Afternoon Break & Refreshments
3:30 pm ACTM-838, a Novel Cell-Based Immunotherapy Enables Systemic Delivery with Tumor-Specific Effects & Generates Durable Anti-Tumor Immunity
Synopsis
- STACT (S. Typhimurium-Attenuated Cancer Therapy) is a novel immunotherapeutic modality that can be systemically delivered with tumor-specific effects
- Characteristics include: enriches in solid tumors, not healthy tissue, tumor-specific payload delivery and multiplexed targeting in a single therapy
- ACTM-838 is Actym’s lead development candidate, a STACT that encodes engineered IL15 + eSTING payloads. ACTM-838 has potent single agent activity against multiple tumor models after IV dosing with synergy when combined with PD-1. ACTM-838 induces profound myeloid and broad immune reprogramming of the TME leading to anti-tumor immunological memory
