APX005M With Concurrent Chemoradiation for Resectable Esophageal and Gastroesophageal Junction Cancers

Completed · Phase 2

Conditions studied: Esophageal Cancer, GastroEsophageal Cancer

In brief

This pilot phase II trial studies the therapeutic effects and side effects of CD40 agonistic monoclonal antibody APX005M when combined with chemotherapy and radiation therapy, and to see how well they work to reduce or remove esophageal or gastroesophageal (GE) cancers when given before surgery in treating patients with esophageal cancer or GE cancer than can be removed by surgery. APX005M is intended to stimulate the body's own immune system so that the immune cells can more effectively invade and destroy the tumor, adding to the benefits of the chemotherapy and radiation therapy. Drugs used in chemotherapy, such as carboplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving APX005M, chemotherapy, and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Age ≥ 18 years of age.
Histologically proven squamous cell carcinoma, adenocarcinoma or undifferentiated carcinoma of the esophagus or GE junction.
Surgically resectable (T1-3 Nx preferably by endoscopic ultrasound [EUS]). (Excluded: T1N0 tumors, cervical esophageal location, tumors invading the tracheobronchial tree or with fistula, distant disease that cannot be included in the radiation field or be resected at the time of esophagectomy).

Adequate hematological, renal, and hepatic parameters.

You may not qualify if…

Any history of or current hematologic malignancy.
History of a second primary cancer is allowed in the event the cancer is curatively resected and there is no evidence of recurrence/metastatic disease x 1 year. Subjects who have a history of cervical or breast carcinoma in situ, localized prostate cancer, adequately treated basal cell or squamous cell carcinoma of the skin, or superficial bladder tumors [Ta, Tis \& T1] are also allowed.
Major surgery within 4 weeks of first dose of investigational product.
Prior or concurrent treatment with any anticancer agent for the same cancer diagnosis.
Prior exposure to any immuno-oncology agents, including CD40/PD-1/PD-L1/CTLA-4 inhibitors (if any ambiguity, should be discussed with study principal investigator).
History of bone marrow transplantation.
History of autoimmune disorders with the exception of vitiligo or autoimmune thyroid disorders.
Chronic steroid dependency (prednisone equivalent > 10 mg/day). Any steroid use should be discontinued at least 2 weeks prior to initiation of study treatment.
Congestive heart failure (New York Heart Association Class III to IV), symptomatic ischemia, conduction abnormalities uncontrolled by conventional intervention, or myocardial infarction within 6 months before first dose.
Known human immunodeficiency virus (HIV) infection.
