Primary Outcome Measures:
  • Dose limiting toxicity [ Time Frame: 28 Days ]
    A dose limiting toxicity is defined as any grade >=3 hematologic (except lymphopenia) or non-hematologic toxicity (except hypothyroidism or vitiligo) that, in the opinion of the investigator is considered at lease possibly related to the study treatment. If DLT is observed in greater than two patient in any cohort, then the previous cohort will be the maximal tolerated dose.

Secondary Outcome Measures:
  • Immune Response [ Time Frame: Pre-study, Days 5, 8, 15, 29, 36, 43, and 57. ]
    Blood tests and leukapheresis product will be collected to determine the response to three types of reporter antigens: (1) new antigen (keyhole limpet hemocyanin (KLH)), (2) recall protein antigen (tetanus), and (3) viral antigen (cytomegalovirus (CMV)). Changes in the number of antigens will be used to determine immune response.

Enrollment: 30
Study Start Date: November 2003

Detailed Description:
This study will evaluate the safety and determine the maximal tolerated dose of anti-OX40; evaluated the immune response to the study treatment; measure the pharmacokinetics of anti-OX40; monitor tumor regression, and identify the most biologically active dose of anti-OX40 to induce antigen-specific responses to a variety of immunogens.
