CytRx Reports Promising Data from Its Open-Label Extension Clinical,Trial of Arimoclomol in ALS

LOS ANGELES--(BUSINESS WIRE)--Jun 27, 2007 - CytRx Corporation (NASDAQ:CYTR), a biopharmaceutical company engaged in the development and commercialization of human therapeutics, today announced promising data from the six-month, open-label extension of its completed Phase IIa clinical trial with arimoclomol in ALS volunteers. While the clinical trial was not placebo-controlled, arimoclomol at a 100 mg dose three times daily appeared to be safe and well-tolerated throughout the six-month period. Further, the rate of decline of several key disease symptom indicators, including the Revised ALS Functional Rating Scale (ALSFRS-R), which measures overall functional capacity, and vital capacity, which measures breathing ability, in the arimoclomol-treated group compared favorably to a matched historical control.

Several markers of disease progression were followed throughout the open-label extension clinical trial, including the ALSFRS-R, vital capacity, total body weight and body mass index (a measure of obesity). In the absence of placebo control, CytRx chose to compare the open-label clinical trial results with the placebo group of a recently-published clinical trial (Cudkowicz, M.E., et. al., Annals of Neurology 2006 volume 60:22-31) that enrolled patients with very similar characteristics. While difficult to draw definitive conclusions without a concurrent placebo control group, there was an apparent trend toward a slower decline in every disease progression marker in the arimoclomol open-label clinical trial compared with the historical placebo control. In the trial, CytRx observed a decrease in the rate of decline of 21% for ALSFRS-R, 8.0% for vital capacity, 23% for total body weight and 20% for body mass index when compared with that historical control.

Based on safety data from a previously announced rising multiple dose clinical trial, CytRx plans to commence its Phase IIb clinical trial later this y ear with a four-fold arimoclomol dose increase, subject to FDA clearance.

"We are encouraged by the favorable results of this open-label trial, which make us even more eager to proceed at an even higher dose level in further clinical testing," stated CytRx's President and CEO Steven A. Kriegsman. "The comparison of these clinical results with historical data suggests a trend toward clinical improvement. Our Phase IIb efficacy study will be placebo-controlled and is planned to include a larger number of volunteers, treated for a longer period of time with a four-fold higher dose than that used in the open-label clinical trial."

The open-label extension clinical trial was initiated in February 2006 as ALS volunteers completing CytRx's placebo-controlled, double-blind, dose-ranging Phase IIa clinical trial were provided the opportunity to receive arimoclomol treatment for up to an additional six months. A total of 69 patients were treated in the open-label arimoclomol trial for six months, while the historical control followed 99 subjects for 12 months.

In the open-label trial, arimoclomol treatment was demonstrated to be safe as indicated by the lack of clinically-significant changes in vital signs and laboratory values, compared to baseline values. Arimoclomol was also well-tolerated with a total drop-out rate of 11.6%, or an average of 1.3% per month, during the six-month trial. This compares favorably with the historical control drop-out rate of 33.3%, or an average of 2.75% per month, for the 12-month trial.

CytRx's planned Phase IIb clinical trial is currently expected to include approximately 390 ALS patients enrolled at 30 to 35 U.S. and Canadian clinical sites treated for nine months. The trial is expected to be completed approximately 18 months after enrollment begins.

About CytRx Corporation

CytRx Corporation is a biopharmaceutical research and development company engaged in the development of high-value human therap eutics. The Company owns three clinical-stage compounds based on its small molecule "molecular chaperone" co-induction technology. In September 2006, CytRx announced that arimoclomol was shown to be safe and well tolerated at all three doses tested in its Phase IIa clinical trial in patients with ALS. The Company plans to enter a Phase IIb clinical trial with arimoclomol in ALS in the second half of 2007, subject to FDA clearance. Based on preliminary discussions with the FDA, CytRx is now considering a second efficacy clinical trial for ALS, possibly in parallel with the upcoming Phase IIb trial, to provide additional efficacy data to support a possible approval decision by the FDA.

The FDA has granted Fast Track designation and Orphan Drug status to arimoclomol for the treatment of ALS, which has also been granted orphan medicinal product status for the treatment of ALS by the European Commission. The Company has announced plans to commence a Phase II clinical trial for arimoclomol in stroke recovery in the first half of 2008, subject to FDA clearance. The Company has also announced plans to commence a Phase II clinical trial with its next drug candidate, iroxanadine, for diabetic foot ulcers in the first half of 2008, subject to FDA clearance. In addition, the Company plans to open a research and development facility in San Diego in the third quarter of 2007. For more information on the Company, visit
