[CYTRX LOGO] FOR ADDITIONAL INFORMATION: CytRx Corporation: Carolyn French Director of Communications 310/826-5648 cfrench@cytrx.com Investor Relations Group: Lisa Lindberg/John Nesbett 212/825-3210 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.
