Background and study aims
Transitional cell carcinoma (TCC) of the bladder is one of the most common cancers. In 75-85% of patients the cancer is contained inside the lining of the bladder (non-muscle-invasive bladder cancer). A surgical technique called complete transurethral resection of visible tumour (TURBT) is the gold standard treatment for non-invasive bladder tumours. A single dose of chemotherapy, usually mitomycin C, is delivered directly into the bladder using a catheter (intravesical therapy) to destroy any remaining microscopic tumour and prevent the cancer from coming back. Intravesical therapy is also used in a maintenance (long term) fashion to prolong the beneficial effects of the chemotherapy. Although immediate intravesical mitomycin C or epirubicin is highly recommended, it should not be used in patients with a bladder perforation as a small number of serious complications related to mitomycin C extravasation (leakage) have been reported. The bladder lining (urothelium) prevents undesirable substances penetrating the deeper layers of the bladder wall and neutralises toxic substances. Glycosaminoglycans (GAGs) make the inner bladder wall impervious to the contents of the urine. Two key components of the layer are hyaluronic acid (HA) and chondroitin sulphate (CS). The aim of this study is to find out whether intravesical HA and CS (Ialuril®) followed by oral HA and CS plus curcumine and quercetine are safe and effective at preventing the recurrence of TCC after TURBT.

Who can participate?
Patients aged over 18 with TCC

What does the study involve?
Patients receive intravesical HA and CS (Ialuril®) immediately after TURBT, followed by oral treatment with pills (one a day for 90 days) containing CS, HA, quercitine and curcumine. TCC recurrence is assessed using ultrasound, urine tests and endoscopic assessment after 3 months.

Scientific title	Intravesical Ialuril® plus oral combination of curcumine, quercetine, hyluronic acid (HA) and chondroitin sulphate (CS) for prophylaxis of recurrent non-muscle invasive transitional cell carcinoma (TCC) of the bladder: a prospective longitudinal investigative pilot non-randomised study
Study objectives	To test the hypothesis whether or not immediate post-TURBT intravesical instillation of a combination of HA and CS (Ialuril®) repairing coating - followed by oral administration of a combination of HA and CS plus curcumine and quercetine maintaining coating - is safe, tolerated and effective in preventing the recurrence of TCC after TURBT in patients with superficial low-intermediate risk pTa-1 TCC.
Ethics approval(s)	Not provided at time of registration
Health condition(s) or problem(s) studied	Superficial (non muscle invasive) transitional cell carcinoma
Intervention	All the patients underwent standard transurethral resection of the visible lesions. Immediate post-TURBT intravesical instillation of a combination of HA and CS (Ialuril®: 50 ml/vial solution containing HA 800 mg and CS 1 mg) followed by oral treatment with pills (one a day for 90 days) containing CS 200 mg, HA 20 mg, quercitine 200 mg and curcumine 100 mg.
Intervention type	Drug
Phase	Phase I
Drug / device / biological / vaccine name(s)	Laluril®
Primary outcome measure(s)	1. Tolerability, reported as discontinuation or deviation of the protocol and safety as general or local side effects 2. Efficacy, defined as the absence of recurrence as defined by negative ultrasound evaluation, negative urine cytology and negative endoscopic assessment after 3 months
Key secondary outcome measure(s)	Morphological immunohistochemical assessment, comparing samples at entry and after 3 months for transient receptor protein vanilloids 1 (TRPV1) expression and GAGs
Completion date	31/12/2013
Reason abandoned (if study stopped)	Local ethical committees requested several changes
