Refixia (nonacog beta pegol) was approved for the following therapeutic use:

Treatment and prophylaxis of bleeding in patients 12 years and above with haemophilia B (congenital factor IX deficiency).

Refixia is a purified recombinant human factor IX (rFIX) with a 40 kDa polyethylene-glycol (PEG) conjugated to the protein.

Patients with haemophilia B are deficient in coagulation factor IX, which is required for effective haemostasis. The administration of Refixia increases plasma levels of factor IX and can temporarily correct the coagulation defect in haemophilia B patients.

Factor IX is activated by factor XIa and by factor VII/tissue factor complex. Upon activation of Refixia, the activation peptide including the 40 kDa polyethylene-glycol moiety is cleaved off, leaving the native factor IX molecule. Activated factor IX, in combination with activated factor VIII, activates factor X. Activated factor X converts prothrombin into thrombin. Thrombin then converts fibrinogen into fibrin and a clot is formed.

The decision was based on quality (chemistry and manufacturing), nonclinical (pharmacology and toxicology), clinical (pharmacology, safety and efficacy) and risk management plan information submitted by the sponsor. The benefit-risk profile of Refixia was considered favourable for the therapeutic use approved.

What post-market commitments will the sponsor undertake?

The following specific conditions of registration apply to this approval:

  • Refixia (nonacog beta pegol) is to be included in the Black Triangle Scheme. The Product Information (PI) and Consumer Medicines Information (CMI) for Refixia must include the black triangle symbol and mandatory accompanying text for five years, which starts from the date that the sponsor notifies the TGA of supply of the product.
  • The Refixia (nonacog beta pegol) European Union-Risk Management Plan (EU-RMP) (version 4.0, dated 28 April 2017, data lock point 1 January 2016), with Australian Specific Annex (version 0.3, dated 2 April 2019), included with submission PM-2018-02720-1-6, and any subsequent revisions, as agreed with the TGA will be implemented in Australia.

    An obligatory component of risk management plans is routine pharmacovigilance. Routine pharmacovigilance includes the submission of periodic safety update reports (PSURs).

    Reports are to be provided in line with the current published list of EU reference dates and frequency of submission of PSURs until the period covered by such reports is not less than three years from the date of this approval letter.

    The reports are to at least meet the requirements for PSURs as described in the European Medicines Agency's Guideline on good pharmacovigilance practices (GVP) Module VII-periodic safety update report (Rev 1), Part VII.B Structures and processes. Note that submission of a PSUR does not constitute an application to vary the registration.
