Idiopathic pulmonary fibrosis (IPF) is a chronic progressive interstitial lung disease (ILD) of unknown aetiology with a median survival of only 3 years [1]. As a rare and orphan disease, IPF is difficult to study even within specialised referral centres and regional collaborative networks [2]. Although some local and regional prospective IPF registries exist, they generally do not share methodology and are not easily combined.
A global IPF registry would facilitate a better understanding of disease biology and behaviour [3], as well as identification of regional variations in diagnostic and management patterns that will help establish best practices [4]. Moreover, a global IPF registry would create a network for more efficient and affordable clinical trial conduct [5–7], and provide a platform for collaboration among stakeholders (patients, caregivers, clinicians, researchers, professional and scientific societies, industry partners, and governments).
We believe it is time to actively develop a global registry for IPF patients. The disease and the patients who suffer from it cannot wait. We propose a 5-year plan to achieve this goal (fig. 1).
Major steps and the timeline for the development of a global idiopathic pulmonary fibrosis (IPF) registry. It is anticipated that some of these steps will overlap/occur simultaneously rather than occur sequentially. ILD: interstitial lung disease.
Create the network
The first step in developing a global IPF registry is to identify capable, internationally acceptable sponsors to organise a global group of highly motivated IPF centres to serve as core members. A number of national advocacy groups and societal national organisations (e.g. the Pulmonary Fibrosis Foundation and the American Thoracic Society in the USA, and the British Lung Foundation and the British Thoracic Society in the UK) share many of the goals of a global IPF registry, and efforts to establish IPF networks have recently been undertaken in these and other countries. We believe that advocacy groups are best positioned to coordinate an international registry effort. They are the least constrained by regional considerations and biases, and as an advocate for patients they are in a unique position to balance input from all of the relevant stakeholders.
Secure initial funding
There are considerable costs associated with the development and management of a registry. A central electronic database, research coordination and data entry at each centre are necessary. If included, biospecimen procurement and storage adds significant expense. With focused objectives, feasible content and a solid business plan, we believe that funds can be secured to support a global registry effort. Advocacy groups, national organisations and industry sponsors will play a critical role early in this effort, with subsequent funding from government partners who will use the registry for research and administrative purposes.
Define the objectives
Successful registries need clearly defined and focused objectives. For example, a global IPF registry could identify geographic variability in patient characteristics and behaviour, or with how regional differences in practice patterns (including the use of approved drugs) impact on clinical outcomes. Specifying clear objectives early in the development process will provide focus, allowing distinction between essential and nonessential registry content. Defining the objectives would begin with collecting input from all stakeholders and creating an administrative structure to review this input and establish clear priorities.
Identify the content
Beyond demographics and outcome, there is no general consensus on what data should be collected; this should be dictated by the objectives identified. The balance between benefits and costs (both financial and logistical) need to be considered for each potential data element. table 1 summarises what we believe to be core content of a global IPF registry, regardless of the defined objectives. Biospecimens linked to clinical data are a valuable but costly and labour intensive addition. The inclusion of biospecimens in the initial registry will need to be carefully considered and need to be based on the registry’s stated objectives. Registry documentation of local biospecimen collection and banking at participating sites might be an initial approach.
Pilot and expand the registry
The operational details of a registry can be complex and will probably vary among sites. For example, privacy policies will differ between countries. Given the challenges associated with the initiation phase of a large multi-centred registry, we suggest a testing phase at core sites representing major geographical areas to identify problems and test procedures before full expansion to additional sites. These pilot sites could be selected from centres that have local registry infrastructure and personnel already in place.
Expansion of this registry to additional sites should be a priority, but must be carefully planned and regulated to ensure that data quality remains high and costs controlled. This will require close oversight from the registry’s governance. The number and locations of sites will be influenced by local factors, registry objectives and practical considerations (sources of funding and logistical realities). We also envisage gradual expansion of this registry to other ILDs beyond IPF. The relevant infrastructure for an ILD registry is included in the framework above, and the impact of a global IPF registry could be significantly enhanced by such an expansion.
Conclusion
We strongly believe that the time is right to develop a global IPF registry. Such a registry would fundamentally reshape the research landscape and provide unprecedented opportunity for progress toward better understanding and, ultimately, a cure for this terrible disease. There is currently momentum for registry creation at the national level in multiple countries; we hope the framework detailed above will provide a practical and feasible template for the expansion of this effort to a global scale, and that the IPF community will rally behind the opportunity to make a global IPF registry a reality.
