Plain English Summary
Background and study aims
We are carrying out a study of 136 patients who are scheduled for transurethral resection of the prostate (surgical procedure that involves cutting away a section of the prostate gland). During this operation, there is a high risk for bleeding. Therefore, we will test the drug Stibium D6 in order to evaluate its benefit of reduction of bleeding complications. We also test the blood clotting time in 20min intervals during the operation.
Who can participate?
We aim to recruit 136 men, age > 18 years who are scheduled for a transurethral resection of the prostate.
What does the study involve?
Patients will be randomly allocated to receive Stibium D6 intravenous (i.v.) or placebo (dummy). During the operation (under anaesthesia), four blood samples are taken at the beginning of the operation as well as after every 20min. Another blood sample will be taken 1 and 2 days after surgery, respectively. A control examination in our outpatient clinics will be 2 weeks after the operation.
What are the possible benefits and risks of participating?
There could be a direct benefit to those taking part and getting the real drug regarding bleeding complications. If the drug has a beneficial effect on blood clotting, there should be benefits to future patients undergoing transurethral resection of the prostate. Eventually, the drug could be used in surgical interventions other than transurethral resection of the prostate..
The main risk of the intervention is the extra samples of blood that has to be taken. However, the amount of blood is very small. There is no risk for iron deficiency and the related anaemia because of the blood samples. So far, there is no known risk of administering Stibium D6.
Where is the study run from?
The study has been set up by the Urology Department of the University of Bern.
When is study starting and how long is it expected to run for?
It is anticipated that recruitment will start July 2012. Participants will be enrolled on the study for a period of two years.
Who is funding the study?

Clotting disorder / intraoperative bleeding / transurethral resection of the prostate
Transurethral resection of the prostate in all patients.
50% of patients will receive placebo during this intervention, 50% will receive Stibium D6 intravenous (i.v.).
Stibium D6 -dose: 10ml of 0.000001%, Stibium D6 in 250ml 0.9% NaCl
Total duration of intervention: approximately 1 hour
Primary outcome measure
1. Complications (especially bleeding complications), bleeding complications are measured during the first 14 postoperative days (final evaluation during the final outpatient visit 14 days following surgery)
2. Blood clotting time measured at the beginning of the operation, after 20, 40 and 60 minutes of operation as well as on the 1st and 2nd postoperative day.
Secondary outcome measures
1. Intraoperaperative bleeding score measured during operation
2. Readmissions to hospital evaluated within the first 30 postoperative days
3. Duration of TURP
4. Blood glucose levels measured during operation
5. Duration of catheter in place measured within the first 2 postoperative days (during hospitalisation).
6. Time of postoperative bladder flushing required measured within the first 2 postoperative days (during hospitalisation)
