Bispecific Antibodies

Enabling the next generation of ADCs

Synaffix is a one-stop provider for technologies required to rapidly translate antibodies into differentiated, proprietary ADC products.  The underlying platform ADC technology harnesses the power of the naturally-occurring glycan, present on all antibodies, as an anchor point to differentiate the efficacy and tolerability profiles of an ADC while improving manufacturability. When combined with the toxSYN™ ADC payload platform, Synaffix enables any company with an existing antibody to rapidly establish a highly-competitive clinical-stage ADC program for its own development pipeline.


We are critically focused on enabling our partners with the most advanced platform technology available for the design and development of site-specific ADCs that can be targeted against a wide variety of cancer types and can generate proof-of-concept ADCs in just a matter of weeks.

  • Key features of Synaffix ADC technology:
  • Consistently differentiated efficacy and efficacy
  • No need for mAb or cell line engineering
  • 4 different ADC payloads available
  • Homogenous and stable ADC products
  • Compatible with any IgG isotype and all key payload classes
  • Efficient conjugation of highly hydrophobic payloads
  • Significantly reduced aggregation potential
  • Tailored DAR: DAR2, DAR4 and Dual-Warhead (DAR2+2) ADC formats
  • Rapid and predictable scalability to multi-gram scale
  • COGs comparable to THIOmab ADCs
