BT-11 Acts to Reduce Inflammation Through Multiple Mechanisms • BT-11 Multimodal MoA: BT-11 – Decreases the production of inflammatory mediators tied to IBD (TNF⍺, IFNγ, MCP1, IL-6, and IL-8) – Increases anti-inflammatory molecules in Tregs that protect LANCL2 from autoimmunity (IL-10, FOXP3) • BT-11 generates suppressive regulatory CD4+ T cells AC 5’AMP cAMP (Tregs) that restore and maintain immune tolerance in the GI tract – Decrease proliferation and differentiation of effector CD4+ T PKA ATP cells (Th1 and Th17) – Aid in epithelial cell and support the reduction of IL-8 and chemokine-dependent neutrophil influx Activates IL-10 & FOXP3 CREB Inhibits TNF-⍺ & IFN-γ Leber, A., et al. J Immunol, 2019. 11
Oral, gut-restricted small molecule BT-11 activates novel target LANCL2 Lanthionine Synthetase C-Like 2 • Multipronged mechanism of action targeting downstream known immunological targets tied to autoimmune diseases, including IBD. • BT-11 enhances CD25/STAT5 signaling to support the stable differentiation of regulatory CD4+ T cells with greater anti- inflammatory functionality. • BT-11 increases PDH activity, resulting in increased oxidative metabolism supporting FOXP3 stability. • BT-11 downregulates glycolytic pathways associated with TNF-a production and effector CD4+ T cells, including production of lactate and over-expression of ENO1. • BT-11 increases suppressive effects of Tregs due to enhanced immune checkpoint surface markers (LAG3 and PD-1).

BT-11 Phase 1 Dose-Finding Study in Healthy Volunteers Completed BT-11 Phase 1 Study (SAD/MAD) • Study Objective: To assess the safety and tolerability of BT-11 after single and multiple ascending oral dose administration in healthy volunteers, and to characterize the PK profile of BT-11 • Study Design: This is a double-blind, placebo-controlled, ascending dose, multicohort trial. The study was conducted with a single ascending dose (SAD) phase and a multiple ascending dose (MAD) phase • Population: Male or female normal healthy volunteers (NHV) aged 18 and over at the time of signing the informed consent, no prior use of any prescription medication • Study Dosing: – For SAD five dose target ranges of BT-11 (depending on body weight the doses in each cohort were 7.7 mg/kg; 25.0 mg/kg; 50.0 mg/kg; 75 mg/kg and 100.0 mg/kg) were evaluated – For MAD (once daily for 7 days), three dose target ranges of BT-11 (depending on body weight the doses in each cohort were 7.7 mg/kg; 50.0 mg/kg; and 100.0 mg/kg) were evaluated 17
Phase 1 Dose-Finding Study Establishes Positive Safety Profile Oral dosing of BT-11 does not induce systemic immunosuppression (observed with other IBD therapeutics) Single Ascending Dose Multiple Ascending Dose 18
BT-11 Reaches High Concentrations Within the Gut • BT-11 is observed in high concentrations in feces after both single- and seven-day dosing • GI concentrations are 6,000 times higher than Cmax levels found in plasma • Results confirm that BT-11 is stable within the gut and reaches the rectum in high concentration at proposed low dose level (7-14 mg/kg, total doses for the planned Phase 2 studies) 19
BT-11 Reduces Calprotectin in Stool, an Indicator of Inflammation in IBD • Fecal calprotectin is a biochemical measurement of the protein calprotectin in the stool • Elevated fecal calprotectin indicates the migration of neutrophils to the intestinal mucosa, which occurs during intestinal inflammation SAD: Calprotectin (day 2) MAD: Calprotectin (day 7) 20
