Axatilimab in Combination With Retifanlimab and Paclitaxel for the Treatment of Patients With Advanced or Metastatic Solid Tumors

This phase I/II trial tests the safety, side effects, and effectiveness of axatilimab in combination with retifanlimab and paclitaxel for the treatment of patients with a solid tumor that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) or that has spread from where it first started (primary site) to other places in the body (metastatic). Axatilimab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Immunotherapy with monoclonal antibodies, such as retifanlimab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Giving axatilimab in combination with retifanlimab and paclitaxel may be safe, tolerable and/or effective in treating patients with advanced or metastatic solid tumors.
