Cristal Therapeutics Publishes Positive Data on its CriPec® Nanomedicine Technology in Small

  • Small publication demonstrates that superior therapeutic profiles of CriPec® nanomedicines result from rational design

Maastricht, The Netherlands, 11th May 2020 – Cristal Therapeutics, a Phase 2 clinical-stage pharmaceutical company developing targeted nanomedicines for the treatment of cancer and other diseases with high unmet patient need, announces the publication of a paper on its CriPec® nanomedicine technology in the high-impact journal Small.

The research1, reports the results of a collaboration between Cristal Therapeutics and Mainz and RWTH Aachen Universities, Germany. Current understanding indicates that when nanoparticles are introduced into a living organism, they rapidly adsorb proteins to form a corona, which thereafter determines their fate in the body. This research however shows that when CriPec® nanoparticles are exposed to plasma, they form a negligible protein corona.

This is a significant result. It demonstrates that the superior biological properties of CriPec® nanoparticles, such as prolonged circulation and improved pharmacokinetics, are due to rational design rather than patient-related factors. This also explains the inter-patient invariability in pharmacokinetics observed for CriPec® technology in the clinic, which is the basis for the improved tumour targeting and therapeutic profile of CriPec® nanomedicines.

Dr Cristianne Rijcken, CSO of Cristal Therapeutics said: This elegant study demonstrates that the superior biological profiles of our CriPec® nanoparticles are the result of optimal pharmaceutical composition, not interaction with biological compounds after administration. On this understanding, we are able to rationally design CriPec® nanomedicines targeting specific indications. Combined with our straightforward manufacturing process, this creates multiple new product opportunities.”
