This paper presents the operational insights gained from selecting, training, and supporting clinical sites within the RADIAL proof-of-concept trial, part of the Trials@Home project. RADIAL was a multicenter, low-intervention phase IV trial comparing conventional, hybrid, and fully decentralized approaches for individuals with type 2 diabetes mellitus across six European countries. Site selection involved detailed feasibility assessments evaluating operational capabilities, recruitment potential, technological readiness, and willingness to implement decentralized elements. Despite proactive training, including ongoing support via a centralized helpdesk, sites faced initial difficulties with technology management and participant onboarding. Contractual complexities were prominent, particularly regarding clearly delineating responsibilities and data handling in agreements involving third-party providers. Moreover, integrating third-party services necessitated meticulous oversight strategies and continuous stakeholder coordination to ensure regulatory compliance and efficient trial management. Our experiences underscore essential considerations for future DCT implementations: proactive stakeholder alignment; tailored, timely, and ongoing training and support; intuitive technology design informed by clinical user input; robust, centralized oversight structures; and clearly defined delegation frameworks for third-party engagements. Addressing these operational considerations will facilitate smoother transitions toward decentralized clinical research models, maximizing their potential benefits while managing associated complexities effectively-especially for clinical site staff.</p>","PeriodicalId":153,"journal":{"name":"Clinical Pharmacology & Therapeutics","volume":" ","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145204988","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

New drugs and regenerative medical products applications approved by the Ministry of Labour, Health, and Welfare between January 1, 2019, and December 31, 2024, were included (N = 674). Of these, 158 (23.4%) applications contained RWD/E. The number of RWD/E use cases increased continuously over the period from 21 (18.1%) of applications in 2019 to 38 (30.4%) of applications in 2024. 75% of use cases categorized as the main study were used to provide comparator arms in clinical trials. Most of the cases were employed because a randomized controlled trial was ethically difficult or infeasible. In pediatric drug applications, RWD/E were leveraged to address the low feasibility of clinical trials and ethical concerns, with a relatively higher use for safety purposes (40%) observed. Alongside the development of regulatory initiatives, the findings confirm the increasing number and variety of RWD/E utilization.

The microbiota can also affect drug efficacy or toxicity by modulating the immune system; for example, variability in response to cancer immunotherapy, such as anti-PD-1 and anti-CTLA-4 therapies, is increasingly attributed to differences in gut microbial composition and function. These conditions indicate the need and opportunity to intentionally leverage the microbiome for drug effect; as such, the study of how intra- and inter-individual differences in the microbiome affect drug response has gained a definition termed pharmacomicrobiomics. While the need is clear, clinical studies evaluating pharmacomicrobiomic interactions are challenging due to microbiome variability, multiple potential confounders, no standardization of statistical and bioinformatics methods, and the reluctance of potential clinical study participants. In this review, we make the case for pharmacomicrobiomic clinical studies; for the use of modeling and simulation to provide a quantitative framework for data integration, hypothesis testing, and translational-to-late-stage clinical predictions; and the application of real-world data to support both using a within-subject comparison approach. We argue that an integrated and cohesive approach can address the large \"inherent\" inter-individual variability in the microbiome, attributed to factors such as age, lifestyle choices, environmental factors, chemical and biological exposures, and disease. In summary, there are many challenges to pharmacomicrobiomics research but also enormous potential to improve the development and utilization of pharmaceutical products.</p>","PeriodicalId":153,"journal":{"name":"Clinical Pharmacology & Therapeutics","volume":" ","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145184399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study compared the effects of CCBs and ACEi on progression-free survival (PFS) in ovarian cancer patients treated with adjuvant bevacizumab. The incidence of MACE and overall survival (OS) were also evaluated. We conducted an emulated clinical trial using data from January 1, 2011, to January 1, 2021, from the French National Health Data System (SNDS), covering 98.8% of the French population. Patients with FIGO stage III to IV ovarian cancer who underwent cytoreductive surgery and adjuvant chemotherapy with bevacizumab, treated with CCBs or ACEi monotherapy within 6 months after surgery, were included. Out of 4,165 patients treated with bevacizumab, 454 met inclusion criteria for the main analysis: 273 in the CCBs group and 181 in the ACEi group. CCBs use was associated with a longer median PFS compared to ACEi (21.8 vs. 18.2 months) and a higher 3-year PFS rate (difference of 8.2 percentage points, 95% CI: 2.0%; 14.8%).

Cardiovascular complications were more frequent with CCBs compared to ACEi, particularly congestive heart failure (difference in 3-year incidence of MACE: -4.5 percentage points; 95% CI: -8.2%; -1.1%).

In RADIAL, 68 DtP IMP shipments were executed with a 94% successful delivery rate. Four shipments (6%) failed due to participant unavailability, temperature excursions, defective monitoring equipment, or courier loss. The central pharmacy model demonstrated inventory savings compared with conventional site-based distribution. Biological sample collection for HbA1c assessment was done through drop-off, which proved more challenging in the remote arm. Key challenges related to DCT logistics as experienced in RADIAL included unclear importer/exporter responsibilities, regulatory divergence across countries, participant material management, and sample drop-off reliability.

However, ETI has been shown in clinical trials to cause elevations in liver enzymes, and real-world cases of drug-induced liver injury (DILI) have also been reported. The mechanism of ETI-mediated DILI is currently unknown, hindering the development of more effective mitigation strategies for this adverse reaction. Through in vitro assays and quantitative systems toxicology modeling using DILIsym, this study revealed that ivacaftor contributed most significantly to ETI-mediated DILI, primarily via reactive oxygen species production, resulting in mitochondrial dysfunction due to electron transport chain inhibition. DILIsym modeling also predicted liver enzyme elevations following daily dosing of ETI at a comparable frequency (6.0%) to that of clinical data (8.0%).

This paper presents operational learnings from the Trials@Home RADIAL proof-of-concept trial. RADIAL implemented a modular, multi-vendor technology package. RADIAL adopted a deliberate strategy to avoid a monolithic \"one-vendor-for-all\" solution, instead selecting technologies and integrating them only where it added clear value. Core systems-such as eConsent and Bluetooth glucometer-were fully integrated into the central platform, while other components were deliberately managed outside the core system. The aim was to implement and validate a multi-vendor technology setup and generate learnings that would help DCT trialist in designing DCTs, especially in terms of technology selection and integration. Key challenges arose from Bring Your Own Device (BYOD) variability, immature device technologies, and infrastructure limitations at clinical sites-particularly affecting components like telemedicine. The results emphasize the significance of investing in participant support infrastructure, as well as early cross-functional support, while automated, multichannel notifications seem to guide participant engagement.
