About this study
Official title: Pilot Study To Investigate Targetable Metabolic Pathways Sustaining Triple Negative (TN) Breast Cancer and Associated Genomic Alterations
The primary objective is to describe and discover new insights into the glucose, amino acid, and lipid metabolic dependencies of TNBC via nuclear magnetic resonance (NMR) spectroscopy analysis of in vivo [1,2-13C] glucose-labeled breast cancer biopsies.
The secondary objectives are to correlate the dominant metabolic dependencies of TNBCs with pathologic response to preoperative chemotherapy, and with the cancers' molecular signaling pathways assessed via NGS and RPPA.
Read the detailed description
One of the recognized hallmarks of cancer cells is deregulated cellular metabolism, characterized by enhanced metabolic autonomy compare with non-transformed cells. Tumor cells typically display an overall increase in glucose metabolism, associated with enhanced aerobic glycolysis and decreased oxidative phosphorylation, accompanied by a requirement for a high rate of protein, nucleotide, and fatty acid synthesis to provide the raw materials for cell division. 13C-glucose is a non-radioactive stable isotope tracer that has been widely used in vitro, in vivo, and in patients in a variety of disease settings to study glucose, amino acid, and lipid metabolism, at steady state and following intervention. [1,2-13C] glucose can provide additional information on the activity of the oxidative pentose phosphate pathway versus glycolysis. Administration of intravenous 13C-glucose is a convenient and affordable approach to analyzing the metabolomics of human cancers in their native microenvironments.
The metabolic dependencies of the various breast cancer subtypes are poorly understood. Importantly, in depth analyses of the in situ metabolic processes utilized by triple-negative breast cancers (TNBCs) using state-of-the-art in vivo [1,2-13C]-glucose infusions in patients with TNBC has never been done. In TNBC, oncogenic activation of key signaling pathways leads to altered metabolic programming resulting in an increased dependence on exogenous nutrients such as glucose and glutamine. These data further suggest a hypothesis that TNBCs may employ a cellular mechanism called macropinocytosis to ingest and degrade interstitial albumin to accumulate glutamine. This process may then be exploited for therapeutic gain through enhanced uptake by cells that utilize macropinocytosis to meet their metabolic requirements.
In this study, administration of [1,2-13C]-glucose to patients with TNBC will be done prior to patients undergoing a biopsy of their breast cancer as well as blood sample collection which will allow for in depth evaluation of glycolysis as well as lipid and amino acid metabolism by Joshua Rabinowitz, PhD, at Princeton University who is an international expert in cancer metabolomics. RAS and PI3K pathway and other genomic alterations as well as pathway activation status will be determined by next generation sequencing (NGS) and by reverse phase protein array (RPPA), and will be correlated with the metabolic findings, and both will be assessed in the context of the patients' response to standard preoperative chemotherapy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
GlucoseDietary supplement
The first 4 patients enrolled on trial will undergo the research core biopsies of their TNBC without the 13C glucose infusion; these samples will serve as control tissue that will be processed identically to the tissues obtained from patients who received the glucose isotope.
The following 12 patients will receive 6 grams (g) of [1,2-13C] glucose as an IV
| Study group | Role | What they receive |
|---|---|---|
| Non Glucose Arm | Experimental | 4 patients without glucose infusion Receives: Dietary Supplement: Glucose |
| Glucose Arm | Experimental | 12 Patients with glucose infusion Receives: Dietary Supplement: Glucose |
What is being measured
The primary outcome is the main question the study is designed to answer.
Amount of glucose, amino acid, and lipid metabolites in TNBC.
Amount of glucose, amino acid, lipid will be measured in 16 patients with TNBC using NMR spectroscopy to see how metabolism is affected in TNBC.
Measured: 2 years
Secondary outcomes (1)
Correlation of signaling pathways in TNBC with response and metabolites.
A panel of key cancer cell signaling pathways will be analyzed in TNBC tissues from 16 patients using phosphoproteomic technology and next generation sequencing. The activated and deactivated pathways will be correlated with standard of care pathologic response (residual disease or no residual disease) and amount of glucose, amino acid, and lipid metabolized.
Measured: 2 years
