PROVEN BLEED PROTECTION
IN A COUNTRY-WIDE SWITCH7
In a four-year retrospective study (two years pre-switch and two years
post-switch),
all patients with haemophilia B in Ireland (N=28) were
switched from SHL FIX* to
ALPROLIX prophylaxis, reporting:7
Improved ABRs7
ABRs improved with ALPROLIX vs pre-switch FIX7
Pre- and post-switch median ABR (N=28)†7

More patients with zero bleeds7
14%
numerical increase in patients
experiencing zero bleeds
12–24 months after switching from SHL FIX 18% (5/28) vs. 4% (1/28)7
p-values not reported
Reduced factor consumption7
28% reduction in weekly (median) factor consumption with
ALPROLIX7
Pre- and post-switch factor consumption (N=21)7

Reduced injection frequency7
Most patients halved the number of injections
per year with ALPROLIX
52 vs
104
injections¶7
No safety data were collected.

*Includes patients previously treated with on-demand (n=6) and prophylactic SHL FIX (n=22) at the point of switchover.7 †0–12 months after initiation of ALPROLIX prophylaxis.7 ‡Median change between pre- and post-switch ABR.7 §Median change between pre- and post-switch factor consumption.7 ¶Calculated from dosing schedules pre- and post-switch. Most patients on prophylaxis with SHL FIX were on twice-weekly injections (n=19/22).7
ABR, annualised bleeding rate; FIX, factor IX; IU, international unit; SHL, standard half-life.
Improvements in activity-related pain8
After switching to ALPROLIX patients reported:
33%
reduction in interference of activities
due to chronic pain (p<0.001)8
25%
reduction in the number of activities during
which chronic pain occurred
(p<0.001)8
compared to pre-switch treatments.

*As part of a national tender process.7 †Two patients were treated episodically and with prophylaxis for differing time periods in the two years prior to switchover.7
FIX, factor IX; SHL, standard half-life.
