Marstacimab experiences in adolescents and adults with hemophilia
Official title: Adult and Adolescent Hemophilia Patients Treated With Marstacimab: a Patient Experience Registry
Run by Institute of Hematology & Blood Diseases Hospital, China · NCT06992076 · Data updated 2026-11-12
This registry will collect experiences from adolescents and adults with hemophilia who are receiving marstacimab to see if they prefer subcutaneous injections and to track treatment burden and bleeding rates.

Is this trial a fit for you?
✓Likely a good fit
Adolescents (12 to <18) and adults (≥18) with a diagnosis of hemophilia A or B who are prescribed marstacimab for routine prophylaxis and can provide informed consent and complete follow-up are ideal candidates.
✕Probably not a fit
Patients who are pregnant or breastfeeding, planning pregnancy within two months, have severe speech/vision/memory or cognitive impairment that prevents questionnaire completion, or cannot complete at least one month of follow-up are unlikely to benefit from participation.

What this trial studies
This observational patient registry enrolls adolescents (12–17) and adults (≥18) with hemophilia A or B who are prescribed marstacimab for routine prophylaxis. Participants complete the Marstacimab-Patient Preference Questionnaire (M-PPQ) after one month to record injection-route preferences and the Hemophilia Treatment Experience Measure (Hemo-TEM) after six months to measure treatment burden. The registry will also collect clinical data, including annualized bleeding rates, to explore real-world bleeding outcomes during marstacimab prophylaxis. Data are collected at participating hospitals in China during routine clinical visits without altering prescribed care.
Why it matters
Potential benefit: If successful, the registry could show whether subcutaneous marstacimab improves patient preference and reduces treatment burden, supporting more patient-friendly prophylaxis choices.
How similar studies have gone: Previous clinical trials of marstacimab and other TFPI-targeting agents have reported reductions in bleeding, but patient-preference and treatment-burden registries for marstacimab are relatively novel.

Show full inclusion / exclusion criteria
Inclusion Criteria: \- Participants with a diagnosis of hemophilia A or hemophilia B eligible to receive prophylaxis. Clinical physicians prescribe marstacimab for routine prophylaxis treatment of hemophilia patients based on the actual conditions of the patients and in accordance with the approved indications of marstacimab. Adolescent patients(12 to less than 18 years) and adult (18 years and older) patients. Signed consent obtained before the study, participant or legally authorized representative, or participant's caregiver capable of giving signed informed consent. Exclusion Criteria: \- Those who are unable to complete at least one month follow-up based on the investigator's judgment. Severe impairment of speech, vision, memory or cognition that affects communication and ability to complete questionnaires and follow-up visits. Women of childbearing age who plan to become pregnant within the next 2 months, as well as women who are pregnant or breastfeeding. Patients are participating in other clinical trials. There are other conditions that the investigator deems unsuitable for participation in this study.
