Outcomes
Primary Outcomes
Number of Participants With Objective Response
Time Frame: From day of first treatment through Week 25 or at time of discontinuation from study treatment.
Tumor response was assessed according RECIST criteria: PR=at least 30% reduction in the sum of the LD of all target lesions in reference to the baseline sum LD, CR=Disappearance of all non-target lesions. Objective tumor response was defined as a PR or CR.
Percentage of Participants With Objective Response
Time Frame: From day of first treatment through Week 25 or at time of discontinuation from study treatment
Tumor response was assessed according RECIST criteria: PR=at least 30% reduction in the sum of the LD of all target lesions in reference to the baseline sum LD, CR=Disappearance of all non-target lesions. Percentage of participants with objective tumor response was determined by the number of participants with PR or CR divided by the total number of response-evaluable participants.
Best Overall Response
Time Frame: From day of first treatment through Week 25 or at time of discontinuation from study treatment
Response assessed using Response Evaluation Criteria In Solid Tumors (RECIST) criteria: Complete Response (CR)=disappearance of all target and non-target lesions; Partial Response (PR)=≥30% decrease in sum of longest diameter (LD) of target lesions; SD=small changes not meeting above criteria; Progressive Disease (PD)=appearance of new lesion(s), ≥ 20% increase in the sum of the LD of target lesions, or progression of existing non-target lesions; Clinical Progression (cPD)=deterioration related to disease requiring treatment without radiographic PD.
Secondary Outcomes
- Number of Response-evaluable Participants With Disease Control (DCR)(From day of first treatment through Week 25 or at time of discontinuation from study treatment.)
- Percentage of Response-evaluable Participants With Disease Control (DCR)(From day of first treatment through Week 25 or at time of discontinuation from study treatment.)
- Number of Participants Who Progressed(From Baseline (Week 0) to time of PD or discontinuation of last participant from study treatment (Week 45))
- Median Progression Free Survival (PFS)(From Baseline (Week 0) to time of PD or discontinuation of last participant from study treatment (Week 45))
- Percentage of Participants With Progression-free Survival (PFS) at Weeks 9, 17, and 25(At Weeks 9, 17, and 25)
- Duration Of Objective Response(the time (in weeks) between the first date that criteria for PR were met and the first date that PD or cPD was observed)
- Number of Participants With Death, Adverse Events (AEs), and AEs Leading to Discontinuation(Continuous assessment beginning at initiation of study drug until 30 days after the last dose of study drug)
- Number of Participants With On-study CTCAE Version 3.0 Grade 3-4 Laboratory Abnormalities(Continuous assessment beginning at initiation of study drug until 30 days after the last dose of study drug)
- Number of Participants With Serious AEs (SAEs), Drug-related AEs, Drug-related SAEs, and Drug-Related Grade 3 AEs(Continuous assessment beginning at initiation of study drug until 30 days after the last dose of study drug)
- Number Of Participants With Notable Drug-related AEs(Continuous assessment beginning at initiation of study drug until 30 days after the last dose of study drug)
- Pharmacokinetics (PK): Plasma Concentration of Dasatinib at Week 3(PK assessment was performed at Week 3 visit (Day 15 ±4 days). Blood samples were obtained at Time = 0 hours, and at 1, 3 and 6 hours after each dose, and a trough sample was obtained immediately prior to any dose (~12 hours).)
- PK: Plasma Concentration of Dasatinib at Week 7 or Week 9(PK assessment was performed at Week 7 or 9 visit. Blood samples were obtained at Time = 0 hours, and at 1, 3 and 6 hours after each dose, and a trough sample was obtained immediately prior to any dose (~12 hours).)
- Pharmacodynamics: Percent Change From Baseline In Plasma Level of Collagen Type IV at Week 3 in Participants With and Without DCR(At Baseline and Week 3 of treatment (Day 15 ±4 days))
- Pharmacodynamics: Percent Change From Baseline In Plasma Level of Collagen Type IV at Week 5 in Participants With and Without DCR(Week 5)
- Pharmacodynamics: Percent Change From Baseline In Plasma Level of VEGFR2 at Week 3 in Participants With and Without DCR(At Baseline and Week 3 of treatment (Day 15 ±4 days))
- Pharmacodynamics: Percent Change From Baseline In Plasma Level of VEGFR2 at Week 5 in Participants With and Without DCR(At Baseline and Week 5 of treatment)
