Celldex Therapeutics reported data from its ongoing Phase 1 study of the fully human monoclonal antibody varlilumab in cancer. Varlilumab is an immunotherapy designed to enhance the body's natural immune response by directly activating T cells that can specifically recognize and kill cancer cells. Preclinical data support the broad study of varlilumab in combination with a number of other anti-cancer agents including but not limited to checkpoint inhibitors, chemotherapies, targeted therapies and vaccines. Varlilumab will enter at least four combination studies in the second half of 2014. Results presented included data from the lymphoid malignancies dose-escalation arm and solid tumor expansion cohorts in metastatic melanoma and renal cell carcinoma. Varlilumab was very well tolerated and demonstrated clear biologic activity and promising signs of clinical activity in advanced, treatment-refractory patient populations—all of which provide the rationale for combination studies with other immune activating therapies. Results were presented in two poster sessions at the American Society of Clinical Oncology Annual Meeting 2014 on Monday, June 2, from 1:15 to 4:15 p.m. CDT. In addition, the data will be discussed during a Poster Highlight Session entitled "Modulating the Anti-tumor Immune Response" by Dr. Cassian Yee of The University of Texas MD Anderson Cancer Center at 5:15 CDT.
