About me

Geoffrey T. Gibney, MD, is a co-leader of the Melanoma Disease Group at MedStar Georgetown University Hospital and is a member of the Developmental Therapeutics (Phase I) program. He is well known for treating patients with advanced non-melanoma skin cancers (basal cell carcinoma, squamous cell carcinoma and merkel cell carcinoma), renal cell carcinoma and other rare skin cancers. Dr. Gibney is board certified in both internal medicine and medical oncology. He was previously a faculty member in the Department of Cutaneous Oncology at the Moffitt Cancer Center in Tampa.

Dr. Gibney’s area of expertise also includes the first of its kind TIL (Tumor Infiltrating Lymphocyte) therapy for metastatic melanoma, now available at MedStar Georgetown.

Dr. Gibney is recognized for his advanced melanoma research. He is currently involved in several clinical trials focused on developing novel immunotherapy and targeted therapy strategies. Past clinical research has included the study of anti-PD-1 therapy to prevent recurrences of resected melanoma, combination immunotherapies (such as ipilimumab plus the novel IDO1 inhibitor, epacadostat) to enhance the clinical benefit in advanced melanoma patients and combination BRAF targeted therapy to overcome drug resistance.

His current goal is to develop biomarker-driven approaches for personalized therapeutic strategies in patients with advanced malignancies.

MedStar Georgetown is part of the MedStar Georgetown Cancer Institute, which combines medical expertise, the latest therapies, and research across MedStar Health. Our research engine, the Georgetown Lombardi Comprehensive Cancer Center, is the only National Cancer Institute-designated comprehensive cancer center in the Washington, D.C., region. This partnership means we provide access to cutting-edge clinical trials and the latest breakthroughs in cancer care.
