H-11047: A Study of PS-341 Followed by Radical Prostatectomy for Patients With Adenocarcinoma of the Prostate (Spore #: 11-01-30-13)
In Brief
A Phase 2 clinical trial evaluating PS-341 (bortezomib) for Prostate Neoplasms. Completed, enrolled 40 participants across 1 site.
Detailed Summary
Following pretreatment evaluation, patients receive PS-341 by intravenous push weekly for 4 consecutive weeks followed by a 24-72 hour rest period. This schedule consists of one treatment cycle. Upon the completion of 4 weeks of PS-341 followed by a 24-72 hour rest period, radical prostatectomy will be performed. Surgery will be delayed if there is any bleeding abnormality (bleeding time greater than 10 minutes) and until platelet count is more than or equal to 100,000 and coagulation profile (PT, PTT) is normal. If at the time of surgery a patient is found to have positive lymph nodes, prostatectomy will be abandoned, the prostate will be biopsied, and the patient will be offered other treatment modalities (hormones, radiation therapy).

Interventions
PS-341 is a dipeptidyl boronic acid inhibitor with high specificity for the proteasome developed by Millennium Pharmaceuticals Inc. to treat human malignancies. It is the first member of this class of anti-tumor agents to come to human trials. Patients will receive PS-341 (1.6mg/m2/dose) by intravenous push weekly for 4 consecutive weeks followed by a 24-72 hour rest. This schedule consists of one treatment cycle. Upon the completion of 4 weeks of PS-341 followed by a 24-72 hour rest period, radical prostatectomy will be performed.
