Brief Summary:
The purpose of this study is to learn why certain drugs stop working in patients.In lab studies, tumors become resistant in several ways. Specific molecules seem to change and this may be why therapy stops working. However, we do not know if the same molecules change in patients. This study is being done to see if they do change. If we learn more about how patients become resistant, we may be able to offer better treatment in the future.

Outcome Measures

Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. To look for mutations in druggable oncogenic pathways in tumors progressing on anti-HER2 therapy or hormonal therapy [ Time Frame: 3 years ]
  2. To characterize the activity of the PI3K signaling pathway in progressive breast tumors using proteomic methods [ Time Frame: 3 years ]
  3. To develop new laboratory models of treatment refractory breast cancer from human tumor specimens [ Time Frame: 3 years ]

Secondary Outcome Measures :
  1. To look for mutations in druggable oncogenic pathways in tumor progressing on breast cancer targeted therapies [ Time Frame: 3 years ]
  2. To evaluate dynamic proteomic changes in response to inhibition of the RTK/PI3K/ATK/mTOR pathway. [ Time Frame: 3 years ]
  3. To characterize the genetic heterogeneity of progressive, metastatic tumors using next generation sequencing [ Time Frame: 3 years ]

Criteria

Inclusion Criteria:

All patients:

  • Diagnosed with breast cancer.
  • Patient must be able to consent to a biopsy
  • Patient must be able to safely undergo a secondary biopsy, if needed.

Cohort 1

  • Patients who previously received treatment with anti-HER2 therapy (including trastuzumab, pertuzumab, TDM1, lapatinib, neratibin, or DS8201) as part of adjuvant chemotherapy and now have progressive or recurrent breast cancer or, patients who previously (or currently) received anti-HER2 therapy as part of a regimen for metastatic breast cancer and subsequently experienced.
  • Evidence of disease progression or recurrence after prior therapy (e.g. radiologic progression by RECIST criteria or new metastasis).
  • Prior tumor biopsy (may be original) defined as HER2+ by amplification by FISH (>1.9 gene copy number) or IHC 3+.

Cohort 2

  • Patients who previously received treatment with hormonal therapy (including aromatase inhibitors or SERMs or SERDs) as a part of adjuvant therapy and now have progressive or recurrent breast cancer or patients who previously (or currently) receive hormonal therapy as part of a regimen for metastatic breast cancer and subsequently experienced evidence of disease progression.

Cohort 3

  • Patients not eligible for Cohorts 1 or 2.

Exclusion Criteria:

  • Patients who are unable to consent to a biopsy.
  • Patients for whom a repeat biopsy would be medically unsafe
