Bernard A. Fox, PhD, Chief, Laboratory of Molecular and Tumor Immunology, Providence Health & Services; CEO, UbiVac
3:10 Probody Therapeutics in the Treatment of Cancer
Marcia Belvin, PhD, Vice President, Oncology Research, CytomX Therapeutics
Probody™ therapeutics are fully recombinant antibody-based prodrugs designed to remain largely inactive in circulation until proteolytically activated in the tumor microenvironment (TME). They are designed to protect normal tissues while increasing
the concentration of active antibody in tumors, thus widening the therapeutic index. Probody technology can be applied to multiple antibody-based therapies. Examples will be presented, including probodies based on checkpoint inhibitor antibodies targeting
PD-L1 and CTLA-4, antibody-drug conjugates, and T cell-engaging bispecifics.
3:40 Unraveling the Mechanisms of Action of Bispecific T Cell Engager (BiTE) Molecules in Immuno-Competent Mice Expressing a Chimeric Human/Mouse CD3ε Receptor
Olivier Nolan Stevaux, PhD, Principal Scientist, Oncology Research, Amgen
The development and success of Blincyto®, a Bispecific T Cell Engager (BiTE®), to treat acute lymphoblastic leukemia has expanded the class of immunotherapy agents used to treat cancer. BiTE antibody constructs consist of a single-chain Fc antibody
containing tandem single-chain variable fragments (scFv) recognizing the CD3 receptor on T lymphocytes and a tumor-associated antigen and induce redirected T cell cytotoxicity and tumor cell lysis.

Steve Doberstein, PhD, CSO & Senior Vice President, Research, Nektar Therapeutics
10:25 ADU-S100, a First-in-Class STING Agonist, Induces Anti-Tumor Immunity and Enhances Checkpoint Inhibition
Sarah McWhirter, PhD, Executive Director, Pharmacology/Research, Aduro Biotech, Inc.
T cell checkpoint inhibitors set a clinical paradigm providing significant benefit to patients diagnosed with advanced cancer. Despite success, the majority of patients do not respond to PD-1, PD-L1 or CTLA-4 blockade. Raising the number of patients benefiting
from cancer immunotherapy requires novel therapeutic approaches aimed at these non-responders, for instance by modulating the STING pathway using the first-in-class clinical STING agonist ADU-S100.
10:40 Targeting the CD47 “Do Not Eat” Signal with SIRPaFc Decoy Receptors
Bob Uger, PhD, CSO, Trillium Therapeutics,
Inc.
CD47 is an innate immune checkpoint that binds to SIRPα and delivers a “do not eat” signal to suppress macrophage phagocytosis. Many tumors express high levels of CD47 to escape macrophage-mediated immune surveillance. Trillium Therapeutics
is developing SIRPaFc fusion proteins to block the CD47 “do not eat” signal. The emerging clinical data for this novel class of innate immune system checkpoint inhibitors will be discussed.
10:55 ATOR-1017, a Tumor-Directed Fcγ-Receptor Cross-Linking Dependent 4-1BB Agonistic Antibody
Christina Furebring, PhD, Senior Vice President, R&D, Alligator Bioscience
ATOR-1017 is a FcγR crosslinking dependent 4-1BB agonistic antibody with an activation profile that minimizes the risk for inducing systemic immune activation and toxicity. ATOR-1017 was designed for an optimal efficacy and improved safety by combining
the IgG4-format that mediates a potent FcγR cross-linking with a unique binding epitope on 4-1BB. The immune activation will be directed to tumors co-expressing both specific FcγRs and 4-1BB. ATOR-1017 is currently in preclinical development
phase, and clinical studies are planned for 2019.
11:10 Advanced Cytokine Engineering for Immunotherapy
Steve Doberstein, PhD, CSO & Senior Vice President, Research, Nektar Therapeutics
Many native cytokines that activate important immunological pathways are difficult to use therapeutically due to toxicity, poor pharmacokinetics, and sub-optimal pharmacodynamics. We have engineered new medicines using polymer conjugation to improve potency
and tolerability by optimizing PK/PD and receptor activation. NKTR-214, for example, is a novel agonist of the IL2 receptor pathway that maximizes CD8 T cell tumor infiltration over Treg proliferation. We will discuss additional examples of molecules
optimized to elicit desirable immunological outcomes.
11:25 Hexavalent Agonists Targeting the TNFR Superfamily for Cancer Immunotherapy
Oliver Hill, PhD, Vice
President, Molecular Biology, Apogenix
Apogenix novel hexavalent TNFR-SF agonists (HERA) are developed for the immunologic treatment of cancer. They are based on trivalent but single-chain molecular mimics of the TNF-SF receptor binding domains fused to a dimerization scaffold. The resulting
hexavalent fusion proteins are potent TNFR-SF agonists that activate distinct immune cell populations. HERA compounds show single agent anti-tumor activity and provide exciting opportunities for combinatorial treatment. The presentation will focus
on data obtained with HERA-CD40L, HERA-CD27L and HERA-GITRL.
11:40 Extended Q&A with Session Speakers
11:55 Make Your I/O Clinical Trials Successful Using iCore - A Cloud Based AL ML Enabled Informatics Platform
Mohan Uttarwar, CEO, iNDx Technology
iCore is a cloud based AI ML enabled innovative informatics platform for managing I/O clinical trials and biomarker driven studies successfully. iCore - organizes, aggregates, analyzes, visualizes multi-dimensional data sets and can interrogate between
different data sets using NLP Technology
12:25 pm Enjoy Lunch on Your Own
1:35 Refreshment Break in the Exhibit Hall with Poster Viewing
2:05 Chairperson’s Remarks
Michael Koratich, MS, Associate Director, Head, Oncology, Drug Development, Southern Research
2:10 Multiple Avenues to T Cell Activation with Bispecific Antibodies
John Desjarlais,
PhD, Senior Vice President, Research, CSO, Xencor
Xencor has applied its XmAb bispecific technology platform to create multiple novel modalities for T cell derepression and activation. These include dual checkpoint inhibitors such as a PD1 x CTLA4 bispecific antibody, and a CTLA4 x LAG3 bispecific antibody
that combines productively with anti-PD1 for triple checkpoint blockade. We have also discovered a highly active PD1 x ICOS bispecific antibody that productively combines checkpoint blockade and costimulation into a single molecule. Finally, we have
utilized our heterodimeric Fc domain to create a novel long-acting IL15/IL15Ra-Fc format for immunotherapy.
2:25 Leveraging Bispecific Molecules for Combination Immunotherapy of Cancer
Jon Wigginton, MD, Senior Vice President, Clinical Development & CMO, MacroGenics
2:40 Presentation to be Announced
2:55 ProTIA – Bispecific T Cell Engagers Designed for Activation by Tumor-Associated Proteases
Volker Schellenberger, PhD, President and CEO, Amunix
Amunix developed a novel format of bispecific T cell engagers called ProTIA (Protease Triggered Immune Activators). ProTIAs combine three tumor-targeting modalities: 1) tumor antigen binding; 2) localized activation by tumor-associated proteases; 3) limited
exposure of healthy tissues due to polymer-based prodrug format (EPR effect). ProTIAs are administered as long-acting prodrugs. Protease activation releases a highly potent (1000x increase) BiTE-like molecule at the tumor site. Activated ProTIAs have
a very short circulatory half-life resulting in rapid removal of non-specifically activated molecules. Tumor-specific antibodies can be readily converted into ProTIAs resulting in a large widening of the therapeutic index. The rate and protease selectivity
can be readily adjusted.
3:10 Unbiased Functional Screening of Large Bispecific Antibody Panels to Unlock Novel Biology
Mark Throsby, PhD,
Executive Vice President & CSO, Merus NV
The bispecific antibody format represents an emerging therapeutic modality. We have developed a set of robust and validated technologies that permits unbiased in-format functional screening to identify human full-length IgG bispecific antibodies candidates
with superior therapeutic properties. Two case studies will be presented where this approach has been successfully employed to discover lead candidates with differentiating properties that are now in clinical development.
3:25 Modulating Anti-Tumor Immune Responses with B-Body Bispecific Antibodies
Bonnie Hammer, PhD,
Vice President, Biologic Development, Invenra
Bispecific antibodies have distinct advantages over monospecific antibodies including more selective targeting of specific cell populations and enabling novel mechanisms of action. We have used our B-Body™ platform to create bispecific/multispecific
antibodies for redirected T cell killing, for enhanced agonist activity, and for specifically targeting subsets of cells for elimination. We demonstrate the advantage of screening for functional activity, rather than just binding, to identify the
desired drug candidate.
3:40 Extended Q&A with Session Speakers
3:55 Characterization of a Human PD-1/PD-L1 Transgenic Mouse Model for Evaluation of Single and Combination Agent Therapy
Michael Koratich, MS, Associate Director, Head, Oncology, Drug Development Division, Southern Research
Evaluating checkpoint therapeutics for use as combination agents is a significant focus of the oncology community. Here we explore the suitability of a PD-1 and PD-L1 transgenic mouse system to serve as a model for checkpoint and chemotherapy combination
evaluation.

10:50 Chairperson’s Remarks
Jing Qing, PhD, Principal Scientist, Global Research Lead for T-VEC, Amgen
11:00 Applications of Poxviral Vectors in Immuno-Oncology
Christopher R. Heery, MD, CMO, Bavarian Nordic
Dr. Heery will discuss the use of poxviral vectors to address multiple issues in immuno-oncology: 1) the specific activation of T cells against tumor antigens; 2) activation of innate immune responses, including systemic cytokine profile modification
and NK activation; 3) modification of tumor microenvironment through TLR9 and cGAS/STING pathways.
11:15 OncoVEXmGM-CSF Induces Durable and Systemic Anti-Tumor T-Cell Immunity
Jing Qing, PhD, Principal Scientist, Global Research Lead for T-VEC, Amgen
Talimogene laherparepvec (T-VEC) is a first-in-class oncolytic immunotherapy derived from herpes simplex virus type 1 (HSV-1). To gain insights into T-VEC-induced systemic anti-tumor immunity, we utilized multiple murine syngeneic tumor models to investigate
the immune responses triggered by OncoVEXmGM-CSF, a virus modified similarly to T-VEC except that it contains mGM-CSF instead of hGM-CSF. We have demonstrated that OncoVEXmGM-CSF is able to induce durable, T cell-mediated immunity against syngeneic
tumors. Recent data from clinical studies of T-VEC in combination with checkpoint blockade will be discussed too.
11:30 Toca 511 and Toca FC: A Drug Combination Based on a Conditionally Lytic Retrovirus with a Different Immunotherapy Target Profile
Douglas Jolly, PhD, Executive Vice President, R&D, Tocagen, Inc.
Toca 511 (vocimagene amiretrorepvec) is a retroviral replicating vector that selectively spreads in tumors and leads to local high concentrations of fluorouracil (5-FU). This generates anti-tumor immune responses and durable complete responses in a Phase
I recurrent High-Grade Glioma trial. A consequent 380 patient Phase III trial completed enrollment September 2018. Immunological assay data from HGG and solid tumor trials supports a non-typical immuno-oncology profile in responders and after treatment.
11:45 Voyager-V1: Systemic, Single-Cycle, Trackable Oncolytic Virotherapy
Stephen J. Russell, MD, PhD, CEO, Vyriad, Inc.
Voyager-V1 is a recombinant oncolytic vesicular stomatitis virus engineered to encode both interferon beta (for immune enhancement and serum monitoring of virus pharmacokinetics) and the thyroidal sodium iodide symporter (for radionuclide enhancement
of tumor cell killing and for imaging the spread of the virus infection). Oncolytic viruses have maximum cancer-destructive capacity when the recipient has no pre-existing antiviral immunity. Also, systemic delivery or systemic spread from an
injected tumor site are greatly hindered by preformed antiviral antibodies. Single cycle therapy is therefore highly rational with the added advantage of convenience for the patient and treating physician. Pharmacokinetic data from the monitoring
of reporter gene expression guides the clinical development process. Voyager-V1 is being evaluated in multiple ongoing Phase I clinical trials, and the accumulating pharmacokinetic data are proving to be quite enlightening. Insights gained from
these ongoing studies will be discussed.
12:00 pm Novel microRNA Attenuated Oncolytic Virus with Combinatorial Immune Payloads for the Treatment of Metastatic Cancer
Brian Haines, PhD,
Senior Director, Pharmacology & Toxicology, Oncorus
In this presentation, Oncorus’ proprietary OV platforms will be presented. miR attenuation allows conditional and selective replication in tumor cells while sparing normal cells, thereby reducing toxicity. In addition, virus alterations allow
the incorporation of multiple payloads within one virus in order to augment immune activation and systemic anti-tumor activity. The ultimate goal is to generate safe yet powerfully efficacious OV therapeutics for the treatment of cancer.

1:50 Chairperson’s Remarks
Yisrael Katz, MD, Director of Clinical Applications, Calviri, Inc.; Center for Innovations in Medicine, Arizona Biodesign Institute
2:00 Artificial Intelligence to the Rescue: Towards Personalized, Neoantigen-Targeted Immunotherapeutics
Raphaël
F. Rousseau, MD, PhD, Executive Vice President, Head of Development and CMO, Gritstone Oncology
Genetic instability is a hallmark of cancer. Consequently, each patient’s tumor genome is different from their normal cells. This DNA difference can generate rare, highly tumor-specific, new protein antigens. Deep-learning models trained on
large-scale data generated from human tumors allow for superior identification of these neoantigens. Delivering these neoantigens to patients in a highly immunogenic context should drive their immune system to attack and destroy their own tumor.
2:15 Overcoming Epigenetic Immune Ignorance through in situ Vaccination
Robert Pierce,
MD, Scientific Director, Immunopathology Core, Fred Hutchinson Cancer Research Center
Pre-existing anti-tumor T cell responses appear to be a prerequisite for response to anti-PD1/PDL1 monoclonal antibody (mAb) therapeutics. In contradistinction, patients with a paucity of tumor-infiltrating lymphocytes (TILs), including the ‘immune
ignored’ phenotype, are unlikely to respond to these therapies. Epigenetic suppression of antigen presentation and processing machinery (APM) may represent a common mechanism of this ‘immune ignored’ phenotype.
In situ vaccination and/or other intralesional therapies that result in local expression of interferon-gamma can result in reversal of this epigenetic suppression, leading to enhanced responsiveness to anti-PD1
blockade.
2:30 The Discovery and Development of Novel Monoclonal Antibody, NEO-201 Targeting a Novel Neoantigen
Philip Arlen, MD, President & CEO, Precision Biologics
NEO-201 was developed from an allogeneic colorectal cancer vaccine that had previously shown activity in patients with metastatic colorectal cancer. This vaccine was derived from an immunogenic component of the cell membrane from pooled surgical specimens
from both primary and metastatic colon cancer. Patients who benefited from the vaccine in the prior clinical trial produced and sustained high levels of serum IgG against the vaccine. Several thousand candidate antibodies were screened against
this vaccine, and NEO-201 was a lead candidate that demonstrated the ability to bind to colon cancer as well as other carcinomas vs. normal tissue. In addition, it has antibody-dependent cellular cytotoxicity (ADCC) as a mechanism of tumor kill.
First-in-human studies are planned to be initiated in late 2018.
2:45 Generating Potent CD8-Dominated Neoantigen-Specific T Cell Responses with Novel DNA Vaccine
Agnete Fredriksen, PhD, CSO, Vaccibody
Vaccibody has a unique platform technology able to potentiate vaccines by attracting, activating and delivering antigens to antigen presenting cells. Recent clinical data indicate an important role of neoantigen-specific T cells in patients that benefit
from immunotherapies. A Vaccibody DNA vaccine opens up for a rapid and cost-effective manufacturing perfect to develop commercially viable patient-specific vaccines on demand. A clinical study using Vaccibody neoantigen vaccines in advanced cancer
is ongoing.
3:00 A Revolutionary Technology to Develop Cancer Type-Specific Vaccines for Any Cancer
Yisrael Katz, MD,
Director of Clinical Applications, Calviri, Inc.; Center for Innovations in Medicine, Arizona Biodesign Institute
Frameshift peptides have become recognized as a neoantigen source separate from DNA mutations. We have invented a serological assay, not requiring biopsy, that rapidly identifies reactivity to all potential frameshift neoantigens. This yields a huge
antigen pool with proven immunogenicity – bypassing the need for prediction algorithms. With thousands of reactive frameshift peptides per patient and 20-30% overlap across disease cohorts, we can develop pre-made cancer type-specific vaccines
for any cancer.

3:45 A New TCR-Mimic (TCRm) Technology Used in Solid and Hematologic Cancers
Bijan Nejadnik, MD, CMO, Eureka Therapeutics
ARTEMIS T-cell receptor platform was shown to be safe and effective in preclinical and clinical studies against CD19-positive NHL. ARTEMIS T-cells matched the cancer-killing potency of CAR-T therapies but with a dramatic reduction in the levels of
inflammatory cytokines released. A human TCRm using a fully human antibody added to the ARTEMIS effector domain was developed to target an AFP-peptide/HLA-A2 complex on HCC liver cancer cells. Once engaged onto this complex, the TCRm engineered
T-cell is activated to kill the cancer cell. TCRm against AFP-peptide was safe and effective in preclinical and POC clinical studies.
4:00 TCR-Based Therapies for Solid Tumors Using Novel Antigens
Steffen Walter, PhD, CSO, Immatics US
TCR-based therapies offer the largest possible space of potentially targetable antigens. We have used ultra-sensitive mass spectrometry to identify novel and safe targets for TCR-based therapies. Matching specific TCRs were routinely identified from
healthy donors and systematically validated for efficacy and safety. We have used these two discovery platforms, named XPRESIDENT® and XCEPTOR®, to propel novel TCR-based therapies in adoptive cell therapy and using bispecific T-cell engagers
(TCER®). This has culminated in four clinical-stage programs.
4:15 Controlling Efficacy and Safety of T Cell Immunotherapies Using Molecular Switches
Paul Woodard, PhD, Vice President and Head, Clinical Development, Bellicum Pharmaceuticals
Current adoptive cellular therapies (ACTs) have shown promising clinical responses in hematological malignancies; however, their durability in hematological malignancies appears limited and most ACTs have shown little to no clinical activity in solid
tumors due to lack of persistence and suppressive tumor microenvironments (TMEs). Bellicum is designing next-generation controllable ACTs that are designed to activate or eliminate therapeutic cells, as well as overcome the suppressive TME, thereby
providing potentially greater efficacy and safety.
