Inclusion criteria

  1. Histologically confirmed diagnosis of GIST which is unresectable and/or metastatic and either:

    • have not received any prior anti-neoplastic therapy other than adjuvant imatinib. Note: newly diagnosed patients may have received up to 14 days of treatment with imatinib for disease management while awaiting entry to the study or
    • recurrent GIST after stopping adjuvant treatment with imatinib and no subsequent treatment with any other therapies.
  2. At least one measurable site of disease on CT/MRI scan
  3. Performance status ≤ 2 (capable of self-care but unable to carry out any work)
  4. Normal organ, electrolyte and marrow function

Exclusion criteria

Exclusion Criteria:

  1. Any prior anti-neoplastic therapy with the exception of patients who have received adjuvant imatinib or patients with newly diagnosed metastatic/ unresectable GIST whose disease requires therapy while awaiting entry to the study.
  2. Disease progression during adjuvant therapy with imatinib
  3. History of active malignancy (other than GIST) within 10 years prior to study entry with the exception of previous or concomitant basal cell skin cancer, previous cervical carcinoma in situ.
  4. Impaired cardiac function

Other protocol-defined inclusion/exclusion criteria may apply

What researchers measure

Primary outcomes

  1. Time to Progression Free Survival (PFS)

    PFS was defined as the time from the date of start of treatment to the date of the first documented progression or death due to any cause. Progression is defined 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

    Time frame: up to month 37

The record gives a start of Mar 2009, a primary completion of Oct 2014 and a completion of Oct 2014. It does not say whether these dates are actual or estimated.

Results were first posted in Apr 2016, 1 year 6 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 16, 2016, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
