        OXiGENE Reports Second-Quarter 2003 Financial Results
             and Operational Goals for Remainder of Year

    WATERTOWN, Mass.--(BUSINESS WIRE)--Aug. 8, 2003--OXiGENE, Inc.
(NASDAQ: OXGN, XSSE: OXGN), a leader in the development of
biopharmaceutical compounds designed to target aberrant blood vessels
in solid tumors and ocular neovascular diseases, today reported
financial results for the second quarter and six months ended June 30,
2003.
    "In recent months we have announced numerous financial and
operational accomplishments," said OXiGENE President and Chief
Executive Officer Fred Driscoll. "Notable among these achievements,
CA4P has entered new human clinical trials in cancer and
ophthalmology, creating potential new opportunities for our vascular
targeting technology in large and growing markets. In addition, CA4P
received the U.S. Food and Drug Administration's orphan drug and fast
track designations, which we view as important milestones as we
advance our lead compound forward.
    "These events provided the impetus that enabled us to close in
June on a $15 million private placement of common stock that
strengthens our balance sheet and enhances our overall financial
position," Driscoll said. "We are now poised to advance our lead
compound aggressively toward commercialization and to continue the
development of our exciting pre-clinical pipeline."

    Financial Discussion

    Net loss for the second quarter of 2003 was $1.8 million, or $0.14
per share, compared with a net loss of $2.7 million, or $0.23 per
share, in the second quarter of 2002. For the first six months of 2003,
the net loss was $3.3 million, or $0.26 per share, compared with a net
loss of $6.9 million, or $0.58 per share, for the first six months of
2002. Based on its current expense run-rate, OXiGENE expects its
full-year 2003 net loss to be approximately $7 million. The Company
reported a net loss of $11 million for full-year 2002.
    As of June 30, 2003, OXiGENE had $22.9 million in cash and
marketable securities, compared with $11.8 million as of December 31,
2002.
    "The continued improvement in our bottom line is a direct result
of the focused drug-development strategy we initiated in late 2001,"
Driscoll said. "Concentrating on vascular targeting, which we believe
will offer the greatest potential return for our shareholders, has
allowed us to reduce total expenses in 2003 by approximately 60
percent year-to-date compared with the same period in 2002. We
continue to be selective about how and where we allocate our clinical
and pre-clinical resources. As evidenced by our relationships with
such pre-eminent organizations as The Foundation Fighting Blindness,
the National Cancer Institute and Cancer Research UK, we are taking
advantage of opportunities to secure alliances that will help to fund
our programs and build our pipeline of compounds."

    Recent highlights:

    --  Private placement: Three large institutional investors
        purchased 1,500,000 shares of the Company's Common Stock at
        $10 per share. OXiGENE received approximately $14 million from
        the sale after the deduction of commissions and expenses. The
        three institutional investors also received warrants for a
        term of two years to purchase an aggregate of 375,000 shares
        of OXiGENE Common Stock, which will be exercisable at a price
        of $15 per share in cash.

    --  Fast-track designation: The U.S. Food and Drug Administration
        granted the fast-track designation to OXiGENE's lead compound,
        Combretastatin A4 Prodrug, for the treatment of anaplastic
        thyroid cancer. CA4P is currently in Phase II human trials in
        this indication. The fast-track program is intended to foster
        the development of new drugs designed to treat
        life-threatening conditions for which there is no approved
        therapy. This designation creates opportunities for OXiGENE to
        meet with and receive input from the agency in the design of
        clinical efficacy studies needed to support market approval.

    --  Orphan-drug status: The FDA approved OXiGENE's application to
        classify CA4P as an "orphan drug" for the treatment of
        anaplastic thyroid cancer. In addition, the agency broadened
        the orphan drug designation for CA4P to include the treatment
        of medullary, Stage IV papillary and Stage IV follicular
        thyroid cancers. OXiGENE estimates a prevalence of
        approximately 58,000 people in the United States with one of
        these four stages or sub-types of cancer.

    --  New clinical trials: CA4P moved into new clinical trials in
        cancer and ophthalmology. In the United Kingdom, the
        investigational compound is being studied in a Phase I/II
        combination with a standard-of-care chemotherapeutic regimen
        (carboplatin and paclitaxel) in women with advanced ovarian
        cancer. CA4P also is being evaluated in a Phase I/II study in
        patients with wet age-related macular degeneration, the cause
        of significant vision loss in between 2 million and 3 million
        Americans. This trial is being conducted at The Johns Hopkins
        University School of Medicine's Wilmer Eye Institute in
        Baltimore. CA4P is now in a total of five human clinical
        studies.

    --  Peer-reviewed pre-clinical research: Investigators writing in
        the August 2003 issue of the journal Investigative
        Ophthalmology and Visual Science reported the results of
        independent animal studies into the potential role of CA4P in
        preventing and treating certain retinal degenerative diseases.
        The pre-clinical studies showed that CA4P suppresses
        development and induces regression of choroidal
        neovascularization, a condition that leads to severe vision
        loss.

    --  Cancer Research UK Alliance: Cancer Research UK (CRUK) is
        collaborating with OXiGENE on the final pre-clinical
        development of OXi4503, one of the Company's three
        second-generation vascular targeting agents. CRUK, one of the
        world's largest cancer research organizations, plans to move
        the compound into Phase I clinical trials next year.

    Business Outlook

    Commenting on the Company's clinical development outlook for the
remainder of 2003, Driscoll said, "Seven months into 2003, I am proud
of the fact that we already have accomplished many of the clinical and
pre-clinical objectives we announced in tandem with our fourth-quarter
results in February. Patient accrual is on schedule in the Phase II
and Phase I/II oncology studies of CA4P, and we expect to initiate a
fifth cancer trial before the end of the year. Recruitment also has
begun in the wet AMD trial at Johns Hopkins, the first study of a
vascular targeting agent in a non-life-threatening indication. In
addition, Cancer Research UK is moving ahead with final pre-clinical
testing of our lead second-generation drug candidate, OXi4503, which
is on pace to enter the clinic in 2004. Development also continues on
our other pre-clinical compounds, OXi6197 and OXi8007, giving us a
strong pipeline of Vascular Targeting Agents to complement CA4P.
    "On the business side, we remain focused on identifying potential
licensing opportunities for CA4P," Driscoll continued. "The clinical
development progress we have made during the past 12 months has
demonstrated the potential breadth of our vascular targeting platform.
We continue to engage in positive discussions with prospective
licensing partners in both oncology and ophthalmology."

    About OXiGENE

    OXiGENE is the world leader in the development of novel
biopharmaceutical compounds called vascular targeting agents (VTAs),
which are designed to block the flow of blood that supplies solid
cancer tumors and other abnormal vasculature, while leaving healthy
cells intact. OXiGENE's lead VTA, Combretastatin A4 Prodrug, has
advanced into Phase II and combination clinical trials in cancer
patients in the United States and Europe. The investigational compound
also is being evaluated in an ophthalmic study in patients with wet
age-related macular degeneration. Three other OXiGENE VTAs, OXi4503,
OXi6197 and OXi8007, are in pre-clinical development. For more
