About Uracyst®

Interstitial Cystitis and Painful Bladder Syndrome are inflammatory diseases of the bladder wall, which cause pain, discomfort and frequent urination for those afflicted. There is no known cure for IC/PBS and currently approved products attempt to alleviate the symptoms of the disease. The quality of life for patients with IC/PBS is extremely poor, as they may need to void up to 60 times per day. Uracyst®, a sodium chondroitin sulfate solution, supplements and replenishes deficiencies in the glycosaminoglycan (GAG) lining of the bladder. The GAG lining acts as a protective barrier against irritants and toxins in the urine, and defends against bacterial adherence. Many researchers believe that more than 70% of patients with IC/PBS have deficient GAG layers allowing irritants and toxins in the urine to seep through this protective barrier causing an inflammation of the bladder wall.

Stellar currently markets Uracyst® directly in Canada and through license agreements in Denmark, Sweden, Norway, Finland, Iceland, the UK, Republic of Ireland, Netherlands, Italy, Turkey, Portugal and now Spain. Stellar also has out licensing agreements in place for Uracyst® in Israel, United States, South Korea and China, territories which are each currently awaiting regulatory approvals.
