Participant Flow

50 patients with GIST were enrolled between June 2008 and December 2009 and 48 were evaluable for response. Between May 2007 and May 2009, 200 patients with advanced, high-grade sarcoma were enrolled into the aggressive subtype for this study. 116 patients were registered beginning in July 2007 to the indolent subtype for this study.

PRIMARY outcome

Timeframe: Up to 24 months

Population: 116 subjects enrolled in the Indolent subtype, however 109 subjects began treatment. 50 patients enrolled in the GIST subtype, however 48 patients were evaluable. This explains the discrepancy between Overall Number of Participants Analyzed.

Assessment of objective tumor response for response rate with MRI or CT using Choi criteria: Complete Remission (CR) Complete disappearance of all measurable and evaluable disease for at least 4 weeks; Partial Remission (PR) A 10% or greater decrease from the baseline in the sum of the largest diameters of all measurable target lesions.

PRIMARY outcome

Timeframe: At 6 months

Estimate the 6 month progression-free survival rate of "indolent" sarcomas treated with dasatinib. Progression is defined using Choi criteria, as a 10% or greater increase in the sum of all measurable target lesions over the smallest sum observed (over baseline if no decrease) using the same techniques as baseline, or clear worsening of any evaluable disease, or unequivocal reappearance of any lesion which had disappeared, or appearance of any new lesions of greater than double slice thickness in size, or any new or enlarging solid nodule in a previously hypodense treated mass.
