(1) Recombinant activated factor VII (rFVIIa) is licensed in Canada for the prevention and treatment of bleeding in hemophiliacs, but it is increasingly used to control bleeding in non-hemophilic patients during surgery, or during treatment for severe trauma or intracerebral hemorrhage (ICH). (2) In one clinical trial, there was a significant reduction in mortality among patients with ICH treated with rFVIIa. In another trial, administration of rFVIIa significantly reduced the number of trauma patients needing massive blood transfusions although there was no significant difference in mortality. (3) Adequately powered randomized controlled trials are needed to clarify the efficacy and safety of rFVIIa for non-bleeding disorder indications. Phase III trials in ICH and trauma are underway. (4) There is potential for non-hemophilic use, particularly if clinical efficacy and cost effectiveness are established.
(1)重组活化凝血因子VII(rFVIIa)在加拿大被批准用于预防和治疗血友病患者的出血,但它越来越多地被用于控制非血友病患者在手术期间、严重创伤或脑出血(ICH)治疗期间的出血。(2)在一项临床试验中,接受rFVIIa治疗的ICH患者死亡率显著降低。在另一项试验中,rFVIIa的给药显著减少了需要大量输血的创伤患者数量,尽管死亡率没有显著差异。(3)需要进行足够规模的随机对照试验,以阐明rFVIIa用于非出血性疾病适应症的疗效和安全性。关于ICH和创伤的III期试验正在进行中。(4)rFVIIa存在非血友病用途的可能性,特别是如果其临床疗效和成本效益得到证实。
