Clinical Trial of Factor XIII (FXIII) Concentrate

Children's Hospital of Orange County72 enrolled

Overview

Congenital deficiency of Factor XIII is a rare but potentially life threatening disorder. It is inherited in an autosomal recessive fashion. Infusion of Factor XIII has proved to be useful for prevention and treatment of bleeding episodes, especially of spontaneous intracranial bleedings. In this study, Fibrogammin P will be given to patients with congenital Factor XIII deficiency and congenital/acquired FXIII deficiency to prevent bleeding and to treat established bleeding episodes. For Factor XIII prophylaxis to prevent hemorrhages, the dosage will depend on the weight of the subject. The frequency of Factor XIII administration will be determined by the factor's circulating half-life. During the first month only, a Factor XIII pharmacokinetic study will be determined over a 4-week period. Safety data will include accrual of information on viral safety, liver function, complete blood counts and adverse events. Historical data concerning spontaneous bleeds will be collected whenever possible two years prior to treatment with Fibrogammin P.

Outcomes

Primary Outcomes

Response to Treatment of Bleeding Events Requiring Additional Factor XIII Infusions

Response is defined as: Excellent/Good = adequate hemostasis, similar to that expected for subjects without known bleeding disorders; Fair/Poor = hemostasis less than expected; None = severe bleeding, judged due to disease despite Factor XIII (FXIII) therapy. Only the subjects who needed additional FXIII infusions (apart from the prophylactic treatment) to control a bleed and who had investigator assessment of efficacy were counted in this outcome.

Time frame: Within 12 hours of FXIII infusion

Secondary Outcomes

Surgical Efficacy Assessments With Factor XIII

Surgical efficacy is defined as: Excellent/Good = adequate hemostasis, similar to that expected for subjects without known bleeding disorders; Fair/Poor = hemostasis less than expected; None = severe bleeding, judged due to disease despite Factor XIII (FXIII) therapy. Only the subjects who underwent a surgical procedure were counted in this outcome measure.

Time frame: During surgical procedure
