Treating metastatic prostate cancer with [177Lu] Lu-PSMA-XT injection
Official title: A Phase I Study to Assess the Safety, Tolerability, Radiation Dosimetry and Efficacy of [177Lu] Lu-PSMA-XT in Patients With Metastatic Prostate Cancer
Run by Chinese PLA General Hospital · NCT07096128 · Data updated 2026-11-12
This trial tests a radioactive PSMA-targeting injection called [177Lu] Lu-PSMA-XT in men with metastatic castration-resistant prostate cancer to see if it is safe, tolerable, and can help control the cancer.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are men with progressive metastatic castration-resistant prostate cancer who are PSMA-PET positive, have castrate-level testosterone, ECOG 0–1, are aged 18–80, have prior novel antiandrogen therapy and one to two taxane regimens (or are unsuitable for taxanes), and have life expectancy over six months.
✕Probably not a fit
Patients with PSMA-negative disease, poor performance status (ECOG ≥2), very limited life expectancy, or contraindications to radioligand therapy are unlikely to benefit from this intervention.

What this trial studies
This multicenter, open-label Phase 1 study gives [177Lu] Lu-PSMA-XT to men with progressive mCRPC who are PSMA-PET positive and meet enrollment criteria including castrate testosterone and ECOG 0–1. The primary focus is on safety, tolerability, and radiation dosimetry, with secondary observation of early anti-tumor activity across dose levels. Enrolled patients typically have received prior novel antiandrogens and one to two taxane regimens or are deemed unsuitable for taxanes; dosing schedules and follow-up visits are defined in the protocol. Participants will undergo imaging, laboratory testing, and clinical exams to monitor radiation exposure, adverse events, and tumor response.
Why it matters
Potential benefit: If successful, this targeted radioligand could deliver radiation directly to PSMA-expressing cancer cells and potentially shrink tumors or slow disease progression with manageable side effects.
How similar studies have gone: Other Lu-177 PSMA radioligand therapies (for example [177Lu]Lu-PSMA-617) have shown meaningful clinical benefit in mCRPC, so the general approach has clinical precedent though this specific agent is early-stage.
