Clinical rationale Congenital factor XIII (FXIII) is a rare autosomal recessive bleeding disorder with an estimated 1 prevalence of 1 patient per 2 to 5 million people.0F The Australian Bleeding Disorders Registry (ABDR) Annual Report 2010-2011 indicates that there were 17 people in Australia with FXIII deficiency at 30 June 2011, and 7 of these individuals had received FXIII-containing product in 2 the 2010-2011 financial year.1F The Clinical Overview included an acceptable clinical rationale for the development of NovoThirteen, and much of the following information has been taken from that overview. FXIII is a pro-enzyme (pro-transglutaminase) and is the terminal enzyme in the coagulation cascade. In plasma, FXIII circulates as an inactive zymogen heterotetramer [A2B2] held together by strong non-covalent interactions. Intra-cellular FXIII is a homodimer of two A-subunits [A2] and is found in circulating platelets and monocytes. The A subunits are synthesized
