A Study Investigating Coagadex in the Treatment AFXD Associated With AL Amyloidosis
brief summary
The purpose of this study is to evaluate the efficacy and safety of Coagadex in treating active bleeds and to manage peri-operative bleeding in participants with acquired factor X deficiency associated with AL amyloidosis.
detailed description
This study is designed to evaluate the efficacy and safety of Coagadex® in treating active bleeds and to manage peri-operative bleeding in participants with aFXD associated with AL amyloidosis. Coagadex® is a plasma-derived human coagulation factor concentrate expected to treat bleeding episodes in patients with aFXD associated with AL amyloidosis by delivering concentrated Factor X to address the clotting deficiency caused by the disease.
aFXD is a rare condition (prevalence of \<1 / 1 000 000 \[Orphanet 2024\]) and may occur due to infections, neoplastic and chronic diseases (Lee G et al., 2012). aFXD is considered severe when the FX coagulant activity (FX:C) level is \< 25% of normal (normal range 70 - 150 IU/dL), and moderate when FX:C level is 25% to 50% of normal (Choufani et al., 2001).
AL amyloidosis is the most common cause of acquired FX Deficiency (aFXD). In AL amyloidosis, amyloid fibrils bind to and reduce the levels of circulating FX and shorten its half-life, causing aFXD, leading to an increase in risk of bleeding. Bleeding may occur both in patients with moderate and severe deficiency
