Neurochem Moves Eprodisate (Kiacta) Drug Development Program Forward for Amyloid A Amyloidosis

ECUBLENS, SWITZERLAND, March 13, 2008 /PRNewswire-FirstCall/ - Neurochem (International) Limited (Neurochem), a wholly-owned subsidiary of Neurochem Inc. , announces that the Company is taking new initiatives to pursue the drug development program for its investigational product candidate, eprodisate (Kiacta), to obtain market approval for the treatment of Amyloid A (AA) amyloidosis. Neurochem's decision to build upon its eprodisate (Kiacta) asset and take steps to initiate a second Phase III clinical trial is based principally on the fact that AA amyloidosis is a life-threatening disease for which there is no specific treatment, on the data obtained from the first Phase II/III clinical trial, which yielded promising efficacy results on the study endpoints, on the benign safety profile of eprodisate (Kiacta) in patients diagnosed with AA amyloidosis, and on its discussions with the regulatory agencies and related scientific advisory committees. As part of the approval process for the investigational product candidate, both the regulatory agencies in the United States and in the European Union recommended an additional confirmatory efficacy Phase III clinical trial, which will have a target significance level (p-value) of 0.05 rather than the p-value of 0.01, which had been required for an approval based on a single efficacy study. Based on these recommendations, the Company will enter into discussions with the U.S. Food and Drug Administration (FDA) and with the European Medicines Agency (EMEA) to reach agreement on the terms for an approval of eprodisate (Kiacta) for the treatment of AA amyloidosis. As part of this strategic decision, the Company is also announcing that it is withdrawing its current marketing applications for eprodisate (Kiacta) in the United States, the European Union and Switzerland.

"This strategy reflects the advice the Company has received from the regulatory authorities about its marketing applications, and is in line with our efforts over the past two years and allows the Company to pursue its objective of making Kiacta available to patients as soon as possible. The FDA and EMEA have both acknowledged that the first Phase II/III clinical trial provided some evidence of the effectiveness of Kiacta in the treatment of the renal manifestations of amyloidosis. Accordingly, we look forward to productive discussions with the regulatory agencies and hope to initiate the second Phase III study in the very near future," said Dr. Francesco Bellini, Chairman, President and Chief Executive Officer of Neurochem Inc.

The applications for marketing authorization for eprodisate (Kiacta) were submitted in the United States, the European Union and in Switzerland in February, September and November 2006, respectively.

About eprodisate (Kiacta)

Eprodisate (Kiacta) was investigated in an international, randomized, double-blind, placebo-controlled, and parallel-designed Phase II/III clinical trial in which 183 AA amyloidosis patients were enrolled at 27 sites around the world (Eprodisate for AA Amyloidosis Trial, EFAAT). Patients who completed the clinical trial were eligible for enrollment in an ongoing open-label extension study, some of whom have now been receiving eprodisate (Kiacta) for more than six years. The completion of the extension study is scheduled for April 2008. Neurochem Inc. sponsored the EFAAT study.

Eprodisate (Kiacta) has received orphan drug status in the United States and the European Union, which normally provide seven and ten years of market exclusivity, respectively, upon regulatory approval.

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/end-stage renal disease is the most common clinical manifestation 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.
