Scientific title | A randomised, double-blind validation of the significance of occult pyuria for the symptoms of the overactive bladder |
Study acronym | NOD (Nitrofurantoin in Overactive Detrusor) |
Study objectives | Study hypothesis amended as of 11/09/2007: The aim of this study is to determine whether treatment with nitrofurantoin improves total 24 hour incontinence episodes in patients presenting with symptoms of overactive bladder, who have significant numbers of inflammatory cells in their urine but a negative urine culture. Study hypothesis provided at time of registration: The aim of this study is to determine whether treatment with pivmecillinam improves total 24 hour incontinence episodes in patients presenting with symptoms of overactive bladder, who have significant numbers of inflammatory cells in their urine but a negative urine culture. |
Ethics approval(s) | Whittington and Moorfields Research Ethics Committee, 07/05/2008, ref: 08/H0721/23 |
Health condition(s) or problem(s) studied | Overactive bladder |
Intervention | Interventions amended as of 23/11/2007: Intervention group: Nitrofurantoin (Brand Name: Macrodantin®) 100 mg orally b.d (twice daily) for 6 weeks Control group: Placebo administered orally, twice daily for 6 weeks Please note that this change is due to difficulty in finding suitable placebo for the pivmecillinam preparation. Interventions provided at time of registration: Intervention group: Pivmecillinam will be administered orally at a dose of 400 mg twice daily Control group: Placebo administered orally, twice daily |

Phase | Not Applicable |
Drug / device / biological / vaccine name(s) | Nitrofurantoin |
Primary outcome measure | Number of incontinence episodes per 24 hours, assessed by bladder diary chart recorded by the patients during the intervention |
Secondary outcome measures | Secondary outcome measure amended as of 11/09/2007: 1. To determine whether treatment with nitrofurantoin improves other symptoms of over active bladder, the following will be assessed: 1.1. 24-urinary frequency 1.2. Urgency score assessed at 2 weekly intervals until the end of the trial at 6 weeks 1.3. Average voided volume assessed at 2 weekly intervals until the end of the trial at 6 weeks 1.4. Quality of life (I-Qol) assessed at 2 weekly intervals until the end of the trial at 6 weeks 2. Assessment to determine whether pus cells are eliminated from the urine, <10 WBC/uL, after long-term treatment with nitrofurantoin. This will be measured at 2 weekly intervals until the end of the trial at 6 weeks 3. Recording side effects of treatment Secondary outcome measures provided at time of registration: 1. To determine whether treatment with Pivmecillinam improves other symptoms of over active bladder, the following will be assessed: 1.1. 24-urinary frequency 1.2.
