Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with metastatic castration-resistant prostate cancer who have failed standard treatments and have at least one measurable lesion, ECOG 0-1, and adequate organ function.

Probably not a fit

Patients with significant comorbidities, rapidly progressing disease, or those who do not tolerate the treatment regimen may not benefit.

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 early-phase, single-arm, open-label, dose-escalation study in adults with metastatic castration-resistant prostate cancer. Five predefined dose groups are evaluated, with treatment given every 6 weeks for up to four cycles. After each dose group completes enrollment and observes safety, radiation dosimetry, and preliminary efficacy, the next group's dose may be adjusted or escalation stopped. The goal is to establish safety, determine dosimetry, and obtain initial signals of efficacy for Lu-177 FC516. Participants must meet specific laboratory and performance criteria and have at least one measurable lesion per RECIST 1.1.

Why it matters

Potential benefit: If successful, patients could receive a novel radiopharmaceutical therapy that delivers targeted radiation to prostate cancer lesions.

How similar studies have gone: Prior studies of targeted radioligand therapies in prostate cancer have shown safety signals and potential activity, supporting continued exploration in this approach.
