This study evaluates APX005M, in combination with chemoradiation, in patients with resectable cancers of the esophagus and gastroesophageal (GE) junction, including both squamous cell and adenocarcinomas.

Official Title

A Pilot Study of APX005M in Combination With Concurrent Chemoradiation as Neoadjuvant Therapy for Resectable Esophageal and Gastroesophageal Junction Cancers


This is a non-comparative open-label multicenter pilot study of APX005M in patients with resectable (T1-3N0-1, excluding T1N0) cancers of the esophagus and GE junction, including both squamous cell and adenocarcinomas.

Safety and toxicity will be assessed on a continuous basis throughout the course of study treatment by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.03.

Regular clinical assessments will be performed throughout the course of study treatment, including physical exams, CT-PET scan at the completion of chemoradiation, and assessment of pathologic response at the time of surgery.

Immunotherapeutic approaches have demonstrated clear evidence of therapeutic activity in a subset of patients with advanced gastroesophageal cancers. CD40 agonistic antibodies represent an attractive and novel form of immunotherapy that stimulate an immune response by activating antigen processing and presentation, recruiting immune effectors such as natural killer (NK) cells and macrophages, and additionally have direct cytotoxic effects on tumor cells. However, the activity of this class of agents in esophageal/GE junction cancers is unknown and will be evaluated in the context of this study by combining it with standard chemoradiation in the neoadjuvant setting, with serial collection of tissue and blood along the way for correlative purposes to monitor on-target treatment and pharmacodynamics effects. This study represents the first of its kind to evaluate the safety and preliminary efficacy of combining a CD40 agonist antibody with standard chemoradiation in patients with resectable disease.
