About this study

Official title: A Phase II Study of Pazopanib in Patients With Imatinib Refractory or Intolerant Gastrointestinal Stromal Tumors (GIST)

This study is being done to gather information about the safety (any harmful effects) and effectiveness (usefulness) of Pazopanib in the treatment of Gastrointestinal Stroma Tumors (GIST) that cannot be treated by surgery or has spread to other organs. The Food and Drug Administration (FDA) have approved Pazopanib for the treatment of advanced kidney cancer but it is not approved for the treatment of GIST. The investigators hope to learn about the safety and usefulness (effectiveness) of Pazopanib for patients with GIST.

What is being measured

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

  1. Non-progression Rate Based on RECIST 1.0 Criteria (CR+PR+SD)

    4-mo non-progression rate

    "Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions; Progression, as a 20% increase in the sum of the longest diameter of target lesions, or a measurable increase in a non-target lesion, or the appearance of new lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for disease progression

    Measured: 24 weeks

Secondary outcomes (1)

  1. Response Per Choi Criteria

    Response per Choi criteria

    • Complete response - Disappearance of all lesions; no new lesion
    • Partial response - A decrease in size of > or = 10% or a decrease in tumor density (HU) > or = 15% on CT. No new lesions. No obvious progression of nonmeasurable disease.
    • Stable disease - Does not meet the criteria for CR, PR, or PD. No symptomatic deterioration attributed to tumor progression.
    • Progressive disease - An increase in tumor size of > or = 10% and does not meet criteria of PR by tumor density (HU) on CT. New lesions. New intratumoral nodules or increase in the size of the existing intratumoral nodules.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Pazopanib in people with Gastrointestinal Stromal Tumor (GIST), run by Kristen Ganjoo at 2 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 18 inclusion and 21 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: stopped early, as of the sponsor's last update on 7 Apr 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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 7 Apr 2017). 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?

Non-progression Rate Based on RECIST 1.0 Criteria (CR+PR+SD) (time frame: 24 weeks). 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 NCT01391611.

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 7 Apr 2017.
