Seminars

Thursday 25th June 2026
Panel Discussion: Utilizing Discovery Platforms to Hunt for the Perfect Target & Advance T-Cell Engager Efficacy in Solid & Liquid Tumors
4:30 pm
  • Discussing the methodologies currently used to identify antigens in multiple myeloma and B-cell lymphoma
  • Debating whether therapeutic failure in hematologic cancers stems from T-cell exhaustion or from a lack of high-density, specific antigens to target
  • Identifying shared antigens vs personalized neoantigens in solid tumor populations
Thursday 25th June 2026
Building Multi‑Specific T‑Cell Engagers for Heterogeneous, Hard‑to‑Treat Tumors
2:30 pm
  • A purpose‑built approach addresses the limiting challenges of narrow therapeutic windows and target heterogeneity by extending T‑cell engager success to pMHC targets.
  • Trackers, small soluble TCR‑derived binding elements, leverage the natural pMHC–TCR interaction to drive precise tumor cell killing while maintaining antibody‑like developability.
  • The Broadcast platform identifies optimal target pairs, discovers and optimizes novel Trackers with drug‑like properties, and designs multi‑specific formats that expand tumor coverage and increase the number of patients with potential to benefit
