Our technology

Avidea’s polymer-drug conjugate (PDC) platforms overcome key hurdles for enabling successful immunotherapies. Learn more


  • Modular vaccine capable of co-delivering any antigen(s) and immunomodulator(s) in self-assembling nanoparticles with precise size and composition
  • Most efficient T cell priming platform reported to-date
  • Applications: cancer, autoimmunity and infectious diseases


  • Synthetic, virus-sized star polymer combines direct tumor killing with immune stimulation, akin to oncolytic viruses, without the drawbacks
  • Dual responsive properties for targeted accumulation and selective drug release in tumor
  • Applications: metastatic tumor targeting


  • Nanoparticle formation occurs after injection thereby trapping drug in tissues where it is needed
  • Reduces dosing frequency in volume restricted tissue
  • Applications: retains drugs in the eye, CNS and joints
