VioQuest Pharmaceuticals Receives 510(k) Response from FDA for Xyfid

BASKING RIDGE, N.J.--(BUSINESS WIRE)--September 10, 2008 -- VioQuest Pharmaceuticals (OTCBB: VOQP) today announced that it has received a determination from the U.S. Food and Drug Administration (FDA) that Xyfid (1% uracil topical) is a drug rather than a device and would be regulated with the Center for Drug Evaluation and Research (CDER) as opposed to the Center for Devices and Radiologic Health (CDRH).

"Beginning in 2008, we initiated parallel regulatory paths for two separate indications for Xyfid," said Michael D. Becker, president and chief executive officer of VioQuest Pharmaceuticals. "We considered Xyfid appropriate for review by CDRH due to our belief that the product is substantially equivalent to various predicates in that it has both the same intended use and technological characteristics as the predicates. We are disappointed by this FDA response because it will delay enabling us to offer an alternative treatment modality to physicians treating various dermatoses, which represents an area of unmet medical need. However, this decision does not reflect negatively on the ultimate approvability of the product and we are proceeding with our parallel evaluation of Xyfid for the prevention of hand-foot syndrome through CDER.”

VioQuest Pharmaceuticals submitted a 510(k) application to the FDA in July 2008 seeking marketing clearance for Xyfid as a topical skin preparation intended to improve dry skin conditions and to relieve and manage the burning and itching associated with various dermatoses including atopic dermatitis, irritant contact dermatitis, radiation dermatitis and other dry skin conditions, by maintaining a moist wound and skin environment.

VioQuest Pharmaceuticals is continuing its parallel development of Xyfid for the prevention of palmar-plantar erythrodysesthesia (PPE), also known as hand-foot syndrome (HFS). HFS is a relatively common dose-limiting side effect of cytotoxic chemotherapy, most frequently in treatment involving fluoropyrimidines, such as continuous infusion 5-fluorouracil (5-FU), and the oral 5-FU prodrug capecitabine. There are currently no treatments or preventions for HFS, which is characterized by tingling in the palms, fingers and soles of feet and by erythema, which may progress to burning pain with dryness, cracking, desquamation, ulceration and oedema. A pilot study in patients has demonstrated that topical application of Xyfid to the hands and feet may be effective in preventing the recurrence of dose limiting HFS.
