Summary

"This trial is testing a new treatment called 177Lu-PSMA-617 for patients with prostate cancer that has spread to other parts of the body and has not responded to treatment. The treatment works

Who is the study for?

This trial is for patients with prostate cancer that has spread and is resistant to treatment. Participants must have a specific low level of PSMA expression, which will be determined by scans.

What is being tested?

The study tests the effectiveness of an intensified dose of 177Lu-PSMA-617 in treating metastatic castrate-resistant prostate cancer (mCRPC). It involves various imaging techniques like bone scans, CTs, PET-CTs, SPECT, MRI, and biospecimen collection.

What are the potential side effects?

Potential side effects may include radiation exposure risks from the tracer used in imaging and treatment-related reactions such as nausea or fatigue. Specific side effects related to DNA damage within cancer cells are also possible.

Experimental Treatment

Group I: Treatment (177Lu-PSMA-617)Experimental Treatment8 Interventions

Patients receive 177Lu-PSMA-617 IV over 30 minutes on days 1, 8, 50, 57, 99 and 141. Treatment repeats every 7 days for cycles 1 and 3 and every 6 weeks for cycle 2 and subsequent cycles for up to 6 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo PSMA-PET/CT during screening and SPECT/CT on study. Patients also undergo CT or MRI, bone scan, as well as blood sample collection throughout the study.
