A Feasibility Study of Durvalumab +/- Oleclumab as Neoadjuvant Therapy for Muscle-invasive Bladder Cancer (BLASST-2)

Durvalumab is a monoclonal antibody (an antibody is a protein produced by the body's immune system) that works by blocking the Programmed Cell Death Ligand 1 (PD-L1), a protein on cancer cells that stops the body's immune system from killing cancer cells.

Oleclumab is a monoclonal antibody that works by reducing the amount of adenosine, a small molecule called a metabolite that binds to adenosine receptors on immune cells to regulate the immune system and suppress the immune response. Reducing the amount of immunosuppressive adenosine can increase the body's immune response to kill cancer cells.
