Bubendorf, Switzerland, Tuesday, July 10, 2018 – Over the course of the past months, CIS Pharma has developed concepts and strategies to conjugate radioisotopes onto its polymer-drug carriers. First syntheses results and tests with cold substances are promising and CIS Pharma is proactively searching for scientific collaborations in the field of antibody-radionuclide conjugates, nuclear oncology respectively.
About CIS Pharma antibody-drug conjugates, ADCs, and antibody radionuclide conjugates, ARCs
ADCs, antibody-drug conjugates, are a class of highly potent drugs for the treatment of cancer. Conventional ADCs are composed of a chemotherapeutic drug that is conjugated directly to an antibody targeting cancer cells. CIS Pharma has developed a polymer-drug-carrier, PDC, that is loaded with anticancer moieties and consequently linked to the antibody. The PDC platform allows for customization and optimization of ADCs for a given target and indication.
ARCs, antibody-radionuclide conjugates, are a form of radiotherapy, where a radionuclide molecule is linked to an antibody. CIS Pharma has developed a radionuclide-specific PDC that is optimized to conjugate radionuclides to an antibody. Radionuclides, such as Lutetium-177 or Iodine-131 are radioactive isotopes that emit radiation that kill cancer cells. Other radionuclides such as Indium-111 or Zirconium-89 are used for imaging and localization of cancer cells and to monitor the progress of cancer treatment.
Theranostics is a concept that refers to the integration of imaging and therapy in a single system, allowing therapy and follow-up of the treatment. CIS Pharma PDC’s are designed to conjugate both imaging and therapeutic compounds in a single system to simultaneously treat and monitor cancer. Alternatively, the identical antibody-polymer-drug-carrier-system is loaded in a first step with imaging radio-isotopes to then load in a second run therapeutic radio-isotopes to treat cancer.
