Despite the increasing availability of gene sequencing, several barriers prevent it from having utility as a tool for diagnosis of type 1 von Willebrand disease.
For a cutoff von Willebrand factor antigen value of 100 IU/dL above which repeat testing was not necessary, negative predictive value was 96.6%.
Patients treated with bypassing therapy experienced significantly higher medical and outpatient pharmacy costs.
Researchers have found that the estimated number of men with hemophilia is higher than known diagnoses, prompting a call for improved diagnosis approaches.
The Food and Drug Administration (FDA) has granted Orphan Drug designation to SIG-001 (Sigilon Therapeutics) for the treatment of hemophilia A. SIG-001 utilizes Sigilon’s Shielded Living Therapeutics platform to implant engineered human cells to produce stable blood plasma levels of factor VIII. The cells are also shielded by Sigilon’s proprietary Afibromer biomaterials matrix that minimizes…
