A Synergistic Multistrain Live Biotherapeutic Product for the Prevention and Treatment of Necrotizing Enterocolitis
Amount: $300,000 Topic: NIAID
ABSTRACT Necrotizing Enterocolitis (NEC) is an inflammatory disease of the intestines that primarily afflicts preterm infants. In severe cases, intestinal tissue necrosis can lead to perforation, sepsis, and death. NEC is estimated to develop in 7% of very low birth weight infants and carries an associated mortality rate of 30-50%, making it one of the leading causes of death in preterm infants. To prevent colonization and infection by opportunistic bacterial pathogens, preterm infants are commonly administered antibiotics. While antibiotics remain effective for reducing NEC-associated infections and improving outcomes, their broad-spectrum effects can disrupt intestinal colonization by protective bacterial species, leave the intestinal tract open to reinfection, and drive antibiotic resistance in opportunistic pathogens. An updated approach to NEC management that leverages protective bacteria to strengthen the developing gut microbiota after antibiotic treatment is well overdue. At Siolta Therapeutics, we are developing STMC-106, a multistrain Live Biotherapeutic Product (LBP) to prevent and treat NEC. Unlike probiotic products, we will develop STMC-106 under an IND to meet the safety, efficacy, and quality standards required for approval as a biologic product by the FDA. We hypothesize that treatment with STMC-106, a rationally designed LBP containing multiple synergistic bacterial strains as active ingredients, will reduce both opportunistic pathogen burden and intestinal inflammation to improve clinical outcomes in NEC. To test this hypothesis, in Specific Aim 1 we will identify combinations of therapeutic candidate bacteria for inclusion in STMC-106 that act synergistically to enhance NEC therapeutic potential in vitro. Candidate consortia that display growth of all active partner strains on human breastmilk through efficient metabolic cross-feeding will be screened to identify two top-performing consortia that inhibit inflammatory signaling and enhance intestinal epithelial barrier function in vitro. In our Specific Aim 2, we will evaluate the in vivo efficacy of two top-performing STMC-106 formulations in a neonatal piglet model of NEC. We will test the efficacy of these two rationally designed bacterial consortia in both a prevention and treatment model design. Efficacy will be evaluated based on the ability of the candidate interventions to reduce intestinal inflammation and tissue necrosis and the burden of opportunistic pathogens in the gut lumen. Our long-term objective is the clinical development and regulatory approval of STMC-106, an LBP designed for preventing and treating NEC in high-risk preterm infants. Successful development of this LBP could save thousands of preterm infants from this deadly illness each year.

Anaerobic Manufacturing and Molecular Analytical Process Optimization to Support Clinical Development of Live Biotherapeutic Products
Amount: $2,921,132 Topic: NIAID
ABSTRACT Allergic diseases including atopic dermatitis, food allergy, and allergic asthma represent a global health problem that disproportionately impacts children. Surprisingly, there are no approved approaches to prevent the development of these diseases in at-risk individuals, resulting in chronic morbidity and economic burden. The management of asthma, for example, carries a steep cost burden of billions of dollars per year in the US alone, of which nearly 20 billion is spent on standard of care treatments with variable efficacy. Food allergy management is generally limited to allergen avoidance and rescue from severe acute anaphylaxis. There is a crucial need to develop innovative strategies to prevent the onset of these Type 1 allergic diseases rather than treating their symptoms. A preventative approach targeting at-risk individuals could significantly reduce the morbidity and healthcare burden associated with these increasingly common conditions. Studies confirm the link between gut microbiota development, immunological training, and allergic disease onset in childhood, and it is now clear that allergic disease risk is associated with aberrant microbial exposures over the first year of life. Longitudinal gut microbiota profiling studies in infants and children show that a loss of specific immunomodulatory commensal bacteria, and their metabolic networks, precedes allergic disease development. Using infant gut microbiota data sets and in vivo allergic disease models, Siolta Therapeutics has designed a live biotherapeutic product (LBP), STMC-103H, to stimulate tolerant immunological development and prevent allergic disease onset in at-risk individuals. STMC-103H contains three distinct active ingredient bacteria isolated from healthy human stool. Siolta has performed extensive cGMP manufacturing development, including formulation, process, and analytical method development, to support Phase 1 and Phase 2 clinical trials of STMC-103H under an IND with the FDA. In this project, we will build on our previous STMC-103H drug product development to improve the stability, potency, and characterization approaches for late-stage clinical trials and subsequent commercialization. Success of this project will directly support the regulatory and commercial development of STMC-103H. Indirectly, this work will improve the manufacturing and clinical development of diverse candidate LBPs containing sensitive live bacteria with high therapeutic potential. Siolta will also seek to license novel manufacturing approaches to other LBP developers.
