About RYZ101

RYZ101 is an investigational targeted radiopharmaceutical therapy, designed to deliver a highly potent radioisotope, Actinium-225 (Ac225), to tumors expressing SSTR2. RYZ101 is being evaluated in clinical studies for patients with SSTR+ GEP-NETs who have previously been treated with Lu177-based somatostatin therapies and also in patients with extensive stage small cell lung cancer. Details of the studies can be found at https://clinicaltrials.gov/ct2/show/NCT05477576 and https://clinicaltrials.gov/ct2/show/NCT05595460.

Ac225 for the study was provided by multiple sources including the U.S. Department of Energy Isotope Program.
