21 EW NEWS & OPINION January 2019 and has shown impressive response in rabbits," Dr. Shields said. "We are in Phase 1b safety trials and efficacy trials are to begin soon. We have treated seven patients at Wills Eye Hospital. We might be able to treat smaller and smaller tumors with this modality. This is a new era of mela- noma treatment and prevention." Melanoma metastasis are target- ed with immune modulated T-cells against cancer. Dr. Shields elucidat- ed, "We use this every week. It is a receptor that attaches itself to mela- noma cells and attracts T-cells to it, causing necrosis of the melanocyte. We are learning to use this together with checkpoint inhibitors for better results for uveal melanoma." Tumor biomarkers A biomarker is a measurable indi- cator of a biological condition or disease, used in the pharmacological industry to design targeted drugs. There are a number of known biomarkers in ocular oncology, just as the well known biomarkers that identify breast, ovarian, and colorec- tal cancers. "We test for all of the known biomarkers, but we do not have specific medications for all of them. Recognizing conjunctival tu- mors and understanding predispos- ing factors, biomarkers, and treat- ment strategies are vital to patient outcomes. 6 These are exciting times in oncologic ophthalmology," Dr. Shields said.
