Research/Clinical Interest
Dr. Friedman is a board certified Pediatric Hematologist/Oncologist who specializes in Pediatric Neuro-Oncology and conducting pediatric brain tumor research as a Scientist in the Neuro-Oncology Program of the UAB O'Neal Comprehensive Cancer Center. His overarching goal is to improve outcomes for children with malignant brain tumors by developing and improving novel, targeted immunotherapies like oncolytic engineered herpes simplex virotherapy (oHSV) in the lab and then translating these therapies to clinical trials. To maximize the benefit of oHSV to treat chemo- and radio-resistant pediatric brain tumors, his lab is focused on determining mechanisms of therapeutic resistance to oHSV by exploring the role of the tumor microenvironment and cellular defense mechanisms so that new viruses, unique routes of virus delivery, and combination therapies may be developed to circumvent resistance mechanisms. He is the Principal Investigator for the first pediatric trial of intratumoral oHSV alone or combined with radiation in children with recurrent/progressive malignant brain tumors ( identifier NCT02457845) and for the first-in-human trial of oHSV in pediatric recurrent/progressive malignant tumors in the cerebellum (NCT03911388)
