Using Phase 0 Trials to Bring Precision Medicine to Treating Brain Tumors

More than 138,000 people in the United States and 1.4 million people worldwide are struggling with malignant brain tumors. The average five-year survival rate of people with the most common malignant brain tumor—glioblastoma multiforme—is less than 5 percent and there have been no notable improvements in the last three decades. The Ivy Brain Tumor Center is using phase 0 clinical trials to provide individualized treatment to patients with brain tumors. The U.S. Food and Drug Administration introduced phase 0 trials in 2004 to address concerns about the slow pace and high cost of drug development. The phase 0 trial is used to quickly identify how a drug works in a patient and whether it should be fast-tracked for further development. We spoke to Nader Sanai, director of the Ivy Brain Tumor Center and chief of neurosurgical oncology at the Barrow Neurological Institute, about phase 0 clinical trials, how they work, and how they are allowing the center to take a precision medicine approach to treating patients with brain tumors.
