Gene Mutations in Patients With Advanced Prostate Cancer That Is Not Responsive to Hormone Therapy
An observational study of Prostate Cancer, run by Alliance for Clinical Trials in Oncology at 49 sites in United States.
Trial summary
RATIONALE: Gene mutations may make prostate cancer cells unable to attach to androgens. This may permit the growth of prostate cancer. Gene testing may improve the identification of patients with advanced prostate cancer. Read more about this study

Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages Any age
- Men only
- No healthy volunteers
- Child, Adult, Older adult
Study population: Eligible men enrolled on a trial of antiandrogen withdrawal had a minimum prostate-specific antigen (PSA) level of 5 ng/dL that was increasing on castration therapy including an antiandrogen. Marrow biopsies were obtained to collect prostate tumor. Additional samples were obtained from men enrolled on chemotherapy trials.
- Histologically proven adenocarcinoma of the prostate that is refractory to hormone therapy
- Patients who are eligible for anticancer therapy on Protocol CLB-9480, CLB-9583, CLB-9680, or CLB-9780 are also eligible for this study if they have not started treatment on those protocols

| Study group | Role | What they receive |
|---|---|---|
| Source of patient samples | The CALGB conducted a phase III study (CALGB 9583) in which 260 men with AiPC were randomly assigned to antiandrogen withdrawal together with simultaneous ketoconazole and hydrocortisone versus antiandrogen withdrawal alone, followed by sequential ketoconazole and hydrocortisone. Metastatic disease with progression despite castrate levels of testosterone, prior antiandrogen therapy for a minimum of 4 weeks, and a minimum PSA level of 5 ng/mL were required; treatment with sequential antiandrogens was allowed. No prior chemotherapy was allowed. Bone marrow biopsies were obtained from 164 patients enrolled on CALGB 9583 and from 20 patients enrolled on CALGB chemotherapy trials (CALGB 9480, 9680, 9780).

Questions about this trial
What is this clinical trial studying?
An observational study of Prostate Cancer, run by Alliance for Clinical Trials in Oncology at 49 sites in United States.
The full registered description is in the About this study section and the official record.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 14 Jul 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 49 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
overall survival (time frame: Up to 10 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00002924, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jul 2016; AzTrials last refreshed its copy on 6 Nov 2026.
