Brief summary

The purpose of this study is to find the highest dose of dasatinib that can be safely given to a patient when the drug is given in combination with the known anticancer drug paclitaxel. Paclitaxel is an established anti-cancer drug, used in the treatment of many cancers, and it is an approved treatment for breast cancer. Dasatinib has been approved by the Food and Drug Administration for use as a single therapy in another kind of cancer, but its use in breast cancer patients, and in combination with paclitaxel is investigational. In this study, we will test the safety of dasatinib when given at different dose levels in combination with paclitaxel. We want to find out what effects, good and/or bad, it has on the patient and on metastatic breast cancer.

Interventions

DRUGDasatinib and Paclitaxel

A treatment cycle will consist of 28 days, according to the following schedule: Dasatinib 120MG PO once daily, Weekly paclitaxel 80 mg/m2 given intravenously over 1 hour on day 1, 8, and 15 of a 28 day cycle. The trial will initially test the combination of weekly paclitaxel and dasatinib given PO, once daily , continuously. In case of 2 dose-limiting toxicities (DLT) in the first cohort (0), the next cohort will test dasatinib given with a different schedule, 5 days on and 2 days off, omitting dasatinib the day prior and the day of administration of paclitaxel.

Patients with any ER/PR disease status are eligible. * A paraffin-embedded tissue block or unstained slides from prior surgery must be available. * Evidence of recurrent or progressive locally advanced or metastatic breast cancer. Presence of: * For the phase I portion: at least one evaluable or measurable metastatic lesion , * For the phase II portion: at least one measurable metastatic lesion according to the RECIST criteria which has not been irradiated (i.e. newly arising lesions in previously irradiated areas are accepted).
