Genomic and Proteomic Profiling Targets Influenced Treatment in Metastatic Breast Cancer

A Two Arm Pilot Study Utilizing Molecular Profiling to Find Potential Targets and Influence Treatments for Patients With Metastatic Breast Cancer or Advanced Gynecological Malignancies

The primary objective is to examine the impact on progression-free survival of targeted therapy for breast cancer suggested by proteomic and genomic profiling.

To explore the impact of targeted therapy for breast cancer suggested by proteomic and genomic profiling using RPMA, targeted resequencing, IHC analysis, WGS, RNA-seq, and Exome sequencing on progression-free survival. When a molecular target cannot be identified, the patient will be treated with a therapy selected on an empirical basis by the investigator/treating physician at the individual site and will be followed for survival status. Only available, FDA-approved agents will be used.

Inclusion Criteria:

• Life expectancy of >3 months
• Diagnosis of metastatic breast cancer or an advanced gynecological malignancy with measurable disease
• Age greater than or equal to 18 years
• ECOG performance status of 0-1

Exclusion Criteria:

• Metastatic lesions that are not accessible to biopsy
• Symptomatic CNS metastasis
