Insights

Targeted radionuclide therapy (TRT) precisely delivers radiation to cancer cells. Research focuses on identifying cancer targets, developing selective targeting molecules, and utilizing optimal radionuclides for effective tumor treatment.

Area of Science:

  • Nuclear medicine
  • Radiopharmaceutical sciences
  • Oncology

Background:

  • Targeted radionuclide therapy (TRT) aims to deliver radiation effectively to cancer lesions while sparing healthy tissues.
  • Successful TRT relies on identifying cancer-specific targets, developing high-affinity targeting molecules, and selecting appropriate radionuclides.
  • The Center for Radiopharmaceutical Sciences (CRS) possesses unique infrastructure for radionuclide production and certified laboratories for radiopharmaceutical development.

Purpose of the Study:

  • To provide an overview of research activities at CRS in the field of TRT.
  • To highlight the development of novel radiopharmaceuticals for cancer therapy and diagnosis.
  • To showcase the translation of promising radiopharmaceutical candidates into clinical studies.

Main Methods:

  • Identification and characterization of cancer cell-specific targets.
  • Selection and optimization of targeting molecules (chemical or biological) with high affinity and selectivity.
  • Selection of radionuclides with suitable decay properties for therapeutic and diagnostic applications.
  • Preclinical evaluation using nuclear imaging equipment.
  • Preparation of drug samples in Swissmedic-certified laboratories for human use.

Main Results:

  • Exploration of non-standard radionuclides for tumor therapy and diagnosis.
  • Investigation and characterization of novel targeting structures.
  • Optimization of radiopharmaceutical properties for translational research.
  • Successful translation of promising candidates to 'first-in-human' studies through clinical collaborations.

Conclusions:

  • CRS is well-positioned to advance TRT due to its integrated infrastructure and expertise.
  • The research encompasses the full spectrum from target identification to clinical translation.
  • Collaborative efforts are crucial for bringing innovative radiopharmaceuticals to patients.
