Some products have higher CRS toxicities than others. Tisa-cel, approved for pediatric ALL in 2018, was the first CAR T product approved by the FDA.Ĭytokine release syndrome (CRS), a common complication seen in patients receiving CAR T therapy, is noted in most CAR T trials. Medium duration of response has not been reached. All of these patients were minimal residual disease (MRD) negative. The complete remission rate was 60% and complete remission with incomplete hematologic recovery was 21%. Patients received fludarabine/cyclophosphamide or cytarabine/etoposide as their lymphodepleting chemotherapy, followed by cell infusion after completing lymphodepleting chemotherapy.

This trial investigated patients up to 21 years of age with refractory B-cell ALL in their second or later relapse. There are several important clinical trials for CAR T products that resulted in the drugs being approved, greatly increasing the therapeutic armamentarium against cancer:Įliana Trial for Tisa-Cel (NCT02435849) 1 Landmark CAR T Studies That Led to FDA Approvals Researchers are also hoping to see better outcomes as more specific targets for CAR T are investigated, and many trials are in antigen selection for various hematologic malignancies.

While results from these breakthrough CAR T therapies are promising, there are challenges to overcome, specifically around the tumor microenvironment, T cell exhaustion, and how to avoid cytokine release syndrome, a toxicity associated with the therapy. Ide-cel, the first CAR T-cell therapy for multiple myeloma, was approved in the past 2 years and has shown encouraging overall survival for this difficult disease. Multiple products are now on the market, including axicabtagene ciloleucel (axi-cel Yescarta), brexucabtagene autoleucel (brexa-cel Tecartus), tisagenlecleucel (tisa-cel Kymriah), lisocabtagene maraleucel (liso-cel Breyanzi), idecabtagene vicleucel (ide-cel Abecma) and ciltacabtagene autoleucel (cilta-cel Carvykti).These drugs have all been approved in the past decade, and more clinical trials are in progress. It has now been approved for use in adult relapsed/refractory non-Hodgkins lymphoma, multiple myeloma, and relapsed B-cell ALL. Early on it was investigated for B-cell ALL in pediatrics targeting CD19. Studies are also in progress for relapsed/refractory diffuse large B-cell lymphoma (DLBCL) where specific T-cell engagers are targeting CD19 or CD20.Ĭhimeric antigen receptor T-cell (CAR T) immunotherapy was next to emerge among immunotherapy in hematologic malignancies. This CD19-targeted BiTE (bispecific T-cell engager) therapy has been very well accepted, and now approved for relapsed/refractory B-cell ALL in adults. In 2018, blinatumomab (Blincyto) was approved for pediatric acute lymphocytic leukemia (ALL). Both are used in hematologic malignancies, with gemtuzumab ozogamicin targeting anti-CD33 and brentuximab vedotin targeting anti-CD30. These include the antibody-drug conjugates gemtuzumab ozogamicin (Mylotarg) and brentuximab vedotin (Adcetris).

More progress occurred in the 2010s when more monoclonal antibodies were approved.

This revolutionized how lymphomas were treated and became the new standard of care. In the 1990’s, rituximab (Rituxan), an anti-CD20 monoclonal antibody used in hematologic malignancies, was introduced. A closer look at the developments in immunotherapy may provide a greater understanding of the progress made so far, and the journey ahead. These therapies have revolutionized oncology, transforming how certain cancers are treated, but they have also created challenges along the way. Over the past several decades, numerous types of immunotherapy have emerged that seek to enhance natural defenses to eliminate malignant cells.
