Last updated: June 30, 2011
Last verified: June 2011
Open-label, multicenter study of imatinib (400mg/die p.o.)in patients with advanced gastrointestinal stromal tumors. Patients will be treated for up to 12 months. Data regarding its best clinical use in terms of tumor response, survival, tolerability and safety profile will be prospectively collected.

Drug: Imatinib
Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

Primary Outcome Measures:
  • tumor response /RecIST criteria) [ Time Frame: first 2 months monthly, then every 3 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • SAE and tolerability profile [ Time Frame: ongoing basis ] [ Designated as safety issue: Yes ]
  • OS, DFS [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • effects of the therapy when combined with other treatment modalities i.e. surgery of residual disease. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • which early predictive factors of tumor response may be of relevance, i.e. conventional pathologic characteristics of tumor and radiological aspects. [ Time Frame: 12 months ] [ Designated as safety issue: No ]

Enrollment: 135
Study Start Date: March 2002

Arms Assigned Interventions
Experimental: Imatinib Drug: Imatinib


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients ≥ 18 years of age.
  2. Histologically documented diagnosis of GIST, unresectable and/or metastatic and therefore incurable with any conventional multimodality approach.
  3. Immunohistochemical documentation of c-kit (CD117) expression by tumor, as detected on a tumor sample taken within 6 weeks of study entry.
  4. At least one measurable site of disease (RECIST Criteria), or other response assessment criteria, as appropriate.
  5. Performance status 0,1, 2 or 3 (ECOG).
  6. Adequate end organ function.
  7. Adequate bone marrow function.
  8. Female patients of child-bearing potential must have negative pregnancy test within 7 days before initiation of study drug dosing.

Exclusion Criteria:

  1. Previous treatment with any other investigational agents within 28 days of first day of study drug dosing, unless the disease is rapidly progressing.
  2. Other primary malignancy with < 5 years clinically assessed disease free interval, except basal cell skin cancer, cervical carcinoma in situ, or other neoplasms judged after consultation with the Steering committee to entail a low risk of relapse.
  3. Grade III/IV cardiac problems as defined by the New York Heart Association Criteria.
  4. Pregnancy, breast-feeding.
  5. Severe and/or uncontrolled medical disease.
  6. Known brain metastasis.
  7. Known chronic liver disease (i.e., chronic active hepatitis, and cirrhosis).
  8. Known diagnosis of human immunodeficiency virus (HIV) infection.
  9. Previous treatment with chemotherapy within 4 weeks (6 weeks for nitrosoureas or Mitomycin-C).
  10. Previous radiotherapy to ≥ 25 % of the bone marrow.
  11. Major surgery within 2 weeks prior to study entry.
