Brief Summary:
This study will advance a novel and potent strategy to eliminate minimal residual disease (MRD) in triple negative breast cancer (TNBC) present even after multimodal treatment, thereby improving survival and increasing cure rate in this aggressive cancer. Patients with locally advanced TNBC are at high risk of developing lethal metastatic disease within 2 years of diagnosis, especially for those without a pathologic complete response (pCR) after neoadjuvant chemotherapy. The high risk occurs despite surgical excision of the primary tumor and axillary lymph nodes to eliminate residual disease.

Condition or disease Intervention/treatment Phase
Breast Metastatic Triple Negative Cancer Disseminated Tumor Cell Drug: Capecitabine Combination Product: Sarilumab 150mg or 200 mg plus Capecitabine Combination Product: Sarilumab 150mg plus Capecitabine Phase 1 Phase 2

Detailed Description:

The study will consist of two phases, I and II. Phase I will be made up of 2 patient cohorts, Cohorts A and B.

  • Cohort A, will include Stage I to III TNBC patients with less than a complete pCR after neoadjuvant therapy who will be treated with capecitabine (1000mg/m2/BID; for 14 days every 21 days) as standard of care. This cohort will be used to determine baseline bone marrow disseminated tumor cells (BM DTC) response to capecitabine alone.
  • Cohort B, will include patients with metastatic TNBC, HER2/neu-negative and hormone resistant breast cancer. A total of 4 doses of sarilumab will be given with the starting dose of 150 mg SQ at 3-weeks cycles given 3 days prior to each of the first 4 of 8 cycles of capecitabine (1000 mg/m2/BID; for 14 days every 21 days). If dose escalation is possible, sarilumab will be administered every 3 weeks at 200 mg SQ for 4 doses.

Phase II is a single arm study in Stage I to III TNBC with less than a complete pCR after neoadjuvant therapy evaluating the combination of sarilumab with capecitabine (1000mg/m2/BID; for 14 days every 21 days) as compared to historical control patients treated with capecitabine alone. There are 8 cycles of capecitabine. The first 4 cycles will be combined with sarilumab. The Phase II sarilumab dose will be determined by the Phase I best tolerated dose. In patients without bone marrow DTC clearance after 4 doses of sarilumab, 4 more doses of sarilumab will be given in combination with the last 4 cycles of capecitabine.

Primary Outcome Measures :
  1. Phase I: Maximum Tolerated Dose (MTD) [ Time Frame: first treatment up to 9 weeks ]
    Establish MTD of sarilumab plus capecitabine in patients with metastatic TNBC and metastatic HER2/neu-negative and hormone resistant breast cancer

  2. Phase I: Dose-limiting toxicity (DLT) [ Time Frame: first treatment up to 9 weeks ]
    Defined events that are possibly, probably, or definitely related to the study treatment:

  3. Phase II:To determine the percent of patients with positive DTC becoming negative DTCs after treatment [ Time Frame: baseline up to 14 weeks ]
    Bone marrow aspirates will be performed before treatment and at defined time points during treatment.

Criteria

Inclusion Criteria:

  • A. Written informed consent obtained from the subject and the ability for the subject to comply with all the study-related procedures.
  • B. Both males and females ≥ eighteen years of age
  • C. A clinical diagnosis of metastatic triple negative or hormone resistant, Her2/neu-negative breast cancer that has been confirmed histologically at one point during the course of the disease. TNBC is defined as ER/PR IHC positivity rate of <10% and Her2Neu-negative (Phase I Cohort B only)
  • D. A life expectancy of at least 6 months. (Phase I only)
  • E. Any previous cytotoxic chemotherapy must have been a minimum of 3 weeks prior to study drug administration. There is no limit on the number of prior therapies. For ER/PR-positive tumors, endocrine therapy must have been included in at least one of those prior regimens. Prior capecitabine is allowed only if not given in the treatment regimen immediately prior to the enrollment in this study. (Phase I Cohort B only)
