VioQuest Pharmaceuticals, Inc. Exploring Strategic Alternatives For Chiral Quest, Inc. Subsidiary To Focus Resources On Drug Development; Possible Sale Of Business

BASKING RIDGE, N.J., Sept. 29 /PRNewswire-FirstCall/ -- VioQuest Pharmaceuticals, Inc., , a New Jersey-based biopharmaceutical company, announced today that it has engaged a financial advisor to assist management in considering various strategic alternatives relating to the business of its wholly-owned subsidiary, Chiral Quest, Inc., including the possible sale of that business. The Company believes that a possible sale of Chiral Quest will allow management to focus the Company's resources on its core business, the acquisition, development and commercialization of pharmaceutical compounds to treat cancer and other diseases and conditions.

Chiral Quest is an industry leader in providing its patented portfolio of chiral chemistry products and services for the pharmaceutical and fine chemical industries. It also offers contract services for catalyst screening and contract research for the development of efficient chiral manufacturing processes. Chiral Quest also provides licensing of its proprietary chiral technology and methods. Chiral Quest's significant milestones include:

* Chiral Quest reported annual sales of $669,000 in fiscal 2003, $1,485,000 in fiscal 2004 and $3,805,000 in 2005; * Chiral Quest has an active customer base of more than 60 customers, and has sold its proprietary technology and other services to 12 of the top 18 pharmaceutical companies; * Chiral Quest has signed a licensing agreement with Merck to provide its proprietary ligands and catalysts; * Chiral Quest has fully established facilities in New Jersey and China. Each facility provides process scale-up and a cost-effective access to chiral products and services in addition to various R&D manufacturing projects. In addition, this infrastructure provides an efficient contact point with selected global manufacturing partners; * Chiral Quest's intellectual property includes 12 patents with broad coverage of its proprietary technology; * Chiral Quest has commercialized 5 of its patented proprietary technology ligands and catalysts.

In the meantime, VioQuest Pharmaceuticals will continue to advance the clinical programs for its two drug candidates, VQD-002, triciribine-phosphate (TCN-P), an Akt inhibitor that targets the over expression of phosphorylated Akt which has been observed in a variety of cancers, and VQD-001, sodium stibogluconate (SSG), an inhibitor of specific protein tyrosine phosphatases (SHP-1 and SHP-2), for the treatment of solid tumors. To this end, the Company has made and continues to make significant progress with its product candidates, and has achieved several important milestones including:

* Corporate sponsored Investigational New Drug (IND) applications for each of VQD-001 and VQD-002 have been accepted by the U.S. Food and Drug Administration (FDA) in 2006; * Clinical trial enrollment is ongoing in its Phase I/IIa trial with VQD- 002, for the treatment of ovarian, breast, colorectal, and pancreatic tumors at the Moffitt Cancer Center; * Clinical trial enrollment is ongoing in its Phase I/IIa trial with VQD- 002, for the treatment of leukemia at MD Anderson; * Clinical trial enrollment is ongoing in its Phase I/IIa trial with VQD- 001 for the treatment of melanoma, renal, and other solid tumors at MD Anderson; * Clinical trial enrollment is ongoing in its investigator sponsored Phase I/IIa trial with VQD-001 for the treatment of melanoma, renal, and other solid tumors at the Cleveland Clinic Taussig Cancer Center; * The Company plans to file an NDA for VQD-001 in 2007, in conjunction with the U.S. Army, for the treatment of leishmaniasis.

Daniel Greenleaf, President and CEO, stated, "While we are continuing to advance our clinical trials, we are evaluating strategic alternatives for Chiral Quest. This strategic initiative will allow the Company to focus on its core competencies, and although we still believe in the potential of Chiral Quest to be a profitable and sustainable asset, we think that greater shareholder value will be created by directing our resources to the advancement of our clinical candidates through the regulatory process."
