Victor Villalobos MD, PhD

Medical oncologist, Sarcoma specialist

Instructor, Medicine - Oncology
My clinical interests lie predominantly in treating rare tumors. I have special interest in diagnosing and treat unknown primary cancers (occult primary carcinoma), sarcoma and refractory ovarian cancers. I also am deeply involved in developmental therapeutics and early phase clinical studies. Currently I am running a phase I study of CDX-1127, a T-cel activating therapy in, B cell malignancies, renal cell carcinoma, and melanoma. Outside of my clinical work, I collaborate with Dr. Branimir Sikic on developing predictive biomarkers in ovarian cancers.
