ADNAB Partnership with Mayo Clinic1

A breakthrough proprietary next generation ADC platform

Based on work of Svetomir Markovic and colleagues at the Mayo Clinic2,3

Enables the binding of antibodies to drug payloads for oncology and beyond

Circumvents the need for:

  • Use of covalent “linker” technology
  • Internalization into the cell

Known, clinically active antibodies are non-covalently bound to drug payloads by construction of a patented admixture of

  • One or more therapeutically or immunologically active antibodies 
  • A “particle” of albumin
  • The drug payload

Investigator initiated proof of concept studies are ongoing in B cell lymphoma, melanoma, and gynecological cancers

Intellectual property portfolio comprised of 17 patent families, 32 patents granted to date with life through at least 2035 and another 135 patents pending.
