Quigley QR-443 Cachexia Compound Demonstrates Dose Response Effectiveness in Second Preliminary Animal Model Study; Oral Dosing of QR-443 Equally Effective to Intra-Peritoneal Administration in Delaying the Progression of Cachexia in Preliminary Tumor Burden Mouse Model
DOYLESTOWN, Pa., January 22, 2007 /PRNewswire-FirstCall/ -- Quigley Pharma, a wholly owned subsidiary of The Quigley Corporation announced today that it has completed a preliminary follow up Cachexia study, evaluating weight loss in mice. The tumor burden Cachexia model study concluded that QR-443 was as effective in delaying the progression of Cachexia when given orally as it had been shown to be when administered intra-peritoneally in a previous study. The new data compliments the previous study results demonstrating a correlation between effectiveness and the frequency of administration of the QR-443 compound.
Cachexia is an extremely debilitating and life threatening, wasting syndrome associated with chronic diseases such as cancer, AIDs, chronic renal failure, COPD and rheumatoid arthritis, where inflammation has a significant impact and patients experience loss of weight, muscle atrophy, fatigue, weakness and decreased appetite.
The study model consisted of 4 groups of BALB/C mice being subjected to tumors resulting in Cachexia. All 4 groups (n=19) were fed 200 micro-liters phosphate buffered saline (PBS). Three groups were fed an established non-toxic 20 mg dose of the QR-443 compound at different dosing frequencies. The control group was fed (PBS) at the highest dosage frequency without QR-443. Results were determined by weighing each mouse over the course of the 27 day study. The weights of treated mice demonstrated a reduced progression of Cachexia corresponding to the frequency of dosing. Mice treated more frequently showed less weight loss and a delayed progression compared to mice treated less frequently. Untreated mice lost more weight and began losing that weight sooner than all three-treatment groups.
QR-443 has been shown in previous pre-clinical studies to inhibit the production of TNF-alpha and IFN-gamma and reduced other inflammatory cytokines associated with Cachexia.
Dr. Richard Rosenbloom, EVP/COO of Quigley Pharma, Inc. stated, "These findings in addition to previous work, show that the compound warrants continued research and development. The company will be preparing experiments to support the significance of this data with continued research."

Furthermore, no claim is made that the potential medicine discussed here is safe, effective, or approved by the Food and Drug Administration.
