and innovative drugs to market thereby addressing serious and unmet medical needs," said Dr. Francesco Bellini, Chairman, President and Chief Executive Officer. "We believe that the NDA package supports the clinically and statistically meaningful effect of this product candidate on the preservation of kidney function in this patient population and its benign safety profile," he added.

"Effective treatment for AA amyloidosis is an important unmet medical need," said Laura M. Dember, M.D., Nephrologist and Associate Professor of Medicine at Boston University School of Medicine. Dr. Dember was a principal investigator for Neurochem's Phase II/III clinical trial. "Patients with this disease often progress to end-stage renal failure, and many die. There is currently no treatment directed specifically at AA amyloidosis. This drug has the potential to provide a much needed therapeutic solution for this devastating illness."

About the Phase II/III clinical trial

The Phase II/III clinical trial for Fibrillex(TM) was a two-year, international, multi-center, randomized, double-blind, placebo-controlled, and parallel-designed trial to evaluate the safety and efficacy of Fibrillex(TM) in patients suffering from AA amyloidosis. Neurochem enrolled 183 patients for this trial, which was conducted at 27 sites located across North America, Europe and Israel.

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

This news release contains forward-looking statements regarding eprodisate (Fibrillex(TM)), as well as regarding continuing and further development efforts. These statements are based on the current analysis and expectations of management. Drug development necessarily involves numerous risks and uncertainties, which could cause actual results to differ materially from this current analysis and these expectations. Analysis regarding the results of clinical trials may not provide definitive results regarding safety, tolerability or therapeutic benefits. Even if all the endpoints sought in the clinical trials were met (which is not certain), there is no certainty that regulators would ultimately approve Fibrillex(TM) for sale to the public. Risks and uncertainties may include: failure to demonstrate the safety, tolerability and efficacy of our product, the expense and uncertainty of obtaining regulatory approval, including from the FDA, and the possibility of having to conduct additional clinical trials. Further, even if regulatory approval is obtained, therapeutic products are generally subject to: stringent on-going governmental regulation, challenges in gaining market acceptance, and competition. Neurochem does not undertake any obligation to publicly update its forward-looking statements, whether as a result of new information, future events, or otherwise.
