#2 Radioligand Therapy (RTL) Drug Approval for “See & Treat”
Oncology Advancements: Top 10 of 2022
Clinical trials showed a 38% increase in survival in PSMA-positive metastatic castration-resistant prostate cancer patients (who had been treated with AR pathways & taxane-based chemotherapy)[2].
Why is this significant?
RTL offers the promise of “see and treat”, while also being less invasive and sparing normal tissue.
RTL has the potential to combine different kinds of radioactive atoms and targeting molecules together. By combining a radioactive atom that can identify the tumors location with a therapeutic that is armed to damage the tumor cell, new combinations can be used for expansion of ”see and treat” therapy.
What is RTL?
Nuclear medicine has both diagnostic imaging and therapeutic components, called radioligand imaging and radioligand therapy. Both use the same targeting approach. The diagnostic imaging component delivers radioactive atoms that have the potential to reveal tumor locations, while the therapeutic component delivers radioactive particles that have the potential to damage cells.
