Wolfgang Miesbach: New Real-World Data Reveal Ongoing Burden in Moderate-to-Severe Haemophilia A

Wolfgang Miesbach, Professor of Medicine at Frankfurt University Hospital, shared a post on LinkedIn about a recent article by Allison Wheeler et al, published in Haemophilia Journal:

”Even with modern prophylaxis, people with moderate‑to‑severe haemophilia A continue to live with a meaningful burden of bleeding, pain and impaired quality of life.

New real‑world data in haemophilia A.

211 people with moderate‑to‑severe haemophilia A from the US

Prophylaxis with:

  • SHL FVIII in 58% of participants
  • EHL FVIII in 38% of participants
  • Emicizumab in 39% of participants

(many individuals received more than one class over time)

Longitudinal medical records plus PROMIS‑29 and pain surveys

Some observations from this study

  • Most participants still had ≥1 bleed/year, regardless of prophylaxis class – ‘low’ ABR does not equal no disease burden.
  • On‑demand factor use remained frequent, signalling persistent breakthrough bleeding.
  • Pain medication use was high across all treatment groups, reflecting substantial chronic pain and pain flares.
  • PROMIS‑29 scores showed not only pain interference, but also pronounced sleep disturbance, fatigue, anxiety and restrictions in social roles and activities – impacting work, family life and participation in daily routines.

Why this matters
These data underline that controlling bleed numbers alone is not enough.

We still need to better individualise therapy, proactively manage chronic and breakthrough pain, and systematically capture patient‑reported outcomes to understand the real physical, emotional and social burden of haemophilia A in clinical practice.

Congratulations to the Allison Wheeler and co-authors for highlighting these important unmet needs in haemophilia A.”
