## Summary

Infant Bacterial Therapeutics (IBT) is developing live biotherapeutic Lactobacillus reuteri DSM17938 for necrotizing enterocolitis prevention in premature infants, with Phase 3 trial results expected in 2026.

## Company Overview

Infant Bacterial Therapeutics (IBT) is a Swedish biopharma company developing Lactobacillus reuteri DSM17938 — a probiotic bacterial strain — as a regulated drug (live biotherapeutic product) to prevent necrotizing enterocolitis (NEC) in premature infants. NEC is a devastating gastrointestinal emergency affecting 1–7% of premature newborns, with 30% mortality and severe long-term outcomes in survivors. No approved preventive treatments exist, despite decades of evidence suggesting certain probiotic strains reduce NEC incidence.

IBT's approach treats a well-characterized probiotic strain as a pharmaceutical product with rigorous GMP manufacturing, safety testing, and clinical development — a regulatory path enabled by the FDA and EMA's live biotherapeutic framework. The company's Phase 3 PROPREMS-3 trial across 40+ neonatal intensive care units is among the largest neonatal probiotic trials ever conducted, with results expected in 2026.

Founded in 2014 and listed on Nasdaq First North in Stockholm, IBT has partnerships with major neonatal nutrition companies and has raised significant funding to complete the pivotal trial. Regulatory approval would create the first FDA/EMA-approved preventive therapy for NEC, addressing a critical unmet need in neonatal intensive care.

## Frequently Asked Questions

### What disease is Infant Bacterial Therapeutics targeting?
IBT targets necrotizing enterocolitis (NEC), a devastating gastrointestinal emergency affecting 1–7% of premature newborns with 30% mortality and no currently approved preventive treatment.

### What is IBT's approach?
IBT develops Lactobacillus reuteri DSM17938 as a regulated live biotherapeutic product with pharmaceutical-grade manufacturing and clinical rigor — treating an established probiotic strain as a drug rather than a supplement.

### When will IBT's Phase 3 trial read out?
IBT's PROPREMS-3 Phase 3 trial across 40+ NICUs is expected to report results in 2026, potentially enabling the first FDA/EMA approval for NEC prevention.

### What is IBT's lead clinical candidate?
IBT's lead candidate IBP-9414 is a live biotherapeutic product (LBP) — a specific strain of Lactobacillus reuteri — designed to prevent necrotizing enterocolitis (NEC) in premature infants. IBP-9414 is administered as oral drops starting within the first days of life, colonizing the preterm infant gut and outcompeting pathogenic bacteria that trigger the inflammatory cascade leading to NEC.

### What regulatory milestones has IBT achieved?
IBP-9414 has FDA Breakthrough Therapy Designation and is in a Phase 3 pivotal trial (PROPREVENT study) with results expected in 2025-2026. Breakthrough Therapy Designation accelerates FDA review timelines and increases FDA interaction during development — a significant regulatory advantage in a disease with high unmet need where no FDA-approved preventive therapy currently exists.

### What is necrotizing enterocolitis and why is there unmet need?
NEC is a devastating gastrointestinal emergency affecting premature infants where intestinal tissue becomes inflamed and dies. It affects approximately 5-7% of very premature infants (under 28 weeks gestation) and carries 15-30% mortality; survivors often face severe long-term complications including short bowel syndrome requiring lifelong parenteral nutrition. Despite decades of research, there is no FDA-approved preventive therapy — making NEC one of neonatology's largest unmet needs.

### What is the market opportunity for NEC prevention?
Approximately 30,000 extremely premature infants are born annually in the US who are at significant NEC risk. At a pricing comparable to other neonatal biologics ($50,000-150,000 per NICU course), the US market opportunity alone is $1.5-4.5 billion annually. Ex-US markets in Europe, Japan, and emerging economies with growing NICU infrastructure add substantial additional opportunity. An FDA-approved NEC preventive would face minimal competition given the absence of existing approved therapies.

### How does IBP-9414 compare to existing clinical practice?
Many NICUs already use off-label probiotics to reduce NEC risk based on evidence from smaller trials; however, these are unregulated dietary supplements with inconsistent formulations and no FDA-validated efficacy data. IBP-9414 is a pharmaceutical-grade, single-strain biotherapeutic with rigorously controlled manufacturing, Phase 3 clinical evidence, and FDA regulatory oversight — addressing the quality and efficacy certainty gaps that have prevented payers from covering and physicians from confidently recommending probiotic use.
