Tisagenlecleucel in adult relapsed or refractory follicular lymphoma: the phase 2 ELARA trial.

Tisagenlecleucel is an autologous anti-CD19 chimeric antigen receptor-T cell therapy with clinically meaningful outcomes demonstrated in patients with relapsed/refractory (r/r) B-cell lymphoma. In a previous pilot study of tisagenlecleucel in r/r follicular lymphoma (FL), 71% of patients achieved a complete response (CR). Here we report the primary, prespecified interim analysis of the ELARA phase 2 multinational trial of tisagenlecleucel in adults with r/r FL after two or more treatment lines or who relapsed after autologous stem cell transplant (no.

Tisagenlecleucel cellular kinetics, dose, and immunogenicity in relation to clinical factors in relapsed/refractory DLBCL.

The anti-CD19 chimeric antigen receptor (CAR)-T cell therapy tisagenlecleucel was evaluated in the global, phase 2 JULIET study in adult patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). We correlated tisagenlecleucel cellular kinetics with clinical/product parameters in 111 patients treated in JULIET. Tisagenlecleucel persistence in responders and nonresponders, respectively, was demonstrated for 554 and 400 days maximum by flow cytometry and for 693 and 374 days maximum by quantitative polymerase chain reaction (qPCR).

Tisagenlecleucel in relapsed/refractory diffuse large B-cell lymphoma patients without measurable disease at infusion.

Tisagenlecleucel demonstrated high rates of durable responses in adult patients with relapsed or refractory diffuse large B-cell lymphoma (r/r DLBCL) in the JULIET trial. Most patients (92%) received bridging therapies to control disease after study entry and before tisagenlecleucel infusion. Here, we examine the efficacy and safety of tisagenlecleucel in the subset of 7 patients who achieved complete response (CR) after bridging therapy and before tisagenlecleucel infusion.

Industry's Giant Leap Into Cellular Therapy: Catalyzing Chimeric Antigen Receptor T Cell (CAR-T) Immunotherapy.

Purpose Of Review: We describe the significant technological leap from bench to bedside that was achieved through a strong academic-industry collaboration between dedicated clinicians and researchers at the University of Pennsylvania, the Children's Hospital of Philadelphia, and Novartis to commercialize the chimeric antigen receptor T cell (CAR-T) therapy tisagenlecleucel (CTL019; Kymriah®; Novartis Pharma AG, Basel, Switzerland).

Recent Findings: Tisagenlecleucel was the first CAR-T therapy and the first gene therapy to receive US Food and Drug Administration approval in 2017, with an initial indication for pediatric and young adult patients with relapsed or refractory (r/r) acute lymphoblastic leukemia, followed by approval in May 2018 for a second indication in adult patients with r/r diffuse large B cell lymphoma. Subsequent approvals in the European Union, Switzerland, and Canada soon followed.

Tisagenlecleucel in Adult Relapsed or Refractory Diffuse Large B-Cell Lymphoma.

Background: Patients with diffuse large B-cell lymphoma that is refractory to primary and second-line therapies or that has relapsed after stem-cell transplantation have a poor prognosis. The chimeric antigen receptor (CAR) T-cell therapy tisagenlecleucel targets and eliminates CD19-expressing B cells and showed efficacy against B-cell lymphomas in a single-center, phase 2a study.

Methods: We conducted an international, phase 2, pivotal study of centrally manufactured tisagenlecleucel involving adult patients with relapsed or refractory diffuse large B-cell lymphoma who were ineligible for or had disease progression after autologous hematopoietic stem-cell transplantation.
