Review Reveals Lack of Data on Mild Hemophilia A

Key clinical point: There is a lack of evidence about bleeding rates, joint damage, quality of life, and costs of care for patients with mild hemophilia A.

Major finding: Among six studies that reported the percentage of patients with bleeding events, those numbers ranged from 5.5% (1/18) to 90.7% (68/75).

Study details: A literature review of 17 studies with data on 3,213 patients with mild hemophilia A aged 13 years or older.

Disclosures: Seven of the eight researchers reported relationships, including employment, with BioMarin. Dr. Peyvandi reported relationships with Sanofi, Grifols, Novo Nordisk, Roche, Takeda, Sobi, Bioverativ, Spark Therapeutics, Sysmex, and CSL Behring.
