Brief summary (registry, in English)
This is a pilot study to assess the safety and measure image-based absorbed dose of 177Lu-P17-087/177Lu-P17-088 in patients with metastatic castration-resistant prostate cancer (mCRPC) who will undergo radioliagnd therapy using 177Lu-P17-087/177Lu-P17-088. All patients underwent whole-body 68Ga-PSMA PET/CT for selection and accepted intravenous injection with single dose 1.1 GBq (30 mCi) of 177Lu-P17-087/177Lu-P17-088 within one week, then monitored at 1.5 hours, 4 hours, 24 hours, 48 hours, 72 hours, 120 hours and 168 hours after 177Lu-P17-087/177Lu-P17-088 administration with serial whole body planar and SPECT/CT imaging.Following this initial safety assessment, the study will proceed to a dose-escalation phase designed to further evaluate safety and determine the optimal therapeutic activity. The dose-escalation phase will enroll patients into three sequential cohorts: a 1.11 GBq (30 mCi) dose group, a 2.96 GBq (80 mCi) dose group, and a 4.44 GBq (120 mCi) dose group.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Lab values
- Patients were excluded if they had \[18F\]FDG positive tumors without corresponding PSMA uptake. Patients were also not eligible if they accepted other radionuclide therapies within 6 months or had clinically significant impaired bone marrow, liver, or kidney function with a hemoglobin level of less than 9.0 g/dL, a white blood cell count of less than 2.5×109/L, a platelet count of less than 100×109/L and a serum creatinine \> 100 μmol/L.
Who the study is looking for
- All the patients had progressive metastatic castration-resistant prostate cancer that did not respond to androgen-suppression therapy and/or systemic chemotherapy;
- Distant metastases with high PSMA expression were confirmed on 68Ga-PSMA PET/CT within one week before the injection of 177Lu-P17-087/177Lu-P17-088.
