A Study of 177Lu-FAP-2286 in Advanced Solid Tumors (LuMIERE)

Overview

About this study

The purpose of this study is to evaluate the safety and efficacy of [177Lu]Lu-FAP-2286 as monotherapy in participants with pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC), and breast cancer (BC) and in combination with chemotherapy in participants with untreated PDAC or relapsed NSCLC.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

participation or interfere with the interpretation of study results, and, in the opinion of
the investigator, would make the participant inappropriate for entry into the study.

to any reason (e.g., severe claustrophobia, inability to lie still for the entire imaging
