Fellowship-trained oncologist, Dr. O’Sullivan Coyne, is a Staff Clinician in the Early Clinical Trials Development Program and a faculty member since joining Developmental Therapeutics Clinic (DTC) in 2016. 

Located in Bethesda, Maryland, the DTC focuses on conducting phase 0 to phase II and biomarker-driven clinical trials while providing exceptional clinical care to the patients participating in our studies. Their mission is to perform groundbreaking research studies of new treatments for cancer. The clinic specializes in novel therapeutic approaches that focus on understanding the mechanism of action of new treatments using advanced genomic and pharmacodynamic assays. The ultimate goal is to improve understanding of new cancer therapies early so the information can be used to improve the selection of patients, combinations, and schedules for the development of more efficacious phase II and phase III trials.

From 2012 until 2015, she performed her fellowship in medical oncology at the National Institutes of Health Clinical Center.

Most recently, Dr. O’Sullivan Coyne was awarded the Society of Connective Tissue Oncology (CTOS) Young Investigator in 2018 for her work with immunotherapy in a rare sarcoma subtype. At DTC, she continues to pursue her interest in developing novel cancer therapies using pharmacokinetic and pharmacodynamic tools to impulse drug development.

Oncology is a branch of medicine that deals with the prevention, diagnosis, and treatment of cancer. A medical professional who practices oncology is an oncologist. An oncologist is a doctor who treats cancer and provides medical care for a person diagnosed with cancer. They lead a cancer treatment team of various healthcare professionals, treat patients with radiation therapy, coordinate treatment plans and prescribe various types of treatment, including chemotherapy and immunotherapy, as well as assist patients with pain management.
