  • Ages 18 to 65 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Willing and able to give written informed consent for participation in the study.
  • Healthy male or female subject aged 18-65 years inclusive.
  • Body Mass Index (BMI) ≥ 18.0 and ≤ 32.0 kg/m2.
  • Clinically normal medical history, physical findings, vital signs, and laboratory values at the time of screening, as judged by the Investigator.
  • Female subjects of child bearing potential must practice abstinence (only allowed when this is the preferred and usual lifestyle of the subject) or must agree to use a highly effective method of contraception with a failure rate of < 1% to prevent pregnancy (combined [oestrogen and progestogen containing] hormonal contraception associated with inhibition of ovulation [oral, intravaginal, transdermal], progestogen-only hormonal contraception associated with inhibition of ovulation [oral, injectable, implantable], intrauterine device [IUD]or intrauterine hormone-releasing system [IUS]) from at least 4 weeks prior to dose to 4 weeks after last dose. Female subjects of non-childbearing potential are defined as pre-menopausal females who are sterilised (tubal ligation or permanent bilateral occlusion of fallopian tubes); or post-menopausal defined as 12 months of amenorrhea (in questionable cases a blood sample with simultaneous detection of follicle stimulating hormone [FSH] 25-140 IE/L is confirmatory).

Who cannot join

  • History of or ongoing clinically significant disease that, in the opinion of the Investigator, may either put the subject at risk because of participation in the study, or influence the results or the subject's ability to participate in the study.
  • Any clinically significant illness, medical/surgical procedure or trauma within 4 weeks of the first administration of the IP.
  • Malignancy within the past 5 years with the exception of in situ removal of basal cell carcinoma.

Show all 20Show fewer

  • Regular use of any prescribed or non-prescribed medication including antacids and analgesics within 2 weeks prior to the first administration of IP, at the discretion of the Investigator.
  • Any use of antibiotics (except local treatment, e.g., eye drops) within 2 weeks prior to the first administration of IP.

Foods that contain microorganisms, live or dead, that do not confer any health benefit on the host, e.g., regular yoghurt, are allowed.
  • Planned treatment or treatment with an investigational drug within 3 months prior to Day 1. Subjects consented and screened but not dosed in previous clinical studies are not excluded.
  • Current smokers or users of nicotine products. Irregular use of nicotine (e.g., smoking, snuffing, chewing tobacco) less than 3 times per week is allowed before the screening visit.
  • Positive screen for drugs of abuse or alcohol at screening or on admission to the unit prior to administration of the IP. Drugs of abuse and alcohol will also be screened during the study (refer to Section 9.6.1).

About this study

Official title: A Double-blind, Randomised, Placebo-controlled, Parallel-group Study Evaluating the Safety and Tolerability of Limosilactobacillus Reuteri Administered to Healthy Volunteers.

The rationale for the current study is to initially evaluate the safety and tolerability of a novel strain of the probiotic Limosilactobacillus reuteri (L. reuteri) in healthy volunteers.

Read the detailed description

Probiotics are live microorganisms, which when administered in adequate amounts, confer a health benefit on the host. Probiotics have been studied for decades for their potential health benefits of non-pathogenic microorganisms. The species Limosilactobacillus reuteri (L. reuteri), formerly Lactobacillus reuteri, is currently used in probiotic products.

The design of the study is based on the aim to study the safety and tolerability of a novel strain of the probiotic Limosilactobacillus reuteri (L. reuteri) in a limited number of healthy volunteers.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. To evaluate the incidence of treatment emergency adverse events (safety and tolerability).

    The product to be investigated is a probiotic product and not an investigational medicinal product. However, the procedures for monitoring, collecting and reporting of AEs will be the same as for an investigational medicinal product.

    Vital signs, systolic and diastolic blood pressure and pulse will be measured. Vital signs will be judged as normal, abnormal, not clinically significant or abnormal, clinically significant.

    Safety laboratory parameters, blood samples for analysis of clinical chemistry and haematology will be analysed by routine analytical methods.

    Urine drug screen and urine pregnancy test will be performed. Abnormal values assessed by the Investigator as clinically significant will be reported as AEs. If an abnormal value is associated with corresponding clinical signs or symptoms, the sign/symptoms should be reported as the AE.

    Measured: 28 days

Secondary outcomes (1)
  1. To evaluate tolerability in terms of gastrointestinal symptoms

    To evaluate gastrointestinal symptoms by using Gastrointestinal Symptom Rating Scale (GSRS) over the last week. The questionnaire will be answered by the subjects at visit 2 to 5.

    The Gastrointestinal Symptom Rating Scale is a disease-specific instrument. The 15 items are combined into five clusters: Reflux, Abdominal pain, Indigestion, Diarrhoea and Constipation. The subjects are asked to numerically score their subjective symptoms 1-7. Thus the lowest score is 15 and the highest is105. The higher score the worse outcome. The reliability and validity of the Gastrointestinal Symptom Rating Scale are well-documented, and norm values for a general population are available.

    The data collected using the Gastrointestinal Symptom Rating Scale does not constitute AEs and will not be reported as numerical results. Accordingly, no causality assessment by the Investigator will be performed for the Gastrointestinal Symptom Rating Scale questionnaire.

    Measured: 28 days

Questions about this trial

What is this clinical trial studying?

A study testing Probiotic in people with Healthy Volunteers and Tolerability, run by BioGaia AB at 2 sites in Sweden.

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 5 inclusion and 20 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 11 Feb 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Sweden. 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?

To evaluate the incidence of treatment emergency adverse events (safety and tolerability). (time frame: 28 days). 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 11 Feb 2022.
