Study summary

This is a randomized, double-blind, double arm study involving 128 participants who will undergo a total participation period of 12 weeks.

Read the detailed description

The trial begins with a screening to assess eligibility, followed by a 12-week treatment phase during which participants will receive a fixed-dose oral supplementation regimen. During this treatment period, participants will take UltraFlora® Triplebiotic at a fixed dose of 2 capsule per day, administered orally once daily with food. During the 12-week treatment period, participants will be asked to complete questions and track their weight changes.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Study arms

  • Active comparator
    UltraFlora® Triplebiotic

    The duration of trial intervention and participation for an individual participant is approximately 3 months (12 weeks). Screening, during which eligibility to participate in the trial is assessed, occurs at baseline. A fixed, orally administered, dose of the study products (UltraFlora® Triplebiotic, 2 capsules/day) are taken daily with breakfast.

    Dietary Supplement: UltraFlora® Triplebiotic

  • Placebo comparator
    Orally administration of 2 capsules/day of placebo

    The duration of trial intervention and participation for an individual participant is approximately 3 months (12 weeks). Screening, during which eligibility to participate in the trial is assessed, occurs at baseline. A fixed, orally administered, dose of the placebo (2 capsules/day) are taken daily with breakfast.

    Dietary Supplement: Placebo

Interventions

  • Dietary supplementUltraFlora® Triplebiotic

    The duration of trial intervention and participation for an individual participant is approximately 3 months (12 weeks). Screening, during which eligibility to participate in the trial is assessed, occurs at baseline. A fixed, orally administered, dose of probiotic ( UltraFlora® Triplebiotics, 2 capsules/day) are taken daily with a glass of water.

What researchers measure

Primary outcomes

  1. weight measurement

    Evaluate the impact of UltraFlora Triplebiotic (containing Bifidobacterium Lactis B420 and pasteurized Akkermansia Muciniphila) on weight regain over 3 months after discontinuation of GLP-1.

    Time frame: From enrollment to the end of treatment at 12 weeks (90 days)

Secondary outcomes

  1. IBS-SSS (Irritable Bowel Syndrome - Severity Scoring System) questionnaire

    Evaluate the impact of UltraFlora Triplebiotic containing Bifidobacterium Lactis B420 and pasteurized Akkermansia Muciniphila on weight regain over 3 months after discontinuation of GLP-1. It is a visual analog scale ranging from 0 to 100 that allows the severity of patients' gastrointestinal symptoms to be assessed. The higher the score, the more pain the patient is experiencing.

    Time frame: From enrollment to the end of treatment at 12 weeks (90 days)

  2. SVS (Subjective Vitality Scale) questionnaire

    Evaluate the impact of UltraFlora Triplebiotic containing Bifidobacterium Lactis B420 and pasteurized Akkermansia Muciniphila on vitality using the Subjective Vitality Scales (SVS) questionnaire. This questionnaire assesses a state of well-being and optimal functioning in relation to independence and physical and psychological health. Scores range from 1 (very low vitality) to 7 (optimal vitality).

    Time frame: From enrollment to the end of treatment at 12 weeks (90 days)

  3. TFEQ-R18 (Three-Factor Eating Questionnaire - Revised 18 items) Questionnaire

    Evaluate the impact of UltraFlora Triplebiotic containing Bifidobacterium Lactis B420 and pasteurized Akkermansia Muciniphila on Hunger, Appetite and Cravings using the TFEQ-R18 Questionnaire over the course of 90 days. The TFEQ-R18 is a psychometric questionnaire that assesses eating behaviors and attitudes toward food. There are three dimensions: CR = conscious restraint, UE = uncontrolled eating, EE = emotional eating. High scores in UE or EE indicate an increased risk of overeating, weight gain, or eating disorders. A high score in CR shows a strong desire to restrict intake, but this is sometimes associated with episodes of disinhibition if the restriction fails.

    Time frame: From enrollment to the end of treatment at 12 weeks (90 days)

Other outcomes

  1. Assessment of appetite (e.g., number of meals) and food cravings (e.g., snacking or food preferences) in seven questions.

    How hungry were you today? How full do you feel right now? How many meals ? Did you think about your next meal when you finished your meal? How many craving did you have today? How strong is your desire to eat? How much food do you think you could eat right now?

    Time frame: From enrollment to the end of treatment at 12 weeks (90 days)

  2. Side effects experienced when taking the test product or placebo throughout the study (product tolerance)

    Expressed any of the following symptoms: headache(s), rash(es), cough, changes in appetite, or other.

    Time frame: The proportion of participants at day 14 (T1), day 30 (T2), day 60 (T3), day 90 (T4),

  3. patient satisfaction with product use and recommendation

    Evaluate the impact of UltraFlora Triplebiotic containing Bifidobacterium Lactis B420 and pasteurized Akkermansia Muciniphila after 90 days. Is satisfied with the intervention ? Would recommend the product ? Would purchase the product ?

    Time frame: The proportion of participants that at day 90 (T4):

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 6, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
