Research Interests

My laboratory’s research focuses on tumor immunobiology and the development/testing of novel immunotherapies for the effective treatment of cancer, with a near-term goal to develop innovative phase I/II clinical trials for the treatment of patients with melanoma or renal cell carcinoma (RCC). Such treatment modalities include dendritic cell (DC)-based vaccines and gene therapies that elicit specific T cell responses targeting tumor cells as well as stromal cell populations within the tumor microenvironment (TME). We discovered that immune targeting of the tumor-associated vasculature occurs naturally during effective immunotherapy, and that vaccines targeting tumor blood vessel antigens (TBVA) can safely promote tumor regression, even in cases where cancer cells themselves cannot be directly recognized by protective/therapeutic CD8+ T cells. We determined that combined treatment with anti-angiogenic agents leading to a state of tumor vascular normalization promotes a proinflammatory TME that recruits vaccine-induced T cells as well as adoptively transferred anti-tumor CTL. Such therapeutic conditioning of the TME also supports the formation of tertiary lymphoid structures (TLS) in association with slowed tumor growth or regression, with treatment extending overall survival in animal models and in a pilot phase II clinical trial (UPCI 12-048/NCT01876212) in patients with melanoma. We are currently investigating the use of IRF3 agonists (including STING agonists) delivered directly into the TME as components of in situ vaccines in the advanced disease setting with the intent to promote tumor-associated TLS neogenesis for improved local cross-priming of, and spreading in, therapeutic anti-tumor B cell and T cell repertoires.
