Brief Summary:
An open-label, non-comparative study conducted to investigate the activity and safety of imatinib mesylate in refractory desmoplastic small round cell tumors expressing PDGF-R. Patients will be treated up to 12 months, or to disease progression. Tumor will be evaluated according to Recist criteria

Condition or disease Intervention/treatment Phase
Refractory Desmoplastic Small Round Cell Tumors Drug: Imatinib mesilate Phase 1 Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 9 participants
Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Open-label Trial of Imatinib Mesylate in Patients With Refractory Desmoplastic Small Round Cell Tumors (DSRCT) Expressing PDGF-R
Study Start Date : August 2005
Actual Primary Completion Date : June 2009

Arm Intervention/treatment
Experimental: Gleevec/Glivec Drug: Imatinib mesilate
Other Name: STI571

Primary Outcome Measures :
  1. Overall tumor response rates [ Time Frame: Assessed every 3 months ]
    An imaging technique (CT scan or MRI) determined tumor response according to RECIST criteria.

Secondary Outcome Measures :
  1. Explore how Imatinib cooperated with other treatment modatilities [ Time Frame: Survival data was collected until death ]
    Recorded survival after treatment and other associated treatment modalities.

  2. Safety and tolerability [ Time Frame: Safety data collected until patients were no longer in study ]
  3. Conversion rate to surgical resectability [ Time Frame: After best tumor response. ]
    Assessed actual resectability rate after therapy compared to resectability before therapy.

  4. Mutational analysis of molecular targets of imatinib (at any time during the study) [ Time Frame: At any time during the study ]
