Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with at least one measurable extracranial lesion (RECIST 1.1) and appropriate ECOG status, across specified solid tumor types and HR/HER2 subgroups.

Probably not a fit

Patients with insufficient tumor uptake or contraindications to imaging may not benefit from the imaging results.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a Phase 1, open-label radioligand imaging study evaluating [68Ga]Ga-DWJ155 (FKL480) in adults with advanced gastroesophageal adenocarcinoma, HR+/HER2- or HER2+ advanced breast cancer, TNBC, and advanced NSCLC. The study plans to characterize biodistribution, tumor uptake, dosimetry, safety, and pharmacokinetics, and to identify optimal imaging time points. It consists of an imaging characterization part, with a potential expansion part if tumor uptake is positive. Each participant will undergo a single imaging day with up to 28 days screening, followed by safety follow-up for 3 days, for a total study duration of about 32 days per participant.

Why it matters

Potential benefit: If successful, imaging with [68Ga]Ga-DWJ155 could improve tumor visualization and help guide treatment decisions for patients with these cancers.

How similar studies have gone: Prior radioligand imaging studies have shown feasibility in characterizing biodistribution and tumor uptake, supporting further development in this class.
