    SAN DIEGO, Feb. 10 /PRNewswire-FirstCall/ -- Vical Incorporated
(Nasdaq: VICL) today reported revenues of $1.7 million for the fourth quarter
which ended December 31, 2003, compared with revenues of $0.5 million for the
fourth quarter of the prior year.  Revenues for the full year 2003 were
$8.1 million compared with $7.0 million for the full year 2002.  Results for
the full year 2003 reflected higher grant and contract manufacturing revenues,
partially offset by lower license and milestone payments.
    The net loss for the fourth quarter of 2003 was $6.9 million or $0.35 per
share, compared with a net loss of $7.5 million or $0.37 per share for the
fourth quarter of 2002.  For the full year 2003, the company reported a net
loss of $24.5 million or $1.22 per share compared with a net loss of
$27.9 million or $1.39 per share for 2002.  The reported full-year net losses
included a $0.5 million write-down in 2003, and a $4.2 million write-down in
2002, of the company's investment in Corautus Genetics Inc., formerly Vascular
Genetics Inc.  Higher revenues and lower general and administrative spending
for the full year were essentially offset by lower returns on investments and
increased spending on research and development.  At December 31, 2003, the
company had cash, cash equivalents and marketable securities of $85 million
compared with $112 million at December 31, 2002.
    Vijay B. Samant, Vical's President and Chief Executive Officer, said,
"2003 was a very important year for Vical, with completion of patient
enrollment and encouraging interim data in our Allovectin-7(R) melanoma
immunotherapy program and good progress in our two lead infectious disease
vaccine programs.  We will report on continued advances throughout 2004 in our
independent and partnered programs.  Our net loss was in line with our
expectations, coming in at the low end of our forecast range of $24 million to
$28 million.  We expect our contract manufacturing activity to increase
beginning in the second half of the year, and our projected net loss for 2004
is between $26 million and $29 million."

    Allovectin-7(R)
    Vical has initiated discussions with the U.S. Food and Drug Administration
(FDA) regarding whether the results from the company's high-dose Phase 2 trial
could potentially support accelerated approval for marketing Allovectin-7(R)
for use in certain patients with recurrent and/or otherwise treatment-
intolerant metastatic melanoma.  The company expects these discussions will
lead to two formal End-of-Phase 2 (EOP2) meetings within the next few months.
The Product EOP2 meeting would focus on manufacturing and other product-
related topics.  The Clinical EOP2 meeting would focus on clinical and non-
clinical data supporting claims of efficacy and safety.  In preparation for
the Clinical EOP2 meeting, the company took a snapshot, in November 2003, of
the efficacy data from the complete high-dose cohort after all enrolled
patients had an opportunity to complete two cycles of Allovectin-7(R) therapy.
Based on the outcome of these two meetings, by the end of the second quarter
of 2004, Vical expects to finalize the company's approach to seeking market
approval of Allovectin-7(R).
    In February 2001, the company began a high-dose Phase 2 trial evaluating
the Allovectin-7(R) gene-based immunotherapeutic for patients with Stage III
or IV melanoma, who have few other treatment options.  The company presented
unaudited data at the annual meeting of the American Society of Clinical
Oncology (ASCO) in May 2003 from interim analyses performed in early March
2003 for the first 91 patients in the high-dose cohort, indicating an
objective response rate of 13 percent with continued excellent safety and
tolerability.  An update in July 2003 yielded an estimated median duration of
response of at least 6.4 months.  Patient enrollment was completed in July
2003 with a total of 133 patients, including 6 in an initial dose-escalation
cohort and 127 in the high-dose cohort.  Key clinical data on the full high-
dose cohort are expected to be presented in a scientific meeting in June 2004.

    CMV
    The company made significant preclinical progress in 2003 with its DNA-
based immunotherapeutic vaccine against cytomegalovirus (CMV) and expects to
begin clinical testing in the next few months in support of an initial
application in bone marrow transplant patients.  The majority of the required
preclinical testing has been completed; a bivalent vaccine encoding two known
immunogenic CMV proteins has been formulated with a poloxamer; and clinical
supplies have been manufactured.  The company has established working
relationships with some of the country's leading transplant centers, which
have contributed to the trial design and may participate in upcoming CMV
vaccine trials.

    Anthrax
    The company's second-generation, bivalent, cationic-lipid formulated
anthrax vaccine is designed to provide broader protection against weaponized
forms of anthrax than the currently approved anthrax vaccine.  Preclinical
data from the anthrax vaccine program demonstrated complete protection of
rabbits at 7.5 months post-vaccination against a lethal aerosolized spore
inhalation challenge.  The company plans to proceed with human clinical
testing of the vaccine pending completion of ongoing preclinical studies and
contingent on government funding, which directly depends on the priorities and
appropriations for the U.S. government's Project BioShield.  Work continues on
the non-clinical development of the anthrax vaccine, which is being supported
by a three-year, $5.7 million grant awarded by the NIH in July 2003.

    NIH/VRC Collaborations
    In February 2004, Vical received orders for approximately $6 million for
production of DNA vaccines under two subcontracts managed by SAIC-Frederick,
Inc., for the Vaccine Research Center at the National Institute of Allergy and
Infectious Diseases of the National Institutes of Health.  Production will
begin in the first half of 2004 in the company's existing Eastgate
manufacturing facility, but the majority will be completed in the second half
of 2004 in the company's new Pacific Center Court manufacturing facility.
Additional orders may be placed under both subcontracts.

    Outlook
    The company expects to achieve the following operational milestones in
2004:

     *  Formal End-of-Phase 2 meetings with the FDA within the next few months
        to determine whether the high-dose Phase 2 trial could potentially
        support accelerated approval of Allovectin-7(R) for certain patients
        with recurrent and/or otherwise treatment-intolerant metastatic
        melanoma,

     *  Presentation of key clinical data from the Allovectin-7(R) high-dose
        Phase 2 trial as of November 2003 at a scientific meeting in June,

     *  Start of the initial CMV vaccine human safety trial within the next
        several months,

     *  Continued progress with non-clinical development of the anthrax
        vaccine under the existing NIH grant, and potential additional
        government funding to support an advance into human clinical testing,

     *  A new product development program in solid tumors as an initial
        application of electroporation technology by year-end 2004,

     *  Contract manufacturing in the new facility in the second half of the
        year, and

     *  At least one new collaboration in 2004.
