Open-label Trial of GlivecWith Unresectable or Metastatic Malignant Gastrointestinal Stromal Tumors

This study has been completed.
Information provided by (Responsible Party):
Central European Cooperative Oncology Group Identifier:
First received: February 16, 2006
Last updated: August 11, 2015
Last verified: May 2012

The rationale is to assess the clinical and biological activity of Imatinib and to compare the data with historic data.

Additionally this study has been designed to gain more experience with the treatment of GIST in several Central and Eastern European Countries.

Primary Outcome Measures:
  • Time to Disease Progression [ Time Frame: until PD ]

Secondary Outcome Measures:
  • Time to Disease Progression [ Time Frame: until PD ]
  • Overall Survival [ Time Frame: until death ]

Enrollment: 125
Study Start Date: March 2004
Study Completion Date: July 2008
Primary Completion Date: July 2006 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Glivec
    400mg p.o./day in a population of patients with locally advanced (=not amenable to surgery with curative intent) or metastatic malignant GIST. Glivec® may be increased to 600 mg p.o./day and then 800 mg p.o./day (400 mg b.i.d.) if the patient is progressing
Detailed Description:

This is a multicenter open label clinical trial to be performed in patients with incurable malignant GISTs that are unresectable or metastatic. Approximately 150 patients will enter the trial.

Patients will receive Imatinib 400 mg p.o./day for a period of up to 24 months provided that in the opinion of the investigator the patient is benefiting from treatment with Imatinib, and in the absence of any safety concerns.

Treatment after completion of the 24 months study is at the discretion of the investigator. Imatinib should be increased to 600 mg p.o./day and then to 400 mg b.i.d if the patient is progressing on the respective dose level.

Inclusion Criteria:

  • Patients >= 18 years of age
  • Histologically documented diagnosis of GIST which is malignant as well as unresectable (=not amenable to surgery with curative intent) and/or metastatic and therefore incurable Immunohistochemical documentation of c-kit (CD117) expression by tumor

  • Performance status 0,1, 2 or 3 (ECOG)
  • Adequate end organ function, defined as the following: total bilirubin < 1.5 x ULN, SGOT and SGPT < 2.5 x UNL (or < 5 x ULN if hepatic metastases are present), creatinine < 1.5 x ULN, ANC > 1.5 x 109/L, platelets > 100 x 109/L
  • Female patients of child-bearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing. Post menopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential. Male and female patients of reproductive potential must agree to employ an effective barrier method of birth control throughout the study and for up to 3 months following discontinuation of study drug
  • Life expectancy of at least 6 months
  • Written, voluntary, informed consent
  • Patients who were previously treated with chemotherapy will be eligible for this study
  • Patient who are at least 5 years free of melanoma will be eligible for this study

Exclusion Criteria:

  • Patient has received any other investigational agents within 28 days of first day of study drug dosing
  • Patient is < 5 years free of another primary malignancy except: if the other primary malignancy is not currently clinically significant nor requiring active intervention and CECOGs' approval is obtained, or if other primary malignancy is a basal cell skin cancer or a cervical carcinoma in situ. Existence of any other malignant disease is not allowed
  • Patient with Grade III/IV cardiac problems as defined by the New York Heart Association Criteria. (i.e., congestive heart failure, myocardial infarction within 6 months of study)
  • Female patients who are pregnant or breast-feeding.
  • Patient has a severe and/or uncontrolled medical disease (i.e., uncontrolled diabetes, chronic renal disease, or active uncontrolled infection)
  • Patient has a known brain metastasis
  • Patient has an acute or known chronic liver disease (i.e., chronic active hepatitis, cirrhosis)
  • Patient has a known diagnosis of human immunodeficiency virus (HIV) infection

  • Patient previously received radiotherapy to >= 25 % of the bone marrow
  • Patient had a major surgery within 2 weeks prior to study entry
  • Patient with any significant history of non-compliance to medical regimens or with inability to grant reliable informed consent
  • Therapeutic anticoagulation with warfarin (e.g. Coumadin® or Coumadine®)
