Australian Public Assessment Report for Tafamidis and Tafamidis meglumine Proprietary Product Name: Vyndamax and Vyndaqel Sponsor: Pfizer Australia Pty Ltd September 2020 Therapeutic Goods Administration About the Therapeutic Goods Administration (TGA) • The Therapeutic Goods Administration (TGA) is part of the Australian Government Department of Health and is responsible for regulating medicines and medical devices. • The TGA administers the Therapeutic Goods Act 1989 (the Act), applying a risk management approach designed to ensure therapeutic goods supplied in Australia meet acceptable standards of quality, safety and efficacy (performance) when necessary. • The work of the TGA is based on applying scientific and clinical expertise to decision- making, to ensure that the benefits to consumers outweigh any risks associated with the use of medicines and medical devices. • The TGA relies on the public, healthcare professionals and industry to report problems with medicines or medical devices. TGA investigates reports received by it to determine any necessary regulatory action. • To report a problem with a medicine or medical device, please see the information on the TGA website <https://www.tga.gov.au>. About AusPARs • An Australian Public Assessment Report (AusPAR) provides information about the evaluation of a prescription medicine and the considerations that led the TGA to approve or not approve a prescription medicine submission. • AusPARs are prepared and published by the TGA. • An AusPAR is prepared for submissions that relate to new chemical entities, generic medicines, major variations and extensions of indications. • An AusPAR is a static document; it provides information that relates to a submission at a particular point in time. • A new AusPAR will be developed to reflect changes to indications and/or major variations to a prescription medicine subject to evaluation by the TGA.
