Docetaxel, Bevacizumab and Androgen Deprivation Therapy for BCR After Definitive Local Therapy for Prostate Cancer

Prostate Cancer Clinical Trial

Official title: A Phase II Trial of Avastin, Docetaxel and Androgen Deprivation Followed by Continued Avastin and Androgen Deprivation for Men With a Rising Prostate Specific Antigen (PSA) After Local Therapy

Status Completed

Clinical Trial Summary

In this research study, we aim to evaluate the feasibility, toxicity and efficacy of early multimodality systemic therapy (a combination of docetaxe, bevacizumab, and androgen deprivation therapy(ADT) in men with biochemical recurrence (BCR) or who have a rising PSA after treatment of their prostate cancer with surgery or radiation)

Clinical Trial Description

A single arm phase 2 study designed to evaluate the rate of patients free from PSA progression (TTP) one year after completing ADT for men with BCR after definitive local therapy for prostate cancer.

The null and alternative TTP rate were 41% and 60% respectively. A sample size of 42 would provide 80% power to detect the difference with a 2-sided type I error rate of 0.05.'

The primary objective was to evaluate the proportion of patients free from PSA progression after completing one year of ADT

The secondary objectives included

1. PSA response (< 0.2 ng/mL and < 0.01) at completion of docetaxel/bevacizumab, at completion of ADT and one year off ADT

2. Correlation of PSA response and TTP

3. Toxicity

4. Testosterone recovery at 6, 12 months off ADT

Treatment schedule details are as follows:

• Each treatment cycle lasts three weeks. During the first three months, participants will receive the Avastin and docetaxel on day 1 of each three-week cycle for a total of four doses of docetaxel/Avastin. Avastin and docetaxel are administered intravenously. The Avastin will continue to be given every three weeks after the docetaxel is completed for a total of 17 doses (one year) of Avastin therapy.

• Participants will receive zoladex (or lupron) on day 1 of the first cycle and then every 3 months for a total of 18 months. Zoladex is administered subcutaneously and Lupron is administered intramuscularly.

• Bicalutamide pills will be started at the completion of docetaxel chemotherapy (start of month 4) and will be taken once daily until hormone therapy is completed (total of 15 months).

• During all treatment cycles, the participant will have a physical exam and will be asked questions about their general health and specific questions about any problems they might be experiencing. Blood work will be performed every three weeks for the first three months and then every three months while on hormone therapy and during follow-up.

• After the final treatment participants will have a follow-up visit every three months for the first two years, every 4 months for the third year and every 6 months for years 4 and 5. ;
