Basel, June 12, 2022 Novartis today announced long-term results from the ELIANA pivotal clinical trial of Kymriah (tisagenlecleucel), the first-ever approved CAR-T cell therapy, in children and young adult patients with relapsed or refractory (r/r) B-cell acute lymphoblastic leukemia (ALL), with a maximum survival follow-up of 5.9 years. For the 79 patients treated with Kymriah in this study, the five-year overall survival (OS) rate was 55% (95% CI, 43-66), while the median event-free survival (EFS) for patients in remission within three months of infusion (n=65) was 43.8 months. These findings demonstrate the curative potential of Kymriah, the only CAR-T cell therapy available for these patients who previously had limited treatment options. These data were presented as an oral presentation during the 2022 European Hematology Association (EHA) Hybrid Congress (Abstract #S112)1.

These data mark a moment of profound hope for children, young adults and their families with relapsed or refractory B-cell ALL, as relapse after five years is rare, said Stephan Grupp, MD, PhD, Section Chief of the Cellular Therapy and Transplant Section, and Inaugural Director of the Susan S. and Stephen P. Kelly Center for Cancer Immunotherapy at Children's Hospital of Philadelphia (CHOP). Since the approval of Kymriah nearly five years ago, we have been able to offer a truly game-changing option to patients who previously faced a five-year survival rate of less than 10 percent.

This long-term follow up of ELIANA demonstrated the potential for Kymriah to transform cancer treatment in pediatric and young adult patients with r/r B-cell ALL, significantly improving outcomes with durable responses and a consistent safety profile in this patient population1:

At Novartis, we strive for cures. With nearly six-year follow-up data in these pediatric and young adults treated for B-cell ALL, we have our strongest evidence yet that one-time treatment with Kymriah has curative potential, said Jeff Legos, Executive Vice President, Global Head of Oncology & Hematology Development. These results strengthen our confidence in CAR-T cell therapies as a truly transformative and paradigm-shifting advance in cancer care, as well as our commitment to continue developing this technology with next-generation platforms.

Additional updates on the Novartis CAR-T program presented at the 2022 EHA Congress include new data from more patients and longer follow-up from the first-in-human dose-escalation trials with YTB323 in adults with r/r diffuse large B-cell lymphoma and PHE885 in adults with r/r multiple myeloma, the first Novartis CAR-T cell therapies developed using the Novartis T-Charge platform2,3,4.

About Kymriah Kymriah is the first-ever FDA-approved CAR-T cell therapy. It is a one-time treatment designed to empower patients immune systems to fight their cancer. Kymriah is currently approved for the treatment of r/r pediatric and young adult (up to and including 25 years of age) acute lymphoblastic leukemia (ALL), r/r adult diffuse large B-cell lymphoma (DLBCL) and r/r adult follicular lymphoma1.

About the ELIANA Trial ELIANA was the first pediatric global CAR-T cell therapy registration trial, examining patients in 25 centers in 11 countries across the US, Canada, Australia, Japan and the EU, including: Austria, Belgium, France, Germany, Italy, Norway and Spain. The trial was an open-label, multicenter, single-arm, global Phase II trial investigating the efficacy and safety of Kymriah in pediatric and young adult patients in r/r B-cell ALL who were primary refractory, chemorefractory, relapsed after, or were not eligible for allogeneic stem cell transplantation (SCT). The primary endpoint was overall remission rate (ORR), defined as best overall response of CR or CR with incomplete blood count recovery (CRi) within 3 months and maintained for 28 day. The secondary endpoints include CR/CRi with undetectable minimal residual disease (MRD), duration of remission, event-free survival, overall survival, cellular kinetics and safety5.

About T-Charge T-Charge is a next-generation CAR-T platform, innovated at the Novartis Institutes for BioMedical Research (NIBR), that will serve as the foundation for various new investigational CAR-T cell therapies in the Novartis pipeline. By implementing the T-Charge platform, we aim to revolutionize CAR-T cell therapy with new products that have the potential to offer patients a higher likelihood of better and more durable responses, improved long-term outcomes and a reduced risk of severe adverse events. The T-Charge platform preserves T cell stemness (T cell ability to self-renew and mature), an important T cell characteristic closely tied to its therapeutic potential, which results in a product containing greater proliferative potential and fewer exhausted T cells. With T-Charge, CAR-T cell expansion occurs primarily within the patients body (in-vivo), eliminating the need for an extended culture time outside of the body (ex-vivo). The T-Charge platform, which implements important process efficiencies, will be rapid, compared with traditional CAR-T, and reliable, through simplified processes and streamlined quality control. Multiple CAR-T therapies, including YTB323 and PHE885, are being developed using the Novartis T-Charge platform.

About Novartis commitment to Oncology Cell Therapy As part of the unique Novartis strategy to pursue four cancer treatment platforms radioligand therapy, targeted therapy, immunotherapy and cell and gene therapy we strive for cures through cell therapies in order to enable more patients to live cancer-free. We will continue to pioneer the science and invest in our manufacturing and supply chain process to further advance transformative innovation.

Novartis was the first pharmaceutical company to significantly invest in pioneering CAR-T research and initiate global CAR-T trials. Kymriah, the first approved CAR-T cell therapy, developed in collaboration with the Perelman School of Medicine at the University of Pennsylvania, is the foundation of the Novartis commitment to CAR-T cell therapy.

We have made strong progress in broadening our delivery of Kymriah, which is currently available for use in at least one indication in 30 countries and at more than 370 certified treatment centers, with clinical and real-world experience from administration to more than6,900 patients. We continue to pioneer in cell therapy, leveraging our vast experience to develop next-generation CAR-T cell therapies. These therapies will utilize our new T-Charge platform being evaluated to expand across hematological malignancies and bring hope for a cure to patients with other cancer types.
