Uracyst • 2% solution of sodium chondroitin sulfate • Medical device • Indicated for the replenishment of the GAG layer in the bladder, for patients with damaged or GAG deficient bladder epithelium • Available in 20ml vials (400mg of chondroitin sulfate per vial)

Study 1 - Nickel et al 200810 • Aim • To assess the efficacy and safety of intravesical 2% chondroitin sulfate (Uracyst) in the treatment of patients with a clinical diagnosis of IC • Method • Fifty-three patients with IC were enrolled in a multicentre, community-based, open-label study, and received intravesical instillations of Uracyst once a week for six weeks, then once a month for 16 weeks • Endpoints • The primary endpoint - the percentage of responders to treatment at week 10* * assessed by a Global Response Assessment (GRA) scale
Study 1Uracyst - Proven efficacy in the treatment of PBS/IC10

Study 2 - Nickel et al 200911 • Aim • To assess the efficacy of 6 similar weekly treatments of Uracyst (2% chondroitin sulfate) versus a placebo control. • Method • Sixty-five patients were randomised to receive either 6 once-weekly treatments of Uracyst or the intravesical placebo control. • Endpoints • The primary efficacy endpoint was the percent responders to treatment. A responder was defined as those subjects who had indicated “markedly improved” or “moderately improved”on a 7 point Global Response Assessment (GRA) scale.
Study 2Uracyst demonstrates almost twice the response rate compared to placebo11
Tolerability • Uracyst is well tolerated with no significant safety issues apparent during either efficacy study10,11 • No serious adverse events have been reportedwith clinical use • Most issues tend to arise from complications with the catheterisation process

Suggested Uracyst treatment plan • Weekly instillations for 4-6 weeks, then monthly thereafter • Optimum response within 4-6 months • Revert back to weekly treatment in cases of symptom flare-up • More frequent therapy may be required in patients with severe PBS/IC
Summary • PBS/IC patients often have a specific deficit of chondroitin sulfate on the surface of the bladder wall • Intravesical chondroitin sulfate binds extensively to the damaged bladder wall surface, helping to re-establish the GAG layer - the first-line of defence against urine • Uracyst is effective and well tolerated in the treatment of PBS/IC

Uracyst Prescribing Information The full Prescribing Information should be consulted prior to use. Uracyst®Abbreviated Prescribing Information. Description: Each ml of Uracyst contains 20mg sodium chondroitin sulfate (400mg of chondroitin sulfate per 20ml vial). Chondroitin sulfate is an acidic mucopolysaccharide and is one of the glycosaminoglycans (GAGs). The luminal surface of the bladder is coated with a layer of GAGs that provide a protective impermeable barrier to the bladder. Damage to this GAG layer may result in deficiencies to its protective barrier, inducing irritations in the bladder wall. Chondroitin sulfate is an important component of the bladder GAGs that can replenish the deficient GAG layer on the bladder epithelium. Indications: For replenishment of the glycosaminoglycan (GAG) layer in the bladder, for patients with damaged or GAG deficient bladder epithelium. Dosage and administration: Instil 20ml into the bladder after any residual urine has been removed. For optimum results, Uracyst should be used full strength without dilution, and retained in the bladder as long as possible (not less than 30 minutes). Repeat the instillation of 20ml weekly for 4 to 6 weeks, then, monthly thereafter until symptoms are relieved. Most patients benefit from 6 weekly 20ml instillations, then monthly instillations thereafter depending on their symptomatic response. Contraindications: Do not administer to patients with known hypersensitivity to the solution. Warnings: For Bladder Instillation only. Uracyst contains neither preservatives nor antimicrobials; therefore, any unused portion must be discarded. Precautions: Bring the contents of vial to room temperature before use. Adverse effects: No known adverse effects. Short-term discomfort may be caused by the catheterisation process. Legal category: Medical device. CE Number: CE 0473.
