What post-market commitments will the sponsor undertake
- Palynziq (pegvaliase) is to be included in the Black Triangle Scheme. The Product Information and Consumer Medicine Information for Palynziq 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 Palynziq European Union (EU)-risk management plan (RMP), version 3.0, dated 6 October 2020, data lock point 17 April 2019), with Australian Specific annex (version 0.2, dated 5 March 2021) included with Submission PM-2020-04119-1-3, and any subsequent revisions, as agreed with the TGA will be implemented in Australia.
An obligatory component of RMP 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.
