Study of Recombinant Porcine Factor VIII (FVIII) in Hemophilia and Inhibitors to FVIII
United States12 participantsStarted 2005-05
Plain-language summary
The ability of a new recombinant porcine coagulation factor VIII, B-domain deleted (called "OBI-1"), to control the non-life- or limb-threatening bleeding episodes patients with hemophilia A commonly develop is being evaluated. Patients with congenital hemophilia A and a low-titer (\<20 Bethesda units \[Bu\]) inhibitory antibody to OBI-1, who meet the inclusion/exclusion criteria, will receive OBI-1 to treat their soft tissue or joint bleeding episode. At least the first two treatment episodes will be performed in the controlled setting of the hemophilia center/clinic/office, where any side effects can be observed. If the patient continues to meet the inclusion/exclusion criteria, has had no serious or severe adverse reactions to OBI-1, and has been in a home care program, the investigator may permit the patient to self-administer OBI-1 at home to treat subsequent bleeding episodes. The study will continue at least until 12 or more patients have received at least 24 treatment episodes in the aggregate.

Inclusion Criteria:
Patients must meet at least the following criteria to participate in the trial:
* Age at least 12 years.
* Clinical diagnosis of congenital hemophilia A with current inhibitor to human fVIII OR the patient is known to have developed an anti-human fVIII inhibitor antibody anamnestic response to human fVIII in the past.
* OBI-1 inhibitor antibody titer \< 20 Bethesda Units at screening.
* Uncomplicated joint or soft tissue bleed, or other non-life threatening or non-limb threatening bleeding episode.
Exclusion Criteria:
Patients will be ineligible to participate if any of the following are present:
* Current treatment plan for any acute bleeding episode incorporates the use of human fVIII (recombinant or plasma-derived).
* Presence of any life- or limb-threatening bleeding episode (defined)
* Patient has received any human fVIII or prothrombin complex concentrate (PCC), within 7 days prior to Screening, OR received any PCC within 7 days prior to treatment with OBI-1.
* Patient has received recombinant human fVIIa (rVIIa) within 3 days prior to Screening OR within 3 days prior to treatment with OBI-1.
* Significant liver disease or renal disease
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
What they're measuring
1
The percentage of successful treatment episodes, defined as having achieved control of the bleeding episode within One Loading Dose and 8 or fewer Treatment Doses, with a dose limit of 1000 U/kg in 24 hours
