Illuminating Shared Neoantigen Therapies to Induce More Durable & Robust Immunity in a Larger Patient Population

12:00 pm KRAS Mutation-Specific TCR-T Cells are Empowered for Improved Multi-Functionality & Durability by Inclusion of a Costimulatory Switch Protein

Synopsis

  • Generation of 3S TCRs from naïve repertoires of healthy donors that recognize KRASspecific mutations (mKRAS) display high specificity, high sensitivity and an excellent safety profile in recognition of mKRAS-expressing tumour cells
  • Co-expression of a PD1-41BB Costimulatory Switch Protein (CSP) armors TCR-T cells against PD-L1-mediated inhibition and enhances multiple cellular functions through intracellular activation of the 41BB costimulatory pathway, enabling TCR-T cells to function better in a hostile tumour microenvironment
  • Our automated method of producing enriched CD8+ TCR-T cells yields Drug Products with enhanced capacity to proliferate and persist upon repeated encounter with PD-L1- expressing tumour cells, supporting important parameters associated with durability

12:30 pm Neoepitopes Cancer Vaccine Monotherapy Positive Efficacy Randomized Phase 3 results in Non-Small Cell Lung Cancer with Resistance to Immunotherapy

Synopsis

  • Tedopi is a tumour-specific activating immunotherapy based on highly-selected and optimized tumour neoepitopes
  • Positive clinical efficacy of Tedopi versus chemotherapy in a randomized Phase III trial in Non-Small Cell Lung Cancer in patients with secondary resistance after failure of checkpoint inhibitors: Significantly better survival: 44% overall survival at 1-year, versus 27% with chemotherapy; Significantly better safety profile: 3-fold less severe Grade 3-5 adverse events and significantly better quality of life.

1:00 pm Targeting Neoantigens with Invariant Natural Killer T Cells

Synopsis

  • MiNK therapeutics is developing iNKT-based allogeneic cell therapy products for cancer. Invariant Natural Killer T cells (iNKT) recognize glycolipids presented on CD1d through their invariant TCR.
  • iNKT cells can be engineered to stably express a 2nd TCR, and both TCRs are fully functional
  • We are developing a portfolio of phospho-peptide neoantigen-specific TCRs for iNKT-based applications

1:30 pm Lunch & Networking

3:30 pm Afternoon Networking Break

4:00 pm Delving into the Mechanism of Action of Neoantigen Antibodies to Aid the Development of Highly Effective Combination Strategy Towards More Successful Therapies

Synopsis

  • What is the mechanism of action of a neoantigen antibody being used in combination?
  • How to effectively use the neoantigen antibody, should it be applied before the checkpoint inhibitor or after?
  • Would it be beneficial to combine with more than one other approach?

4:30 pm Multitargeted Self-Replicating RNA for Off-The-Shelf Cancer Precision Immunotherapeutics

Synopsis

  • Replicate Bioscience’s self-replicating RNA platform supports a unique and powerful approach to preventing and reversing the emergence of common acquired resistance mutations
  • Using multigenic self-replicating RNA we have created precision immunotherapeutics that can be dosed in combination with SOC approved cancer agents, thus maintaining selective pressure on the tumour
  • Mechanistically, the combination of the Replicate immunotherapy and the SOC creates a lose-lose situation wherein wild-type tumour clones are controlled by the SOC treatment and resistance mutant positive clones die by the precision immunotherapeutic. We term this synthetic immune lethality
