Phase II Trial Evaluating the Efficacy and Safety of Neoadjuvant Neratinib and Chemotherapy in Early Stage Triple-Negative Breast Cancer Patients Who Exhibit Enhanced HER2 Signaling by Live Cell HER2 Signaling Transduction Analysis (FACT-2)

An Open-Label Phase II Trial to Evaluate the Efficacy and Safety of Neoadjuvant Neratinib Followed by Weekly Paclitaxel and Carboplatin Plus Neratinib in Early Stage Triple-Negative Breast Cancer Patients Who Exhibit Enhanced HER2 Signaling by Live Cell HER2 Signaling Transduction Analysis (FACT-2)

Study Overview

• Status: Active, not recruiting
• Conditions: Triple Negative Breast Cancer; HER2-positive Breast Cancer; Early-stage Breast Cancer
• Intervention / Treatment: Drug: Neratinib

Detailed Description

This is a prospective, single arm, open label, interventional study designed to evaluate the efficacy of neoadjuvant chemotherapy with a pan-HER inhibitor in patients with ER-/PR-/HER2-(triple-negative) invasive breast cancer who have abnormal HER2-driven signaling activity determined by the Celcuity CELx HER2 signal function (HSF) test. Patients will be required to have a prescreening research core needle biopsy to procure a fresh tumor specimen that will be sent to Celcuity for CELx HSF testing, in order to assess the status of their HER2-driven signaling activity (abnormally or normally active). While waiting for results of the CELx HSF test, patients may receive the first dose of weekly paclitaxel at the investigator's discretion. Patients whose CELx HSF test indicate they have abnormal HER2-driven signaling activity will then receive neratinib as a single agent daily for 21 days and then neratinib plus paclitaxel and carboplatin.

The primary endpoint of the study is to evaluate whether patients with triple-negative breast cancers (estrogen (ER) and progesterone (PR) receptors < 10%; HER2-negative per standard ASCO/CAP testing criteria), but with abnormal HER2-driven signaling pathways determined by the Celcuity CELx HSF assay, and who receive HER2-targeted therapy with neoadjuvant chemotherapy will have a higher rate of pathological complete response (pCR) in the breast and lymph nodes (pCR breast and lymph nodes) than has been found historically in patients with triple-negative breast cancer who have received neoadjuvant chemotherapy. Secondary endpoints include pathologic complete response (breast), clinical complete response (cCR), residual cancer burden (RCB) 0-1 index, and relationship between quantitative CELx score and pCR rate.

It is expected that approximately 135 patients will need to be prescreened in order to enroll 27 patients who have abnormal HER2-driven signaling activity.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years and older (Adult, Older Adult)
• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

• The patient must have consented to participate and must have signed and dated an appropriate IRB-approved consent form that conforms to federal and i institutional guidelines for the pre-entry research core biopsy for CELx HSF testing and for initiating chemotherapy
• Patients must be female.
• Patients must be ≥ 18 years old.
• Patient must have an ECOG performance status of 0 or 1
• The diagnosis of invasive adenocarcinoma of the breast must have been made by core needle biopsy.
• The primary breast tumor must be palpable and measure ≥ 1.0 cm on physical exam.
• The regional lymph nodes can be cN0 or cN1
• The tumor size can be T1c or T2

• Ipsilateral axillary lymph nodes must be evaluated by imaging (mammogram, ultrasound, and/or MRI) within 6 weeks prior to initiating chemotherapy. If suspicious or abnormal, FNA or core biopsy is recommended, also within 6 weeks prior to initiating chemotherapy. Findings of these evaluations will be used to determine the nodal status prior to initiating chemotherapy.

  • Nodal status - negative

    • Imaging of the axilla is negative;
    • Imaging is suspicious or abnormal but the FNA or core biopsy of the questionable node(s) on imaging is negative;

  • Nodal status - positive

    • FNA or core biopsy of the node(s) is cytologically or histologically suspicious or positive.
    • Imaging is suspicious or abnormal but FNA or core biopsy was not performed.
• Tumor specimen obtained at the time of diagnosis must have estrogen (ER) and progesterone (PR) receptors < 10%.

• Tumor specimen obtained at the time of diagnosis must have been determined to be HER2-negative as follows:

  • Immunohistochemistry (IHC) 0-1+; or
  • IHC 2+ and ISH non-amplified with a ratio of HER2 to CEP17 < 2.0, and if reported, average HER2 gene copy number < 4 signals/cells; or
  • ISH non-amplified with a ratio of HER2 to CEP17 < 2.0, and if reported, average HER2 gene copy number < 4 signals/cells.

• Blood counts performed within 6 weeks prior to initiating chemotherapy must meet the following criteria:

  • Absolute neutrophil count (ANC) must be ≥ 1200/mm3;
  • platelet count must be ≥ 100,000/mm3; and
  • hemoglobin must be ≥ 10 g/dL.

• The following criteria for evidence of adequate hepatic function performed within 6 weeks prior to initiating chemotherapy must be met:

  • total bilirubin must be ≤ upper limit of normal (ULN) for the lab unless the patient has a bilirubin elevation > ULN to 1.5 x ULN due to Gilbert's disease or similar syndrome involving slow conjugation of bilirubin; and
  • alkaline phosphatase must be ≤ 2.5 x ULN for the lab; and
  • AST must be ≤ 1.5 x ULN for the lab.
  • Alkaline phosphatase and AST may not both be > the ULN. For example, if the alkaline phosphatase is > the ULN but ≤ 2.5 x ULN, the AST must be ≤ the ULN. If the AST is > the ULN but ≤ 1.5 x ULN, the alkaline phosphatase must be ≤ ULN. Note: If ALT is performed instead of AST (per institution's standard practice), the ALT value must be ≤ 1.5 x ULN; if both were performed, the AST must be ≤ 1.5 x ULN.
• Patients with AST or alkaline phosphatase > ULN are eligible for inclusion in the study if liver imaging (CT, MRI, PET-CT, or PET scan) performed within 6 weeks prior to initiating chemotherapy does not demonstrate metastatic disease and the requirements in criterion 4.2.13 are met.
• Patients with alkaline phosphatase that is > ULN but ≤ 2.5 x ULN or unexplained bone pain are eligible for inclusion in the study if a bone scan, PET-CT scan, or PET scan performed within 6 weeks prior to initiating chemotherapy does not demonstrate metastatic disease.
• Serum creatinine performed within 6 weeks prior to initiating chemotherapy must be ≤ 1.5 x ULN for the lab.
• The left ventricular ejection fraction (LVEF) assessment by echocardiogram or MUGA scan performed within 90 days prior to initiating chemotherapy must be ≥ 50% regardless of the facility's lower limit of normal (LLN).
• Patients with reproductive potential must agree to use an effective non-hormonal method of contraception during therapy, and for at least 7 months after the last dose of study therapy.
• Patients are candidates for weekly paclitaxel and carboplatin chemotherapy as determined by treating physician.
• Patients with multifocal breast cancer are included as long as none of the tumors are HER2 positive by IHC or FISH and targeted lesion meets current inclusion criteria.
• Conditions for patient eligibility (Study Enrollment) A patient cannot be considered eligible for this study unless all of the following conditions are met:
• The patient must have consented to participate and must have signed and dated an appropriate IRB-approved consent form that conforms to federal and institutional guidelines for the FACT-2 study treatment.
