Plain English summary of protocol
Background and study aims
Haemostats are medical devices used by surgeons to stop bleeding during procedures and also to prevent bleeding restarting after the procedure has been completed. Not all haemostats stick to the bleeding site and so are less effective at preventing post-operative bleeding. Many of the haemostats that can adhere to the bleeding site use biological or chemical agents to achieve this. This study aims to evaluate a new haemostat (TenaTac) that avoids the use of biologic or chemical agents.
Who can participate?
Patients undergoing planned surgery at one of the participating hospitals if their surgeon is part of the evaluation group
What does the study involve?
During surgery, if the surgeon needs to use a haemostat and chooses to use TenaTac, then on completion of the surgery the surgeon will complete a structured questionnaire about how well the TenaTac performed.
What are the possible benefits and risks of participating?
The benefits are that the patient will avoid exposure to the biological or chemical agents used in alternative haemostats. The risks are that the TenaTac doesn't perform as well as another haemostat.
Where is the study run from?
St John's Innovation Centre, Cambridge, UK.
When is the study starting and how long is it expected to run for?
January 2020 to December 2025.
Who is funding the study?
The co-sponsors of the study are Selentus Science (UK) and CuraMedrix (Netherlands).
Who is the main contact?
Mr Paul Hayes MD FRCS, phayes@selentus.com

| Scientific title | Real-world, post-market clinical study of the intra-procedural performance of a novel adhesive haemostat across six surgical specialities |
| Study objectives | A novel adherent haemostat using only a simple physical modification of its surface would adhere adequately to tissues, and effect haemostasis on a bleeding surgical site to the satisfaction of the operating surgeon. |
| Ethics approval(s) | Ethics approval not required |
| Ethics approval additional information | The study is a post-market clinical follow up of a CE-marked medial device being used within its Indication for Use. The choice of which haemostat to treat the patient with was at the discretion of the surgeon and no mandating of treatment occurred. No patient data was shared, only information relating to the general type of surgery and the performance of the device. |
| Health condition(s) or problem(s) studied | Treatment of haemorrhage in surgical patients |
| Intervention | A novel haemostat using only a physical modification of the device surface to affect adhesion was evaluated by multiple surgeons, across 6 surgical specialities. A structured questionnaire relating to the device performance was completed by the surgeon at the end of the procedure. The application of a haemostat to the bleeding site. No control agent is planned. The adherence of the haemostat to the tissue surface will be graded 1 to 5 by the surgeon, as will the efficacy of haemostasis obtained. |
| Intervention type | Device |
| Phase | Not Applicable |
| Drug / device / biological / vaccine name(s) | TenaTac |
| Primary outcome measure(s) |
The effectiveness of haemostasis graded from 1 (unacceptable) to 5 (excellent) by the operating surgeon at the end of the procedure. |
| Key secondary outcome measure(s) |
1. The effectiveness of adhesion graded from 1 (unacceptable) to 5 (excellent) by the operating surgeon at the end of the procedure. |
