Clinical trial Recruiting at 3 sites Phase 1 Interventional Ages 18 and up Men only

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.

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

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.
