About this study

The overall objective of this proposal is to explore the association between the administration of the prebiotics GOS (trade name: Bimuno Travelaid; generic name:B galacto-oligosaccharides) with pain, anxiety, and cognitive function in the perioperative period. The investigators' central hypothesis is subjects who consume GOS in the perioperative period will demonstrate lower levels of salivary cortisol before, during, and after their operative procedures. In addition, the investigators expect subjects who consume GOS to have lower perceived levels of anxiety during the perioperative period. Finally, the investigators hypothesize that subjects who consume perioperative GOS will perform better on tests of cognition in the postoperative period. Such a finding would be beneficial in that administration of GOS in the perioperative period offers a safe and inexpensive adjunct to current medical management of perioperative anxiety.

Read the detailed description

AIM 1: In anterior cervical decompression and fusion (ACDF) subjects, explore the association between prebiotics, anxiety, and pain.

Studies have recently elucidated a link between certain prebiotics and lower perceived anxiety as well as biomarkers of stress. In this aim the investigators will explore the association between consumption of prebiotics and their relationship to perioperative anxiety / physiological stress response. The investigators hypothesize that subjects who receive prebiotics will have lower perioperative anxiety and stress versus control as measured by standardized surveys and biomarkers. Furthermore, the investigators hypothesize that lower anxiety will result in lower postoperative pain scores.

AIM 2: In ACDF patients, explore the association between GOS and post-operative cognitive dysfunction.

Stress and anxiety is known to impair cognitive function. In addition, in preclinical studies, the administration of distinct keystone bacterial strains improves cognitive function in an anxious mouse model. In humans, prebiotics and probiotics have been shown to ameliorate the stress response. In this aim the investigators seek to explore the association between prebiotics and perioperative cognitive outcomes in humans. The investigators will perform cognitive function testing using the same time-tested battery used in the department to study post-operative cognitive decline (POCD). Subjects will be tested for cognitive function preoperatively (T1) and at 1.5 months post-op (T4). The investigators hypothesize that patients receiving prebiotics during the perioperative period will show less post-operative cognitive dysfunction than controls.

A total of 8 subjects will be recruited from the Neurosurgery Clinics of Duke University Health System. The target population will include subjects undergoing ACDF. Exclusion criteria will include: pregnant women, age<21 years, a diagnosis of depression, mental or behavioral disorder, recent anxiolytic use, long-term opiate use, oral contraceptive use, or recent antibiotic use.

What participants receive

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

  • Galacto-OligosaccharideDrug

    Mixture produced from lactose utilizing the transgalactosidic activity of Bifidobacterium bifidum NCIMB 41171 beta-galactosidase

  • Maltodextrin (Placebo)Drug

    Maltodextrin is a polysaccharide commonly used as a food additive. It is produced from starch by partial hydrolysis.

Study groups in NCT02953691
Study groupRoleWhat they receive
Galacto-Oligosaccharides (GOS)ExperimentalClasado Biosciences Limited will provide Bimuno Pastilles for the clinical trial. Each pastille contains 0.92g GOS and will be taken 3 times per day. Following informed consent, subjects will be issued prepackaged GOS pastilles to be taken three times daily up until the evening prior to surgery. Subjects will be randomly assigned to receive GOS prebiotics. Each subject has an equal chance of receiving GOS or placebo. GOSn will be administered in the hospital when patient reinstitutes oral intake. GOS will be issued to each subject to last until the day of their scheduled follow-up for POCD (approximately 1.5 months post surgery).

Maltodextrin (Placebo)Placebo comparatorClasado Biosciences Limited will provide placebo (Maltodextrin) for the clinical trial. Each pastille contains maltodextrin and will be taken 3 times per day. Following informed consent, subjects will be issued prepackaged pastilles to be taken three times daily up until the evening prior to surgery. Subjects will be randomly assigned to receive GOS prebiotics or placebo. Each subject has an equal chance of receiving GOS or placebo. Placebo will be administered in the hospital when patient reinstitutes oral intake.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Galacto-Oligosaccharide in people with Anxiety and Pain, run by Jeff Taekman, M.D. at 1 site in United States.

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 1 inclusion and 9 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: withdrawn, as of the sponsor's last update on 31 Jan 2018. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Change in Waking Salivary Cortisol (time frame: Morning after Preop Clinic Visit (2 weeks prior to surgery), 2-hours before surgery, 1-day after surgery, 6-week follow-up visit). 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 NCT02953691, which also lists 2 linked publications.

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 31 Jan 2018.
