Descriptive Information
Brief Title  ICMJE A Study of CDX-1140 (CD40) as Monotherapy or in Combination in Patients With Advanced Malignancies
Official Title  ICMJE A Phase 1 Study of CDX-1140 as Monotherapy or in Combination in Patients With Advanced Malignancies
Brief Summary This is a study to determine the maximum tolerated dose (MTD) for CDX-1140 (CD40 antibody), either alone or in combination with CDX-301 (FLT3L), pembrolizumab, or chemotherapy and to further evaluate its tolerability and efficacy in expansion cohorts once the MTD is determined.
Detailed Description

This study will determine the MTD of CDX-1140 while also evaluating the safety, tolerability and efficacy of CDX-1140 alone (Part 1) or in combination with CDX-301 (Part 2), pembrolizumab (Part 3), or chemotherapy (Part 4) 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-1140. The dose-escalation part of the study will test the safety profile of CDX-1140, alone or in combination with CDX-301, pembrolizumab or chemotherapy and determine which dose(s) of CDX-1140 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.
