Post-market Review of Chronic Obstructive Pulmonary Disease (COPD) Medicines
Page last updated: 4 March 2016
COPD is characterised by a chronic inflammation of the lung tissue, and obstruction of the airways that cannot be fully reversed by medication. Air flow obstruction leads to symptoms such as wheezing, shortness of breath, chest tightness, coughing, and production of excess mucus. Symptoms can be exacerbated by irritants such as infection or exposure to noxious particles or gases, most commonly cigarette smoke.
A number of medicines are available to reduce the symptoms of COPD, and to reduce the frequency and severity of exacerbations. The primary medicines are bronchodilators (beta2-agonists, anti-cholinergics/muscarinic agonists, phosphodiesterase inhibitors and methylxanthines) to reduce airway obstructions, and inhaled corticosteroids to reduce inflammation.
In October 2013, the Drug Utilisation Sub-Committee (DUSC) of the Pharmaceutical Benefits Advisory Committee (PBAC) reviewed the Pharmaceutical Benefits Scheme (PBS) utilisation of indacaterol and budesonide/efomoterol for COPD. The review of indacaterol utilisation identified co-administration of multiple long-acting beta agonist (LABA) products in some patients, which was considered a significant quality use of medicines issue.
The review of budesonide/eformoterol found a trend towards higher initiations in winter which the DUSC considered may indicate use for the treatment of respiratory tract infections or cough, a quality use of medicines issue. The relevant DUSC meeting outcome statement is available below:

In July 2014, when considering the submissions for indacaterol/glycopyrronium and umeclidinium/vilanterol the PBAC noted that while forced expiratory volume in 1 second (FEV1) has previously been accepted as a surrogate outcome in the treatment of COPD, the PBAC were concerned that this may not translate into clinically meaningful benefits to patients. These submissions did not provide evidence of reductions in exacerbations or hospitalisations, outcomes that the PBAC considered could also be used to demonstrate effectiveness. The PBAC further noted concerns by the DUSC that the introduction of these fixed dose combinations may lead to patients being initiated on the combination product earlier than clinically appropriate and without adequate titration of the individual components. Further information is available in the PBAC Public Summary Documents for July 2014 for these medicines.
In August 2015, the PBAC recommended a Post-market Review of COPD Medicines, noting that a number of new combinations, including long-acting muscarinic antagonist (LAMA)/LABA and LABA/inhaled corticosteroid (ICS) combinations, have been listed recently on the PBS and that there was concern about use of multiple products.
The purpose of the Post-market Review of COPD Medicines is to review the utilisation, safety, efficacy and cost-effectiveness of PBS listed COPD medicines, and to address quality use of medicines concerns associated with the apparent use of multiple products. This Review was approved by the Minister for Health on 28 September 2015.
The Review is being carried out under the Australian Government’s post-market monitoring programme, which aims to ensure the continued safe, cost-effective and quality use of medicines listed on the PBS.
Medicines to be included in the COPD Review are:
- Medicines listed on the PBS for the treatment of COPD only:
- Indacaterol + Glycopyrronium
- Umeclidinium + Vilanterol
- Medicines listed on the PBS for the treatment of COPD and asthma:
- Budesonide + Eformoterol
- Fluticasone + Eformoterol
- Fluticasone + Salmeterol
- Fluticasone + Vilanterol
Consultation on Draft Terms of Reference
Public consultation on the draft Review Terms of Reference was open between 16 October 2015 and 13 November 2015.
Final Terms of Reference
The PBAC considered the draft Review Terms of Reference and comments from stakeholders at the December 2015 PBAC meeting. Following the December 2015 PBAC meeting the Minister for Health approved the final Terms of Reference for the Review:
- Compare the prescribing restrictions for PBS-listed COPD medicines for consistency with the current clinical guidelines.
- Review the clinical outcomes that are most important or clinically relevant to people with COPD and the extent to which these outcomes are included in the evidence previously provided to PBAC on the cost-effectiveness of these medicines.
- Review the evidence on the efficacy and safety of monotherapy and combinations of LABA/LAMA, ICS/LABA and LAMA + ICS/LABA (separate items or fixed dose combinations) for treatment of COPD that PBAC has not previously considered.
- Review the published literature on the safety of prolonged ICS use in monotherapy and in combination with LABA and/or LAMA for COPD that PBAC has not previously considered.
- Analyse the current utilisation of PBS listed COPD medicines to identify the extent of co-prescribing and use that is inconsistent with clinical guidelines and/or PBS restrictions.
- Evaluate if the current utilisation of multiple therapies and the latest evidence relating to safety and efficacy justifies a review of cost-effectiveness for some or all medicines indicated for COPD.
Public Submissions addressing the final Terms of Reference
The public submission process for the COPD Review opened on 4 March 2016. Interested organisations and individuals are invited to provide a submission addressing the Terms of Reference for the Review. To make a submission please go to the Public Consultation page.
This Review will follow the Post-market Review Framework available on the Reviews website. This process includes public consultation on the draft Terms of Reference, an opportunity to provide submissions to the Review, and an opportunity to comment on the draft Review Report.
Further information on post-market reviews is available on the Reviews website.
