Trial Outcomes & Findings for Efficacy and Safety of HemoStyp as an Adjunct for Management of Secondary Hemostasis in the Operative Setting (NCT NCT03654560)

NCT ID: NCT03654560

Last Updated: 2020-10-22

Results Overview

The time to hemostasis was measured from start of study treatment to the achievement of hemostasis at the target bleeding site (TBS), or to the end of the 10-minute observation period. The time to hemostasis was considered as censored at the end of the 10-minute observation period. Time to hemostasis was quantified in minutes according to its nominal time point. When re-bleeding occurred, and the cessation of bleeding is again achieved at a later time point, the effective time to hemostasis was the latter time point. The time to hemostasis was the time from start of study treatment to that last effective hemostatic time point.

HemoStyp
Subjects with an appropriate target bleeding site will have Hemostyp applied in accordance to instructions for use. HemoStyp: During elective surgical procedure (non-laparoscopic thoracic, cardiac, abdominal, or vascular surgery) subject has mild to moderate soft tissue, vascular or parenchymal bleeding present at target bleeding site after primary standard conventional surgical hemostatic methods are proven to be ineffective or impractical will have Hemostyp applied in accordance to instructions for use.
Surgicel
Subjects with an appropriate target bleeding site will have Surgicel applied in accordance to instructions for use. Surgicel: During elective surgical procedure (non-laparoscopic thoracic, cardiac, abdominal, or vascular surgery) subject has mild to moderate soft tissue, vascular or parenchymal bleeding present at target bleeding site after primary standard conventional surgical hemostatic methods are proven to be ineffective or impractical will have Surgicel applied in accordance to instructions for use.

PRIMARY outcome

Timeframe: 10 minutes

The time to hemostasis was measured from start of study treatment to the achievement of hemostasis at the target bleeding site (TBS), or to the end of the 10-minute observation period. The time to hemostasis was considered as censored at the end of the 10-minute observation period. Time to hemostasis was quantified in minutes according to its nominal time point. When re-bleeding occurred, and the cessation of bleeding is again achieved at a later time point, the effective time to hemostasis was the latter time point. The time to hemostasis was the time from start of study treatment to that last effective hemostatic time point.
