Almost 80% of patients with treatment-refractory non-Hodgkin lymphoma had objective responses following treatment with KTE-C19, a chimeric antigen receptor T-cell therapy targeting CD19.

Chimeric antigen receptor (CAR) T-cells have been dramatically effective in treating B-cell cancers, according to David L. Porter, MD, of the University of Pennsylvania Health System. He also identified the use of CAR T-cells for treating solid tumors as a research area that will see more development in the coming years.

An investigational anti-BCMA chimeric antigen receptor T-cell therapy demonstrated an objective response rate of 78% in patients with relapsed/refractory multiple myeloma.

For a second time, a clinical hold has been placed on the phase II ROCKET study exploring the CD19-targeted CAR T-cell therapy JCAR015 for adult patients with relapsed or refractory B cell acute lymphoblastic leukemia.

Chimeric antigen receptor T-cell therapy targeting CD19 demonstrated a nearly 80% complete remission rate across relapsed/refractory B-cell acute lymphoblastic leukemia patients with multiple levels of disease burden.

After less than a week, the FDA has lifted a clinical hold placed on the phase II ROCKET study that is exploring the CAR T-cell therapy JCAR015 for adult patients with relapsed or refractory B cell acute lymphoblastic leukemia.

During a session on the second day of the annual meeting of the American Society of Clinical Oncology, experts discussed treating patients with chimeric antigen receptor T cells (CAR-T cells).

Chimeric antigen receptor-modified T-cell therapies have demonstrated durable complete responses for patients with relapsed/refractory B-cell acute lymphoblastic leukemia; however, several questions remain regarding their optimal use and applicability outside of this disease.

The FDA has approved Captisol-enabled melphalan (Evomela) as a high-dose conditioning treatment for use in patients with multiple myeloma prior to autologous stem cell transplantation, as well as for the palliative treatment of patients with myeloma for whom oral therapy is not appropriate.

Two CD19-targeted chimeric antigen receptor-modified T-cell therapies demonstrated complete response rates ranging from 90% to 100% in patients with high-risk acute lymphoblastic leukemia.

Updated findings from early stage clinical trials exploring chimeric antigen receptor-modified T-cell therapies continue to highlight the effectiveness of these approaches for patients with non-Hodgkin lymphoma.

Though clinical work is ongoing and early, researchers are already considering how to manage potentially fatal neurotoxicities in patients treated with chimeric antigen receptor T-cell therapy

Infusions of CTL019 achieved durable responses and showed an acceptable safety profile in heavily pretreated patients with CD19-positive non-Hodgkin lymphoma.

Infusions of Epstein-Barr virus (EBV)–specific cytotoxic T lymphocytes from healthy donors led to high response rates and significant extensions in overall survival for patients with rituximab-refractory EBV–associated lymphoproliferative disorders.

Chimeric antigen receptor T-cell therapy is an immunotherapy in which the patient's own T cells are isolated in the laboratory, redirected with a synthetic receptor to recognize a particular antigen or protein, and reinfused into the patient.

Pfizer's deal with the French company will ensure a market share in the promising immunooncology field.

Ventana Medical Systems, Inc. and MedImmune today announced they are jointly developing a PD-L1 (SP263) immunohistochemistry assay to enroll patients in clinical trials for MedImmune's MEDI4736 anti-PD-L1 therapy for non-small cell lung carcinoma. This includes the recently commenced MEDI4736 ATLANTIC trial that will enroll only patients who express PD-L1 as determined by the VENTANA assay.
