TPS3106 Background: Immune checkpoint blockade represents a novel form of cancer immunotherapy. Killer cell immunoglobulin-like receptors (KIR) and cytotoxic T lymphocyte antigen-4 (CTLA-4) are immune receptors that down-regulate NK and T cell activity, respectively. The anti-KIR antibody, lirilumab (BMSE986015), potentiates innate immunity by blocking signaling through inhibitory KIRs and has demonstrated modest side effects in a Phase I trial. The anti-CTLA-4 antibody, ipilimumab, potentiates adaptive immunity and has demonstrated improved overall survival in pts with advanced melanoma and preliminary evidence of clinical activity in Phase I and II trials. We hypothesized that coordinate modulation of innate and adaptive immunity by combining anti-KIR and anti-CTLA4 antibodies could achieve enhanced biologic and clinical activity compared to either agent alone. Here, we describe a Phase I study of lirilumab plus ipilimumab in pts with selected advanced solid tumors. Methods: This study will be performed in two parts and enroll approximately 150 pts. During dose escalation, pts with advanced melanoma, non-small cell lung cancer and castrate resistant prostate cancer, will be enrolled. During cohort expansion, 20 pts with each tumor type will be enrolled at the maximum tolerated dose (MTD), or the maximum administered dose, if no MTD is defined. The primary study objectives are to delineate the safety and tolerability, dose limiting toxicities, and MTD of this combination. Secondary objectives are to assess preliminary anti-tumor activity, pharmacokinetics, and immunogenicity of this combination in all pts, and the pharmacodynamic effects on tumor infiltrating lymphocytes in a cohort of melanoma pts. Exploratory objectives include a thorough assessment of the modulation of innate and adaptive immunity by this combination in peripheral blood and/or tumor specimens, and preliminary evaluation of the association of these changes with clinical outcome. Clinical trial registration number: NCT01750580 Clinical trial information: NCT01750580.
