About VQD-002

VQD-002 (triciribine phosphate, TCN-P) is a tricyclic nucleoside that inhibits Akt, also named protein kinase B, which represents a subfamily of the serine/threonine kinase. Three members, AKT1, AKT2, and AKT3, have been identified in this subfamily and VQD-002 has been shown to inhibit all three isoforms. Akt is activated by extracellular stimuli in a phosphatidylinositol 3'-kinase (PI3k)-dependent manner. Akt is negatively regulated by PTEN tumor suppressor. Mutations in PTEN have been identified in various tumors, which lead to activation of Akt pathway. In addition, amplification, overexpression, and/or activation of Akt have been detected in a number of human malignancies, including prostate, breast, ovarian, colorectal, pancreatic, and hematologic cancers. Ectopic expression of Akt induces cell survival and malignant transformation, whereas inhibition of Akt activity stimulates apoptosis in a range of mammalian cells. Furthermore, activation of Akt has been shown to associate with tumor invasiveness and chemoresistance. These observations establish Akt as an attractive target for cancer therapy. Preclinical testing of VQD-002 has demonstrated anti-tumor activity against a wide spectrum of cancers.

About VioQuest Pharmaceuticals

VioQuest focuses on acquiring, developing, and commercializing targeted late preclinical and early clinical stage therapies with unique mechanisms of action primarily for oncology and infectious diseases. VioQuest has three targeted drug candidates in clinical development: VQD-002 which inhibits Akt, a member of the serine/threonine-specific protein kinase family that is amplified, overexpressed, and/or activated in prostate, breast, ovarian, colorectal, pancreatic, and hematologic cancers; Lenocta(TM), an inhibitor of specific protein tyrosine phosphatases SHP-1, SHP-2, and PTP1B that has demonstrated clinical and biological activity in solid tumors; and Xyfid(TM), a topical therapy which is being developed for the treatment and prevention of chemotherapy-induced Hand-Foot Syndrome (HFS). VioQuest anticipates commencing Phase II trials for VQD-002, and Xyfid in the first half of 2008. In addition, VioQuest and the U.S. Army are planning to submit a New Drug Application (NDA) to the U. S. Food and Drug Administration (FDA) in 2008 for Lenocta for the treatment of leishmaniasis.
