     TO SUPPORT ITS SYNTHETIC VACCINE PROGRAM FOR ALZHEIMER'S DISEASE

                       NEUROCHEM FORMS STRATEGIC ALLIANCE
                  WITH THE NATIONAL RESEARCH COUNCIL OF CANADA
                        AND ANNOUNCES LICENSING AGREEMENT
                    WITH PRAECIS PHARMACEUTICALS INCORPORATED

         -- NEUROCHEM TAKES MAJOR STEP FORWARD IN ITS EFFORTS TO PREVENT
                        AND TREAT ALZHEIMER'S DISEASE --


MONTREAL, CANADA, JANUARY 20, 2003 -- Neurochem Inc. (NASDAQ: NRMX, TSX: NRM)
announced today that the Company is advancing its efforts to prevent and treat
Alzheimer's Disease (AD) by forging a strategic alliance with the National
Research Council of Canada's Institute for Biological Sciences, (NRC-IBS), and
more specifically with Dr. Harold J. Jennings, a world leader in the development
of innovative conjugated vaccines. Neurochem also announced today that it has
entered into a licensing agreement with PRAECIS PHARMACEUTICALS INCORPORATED, a
leading biopharmaceutical company, relating to certain a amyloid peptides for
use in the development of a novel synthetic vaccine to prevent and treat AD.
With a promising drug candidate, Alzhemed(TM), currently in clinical development
for AD, Neurochem is reinforcing its commitment to the prevention and treatment
of AD through these relationships, and its focus on neurological disorders.
Financial terms of the agreements were not disclosed but all future commercial
rights in therapies developed by Neurochem under the agreements will belong to
Neurochem.

NRC-IBS' Dr. Jennings is one of Canada's premier researchers in the vaccine
field. One of Dr. Jennings' greatest achievements was the development of a
technology that can be used to produce innovative conjugated vaccines against
meningitis A, B and C, or the bacteria Haemophilus influenzae. The vaccines for
meningitis C and Haemophilus influenzae are currently on the market, preventing
these diseases in millions of children in North America and Europe.

Dr. Francesco Bellini, Chairman and CEO of Neurochem, has stated that "With
these important relationships in place, Neurochem intends to address AD at its
different stages from its very early symptoms through the entire disease course.
Since AD is a complex disease affecting multiple areas of the brain, Neurochem
is using a comprehensive approach by working to develop a 'cocktail' solution
and a multi-product treatment for the disease."

ABOUT THE RELATIONSHIPS

Neurochem has concluded this strategic alliance with the National Research
Council of Canada and Dr. Jennings to collaborate on the discovery and
assessment of certain vaccine approaches in animal models, and work towards the
development of a specific vaccine using amyloid protein fragment conjugates.
This collaboration also includes the possibility of preclinical and clinical
development as well as future commercialization in the field of
A(beta)-peptide-protein conjugates. Through the licensing agreement with
PRAECIS, Neurochem is expanding its pool of intellectual property relating to
specific A(beta)-derived peptide sequences.

Neurochem's expertise in the field of amyloid and AD coupled with Dr. Jennings'
world renowned expertise in conjugated synthetic vaccine development brings
strength to the early studies that Neurochem has completed on a vaccine approach
to the prevention and treatment of this serious disease.

ABOUT THE VACCINE

Neurochem's vaccine program targets a specific region of the A(beta) protein.
This fragment, when made of D amino acids conjugated to a carrier, generates an
immune response where antibodies recognize only the soluble form of the A(beta)
protein. Preliminary experiments at Neurochem's laboratories have shown that
this type of conjugates protect mice as efficiently as the reported vaccine made
with the full A(beta) protein. One advantage of Neurochem's approach is that the
antibodies do not recognize plaques and therefore could help circumvent the risk
of developing brain inflammation as was seen with the full A(beta) protein
vaccine. Neurochem's vaccine technology teamed with NRC's (Dr. Jennings)
know-how on vaccine technology is expected to lead to the development of a safe
vaccine protecting humans against Alzheimer's Disease.

ABOUT NEUROCHEM

Neurochem is focused on the development and commercialization of innovative
therapeutics for neurological disorders. The Company's staged pipeline of
proprietary, disease-modifying, oral products addresses critical unmet medical
needs. Fibrillex(TM), designated an orphan drug, is in a Phase II/III clinical
trial for AA amyloidosis. Alzhemed(TM) has completed a Phase II clinical trial.
Cerebril(TM) is in a Phase II trial for the prevention of hemorrhagic stroke
caused by cerebral amyloid angiopathy. For additional information on Neurochem,
