Study summary

Study to demonstrate the efficacy of Probiotic ES1 in alleviating symptoms of gluten sensitivity in non-celiac gluten sensitive subjects exposed to a small, fixed amount of gluten.

Read the detailed description

This is a randomized, double-blind, placebo-controlled study. Sixty non-celiac gluten sensitive subjects will be randomized into one of two groups; Probiotic ES1 or placebo. For the duration of the study, subjects must adhere to a gluten-free diet, apart from a scheduled fixed gluten exposure of two slices of bread once daily. Subjects will be required to take 1 capsule before and after consuming the two slices of bread and score the severity of their symptoms in a diary provided for the duration of the study (7 days).

Study arms

  • Experimental
    Treatment (Probiotic ES1)

    Capsules containing 1 billion CFU of B. longum ES1 per capsule. One capsule taken before and after consuming 2 slices of bread for 7 days.

    Other: Probiotic ES1

  • Placebo comparator
    Placebo

    Capsules not containing the active ingredient B. longum ES1. One capsule taken before and after consuming 2 slices of bread for 7 days.

    Other: Placebo

Interventions

  • OtherProbiotic ES1

    B. longum ES1 is formulated for oral use as Glutagest. Each capsule contains 1 billion CFU of B. longum. The capsules are off-white in color and cylindrical in shape with approximate dimensions of 19 mm x 6.63 mm and a weight of 500 mg. Non-medicinal ingredients consist of the common excipients filler rice maltodextrin, lubricant stearic acid, and encapsulating agent vegetable cellulose.

    Also known as: Glutagest

  • OtherPlacebo

    The placebo is composed of the same non-medicinal ingredients as the investigational product (IP) (i.e. rice maltodextrin, stearic acid, and vegetable cellulose) but it does not contain the active ingredient B. longum ES1. The placebo is designed to resemble the IP in terms of physical appearance.
