We are aware of an issue causing the title of some ARTG entries to disappear. We are investigating as a priority and hope to have this resolved as soon as possible.
Background
All listed medicines (AUST L listed medicines and AUST L(A) assessed listed medicines) may only contain ingredients included in the Therapeutic Goods (Permissible Ingredients) Determination (‘the Permissible Ingredients Determination’).
For a substance to be permitted for use as an ingredient in listed medicines, an applicant must apply for evaluation of a substance for use in listed medicines. The TGA will evaluate the substance to determine whether it is of appropriate safety and quality to be permitted for use as an ingredient in listed medicines. Once the substance is determined to be safe, it is included in the Permissible Ingredients Determination.
What has changed?
The TGA has introduced Mandatory requirements for applications to vary the Permissible Ingredients Determination under section 26BD of the Therapeutic Goods Act 1989, and accompanying guidelines. These came into effect on 1 February 2023 and only apply to new applications submitted from this date.
These requirements specify what information, and how that information must be provided for an application to pass preliminary assessment and progress to the evaluation phase, consistent with other therapeutic goods application processes. This ensures that applications are accepted for evaluation if they have sufficient information that would be required to undertake a meaningful and efficient evaluation of the safety and quality of the substance to be approved. The requirements have been tailored for different types of substances and routes of administration, whilst continuing to allow justifications to be provided for individual circumstances or approaches not covered in the guidance.
As part of this work, the IN1 new substance application category was also amended through the Therapeutic Goods Legislation Amendment (2022 Measures No. 3) Regulations 2022 in December 2022. The amendment means IN1 applications (that have reduced fees and or shorter evaluation times) can now be submitted to support safety based on evaluation reports from Comparable Overseas Bodies (COBs) and quality based on a monograph contained in a default standard.
In developing these requirements the TGA has consequentially updated other supporting documents that relate to the evaluation of new substances, including updating the list of COBs for which evaluation reports are accepted for use in abridged evaluation categories. For example, the COB list now permits reports from the European Scientific Committee on Consumer Safety to support safety and quality of excipient and active substances for dermal use as part of IN1, IN2 or IN3 applications. Reports were previously only permitted to support the safety of excipients in an IN1 or IN2 application. The TGA has also developed new guidelines to assist applicants applying for a new microorganism (i.e. probiotics and postbiotics) in listed medicines or registered complementary medicines.
