Session Abstract – PMWC 2019 Silicon Valley

Session Synopsis: Cancer immunotherapy, and in particular PD-(L)1 blockade, have made a significant impact on the treatment of cancer patients in recent years. However, despite the remarkable clinical efficacy of these agents in a number of malignancies, it has become clear that they are not sufficiently active for many patients. Initial evidence, for example with combined inhibition of PD-1 and CTLA-4 in melanoma and non-small cell lung cancer (NSCLC), has highlighted the potential to further enhance the clinical benefits of monotherapies by combining agents with synergistic mechanisms of action. There are multiple potential rational combinations using an immunotherapy backbone, including existing treatments such as radiotherapy, chemotherapy or molecularly targeted agents, as well as other immunotherapies. Rational trial designs based on a clear understanding of tumor biology and drug pharmacology remain critical.

Session Chair Profile

M.D., Professor in Residence and Program Leader for the Experimental Therapeutics Program, UCSF
Biography

Dr. Munster is a physician scientist who received her medical degree from the University of Bern, Switzerland. She completed her medical training at Indiana University Medical Center and Memorial Sloan-Kettering Cancer Center, New York where she then served on faculty as a breast cancer specialist prior to moving to the University of California, San Francisco, where she is Professor in Residence and Program Leader for the Experimental Therapeutics Program, as well as the Co-Leader of the Center for BRCA Research at Helen Diller Family Comprehensive Cancer Center. Her laboratory develops novel targeted cancer treatment strategies. Dr. Munster’s basic research also involves studies on heritable factors of tumor development and treatment. Her clinical mission is to more rapidly translate novel scientific discovery to patient care with a goal to allow patients with incurable cancer real time and broader access to scientific advances. Dr. Munster has published in numerous scientific journals and textbooks, and recently authored Twisting Fate, about her experience as an oncologist and cancer patient.

Speaker Profile

M.D., Distinguished Med Research fellow, VP, ARMO BioSciences, Eli Lilly
Biography

Dr. Oft is a co-founder of ARMO BioSciences, a late stage immuno-oncology company (now Eli Lilly) and an expert in immuno-oncology with indepth experience in pre-clinical, translational and clinical research and development. He oversaw the development of ARMO’s pipeline including pegilodecakin, from early target discovery through clincal development and was the architect of multicohort phase 1 design for expedited Phase 1 to Phase 3 development. He was a co-founder and CEO of Targenics, which merged with ARMO BioSciences. Prior to this Dr. Oft led discovery and development of immuno-oncology research at DNAX Inc. (now Merck Research Labs), was on the faculty at UCSF Cancer Center and on the Onyx Sorafenib team. He received his MD from the University of Erlangen, Germany with postdoctoral training at the Institute for Molecular Pathology in Vienna, Austria. He is a lead author on publications in Nature, Science and Cancer cell, and authored numerous patents.

Talk

Immunotherapy with Pegilodecakin and Anti-PD-1 in NSCLC/RCC
Immunooncology therapies aim to induce activation and expansion of tumor reactive CD8+ T cells. Pegilodecakin induces clonal expansion and activation of tumor reactive T cells and objective tumor responses as monotherapy in patients. Pegilodecakin increases tumor responses and overall survival in combination with chemotherapy of anti-PD-1 (RCC and NSCLC).

Speaker Profile

M.D., Professor and Chairman, Radiation Oncology, NYP, Weill Cornell Medicine
Biography

Dr. Formenti is the Chair of Radiation Oncology at Weill Cornell Medicine and the Associate Director of the Cancer Center. Trained as a medical and radiation oncologist she devoted her career to translate novel preclinical information to the clinic. Key to her formation was a year spent in Malcolm Mitchell’s laboratory at USC, in cancer immunology, that inspired her focus on the immune system. Her lab’s original demonstration that the abscopal effect of radiotherapy is immune-mediated has introduced effects of radiation, a paradigm shift in radiation and cancer biology. In this novel application, radiotherapy contributes at recovering an immunological equilibrium in the setting of metastatic cancer, by converting an irradiated metastasis into an in situ, individualized vaccine in the presence of immune checkpoint blockade (anti-CTLA­4, anti-PDL-1). Once successfully immunized against the irradiated site, the host can develop an anti-tumor immune response capable to reject the other metastases. In some patients with metastatic disease the combination of radiation and immune checkpoint blockade has resulted in complete remissions, sustained for years after treatment (without any other additional interventions). Dr. Formenti’s work has been funded by grants from NIH, DOD, ACS and Breast Cancer Research Foundation and is currently leading four investigator-initiated clinical trials of immunotherapy and radiotherapy.
