RATIONALE: Monoclonal antibodies, such as ticilimumab and CD40 agonist monoclonal antibody CP-870,893, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry cancer-killing substances to them. Giving ticilimumab together with CD 40 agonist monoclonal antibody CP-870, 893 may kill more tumor cells.
I. To assess the safety, dose-limiting toxicities and maximum tolerated doses of tremelimumab (administered intravenously every 12 weeks) and CP- 870,893 (administered intravenously every 3 weeks).
I To seek preliminary evidence of anti-tumor efficacy of the combination of tremelimumab and CP-870,893, including objective response rate at MTD.
II. To determine the immune pharmacodynamic changes associated with the administration of the combination of tremelimumab and CP-870,893.
OUTLINE: Patients receive ticilimumab IV over 1 hour on day 1 and CD40 agonist monoclonal antibody CP-870,893 IV over 30 minutes on days 2, 22, 43, and 64. Treatment repeats every 12 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed for 4 weeks.

A membrane glycoprotein and differentiation antigen expressed on the surface of T-cells that binds to CD40 ANTIGENS on B-LYMPHOCYTES and induces their proliferation. Mutation of the gene for CD40 ligand is a cause of HYPER-IGM IMMUNODEFICIENCY SYNDROME, TYPE 1.
A member of the tumor necrosis factor receptor superfamily with specificity for CD40 LIGAND. It is found on mature B-LYMPHOCYTES and some EPITHELIAL CELLS, lymphoid DENDRITIC CELLS. Evidence suggests that CD40-dependent activation of B-cells is important for generation of memory B-cells within the germinal centers. Mutations of the gene for CD40 antigen result in HYPER-IGM IMMUNODEFICIENCY SYNDROME, TYPE 3. Signaling of the receptor occurs through its association with TNF RECEPTOR-ASSOCIATED FACTORS.
An anti-VEGF recombinant monoclonal antibody consisting of humanized murine antibody. It inhibits VEGF receptors and prevents the proliferation of blood vessels.
A form of fluorescent antibody technique commonly used to detect serum antibodies and immune complexes in tissues and microorganisms in specimens from patients with infectious diseases. The technique involves formation of an antigen-antibody complex which is labeled with fluorescein-conjugated anti-immunoglobulin antibody. (From Bennington, Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)
A form of fluorescent antibody technique utilizing a fluorochrome conjugated to an antibody, which is added directly to a tissue or cell suspension for the detection of a specific antigen. (Bennington, Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984)
