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.
