REDUCTION IN BLEEDS FOLLOWING
SWITCH FROM FIX ON-DEMAND11

A retrospective chart review across six haemophilia treatment centres in the US for patients with haemophilia B switching from previous FIX on-demand treatment to ALPROLIX prophylaxis reported:11

Numerical decrease in bleed rates11

Switching to ALPROLIX prophylaxis numerically reduced median bleed rates vs pre-switch FIX on-demand11

Median bleed rates pre- and post-switch (n=10)*11

On demand 1

Target joint outcomes11

At the end of the chart review period,
32% (17/53)
of target joints
had resolved11

Overall, 47% (n=9/19) of patients did not report a target joint11

66% (n=19/29) of patients receiving FIX on-demand prior to initiating ALPROLIX had switched to ALPROLIX prophylaxis at the end of the chart review period11

• Median (range) follow-up for all patients receiving ALPROLIX was 2.7 (0.5–5.0) years

*Included patients who had available ABR data pre- and post-switch to ALPROLIX prophylaxis.11
ABR, annualised bleeding rate; AjBR, annualised joint bleeding rate; AsBR, annualised spontaneous bleeding rate; FIX, factor IX; IQR, interquartile range; OD, on-demand.

KEY SAFETY OUTCOMES11

Specific adverse events that were collected and recorded during ALPROLIX
therapy included hypersensitivity (including anaphylaxis), nephrotic syndrome and
thrombosis/thromboembolism. Other adverse events were not collected in this review11

Reported safety outcome:

One patient experienced an AE of hypersensitivity,
which was not associated with inhibitor development11

AE, adverse event; FIX, factor IX.


REDUCTION IN BLEEDS FOLLOWING
SWITCH FROM FIX ON-DEMAND11

A multicentre, retrospective chart review was conducted across patients with
haemophilia B who had received ALPROLIX prophylaxis or on-demand
treatment for ≥6 months across six sites in the US:*11

N=64 eligible patients

Severity of haemophilia B:

  • Mild (n=9)
  • Moderate (n=17)
  • Severe (n=38)

Pre-switch regimen:

  • On-demand (n=29)
  • Prophylaxis (n=34)
  • Missing data (n=1)

Endpoints included
changes in the FIX therapy
dosing interval, factor
consumption, ABR (including
overall, spontaneous and
joint), adherance pre- and post-switch, reason
for switching and target
joint outcomes

*The primary objective was to understand the clinical characteristics and outcomes resulting from the real-world management of patients with haemophilia B being treated with ALPROLIX. The study period for retrospective data collection was 12 months prior to ALPROLIX initiation until the date of site initiation.11
ABR, annualised bleeding rate; FIX, factor IX.
