Condition metastatic breast cancer
Treatments sorafenib, letrozole

Sponsor Rutgers, The State University of New Jersey
Collaborator Rutgers Cancer Institute of New Jersey
Start date August 2008
End date May 2017
Trial size 54 participants
Trial identifier NCT00634634, 0220070284, 040706, NCI-2012-00525, NJ 1107


Letrozole is an aromatase inhibitor that is approved in the first-line treatment of postmenopausal women with hormone receptor-positive or hormone receptor unknown locally advanced or metastatic breast cancer. Sorafenib may stop the growth of tumor cells by blocking blood flow to the tumor and by blocking some of the enzymes needed for cell growth. This phase I/II trial is studying the side effects and best dose of sorafenib when given in combination with letrozole and to see how well they work in treating postmenopausal women with metastatic breast cancer.

Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
sorafenib Nexavar
sorafenib dose will be given at a daily dose to be determined based upon the phase of study that patient is enrolled The phase II dose of sorafenib will be determined from the phase I portion of the study.
letrozole Femara
Patients will take letrozole orally at a daily dose of 2.5 mg/day on Days 1 through 28
