Overview
Brief Summary
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.
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.
Investigators
Eligibility Criteria
Inclusion Criteria
- •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/m
- •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).
Exclusion Criteria
- •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.
- •Any planned major surgery within the duration of the study.
- •Any positive result on screening for serum hepatitis B surface antigen, hepatitis C antibodies or HIV.
- •History of severe allergy/hypersensitivity or ongoing allergy/hypersensitivity, as judged by the Investigator, or history of hypersensitivity to Lactobacillus probiotic treatment.
- •History of, or ongoing GI disorder, including but not limited to irritable bowel syndrome (IBS), constipation, loose stools or excess gas which, in the discretion of the Investigator, may influence the results or the subject's ability to participate in the study.
- •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.
- •Regular use of supplements, i.e., tablets, drops, capsules etc, that contain L. reuteri or any other probiotics within 2 weeks prior to the first administration of IP.
Outcomes
Primary Outcomes
To evaluate the incidence of treatment emergency adverse events (safety and tolerability).
Time Frame: 28 days
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.
Secondary Outcomes
- To evaluate tolerability in terms of gastrointestinal symptoms(28 days)
