Comparison of Two Different Doses of STI571 in Treating Patients With Metastatic or Unresectable Gastrointestinal Stromal Tumor

Stopped early · Phase 3

Conditions studied: Gastrointestinal Stromal Tumor

In brief

Randomized phase III trial to compare the effectiveness of two different doses of STI571 in treating patients who have metastatic or unresectable gastrointestinal stromal tumor. STI571 may interfere with the growth of tumor cells and may be an effective treatment for cancer. It is not yet known which dose of STI571 is more effective in treating gastrointestinal stromal tumors.

You may qualify if…

• Patient must have a biopsy proven diagnosis of gastrointestinal stromal tumor (GIST) which is distantly metastatic or unresectable; tumors must meet BOTH of the following criteria:
• The primary must be of visceral or intra-abdominal origin
• All patients must have immunohistochemical documentation of KIT (CD117) expression by tumor documented by DAKO antibody staining for suggested methodology) Material must be submitted to the CALGB Pathology Coordinating Center for pathology review; it is strongly recommended that snap-frozen tissue biopsy and sera be stored for future submission whenever possible
• Patient must have measurable or non-measurable disease by conventional scan imaging (CT or MRI) or physical examination; tests used to assess disease must have been performed within 28 days prior to registration; if a target lesion has been previously embolized or irradiated, there must be objective evidence of progression to be considered for response assessment
• Patient must have an identified team (including a medical oncologist and a surgeon) to provide care
• Patient must not have known brain metastasis
• Patient must have a Zubrod performance status of 0 - 3
• Patient must have resolution of transient toxicities from any prior therapy to =< grade 1 (NCI-CTC version 2.0)
• The patient must not have received chemotherapy, biologic therapy or any other investigational drug for any reason within 28 days prior to registration; patients must not have had a major surgery within 14 days prior to registration
• If day 14 or 28 falls on a weekend or holiday, the limit may be extended to the next working day
• In calculating days of tests and measurements, the day a test or measurement is done is considered day 0; therefore, if a test is done on a Monday, the Monday two weeks later would be considered day 14; this allows for efficient patient scheduling without exceeding the guidelines
• No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease-free for 5 years
• All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines
• At the time of patient registration, the treating institution's name and ID number must be provided to the Data Operations Center in Seattle in order to ensure that the current (within 365 days) date of institutional review board approval for this study has been entered into the data base
• Patients on lower dose arm (Arm 1) will be allowed to increase the daily dose of STI-571 in the case of disease progression; if there is questionable disease progression, the treating investigator should contact the primary Study Coordinator, Dr. George Demetri at 617/632-3985 to review progression information and discuss treatment options
