Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1) Annual bleeding rates (ABR): To determine the frequency of all documented bleeding episodes experienced by participants after switching to efanesoctocog alfa, providing a quantitative measure of the treatment's efficacy in bleeding control. 2) Joint health assessed via ultrasound: To conduct a detailed evaluation of joint health using ultrasound and the Haemophilia Early Arthropathy Detection with Ultrasound (HEAD-US) protocol with the focus on inflammatory synovial changes. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1) Annual traumatic, spontaneous and joint bleeding rates 2) Number of Annual bleeding rates of zero 3) Factor substitution amount and frequency: To determine dosage and frequency of efanesoctocog alfa administration 4) Clinical Joint health: To evaluate the patients’ joint health using the Haemophilia Joint Health Score (HJHS) and the total HEAD-US score 5) Pain status using the numeric rating scale (NRS) 6) Semi-objective pain status assesed trough pain pressure thresholds at the most affected haemophilic joints. 7) Measurement of grip strength 8) Muscle stiffness of the M. rectus femoris assesd with myotonometry 9) Muscle thickness of the M. rectus femoris assesed with ultraound 10) Functional mobility and balance are evaluated with the Timed Up and Go (TUG) Test and the single leg stand test in single and dual tasking conditions 11) Questionnaires and surveys are used to evaluate the patients’ subjective functional, pain, and disease specific states: PROMIS Questionnaire, German Pain Questionnaire, Haemo-QoL, HEP-Test-Questionnaire, Haemophilia Activities List, Veritas-Pro Questionnaire, and semi-structured questions | — |
