DORA - An Exploratory, Interventional Study Using Digital Health Tools and OneBiome to Explore the Impact of the Consumption of Senior Milk Powder Containing Synbiotics on the Gut micRobiome in Healthy Aging Individuals

The DORA study is a single-arm, open-label, interventional exploratory study designed to evaluate the impact of a synbiotic-containing senior milk powder on the gut microbiome and selected biological, physiological, and digital health parameters in community-living adults in good health.

The study enrolls adults aged 40 to 65 years and aims to investigate changes in gut microbial composition, with a primary focus on butyrate-producing microbial taxa, following at least 28 days of study product consumption. Secondary and exploratory objectives include assessment of stool metabolites, blood-based biomarkers, bowel patterns, sleep quality, physical activity, cognitive function, dietary patterns, and quality of life.

Approximately 125 participants will be recruited in Singapore to achieve 100 study completers. Following informed consent and screening, participants undergo a baseline observation period of 14 days during which physiological and lifestyle data are collected using wearable digital health devices. Baseline assessments also include blood sampling, stool collection for microbiome analysis, digital imaging and videography, and completion of validated questionnaires.

After completion of baseline assessments and collection of the first stool sample, participants initiate consumption of the study product, a senior milk powder containing a defined synbiotic formulation. The study product is consumed twice daily for a minimum of 28 days and up to 35 days to allow completion of study assessments.

Participants return for end-of-intervention assessments following the study product phase, including repeat biological sampling, physical and digital assessments, and questionnaires. Stool microbiome profiles and other exploratory outcomes are compared between baseline and post-intervention time points.

This exploratory study is intended to generate feasibility data and hypotheses regarding the effects of synbiotic nutritional intervention and the integration of biological and digital health data in the context of healthy aging.

Szczegółowy opis

Aging is a multifactorial biological process influenced by genetic, metabolic, environmental, and lifestyle factors. Increasing evidence suggests that the gut microbiome plays an important role in healthy aging, with associations reported across metabolic health, immune regulation, inflammatory processes, bowel function, cognition, and overall physiological resilience. Specific gut microbial communities, have been associated with favorable health outcomes and markers of healthy aging.

Synbiotics combine probiotics with complementary prebiotic substrates and are intended to selectively enhance beneficial gut microbial populations. The study product evaluated in the DORA study is a senior milk powder containing a defined synbiotic formulation.

Advances in digital health technologies now enable continuous and remote assessment of physiological, behavioral, and lifestyle parameters in daily living environments. The integration of wearable devices, mobile applications, and biological sampling allows the generation of longitudinal, multidimensional datasets. These approaches support exploratory research into physiological patterns relevant to healthy aging and facilitate investigation of potential digital biomarkers.

The DORA study is designed as an exploratory, single-arm nutritional intervention study to examine the effects of synbiotic consumption on gut microbiome-related outcomes in community-living adults in good health. The primary scientific focus is on gut microbiome composition, especially microbial taxa associated with short-chain fatty acid production. In addition, the study explores relationships between gut microbiome features and a range of biological, physiological, behavioral, and digital health parameters.

Participants undergo a baseline observation phase prior to study product initiation to characterize habitual health patterns and support within-participant comparisons over time. Following the intervention period, post-intervention assessments allow exploratory evaluation of changes relative to baseline. This longitudinal framework is intended to support descriptive and association-based analyses rather than formal hypothesis testing.

Beyond microbiome-related outcomes, the study includes exploratory assessments of stool-derived metabolites, blood-based biological biomarkers, bowel habits, dietary intake, sleep, physical activity, cognition, and quality of life. Digital health tools are used to capture continuous or near-continuous physiological and behavioral data, including activity, sleep patterns, heart rate-related measures, oxygen saturation, respiratory parameters, mobility metrics, and glucose profiles.

An additional exploratory component of the study is the integration of biological, clinical, and digital health data to support development of composite indicators and exploratory analytical models. Image-, video-, and sensor-based data are collected to assess feasibility and accuracy of advanced analytical approaches, including exploratory artificial intelligence methods. These analyses are conducted for research purposes only and are not intended for diagnostic or clinical decision-making.

The DORA study is exploratory in nature and is not designed to establish clinical efficacy, validate diagnostic tools, or demonstrate causal relationships. Findings will be interpreted descriptively, with emphasis on feasibility, data integration, variability, and observed associations. Results are intended to inform hypothesis generation, methodological development, and the design of future studies investigating nutritional strategies and digitally enabled assessment approaches in the context of healthy aging.
