Presentation Details
Title: Neo-STAT: A new biologics platform for selective targeting of tumor-specific T cells with enhanced antigen modularity
Presenter: Ahmet S. Vakkasoglu, Ph.D., senior scientist
Date: August 31-September 4, 2020
The poster highlights the engineering of the Neo-STAT platform, a scaffold with pocket-stabilized, peptide-free HLA molecules that enables enhanced antigen modularity through exogenous peptide loading. Compared to first generation scaffolds, the design of Neo-STAT improves the productivity and efficiency of scaffold production. Additionally, Neo-STAT biologics can incorporate diverse T cell epitopes, including peptides bearing post-translational modifications, peptide mixtures and peptides derived from tumor neo-antigens, thereby broadening the flexibility and therapeutic impact of the Immuno-STAT platform to target a wider spectrum of disease-associated epitopes.
"We are pleased to be presenting the Neo-STAT platform, which was developed to allow for the generation of therapeutic molecules incorporating diverse T cell epitopes," said Anish Suri, Ph.D., president and chief scientific officer of Cue Biopharma. "The Neo-STAT platform enables us to access a wider range of therapeutically relevant epitopes, including near-term applications in cancer immunotherapy with shared as well as personalized tumor antigens. In addition to cancer immunotherapy, we are also assessing the potential applications of Neo-STAT in infectious diseases, particularly against novel pathogens where immediate T cell responses could provide protective immunity before other prophylactic vaccination approaches are developed."
About Immuno-STAT
Immuno-STAT biologics are designed for targeted modulation of disease-associated T cells in the areas of immuno-oncology and autoimmune disease. Each of our biologic drugs is designed using our proprietary scaffold comprising: 1) a peptide-MHC complex (pMHC) to provide selectivity through interaction with the T cell receptor (TCR), and 2) a unique co-stimulatory signaling molecule to modulate the activity of the target T cells.
The simultaneous engagement of co-regulatory molecules and pMHC binding mimics the signals delivered by antigen presenting cells (APCs) to T cells during a natural immune response. This design enables Immuno-STAT biologics to engage with the T cell population of interest, resulting in highly targeted T cell modulation. Because our drugs are delivered directly in the patient’s body (in vivo), they are fundamentally different from other T cell therapeutic approaches that require the patients’ T cells to be extracted, modified outside the body (ex vivo), and reinfused.
