Understanding Treatment Outcomes and Immunologic Mechanisms in Altuviiio Immune Tolerance Induction
United States15 participantsStarted 2025-10-01
Plain-language summary
The goal of this clinical trial is to learn how well Altuviiio (efanesoctacog alpha) works for Immune Tolerance Induction (ITI) while using Hemlibra (emicizumab) to prevent bleeds.
Participants will be given Altuviiio for their ITI therapy and also be treated with Hemlibra as standard of care prophylaxis to prevent bleeding. The research doctor will decide how much and how often the participant will get Hemlibra.
Participants will need to attend visits for checkups and tests. These visits are divided into 4 periods:
1. A screening period - 1 visit up to 8 weeks before the Treatment Period starts
2. ITI Treatment Period - 1 Baseline Visit plus Interim visits that occur every 4 weeks for up to 52 weeks. (Some of the interim visits may be done via phone)
3. Tapering Period - 5 visits at weeks 2, 4, 8, 12 and 16
4. Ongoing Monitoring Period - 4 visits at weeks 20, 30, 40 and 50

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
