Lead Program Toca 511 & Toca FC
Lead Program - Toca 511 & Toca FC Immune Activation Via the Tumor Microenvironment 5-FU also eliminates immunosuppressive myeloid cells (MDSCs and TAMs), activating antitumor immunity Gamma retrovirus Toca 511 selectively infects tumor, persists and spreads through tumor while delivering the CD gene 1 2 3 Toca FC prodrug locally converted to 5-FU chemotherapeutic within the tumor, killing cancer cells and resulting in activation of antigen presenting cells and T cell priming
Toca 511 & 5-FC Activates a Durable Anti-Cancer Immune Response Locally, within tumor microenvironment, Toca 511 & Toca FC alter immune profile Increased T cell immune infiltrates in tumor (COLD → HOT) Immune effects are CD4 & CD8 T cell-dependent and correlate with immune-suppressive myeloid cells depletion T Cells From “Cured” Mice Increase Survival in Adoptive Transfer Model “Cured” Mice Reject Re-Challenge of Same Tumor in Flank IMMUNE COMPETENT IMMUNE DEFICIENT CONTROL Adapted from Hiraoka et al., Neuro-Oncol. 2017.

Key Differentiators for Toca 511 & Toca FC in Brain Cancer Preclinical MOA, CR’s, OS data supported BTD and PRIME designations and peer-reviewed publications Notorious blood brain barrier mitigated with local Toca 511 delivery and precedent for 5-FC to treat brain fungus Multiple mechanisms support robust anti-cancer activity Consistent trial design from Phase 1 to Phase 3 (Toca 5)
