NCT ID NCT05870579

First seen May 03, 2026 · Last updated May 16, 2026 · Updated 4 times

Summary

This early-phase study tests a new combination treatment for people with a certain type of advanced breast cancer (ER+, HER2-, GRPR+) that has stopped responding to standard hormone therapy. The treatment adds a targeted radiation drug ([177Lu]Lu-NeoB) to two existing hormone-blocking drugs (ribociclib and fulvestrant). The main goal is to find a safe dose and check for side effects in about 48 adults.
