ESMO 2025 | Future of theranostics and PRRT in oncology treatment strategies

Aman Chauhan, MD, Sylvester Comprehensive Cancer Center, Miami, FL, comments on the future potential of theranostics in oncology, particularly in the context of peptide receptor radionuclide therapy (PRRT). PRRT combination studies, including the use of radiosensitizers, will have a more prominent role in various tumor types, such as neuroendocrine tumors (NETs) and prostate cancer, both in de novo patients and those who have progressed on prior PRRT. This interview took place at the European Society for Medical Oncology (ESMO) 2025 Congress in Berlin, Germany.

Transcript

Well, theranostics is a very hot topic in oncology and there is a lot of drug development happening in the theranostics space. While there is a lot of excitement about alpha PRRT, which is crowding the space, we have a lot of safety and comfort with the existing beta PRRT agent like lutetium 177-dotatate. So my personal research endeavors are focusing on building on the success of lutetium 177-dotatate and adding scientifically sound radiation sensitizers to boost the efficacy without jeopardizing the safety...

Well, theranostics is a very hot topic in oncology and there is a lot of drug development happening in the theranostics space. While there is a lot of excitement about alpha PRRT, which is crowding the space, we have a lot of safety and comfort with the existing beta PRRT agent like lutetium 177-dotatate. So my personal research endeavors are focusing on building on the success of lutetium 177-dotatate and adding scientifically sound radiation sensitizers to boost the efficacy without jeopardizing the safety. So those are our goals. And what I foresee in the near future, there is a big room to incorporate these PRRT combination studies, not just in NETs, you know, as these theranostics agents kind of spread their swing and up when prostate cancer is a big, big indication and several other tumor types, we are investigating radiopharmaceutical drugs. I think the addition of smart radio sensitizers, which don’t affect the safety profile, but significantly boost the potential efficacy, I think will be the next wave of theranostic studies. So I foresee both in de novo patients where there is a role for PRRT and as well as in re-treatment patients where patients have previously progressed on PRRT and now need to be re-challenged with PRRT. I think there’s a role for combination studies and radiosensitizers in that space.
