Study Summary

This trial tests if experimental drugs are safe and effective against cancer in humans for the first time.

Who is the study for?
This trial is for adults with certain advanced solid tumors, including pancreatic, colorectal, prostate, stomach cancers and more. Participants must have a tumor that can be measured by RECIST v.1.1 criteria and express NTSR1 as confirmed by imaging after [111In]-FPI-2058 injection. They should have an ECOG performance status of 0 or 1 (fully active or restricted in physically strenuous activity but ambulatory), adequate organ function, and no effective standard therapy options left.Check my eligibility
What is being tested?
[225Ac]-FPI-2059 and [111In]-FPI-2058 are being tested for safety, tolerability, how the body processes them (pharmacokinetics), and where they go in the body (biodistribution) in patients with solid tumors expressing neurotensin receptor 1. This first-in-human Phase 1 trial aims to find out if these treatments are safe to use and how they affect participants' bodies.See study design
What are the potential side effects?
As this is a first-in-human study testing new compounds ([225Ac]-FPI-2059 & [111In]-FPI-2058), specific side effects aren't fully known yet but may include typical reactions related to radiopharmaceuticals such as nausea, fatigue, potential organ toxicity or allergic reactions.
