SC3: Oligonucleotides for Cancer Immunotherapy



Oligonucleotide-based therapies are now gaining attention as an alternative to antibody and small molecule-based therapies for cancer immunotherapy. In cancers, where current treatment options are limited by efficacy and specificity, oligonucleotide-based drug modalities are offering a good alternative. This course will bring together experts who will share their perspectives on the opportunities and challenges underlying the generation of novel, more targeted and effective oligonucleotide-based drugs for cancer immunotherapy.


6:30 Welcome Remarks and Speaker Introductions

6:45 RNAi Therapy to Potentiate Cancer Immunotherapy

Shanthi Ganesh, PhD, Associate Director, Preclinical Oncology, Dicerna Pharmaceuticals, Inc.

  • Steps for effective immunotherapies
    • Understanding the strategies cancer utilizes to evade from immune system (oncogenic pathways and others)
    • Priming non-inflamed tumors to increase T-cell infiltration (β-catenin inhibitors, , STING agonists, TLR agonists, Oncolytic viruses etc.)
    • Tuning suppressive tumor microenvironment (MDSCs,Tregs, CAFs etc.)
    • Evaluating and removing co-inhibitory signals/ checkpoints (PD-1, PD-L1, CTLA-4 ab)
  • Unique role of RNAi therapeutics in priming tumors and shaping TME (β-catenin/KRAS RNAi triggers)
  • Importance of careful selection of combination partners for an effective personized medicine
  • Examples of pre-clinical evaluations and discussion of how that can be translated into clinical settings

7:30 Coffee and Dessert Break

7:45 TLR9 Agonist Spherical Nucleic Acids (SNA): Targeting the Tumor Microenvironment and Systemic Immune Activation for the Treatment of Immunogenic Cancers

Weston Daniel, PhD, Senior Director Program Management, Exicure, Inc.

  • Spherical nucleic acids (SNA) for improved cellular delivery
  • Oligonucleotides targeting TLR9 for innate immune response activation
  • Significance of innate immune activation for immuno-oncology applications
  • AST-008 — a novel SNA for immuno-oncology applications
  • AST-008 preclinical and early clinical results

8:30 MAEGI as a New Class of Cancer Immune Gene Therapy

Ganesh_ShanthiShanthi Ganesh, PhD, Associate Director, Preclinical Oncology, Dicerna Pharmaceuticals, Inc.

As an Associate Director, Shanthi Ganesh leads the Oncology platform at Dicerna Pharmaceuticals, where she develops novel RNAi drugs and evaluates them in combination with targeted therapies and checkpoint inhibitors. Before joining Dicerna, as a Research Investigator at Novartis, she focused on utilizing RNAi therapeutics for multiple oncology targets, where she also led a targeted delivery platform to establish delivery of siRNA to tumor metastasis to demonstrate therapeutic efficacy. Prior to joining Novartis, she worked at two major Gene Therapy companies where she designed, developed and evaluated oncolytic viruses for treatment of cancer. Her work also contributed to the discovery of a systemically deliverable novel oncolytic virus and a new biotech company. She published extensively in siRNA and cancer therapeutics area. She also holds several patents and awards for her work in siRNA and oncology area. She has also been a member of ASCO and AACR for the last several years and attended and presented her work at several international conferences.
