What this Trial Is About

This study aims to determine the safety, pharmacokinetics (PK) and recommended Phase 3 dose (RP3D) of RYZ101 in Part 1, and the safety, efficacy, and PK of RYZ101 compared with investigator-selected standard of care (SoC) therapy in Part 2 in subjects with inoperable, advanced, well-differentiated, somatostatin receptor expressing (SSTR+) gastroenteropancreatic neuroendocrine tumors (GEP-NETs) that have progressed following treatment with Lutetium 177-labelled somatostatin analogue (177Lu-SSA) therapy, such as 177Lu-DOTATATE or 177Lu-DOTATOC (177Lu-DOTATATE/TOC), or 177Lu-high affinity \[HA\]-DOTATATE.
