Axicabtagene ciloleucel is a chimeric antigen receptor T cell (CAR T) therapy, which harnesses a patient’s own immune system to fight certain types of blood cancer. The cell therapy has been proven to induce complete response (no detectable cancer) in a proportion of patients with relapsed or refractory DLBCL and PMBCL, which are aggressive forms of non-Hodgkin lymphoma (NHL).

“Axicabtagene ciloleucel is a new and exciting way of treating cancer that offers a new option to patients with DLBCL and PMBCL in Europe,” said Professor Gilles Salles, Head of Hematology, South Lyon Hospital Complex. “Many patients with these aggressive forms of non-Hodgkin lymphoma who have not responded to or failed commonly available treatment options have a very poor prognosis and there is an urgent need for new therapies.”

The Marketing Authorization Application (MAA) is supported by data from the ZUMA-1 trial of axicabtagene ciloleucel in adult patients with refractory aggressive NHL. In the single-arm trial, 72 percent of patients (n=73/101) who received a single infusion of axicabtagene ciloleucel responded to therapy, with 51 percent (n=52/101) achieving a complete response (as assessed by an independent review committee, median follow-up of 15.1 months). At one year following infusion, 60 percent of patients were alive (95% CI: 50.2, 69.2) and the median overall survival (OS) had not been reached (95% CI: not estimable [NE]).

Axicabtagene ciloleucel may cause side effects that are severe or life threatening, such as cytokine release syndrome (CRS) or neurological toxicities. In ZUMA-1, 12 percent of patients experienced Grade 3 or higher CRS and 31 percent experienced Grade 3 or higher neurologic toxicities. Overall 98 percent of patients recovered from CRS and/or neurologic adverse reactions. Treatment algorithms have been developed to manage some of the symptoms associated with both CRS and neurologic adverse reactions experienced by patients on axicabtagene ciloleucel.

The most common Grade 3 or higher adverse reactions include encephalopathy, unspecified pathogen infection, CRS, bacterial infection, aphasia, viral infection, delirium, hypotension and hypertension.

“We are proud to be leading this frontier of cancer innovation that is bringing novel, personalized therapy to people living with these blood cancers,” said Alessandro Riva, MD, Gilead's Executive Vice President, Oncology Therapeutics & Head, Cell Therapy. “Our vision is for cell therapy to serve as the foundation for treating all cancer types. Today’s milestone is another step on this exciting and important journey.”

Axicabtagene ciloleucel was approved by the U.S. Food and Drug Administration on October 18, 2017.
