Targeting tumor stem cells

Clinical trial at the University of Cincinnati involves targeting stem cells for personalized treatment of brain cancer

Researchers at the University of Cincinnati are leading the local arm of a study looking at ways to test for chemosensitivity in brain tumor stem cells to determine treatment response and outcomes for patients.

The primary site for the clinical trial is Marshall University in West Virginia, but Nicholas Marko, MD, director of the UC Brain Tumor Center, is leading the study locally.

“We are collecting tumor tissue from our patients and sending it to our collaborators at Marshall,” says Marko, who is also an associate professor of neurosurgery at the UC College of Medicine and a member of both the Gardner Neuroscience and Cancer Institutes. “These researchers grow stem cells from the tumor and then try to kill those cells with a number of chemotherapy drugs. The therapy that works best, based on these outcomes, is the patient’s designated study drug.” 

Marko says when glioblastoma, an extremely malignant form of brain tumor, recurs in patients, the treatment options are often minimal, as surgery and radiation are not usually a possibility.

“In this study, patients with recurrent glioblastoma will receive standard therapy, including surgery if the tumor can be removed, and for the chemotherapy portion of their treatment, participants will be randomized between treatments chosen by the physician—standard cancer treatments—or the personally-selected, chemosensitivity drug. The goal is to see if this personalized therapy is more effective than standard of care.

“The idea is similar to when we test for bacterial sensitivity against antibiotics, in case of a bacterial infection. The test, in this case, uses sample specimens obtained following surgery for the treatment of brain cancer.”

Marko says that participants will be assessed by either brain MRI with contrast or CT scans at two to three month intervals after therapies are administered.

“The hope is that this study will lead to more personalized, targeted treatment for patients with a very serious cancer,” he says.

This study is being funded by ChemoID. Marko cites no conflict of interest.
