Docetaxel and Diethylstilbestrol in the Treatment of Androgen Independent Prostate Cancer

2014-08-27 03:52:14 | BioPortfolio

Summary

This study is for men who have prostate cancer that has spread outside of the prostate gland and is no longer responding to hormone removal therapy. This study is designed to determine if a new drug combination will help to control the cancer. The medicines being used, docetaxel and diethylstilbestrol (DES), have been given to patients with prostate cancer and each drug has demonstrated activity in prostate cancer, either used alone or in other combinations. The objective of this study is to determine the effect of this drug combination on the prostate cancer and its response to disease progression.

Description

This is a single arm phase II trial of docetaxel and diethylstilbestrol for patients with symptomatic stage D3 androgen independent prostate cancer. Patients will receive docetaxel weekly for 10 cycles (each cycle consists of treatment for 3 weeks out of every 4) and DES daily for 40 weeks or until there is evidence of disease progression, whichever occurs first. Patients will be followed to determine PSA and objective response. Additional endpoints include time to progression, disease specific survival and overall survival. Disease progression will be defined as 2 consecutive increases in PSA and/or tumor growth as evidenced by examination or radiologic evaluation. Other secondary objectives will be to determine the toxicity, and impact on quality of life of this regimen.

A randomised phase II trial of docetaxel versus docetaxel plus carboplatin in patients with castration-resistant prostate cancer who have progressed after response to prior docetaxel chemotherapy: The RECARDO trial.

Docetaxel is standard first-line chemotherapy for patients with metastatic castration-resistant prostate carcinoma (mCRPC). Docetaxel re-challenge has never been tested in a prospective randomised con...

Cdc20/p55 mediates the resistance to docetaxel in castration-resistant prostate cancer in a Bim-dependent manner.

At least to date, no effective treatment for advanced castration-resistant prostate cancer (CRPC) has been established. Recent studies indicated that cell division cycle 20 homolog (Cdc20) overexpress...

The evolution of chemotherapy for the treatment of prostate cancer.

Chemotherapy has been explored as a treatment option for metastatic prostate cancer since the early 1980s. Docetaxel, a taxane chemotherapeutic, was approved for the treatment of men with metastatic c...

Treatment with docetaxel in combination with Aneustat leads to potent inhibition of metastasis in a patient-derived xenograft model of advanced prostate cancer.

Docetaxel used for first-line treatment of advanced prostate cancer (PCa) is only marginally effective. We previously showed, using the LTL-313H subrenal capsule patient-derived metastatic PCa xenogra...

microRNA-323 upregulation promotes prostate cancer growth and docetaxel resistance by repressing p73.

Our previous work has demonstrated that miR-323 enhances tumor angiogenesis in prostate cancer. In the present study, we sought to determine the function of miR-323 in prostate cancer cell growth and ...

Medical and Biotech [MESH] Definitions

A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.

A synthetic nonsteroidal estrogen used in the treatment of menopausal and postmenopausal disorders. It was also used formerly as a growth promoter in animals. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), diethylstilbestrol has been listed as a known carcinogen. (Merck, 11th ed)

A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.

Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).

Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
