CytRx Corporation (CYTR) Adds Three Oral Clinical Stage Drug Candidates With Acquisition Of Assets Of Biorex Research & Development Company And Closes Related Financing

10/19/2005 5:11:45 PM

LOS ANGELES, Oct. 5 /PRNewswire-FirstCall/ -- CytRx Corporation has acquired all the clinical and pharmaceutical assets and related intellectual property of Hungary-based Biorex Research & Development RT. ("Biorex"), a privately held biotechnology company focused on the development of novel small molecules with broad therapeutic applications in neurology, diabetes, and cardiology. This acquisition dramatically accelerates CytRx's entry into clinical testing for amyotrophic lateral sclerosis (ALS; Lou Gehrig's Disease), with an anticipated initiation of a Phase II clinical trial for the drug arimoclomol during the second quarter of 2005. The acquisition of Biorex's assets also provides CytRx with a pipeline of at least two additional oral drug candidates at various stages of clinical development up to Phase II, a library of 500 small molecule drug candidates and an extensive intellectual property portfolio. In connection with the acquisition, CytRx paid a cash purchase price of US $3,000,000 and agreed to make milestone payments upon the occurrence of certain regulatory filings and approvals related to the acquired products.

Steven A. Kriegsman, CytRx's President and CEO, discussed the company's rationale for the transaction, "In the past several months, CytRx has refined its business strategy to focus on the development of therapeutics for ALS, obesity/type 2 diabetes, HIV and CMV. This acquisition significantly expands and accelerates our efforts in ALS by providing us with arimoclomol, a clinical-stage ALS drug with substantial revenue potential. We believe we can reach clinical proof-of-principle quickly with arimoclomol, since the drug has already demonstrated therapeutic efficacy in a pre-clinical model of ALS and was well absorbed and well tolerated in Phase I clinical trials. Due to the severity of ALS and the current lack of an effective treatment, we expect that arimoclomol will receive orphan drug status with the FDA. Therefore, a Phase II trial demonstrating efficacy could be sufficient to support registration for marketing. Additionally, the opportunity to obtain three small molecules in one transaction, each of which has substantial human safety data and therapeutic potential, further strengthens our product pipeline to complement our ongoing work in the development of RNAi therapeutics."

Dr. Robert H. Brown, Jr., Professor of Neurology at Harvard Medical School, founder of the Cecil B. Day Laboratory for Neuromuscular Research at Massachusetts General Hospital, and a recognized authority on ALS and member of CytRx's Scientific Advisory Board said, "The preliminary data makes arimoclomol an extremely important ALS drug candidate because of its demonstrated safety profile and the potential to treat both sporadic (spontaneous) and familial (inherited) forms of ALS."

Portfolio of Three Acquired Drug Candidates:

Biorex's small molecule drugs provide cellular protection from abnormal proteins by activating molecular "chaperone" proteins that can repair or degrade the damaged proteins that are believed to cause many diseases, including ALS.

Arimoclomol (ALS, Lou Gehrig's Disease)

Originally developed to treat diabetic complications, arimoclomol was recently discovered to significantly inhibit progression of ALS in an experimental animal model of the disease (Kierin et al., Nature Medicine, April 2004, Vol. 10(4), 402-5).

"The mechanism of these drugs accomplishes the same goal as RNAi, removal of toxic proteins, but does it at the protein level instead of at the RNA level," said Jack Barber, Ph.D., CytRx Senior Vice President of Drug Development.

The company's RNAi approach seeks to prevent the production of a toxic protein that causes disease in a subset of ALS patients that have inherited a mutation in the superoxide dismutase 1 (SOD1) gene. CytRx believes that arimoclomol would not only target the SOD1 protein, but also additional toxic proteins that may be involved in the more common ("sporadic") form of ALS as well. Arimoclomol would thus dramatically increase the number of treatable ALS patients, compared with the RNAi approach. "We plan to continue development of our RNAi approach to ALS concurrently with developing arimoclomol, but if both drugs prove to be effective, we would focus any immediate clinical development activities on the orally available arimoclomol, since it addresses a broader patient population," said Dr. Barber.

Iroxanadine (Diabetes and Cardiovascular Disease)

Iroxanadine has been tested in two Phase I clinical trials and one Phase II clinical trial where it was well tolerated and showed signs of efficacy, significantly improving the function of endothelial cells in blood vessels of patients at risk of cardiovascular disease. CytRx intends to initially develop the drug to improve endothelial dysfunction in indications with what it believes will be clinical end-points that can be demonstrated relatively quickly, such as diabetic wound healing. The company hopes to demonstrate efficacy in these smaller market indications to build value as part of a strategy to potentially out-license iroxanadine to one or larger pharmaceutical companies for the major market cardiovascular indications.

Dr. Louis Ignarro, Noble Laureate, CytRx's Chief Scientific Spokesman and world authority in cardiovascular disease noted, "The safety and efficacy data from two Phase I clinical trials and one Phase II trial are extraordinary and provide CytRx with a clear roadmap to quickly bring iroxanadine to market to address endothelial dysfunction, a common complication associated with diabetes."


Bimoclomol is a drug that has been shown to be safe in two large Phase II clinical trials. Although the drug did not show efficacy for diabetic neuropathy, the indication for which it was tested, CytRx believes this compound could be effective for other therapeutic indications.

Details of the Transaction and Financing

In conjunction with this acquisition, CytRx completed a private placement of 4,000,000 shares of its common stock to institutional investors, with gross proceeds of $4 million. The company also issued warrants to purchase an additional 2,800,000 shares of common stock exercisable at an exercise price of $1.72 per share for a period of five years. CytRx has agreed to register all of the privately placed shares of common stock, together with the shares issuable upon exercise of the warrants, for resale.

The offering proceeds were used to acquire the assets of Biorex. Rodman & Renshaw served as the lead placement agent in the financing. Rodman & Renshaw also served as financial advisor to CytRx Corporation on the acquisition.
