Prospektywne badanie interwencyjne skuteczności profilaktyki Efanesoctocog Alfa Alfa na przerostu maziowym u pacjentów z hemofilią A

The objective of the study is to assess the improvement of synovial hypertrophy during the 12 months of efanesoctocog alfa prophylaxis once per week (QW) in joints with existing evidence of synovial hypertrophy in participants with hemophilia A.

The study duration for each participant is approximately 12 months.

    *An eligible joint is a joint with existing synovial hypertrophy, as defined by a HEAD-US synovitis score of 1 or 2, considering hypertrophic synovium as an indication of the presence of synovitis

  • Participant has received prophylactic treatment with hemophilia prophylaxis prescriptions in the last 12 months prior to the baseline visit (Visit 2).

Exclusion Criteria:

  • Participants are excluded from the study if any of the following criteria apply:
  • Has other associated clotting disorders at the time of consent/assent.
  • Is already under efanesoctocog alfa treatment.
  • Has a current diagnosis of an factor VIII (FVIII) inhibitor, defined as inhibitor titer ≥0.60 BU/mL.

  • Has been enrolled in a concurrent clinical interventional study or exposed to other investigational drug(s) within 3 months prior to screening for this study.
  • Is currently in an institution because of regulatory or legal order (that is, is a prisoner or a patient who is legally institutionalized).
  • Is not suitable for participation, whatever the reason, as judged by the investigator, including medical or clinical conditions, or patients potentially at risk of noncompliance to study procedures.
  • Is an employee or family member of the investigator or site personnel.
  • Is involved in a specific situation during study implementation or the course of the study that may raise ethics considerations.
  • Has hypersensitivity to efanesoctocog alfa or its components or any of its excipients that, in the opinion of the investigator, contraindicates participation in the study.

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
