About this study
Official title: Vitality Oriented Innovation for the Lifecourse of the Ageing Society Intervention Study
The multi-disciplinary and translational VOILA project presents a unique intersection between gut, immuno-metabolic, and musculoskeletal health. The main goals of the project are to develop biomarkers for healthy aging and prevent disease by maintaining quality of life in older adults. Within this umbrella project, the multimodal VOILA lifestyle intervention study will assess the impact of a twelve-week strength training and nutritional intervention in older adults with different degrees of mobility. The study will improve the current understanding of the complex relationship between gut and muscle health in different segments of mobility and obtain an insight into the heterogeneity of responsiveness between individuals.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
VOILACombination product
Participants will be given dietary supplement powder containing protein, galactooligosaccharide (GOS), vitamin D, and calcium throughout the twelve weeks of intervention. This will be accompanied with a resistance training regime whereby participants will train three times a week for the three months. A variety of measurements will be carried out at baseline and at endline.

Questions about this trial
What is this clinical trial studying?
A study testing VOILA in people with Aging, run by Leiden University Medical Center at 3 sites in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 15 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 29 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact P. Eline Slagboom, PhD (0653879941 ext. 31, P.Slagboom@lumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Muscle mass (time frame: 10 weeks). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05354310, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2022; AzTrials last refreshed its copy on 3 Nov 2026.
