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

Onakta (tirbanibulin) was approved for the following therapeutic use:

Onakta is indicated for the topical field treatment of non-hyperkeratotic, nonhypertrophic actinic keratosis of the face or scalp in adults.

What is this medicine and how does it work
Tirbanibulin disrupts microtubules by direct binding to tubulin, which induces cell cycle arrest and apoptotic death of proliferating cells and is associated with disruption of Src tyrosine kinase signalling.
What post-market commitments will the sponsor undertake
  • Onakta (tirbanibulin) is to be included in the Black Triangle Scheme. The PI [Product Information and CMI [Consumer Medicine Information] for Onakta 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 Onakta EU [European Union]-risk management plan (RMP) (version 0.7, dated 10 May 2021, data lock point 10 October 2019), with Australia-specific annex (version 2.0, dated 10 March 2023), included with Submission PM-2022-02492-1-1, 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 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. Each report must have been prepared within ninety calendar days of the data lock point for that report.

  • Submission of the results of the ongoing, EU 3-year safety study (PASS) to the TGA, when available.
