Brief summary
Phase 1 Single-Arm Study Evaluating ClotFoam as an Adjunct to Hemostasis in Abdominal Surgery in Which Liver Bleeding is Encountered.
Detailed description
In any open surgery bleeding usually occurs. Surgeons try to stop the bleeding by using his/her usual surgical practice. These include, but are not limited to: suturing (stitches), ligation (tying up) or cautery (to burn in order to stop or prevent bleeding). It is often necessary for surgeons to use an additional treatment to stop the bleeding. This may include the use of a hemostatic product (used to stop bleeding). This Phase I study consists of a single arm evaluating the safety of ClotFoam as an adjunct to hemostasis. ClotFoam® is an investigational product-a gelatin-based hydrogel carrying a fibrin monomer-that has been designed for supportive treatment in general surgery for the improvement of hemostasis, where standard techniques are insufficient. The evaluation will be conducted in 24 patients who are scheduled to undergo elective open surgery in which liver bleeding is encountered requiring control of mild-to- moderate bleeding where standard surgical techniques are expected to be ineffective and/or impractical. All subjects who meet eligibility criteria and who provide informed consent to participate will be assigned to ClotFoam topical treatment. Subjects who will be screened for eligibility to participate in this study will be those who are scheduled to with undergo an elective (non-emergency) hepatic wedge resection or anatomic resection (of 1 to 5 contiguous hepatic segments or a surgical procedure in which liver bleeding is encountered such as removal of the gall bladder (open), bile duct excision wherein an appropriate target bleeding site is identified. Subjects undergoing living-related liver donation are also eligible. Participants will have post-operative follow ups at day 1,2,5, and 10 post-procedure, 2 weeks post procedure, and 12 weeks post-procedure. The follow up visits will consist of safety evaluations (physical exam, adverse event assessment, laboratory evaluations).
