Help With Holidays For Disabled Adults. On August 3. 0, the Food and Drug Administration (FDA) approved a type of immunotherapy called CAR T- cell therapy for certain children and young adults with a form of acute lymphoblastic leukemia (ALL). The treatment, tisagenlecleucel (Kymriah™), is the first CAR T- cell therapy to receive FDA approval.
Acute lymphoblastic leukemia is the most common cancer among children in the United States. Intensive chemotherapy cures more than 8.
ALL that arises in B cells, which is the predominant type of pediatric ALL. But there are few treatment options for patients whose cancers do not respond to treatment or go into remission and later relapse. FDA approved tisagenlecleucel, which is manufactured by Novartis, for patients up to 2.
B- cell ALL that does not respond to treatment or has relapsed two or more times. The treatment is customized for each patient using the patient’s T cells, which are genetically modified to enhance their ability to recognize and attack cancer cells. The process takes about 2. High Remission Rates with Tisagenlecleucel. The approval of tisagenlecleucel was based on a multicenter clinical trial involving 6.

A trial at Seattle Children’s is currently testing T-cell therapy in infants, children and young adults with relapsed or refractory acute lymphoblastic leukemia. Original Article.

D., Ph. D., who led the trial at CHOP, said in a statement. Another CAR T cell therapy, produced by Kite Pharma, is expected to be approved later this year for the treatment of some patients with lymphomas. With the success seen in blood cancers, researchers at NCI and other organizations are busy developing ways to expand the use of CAR T- cell therapies. “We hope the momentum behind the technology builds as we continue to investigate the abilities of personalized cellular therapeutics in blood cancers and solid tumors to help patients with many other types of cancer,” Carl June, M. D., of the University of Pennsylvania Abramson Cancer Center, who led the early development of tisagenlecleucel, said in a statement.

A Personalized Therapy. The first step in creating tisagenlecleucel is to isolate T cells from a patient’s blood. These are shipped to a cell- processing plant.
There, the cells are genetically engineered so that they will produce a protein called a chimeric antigen receptor, or CAR, which allows the cells to attach to a protein on tumor cells called CD1. The modified cells are then grown, or expanded, into hundreds of millions of cells and shipped back to the patient’s physician. Finally, after patients undergo a "lymphodepleting" chemotherapy, they receive the infusion of the engineered immune cells. If the treatment works as intended, the CAR T cells will continue to multiply, increasing the therapy’s potential for eradicating the cancer. CAR T cells and TCR T cells are engineered to produce special receptors on their surfaces. They are then expanded in the laboratory and returned to the patient.

Some patients in the trial experienced serious side effects associated with the treatment, and Novartis will include a “boxed warning” to alert physicians to the potential health risks. The infusion of CAR T cells can lead to inflammatory side effects—known collectively as cytokine release syndrome (CRS)—that range from high fevers and mild flu- like symptoms to life- threatening drops in blood pressure, vascular leakage, and kidney problems. In addition, neurological events, such as confusion and seizures, are also possible and may be life threatening. In the trial that led to FDA approval, CRS was managed using the arthritis drug tocilizumab (Actemra).“Actemra seems to blunt the symptoms of CRS in the vast majority of patients,” said Christian Capitini, M. D., of the University of Wisconsin (UW) School of Medicine and Public Health, who treated participants in the clinical trial at the American Family Children’s Hospital at UW.

FDA has now expanded the approval of tocilizumab to treat severe or life- threatening CRS in patients over the age of 2. In clinical trials involving CAR T cells, 6. CRS within two weeks, according to FDA.“The neurological side effects in patients seem to resolve on their own,” Dr.
Capitini said. “But it’s something we have to watch for.”FDA is requiring that institutions offering tisagenlecleucel be certified to demonstrate that they have the expertise to treat patients and monitor them for potential side effects.
