Presentation overview

Implemented and ongoing reforms

• Variations to prescription medicines - notifications
• Comparable Overseas Regulator (COR) reports and work-sharing
• Biological and biosimilar medicines naming
• Regulation of autologous human cells and tissues
• Labelling – half-way through transition period

Upcoming reforms

• Neuromuscular blocking agents (NMBA)
• Faecal Microbiota Transplantation (FMT)
• Continual improvement – generic medicines

Prescription Medicines Variations e-Form

• Launched in mid-2017
• Since then > 2,000 submissions
• Changes to manufacturing information – current clearances needed for

all nominated manufacturers

• Modified December 2017

§ New change codes & descriptions added § Allow attachment of supporting data § Updated print preview § Introduction of notifications

Variations to prescription medicines

• Phase 1: Notifications for low risk changes to prescription medicines

– Launched 4 December 2017 – Must be submitted using the e-form – c. 330 notifications submitted, affecting over 1,000 ARTG entries

• Phase 2: Investigating further improvements to our risk-based

approach for variations

Comparable Overseas Regulator (COR) report-based process

From 2 January 2018

• For prescription medicines with full marketing approval from a

COR following a de novo evaluation.

• Six overseas regulators identified as CORs.
• Unredacted COR evaluation reports must be provided by the

applicant.

• Two approaches*:

– COR-A 120 working days – COR-B 175 working days

*depending on extent of TGA evaluation required.

Work-Sharing

• Simultaneous evaluation between multiple CORs

– Current work with ACSS partners – Joint evaluation report – Independent decision-making – Creation of template documents, alignment between agencies – Early stages

Biological and biosimilar medicines naming

• Consultation in 2017

– Improve collection of information on adverse events

• Government’s decision

– maintain existing convention i.e. continue using the Australian biological name (without a suffix) – mandatory reporting of product's trade name & non-proprietary name, when reporting an adverse event to TGA

Regulation of autologous human cells & tissues

• Historically seen as medical practice and outside TGA’s regulatory oversight.
• Growing global concern with direct to consumer advertising of unproven autologous

stem cell interventions.

• Consultation on reforms in 2015 & 2016
• October 2017 government decision announced
• Level of regulation (as biologicals) determined by the risk posed to patient safety
• Drafting regulatory guidance & amendments to regulations

Labelling Reform

New TGO 91 implemented 2016 Four year transition period We are half-way through! All medicine labels must meet new TGO requirements by 2020

8

Key updates to medicine labels

• Prominence of active ingredient

– Immediately below the name of the medicine.

• Name of the medicine

– As it appears on the Certificate of Registration.

• Schedule 1 – Declarable substances

– New requirement for prescription medicines – Includes declarations for substances that are not ingredients.

9

Key updates to medicine labels

• Contrasting colours

§ Required for information on medicine label c.f. background.

• Machine readable code

§ May be used to include information such as batch number & expiry date.

• International Harmonisation of Ingredient Names

§ Australian approved names list, & formulation details for all affected ARTG entries updated with new ingredient names § Transition period for labels & product information until 2020 § Dual-labelled names ‘new name (old name)’ until 2023.

10

We all use medicine labels

• Frequent enquiries from consumers &

industry – interest level is high!

• New webpage for consumers
• New webpage for health professionals
• Input to newsletters
• Social media
• Update to labelling guidance published soon

11

Changes to the labelling of Neuromuscular Blocking Agents (NMBAs)

• NMBAs are paralysing agents.
• Administration errors involving NMBAs

§ Can cause serious harm § Linked to look-alike labelling & packaging.

• Sponsors, healthcare groups & TGA working together to introduce a visual cue

§ Warning statements § Colour coding.

12

Regulation of donation, manufacture & supply of Faecal Microbiota Transplantation (FMT) material

• ‘FMT material’ = donated human stool for application in humans
• Increasing attention on use of FMT for treatment of recurrent Clostridium

difficile infection

• Hospitals & clinics offering FMT material for the treatment of C. diff. & other disorders.
• No FMT material is entered as approved goods on ARTG
• Access as unapproved goods, e.g. clinical trial, SAS or authorised prescriber
• TGA is developing a position paper on regulatory status of current supply.

13

Regulation of donation, manufacture & supply of FMT material

FMT material may often meet the definition of a ‘biological’ under Section 32A of the Therapeutic Goods Act:

• It comprises, contains or is derived from human cells (e.g. colonocytes) or human

tissues. FMT material that is banked:

• multiple donations are combined & processed for use in unrelated patients
• poses similar risks of infectious disease transmission as for other biological banks, e.g.

eye banks.

14

Regulation of donation, manufacture & supply of FMT material

• Biologicals are regulated by the TGA under the regulatory framework for biologicals

– different levels of regulation of products based on the risks associated with their use. Possible changes for FMT material to address safety concerns:

• 1. New Standard specific to donor selection & screening for FMT material
• 2. Transition towards all manufacture of FMT material under GMP (exemption: phase 0 or

phase I clinical trials)

• 3. Information on TGA website to clarify requirements for supply & restrictions to

advertising unapproved therapeutic goods

Safety First!

Further reforms and improvements - Context

Government:

• MMDR reforms – new

pathways, shorter timeframes

• PBS expenditure – more

expensive drugs for smaller populations

• Affordable & sustainable

health system, especially PBS

• Patient expectations for early

access to cheaper medicines

• Recruitment controls

Sponsors’ feedback:

• Generics take almost as

long as NCEs

• Milestones important for

predictability

• Appreciate cooperative

approach to get products

• ver the line
• Focus on material

aspects Industry 4.0:

• Changing profile of

new medicines – more complex generics but fewer

• verall
• Increase in NCEs &

biosimilars & shift to immunotherapeutics & personalised medicines
