Clinical trial information
Kids B-LONG was a phase 3 open-label study that investigated the safety and efficacy of ALPROLIX in 30 previously treated pediatric patients with severe hemophilia B. Fifteen patients were 1 to 5 years of age; 15 patients were 6 to 11 years of age.1

Target joint resolution with ALPROLIX
100% of adult and adolescent patients in B-YOND achieved target joint resolution by switching to ALPROLIX from a standard half-life product4
  • Target joints were resolved for 37/37 patients who had target joints at the baseline of the B-LONG trial

Clinical trial information
B-LONG was a phase 3 open-label study that investigated the safety and efficacy of ALPROLIX in 123 previously treated adult and adolescent patients aged ≥12 years with severe hemophilia B. The study included a fixed-interval (weekly) arm (n=63), a fixed-dose (interval-adjusted) arm (n=29), an episodic (on-demand) arm (n=27), and a surgical arm (n=12).1

B-YOND was an extension trial that studied the long-term safety and efficacy of ALPROLIX in 120 adult, adolescent, and pediatric patients previously treated in Kids B-LONG or B-LONG. The study included a fixed-interval arm (n=74), a fixed-dose arm (n=36), a modified prophylaxis arm (n=17), and an episodic (on-demand) arm (n=15).6

ALPROLIX is the first and only EHL factor IX with prophylaxis data for PUPs7
  • Median overall ABR: 1.24 (0-2.49)
  • Median traumatic ABR: 0.91 (0-1.8)
  • Median AsBR: 0 (0-0)
  • Median joint AsBR: 0 (0-0)

Clinical trial information
PUPs B-LONG was a phase 3 open-label study that investigated the safety and efficacy of ALPROLIX in 33 PUPs aged <18 years with moderate or severe hemophilia B
(≤2% endogenous factor IX activity). At enrollment, the median age was 0.6 years (range: 0.1-2 years).7

IMPORTANT SAFETY INFORMATION AND INDICATION

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS:

  • ALPROLIX is contraindicated in patients who have a known history of hypersensitivity reactions, including anaphylaxis, to the product or its excipients.

WARNINGS AND PRECAUTIONS:

  • Allergic-type hypersensitivity reactions, including anaphylaxis, are possible with factor replacement therapies, and have been reported with ALPROLIX. Discontinue use of ALPROLIX if hypersensitivity symptoms occur, and initiate appropriate treatment.
  • Formation of neutralizing antibodies (inhibitors) to Factor IX has been reported following administration of ALPROLIX. Patients using ALPROLIX should be monitored for the development of Factor IX inhibitors. Clotting assays (e.g., one-stage) may be used to confirm that adequate Factor IX levels have been achieved and maintained.
  • The use of Factor IX products has been associated with the development of thromboembolic complications.
  • Nephrotic syndrome has been reported following attempted immune tolerance induction in hemophilia B patients with Factor IX inhibitors and a history of allergic reactions to Factor IX. The safety and efficacy of using ALPROLIX for immune tolerance induction have not been established.

ADVERSE REACTIONS:

  • The most common adverse reactions (incidence ≥1%) in previously untreated patients were injection site erythema, hypersensitivity, and Factor IX inhibition. The most common adverse reactions (incidence ≥1%) in previously treated patients were headache, oral paresthesia, and obstructive uropathy.

INDICATION:

ALPROLIX® is a recombinant DNA derived, coagulation Factor IX concentrate indicated in adults and children with hemophilia B for:

  • On-demand treatment and control of bleeding episodes
  • Perioperative management of bleeding
  • Routine prophylaxis to reduce the frequency of bleeding episodes

Limitation of Use
ALPROLIX is not indicated for induction of immune tolerance in patients with hemophilia B.
