(MOTIVATE)
What this study is about
This is a non-interventional, conducted at multiple hospitals, observational, international study in male persons with haemophilia A who have developed inhibitors to any replacement coagulation factor VIII (FVIII) product.
View original scientific description
This is a non-interventional, multicenter, observational, international study in male persons with haemophilia A who have developed inhibitors to any replacement coagulation factor VIII (FVIII) product. The purpose of the study is to capture different approaches in the management of persons with haemophilia A and FVIII inhibitors, document current immune tolerance induction approaches, and evaluate the efficacy and safety of immune tolerance induction, including the combination of FVIII and emicizumab. Patients will be assigned to 1 of 3 groups based on the treatments they receive, and may switch to another group if their treatment is changed. Participants will be followed after a maximum observational period of 5 years.
Interventions
BIOLOGICAL
Nuwiq
Nuwiq is a recombinant FVIII concentrate from a human cell line. It is administered via intravenous injection at a dosage determined by the investigator's discretion, in consideration of the participants' clinical condition and prescribing information.
BIOLOGICAL
Octanate
Octanate is a high-purity human Factor VIII / von Willebrand Factor (VWF) concentrate. It is administered via intravenous injection at a dosage determined by the investigator's discretion, in consideration of the participants' clinical condition and prescribing information.
BIOLOGICAL
Wilate
Wilate is a high-purity human von Willebrand Factor (VWF)/Factor VIII concentrate. It is administered via intravenous injection at a dosage determined by the investigator's discretion, in consideration of the participants' clinical condition and prescribing information.
BIOLOGICAL
Emicizumab
Emicizumab is a therapeutic antibody which brings activated factor IX and factor X together It is administered via subcutaneous injection at a dosage determined by the investigator's discretion, in consideration of the participants' clinical condition and prescribing information.
BIOLOGICAL
Recombinant factor VIIa (rFVIIa)
Recombinant factor VIIa (rFVIIa) is a blood factor VII manufactured using recombinant technology. It is administered via intravenous injection at a dosage determined by the investigator's discretion, in consideration of the participants' clinical condition and prescribing information.
BIOLOGICAL
Activated prothrombin complex concentrate (aPCC)
Activated prothrombin complex concentrate (aPCC) is an anti-inhibitor coagulant complex acting on multiple pathways to facilitate coagulation. It is administered via intravenous injection at a dosage determined by the investigator's discretion, in consideration of the participants' clinical condition and prescribing information.
Primary outcome measures
Proportion of participants achieving inhibitor titer < 0.6 Bethesda units (BU)/mL L for at least 2 consecutive measurements
Time frame: Up to 5 years
The proportion of participants in Groups 1 and 2 achieving inhibitor titer \< 0.6 Bethesda units (BU)/mL L for at least 2 consecutive measurements will be determined. FVIII inhibitor titer is measured at baseline and throughout the study, according to standard of care.
Proportion of participants achieving FVIII recovery ≥ 66% of the predefined reference value of 1.5% IU/kg body weight (Groups 1 and 2)
Time frame: Up to 5 years
The proportion of participants in Groups 1 and 2 achieving FVIII recovery ≥ 66% of the predefined reference value of 1.5% IU/kg body weight will be determined. Once inhibitor has become negative (\< 0.6 BU/mL), FVIII plasma levels are measured prior to and approximately 15 to 30 minutes after FVIII to evaluate FVIII recovery.
Proportion of participants achieving FVIII half-life ≥ 6 h (Groups 1 and 2)
Time frame: Up to 5 years
The proportion of participants in Groups 1 and 2 achieving FVIII half-life ≥ 6 h will be determined. Once inhibitor has become negative (\< 0.6 BU/mL), FVIII plasma levels are measured prior to and at 15-30 minutes and 2, 4, 8-12, and 24 hours after administration of the immune tolerance induction (or prophylactic FVIII) to evaluate half-life; when FVIII trough levels are \> 1% during regular prophylaxis, half-life can be evaluated from fewer samples or using a population pharmacokinetic model.
Annualized bleeding rate
Time frame: Up to 5 years
Annualized rate of all bleeding episodes will be reported and compared between all 3 study groups.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Male persons with haemophilia A, of any severity, who have a historical inhibitor titer ≥ 0.6 BU/mL, including those who have failed previous immune tolerance induction (ITI) attempt(s)
- Persons undergoing ITI with Nuwiq, octanate, or wilateor undergoing ITI with Nuwiq®, octanate® or wilate® and receiving prophylactic therapy with emicizumab, activated prothrombin complex concentrate (aPCC), or activated recombinant factor VII (rFVIIa)
- Participants or participants' parent(s)/legal guardian(s) must be capable of giving signed informed consent and be able to understand the trial documents
Exclusion criteria
- Participants are excluded from the trial if any coagulation disorder other than haemophilia A is diagnosed
- Partly retrospective patients will be excluded if detailed documentation on treatment, all bleeding episodes, inhibitor titers, and FVIII levels is not available for the retrospective period

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
