Article Abstract
Clinical trials are essential in the development of new medical treatments, offering crucial data on their safety and effectiveness. This study provides a comprehensive analysis of clinical trials registered on ClinicalTrials.gov, examining the current landscape, challenges, and innovations that have shaped the field over the past century. Data were extracted on 7 March 2025 and analyzed to identify patterns in trial design, sponsorship, participant demographics, and geographical distribution. The analysis reveals a continuous increase in clinical trial registrations, peaking in 2021, driven by the COVID-19 pandemic. Most trials focus on cancer, reflecting its global burden, with randomized controlled trials (RCTs) being the most common study design. However, challenges persist, including underrepresentation of certain demographics, limited global distribution, and insufficient reporting of trial results. Additionally, the underrepresentation of pediatric, elderly, and minority populations in trials limits the generalizability of findings. The analysis underscores the need for more inclusive and globally distributed research to address disparities in health outcomes.

Randomized trial of activated vitamin D for acute kidney injury prevention in critically ill patients.
JCI Insight
September 2025
Division of Nephrology, Boston University Chobanian & Avedisian School of Medicine, Boston, United States of America.
Background: Active vitamin D metabolites, including 25-hydroxyvitamin D (25D) and 1,25-dihydroxyvitamin D (1,25D), have potent immunomodulatory effects that attenuate acute kidney injury (AKI) in animal models.
Methods: We conducted a phase 2, randomized, double-blind, multiple-dose, 3-arm clinical trial comparing oral calcifediol (25D), calcitriol (1,25D), and placebo among 150 critically ill adult patients at high-risk of moderate-to-severe AKI. The primary endpoint was a hierarchical composite of death, kidney replacement therapy (KRT), and kidney injury (baseline-adjusted mean change in serum creatinine), each assessed within 7 days following enrollment using a rank-based procedure.

Background: The loss of a loved one is a common yet stressful event in later life. Internet- and mobile-based interventions have been proposed as an effective treatment approach for individuals with prolonged grief.
Objective: The AgE-health study aimed to investigate the efficacy of an eHealth intervention, trauer@ktiv, in reducing prolonged grief symptoms in a sample of older adults.
Digital Psychological Intervention for Inflammatory Rheumatic Diseases: A Pilot Randomized Clinical Trial.
JAMA Netw Open
September 2025
Department of Psychiatry, Psychosomatics, and Psychotherapy, University of Lübeck, Lübeck, Germany.
Importance: Patients with inflammatory rheumatic diseases (IRDs) frequently experience psychological distress; however, access to psychological support remains limited.
Objective: To investigate the effectiveness of a digital psychological intervention for individuals with IRDs.
Design, Setting, And Participants: Participants aged 18 years or older were recruited across Germany between February 22 and June 4, 2024, if they had been diagnosed with rheumatoid arthritis, psoriatic arthritis, or systemic lupus erythematosus and reported psychological distress and reduced quality of life.
Parent/caregiver perspectives of meaningful improvement in functional domains for people with CDKL5 deficiency disorder: a mixed-methods study.
Qual Life Res
September 2025
The Kids Research Institute Australia, The University of Western Australia, P.O. Box 855, West Perth, WA, 6872, Australia.
Purpose: CDKL5 deficiency disorder (CDD) is a rare developmental and epileptic encephalopathy. Greater understanding of the smallest meaningful improvements for individuals with CDD in clinical trials and practice is needed for a person-centred approach to treatment efficacy. This study explored how parent/caregivers of people with CDD understood meaningful improvements and described change for priority functional domains including communication, gross motor, fine motor, feeding.
