Synopsis
Self-assembling peptide-nucleotide (siRNA, mRNA) polyplexes avoid sequestration in liver, track to myriad pathologies, but do not distribute to tissues/organs with normal vascular barriers
Following cell uptake, the peptide moiety itself facilitates rapid and complete endosomal escape and KRAS siRNA release into cytoplasm to inhibit KRAS production
Peptide-nucleotide polyplexes are safe and stable in circulation, cleared by the kidney, and are not immunogenic after serial dosing

12:30 pm WT RAS Signalling is an Essential Therapeutic Target In RAS-Mutated Cancers
Synopsis

- Non-mutated (wild type) RAS family members activate RAS effectors that are activated poorly by mutated RAS
- Combined inhibition of mutated RAS and WT RAS signalling synergistically kills RAS-mutated cancers
1:00 pm Application of a quantitative systems pharmacology model to support differentiation of ASP2453, a novel KRASG12C inhibitor
Synopsis
- KRASG12C mutations lead to constitutive proliferation signaling and are prevalent across human cancers. Sotorasib, a KRASG12C inhibitor, was recently approved for the treatment of KRASG12C-mutated locally advanced or metastatic non-small cell lung cancer, and several other KRASG12C inhibitors are in clinical trials.
- ASP2453 is a novel, highly-potent, and selective inhibitor of KRASG12C. Will ASP2453 show a more favorable clinical response compared to its competitors?
- To address this question, we developed a quantitative systems pharmacology (QSP) model linking KRAS signaling to tumor growth. Virtual clinical trial simulations using the QSP model suggest ASP2453 will exhibit superior antitumor efficacy in patients, supporting potential differentiation and critical thinking for clinical trials.

Synopsis
- Using our PPI-disruption identifying platform, ToRPPIDO, we have discovered several new compounds that allosterically disrupt the Ras-Raf1 protein-protein interaction by binding Raf1 in a new pocket distal to its Ras Binding Domain
- STX200, a cell-permeable member of this set, exhibits a potent anti-proliferative activity against a variety of mutant RAS cancer lines
