Proven protection* from bleeds
*ALPROLIX has been proven to help patients prevent bleeding episodes using a prophylaxis regimen.
was 13.8 days.
- Your body can also make antibodies called “inhibitors” against ALPROLIX, which may stop ALPROLIX from working properly
- ALPROLIX may increase the risk of formation of abnormal blood clots in your body, especially if you have risk factors for developing clots
severe hemophilia B, ages 12-71 (factor IX activity 2% or less). Followed for up to 77 weeks, multiple characteristics of ALPROLIX were assessed, including
safety, efficacy, and pharmacokinetics:1-4
- In the once-weekly group, 63 people were given an initial dose of 50 IU/kg, which was adjusted to maintain desired factor IX levels.
- In the individualized prophylaxis group, 29 people were initially given 100 IU/kg every 10 days and their intervals were adjusted to maintain desired factor IX levels.
- In the on-demand group, 27 people infused as needed with doses ranging between 20 to 100 IU/kg depending on the severity of the bleed.
- In the surgical group, 12 people received ALPROLIX for bleed management in 14 major surgeries. 15 minor surgeries were also evaluated. Doses were adjusted
according to the type of surgery. 4 people in this group did not participate in the other groups.
