This Phase I/II randomized, controlled, multicenter study aimed to evaluate the safety and efficacy of sFilm-FS compared to Tachosil® in patients undergoing elective liver surgery requiring hemostasis at the liver surface. sFilm-FS is a new fibrin sealant patch, coating on a biodegradable tri-block polymeric film. The trial included 33 patients randomized 1:1 to receive sFilm-FS or Tachosil®. While most patients underwent liver resection, a subset underwent other hepatic surgical interventions. Safety was the primary outcome, including treatment-emergent adverse events, coagulopathies, and intraoperative blood loss. Efficacy was assessed as secondary endpoints by the time to hemostasis and hemostasis at 2, 3, 5, 7, and 10 min from product application. Hemostasis was defined as the absence of bleeding at the target bleeding site within 10 min. Both treatments were well tolerated, with no significant differences in adverse events. All patients achieved hemostasis within 10 min. The median time to hemostasis was 2 min for sFilm-FS and 3 min for Tachosil®. sFilm-FS is a promising, well tolerated, fibrin sealant patch, offering the potential for a superior Fibrin Sealant patch that could improve surgical outcomes. Further studies are recommended to validate these findings in larger populations.
