Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).

    The EU Clinical Trials Register currently displays   43974   clinical trials with a EudraCT protocol, of which   7312   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    gastrointestinal stromal tumor (GIST)
    E.1.1.1Medical condition in easily understood language
    Gastrointestinal stromal tumor (GIST) is a rare cancer affecting the digestive tract or nearby structures within the abdomen.
    E.1.1.2Therapeutic area Diseases [C] - Cancer [C04]
    MedDRA Classification
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    Calculate the recurrence-free survival (RFS) after randomisation
    E.2.2Secondary objectives of the trial
    1. Calculate the overall survival
    2. Calculate the GIST-specific survival
    3. Assess the toxicity in patients treated with imatinib
    4. Assess the Quality of life in patients treated with imatinib
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    1. Age ≥ 18 years.
    2. Morphological and immunohistological documentation of GIST (immunostaining for KIT [CD117] and/or DOG-1 positive, or mutation of KIT or PDGFRA present in tumour tissue).
    3. Macroscopically complete surgical resection of GIST (either R0 or R1 resection).
    4. Mutation analysis of KIT and PDGFR genes has been carried out.
    5. A high risk of tumour recurrence following surgery and 3 years of adjuvant imatinib defined as one of the following:
    1) gastric GIST with mitotic count >10/50 HPFs HPF, high Power field of the microscope) or >10/5mm2, or
    2) non-gastric GIST with mitotic count >5/50 HPFs or >5/5 HPFs mm2, or
    3) non-gastric GIST treated with neoadjuvant imatinib and initially larger than 10 cm, or
    4) tumour rupture
    Tumour rupture may have occurred before or at surgery. Tumour rupture is defined by spillage of the tumour contents into the abdominal cavity. A core needle biopsy from the tumour, or tumour bleed with no apparent spillage of the tumour contents, are not considered ruptures.

    If only a small amount of pretreatment tumour tissue is available from a core needle biopsy, it is acceptable to multiply the mitotic count obtained from fewer than 50 HPFs to approximate the counts obtained from 50 HPFs in surgical biopsies, or to multiply the count obtained from a tumour tissue area less than 5 mm2 to approximate the counts obtained from the 5 mm2 area. However, if only minimal amount of tumour tissue is available from a core needle biopsy (from 5 or fewer HPFs, or only 1 mitosis can be identified), multiplication should not be attempted and is not considered acceptable. For further explanation of this expanded high risk classification, please see section 3.2.3.
    6. ECOG performance status ≤ 2.
    7. Adequate organ function, defined as
    serum total bilirubin <1.5 x ULN (upper limit of normal), serum AST (SGOT) and ALT (SGPT) <2.5 x ULN, creatinine <1.5 x ULN; blood ANC (neutrophil count) ≥1.0 x 109/L, platelet count ≥100 x 109/L.
    8. Female patients of childbearing potential must have a negative pregnancy test within 14 days before initiation of study drug dosing. Postmenopausal women must have amenorrhoea 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.
    9. Patient willing to be followed up at the study site regardless of the result of randomisation.
    10. Patient has provided a written, voluntary informed consent prior to study-specific screening procedures.
    E.4Principal exclusion criteria
    1. Presence of distant metastases or local recurrence of GIST.
    2. Not willing to donate tumour tissue and/or blood samples for the study molecular studies.
    3. Presence of a substitution mutation at PDGFRA codon D842 (usually D842V).
    4. Administration of adjuvant imatinib longer than for 3 years is planned regardless of the result of randomisation, or “life long” imatinib administration is planned.
    5. Prior adjuvant (+ neoadjuvant) therapy with imatinib mesylate for at least 35 months has not been completed, or the total duration of prior adjuvant (+ neoadjuvant) imatinib administration exceeds the total duration of 38 months.
    6. Neoadjuvant imatinib for a duration that exceeds 12 months.
    7. Longer than 4-week break during adjuvant imatinib administration.
    8. The dose of imatinib at completion of 3 years of adjuvant imatinib was 200 mg per day or less or greater than 800 mg per day.
    9. Patient has received any investigational anti-cancer agents during adjuvant imatinib or between completion of adjuvant imatinib and the date of randomisation.
    10. Patient has been free of another malignancy for less than 5 years
    except if the other malignancy is not currently clinically significant nor
    requiring active intervention, or if the other malignancy is one of the following: basal cell skin cancer, a cervical carcinoma in situ, a small (2 cm or less in diameter) node-negative breast cancer (pT1N0M0), a low Gleason score (<8) local (T1 or T2) prostate cancer. Recent existence of any other malignant disease is not allowed.
    11. Patient with Grade III/IV cardiac disease as defined by the New York Heart Association Criteria (i.e., congestive heart failure, myocardial infarction within 6 months of study entry).
    12. Female patients who are pregnant or breast-feeding.
    13. Severe and/or uncontrolled medical disease (i.e., uncontrolled diabetes, severe chronic renal disease, or active uncontrolled infection).
