Inclusion criteria

between 18.5 and 24.9 kg/m2 inclusive Lactose intolerant

The following criteria need to be checked at visit 2:

  • Lactose intolerance confirmed by positive Hydrogen Breath Test (HBT) (i.e. if there are two or more samples with hydrogen level > 20 ppm increase compared to baseline sample between 90 mins and 240 min sampling time point).
  • At least one sample with hydrogen level > 20 ppm increase compared to baseline between 90 mins and 180 mins sampling time point.

Exclusion criteria

Exclusion Criteria:

History of gastrointestinal disorders Current illness which could interfere with the study (e.g. diarrhea, regurgitation) Any history of cow's milk protein allergy or known allergy to galacto-oligosaccharides Any current participation or within 8 weeks of study start, in any other study involving or marketed products, any medical procedures, or any surgical methods.

Any antibiotic, laxative or colonic cleansing treatments within 4 weeks of study start Any administration of probiotic in the 1 week prior to study start Investigator's uncertainty about willingness or ability of subject to comply with protocol requirements

The following criteria need to be checked at visit 2:

  • Level of hydrogen > 20 ppm in the baseline breath sample.
  • An early peak of hydrogen (i.e. hydrogen level > 20 ppm increase compared to baseline value) in the first 60 minutes after ingestion of the study products.
Terms in these criteria, in plain language(2)

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.

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.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. Log of First Postprandial Peak Change of Hydrogen Concentration

    This is measured as the log of the first change \>20ppm peak value compared to baseline between 90 minutes and 240 minutes. If there was no change \>20ppm at all between 90 minutes and 240 minutes, it is the maximum change compared to baseline in that interval

    Time frame: Postprandial peak hydrogen in breath within 4 hours after ingestion of study product; samples taken at 30 minute intervals for 4 hours, i.e. at 90, 120, 150, 180, 210 and 240 minutes at Visits 3 and 4

  2. Log of Maximum Postprandial Change in Hydrogen Concentration

    This is measured as the maximum change in postprandial hydrogen concentration (ppm) compared to baseline between 90 minutes and 240 minutes

    Time frame: Maximum postprandial hydrogen in breath within 4 hours after ingestion of study product; samples taken at 30 minute intervals for 4 hours, i.e. at 90, 120, 150, 180, 210 and 240 minutes at Visits 3 and 4

Secondary outcomes

  1. Square Root of Postprandial Incremental Area Under Curve (iAUC) of Hydrogen Concentration From 30 Minutes to 240 Minutes

    The iAUC of hydrogen concentration from 30 to 240 minute sampling time points is calculated with the triangular rule (reference: Wolever TM. Effect of blood sampling schedule and method of calculating the area under the curve on validity and precision of glycaemic index values. Br J Nutr. 2004 Feb;91(2):295-301). The square root of the iAUC is then taken for the outcome measure

    Time frame: Hydrogen in breath within 4 hours after ingestion of study product; samples taken at 30 minute intervals for 4 hours, i.e. at 30, 60, 90, 120, 150, 180, 210 and 240 minutes at Visits 3 and 4

The record gives a start of Nov 2015, a primary completion of Jun 2016 and a completion of Jun 2016. It does not say whether these dates are actual or estimated.

Results were first posted in Mar 2020, 3 years 9 months after primary completion.

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 Mar 18, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
