LONDON, ONTARIO--(Marketwire - 06/23/10) - Stellar Pharmaceuticals Inc. (OTC.BB:SLXCF - News) ("Stellar" or "the Company"), a Canadian pharmaceutical developer and marketer of high quality, cost-effective products for select health care markets, today announced that it has received a Notice of Allowance from the U.S. Patent and Trademark Office (USPTO) for intellectual property central to one of the Company's lead products, Uracyst® (a sterile sodium chondroitin sulfate solution, 2%), which is useful in the treatment of interstitial cystitis/painful bladder syndrome ("IC/PBS").
Stellar's patent application, entitled "Cystitis Treatment with High Dose Chondroitin Sulfate," describes the treatment of IC/PBS by instillation of an optimized dose of chondroitin sulfate. Upon Stellar completing the final formalities, including the payment of applicable fees, the Company expects this patent to issue. Once issued, the patent will expire in 2024.
Peter Riehl, Stellar's President and Chief Executive Officer, commented, "With Uracyst® patents already issued in USA, Canada, China, and Australia, and with numerous additional international patents pending, the USA patent expands Stellar's already formidable intellectual property estate. Issuance of this patent also triggers a milestone payment of US$1,300,000 from our USA based marketing and distribution partner, Watson Pharma, Inc. We are very excited about the future potential of Uracyst® in this important market, which is currently in clinical development in the USA. This Notice of Allowance further validates the innovative nature of Stellar's approach to the treatment of interstitial cystitis/painful bladder syndrome, and underscores our Company's leadership in this field."
About Uracyst®
It is believed that over 70% of IC/PBS patients have defects in their bladder glycosaminoglycan layers. The glycosaminoglycan ("GAG") layer is a mucosal lining of the bladder that acts as a protective barrier against irritants and toxins in the urine and defends against bacterial adherence. When the GAG layer is damaged, these irritants and toxins in the urine seep through, causing an irritation to the bladder wall. This results in increased frequency and urgency to void (up to 60 times a day). Many IC/PBS patients also experience severe pelvic pain. These symptoms can be debilitating and have a serious impact on a patient's quality of life.
Chondroitin sulfate (ChS) is believed to be the major GAG component responsible for the barrier function. Uracyst® was developed to replenish this defect in IC/PBS patients.
Uracyst® 2% (400 mg) ChS dose has been shown to be the ideal dosage to saturate the bladder, thus restoring the barrier function. Instilled fluid volume of Uracyst® 20 mL also allows patients to retain the treatment in the bladder for a longer period of time, enabling a better uptake of the delivered dosage and a faster onset of symptomatic relief. Uracyst® is also one of the most cost effective treatments for these patients. Combine treatment efficacy with the most cost effective therapy and it becomes understandable why Uracyst® is becoming the product of choice in treating IC/PBS.
