It's All about the Antibody Glycan

GlycoConnect™ replaces the existing antibody glycan with a therapeutic payload. Synaffix has established a simple, yet powerful, clinical-stage platform technology enabling best-in-class ADCs, bispecific antibodies and the targeted delivery of various other therapeutic payloads, all without modifying the antibody sequence.

Building from of the well-understood cellular targeting abilities of antibodies, we combine the intrinsic efficiency of enzymes with the unique specificity of metal-free click chemistry to replace the native antibody glycan with a stably attached therapeutic payload.

By combining GlycoConnect™ with our other complementary technologies, Synaffix has consolidated all necessary technologies required for proprietary, best-in class ADCs as well as bispecific antibodies.

Following millions of years of evolution, the native glycan was retained in a similar position on all antibodies and GlycoConnect™ is built entirely around this.

Enabling best-in-class, all under one roof

Technology & How We Differentiate

  • GlycoConnect™ enables best-in-class therapeutic efficacy and tolerability
  • HydraSpace®
    further differentiates efficacy and tolerability versus other site-specific ADC approaches
  • toxSYN®linker-payloads provide multiple options to maximize efficacy in light of tumor biology
  • Proprietary DAR1 technology 
  • Protected by worldwide patent estate, consisting of 25+ patents

How It Works

GlycoConnect™ Antibody-Drug Conjugation

Any antibody can be converted into a stably conjugated ADC in just a few days by modifying the native antibody glycan using our highly efficient enzymes and metal-free click chemistry approach.

Multiple independent experiments confirm that the native glycan position is likely one of the best for attaching ADC payloads to antibodies.

Bispecifics

Enabling immune cell engagers & other protein conjugates

Technology & How We Differentiate

  • Novel 2:1 format expected to deliver safety advantage
  • Avoid co-expressing a genetic fusion of two separate antibodies / binding domains
  • Directly convert any off-the-shelf antibody into a bispecific

How It Works

Non-genetic Approach to Bispecifics

We use GlycoConnect™ to conjugate a separate antibody binding domain or cytokine (similar to an ADC payload), enabling bispecific immune cell engagers or checkpoint inhibitors from full-sized antibodies.
