Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This is a phase I dose-escalation study of 225Ac-J591 administered together with 177Lu-PSMA small molecule. Both drugs are designed to deliver radiation to prostate cancer cells; they are known as radionuclide conjugates (radiation linked to antibodies/molecules that recognize prostate cancer cells). This phase of the study (phase I) will determine the highest dose of the study intervention that can be safely given.
