CAR-T cell therapy CTL019 recommended for approval by FDA advisory committee to treat paediatric, young adult r/r B-cell ALL

Novartis announced that the US Food and Drug Administration (FDA) Oncologic Drugs Advisory Committee (ODAC) unanimously (10-0) recommended approval of CTL019 (tisagenlecleucel), an investigational chimeric antigen receptor T cell (CAR-T) therapy, for the treatment of relapsed or refractory (r/r) paediatric and young adult patients with B-cell acute lymphoblastic leukaemia (ALL).

“The panel’s unanimous recommendation in favour of CTL019 moves us closer to potentially delivering the first-ever commercially approved CAR-T cell therapy to patients in need,” said Bruno Strigini, CEO, Novartis Oncology. “We’re very proud to be expanding new frontiers in cancer treatment by advancing immunocellular therapy for children and young adults with r/r B-cell ALL and other critically ill patients who have limited options. We look forward to working with the FDA as they complete their review.”

Acute lymphoblastic leukaemia comprises approximately 25% of cancer diagnoses among children under 15 years old and is the most common childhood cancer in the US1.

Effective treatment options for patients with r/r ALL are limited.

In paediatric and young adult patients with B-cell ALL that have relapsed multiple times or become refractory to treatment, the five-year disease-free survival is less than 10-30%2,3,4.

The ODAC recommendation is based on review of the CTL019 r/r B-cell ALL development program, which includes the Novartis-led ELIANA study (NCT02435849), the first paediatric global CAR-T cell therapy registration trial.

Findings from a US multicenter trial and a single site trial examining the safety and efficacy of CTL019 among paediatric and young adult patients with r/r B-cell ALL also supported the recommendation and the Biologics License Application (BLA)5.

CTL019 was first developed by the University of Pennsylvania (Penn) and uses the 4-1BB costimulatory domain in its chimeric antigen receptor to enhance cellular responses as well as persistence of CTL019 after it is infused into the patient, which may be associated with long-lasting remissions in patients.

In 2012, Novartis and Penn entered into a global collaboration to further research, develop and commercialise CAR-T cell therapies, including CTL019, for the investigational treatment of cancers. Children’s Hospital of Philadelphia (CHOP) was the first institution to investigate CTL019 in the treatment of paediatric patients and led the single site trial.

“It is encouraging to see the FDA panel’s recommendation and continued momentum behind this innovative therapy, which has potential to help young patients with relapsed/refractory B-cell ALL,” said the Penn team's leader, Carl June, MD, the Richard W. Vague Professor of Immunotherapy, director of the Center for Cellular Immunotherapies in Penn’s Perelman School of Medicine and director of the Parker Institute for Cancer Immunotherapy at Penn. “We look forward to continuing to work with Novartis to help make a lasting impact on the way this disease is treated.”

“We know firsthand from treating children and young adults with relapsed/refractory B-cell ALL that they desperately need innovative medicines that provide a new approach to managing this aggressive disease,” said Stephan Grupp, MD, PhD, the Yetta Deitch Novotny Professor of Paediatrics at the Perelman School of Medicine at Penn, Director of the Cancer Immunotherapy Frontier Program and Chief of the Section of Cellular Therapy and Transplant at CHOP. “Today’s vote in favour of CTL019 is a positive step and we appreciate Novartis’ commitment to paediatric patients.”
