Congenital antithrombin deficiency

Brief summary

Incidence of the composite of TEs and TEEs in patients with congenital antithrombin deficiency under cover of Atenativ for surgical procedures or parturition to 30 days post treatment initiation.

Detailed description

• PK parameters: o Area under the curve (AUCnorm(0–∞)) o Maximum plasma concentration (Cmax) o Half-life (t1/2) o Mean residence time (MRT) o Clearance (CL) o Incremental in vivo recovery (IVR; peak concentration of antithrombin observed within the first hour after infusion) o Volume of distribution at steady state (Vss) o Time to reach Maximum Plasma Concentration (Tmax), • Efficacy Parameters: o Antithrombin activity; o Coagulation parameters (activated partial thromboplastin time [aPTT], prothrombin time [PT], international normalised ratio [INR] and fibrinogen), • Safety Parameters: o Adverse events (AEs) and serious AEs (SAEs); o Length of hospital stay; o Vital signs (including systolic and diastolic blood pressure, pulse rate, body temperature, respiration rate, results of physical examination); o Standard haematological and clinical chemistry safety variables, as well as thrombogenicity markers including D-dimer, prothrombin fragment 1 + 2 (F1+2)*, and thrombin-antithrombin complex (TAT)* * if available from local laboratories
