CNS pharmaceuticals 6 Dr. Priebe is a Professor of Medicinal Chemistry in the Section of Immunobiology and Drug Carriers in the Department of Bioimmunotherapy at The University of Texas MD Anderson Cancer Center. Dr. Priebe is the inventor of more than 50 patents and the author of more than 200 scientific publications. As the founder or founding scientist of 6 pharmaceutical companies, including three listed on NASDAQ, Dr. Priebe has been integral in advancing several drugs through the pipeline, five of which entered clinical development. Dr. Priebe led the research that formed basis for the development of agents with high brain uptake (BBB crossing) and is the discoverer of our lead drug candidate Berubicin. Waldemar Priebe, PhD Dr. Hsu is fellowship trained and certified by the American Board of Psychiatry and Neurology, with extensive experience in the evaluation and treatment of neurological disorders in cancer patients. He specializes in primary brain tumors as well as brain and spinal cord metastases, cancer neurology and the treatment of chemotherapy neurotoxicity. His most recent research has focused on novel therapies for recurrent primary CNS lymphoma, recurrent glioblastoma multiforme and intralumbar injections for cancer therapy, and he has several patents granted and pending for his treatments. Most uniquely, Dr. Hsu personally treated patients with Berubicin in the Phase 1 clinical trial sponsored by Reata, including one patient with a durable complete response who is still alive today.
