Pregnancy category

B3

Drugs which have been taken by only a limited number of pregnant women and women of childbearing age, without an increase in the frequency of malformation or other direct or indirect harmful effects on the human fetus having been observed.

Studies in animals have shown evidence of an increased occurrence of fetal damage, the significance of which is considered uncertain in humans.

The use of any medicine during pregnancy requires careful consideration of both risks and benefits by the treating health professional. This must not be used as the sole basis of decision making in the use of medicines during pregnancy. The TGA does not provide advice on the use of medicines in pregnancy for specific cases. More information is available from obstetric drug information services in your State or Territory.

What post-market commitments will the sponsor undertake?

  • Crysvita (burosumab) is to be included in the Black Triangle Scheme. The Product Information (PI) and Consumer Medicines Information (CMI) for Crysvita 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 Crysvita European Union (EU)-Risk Management Plan (RMP) (version 2.1, dated 31 March 2020; data lock point 18 February 2019), with Australian Specific annex (version 1.3, dated 26 February 2021), included with submission PM-2020-03892-1-5, 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 the 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.

  • Laboratory testing & compliance with Certified Product Details
    • All batches of CRYSVITA supplied in Australia must comply with the product details and specifications approved during evaluation and detailed in the Certified Product Details (CPD).
    • When requested by the TGA, the Sponsor should be prepared to provide product samples, specified reference materials and documentary evidence to enable the TGA to conduct laboratory testing on the Product. Outcomes of laboratory testing are published biannually in the TGA Database of Laboratory Testing Results and periodically in testing reports on the TGA website.

      Certified Product Details

      The 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.

  • The sponsor is required to update the relevant Good Manufacturing Practice (GMP) clearances to reflect the appropriate steps in the manufacturing process included in the ARTG record. This could be done at the next time a GMP clearance is required but should be completed within the next 12 months.
  • For all injectable products the Product Information must be included with the product as a package insert
