Implementing Decentralized Clinical Trials in Australia through Teletrials: Where to From Here?

Implementation of decentralized approaches can improve access to clinical trials. The Australian government has focused on a teletrial model, which resources and upskills health care organisations to enable collaboration in trials to extend to rural and remote areas. This commentary describes the Australian teletrial model, its context within the established DCT model, its value, and likely challenges moving forward.

Digital Health Technologies in Clinical Trials: An Ontology-Driven Analysis to Inform Digital Sustainability Policies

BACKGROUND

Digital health technologies (DHTs) can facilitate the execution of de-centralized trials that can offer opportunities to reduce the burden on participants, collect outcome data in a real-world setting, and potentially make trial populations more diverse and inclusive. However, DHTs can also be a significant source of electronic waste (e-waste). In recognition of the potential health and environmental impact from DHT use in trials, private and public institutions have recently launched initiatives to help measure and manage this e-waste. But in order to develop sound e-waste management policies, it will be necessary to first estimate the current volume of e-waste that results from the use of DHTs in trials.

MATERIALS AND METHODS

A Web Ontology Language (OWL)-compliant ontology of DHTs was created using a list of 500 DHT device names derived from a mixture of public and private sources. The U.S. clinical trials registry, ClinicalTrials.gov, was then queried to identify and classify trials using any of the devices in the ontology. The ClinicalTrials.gov records from this search were then analyzed to characterize the volume and properties of trials using DHTs, as well as estimating the total volume of individual DHT units that have been provisioned (or are planned to be provisioned) for clinical research.

RESULTS

Our ontology-driven search identified 2326 unique clinical trials with a reported "actual" enrollment of 200,947 participants and a "planned" enrollment of an additional 4,094,748 participants. The most-used class of DHTs in our ontology was "wearables," (1852 trials), largely driven by the use of smart watches and other wrist-worn sensors (estimated to involve 149,391 provisioned devices). The most-used subtype of DHTs in trials was "subcutaneous" devices (367 trials), driven by the prevalent use and testing of glucose monitors (estimated to involve 17,666 provisioned devices).

CONCLUSION

Thousands of trials, involving hundreds of thousands of devices, have already been completed, and many more trials (potentially involving millions more devices) are planned. Despite the great opportunities that are afforded by DHTs to the clinical trial enterprise, if the industry lacks the ability to track DHT use with sufficient resolution, the result is likely to be a great deal of e-waste. A new ontology of DHTs, combined with rigorous data science methods like those described in this paper, can be used to provide better information across the industry, and in turn, help create a more sustainable and equitable clinical trials enterprise.

"Click and mortar" opportunities for digitization and consumerism in trials

BACKGROUND

Digitization (using novel digital tools and strategies) and consumerism (taking a consumer-oriented approach) are increasingly commonplace in clinical trials, but the implications of these changes are not well described.

METHODS

We assembled a group of trial experts from academia, industry, non-profit, and government to discuss implications of this changing trial landscape and provide guidance.

RESULTS

Digitization and consumerism can increase the volume and diversity of trial participants and expedite recruitment. However, downstream bottlenecks, challenges with retention, and serious issues with equity, ethics, and security can result. A "click and mortar" approach, combining approaches from novel and traditional trials with the thoughtful use of technology, may optimally balance opportunities and challenges facing many trials.

CONCLUSION

We offer expert guidance and three "click and mortar" approaches to digital, consumer-oriented trials. More guidance and research are needed to navigate the associated opportunities and challenges.

Decentralized clinical trials in the trial innovation network: Value, strategies, and lessons learned

New technologies and disruptions related to Coronavirus disease-2019 have led to expansion of decentralized approaches to clinical trials. Remote tools and methods hold promise for increasing trial efficiency and reducing burdens and barriers by facilitating participation outside of traditional clinical settings and taking studies directly to participants. The Trial Innovation Network, established in 2016 by the National Center for Advancing Clinical and Translational Science to address critical roadblocks in clinical research and accelerate the translational research process, has consulted on over 400 research study proposals to date. Its recommendations for decentralized approaches have included eConsent, participant-informed study design, remote intervention, study task reminders, social media recruitment, and return of results for participants. Some clinical trial elements have worked well when decentralized, while others, including remote recruitment and patient monitoring, need further refinement and assessment to determine their value. Partially decentralized, or "hybrid" trials, offer a first step to optimizing remote methods. Decentralized processes demonstrate potential to improve urban-rural diversity, but their impact on inclusion of racially and ethnically marginalized populations requires further study. To optimize inclusive participation in decentralized clinical trials, efforts must be made to build trust among marginalized communities, and to ensure access to remote technology.

Digital health technologies and Alzheimer's disease clinical trials: might decentralized clinical trials increase participation by people with cognitive impairment?

BACKGROUND

Therapeutic trials in Alzheimer's disease (AD) face many obstacles-particularly with regard to screening and recruitment.

DISCUSSION

Decentralized clinical trials (DCTs) are being developed in other diseases and appear to be of value for overcoming these difficulties. The use of remote visits offers hope of broader recruitment and thus a reduction in inequalities due to age, geography, and ethnicity. Furthermore, it might be easier to involve primary care providers and caregivers in DCTs. However, further studies are needed to determine the feasibility of DCTs in AD. A mixed-model DCT might constitute the first step towards completely remote trials in AD and should be assessed first.

Participant comprehension and perspectives regarding the convenience, security, and satisfaction with teleconsent compared to in-person consent: A parallel-group pilot study among Danish citizens

Background

Teleconsent via video conferencing enables decentralized trials with remote consent and has the additional benefit of allowing a real-time reaction to potential misunderstandings. However, participant acceptance of and satisfaction with teleconsent versus in-person consent processes are unknown.

Methods

We conducted a parallel-group pilot study to evaluate participant comprehension and perspectives regarding the convenience, security, and satisfaction with teleconsent compared to in-person consent among Danish citizens for a hypothetical research study.

Results

There were no statistically significant differences in perceptions of security or satisfaction between teleconsent and in-person consent arms. However, participants viewed teleconsent as more convenient than in-person consent, as no transportation was needed and the process was less time-consuming. Recruitment was also faster in the teleconsent arm, and more people dropped out of the in-person arm, citing difficulties with transportation and time.

Conclusion

Decentralized clinical trials have been demonstrated to increase recruitment and enrollment rates, improve trial efficiency, and decrease dropout rates and trial delays. We add to this literature by suggesting that patients perceive teleconsent as similar to in-person consent, suggesting this is a feasible and acceptable substitution for in-person consent in multisite, decentralized trials. Future work should include patient perspectives from a larger, more diverse group of participants.

New Approaches to Regulatory Innovation Emerging During the Crucible of COVID-19 : In Responding to a Global Health Crisis, Industry is Discovering New, Efficient Ways of Meeting Objectives

The urgency and impact of the ongoing COVID-19 pandemic are changing global drug development and regulatory processes. The need for speed to understand the virus and develop new vaccines, medicines, and therapies for patients has provided unprecedented learning opportunities and revealed how the pharmaceutical industry can improve upon traditional processes. To stay competitive while remaining compliant with agency regulations and guidance, companies need to implement new process/tools that allow for more flexible work models, consider expanding the use of decentralized/hybrid trials, and capitalize on the use of real-world evidence (RWE) and cloud-based data systems. In addition, regulatory agencies should retain the agility exhibited during current reviews of potential new therapies, applying this momentum to other areas of unmet medical need. Further, agencies should consider a globally acceptable application platform. This article, by the Pharmaceuticals' Head of Regulatory Affairs at Bayer AG, examines how impacts of the COVID-19 crisis will continue beyond the pandemic period to the benefit of patients, drug developers, regulators, clinicians, and caregivers.
