Pregnancy category
B3Drugs 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 was approved

Rukobia (fostemsavir trometamol) was approved for the following therapeutic use:

Rukobia is indicated in combination with other antiretroviral agents for the treatment of heavily treatment-experienced adults with multidrug-resistant human immunodeficiency virus-1 (HIV-1) infection for whom it is otherwise not possible to construct a suppressive antiviral regimen due to resistance, intolerance or safety considerations (see Section 5.1 Pharmacodynamic properties, clinical trials).

What is this medicine and how does it work
Fostemsavir is a prodrug without significant biochemical or antiviral activity that is hydrolysed to the active moiety, temsavir, upon cleavage of a phosphonooxymethyl group in vivo. Temsavir binds directly to the glycoprotein (gp)120 subunit within the human immunodeficiency virus-1 (HIV-1) envelope glycoprotein gp160 and selectively inhibits the interaction between the virus and cellular cluster of differentiation 4 (CD4) receptors, thereby preventing viral entry into, and infection of, host cells. Temsavir inhibited the binding of soluble CD4 to surface immobilised gp120 with a half maximal inhibitory concentration (IC50) of 14 to 30 nM using an enzyme linked immunosorbent assay.
What post-market commitments will the sponsor undertake
  • Rukobia (fostemsavir) is to be included in the Black Triangle Scheme. The Product Information and Consumer Medicine Information for Rukobia 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 Rukobia European Union (EU) - Risk Management Plan (RMP) (version 1.0, dated 15 January 2021, data lock point 6 September 2019), with Australian specific annex (version 1.2, dated April 2021), included with submission PM-2020-02898-1-2, 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.
