Neurochem's eprodisate (KIACTA(TM)) PDUFA date extended three months by FDA

    ECUBLENS, Switzerland, April 11 /CNW Telbec/ - Neurochem (International)
Limited (Neurochem), a wholly owned subsidiary of Neurochem Inc.
(NASDAQ:   NRMX; TSX: NRM), announces that it received notification from the
United States Food and Drug Administration (FDA) that the action date for
FDA's review of the New Drug Application (NDA) for eprodisate (KIACTA(TM)) for
the treatment of Amyloid A (AA) amyloidosis, has been extended to July 16,
2007. Previously, the action date under the Prescription Drug User Fee Act
(PDUFA) for the eprodisate (KIACTA(TM)) NDA was April 16, 2007.
    The FDA is extending the PDUFA goal date by three months to provide time
for a full review of an amendment to the eprodisate (KIACTA(TM)) NDA submitted
by Neurochem Inc. in February 2007. This additional submission is considered
by the FDA to be a major amendment to the NDA, allowing an extension of the
action date.

    About eprodisate (KIACTA(TM))

    Eprodisate (KIACTA(TM)) was investigated in a landmark international,
randomized, double-blind, placebo-controlled, and parallel-designed 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(TM))
for more than five years. Eprodisate (KIACTA(TM)) has received orphan drug
status in the United States, the European Union and in Switzerland.

    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.
    The EFATT study was sponsored by Neurochem Inc.
