About this study

Official title: A Randomized, Double-blind, Placebo-controlled Intervention Study to Assess the Safety and Tolerance Effect of Three Probiotic Strains in Infants

Study to evaluate the safety and tolerance of three probiotic bacteria intake by healthy infants. Participants are divided at random and unknown to the researchers, in four groups, three of which receive one of three probiotic bacteria while the fourth group receives placebo product.

Read the detailed description

Subjects' parents or legal tutors will be contacted for voluntary participation and a written informed consent will be obtained.

The study visits will take place either in the hospital or primary health center.

During Visit 1, inclusion in- and exclusion criteria will be checked and information on demographic profile, subject characteristics, feeding option, relevant medical history, medication and nutritional supplements will be recorded. Weight and length and head circumference measurements of the infant will be made. The researcher will explain to the parents that during the first 2 weeks of participation in the study the infant must not intake any probiotic supplements (run-in ). Parents will be instructed to collect and send and/or store fecal and urine samples before starting the study. In addition they will be instructed to collect and send and/or store fecal and urine samples after the initial run-in period (2 weeks), after the product intake period (8 weeks) and after the final wash out period (2 weeks).

During Visit 2, subjects will be randomly allocated to receive either one of the test products or the placebo. Body weight and length will be measure. The researcher will review with the parents the study diary in detail, how to record data on gastrointestinal tolerance, stool frequency and stool characteristics, respiratory symptoms, diagnosed infections, sleeping and crying habits, changes in sleeping pattern, fever episodes, unscheduled visits resulting from suspected infection or a health problem and antibiotic prescription. The researcher will explain the procedure of administering the study product to the infant and anticipated phone calls. The parents will be instructed to start intake of the product as soon as possible after the collection of fecal and urine samples.

During product intake period (8 weeks) subject's parents will be called weekly by someone from the Study Team (Phone call 1, 2, 3, 4, 5, 6, 7). During the phone call relevant data related to possible Adverse Events (AEs) or Serious Adverse Events (SAEs) will be collected. Parents will be asked about infant's well-being (fever episodes, rashes, diarrhea, visits to the doctor, antibiotic prescription, etc.). Issues regarding diary completion, if any, will be discussed. During the Phone call 7 parents will be instructed to collect and send and/or store fecal and urine samples in one of the days prior to the third visit.

At the third visit (Visit 3, 8 weeks after product intake period), body weight and length will be measured and relevant data will be collected with respect to health and well-being aspect of the infant and AE or SAE (fever episodes, rashes, diarrhea, visits to the doctor, antibiotic prescription, etc.). Completed diaries and fecal and urine samples will be collected. Parents will be explained that for the last 2 weeks of participation in the study their infants could not intake any probiotic supplement (final wash out period). Parents will be instructed to collect and send and/or store fecal and urine samples in one of the days prior to the next visit (Visit 4).

During visit 4, after the final wash out period, body weight and length will be measured and relevant data will be collected with respect to health and well-being aspect of the infant and AEs or SAEs (fever episodes, rashes, diarrhea, visits to the doctor, antibiotic prescription, etc.). Completed diaries and samples will be collected.

What is being measured

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

  1. Safety and tolerance will be evaluated according to infant growth (weight, height and head circumference)

    growth will be evaluated considering weight, height and head circumference, at four different time points during study: 1st measure will be at screening visit (visit 1/week 0), 2nd measure will be after the run-in period and before starting intervention (visit 2/ week 2), 3rd measure will be after the eight weeks of intervention (visit 3/ week 10) and the 4th measure will be two weeks later (visit 4/week 12).

    Measured: 12 weeks

  2. Adverse Event and/or Serious Adverse Event

    Adverse Event and/or Serious Adverse Event will be recorded daily by parents and notified to investigator within 24hrs., in particular gastro-intestinal symptoms, fever and rashes.

    Measured: 10 weeks

  3. Fecal characteristics

    Fecal characteristics (stool frequency, stool consistency, stool amount and stool color) will be recorded daily by parents according to the "Amsterdam scale" and notified weekly to investigators.

    Measured: 10 weeks

  4. Use of medication

    Medication used (antibiotics, etc) will be recorded daily by parents and notified weekly to investigators.

    Measured: 12 weeks

Secondary outcomes (4)
  1. Urine concentration of D-lactic acid.

    D-lactic acid will be measured in urine samples at 4 different time points (weeks 0, 2, 10 and 12).

    Measured: 12 weeks

  2. Changes in sleep and crying patterns

    Changes in sleep and crying patterns will be recorded daily by parents and notified weekly to investigators.

    Measured: 10 weeks

  3. Immune compounds in fecal samples

    Immunoglobulins (Ig) A, G1, G2, G3, G4 and M, cytokines, chemokines and growth factors such as interleukins (IL) 1β, 2, 4, 5, 6, 7, 8, 10, 12, 13, and 17, interferon-γ (INF-γ), tumor necrosis factor-α (TNF-α), growth related oncogene-α (GRO-α), macrophages chemoattractant protein-1 (MCP-1), macrophages inflammatory protein-1β (MIP-1β), granulocyte-colony stimulating factor (G-CSF), granulocyte-macrophages colony stimulating factor (GM-CSF) and Calprotectin concentrations will be measured at two time points, before and after the study probiotic intake (weeks 0 and 10).

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Bifidobacterium longum ssp infantis R0033, Lactobacillus helveticus R0052 and Bifidobacterium bifidum R0071 in people with Body Weight and Body Height, run by ProbiSearch SL at 1 site in Spain.

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 2 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: finished, as of the sponsor's last update on 14 Dec 2016. 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 Spain. 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?

Safety and tolerance will be evaluated according to infant growth (weight, height and head circumference) (time frame: 12 weeks). The study lists 4 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 14 Dec 2016.
