Homologous Recombination Repair Status as a Biomarker of Response in Locally Recurrent/Metastatic Triple Negative Breast Cancer Patients Treated With Concurrent Cisplatin and Radiation Therapy

Running, not enrolling · Phase 2

Conditions studied: Locally Recurrent/Metastatic Triple Negative Breast Cancer

In brief

The study is being done to find out if the results of a pre-treatment biopsy can predict response to cisplatin and radiation treatment for patients with metastatic or recurrent triple negative breast cancer.

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Histologically-confirmed invasive triple negative breast cancer (ER <1%, PR <1%, her-2-neu 0-1+ by IHC or FISH-negative) or as determined by MD discretion
• Radiation to the recurrent or metastatic site is clinically indicated and would be considered standard care for palliation or for locoregional control
• Age ≥18 years
• Tumor to be irradiated is measurable by RECIST 1.1 or PRC
• Willingness to undergo tumor biopsy prior to initiation of treatment
• Life expectancy greater than 6 months
• ECOG performance status 0-2
• Any prior chemotherapy is allowed including prior treatment with platinum-containing chemotherapy
• Prior treatment with FDA-approved or investigational biologics or novel molecularly target therapies, including oral or IV formulations, are permitted.
• Patients must be off prior targeted therapy for at least 14 days prior to study biopsy.
• Use of an effective means of contraception in women of child-bearing potential
• Ability to comprehend and sign informed consent
• Adequate organ and marrow function within 14 days prior to study entry, defined as:
• Absolute neutrophil count (ANC)>1000/mm3
• Hemoglobin >9 gm/dl
• Platelets >100,000/mm3
• Serum creatinine <1.5 mg/dl OR creatinine clearance of ≥ 50 cc/min
• SGOT/SGPT<2.5X institutional ULN (<5X ULN if known liver metastases)

You may not qualify if…

• Unmeasurable target tumor site by RECIST 1.1 or PRC (ex: lesions <2 cm on CT or MR scan, leptomeningeal disease, ascites, pleural/pericardial effusion, lymphangitis, non-FDG-avid skin lesions)
• Brain metastases requiring focal or whole brain radiation will be excluded, as these lesions cannot be biopsied and can have life expectancies <6 months.
• Inability to obtain a biopsy of the tumor as deemed by the study Interventional Radiologist
• Prior chemotherapy completed <7 days prior to planned study entry
• Prior RT is allowed and must have been completed more than 7 days before planned study entry.
• Note: For re-irradiation cases, standard departmental guidelines should be followed so as to not exceed normal tissue
• Life expectancy less than 6 months
• Intercurrent illness or other major medical condition or comorbid condition that might affect study participation (uncontrolled renal, pulmonary or hepatic dysfunction or infection)
• Renal dysfunction for which cisplatin dose would be considered unsafe.
• Women on study must be neither pregnant nor nursing nor expected to become pregnant during therapy. For premenopausal women, negative pregnancy test within 14 days of RT is required.
• Concurrent active malignancy other than non-melanomatous skin cancer or carcinoma in-situ of the cervix, unless treatment for the previous cancer was completed >2 years prior to study entry and patient has remained disease-free.
