Global trends in clinical trials and interventions for the metabolic syndrome: A comprehensive analysis of the WHO International Clinical Trials platform.

ABSTRACT

Metabolic syndrome has emerged as a significant global public health concern, necessitating comprehensive examination alongside cardiovascular diseases (CVDs) and type 2 diabetes mellitus (T2D). This study provides a comprehensive analysis of clinical trials, drawing upon data sourced from the International Clinical Trials Registry Platform (ICTRP), until April 2023. Information pertaining to trial attributes and intervention features was gathered and subsequently summarized. Among the 2379 studies found on ICTRP from 18 clinical registries, ClinicalTrials.gov was the most popular with 55 % of the studies, based on data emerging from the United States. Most trials were for treatment (44 %) and prevention (17 %), with fewer focused on basic science, and diagnostic purposes. Diet and exercise were the most prominent, with 710 and 247 studies, respectively. Metformin and statins emerge as leading pharmacological therapies, reflecting the prevalence of CVD and T2D in the context of metabolic syndrome. However, there is growing recognition of other promising interventions, such as Glucagon-Like Peptide-1 agonists and Dipeptidyl Peptidase IV inhibitors, which offer potential in slowing the progression of metabolic syndrome-related conditions. Notably, clinical trials primarily assessed diagnostic markers like lipid profiles, insulin, and blood pressure, rather than body mass and body mass index. These parameters are crucial for evaluating the effectiveness and safety of interventions for metabolic syndrome due to its multi-condition nature. Most studies aimed to address general symptom relief, while highlighting a need for additional well-designed treatment trials with rigorous methodologies in accordance with the World Health Organization's guidance for consistent evaluation and treatment.
