IMM - 124E Revolutionary Treatment for NASH

NASH (Non - Alcoholic Fatty Liver) Pathophysiology 11 NASH – Pathophysiology • Blood derived antigens (including circulating LPS) determines tolerance vs. inflammation • Kupffer cells play a key role in liver inflammation and fibrosis • Tregs hold a key role in tolerance (homeostasis) • Much like hepatic tolerance the gut immune system can promote anti - inflammatory effect Source: Adapted from Cohen - Naftaly; Scott L. Friedman, 2011

IMM - 124E in NASH (Non - Alcoholic Fatty Liver ) 12 • Broad anti - inflammatory mechanism of action - Targeted LPS antibodies - Upstream Effect: LPS - TLR4 pathway - Downstream: Anti - inflammatory through both innate and adaptive immune systems (e.g ., the induction of regulatory T - cells to control and inhibit excess inflammation) • Strong anti - fibrotic effect demonstrated with CCl4 model • Unique c ompetitive profile due to safety/MOA: - Addresses multi - factorial nature of NASH - Potential for broad combination use - Safety profile supporting of long - term chronic use - Potential to expand to mild/moderate populations • Market exclusivity (biologics; high barriers to generic biosimilar entry)

Cirrhosis 1.2 M people F4 IMM - 124E – Uniquely Positioned to Address Large Unmet Need of $35B Market (2030) 13 NAFLD Up to 145M People • No regulatory pathway currently exists for NAFLD • Drug would need to be extremely safe to be considered for trial / approval • NAFLD not available to current competitors due to safety profile • Up to 50% of the US population are thought to have NAFLD NASH 25M People F0 F 1 F2 F3 17M People 8M People Intercept (OCA) Tobira (CCR2/CCR5) Galmed ( Aramchol ) Genfit ( Elafibranor ) Galectin (GR - MD - 02) • Only asset in development that, due to its safety profile: - C an potentially target all spectrum of the disease including mild/moderate patients - Likely can be used in combination with any other agents currently in development - No safety concerns to date that could limit chronic / long - term use IMM - 124 E

IMM - 124E: Fatty - Liver Portfolio – 3 Phase 2 Trials 14 Three Ongoing Phase 2 Programs: NASH, ASH and Pediatric NAFLD NASH • Lead Principal Investigator: Arun Sanyal; Former President of AASLD (American Association for the Study of Liver Diseases) and current Chair of the Liver Study Section at the NIH (National Institute of Health) • Multi - center, double - blinded, placebo controlled trial; 25 sites running in US, Australia and Israel • Fully recruited: 134 patients with biopsy proven NASH • Primary endpoint: changes in liver fat content confirmed by MRI; changes in ALT (liver enzymes) • 3 arms: placebo, high dose and low dose • Timing: topline results expected by 4Q 2017 ASH • NIH funded; sponsored by University of Virginia • Expected enrollment: 66 patients • Endpoint: ALT • Timing: topline results expected in 2018 Pediatric NAFLD • NIH funded; sponsored by Emory University • Expected enrollment: 40 patients • Endpoint: ALT; 3 months treatment • Timing: topline results expected in 1H 2018

IMM - 529 Neutralizing Clostridium difficile , but Sparing the Microbiome

IMM - 529 in Clostridium d ifficile Infection (CDI ) 24 • Biologic with unique triple mechanism of action - Antibodies neutralize the toxin B, the spores and the vegetative cells • Potential to redefine the standard - of - care (SOC) therapy for CDI - Current antibiotic treatments exacerbate recurrence - IMM - 529 stops virulence, without impacting the microbiome - Compelling data in all three phases of the disease including ( 1 ) prevention of primary disease, ( 2 ) treatment of primary disease and ( 3 ) prevention of recurrence - Orally administrated, safe • > 70 % survival rate in CDI mice treated with IMM - 529 vs. < 7 % survival rate in control groups • Potential orphan disease designation; potential breakthrough / fast track designations • Market exclusivity (biologics; high barriers to generic biosimilar entry)

IMM - 529 for the Treatment of CDI 25 Market Opportunity • Therapeutic market is expected to grow from S$ 356.3 million in 2014 to over $ 1.5 billion by 2024 – CAGR 15 % • Nearly 30 , 000 patients die each year from C. difficile infections (US) • Potential orphan disease ( 7 years market exclusivity and premium pricing) Unmet Need • Vancomycin and metronidazole are the current standard of care, accounting for 80 % of patient share (US) • However, therapies are plagued by significant CDI recurrences ( 1 st relapse: 25 %; 2 nd: 40 %; 3 rd: 50 %) underscoring need for new treatments • There is also growing resistance to vancomycin treatment IMM - 529 Positioning • Highly differentiated – Neutralizes C. difficile but does not impact microbiome • Only asset that targets not only toxin B but also the spores and the vegetative cells responsible for recurrence • Can be used in combination with standard of care • Targets many isolates Sources: GlobalData, Decision Resources, CDC

Triple Action MOA Neutralizing C. difficile; Sparing the Microbiome 26 Spores – Infectious Particles IMM - 529 antibodies bind to multiple epitopes on surface antigens on spores and prevent adherence to ho st cells and limit germination. Heat, ethanol and UV resistant. Survive gastric acid, adhere to cells in the colon and germinate. Vegetative Cells IMM - 529 antibodies bind to multiple epitopes on the surface layer proteins (SLP) on vegetative cells and limit colonization. Fimbriae and other surface layer proteins (SLP) contribute to bacterial colonization. Fimbriae are used to adhere to other bacteria and to host cells and is one of the primary mechanisms of virulence Toxin B IMM - 529 antibodies bind to multiple epitopes effectively neutralize toxin B, inhibiting toxin mediated epithelial cell apoptosis and limit toxin translocation into the systemic circulation and inflammatory cascades. Toxin B is essential for virulence. Toxin B disrupt the cytoskeleton and tight junctions of intestinal epithelial cells. 3 1 2
