Dr. Brigitte Widemann is a pediatric oncologist with the primary interest of developing effective therapies for children and adults with genetic tumor predisposition syndromes, such as neurofibromatosis type 1 (NF1), and rare solid tumors through innovative clinical trial design. Dr. Widemann currently serves as the head of the Pharmacology & Experimental Therapeutics Section and as Chief of NCI’s Pediatric Oncology Branch. Dr. Widemann is also a medical advisor to a new NCI initiative to Advance RASopathy Therapies (ART) and serves as Special Advisor on Childhood Cancer to the NCI Director.  

Anticancer drug discovery and development are moving towards a more rational and targeted approach. The application of new molecularly targeted agents to the treatment of childhood cancers and neurofibromatosis type 1 (NF1) is a research objective of the Pharmacology & Experimental Therapeutics Section (PETS). In addition to studying the pharmacology, pharmacokinetics, pharmacodynamics, and toxicities of these novel agents, it is also a goal of the PETS to evaluate novel clinical trial designs and trial endpoints, which may be more applicable for molecularly targeted agents.
