This is a phase 2, single-arm, open-label study to assess the safety and efficacy of once daily itacitinib oral administration in patients with diffuse large B-Cell lymphoma (DLBCL) who will receive CAR-T-cell therapy with axicabtagene ciloleucel (Axi-cel) and have been found to have high levels of systemic inflammation. Approximately n=27 adult males and females, 18 years or older, who will receive treatment for diffuse large B-cell lymphoma (DLBCL) at the Moffitt Cancer Center with a ferritin level greater than 400 ng/ml and C-reactive protein (CRP) level greater than 2 mg/dl (20 mg/l) at screening will be enrolled. Study regimen will consist of itacitinib 200 mg PO QD beginning at time of apheresis approximately 4-6 weeks prior to CAR-T-cell therapy and will continue until Day 30 (30 Days Post-CAR-T-cell therapy). The exact number of days between apheresis and CAR T cell infusion may vary based on CAR T cell manufacturing turnaround. A single infusion of axi-cel therapy will be administered on Day 0. Investigators hypothesize that pre-modulation with itacitinib started approximately 4 weeks prior to CAR-T-cell therapy with axi-cel will improve patient outcomes in those patients with diffuse large B-cell lymphoma (DLBCL) who express high levels of systemic inflammation.
The purpose of the study is to assess the safety and efficacy of once daily itacitinib oral administration in participants with diffuse large B-cell lymphoma (DLBCL) who will receive CAR-T cell therapy with axicabtagene ciloleucel (axi-cel).
