About this study

Official title: A Randomized, Crossover Pilot to Examine the Acute Impact of Veillonella Supplementation on Exercise and Lactate Responses

The purpose of this study is to assess the health and performance outcomes associated with supplementation of Veillonella atypica.

Read the detailed description

This pilot study will be conducted using a randomized, double-blind, crossover study design. Healthy men and women (n=7) between the ages of 18 - 50 years of age will be recruited for this study. After signing an IRB-approved consent form, participants will have their peak VO2 determined to finalize eligibility. Eligible participants will then practice their first time to exhaustion trial at 100% VO2Peak. Prior to each subsequent study visit, participants will be scheduled at a similar time between the hours of 0600 and 1000 hours and will be asked to observe an overnight fast (food, caffeine, and nicotine) while refraining from any vigorous exercise for at least 24 hours prior to their visit. During visit 2, participants will have their body composition assessed and complete another time to exhaustion familiarization at 100% VO2Peak. Leading up to and during each subsequent study visit (identical to visit 3), participants will collect a stool sample and upon arrival at the laboratory have their body mass measured before having a venous blood sample collected for assessment of complete blood count and comprehensive metabolic panel. After blood collection, participants will complete the standardized warm-up before completing a treadmill time to exhaustion test at 100% VO2Peak. Capillary lactate levels will be assessed before, immediately after, and 5 minutes after completion of the exhaustion trial using a handheld lactate analyzer. From there and in a randomized, double-blind, placebo-controlled, crossover fashion, participants will be assigned for the next 14 days to ingest either a placebo (maltodextrin) or a 1 x 109CFU dose of Veillonella atypica FB004 (VA) (Fitbiomics, Inc. New York). After supplementing for 14 days, participants will complete an identical battery of tests. Participants will then follow a wash-out period for 21 days before returning to the laboratory to complete study visit 5, the pre-supplementation visit to their supplementation period. After completing study visit 5, participants will be instructed to supplement with the alternative supplement for 14 days before returning for a 6th and final study visit. Participants will complete a two-day food and fluid record prior to visit 3, receivea copy of it from study investigators, and be instructed to replicate it prior to each subsequent study visit.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Time to Exhaustion at velocity at VO2maxDietary supplement

    Also called TTW

    During a familiarization trial prior to supplementation and before and after each supplementation period at the beginning of each study visit, participants will complete a standardized warm-up consisting of walking on a treadmill for 5 minutes, a series of whole-body dynamic movements (high knees, butt kicks, walking lunges, straight-leg marching, etc.), and a self-prescribed period of jogging on the treadmill for no more than ten minutes. The speed on the treadmill will then be set at the velocity upon which 100% VO2Peak was achieved. Participants will be instructed to run at this velocity for as long as they can. No feedback in terms of duration, pacing, etc. will be provided, and participants will be provided verbal encouragement to run for as long as possible.

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 7 inclusion and 13 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: finished, as of the sponsor's last update on 18 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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. Some participants in this study may receive a placebo. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Aerobic Exercise Performance (time frame: 2 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Apr 2023.
