Docetaxel/Prednisone Plus Fractionated 177Lu- J591 Antibody for Metastatic, Castrate-resistant Prostate Cancer

Phase 1
Completed
Conditions
Prostate Cancer
Interventions
Registration Number
NCT00916123
Lead Sponsor
Weill Medical College of Cornell University
Brief Summary

The purpose of this study is to test the effectiveness of the experimental drug, 177Lu-J591 antibody in combination with docetaxel chemotherapy against metastatic, castrate-resistant prostate cancer.

Detailed Description

This research is being done because the standard treatments for metastatic prostate cancer that is growing despite medical or surgical therapies are not curative. Existing treatments, such as the docetaxel used as part of this study, may work temporarily, but unfortunately the cancer continues to grow. This test drug, 177Lu-J591, is designed to seek out prostate cancer cells and deliver a lethal dose of radiation to the areas of cancer, but not to normal areas. Some of the normal organs (liver, kidney and bone marrow) do receive some radiation dose that is within the acceptable limits.

Inclusion Criteria
  • Histologic diagnosis of prostate adenocarcinoma.

  • Patient must have progressive metastatic prostate cancer despite adequate medical or surgical castration therapy.

  • Serum testosterone < 50 mg/ml.

  • Patients who have previously received docetaxel must meet BOTH of the the following criteria:

    • reason for docetaxel discontinuation must NOT have been progression of disease while receiving drug (i.e. progression of cancer must have been AFTER docetaxel discontinuation) AND
    • All docetaxel-related toxicities must have resolved to < grade 1 (with the exception of alopecia) and the pt must be eligible by other criteria
