About this study

Official title: A Phase II Trial of STA-9090 in Patients With Metastatic Castration-Resistant Prostate Cancer (CRPC) Pretreated With Docetaxel Based Chemotherapy

Hsp90 inhibitor STA-9090 may stop the growth of tumor cells by blocking some of the proteins needed for cell growth. This phase II trial is studying how well Hsp90 inhibitor STA-9090 works in treating patients with metastatic hormone-resistant prostate cancer previously treated with docetaxel-based chemotherapy

Read the detailed description

PRIMARY OBJECTIVES:

  1. To evaluate progression-free survival (PFS) achieved with STA-9090 (Hsp90 inhibitor STA-9090) in men with castration-resistant prostate cancer (CRPC) who have received prior docetaxel based therapy.

SECONDARY OBJECTIVES:

  1. To assess the percentage change in prostate-specific antigen (PSA) from baseline to 12 weeks.

II. To assess overall safety and tolerability of STA-9090. III. To evaluate overall survival (OS) outcome in metastatic CRPC who have received prior docetaxel therapy.

IV. To investigate the association of progression-free survival (PFS) and PSA response rate with primary and secondary target markers.

TERTIARY OBJECTIVES:

  1. To evaluate potential markers for predicting drug response or efficacy, blood samples will be used to collect the serum and extract messenger ribonucleic acid (mRNA) from mononuclear cells and analyzed by quantitative real-time polymerase chain reaction (PCR) and/or enzyme-linked immunosorbent assay (ELISA).

OUTLINE:

Patients receive Hsp90 inhibitor STA-9090 intravenously (IV) over 1 hour once weekly in weeks 1-3. Courses repeat every 4 weeks in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 4 weeks.

Being tested

What is being measured

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

  1. PFS Proportion Achieved With STA-9090 in Men With CRPC Who Have Received Prior Docetaxel Based Therapy

    Our primary objective was to determine the 6-month PFS rate by using a binary (yes/no) endpoint of 6 months of PFS. Treatment success was defined as achievement of at least 6 months of PFS. Patients who did not complete 6 months of ganetespib therapy for any reason (including death from any cause) were considered treatment failures and were recorded as not achieving the primary endpoint.

    Measured: At 6 months

Secondary outcomes (5)
  1. Percentage Change in PSA

    Percentage change in PSA from baseline.

    Measured: From baseline to 12 weeks

  2. Overall Safety and Tolerability of STA-9090

    Overall safety and tolerability of STA-9090 by total number of grade 3 adverse events

    Measured: Day 1, 8, and 15 of each course and at end of treatment

  3. OS in Metastatic CRPC Who Have Received Prior Docetaxel Therapy

    Overall Survival (OS) in metastatic Castrate Resistant Prostate Cancer (CRPC) who have received prior docetaxel therapy using Kaplan-Meier method

    Measured: From first dose to death or the date last known alive

  4. Association of PFS With PSA

    Association of PFS with PSA using Cox PH regression model

    Measured: At 6 months

  5. Potential Markers for Predicting Drug Response or Efficacy

    Potential markers for predicting drug response or efficacy : This is not a measurable outcome, but a possible entity for further study.

    Measured: At baseline, day 1 of course 3, and end of treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Hsp90 inhibitor STA-9090, laboratory biomarker analysis and polymerase chain reaction in people with Adenocarcinoma of the Prostate and Hormone-resistant Prostate Cancer, run by Barbara Ann Karmanos Cancer Institute at 4 sites in United States.

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 19 inclusion and 13 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 18 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 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.

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 14 Apr 2015). 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?

PFS Proportion Achieved With STA-9090 in Men With CRPC Who Have Received Prior Docetaxel Based Therapy (time frame: At 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Sep 2018.
