Quigley Submits Investigational New Drug Application to the FDA for Its QR-333 Diabetic Peripheral Neuropathy Compound; Filing Allows Quigley to Begin Human Clinical Trials Following a 30-Day Review Period

DOYLESTOWN, Pa., March 7 (HSMN NewsFeed) -- The Quigley Corporation (Nasdaq: QGLY ) and Quigley Pharma Inc., its wholly-owned subsidiary, announced today their filing of an IND (Investigational New Drug) application with the FDA for QR-333, a topical compound for the treatment of Diabetic Peripheral Neuropathy. Today's filing allows Quigley Pharma to begin human clinical trials following a 30-day review period. If the FDA has no further comments, studies with human subjects will commence as soon as possible pending the availability of study drug.

This Application includes a compilation of all of the supporting development data and regulatory documentation required to file an IND application with the FDA. Included within the approximate 3800 page IND application are protocols for two studies including a Phase IIb human study designed to evaluate the efficacious dose range of the compound and a Phase II pharmacokinetic study evaluating safety. To this effect, a human clinical trial protocol has been filed with the Central Institutional Review Board overseeing the first IND study.

"The filing of this IND is a milestone in the drug development process as well as for Quigley Pharma," stated Dr. Richard Rosenbloom, COO of Quigley Pharma. "As we have already received FDA's comments on our IND program during Pre-IND meetings and teleconferences, we are prepared to begin these clinical trials as soon as possible."

In keeping with previous instructions given by the FDA at the Pre-IND meeting, previously announced in March 2004, the Company has completed a series of toxicity studies in animals that include the following:
    Pre-clinical             Completed in      Showed no irritation, photo

According to estimates from the American Diabetes Association, 7.0 percent of US adults or 20.8 million people have diabetes. While 6.2 million remain undiagnosed an additional 41 million Americans are estimated to have Pre-Diabetes. Longstanding diabetes increases the risk for an array of chronic health problems, and diabetic neuropathy is the most common form of peripheral nerve damage, affecting approximately 53 percent of patients who have had Type II diabetes.

QR-333 is designed and formulated to decrease oxidative stress that contributes to peripheral diabetic neuropathy and thus alleviate its symptoms. A Proof of concept study was completed in France showed that the topical compound improved the quality of life as well as improved key symptoms associated with this complication of diabetes. The subjects using the compound had 67% of their symptoms improve, suggesting efficacy. The study authors published their findings in the peer reviewed Journal of Diabetes and Its Complications.**

Quality of Life:

After four weeks of treatment, the active group substantially outperformed the placebo group in thirteen out of fourteen Quality of Life parameters.

Symptom Assessment:

Out of a total of 28 Symptom Assessment parameters, patients receiving the active formula fared substantially better than those on placebo. Certain key symptoms showed a substantially wider improvement ratio, suggesting that the active formula was particularly effective for the following symptoms:

-- Irritation of the feet due to socks or sheets.
-- Numbness of the feet
-- Tingling of the feet.
