Zipliner—Your doctor will choose the prophylaxis treatment that is right for based on your clinical condition and response


Your doctor will choose the regimen that's right for you based on your clinical condition and response. Adolescents and adults start on 7-day dosing, and then once well-controlled, may work with a doctor to explore extended dosing.*

7 day dosing
14 day dosing

Well‑controlled? 14-day dosing may be right for you.

Greater freedom from infusions with dosing flexibility

104-hour single-dose half-life means extended bleed protection. You can stay at 7-day or, if you're well controlled, infuse less often—IDELVION is the only FDA-approved FIX for 14-day dosing. Choose the frequency of dosing with your doctor that works best with the lifestyle you want.

*Once well-controlled (1 month without spontaneous bleeding or requiring dose adjustments on a weekly dose of ≤40 IU/kg), people 12 years and older can be transitioned to 14-day dosing.

Based on a single dose of IDELVION at 50 IU/kg in adults (≤18 years).


On-demand dosing to meet your needs

IDELVION is indicated for on-demand treatment of minor, moderate, and major bleeds. Work with your doctor to find the dose that’s best for you.

Ray on transitioning from
on-demand to prophylaxis

Before, I couldn’t see sticking myself two to three times a week. Extended dosing lets me work with my doctor to develop a care plan that works for me.”
