Summary

Research Title：Adult and adolescent hemophilia patients treated with Marstacimab: a patient Experience Registry (AMBER) Protocol Number：94250855 Protocol Version Number：version 0.3 Date：15-November-2024 Leading site：Institution of Hematology \& Blood Diseases Hospital, Chinese Academy of Medical Sciences Active Pharmaceutical Ingredient：a human IgG1 monoclonal antibody that targets the tissue factor pathway inhibitor (TFPI) Drug Name Generic name: marstacimab-hncq Purpose of the Study Primary Objectives:To quantify patient preferences for subcutaneous versus intravenous (IV) injection using the Marstacimab-Patient Preference Questionnaire (M-PPQ) after 1 month of marstacimab for routine prophylaxis treatment.

To assess the treatment burden using the Hemophilia Treatment Experience Measure (Hemo-TEM) in hemophilia patients after 6 months of marstacimab for routine prophylaxis treatment.

Exploratory Objectives:

To evaluate the annualized bleeding rate (ABR) of different types of bleeds after 6 months of subcutaneous marstacimab injections in hemophilia patients.

To assess changes in joint status scores between baseline and the final visit after 6 months of subcutaneous marstacimab injections in hemophilia patients, using the Hemophilia Early Arthropathy Detection with Ultrasound in China (HEAD-US-C).

To evaluate patient preferences regarding treatment experience via M-PPQ after 6 months

DRUG

Marstacimab

the first visit (V1) is scheduled on the day of the first administration of marstacimab. The recommended dosing frequency for the patient should follow the instructions provided, which are as follows: On Day 1, administer 300 mg subcutaneously (divided into two injections, each 150 mg) (loading dose); starting from Day 8, administer 150 mg subcutaneously once a week. Record the patient's prescription recommendations, actual treatment records (administration time, dosage, frequency), and adherence rates.
