Researchers Launch First Trial of Standard vs. Molecular Therapy for Pancreatic Cancer

“Pancreatic cancer is one of the few cancer types for which death rates are steadily increasing; it is projected to become the second leading cause of cancer-related death in the United States by 2030,” says Margaret Foti, PhD, chief executive officer of the AACR. The award recognizes “the urgent need for research into this deadly disease,” she says.

To that end, Georgetown Lombardi and Thomas Jefferson University are teaming up to conduct the first clinical trial that will compare standard of care chemotherapy with molecular tailored therapy.

Georgetown Lombardi oncologist and researcher Michael J. Pishvaian, MD, PhD, who co-leads the grant, says the trial will be the most comprehensive investigation to date of individualized therapy for pancreatic cancer.

“We have a dire need to develop new molecularly targeted therapies for pancreatic cancer, which is aggressive and difficult to successfully treat,” says Pishvaian. “This study will give us great insights into new therapies that might make a significant difference.”

There are likely several key molecular abnormalities driving individual patients’ cancers. But every patient’s tumor is different, and clinical trials group all patients together to test a novel therapy — irrespective of the unique characteristics of that patient’s tumor, he says. “Therefore, any potential promising results get diluted because novel therapies are not administered to those select patients who are most likely to respond, based on their tumors’ molecular profile. In this trial, we have the opportunity to treat every patient as unique, and to tailor each one’s therapy to each one’s tumor characteristics.”

The 60-patient randomized study, expected to begin this fall, will be conducted at five centers — Georgetown Lombardi, Cedars-Sinai in Los Angeles, Virginia Mason in Seattle, Mount Sinai in New York, and Thomas Jefferson University, with major scientific contributions from Emmanuel F. Petricoin, PhD, at George Mason University in Virginia.

A biopsy of each patient’s cancer will be screened for 600 genes as well as protein expression to uncover molecules and pathways that are driving the cancer and to predict a patient’s response to chemotherapy or other tailored therapy.

Once these analyses are completed, a “tumor board” of researchers and oncologists will help decide which therapies might work best for each individual patient.

“We are eager to immediately enhance patient outcomes by incorporating candidate and novel predictive tumor biomarkers into therapeutic decision making, making treatment rational and realistic,” Pishvaian says.

The research team will use novel laboratory techniques to further understand what is happening within each cancer biopsy, and how individual tumors will respond to therapy.

The research team will use novel laboratory techniques to further understand what is happening within each cancer biopsy, and how individual tumors will respond to therapy. This work will be conducted by Christopher Albanese, PhD and Stephen Byers, PhD, of Georgetown Lombardi.

Cancer modeling will be directed by the grant’s other co-leader, Jonathan R. Brody, PhD, of Thomas Jefferson University, and will include Subha Madhaven, PhD, director of clinical research informatics at Georgetown Lombardi and director of the Innovation Center for Biomedical Informatics at Georgetown.

“In the end, it may turn out that patients will do best with standard chemotherapy, and this is the only way to know if that is true — or if molecularly tailored therapy identifies more effective options,” says Pishvaian.

About Georgetown Lombardi Comprehensive Cancer Center
Georgetown Lombardi Comprehensive Cancer Center, part of Georgetown University Medical Center and MedStar Georgetown University Hospital, seeks to improve the diagnosis, treatment, and prevention of cancer through innovative basic and clinical research, patient care, community education and outreach, and the training of cancer specialists of the future.  Georgetown Lombardi is one of only 41 comprehensive cancer centers in the nation, as designated by the National Cancer Institute (grant #P30 CA051008), and the only one in the Washington, DC area.  For more information, go to http://lombardi.georgetown.edu.

About Georgetown University Medical Center
Georgetown University Medical Center (GUMC) is an internationally recognized academic medical center with a three-part mission of research, teaching and patient care (through MedStar Health). GUMC’s mission is carried out with a strong emphasis on public service and a dedication to the Catholic, Jesuit principle of cura personalis — or “care of the whole person.” The Medical Center includes the School of Medicine and the School of Nursing & Health Studies, both nationally ranked; Georgetown Lombardi Comprehensive Cancer Center, designated as a comprehensive cancer center by the National Cancer Institute; and the Biomedical Graduate Research Organization, which accounts for the majority of externally funded research at GUMC including a Clinical and Translational Science Award from the National Institutes of Health.
