Not applicable Interventional Fundación Pública Andaluza para la Investigación de Málaga en Biomedicina y Salud · NCT07554716

This trial will test whether giving melatonin and timing tube feeding to match patients' body clocks helps metabolism, sleep, and quality of life for hospitalized patients on enteral nutrition.

What this trial studies

Hospitalized patients who have received enteral nutrition for at least 15 days are compared between a control arm with standard continuous 24-hour feeding and an intervention arm that pairs timed nutrition with nightly melatonin. The protocol measures biological clock gene markers, metabolic parameters (carbohydrates, lipids, proteins), sleep quality, chronotype, and patient-reported quality of life. Participants must be able to provide informed consent (or have a legal representative) and complete questionnaires with or without family support. The aim is to determine whether synchronizing medical nutritional therapy with circadian rhythms reduces chronodisruption and related morbidity.

Who should consider this trial

Good fit: Ideal candidates are hospitalized adults on enteral nutrition for 15 days or more at the participating Spanish centers who can provide informed consent and complete questionnaires with or without family help.

Not a fit: Patients already taking melatonin, pregnant patients, those with uncontrolled psychiatric conditions, or those with recent acute metabolic decompensation are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, aligning feeding times and using melatonin could improve metabolic control, sleep, and overall well-being for patients on long-term enteral nutrition.

How similar studies have performed: Small studies of melatonin and circadian-targeted interventions have shown improvements in sleep and some metabolic markers, but synchronizing enteral nutrition timing is a relatively novel approach with limited prior clinical trial data.
