              CYTRX REPORTS FOURTH QUARTER AND FISCAL 2003 RESULTS


LOS ANGELES, CA - MAY 14, 2004 - CytRx Corporation (Nasdaq: CYTRE) today
announced the results of its operations for the fourth quarter and fiscal year
ended December 31, 2003. The company has also now filed its Annual Report on
Form 10-K for 2003 with the SEC.

The company reported a net loss of $3.1 million, or $0.09 per share, for the
quarter ended December 31, 2003 compared to $2.5 million, or $0.12 per share,
for the same period in 2002. Net loss for the year ended December 31, 2003 was
$17.8 million, or $0.65 per share, compared to $6.2 million, or $0.39 per share
for the same period last year.



Research and development costs were $4.4 million for the year ending December
31, 2003, compared to $0.8 million for 2002.




Cash and cash equivalents and short-term investments at December, 2003 were
$11.6 million compared to $1.8 million at the end of 2002.

The majority of CytRx's expenses resulted from a strategic decision by the
company to focus the company's resources on the development of proprietary RNAi
technology for ALS, type 2 diabetes and obesity. In addition, and as previously
reported by the company, the company wrote-off its investment in Blizzard
Genomics and another development-stage genomics company. This non-cash write off
of $5.87 million was taken in the third quarter of 2003, and the company has now
filed an amended Form 10-Q to reflect the write-off being made in that quarter.

Commented Steven A. Kriegsman, President and CEO of CytRx, "2003 was an
absolutely pivotal year for the company that transformed CytRx into a leader in
the RNAi field. We licensed RNAi technology that we feel has the potential to
revolutionize the way ALS, type 2 diabetes and obesity may be treated. During
the year we funded world-class facilities and scientific talent to support this
initiative."

Mr. Kriegsman continued, "Thanks to two private placements, CytRx had a cash
position of approximately $12 million at the end of 2003, which gives us the
resources to start funding our pre-clinical development for our ALS, obesity and
type 2 diabetes programs. We further enhanced our capital structure by electing
not to invest further monies in two genomics companies that we felt did not fit
with our new corporate strategy."



Highlights for 2003 include:

        -       The company licensed RNAi technology from UMMS for the
                development of lead drug compounds for use in the treatment of
                obesity and type 2 diabetes. The research sponsored by CytRx is
                being led by Michael Czech, Ph.D., an internationally renowned
                authority in the field of obesity and type 2 diabetes and a
                founder of the company's CytRx Laboratories, Inc. (formerly
                known as Araios, Inc.) subsidiary.

        -       The company established an exclusive, worldwide, royalty-bearing
                license agreement with UMMS to use UMMS' RNAi technology to
                develop a treatment for a form of ALS.

        -       The company licensed from UMMS the exclusive worldwide
                commercial rights to a novel DNA-based HIV vaccine technology.
                Enrollment of volunteers for a Phase I study of an HIV vaccine
                that incorporates the company's technology commenced in April
                2004, and the company will acquire this vaccine after completion
                of the Phase I trial.

        -       The Company established a subsidiary, CytRx Laboratories, to
                develop orally active small molecule-based drugs to prevent,
                treat and cure obesity and type 2 diabetes. Mark A. Tepper,
                Ph.D., President of CytRx Laboratories, leads a team of world
                renowned scientific advisors who are working with this
                subsidiary.

        -       CytRx and Massachusetts General Hospital jointly initiated a
                research program for the use of RNAi in the development of an
                effective treatment for certain cases of ALS. The research
                program is led by Robert H. Brown, Jr., M.D., Ph.D., Director of
                the Cecil B. Day Laboratory for Neuromuscular Research at
                Massachusetts General Hospital.

        -       CytRx entered into an agreement to outlicense its co-polymer
                technologies, including FLOCOR, Opti-Vax and related
                anti-infective products, on an exclusive basis to SynthRx, Inc,
                a Houston-based biopharmaceutical company.

        -       During 2003, the company raised approximately $14 million from
                private placements.
