Ajovy (fremanezumab) was approved for the following therapeutic use:

Ajovy is indicated for the preventive treatment of migraine in adults.

Fremanezumab is a fully humanised IgG2Δa/kappa monoclonal antibody produced by recombinant DNA technology that is derived from a murine precursor. Fremanezumab potently and selectively binds the calcitonin gene-related peptide (CGRP) ligand and blocks both CGRP isoforms (α-and β-CGRP) from binding to the CGRP receptor preventing the activation of the trigeminal system. While the precise mechanism of action by which fremanezumab prevents migraine attacks is unknown, it is believed that prevention of migraine is obtained by its effect modulating the trigeminal system.

Fremanezumab is highly specific for CGRP and does not bind to closely related family members (for example, amylin, calcitonin, intermedin and adrenomedullin).

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 Ajovy 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:

  • Ajovy (Fremanezumab) is to be included in the Black Triangle Scheme. The PI and CMI and any other agreed additional risk minimisation materials for Ajovy 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 Ajovy (Fremanezumab) EU-Risk Management Plan (RMP) (version 1.4, dated 29 January 2019, data lock point 29 January), with Australian Specific Annex (version 1.1, dated 16 April 2018), included with submission PM-2018-03494-1-1, 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.

  • Ajovy is a new biological entity, and as such meets the inclusion criteria for the Black Triangle Scheme. The relevant warning symbol and statements are included in the supplied PI, CMI and Instructions for Use leaflet. All these risk minimisation materials will be included as a package insert in the primary carton.

    Patients eligible for self-administration will be trained by their doctor or nurse per the agreed PI. The CMI and “Instructions for Use” guide warns patients of self-administration without training. Together with the pre-filled syringe, the outpatient is to have access to an injection training video.

    PI, CMI and IFU must be included as package insert.

  • It is a condition of registration that all batches of Ajovy (fremanezumab) imported into/manufactured in Australia must comply with the product details and specifications approved during evaluation and detailed in the Certified Product Details (CPD).
  • It is a condition of registration that each batch of Ajovy (fremanezumab) imported into/manufactured in Australia is not released for sale until samples and/or the manufacturer’s release data have been assessed and endorsed for release by the TGA Laboratories Branch. Outcomes of laboratory testing are published biannually in the TGA Database of Laboratory Testing Results.

    The sponsor should be prepared to provide product samples, reference materials and documentary evidence as defined by the TGA Laboratories branch. The sponsor must contact Biochemistry.Testing@health.gov.au for specific material requirements related to the batch release testing/assessment of the product. More information on TGA testing of biological medicines is available at Testing of biological medicines.

    This batch release condition will be reviewed and may be modified on the basis of actual batch quality and consistency. This condition remains in place until you are notified in writing of any variation.

  • Certified Product Details

    The Certified Product Details (CPD), as described in Guidance 7: Certified Product Details of the Australian Regulatory Guidelines for Prescription Medicines (ARGPM), in PDF format, for the above products should be provided upon registration of these therapeutic goods. In addition, an updated CPD should be provided when changes to finished product specifications and test methods are approved in a Category 3 application or notified through a self-assessable change.
