         CYTRX CORPORATION REPORTS FIRST QUARTER 2004 FINANCIAL RESULTS

LOS ANGELES, CA - MAY 17, 2004 - CytRx Corporation (Nasdaq: CYTRE) today
announced its financial results for the three-month period ended March 31, 2004.
For the quarter, the Company reported a net loss of $3,774,000, or $0.11 per
share, versus a net loss of $914,000, or $0.04 per share, for the comparable
quarter of 2003.



The primary items affecting comparability between the first quarter of 2004
versus the first quarter of 2003 were an increase in general and administrative
costs, reflecting primarily an increase in the scope of the company's
operations, and an increase in research and development costs. The majority of
the research and development costs were associated with the implementation of
the company's RNAi based research and development programs.


Cash and short-term investments totaled $10,005,000 and the Company had working
capital of $9,246,000 at March 31, 2004. This compares with cash and short-term
investments of $11,644,000 as of December 31, 2003 and working capital of
$10,761,000. More detailed financial information is available in the Company's
Form 10-




Q for the quarter ended March 31, 2004,  which was filed with the Securities and
Exchange Commission on May 17, 2004.


Steven A. Kriegsman, CytRx's President & CEO, commented, "We are very pleased
with our progress during the fourth quarter. We have added several prominent
scientists to our advisory team which will strengthen our research efforts. We
continue to move forward in our drug discovery and pre-clinical efforts for ALS,
obesity and type 2 diabetes."



     Highlights of the first quarter of 2004 include:



     -    The company, Advanced Bioscience Laboratories (ABL) and the University
          of Massachusetts Medical School (UMMS) announced that ABL had filed an
          Investigational New Drug Application (IND) with the Food and Drug
          Administration (FDA) for a Phase I clinical trial for a new HIV
          vaccine formulation. The IND was accepted by the FDA in March 2004,
          with volunteers beginning to enroll in the trial in April 2004. The
          company will have the right to acquire this vaccine product following
          completion of the Phase I trial.

     -    Craig C. Mello, Ph.D., a Blais University Chair and Distinguished
          Professor of Molecular Medicine at UMMS, and a co-discoverer of RNAi,
          joined the Scientific Advisory Boards of the company and its
          subsidiary.

     -    Tariq Rana, Ph.D., the founding Director of the Program in Chemical
          Biology and Professor of Biochemistry & Molecular Pharmacology at UMMS
          and a prominent biomedical advisor, has joined the Scientific Advisory
          Boards of the company and its subsidiary.

     -    The company's subsidiary, CytRx Laboratories, located in Worcester,
          Massachusetts, initiated its drug discovery program to identify,
          screen and validate novel targets for the treatment of diabetes and
          obesity and then discover new chemical entities (NCEs) to address
          these targets. This subsidiary, with 14 full-time scientific and
          support personnel, is combining integrated metabolic




          diseases biology with its proprietary high throughput chemistry
          platform to develop molecular based medicines to treat diabetes and
          obesity.

     -    The company earned a $100,000 milestone payment due from Vical
          Incorporated (Nasdaq: VICL - News) pursuant to Vical's license of
          CytRx's TranzFect technology. CytRx's TranzFect technology is
          incorporated in a plasmid DNA vaccine for cytomegalovirus (CMV), being
          developed by Vical, for which Vical initiated a Phase I clinical
          trial.
