Safety, Pharmacokinetics and Efficacy of an ATIII Concentrate
brief summary
To assess the safety, pharmacokinetics and efficacy of a plasma-derived AT-III concentrate in the treatment of subjects with congenital AT-III deficiency.
detailed description
This study will be a prospective, unblinded, non-randomized, open-label, multi-center Phase II/III study with 2 segments, i.e. a PK evaluation (Segment I), and an assessment of prophylaxis in surgical interventions and pregnancy/delivery, (Segment II). During the PK segment (Segment I), the subjects would remain on their current anticoagulation therapy except for subjects on heparin therapy where a wash-out period of at least 5 half-lives would be required. In total, 15 subjects with congenital ATIII Deficiency will be enrolled for the PK assessment (Segment I).
For Segment II, fifteen episodes will be treated. Recruitment of individual subjects with high risk for venous thrombosis for Segment II of this study is necessary because of the rarity of Antithrombin deficiency in the population.
