AUC(0-14days) was calculated by a combination of linear and logarithmic trapezoidal methods and expressed in the unit of concentration × time. The linear trapezoidal method used for all incremental trapezoids arising from increasing concentrations and the logarithmic trapezoidal method used for those arising from decreasing concentrations. Plasma fibrinogen activity determined by the Clauss method in the central laboratory of the study. Pharmacokinetic (PK) parameters adjusted for baseline fibrinogen level calculated by deducting the pre-infusion fibrinogen concentration from the post-infusion concentrations before the calculation.

Incremental IVR was calculated for fibrinogen levels from the peak level recorded within and included the first four hours after the end of infusion and reported as milligram per deciliter per milligram per kilogram \[mg/dL\]/\[mg/kg\]. IVR was determined for every participants using the following formula: (\[FIB max (mg/dL)\] - \[FIB pre-infusion (mg/dL)\])/FIB administered (mg)/Body weight (kg), where the FIB max is the peak FIB activity within the first four hours after the end of infusion and FIB pre-infusion was the baseline FIB activity level of the participant. FIB administered was the actual administered dose calculated using the actual volume administered to the participant, the declared potency, and the true concentration of FIB in the batch used.

MCF was as a functional parameter of blood's ability to coagulate, provides an indirect measure of hemostatic efficacy of replacement treatment with fibrinogen concentrates in participants with fibrinogen deficiency. Rotational thromboelastography (ROTEM) was performed on frozen plasma samples by the central laboratory to measure MCF. Undetectable MCF values were set to 0.
