Variagenics Announces Second Quarter Financial
Results

CAMBRIDGE, Mass., Aug. 2 /PRNewswire/ -- Variagenics, Inc. (Nasdaq: VGNX - news), a leader in pharmacogenomics,
today announced results for the second quarter and six months ended June 30, 2001.

For the second quarter of 2001, revenues were $0.9 million, compared with $0.1 million for the same period in 2000. The
second quarter net loss excluding non-cash equity compensation was $4.2 million, or $0.18 per share (basic and diluted). This
compares with a net loss of $3.0 million, or $3.20 per share (basic and diluted), for the comparable quarter ended June 30,
2000.

For the six months ended June 30, 2001, Variagenics reported revenues of $2.0 million, compared with $0.3 million for the
same period in 2000. The net loss for the first six months of 2001 excluding non-cash equity compensation was $6.8 million, or
$0.29 per share (basic and diluted). For the comparable six-month period of 2000, the net loss excluding non-cash equity
compensation was $5.5 million, or $6.61 per share.

The Company ended the second quarter with $91.1 million in cash and marketable securities.

Taylor J. Crouch, Variagenics' President and CEO, said, ``We are directing the application of our pharmacogenomics platform
toward the development and commercialization of molecular diagnostics. Our approach is to discover a set of proprietary
genetic markers and validate their clinical utility to create patented gene-based tests predictive of drug response.''

``Much of our internal research is focused on cancer, an area where we believe the use of molecular diagnostics can
dramatically change treatment outcomes,'' continued Crouch. ``Today, for example, typical drugs used for colon cancer are
effective in less than thirty percent of patients. Variagenics has aggressively focused on generating a proprietary set of markers
that may change the way cancer chemotherapeutics are prescribed. We are developing marker sets that will go well beyond
SNPs and haplotypes to include indicators of LOH and mRNA expression.''

Recent Highlights:

Cancer Programs:

* In support of its focus on cancer research and its emphasis on genetic
pathways, Variagenics performed a comprehensive analysis of a critical
pathway involved in the efficacy and toxicity of leading cancer
therapeutics. This pathway, involving folate metabolism, covers a
class of chemotherapeutic agents based on 5-Fluorouracil (5-FU) used
for colon and rectal cancer. Variagenics will be showcasing its 5-FU
pathway analysis at the Drug Discovery Technology Conference in Boston
beginning August 13, 2001.

* As part of its cancer research platform, Variagenics devised
methodologies to correlate loss of heterozygosity (LOH) with drug
response and developed assays that may ultimately lead to molecular
diagnostic products for conducting LOH analysis.

* Variagenics announced the issuance of a second U.S. patent involving
Methylene-tetrahydrofolate Reductase (MTHFR). This patent plays an
important role in Variagenics' pathway strategy, which considers that
more than one gene is involved in an individual's response to drugs and
diagnostics. The patent was exclusively licensed from McGill
University, where Variagenics' advisor, Dr. Rima Rozen, has been
identifying variant forms of the gene that affect folate metabolism and
has been studying the importance of MTHFR in cancer and a variety of
other diseases.

Molecular Diagnostic Development:

* Intellectual property claiming the use of SNPs, haplotypes and other
genetic markers for predicting drug response is the basis for the
high-value molecular diagnostics that Variagenics is creating. The
Company has analyzed variation in over 5,000 genes believed to be
involved in drug response and has substantially increased the numbers
of functional genetic markers for which it has filed patents.
Variagenics now owns or has exclusive license to 18 U.S. patents and
has 108 U.S. patents pending.

* Variagenics announced the issuance of a third U.S. patent for
apolipoprotein E (ApoE) entitled "Methods for determining the
prognosis of a patient with neurological disease." The patent
describes a method for determining the prognosis of a patient diagnosed
with Parkinson's disease, multiple sclerosis, stroke and other brain
diseases. The claims in this patent extend Variagenics' rights to
nervous system disorders beyond dementia and cognitive impairment, and
articulate the clinical spectrum of pharmacogenomic utility from
clinical trials to diagnostic tests.

* Variagenics furthered its research involving a novel, proprietary
laboratory technique for measuring haplotypes. This molecular
haplotyping technology is Variagenics' high-throughput method for
defining haplotypes in clinical samples, and provides Variagenics with
a unique and powerful tool for the pharmacogenomic analysis of genetic
variation. Molecular haplotyping is an essential component of several
ongoing clinical research studies, including internal and partnered
(VIP) programs. One of Variagenics' in-house studies is aimed at
demonstrating the superiority of molecular haplotyping over simple SNP
analysis and computational haplotyping.

Variagenics will hold a conference call at 11:00 a.m. Eastern Time today. Taylor J. Crouch, President and CEO, will lead the
call. Richard P. Shea, Vice President, CFO and Treasurer, and Colin W. Dykes, Ph.D., Vice President, Research, also will
participate.

Variagenics, Inc. applies its pharmacogenomic technologies to the discovery, development and commercialization of
personalized drugs and companion molecular diagnostic products. Using a drug pathway approach, the Company identifies
therapeutically important genetic markers, including SNPs, haplotypes and LOH indicators. This information is then applied to
clinical programs to enhance drugs in development, and ultimately to the creation of diagnostics for predicting patient response
to drugs.

Antigens that are tumor specific yet retained by tumor cells despite tumor progression offer stable and specific targets for
immunologic and possibly other therapeutic interventions. Therefore, we have studied two CD4+ T cell–recognized
tumor-specific antigens that were retained during evolution of two ultraviolet-light–induced murine cancers to more aggressive
growth. The antigens are ribosomal proteins altered by somatic tumor-specific point mutations, and the progressor (PRO)
variants lack the corresponding normal alleles. In the first tumor, 6132A-PRO, the antigen is encoded by a point-mutated L9
ribosomal protein gene. The tumor lacks the normal L9 allele because of an interstitial deletion from chromosome 5. In the
second tumor, 6139B-PRO, both alleles of the L26 gene have point mutations, and each encodes a different tumor-specific
CD4+ T cell–recognized antigen. Thus, for both L9 and L26 genes, we observe "two hit" kinetics commonly observed in genes
suppressing tumor growth. Indeed, reintroduction of the lost wild-type L9 allele into the 6132A-PRO variant suppressed the
growth of the tumor cells in vivo. Since both L9 and L26 encode proteins essential for ribosomal biogenesis, complete loss of
the tumor-specific target antigens in the absence of a normal allele would abrogate tumor growth.
