Our Science

Predator® Protein Engineering

Our proprietary PREDATOR® protein-engineering technology allows us to achieve immune targeting and conditional activation in a new way, enabling the development of novel therapies designed to:
1
HP-icon-1-static-blue
Exhibit superior tolerability and drug-like properties when administered systemically as inactive pro-drugs
2
HP-icon-2-static-blue
Undergo transformation to the active state only upon reaching the tumor microenvironment
3
HP-icon-3-static-blue
Deliver full biological potency of antitumor immune modulation for maximum therapeutic potential

TRANSFORMING CANCER TREATMENT THROUGH INNOVATION

Our proprietary PREDATOR® protein-engineering technology integrates specialized protein design elements to enhance activity, stability, and tumor
selectivity within a single molecule. Our conditionally-activated cytokines are called INDUKINE™ molecules.

Protease-cleavable linkers

INDUKINE™ molecules are systemically administered in an inactive form and, upon entering the tumor microenvironment, are selectively activated to deliver the full biological potency of cytokines and recruit a powerful anti-tumor immune response. Therefore, INDUKINE™ molecules deliver maximum therapeutic potential while minimizing unwanted off-target effects in non-tumor tissues.

INDUCER Molecules: Next-Generation Conditionally Activated T Cell Engager Design

  • Proprietary and optimized anti-CD3 masking technology to reduce systemic toxicity and off-tumor effects
  • Novel Pan-cancer Linker acts as tumor-specific switch, enabling precise unmasking and conditional activation and off-tumor effects
  • Novel anti-CD3 Ab optimized for developability
  • Tumor-associated antigen binding domain selected for optimal immune cell engagement
  • Tumor targeting mask when target has more extensive expression in normal tissues
  • Proprietary anti-HSA VHH for half-life extension & increased tumor exposure
Harnessing powerful masking technology and clinically validated pan-cancer linker to improve therapeutic index

INNOVATIVE OPPORTUNITIES FOR PREDATOR® PLATFORM

In addition to our core commitment to oncology, our PREDATOR® approach allows us to target other immunology-based diseases.

Our PREDATOR® protein-engineering technology allows us to create INDUKINE™ molecules for tissue-specific inflammatory diseases where modulating the immune system can offer therapeutic benefits while minimizing unwanted off-target effects in healthy tissues.
