Bifidobacterium XLTG11 to support growth, immune health, and reduce allergies in infants at higher allergy risk

Official title: To Investigate the Effects of Bifidobacterium Animalis Subsp. Lactis XLTG11 on Growth and Development, Incidence of Allergy and Immune Function in Infants

Run by Universiti Sains Malaysia · NCT07490587 · Data updated 2026-11-12

This trial tests whether daily Bifidobacterium animalis subsp. lactis XLTG11 for 180 days can reduce allergic, respiratory, and gastrointestinal symptoms and change gut microbiome and immune markers in infants under 3 with higher allergy risk.

Is this trial a fit for you?

Likely a good fit

Healthy term infants and young children aged 0–3 years with an allergy risk score ≥6 who have not used antibiotics in the past month or probiotics in the past three months, and whose caregivers agree to fecal sample collection and to avoid additional Bifidobacterium supplements during the study.

Probably not a fit

Preterm or low birth weight infants, children who recently used antibiotics or probiotics, or those without an elevated allergy risk score are unlikely to benefit from this protocol's findings.

What this trial studies

This Phase 2, 180-day randomized, double-blind, placebo-controlled trial enrolls healthy term infants and young children under 3 years with an elevated allergy risk score. Participants receive daily Bifidobacterium animalis subsp. lactis XLTG11 or placebo and are monitored for incidence and day-level burden of allergic, respiratory, and gastrointestinal symptoms. Fecal samples collected before and after the intervention undergo shotgun metagenomic sequencing to profile microbiome composition and functional pathways (KEGG, COG, GO) and to measure mucosal immune markers (β-defensin 2, LL-37, calprotectin, sIgA). Clinical outcomes will be linked to microbial and immune changes to explore potential mechanisms of benefit.

Why it matters

Potential benefit: If successful, this could reduce how often and how severely high-risk infants experience allergic, respiratory, and gastrointestinal symptoms and strengthen mucosal immune defenses.

How similar studies have gone: Prior probiotic trials have shown mixed, sometimes modest benefits for eczema and some gastrointestinal symptoms, but evidence varies by strain and the specific XLTG11 strain has limited published data.
