Sacituzumab Govitecan In TNBC

Summary

This research study is studying to evaluate sacituzumab govitecan for individuals with localized triple negative breast cancer (TNBC) The names of the study drugs involved in this study is: * Sacituzumab govitecan (SG) * Pembrolizumab (combination therapy with SG)

Eligibility

Inclusion Criteria:

* Female or male patients ≥ 18 years of age.
* Histologically confirmed diagnosis of invasive breast cancer, previously untreated.
* Participants must have biopsy proven ER negative (ER-), PR negative (PR-), HER2 negative (HER2-), invasive breast cancer. ER, PR, and HER2 positivity would be determined per ASCO/CAP guidelines by institutional (local) assessment. Patients with multi-focal and multicentric disease are eligible provided all histologically examined lesions are ER-/PR-/HER2- (local assessment). The need to biopsy additional lesions is at the discretion of the treating physician. Patients with bilateral invasive breast cancer are eligible provided all histologically examined lesions are ER-/PR-/HER2- (local assessment).
* Primary tumor (at least one lesion) 1 cm or greater measured by radiological imaging. Regional lymph node AJCC (v7) TNM stages N0-N2. If node positive, any primary tumor size is permissible. Absence of distant metastatic disease (AJCC TNM stage M0). Staging scans are not required and are per discretion of the treating physician.
* Pre- and postmenopausal women are eligible.
* ECOG performance status = 0, 1 (Karnofsky ≥60%, see Appendix A)
* Ability to understand and the willingness to sign a written informed consent form (ICF). Patient has signed the ICF prior to any screening procedures being performed and is able to comply with protocol requirements, including research biopsy.
* Patient has adequate bone marrow and organ function as defined by the following laboratory values at screening:
* Absolute neutrophil count (ANC) ≥ 1,500 per mm3
* Platelets ≥ 100,000 per mm3
* Hemoglobin ≥9.0 g/dL
* INR ≤1.5
* Serum creatinine \<1.5 mg/dL or creatinine clearance ≥50 mL/min
* Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \<2.5 x ULN.
* Total bilirubin ≤1.5 x ULN or in patients with well-documented Gilbert's Syndrome direct bilirubin ≤1.5 x ULN.

Exclusion Criteria:

* Inflammatory breast cancer, or locally recurrent breast cancer
* Participants currently receiving systemic therapy for any other malignancy or having received systemic therapy for a malignancy in the preceding 3 years.
* Uncontrolled inter-current illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia,or psychiatric illness/social situations that would limit compliance with study requirements.
* Clinically significant, uncontrolled heart disease and/or cardiac reppolarization abnormality including any of the following:

  * History of angina pectoris, symptomatic pericarditis, coronary artery bypass graft (CABG) or myocardial infarction within 6 months prior to study entry.
  * History of cardiac failure, known cardiomyopathy (LVEF \< 50%; new LVEF assessment is not specifically required for this trial), significant/symptomatic bradycardia, Long QT syndrome, family history of idiopathic sudden death or congenital long QT syndrome or any of the following:
* Known risk to prolong the QT interval or induce Torsade's de Pointes.
* Uncorrected hypomagnesemia or hypokalemia.
* Systolic Blood Pressure (SBP) \>160 mmHg or \<90 mmHg.
* Bradycardia (heart rate \<50 at rest), by ECG or pulse. On screening, inability to determine the QTcF interval on the ECG (i.e.: unreadable or not interpretable) or QTcF \>470 screening ECG
* Pregnant or breast-feeding women are excluded from this study because the safety of study medications is not established.
* Known HIV-positive participants on combination antiretroviral therapy are ineligible.
* These participants are at increased risk of lethal infections when treated with marrow-suppressive therapy. Separate HIV testing for this trial is not required. Similarly, separate Hepatitis B or C testing for this trial is not required, but patients with known (or history) of hepatitis B positive, or hepatitis C positive infection will be excluded
