Lm Technology Overview: Harnessing Unique Life Cycle of Lm in APCs Lm-LLO and Tumor Associated Antigen (TAA) presented and taken up by dendritic cells (antigen presenting cells or APCs) 2 Some Lm-LLO is killed and degraded within the phagolysosome Dendritic cells activated to generate an immune response through both the MHC I and MHC II pathways Robust T-cell response generated toward antigen secreted by Lm-LLO and redirected against tumors expressing the same TAA "Perceived" acute infection stimulates a strong innate immune response through multiple pathways (e.g. STING) Over-rides checkpoint inhibitors and negative regulators of cellular immunity 1 Lm-LLO is phagocytosed by APC 3 Some Lm-LLO escapes the phagolysosome and enters the cytosol 4 tllo-taa fusion protein is degraded by proteasomes into peptides for presentation to the MHC class I pathway 5 Peptide-MHC complexes on the APC simulate CD4+ (MHC II) and CD8+ (MHC I) T-cells APC, antigen presenting cell; Lm, Listeria monocytogenes; MHC, major histocompatibility complex; TAA, tumor-associated antigen; tllo, truncated listeriolysin O 6
Targeting Neoepitopes Is the Next Step in the Evolution of Cancer Immunotherapy Why does cancer develop neoepitopes? Tumors develop because of mutations in genes coding for key regulatory and functional proteins Expression of mutated proteins causes aberrant cellular functions that result in malignancy, and malignant cells survive by avoiding the immune system Normal peptides are weakly immunogenic (central tolerance deletes high avidity clones), but mutated cancer proteins are completely different from normal cells (neoepitopes) How can this be used to attack cancer? Immunotherapies work by activating the patient s immune system to target epitopes in cancer cells High avidity cytotoxic T-cells can be generated against neoepitopes Checkpoint inhibition appears to work by enabling pre-existing T cells to respond against neoepitopes, expand, and become tumoricidal Immunizing patients against their own neoepitopes with an attenuated live vector will generate or enhance T-cell responses against neoepitopes Because the T cell responses are only directed against the mutated neoepitopes, and there is no systemic blockade of tolerance, there should be no off-target toxicity and few AEs 7
Targeting Neoepitopes with Lm Technology Advantages for Personalized Immunotherapy Lm Technology has advantages for targeting neoepitopes Bandwidth for example, 5 constructs can present >250 tumor neoepitopes to T-cells, obviating the need for a predictive algorithm Feasibility affordable and easy to manufacture intime for patient treatment (compare to autologous therapy) tllo TAA fusion protein is a synthetic peptide presenting multiple neoepitopes secreted into the cytoplasm of the APC 80-100 plasmid copies per bacteria Payload for 25-50 neoepitopes per construct up to ~2k+ amino acids Multiple constructs can be administered for larger numbers of neoepitopes Activates other immune pathways (TLRs, PAMP, STING, DAMP, NOD1, NOD2, CpG) Treatments can be given repeatedly without neutralizing antibodies Generates strong innate and adaptive T cell response, even to lower avidity epitopes Decreases Tregs and MDSCs in the tumor microenvironment TAA, tumor-associated antigen 8
ADXS-NEO Start to Finish How does it work? Academic or Commercial Massively Parallel Sequencing Advaxis Immunotherapies Patient s Hospital or Treating Institution Sequencing to identify nonsynonymous mutations Advaxis designs vector based on neoepitopes Treat patient with personalized immunotherapy vector based on his/her neoepitopes Identify neoepitopes DNA synthesis molecular cloning into plasmids Multiple cycles of treatment and combination with RT, PD-1, co-stims possible Transfection into personalized vector, QA/QC OK Ship to patient s institution Time from biopsy to infusion administration = ~6 weeks 9
ADXS-NEO: Next Steps Pre-IND meeting completed Planning to file IND in 2016 Continue building collaborations to drive ADXS-NEO forward as rapidly as possible MINE Collaboration with Memorial Sloan Kettering Cancer Center will focus on preclinical and clinical development of neoepitope-based Lm treatments Completion of in-house manufacturing facility in 2016 to enable clinical supply 10

29 ENROLLED Axalimogene Filolisbac: Open Label 2-Stage Phase 2 Study In Recurrent Cervical Cancer (GOG 0265) Stage 1 Data Presented at American Gynecological & Obstetrical Society (AGOS) 2015 3 did not receive therapy 26 treated 10 patients achieved required 12-month survival 12-month survival rate = 38.5% Study exceeded required 20.0% efficacy threshold and predetermined safety criteria and has proceeded to Stage 2 with additional enrollment of 37 patients No approved therapy following failure of first-line treatment, with historical survival only 4-7 months 1 Safety Summary: Axalimogene filolisbac was well-tolerated, with Grade 1-2 fatigue, chills, and fever the most commonly reported AEs; six patients experienced a treatment-related Grade 3 or Grade 4 AE, which was considered possibly related to axalimogene filolisbac. The adverse events observed in the first stage of the study have been consistent with those reported in other clinical trials with axalimogene filolisbac. 1 Monk BJ, et al.
