• Registration Number: NCT03373188
• Lead Sponsor: Emory University

Brief Summary

This randomized phase I trial studies how well anti-semaphorin 4D (anti-SEMA4D) monoclonal antibody VX15/2503 with or without ipilimumab or nivolumab work in treating patients with stage I-III pancreatic cancer that can be removed by surgery or stage IV colorectal cancer that has spread to the liver and can be removed by surgery. Monoclonal antibodies, such as anti-SEMA4D monoclonal antibody VX15/2503, ipilimumab, and nivolumab, may interfere with the ability of tumor cells to grow and spread.

Detailed Description

PRIMARY OBJECTIVE:

To evaluate the effect of the anti-SEMA4D monoclonal antibody VX15/2503 (VX15/2503) alone and VX15/2503 in combination with immune checkpoint inhibitors, ipilimumab or nivolumab, on the immune profile in the tumor microenvironment and in peripheral blood.

SECONDARY OBJECTIVE:

To extend the previously reported safety profile of single agent VX15/2503 to the combination of VX15/2503 and immune checkpoint inhibitors, ipilimumab or nivolumab, in patients with pancreatic and colorectal cancer.

OUTLINE:

Patients are randomized to 1 of 4 arms.

ARM I: Patients undergo surgery.

ARM II: Patients receive anti-SEMA4D monoclonal antibody VX15/2503 intravenously (IV) over 60 minutes on day 1. Patients then proceed to surgery 22-36 days after drug administration.

ARM III: Patients receive anti-SEMA4D monoclonal antibody VX15/2503 IV over 60 minutes and ipilimumab IV over 90 minutes on day 1. Patients then proceed to surgery 22-36 days after drug administration.

ARM IV: Patients receive anti-SEMA4D monoclonal antibody VX15/2503 IV over 60 minutes and nivolumab IV over 60 minutes on day 1. Patients then proceed to surgery 22-36 days after drug administration.

After completion of study treatment, patients are followed up at 90 days and then every 12 weeks thereafter.

Exclusion Criteria

• Poor venous access for study drug administration

• Treatment with chronic immunosuppressants (e.g., cyclosporine following transplantation)
• Prior organ allograft or allogeneic bone marrow transplantation
• Subjects with any active autoimmune disease or history of known or suspected autoimmune disease except for subjects with vitiligo, resolved childhood asthma/atopy, type I diabetes mellitus, residual hypothyroidism, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll
• Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration; inhaled or topical steroids and adrenal replacement doses > 10 mg daily prednisone equivalents are permitted in the absence of active autoimmune disease
