Breast Cancer Clinical Trial
Panitumumab and Pembrolizumab in Combination With Neoadjuvant Chemotherapy for the Treatment of Stage III-IV Triple Negative Breast Cancer
Summary
This phase II trial tests whether panitumumab and pembrolizumab in combination with standard of care chemotherapy before surgery (neoadjuvant) works to shrink tumors in patients with stage III-IV triple negative breast cancer. Panitumumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as paclitaxel, carboplatin, doxorubicin, and cyclophosphamide work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving panitumumab and pembrolizumab in combination with neoadjuvant chemotherapy may kill more tumor cells in patients with triple negative breast cancer.
Full Description
PRIMARY OBJECTIVE:
I. To determine the pathological complete response (pCR rate) of the proposed combination in patients with newly diagnosed triple-negative inflammatory breast cancer (TN-IBC).
SECONDARY OBJECTIVES I. To evaluate the surgical complication rate after the completion of the proposed treatment.
II. To determine the change of EGR1 related to the efficacy of proposed treatment. (Key Secondary Objective) III. To determine the immunological change of tumor microenvironment (TME) related to the efficacy of proposed treatment. (Key Secondary Objective) IV. To define the cutoff or threshold of changes of EGR1, which will correlate with the pCR.
V. To define the cutoff or threshold of immunological changes of TME, which will correlate with the pCR.
VI. To determine two-year recurrence-free survival (RFS) rates. VII. To determine two-year overall survival (OS) rates. VIII. To determine the safety and tolerability. IX. To determine the predictive biomarkers to predict the therapeutic response. (correlative study)
OUTLINE:
CYCLES 1-4: Patients receive pembrolizumab intravenously (IV) over 30 minutes and panitumumab IV over 30-60 minutes on day 1 of cycle 0. Cycle 0 continues for 7 days in the absence of disease progression or unacceptable toxicity. Patients then receive panitumumab IV over 30-60 minutes on days 1, 8, and 15 of cycles 1-3 and days 1 and 8 of cycle 4, pembrolizumab IV over 30 minutes on day 1 of cycles 2-4, paclitaxel IV over 1-3 hours on days 1, 8, and 15 of cycles 1-4, and carboplatin IV over 30 minutes on day 1, 8 and 15 of cycles 1-4. Treatment repeats every 21 days for up to 4 cycles in the absence of disease progression or unacceptable toxicity.
CYCLES 5-8: Patients receive standard of care treatment, including pembrolizumab IV over 30 minutes, doxorubicin IV over 15 minutes and cyclophosphamide IV over 30 minutes on day 1 of each cycle. Treatment repeats every 21 days for up to 8 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 and 90 days, then every 6 months for 2 years from date of surgery.
Eligibility Criteria
Inclusion Criteria:

Cohort 1, de novo stage IV (safety run-in)
Cohort 2, stage III or de novo stage IV
Known estrogen receptor (ER), progesterone receptor (PR), and HER2 status defined as triple negative breast cancer (TNBC)
TNBC as defined as ER and PR =< 10% by immunohistochemistry, and HER2-negative (defined as IHC 0, 1+, or 2+ and FISH negative. The positivity of FISH is determined as per ASCO/CAP guideline).
Eastern Cooperative Oncology Group (ECOG) performance status of 0-1
Absolute neutrophil count (ANC) >= 1,500/mcL
Platelets >= 100,000/mcL
Hemoglobin (Hgb) >= 10g/dL
Creatinine levels < 1.5 x upper limit of normal (ULN)
Total bilirubin =< 1.5 x ULN
Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =< 2.5 x ULN or =< 5 x ULN for patients with liver metastases
Subjects of childbearing potential should be willing to use effective methods of birth control or be surgically sterile or abstain from heterosexual activity for the course of the study through at least 4 months after the last dose of study drug. Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year. Effective methods of birth control include 1) Use of hormonal birth control methods: pills, shots/injections, implants (placed under the skin by a health care provider), or patches (placed on the skin); 2) Intrauterine devices (IUDs); 3) Using 2 barrier methods (each partner must use 1 barrier method) with a spermicide. Males must use the male condom (latex or other synthetic material) with spermicide. Females must choose either a Diaphragm with spermicide, or Cervical cap with spermicide, or a sponge (spermicide is already in the contraceptive sponge)
Negative serum or urine pregnancy test for subjects of childbearing potential
Exclusion Criteria:
Any other previous or concurrent antitumor therapies for the current cancer diagnosis event
Known diagnosis of immunodeficiency, which defined as on chronic systemic steroid therapy or any other forms of immunosuppressive therapy in excess of the equivalent of prednisolone 10 mg once daily
History of malignancy (other than breast cancer) within 5 years, except basal cell carcinoma or squamous cell carcinoma of the skin, melanoma in-situ or in situ cervical cancer that has undergone potentially curative therapy
Known active central nervous system metastases and/or carcinomatous meningitis
Known significant cardiovascular disease, such as a history of myocardial infarction, acute coronary syndrome, congestive heart failure (CHF) New York Heart Association (NYHA) class II-IV, or history of CHF NYHA class III or IV
Ejection fraction < 50% by echocardiogram (ECHO) or multigated acquisition scan (MUGA)
Known active or uncontrolled autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids chronic corticosteroid use or immunosuppressive agents. Subjects with vitiligo or resolved childhood asthma/atopy would be an exception to this rule. Subjects that require intermittent use of bronchodilators or local steroid injections would not be excluded from the study. Subjects with hypothyroidism stable on hormone replacement or Sjogren's syndrome will not be excluded from the study
History of (non-infectious) pneumonitis that required steroids or has a current diagnosis of pneumonitis
