Fibrinogen Supplementation: Fibryga vs. Cryoprecipitate
FIBRES Study: A prospective, multicenter, randomized, controlled, single-blinded study conducted in adult cardiac surgical patients experiencing clinically significant bleeding and hypofibrinogenemia.1
Primary Efficacy Outcome: Blood components (red blood cells, platelets, plasma) administered during 24 hours post bypass. A 2-sample, 1-sided test for the ratio of the mean number of units was conducted to evaluate non-inferiority (threshold for non-inferiority ratio, <1.2).1
Total Number of Allogeneic Blood Product Units Transfused Within 24 Hours After Termination of CPB
In FIBRES, fibryga demonstrated non-inferiority to cryoprecipitate
CPB=cardiopulmonary bypass; SD=standard deviation; IQR=interquartile range; ABP=allogeneic blood product; CI=confidence interval
Based on interim analysis for FIBRES study.
*Using ordinary Poisson regression, the 99.742% upper CI limit was calculated to be 1.04, below the pre-specified 1.20 non-inferiority margin, demonstrating fibryga was non-inferior to cryoprecipitate (p<0.0001, compared to the pre-specified alpha level of 0.00258)
Key Outcomes
Proven Efficacy
Fibryga was non-inferior to cryoprecipitate with regard to number of blood components transfused in a 24-hour period post bypass surgery.1
Favorable Safety Profile
Treatment-emergent adverse event (TEAE) profiles were found to be similar between fibryga and cryoprecipitate, with no significant difference observed.1
