8:25 Chairperson’s Opening Remarks

8:30 Introduction to Immunology for Biotherapeutics and the Role of T Regulatory Cells

Ethan_ShevachEthan Shevach, M.D., Senior Investigator, Laboratory of Immunology, National Institute of Allergy and Infectious Diseases, NIH

The major role of the immune system is to provide protective responses to pathogenic microorganisms. The immune system consists of several distinct cell types and each type plays a unique role. Dysregulation of the immune system can result responses against self-antigens and in the development of autoimmune diseases. A specialized subset of T lymphocytes, termed T regulatory (Treg) cells, functions to suppress anti-self responses. Modulation of Treg function with drugs or biologics represents a major approach to the treatment of autoimmune disease.

9:30 Antigen Processing and Presentation: the Basis of T Cell Activation

David_MarguliesDavid H. Margulies, M.D., Ph.D., Chief, Molecular Biology, Laboratory of Immunology Lab, NIAID, National Institutes of Health

Antigen Presenting Cells process protein antigens into peptides for binding by either Major Histocompatibility Class I (MHC-I) or Class II (MHC-II) molecules which are then displayed at the cell surface as peptide/MHC complexes where they are recognized by T cell receptors leading to T cell activation. Cell biological, biochemical, and structural details of these processes as we now understand them will be discussed.

10:30 Coffee Break in the Exhibit Hall

11:00 Applying Bispecific Technology to Modulate the Immune Response for Therapeutic Intervention

Paul_MoorePaul Moore, Vice President, Immunology and Cell Biology, Macrogenics, Inc.

Bispecific antibody based molecules afford therapeutic opportunities not feasible with single-target antibodies or combinations. The most advanced clinical strategy in oncology exploits the ability of bispecific molecules to co-engage T-cells with tumor cells resulting in tumor cell lysis and T-cell expansion. Additional approaches to leverage immune cells through bispecific targeting are being explored in oncology, autoimmunity and infectious diseases. These approaches will be summarized in the context of molecule design and target selection.

12:00pm Immunology Safety Considerations for Biotherapeutics

Rakesh_DixitRakesh Dixit, Ph.D., Vice President, R&D, Global Head, Biologics Safety Assessment, MedImmune, Inc.

In this presentation, I shall examine the challenges of biotherapeutics impacting on the immune response, and the challenges investigators face managing, dose, scheduling, and satisfying the regulatory requirements. The checkpoint inhibitors used for immunotherapy have a natural role in controlling autoimmune diseases such as Type 1 Diabetes and Lupus. Immunotherapies in general, and technologies modifying T cell function and those involving cytokines present dangers of autoimmune disease, cardiovascular disorders, and additional challenges, especially when used in combination.

1:00 Lunch

2:30 Biopharmaceutical Product Immunogenicity: What Causes It and What are the Safety and Efficacy Consequences?

Bonnie_RupBonita (Bonnie) Rup, Ph.D., Biopharmaceutical Consultant, Bonnie Rup Consulting

Biopharmaceuticals represent a rapidly growing class of therapeutic product, contributing significantly to advancing treatment of serious diseases including chronic inflammatory and autoimmune diseases, genetic deficiencies, and cancer. Unfortunately, unwanted immunogenic responses against some of these products can occur, often reducing efficacy and sometimes causing safety consequences such as hypersensitivity, immune complex disease, and autoimmune syndromes. In this talk, factors that affect the degree to which the immune system responds and the degree to which the response affects the efficacy and safety of the biopharmaceutical in patients are discussed.

3:45 Refreshment Break in the Exhibit Hall

4:15 Vaccines: Understanding the Mode of Action, Progress to Date, and On-Going Challenges

Michael_LacyMichael Lacy, Ph.D., Lead Scientist, Non-Clinical Development, Emergent BioSolutions

Complex immune responses result from the complexity of whole pathogen vaccines. Vaccines can be simplified to 3 general components, each of which is supplied by whole pathogens in a convenient package. Despite complex immunity within the recipient, measurements are limited usually to net immunity assessments. Emerging safety issues may lead to purified and quantified vaccine components. Purified immune stimulants that mimic native stimulants may be effective. Formulations may preserve epitopes and control unwanted immunity. Selection of conserved epitopes may bypass rapid mutational rates of pathogens.

8:25 Chairperson’s Remarks

8:30 Immuno-Oncology Part One: Harnessing the Body’s Natural Immune Response to Fight Cancer

Jochem_GokemeijerJochem Gokemeijer, Ph.D., Associate Director, Molecular Discovery Technology, Bristol-Myers Squibb

Checkpoint inhibitor as cancer treatment have shown remarkable response rates in previously hard to treat cancers by redirecting the body’s own immune system to recognize and eliminate tumor cells.

Here we will discuss the current state of I-O agents in the clinic, challenges related to toxicities, biomarker approaches for patient stratification and future directions of the field.

9:30 Immuno-Oncology Part Two: Adoptive T Cell Therapy

Jos_MelenhorstJ. Joseph (Jos) Melenhorst, Ph.D., Director, Product Development & Correlative Sciences, Center for Cellular Immunotherapies, University of Pennsylvania

The early realization that cancer patients may exhibit tumor-resident or circulating T cells that respond to the tumor has led to a flood of basic and translational studies aimed at characterizing the antigens recognized by T cells and the T cell receptor (TCR) chains responsible for this tumor specificity. Via rapid developments in gene engineering such receptors have been utilized in pre-clinical and even clinical studies to target tumor cells. In some cases, the native antigen affinity was altered to boost tumor reactivity, which sometimes led to the desired effect, occasionally with deleterious consequences. Similar biotechnological developments, fueled by discoveries in basic immunology, have led to the introduction of man-made tumor-targeting receptors made up of B cell and T cell domains, currently known as chimeric antigen receptors or CARs. In my two-part talk I will discuss the evolving field of adoptive T cell therapy, and compare and contrast tumor targeting efforts with allogeneic, autologous minimally manipulated to the TCR and CAR-redirected T cells. Topics to discuss are safety, efficacy, toxicity; clinical trials in hematologic and solid tumors, and future directions to enhance immunogene therapy of cancer.
