Recruiting at 1 site Phase 1 Metastatic Prostate Cancer

Clinical trial for Metastatic Prostate Cancer

Official title 177Lu-PSMA-617 With Liver Directed Therapy in Metastatic Castration Resistant Prostate Cancer

ClinicalTrials.gov ID: NCT07145177

What this study is testing

What is 177Lu-PSMA-617?

An investigational intravenous drug being studied for metastatic prostate cancer. is designed to target prostate-specific membrane antigen (PSMA) on cancer cells and deliver radioactive radiation to kill them.

Also referred to as Lutetium-177 (177Lu)-PSMA-617.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study aims to find out whether giving 177Lu‑PSMA‑617 after liver‑directed therapy is safe for patients with advanced prostate cancer that has spread to the liver.
Who it's for
Men with metastatic castration‑resistant prostate cancer that has spread to the liver and who have already tried at least one androgen‑pathway drug.
What's involved
Participants will receive the 177Lu‑PSMA‑617 treatment and a liver‑directed therapy, and will be monitored for side effects and safety.
Time commitment
Participants will attend scheduled visits for treatment and safety monitoring as directed by the study.

  • Prior progression on at least one second generation androgen signaling inhibitor including abiraterone, apalutamide, darolutamide, and/or...

You likely can't join if

  • Prior progression on at least one second generation androgen signaling inhibitor including abiraterone, apalutamide, darolutamide, and/or enzalutamide.
  • Adverse events related to prior anti-cancer treatment (excluding LHRH analogs) must have recovered to Grade ≤ 1 (except for any grade alopecia and grade ≤ 2 neuropathy).
  • Prior external beam radiotherapy is allowed if the last radiotherapy treatment was greater than 2 weeks from start of study treatment on Cycle 1 Day 1 (C1D1).
  • At least one PSMA-avid extrahepatic lesion on screening PSMA Positron Emission Tomography (PET). A positive lesion is defined as uptake above background liver. Hepatic lesions may be PSMA PETnegative or positive.
  • Availability of archival mCRPC tissue, or presence of a metastatic lesion that is amenable to fresh biopsy and willingness to undergo biopsy during screening if no archival mCRPC tissue available.
  • The presence of one or more liver metastases amenable to liver-directed therapy in the judgment of the treating treatment radiologist.
  • Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 or Karnofsky ≥ 50%.

  • Total bilirubin ≤ 2 x upper limit of normal (ULN). In participants with known or suspected Gilbert's disease, direct bilirubin ≤ ULN.
  • aspartate aminotransferase (AST)/serum glutamic-oxaloacetic transaminase (SGOT) ≤ 5 x institutional upper limit of normal.
  • alanine aminotransferase (ALT)/serum glutamic-pyruvic transaminase (SGPT) ≤ 5 x institutional upper limit of normal.
  • Prothrombin time ≤ 1.5 x institutional upper limit of normal (unless on medical therapy known to prolong prothrombin time).

  • Participants must use appropriate methods of contraception during study treatment and for at least 6 months after last study treatment.
  • Ability to understand and the willingness to sign a written informed consent document.
What rules you out
  • De novo small cell neuroendocrine prostate cancer.

  • Recipient of more than one cycle of PSMA-directed radioligand treatment. Up to one treatment cycle is allowed prior to study enrollment.
