UP TO 14-day dosing with high-level protection

IDELVION keeps your factor levels high and sustained for powerful bleed protection

IDELVION delivers high factor levels with a single dose—above 5% over 14 days. With continued use, factor trough levels reach even higher—21% with prophylactic use at steady state.1,†‡

What are factor trough levels?
Steady state trough levels reflect the low point factor levels reach between doses. Having consistently high factor levels even at the lowest point between doses ensures appropriate protection.

Average FIX levels with 7-day dosing over 92 weeks in clinical trials.

Steady state is a consistent and uniform amount of factor in the body from continued use.

With a long half-life IDELVION extends time between doses

What is half-life?

Half-life measures how long it takes for the activity level of your infused factor to drop by 50%. A longer half-life means that the drug is active in your body for a longer time.

Why is a half-life of 104 hours important?

The half-life of IDELVION allows for up to 14 days between infusions in appropriate people 12 years and older.
