Clinical Trial Summary

This research study is being done to find out if the immunotherapy drugs called CDX-301 and CDX-1140 in combination with the standard chemotherapy treatment pegylated liposomal doxorubicin (PLD, Doxil) are safe and effective at controlling the cancer in patients with metastatic triple negative breast cancer, and to determine a safe dose and treatment schedule of the three drugs. This research study will also test how these treatments improve your body's immune response against the cancer.


Clinical Trial Description

The immunotherapy drugs CDX-301 and CDX-1140 in combination with the standard chemotherapy treatment PLD work by kickstarting the immune response against cancer cells. CDX-301 increases the antigen presenting immune cells needed to kickstart the immune response, CDX-1140 activates these cells, and chemotherapy helps release antigens from the cancer cells to train these antigen presenting immune cells to recognize the cancer for the immune system to attack it. Metastatic or unresectable triple negative breast cancer patients will receive this triplet combination that has been shown in preclinical studies to be more effective than the individual treatments or doublet combinations. To understand how the immunotherapies are working, some patients will receive the immunotherapy or chemotherapy only for one cycle prior to receiving the full triplet combination therapy. Ultimately, all patients will receive the triplet combination to study safety and how effective this treatment is at controlling triple negative breast cancer and improving survival outcomes. ;
