ALPROLIX delivered proven bleed protection† and bleed control with median annualized spontaneous bleed rates (AsBRs) of ≤1 per year.
The recommended starting regimen is every 7 (at 50 IU/kg) or 10 (at 100 IU/kg) days with the potential to adjust to 14 days based on patient response.

*Adjustments to dose or interval were made to maintain FIX trough level 1%–3% above baseline or higher, as clinically indicated to prevent bleeding.
A total of 636 bleeding events were observed across the 3 arms of the study (fixed-interval prophylaxis, fixed-dose prophylaxis, and episodic).
Choose ALPROLIX® for personalized prophylaxis dosing
*Higher dose or more frequent dosing may be needed in patients under 12 years of age.
Offer your patients the potential to extend from 10-day dosing to a 14-day regimen, based on their response.2
ALPROLIX is believed to utilize the natural recycling pathway
of IgG1 to stay in circulation longer.3
Fc region of ALPROLIX enables it to bind to the neonatal Fc receptor, FcRn.
FcRn is part of a naturally occurring pathway that diverts ALPROLIX away
from the lysosome,
The process delays degradation, but evidence from the Phase 3 B-LONG study has shown that Fc does not accumulate. Eventually, Fc degrades naturally into amino acids.4
ALPROLIX is a recombinant clotting factor IX genetically fused to the Fc region of IgG1
ALPROLIX is made in a human cell line that allows for post-translational modifications that are comparable to endogenous factor.5

Choose ALPROLIX® for its established safety profile with low adverse reactions
|In B-LONG, previously treated patients had:||*Post-marketing experience of ALPROLIX revealed:|
|Zero inhibitors detected||
Formation of inhibitors to factor IX has been reported following administration of ALPROLIX, including in previously untreated patients.
Monitor all patients regularly for the development of inhibitors by appropriate clinical observations and laboratory tests.
|Zero vascular thrombosis events||The use of factor IX products has been associated with the development of thromboembolic complications, especially in individuals receiving continuous infusion through a central venous catheter.|
|Zero anaphylaxis||Hypersensitivity reactions have been reported with ALPROLIX. Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with factor IX replacement products.|
|Data from the Phase 3 clinical trial of 123 previously treated patients followed for up to 77 weeks who transitioned from traditional factor IX products.|
|†||Obstructive uropathy was reported in 1 subject with hematuria who developed an obstructing clot in the urinary collecting system. The event resolved with hydration and the subject continued prophylactic treatment with ALPROLIX. A causal relationship of clot formation to ALPROLIX was not established.|
ALPROLIX is contraindicated in patients who have a known history of hypersensitivity reactions, including anaphylaxis, to the product or its excipients (sucrose, mannitol, sodium chloride, L-histidine and polysorbate 20).
Hypersensitivity reactions have been reported with ALPROLIX. Allergic-type hypersensitivity reactions, including anaphylaxis, have been reported with Factor IX replacement products. The presence of inhibitors has been associated with allergic reactions with Factor IX replacement therapies, including with ALPROLIX. Evaluate patients experiencing allergic reactions for the presence of an inhibitor. Early signs of allergic reactions, which can progress to anaphylaxis, may include angioedema, chest tightness, hypotension, rash, nausea, vomiting, paresthesia, restlessness, wheezing and dyspnea. 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, including in previously untreated patients. Monitor all patients regularly for the development of inhibitors by appropriate clinical observations and laboratory tests. Evaluate patients experiencing allergic reactions for the presence of an inhibitor. Closely observe patients for signs and symptoms of acute hypersensitivity reactions, particularly during the early phases of exposure to the product. Individuals with Factor IX inhibitors may be at an increased risk of anaphylaxis upon subsequent challenge with ALPROLIX. The use of Factor IX products has been associated with the development of thromboembolic complications, especially in individuals receiving continuous infusion through a central venous catheter. ALPROLIX should be administered as bolus infusion over several minutes. The safety of ALPROLIX administration by continuous infusion has not been studied. To confirm adequate Factor IX levels have been achieved and maintained, monitor patient plasma Factor IX levels by performing a validated one-stage clotting assay. Factor IX results can be affected by the type of aPTT reagent used. Measurement with a one-stage clotting assay using a kaolin-based aPTT reagent has been shown to result in an underestimation of Factor IX levels. Monitor for the development of Factor IX inhibitors if the expected Factor IX levels in patient plasma are not attained, or if bleeding is not controlled with the recommended dose of ALPROLIX. Perform a Bethesda assay to determine if Factor IX inhibitors are present.
Common adverse reactions (incidence ≥1%) observed in clinical trials were headache, oral paresthesia, and obstructive uropathy.
Limitation of Use
ALPROLIX is not indicated for induction of immune tolerance in patients with hemophilia B.
