Rhea-AI Summary

CytomX Therapeutics and Moderna have unveiled promising preclinical data for their collaborative development of an mRNA-encoded masked IL-12 molecule at the AACR Annual Meeting in Chicago.

The breakthrough combines CytomX's PROBODY® masking technology with Moderna's mRNA expertise to create a novel cancer treatment approach. The key innovation lies in developing an IL-12 therapeutic that can be selectively activated within the tumor microenvironment while minimizing systemic activity.

Key highlights:

  • Successfully demonstrated proof of concept for mRNA encoded masked molecule in cancer treatment
  • Achieved enhanced tolerability while maintaining anti-tumor efficacy
  • Addresses previous limitations of IL-12's clinical use due to inflammatory toxicity

The research findings will be presented in Poster #3127/12 on April 28, 2025, highlighting how this innovative combination of technologies could potentially overcome traditional IL-12 therapy limitations.
