Study information
| Study design | This is a phase II, multicentre, randomised, double-blind, placebo-controlled, parallel group, pilot study. |

| Scientific title | |
| Study acronym | PSD597 Bladder Biopsy |
| Study objectives | Cystoscopies are often performed in the physician office using local anaesthesia in the form of 2% lidocaine gel which is squeezed through the urethra prior to insertion of the cystoscope. This results in anaesthesia of the urethra allowing passage of the cystoscope to be generally well tolerated. However, additional procedures beyond a visual diagnosis may not be possible as the local anaesthetic effect is limited to the urethra. Patients who are able to tolerate it do have bladder biopsies performed without anaesthesia but this procedure, though bearable, is painful. If a technique was available that allowed the anaesthetic effect to be extended beyond the urethral mucosa to the bladder mucosa and sub-mucosal space, it would be possible to carry out many more procedures in the office with a resulting reduction in cost and an increase in convenience and comfort to the patient. |

| Intervention | This is a phase II, multicentre, randomised, double-blind, placebo-controlled, parallel group, pilot study to determine proof of efficacy, safety, tolerability and pharmacokinetics of intravesical PSD597 in reducing the pain of bladder biopsy in the conscious patient receiving no sedation or other analgesia or anaesthesia except urethral anaesthesia with 2% lidocaine gel. 1. A single dose of PSD597 or placebo will be instilled via urinary catheter and remain in the bladder for 15 minutes before being drained through the cystocope sheath. PSD597 consists of 200 mg lidocaine (as 5ml of 4% lidocaine) instilled into an empty bladder via a urinary catheter followed by 5 ml 8.4% sodium bicarbonate solution. 2. Placebo consists of 10 ml normal saline instilled as two 5 ml instillates via a urinary catheter. Standard treatment if discontinued from study. |

| Pharmaceutical study type(s) | |
| Phase | Phase II |
| Drug / device / biological / vaccine name(s) | PSD597 (consists of 200 mg lidocaine as 5ml of 4% lidocaine) |
| Primary outcome measure | To assess the change in bladder pain between baseline and immediately after the first bladder biopsy achieved by PSD597 versus placebo. |
| Secondary outcome measures | 1. To assess the change in bladder pain between baseline and different aspects of the procedure following treatment with PSD597 versus placebo. 2. To assess the safety and tolerability of PSD597 dosed intravesically prior to bladder biopsy. 3. To measure systemic exposure to lidocaine following intravesical PSD597 in patients undergoing bladder biopsy. |
