NCT04131036

Brief Summary

The investigators propose to study longitudinal joint and bone density changes in patients with severe Hemophilia A. Per current standard of care, most patients are on prophylactic FVIII replacement therapy intravenously several times weekly with a goal of keeping the trough \>1% FVIII. Recent phase 3 data suggest superior bleed protection with emicizumab prophylaxis every 1-2 weeks. It is the purpose of this study to longitudinally assess joint health and bone density over 3 years and to compare the effect of routine factor VIII prophylaxis with emicizumab prophylaxis.

Outcome Measures

Primary Outcomes (1)

  • joint health comparison

    Joint health changes over 3 years compared between group A (factor prophylaxis) vs. group B (emicizumab prophylaxis) as assessed by MSKUS at baseline and after 3 years.

    3 years

Secondary Outcomes (4)

  • bone density comparison

    3 years

  • comparative assessment of joint and overall health

    3 years

  • mid-point assessment of joint health and bone density

    2 years

  • biomarkers for joint and bone health

    through completion of study, average 3 years

Study Arms (2)

Arm A

Male patients with severe Hemophilia A who use prophylaxis with IV factor VIII concentrate with intended trough \>1%.

Other: assessment of joint health and bone density

Arm B

Male patients with severe Hemophilia A who use prophylaxis with SQ emicizumab.

Other: assessment of joint health and bone density

Interventions

We propose to study longitudinal joint and bone density changes in patients with severe Hemophilia A.

Sampling MethodNon-Probability Sample
Study Population

Male severe Hemophilia A patients at one of the several Hemophilia Treatment Center sites participating in this study and who meet the eligibility criteria and are interested in participating in the study.

You may qualify if:

  • Male gender
  • Severe hemophilia A (factor VIII \< 1%)
  • Age ≥ 16 year
  • Either on prophylaxis with factor VIII or emicizumab with the intention to stay on the current regimen for the next 3 years
  • Willing and able to give written informed consent/assent
  • Willing to undergo MSKUS, DEXA scan +/- collection of blood sampling for repository biomarkers
  • Willing to come in for baseline and 3 yearly visits
  • Willing to answer phone survey for bleeding and safety every 3 months

You may not qualify if:

  • Current FVIII inhibitor of \> 0.6 BU
  • Unable to take FVIII replacement
  • Other known bleeding disorder
  • Other rheumatologic disorder affecting joints
  • Other known neuromotor defect (making physical exam difficult)
