FORT WASHINGTON, PA—(Marketwired – January 27, 2016) – An unprecedented approach to clinical research, documented in the January issue of JNCCN — Journal of the National Comprehensive Cancer Network, brought together 32 researchers from 14 different institutions, including community and academic cancer centers, universities, and biotechnology and data sciences companies, to identify potential interventions for a patient with metastatic triple–negative breast cancer (TNBC) — an especially aggressive subset of breast cancer that is widely considered to be incurable. The Intensive Trial of OMics in Cancer (ITOMIC) deeply characterizes and tracks the molecular features of a patient's tumor, aggregates experts to generate hypotheses regarding treatments that are predicted to be beneficial, allows these predictions to be tested in the patient, and learns from these experiences to help future patients. This first report from ITOMIC describes a patient with triple–negative breast cancer metastatic to bone, who had markedly elevated circulating tumor cells (CTCs) that were monitored 48 times over nine months.

A team of multidisciplinary researchers, led by C. Anthony Blau, MD, Director of the Center for Cancer Innovation and Professor of Medicine, Division of Hematology, University of Washington School of Medicine in Seattle, biopsied multiple regions of the patient's tumor to perform whole–exome sequencing, RNA–sequencing, and deep sequencing of a panel of cancer associated genes. Data from these initial biopsies and from repeated samplings throughout the patient's disease course were shared on the cloud and accessed by researchers at different institutions with the goal of trying to find treatments that might help the patient.
“On a molecular level, every cancer is unique,” said Dr. Blau, a UW Medicine researcher. “By breaking down institutional barriers, this collaborative study brings a 'no–holds–barred' effort to trying to help an individual cancer patient using tools that virtually unite experts from around the world.”
According to Dr. Blau, the team found a high level of heterogeneity within the patient's tumor both at study entry and over the course of her disease. Researchers across a wide range of scientific disciplines and geographic locations weighed in, generating hypotheses regarding treatments to which the patient's tumor was predicted to respond.Â
Over the course of the patient's illness two hypotheses were generated. The first arose after surveying experts in Seattle; Boston; Portland, Oregon; Lawrence, Kansas; Taiwan; and Germany, and predicted that a U.S. Food and Drug Administration (FDA) approved drug used in certain forms of lung cancer might be effective. However, the drug costs nearly $10,000 per month, and since it is not approved for breast cancer, it would not be paid for by the patient's insurance company. With assistance from the research team the patient's doctor was able to obtain crizotinib from the manufacturer without cost; however, the prediction proved wrong, as the tumor did not respond. A second prediction emerged from the ad hoc development of a high throughput screen that tested the patient's circulating tumor cells against a panel of 160 drugs. Two inhibitors of a molecular target known as Bcl–2 were predicted to be effective, but researchers were unable to obtain either drug from the pharmaceutical manufacturers, even though these same drugs were being tested in clinical trials for other cancers. The patient died shortly thereafter.
“This case highlights the complexity involved and the investment required for implementing true precision medicine. It also underscores some of the challenges faced in bringing molecular medicine to the bedside,” said Margaret A. Tempero, MD, Editor–in–Chief, JNCCN. “As the practice of interrogating patient tumor samples for 'actionable' mutations grows, we have to simultaneously build principles for aligning this with evidence–based medicine in order to understand when to test, how to interpret, and most importantly, whom to treat.”
To date, 12 patients have enrolled in the University of Washington Center for Cancer Innovation study, which began in October 2013.
“The ITOMIC studies are about learning. While we pull out all stops to try to help our patients, we receive far more from our patients than we are able to give. The patients who enroll in this study, as exemplified by the patient described in this initial report, are true heroes. They are hugely motivated by the knowledge that their experience with cancer might help future generations of patients,” said Dr. Blau.
