| Scientific title | Adjuvant urokinase in the treatment of malignant pleural effusion: The third Therapeutic Intervention in Malignant Effusion trial |
| Study acronym | TIME3-UK |
| Study hypothesis | A randomised controlled trial to evaluate whether use of intrapleural urokinase improves breathlessness and decreases the proportion of patients requiring further pleural fluid drainage to control breathlessness in subjects with septated/loculated malignant pleural effusions who are undergoing talc pleurodesis, compared to placebo. |
| Ethics approval(s) | Oxfordshire Research Ethics Committee A, 20/03/2009, ref: 09/H0604/5 |
| Condition | Malignant pleural effusions |
| Intervention | Treatment (urokinase) arm: Intra-pleural urokinase (100,000 IU in 30 ml normal saline) administered 12 hourly for a total of 3 doses. Placebo arm: Intra-pleural urokinase placebo (in 30 ml normal saline) administered 12 hourly for a total of 3 doses. All patients suitable for talc pleurodesis will receive this treatment after pleural drainage facilitated by the trial medication. For any patient where there is a contraindication to the administration of intrapleural talc, an alternative pleurodesis agent may be used. Total duration of follow-up: 12 months post-randomisation |

| Phase | Phase III |
| Drug / device / biological / vaccine name(s) | Urokinase |
| Primary outcome measure | 1. Breathlessness quantified from visual analogue scales. The primary outcome will be the change in mean daily visual analogue scale (VAS) score defining breathlessness over 28 days following randomisation. A daily VAS score will be obtained at a similar time each day to assess how breathless each patient has felt over the preceding 24 hours. The minimum clinically significant changes in the VAS scores have been established based on pilot data from previous studies determining the improvement in breathlessness associated with complete pleural fluid drainage with a permanent indwelling catheter. These are used in the power calculations. VAS methodology has been shown to be robust and reproducible. Patients who are known to be unable to record VAS scales (particularly the visually impaired) will be excluded (see Participants - exclusion criteria). Added 09/08/2016: 2. After adjuvant urokinase/placebo treatment, all patients will have a sterile 4 g talc slurry pleurodesis. Pleurodesis will be performed with talc graded to exclude majority of <10 µm particles to minimise toxicity. The hypothesis is that the urokinase treatment will improve pleural drainage such that subsequent pleurodesis is more effective. To assess whether adjuvant urokinase has improved the efficacy rate of pleurodesis, the failure rate of pleurodesis will be defined by the need for further pleural intervention within 28 days of randomisation. Recurrence of pleural fluid on imaging (e.g., chest radiograph or ultrasound) which is not causing sufficient breathlessness/pain to require further drainage will not be deemed pleurodesis failure. |
| Secondary outcome measures | 1. Radiographic improvement in the area of the pleural effusion (measured as the difference in the proportion of the ipsilateral hemithorax occupied by the pleural effusion opacity on chest radiograph) on day three (the day of pleurodesis) 2. Total volume of pleural fluid drained 3. The proportion of patients requiring a further pleural fluid drainage to control breathlessness at 3 months 4. Self reported health status ('quality of life'), quantified from standard questionnaires at each trial assessment: Chronic Respiratory Disease Questionnaire (CRDQ) and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ C-30) 5. Health care costs (from health care utilisation and cost utility analysis from EQ-5D) |
