Who may be able to join

  • Patients must be males, at least 18 years of age, with pathologically confirmed adenocarcinoma of the prostate
  • Patients must have evidence of androgen-independent metastatic prostate cancer (AIMPC) following standard antiandrogen withdrawal. AIMPC will be defined as the category of patients with metastatic prostate cancer with radiologic evidence of metastases (bone scan, CT, etc.) and castrate levels of testosterone (~ 50 ng/dL).
  • All patients must be receiving ongoing therapy to ensure testicular androgen suppression (LHRH agonists therapy or bilateral orchiectomy).
  • All patients receiving anti-androgen therapy [e.g., flutamide (Eulexin), bicalutamide (Casodex), or nilutamide (Nilandron)] must have initiated therapy at least 3 months (90 days) prior to the Baseline visit.
  • Patients must have received prior docetaxel-based or mitoxantrone-based chemotherapy, or refused or been ineligible for chemotherapy. Previous chemotherapy treatments must be completed at least 4 week prior to Screening, and patients must not have any residual therapy-related toxicities present at Screening.
  • Patients must have evidence of disease progression defined as any of the following:

About this study

Official title: An Open-Label, Phase II Safety, Tolerability, Drug Level and Efficacy Trial of Quinacrine in Patients With Androgen-Independent Metastatic Prostate Cancer

The purpose of this study is to determine whether quinacrine is effective in the treatment of Androgen-Independent Prostate Cancer.

Read the detailed description

Despite a modest improvement in survival with available chemotherapy treatments, androgen-independent metastatic prostate cancer remains essentially incurable.

Several changes in gene function that characterize malignancy have been identified. For example the p53 gene in normal tissue lessens the risk of cancer through growth arrest or cell suicidal programs. Thus the silenced p53 gene present in cancer tissue contributes to the growth of the cancer. In addition when the p53 gene is silenced, a cell survival pathway, controlled by the NF-kB gene, is activated leading increased cell survival.

Quinacrine can activate p53 and inhibit NF-kB, thus reestablishing cell suicidal programs and decreasing cell survival in cancer tissue. Moreover, quinacrine is effective against several prostate tumor cell lines in vitro, and has anti-tumor effects against prostate cancer xenografts in mice.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Efficacy of Quinacrine, Based on Prostate Specific Antigen (PSA) Response in Patients With Androgen-independent Metastatic Prostate Cancer

    Patients who achieved a complete response (CR) or a partial response (PR) to therapy were allowed to continue to receive treatment until disease progression or unacceptable toxicity occurred, until the patient discontinued treatment for another reason, or for a total of 6 months. Patients who continued to show a CR or PR or who maintained stable disease (SD) after 6 months of therapy were to be allowed to continue therapy at the investigator's discretion.

    Measured: End of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Quinacrine in people with Prostatic Cancer, run by Cleveland BioLabs.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 17 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 11 Apr 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Efficacy of Quinacrine, Based on Prostate Specific Antigen (PSA) Response in Patients With Androgen-independent Metastatic Prostate Cancer (time frame: End of treatment). 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 NCT00417274, which also lists 1 linked publication.

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 11 Apr 2013.
