Clinical Progress in the Development of Immunotherapy for Advanced Cancer: Focus on Targeted Therapy Combinations

JasonLukeJason J. Luke, M.D., FACP, Assistant Professor, Medicine, Hematology/Oncology, University of Chicago

Immunotherapy is a centerpiece of melanoma treatment and early results in lung, kidney and bladder cancers suggest robust activity. Prior to immune-checkpoint blocking antibodies, standard of care in most tumors included targeted and chemotherapies. A clear imperative is to understand which treatments are rational partners for immunotherapy and which may be combined safely. Immunotherapy combinations completed and in development in multiple tumors will be discussed.

2:15 Identification and Optimization of T Cell-redirecting Asymmetric Bispecific Fully IgG Antibody

TakahiroIshiguroTakahiro Ishiguro, Ph.D., Researcher, Discovery Research, Chugai Pharmaceutical Co., Ltd.

T cell engaging bispecific antibody currently tested in clinical trial is BiTE molecules which are different from most popular IgG antibodies. We have generated T cell engaging antibody which is asymmetric bispecific fully IgG antibody recognizing CD3 and tumor specific antigen. Validated proprietary antibody engineering technologies were applied to enable large scale manufacturing of the bispecific antibody. Identification, optimization and pharmacology of this bispecific antibody will be presented.

2:45 Re-Envisioning “Classical” Cancer Therapy through the Lens of the Immune System to Develop Optimal Combination Immune Therapies

Israel-LowyIsrael Lowy, M.D., Ph.D., Vice-President, Clinical Sciences; Head, Translational Science and of Oncology, Regeneron Pharmaceuticals, Inc.

Regeneron is conducting new clinical trials with REGN1979, an anti-CD20xCD3 bispecific antibody, to treat CD20+ NHL or CLL, and REGN2810, an anti-PD-1 mAb for multiple tumor types. Each is being developed as an immunologic foundation for therapeutic regimens capable of eliciting durable responses. Further augmentation of anti-tumor activity by combination with classical agents will not rely on standard of care dosing, but instead seek to optimize their immune enhancing effects.

3:15 IMCgp100 ImmTAC: A Bispecific TCR Anti-CD3 Fusion for the Treatment of Malignant Melanoma
Annelise-VuidepotAnnelise Vuidepot, Ph.D., Head, Protein Science, Immunocore Ltd.ImmTACs are soluble bispecific-TCR-antiCD3 fusions suitable for the treatment of several tumor types.

8:30 Chairperson’s Remarks

Steven Coats, Ph.D., Senior Director, R&D, MedImmune

8:35 Multifunctional ADCs Unleash the Limitations of Conventional ADCs

Zhenwei (David) Miao, Ph.D., CTO, Sorrento Therapeutics

Our multifunctional ADC platform is able to expand the scope of the conventional ADC format that is limited by one target and one class of payloads. In this presentation, we will talk about the design and conjugation process of multifunctional ADCs from the regular IgG antibodies. The newest in vitro and in vivo results of multifunctional ADCs with improved potency and safety profiles will be discussed as well in the case studies.

9:05 Bi-Specific Redirected T Cell Killing Using Site Specific Incorporation of Tumor Cell Ligands

Marco-GymnopoulosMarco Gymnopoulos, Ph.D., Group Leader and Project Leader, Ambrx, Inc.

Our novel bi-specific conjugate (anti CD3-Folate) utilizes Ambrx’s RECODE™ technology that site-specifically incorporates novel amino acids into proteins recombinantly expressed in E.coli. Folate is chemically linked to the anti CD3 Fab containing the unnatural amino acid. Ambrx’s bi-specific conjugate is developed for targeting epithelial ovarian cancer and consists of a Folate entity that binds to FOLR1 receptor on tumor cells and anti-human CD3ε Fab that binds to the CD3 receptor on T cells. The concurrent engagement of T cells and ovarian cancer cells by anti CD3-Folate leads to T-cell activation and subsequent target cell lysis.

9:35 Dual-Targeting Triplebodies for the Elimination of Leukemic Blasts and Leukemia Stem Cells

GeorgFeyGeorg H. Fey, Ph.D., Professor Emeritus, Biology, University of Erlangen-Nuremberg

Triplebodies carry 3 single-chain Fv (scFv) binding domains in a single polypetide chain. The 2 distal modules bind 2 different targets on the same cancer cell, the central one a trigger on a cytolytic effector (NK- or T-) cell. Triplebody 33-16-123 binds CD33 and CD123 on acute mye¬loid leukemia (AML) cells, and recruits NK cells through CD16 (Fc gamma RIII). This pair allows us to target both AML blasts and AML Leukemia Stem Cells (LSCs), the presumed culprits responsible for Minimal Residual Disease (MRD) and frequently life-limiting relapses.

11:05 Harnessing Effector and Regulatory Pathways for Immunotherapy with DARTs

Scott Koenig, M.D., Ph.D., President & CEO & Director, Macrogenics, Inc.

Monoclonal antibodies (mAbs) are a mainstay of therapy for treating or preventing malignancies, autoimmune disorders, and infectious diseases. Engineering modifications in the primary structure of certain domains of mAbs or combining them with small molecules or toxins has enhanced their therapeutic potency in some cases and has led to recent regulatory approvals of the next-generation of biologicals. In this presentation, promising approaches to modulate physiological mechanisms with Dual Affinity Re-Targeting molecules or DARTs will be discussed with illustrations of their utility to treat leukemias and solid tumors, autoimmune diseases, or viral infections with our clinical and preclinical candidates.

11:35 Development of a Novel HER2-Targeting ADC to Address Unmet Medical Needs

John Li, Ph.D., Senior Scientist, Biosuperiors, MedImmune

Only 20-25% of the breast cancer patients are eligible for currently approved anti-HER2 therapies. Not all eligible patients respond to the therapies; moreover the vast majority of patients who initially respond to the treatment will eventually relapse. To date metastatic breast cancer remains an incurable disease. This presentation will discuss the development of a novel HER2-specific biparatopic antibody-drug conjugate and its potential in treating metastatic breast cancer patients that are refractory to or ineligible for current HER2-targeted therapies.
