Opportunities and Challenges for Decentralized Clinical Trial Approaches: European Health Technology Assessment Perspective.

Objectives: Decentralized clinical trial (DCT) approaches are clinical trials in which some or all trial activities take place closer to participants' proximities instead of a traditional investigative site. Data from DCTs may be used for clinical and economic evaluations by health technology assessment (HTA) bodies to support reimbursement decision making. This study aimed to explore the opportunities and challenges for DCT approaches from an HTA perspective by interviewing representatives from European HTA bodies.

Direct-to-participant investigational medicinal product supply in clinical trials in Europe: Exploring the experiences of sponsors, site staff and couriers.

Aims: Insights into the current practice of direct-to-participant (DtP) supply of investigational medicinal product (IMP) in the context of clinical trials conducted in Europe are needed, as regulations are unharmonized. This study is set out to explore how DtP IMP supply has been employed in Europe and what the advantages and disadvantages and barriers and facilitators of its implementation are.

Methods: We conducted semi-structured interviews with representatives from sponsor companies, courier services and site study staff involved in the IMP dispensing and delivery process in Europe.

Decentralised, patient-centric, site-less, virtual, and digital clinical trials? From confusion to consensus.

There is increasing interest in clinical trials that use technologies and other innovative operational approaches to organise trial activities around trial participants instead of investigator sites. A range of terms has been introduced to refer to this operational clinical trial model, including virtual, digital, remote, and decentralised clinical trials (DCTs). However, this lack of standardised terminology can cause confusion over what a particular trial model entails and for what purposes it can be used, hampering discussions by stakeholders on its acceptability and suitability.

Validation of the GetReal Trial Tool - Facilitating discussion and understanding more pragmatic design choices and their implications.

Background: The GetReal Trial Tool is a decision support tool to assess the impact of design choices on generalizability of clinical trials to routine clinical practice, while taking into account the risk of bias, precision, acceptability and operational feasibility. This study describes the validation of the GetReal Trial Tool.

Methods: Twelve experts took part in the GetReal Trial tool validation using the protocols of 6 trials conducted with pragmatic elements.

A cross-sectional survey on the early impact of COVID-19 on the uptake of decentralised trial methods in the conduct of clinical trials.

Background: The COVID-19 pandemic significantly impacted the conduct of clinical trials through delay, interruption or cancellation. Decentralised methods in clinical trials could help to continue trials during a pandemic. This paper presents the results of an exploratory study conducted early in the pandemic to gain insight into and describe the experiences of organisations involved in clinical trials, with regard to the impact of COVID-19 on the conduct of trials, and the adoption of decentralised methods prior to, and as mitigation for the impact, of COVID-19.

Which decentralised trial activities are reported in clinical trial protocols of drug trials initiated in 2019-2020? A cross-sectional study in ClinicalTrials.gov.

Objectives: Decentralised clinical trial activities-such as participant recruitment via social media, data collection through wearables and direct-to-participant investigational medicinal product (IMP) supply-have the potential to change the way clinical trials (CTs) are conducted and with that to reduce the participation burden and improve generalisability. In this study, we investigated the decentralised and on-site conduct of trial activities as reported in CT protocols with a trial start date in 2019 or 2020.

Design: We ascertained the decentralised and on-site conduct for the following operational trial activities: participant outreach, prescreening, screening, obtaining informed consent, asynchronous communication, participant training, IMP supply, IMP adherence monitoring, CT monitoring, staff training and data collection.

Ethics review of decentralized clinical trials (DCTs): Results of a mock ethics review.

Decentralized clinical trials (DCTs) can be a valuable addition to the clinical trial landscape. However, the practice of DCTs is dependent on a regulatory system designed for conventional (site-based) trials. This study provides insight into the ethics review of DCTs.

Opportunities and Challenges for Decentralized Clinical Trials: European Regulators' Perspective.

Decentralized clinical trials (DCTs) have the potential to improve accessibility, diversity, and retention in clinical trials by moving trial activities to participants' homes and local surroundings. In this study, we conducted semi-structured interviews with 20 European regulators to identify regulatory challenges and opportunities for the implementation of DCTs in the European Union. The key opportunities for DCTs that were recognized by regulators include a reduced participation burden, which could facilitate the participation of underserved patients.

The GetReal Trial Tool: design, assess and discuss clinical drug trials in light of Real World Evidence generation.

Methodologies incorporating Real World Elements into clinical trial design (also called pragmatic trials) offer an attractive opportunity to assess the effect of a treatment strategy in routine care and as such guide decision making in practice. Uptake of these methods is slow for several reasons, including uncertainty about acceptability of trial results, lack of experience with the methodology and operational challenges. We developed the "GetReal Trial Tool," an easy-to-use online interface, which allows users to assess the impact of design choices on generalizability to routine clinical practice, while taking into account risk of bias, precision, acceptability and operational feasibility.

COVID-19 and the Emerging Regulatory Guidance for Ongoing Clinical Trials in the European Union.

The coronavirus disease 2019 (COVID-19) pandemic and the accompanying control measures have significantly affected clinical trial (CT) conduct, and sponsors have needed to make rapid changes to their CT operations. As a result, regulatory guidance was pivotal during the initial phases of the pandemic. This study aimed to evaluate the regulatory readiness and guidance related to COVID-19 in the European Union (EU).

Women in Translational Medicine: Tools to Break the Glass Ceiling.

Despite the recent movements for female equality and empowerment, few women occupy top positions in scientific decision-making. The challenges women face during their career may arise from societal biases and the current scientific culture. We discuss the effect of such biases at three different levels of the career and provide suggestions to tackle them.

Series: Pragmatic trials and real world evidence: Paper 5. Usual care and real life comparators.

Pragmatic trials may deliver real-world evidence on the added value of new medications compared with usual care and inform decision making earlier in development. This fifth paper in a series on pragmatic trials in the Journal discusses usual care as a comparator and the allocation of treatment strategies. The allocation and implementation of treatment strategies should resemble clinical practice as closely as possible.

Series: Pragmatic trials and real world evidence: Paper 1. Introduction.

This is the introductory paper in a series of eight papers. In this series, we integrate the theoretical design options with the practice of conducting pragmatic trials. For most new market-approved treatments, the clinical evidence is insufficient to fully guide physicians and policy makers in choosing the optimal treatment for their patients.

Series: Pragmatic trials and real world evidence: Paper 4. Informed consent.

The GetReal consortium of the Innovative Medicines Initiative aims to develop strategies to incorporate real-world evidence earlier into the drug life cycle to better inform health care decision makers on the comparative risks and benefits of new drugs. Pragmatic trials are currently explored as a means to generate such evidence in routine care settings. The traditional informed consent model for randomized clinical trials has been argued to pose substantial hurdles to the practicability of pragmatic trials: it would lead to recruitment difficulties, reduced generalizability of the results, and selection bias.

Stakeholders' views on the ethical challenges of pragmatic trials investigating pharmaceutical drugs.

Background: We explored the views of key stakeholders to identify the ethical challenges of pragmatic trials investigating pharmaceutical drugs. A secondary aim was to capture stakeholders' attitudes towards the implementation of pragmatic trials in the drug development process.

Methods: We conducted semistructured, in-depth interviews among individuals from different key stakeholder groups (academia and independent research institutions, the pharmaceutical industry, regulators, Health Technology Assessment (HTA) agencies and patients' organizations) through telephone or face-to-face sessions.

Pragmatic trial design elements showed a different impact on trial interpretation and feasibility than explanatory elements.

Objectives: To illustrate how pragmatic trial design elements or inserting explanatory trial elements in pragmatic trials affect validity, generalizability, precision, and operational feasibility.

Study Design And Setting: From illustrative examples identified through the IMI Get Real Consortium, we selected randomized drug trials with a pragmatic design feature. We searched all publications on these trials for information on how pragmatic trial design features affect validity, generalizability, precision, or feasibility.

Guideline-recommended use of asthma medication by children is associated with parental information and knowledge: the PIAMA birth cohort.

Purpose: We investigated the use of asthma medication by children and the association of use as recommended by guidelines with modifiable risk factors: parental attitudes, knowledge of asthma medication and information provided by health care providers.

Methods: Questionnaire data were obtained from parents of 229 8-year-old children participating in the prevention and incidence of asthma and mite allergy birth cohort who used asthma medication in the past 12 months. They reported on their child's medication use, their own knowledge and attitudes towards the medication and their satisfaction with the information they received from health care providers.

Patterns of asthma medication use: early asthma therapy initiation and asthma outcomes at age 8.

Wheeze has many underlying pathophysiologies in childhood, but is the main reason for anti-asthma drugs prescription. This study was conducted to describe asthma medication use patterns among children in their first eight years of life. Longitudinal medication use data from 777 children participating in the PIAMA study were used.

Asthma therapy during the first 8 years of life: a PIAMA cohort study.

Objective: Many studies evaluated asthma medication use in children in a cross-sectional manner, yet little is known about longitudinal use patterns. This study describes the formation of a longitudinal data set on asthma medication use and shows first results regarding the prevalence and incidence of medication use.

Methods: The PIAMA (Prevention and Incidence of Asthma and Mite Allergy) study is a prospective birth cohort study among 3963 Dutch children.

What drives prescribing of asthma medication to children? A multilevel population-based study.

Purpose: Diagnosing asthma in children with asthmatic symptoms remains a challenge, particularly in preschool children. This challenge creates an opportunity for variability in prescribing. The aim of our study was to investigate how and to what degree patient, family, and physician characteristics influence prescribing of asthma medication in children.

Prescription of respiratory medication without an asthma diagnosis in children: a population based study.

Background: In pre-school children a diagnosis of asthma is not easily made and only a minority of wheezing children will develop persistent atopic asthma. According to the general consensus a diagnosis of asthma becomes more certain with increasing age. Therefore the congruence between asthma medication use and doctor-diagnosed asthma is expected to increase with age.
