Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To estimate, by subgroup, objective response rate (ORR) of dasatinib in women with recurrent or progressive locally-advanced or metastatic breast cancer.;Secondary Objective: 1. To estimate, by subgroup, Disease Control Rate (DCR) and proportion free of progression at week 9, 17 and 25, Progression-Free Survival (PFS) distribution, and response duration 2. To determine the safety and tolerability of dasatinib in this population 3. To obtain pharmacokinetic (PK) and pharmacodynamic data 4. To obtain exploratory tumor biomarker and pharmacogenomic data;Primary end point(s): Efficacy: Anti-tumor efficacy will be assessed by radiographic or clinical measurement. Primary analysis will be radiographically-defined ORR by RECIST criteria. Disease control rate (DCR) will be the key secondary efficacy endpoint and basis for interim analysis. Safety/tolerability: Safety and tolerability is a main secondary endpoint. Adverse events will be assessed continuously and graded according to NCI Common Terminology Criteria for Adverse Events version 3.0 (CTCAEv3) for all treated subjects. | — |
