3 LTX-315 – first-in-class oncolytic peptide immunotherapy • LTX-315 makes cold tumors hot and responsive to immune checkpoint Inhibitors (ICIs) by releasing Unique an extended range of tumor specific antigens product • Strong pre-clinical anticancer activity and increased efficacy with ICIs • Ideal combination partner for ICIs – potential to augment efficacy without adding significant toxicity • Potential treatment in multiple, large indications Block buster • Targeting malignant melanoma, breast cancer and follow-on indications potential • Blockbuster potential with sales exceeding 1 billion USD • Clinical evidence of anti-tumor and immune effects presented at ECC2015 • Clinical evidence Stable disease (irRC response criteria) – 50% (8/16) median duration of stable disease: 14 weeks • Significant infiltration of CD8+ T-cells – 76% (13/17) patients
4 The Nordic landscape of immuno oncology The competitive landscape is rapidly changing, with several different compounds currently being tested in target indications The companies below have developed different technologies to fight cancer – the real race is abut finding successful combinations with checkpoint inhibitors which is expected to result in high deal-making activity Nature of therapy Clinical phase Lytix Biopharma Oncolytic Peptide Phase I Alligator Bioscience Antibody-based Phase I Immunicum Vaccine Phase II Targovax Vaccine-based & Virus-based Phase I/II Bioinvent Antibody-based Phase I/II LTX-315 represents a novel approach, making “cold” tumors “hot”
5 Cancer remains a major medical need Sales of cancer drugs 2015-2022 Largest therapeutic area with 11% of total drug sales Cancer incidence is expected to grow – Every year, 14 million people are diagnosed with 200 cancer 180 160 Main pillars of therapy 140 – Surgery, radiation, chemo, hormonal and targeted 120 Large clinical need for better treatments 100 – 8.2 million deaths annually 80 60 40 20 0 2015 2022
6 Complex diseases require dynamic treatments Cancer immuno-therapy The role of the immune system is to defend the body against threats e.g. bacteria, cancer The immune system works in a variety of ways Cancers hide and constantly transform to trick the immune system resulting in a constant “power struggle” between the immune system and the cancer Immune oncology helps the immune system to fight cancer by boosting or breaking different mechanisms A diverse response from the immune system is likely to be more successful to win over the disease
7 ICIs – the first wave in cancer immunotherapy With ICI’s, immune oncology has taken center stage in the pharmaceutical industry becoming an attractive oncology segment Yervoy (BMS) Tecentriq Keytruda (MSD) (Roche/Genente ch 2011 2012 2013 2014 2015 2016 2017 2018 2019 Durvalumab (AstraZeneca) Avelumab (Merck / Pfizer) Opdivo (BMS)
8 ICIs – a paradigm shift in cancer treatment Next wave is to develop combinations ICI’s : significant progress but no silver bullit Checkpoint Inhibitors have revolutionised cancer treatment • The success of immunotherapies has changed the way cancers today representing the new backbone of cancer treatment are being treated • Combinations of immunotherapies have shown significant higher response rate than monotherapy Anti-CTLA4 and anti-PD1 clinical data in adv. melanoma Non- Grade 3/4 AE’s Proportion alive ICIs Responders responders (side effects) Immune therapy combination Yervoy 20% 80% 20-30% Long term survival Opdivo 40% 60% 10-20% Immune therapy monotherapy Keytruda 33% 67% 10% Long term survival Combination Chemotherapy / radiation therapy Untreated of Yervoy and 58% 42% 55% Opdivo Time from treatment Source: EvaluatePharma (2016)
9 ICI’s allow T -cells to attack cancer by removing the brakes ICI’s Tumor specific = Increase the activity of T-cells T-cell activation Removing the brakes
10 ICIs: Data indicates efficacy only in ”hot” tumors Few effector T cells ASCO/ESMO data confirms most tumours are ” cold ”, non -T-cell inflamed, lacking effector cells (CD8+) ICIss require a T-cell inflamed tumor microenvironment for efficacy (”hot” tumor) Major unmet clinical need – optimising immunotherapy Many effector T cells – Increase efficacy by inducing T-cell inflamed tumor microenvironment (hot tumors) – Checkpoint inhibitor therapy allows immune responses to eliminate cancer cells (Fig modified from Sharma, and James P. Allison, Science 2015 )
11 LTX-315 enabling checkpoint inhibitors ” cold ” tumours to ”hot” ICIs does not work in cold tumors LTX-315 will make cold tumors hot and enhance the proportion of cancer patients responding to ICIs Padmanee Sharma, and James P. Allison, Science 2015;348:56-61
LTX-315 unique MoA – making cold tumors hot LTX-315 releases potent immune stimulants and a broad repertoire of tumor antigens Zhou, Cell Death & Disease 2016. Zhou, Oncotarget 2015.

LTX-315 expands T-cell clonality in treated tumors Enhances immune responses to tumor antigens The diversity of T-cell clones is significantly enhanced in LTX- 315 treated tumors versus untreated tumors Each T-cell clone recognizes different tumor antigenes LTX-315 induces release of neo-antigenes that some of the T-cell clones generated recognize Cancer model: Murine B16 melanoma. Adaptive Biotech’s TCR sequencing platform ( immunoSEQ)
LTX-315 and tumor heterogenity Tumor heterogenity limits the efficacy of therapies By injecting LTX-315 in multiple lesions a broader and more representative tumor antigen repertoire is presented for T-cells Fig from Jamal-Hanjani, Clin.Cancer Res, 2015
