What this trial studies

This clinical trial is a single-center, randomized, double-blind, placebo-controlled evaluation of INF108F, a probiotic treatment, in breastfed infants diagnosed with food protein induced allergic proctocolitis (FPIAP). Over a 4-week period, the study will assess various outcomes including the presence of blood in stool, infant stooling patterns, sleep quality, feeding habits, and growth metrics. Safety will be monitored through the collection of adverse events during the trial. The goal is to determine the efficacy of INF108F in improving symptoms associated with FPIAP.

Who should consider this trial

Good fit: Ideal candidates for this study are breastfed infants aged 1 to 90 days with a documented diagnosis of FPIAP.

Not a fit: Infants who are exclusively formula-fed or have other severe medical complications may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the health and well-being of infants suffering from FPIAP.

How similar studies have performed: While this approach is novel in the context of FPIAP, similar probiotic interventions have shown promise in other gastrointestinal conditions.
