A Study of CDX-585 in Patients With Advanced Malignancies

This study will determine the maximum tolerated dose of CDX-585 while also evaluating the safety, tolerability, and efficacy of CDX-585 in patients with cancer. Eligible patients that enroll to the dose-escalation portion of the study will be assigned to one of several dose levels of CDX-585. The dose-escalation part of the study will test the safety profile of CDX-585 and determine which dose of CDX-585 will be studied in the expansion portions of the study. All patients enrolled in the study will be closely monitored to determine if there is a response to the treatment as well as for any side effects that may occur. The expansion portion of the study will further evaluate the safety of CDX-585 in selected tumor types at the dose level chosen during the escalation part of the study.
