This was a prospective, randomized, double-blind, controlled, Phase II study to evaluate the safety and efficacy of Topical Thrombin (Human) Grifols as an adjunct to hemostasis during vascular (IG1202-A), hepatic (IG1202-B), soft tissue (IG1202-C), and spinal (IG1202-D) surgical procedures. Approximately 180 subjects were randomized into 1 of 2 treatment groups in a 2:1 ratio: Topical Thrombin (Human) Grifols (120 subjects) or Bovine Thrombin JMI (60 subjects) among the 4 types of surgeries. Randomized subjects were evaluated for identification of a target bleeding site (TBS) in which control of bleeding by conventional surgical techniques (including suture, ligature and cautery) was ineffective or impractical and required an adjunct treatment to achieve hemostasis. The Investigator rated the intensity of bleeding at the TBS. Topical Thrombin (Human) Grifols or Bovine Thrombin JMI was applied to the TBS and the time to hemostasis was assessed at various timepoints during a 5-minute observation period.~Subjects were evaluated by surgery type and by integrated analysis of clinical studies IG1202-A, IG1202-B, IG1202-C, and IG1202-D.
This purpose of this clinical trial was to study the safety and efficacy of Topical Thrombin (Human) Grifols as an add-on treatment to help stop bleeding during vascular, liver, soft tissue, and spinal surgical procedures.
