For further information refer to the Product Information. |
| 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 was approved?
Trikafta (elexacaftor/tezacaftor/ivacaftor and ivacaftor) was approved for the following therapeutic use:
Trikafta is indicated for the treatment of cystic fibrosis (CF) in patients aged 12 years and older who have at least one F508del mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene.
What is this medicine and how does it work?
Elexacaftor and tezacaftor are cystic fibrosis transmembrane conductance regulator (CFTR) correctors that bind to different sites on the CFTR protein and have an additive effect in facilitating the cellular processing and trafficking of F508del-CFTR to increase the amount of CFTR protein delivered to the cell surface compared to either molecule alone. Ivacaftor potentiates the channel open probability (or gating) of the CFTR protein at the cell surface.
The combined effect of elexacaftor, tezacaftor and ivacaftor is increased quantity and function of F508del-CFTR at the cell surface, resulting in increased CFTR activity as measured by CFTR mediated chloride transport. Clinical outcomes were consistent with in vitro results and indicate that a single F508del mutation is sufficient to result in a significant clinical response (see Clinical Efficacy section of the Product Information).
What was the decision based on?
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 Trikafta was considered favourable for the therapeutic use approved.

What post-market commitments will the sponsor undertake?
- Trikafta (elexacaftor/tezacaftor/ivacaftor) is to be included in the Black Triangle Scheme. The Product Information (PI) and Consumer Medicines Information (CMI) for Trikafta must include the black triangle symbol and mandatory accompanying text for five years, which starts from the date that the sponsor notifies the Therapeutic Goods Administration (TGA) of supply of the product.
- The Trikafta European Union (EU)-risk management plan (RMP) (version 1.1, dated 21 August 2020; data lock point dated 20 July 2020), with Australian specific Annex (version 2.0, dated 18 September 2020), included with submission PM-2020-00642-1, 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.
