    Novartis today announced longer-term analyses of both ELIANA and JULIET, the pivotal clinical trials of Kymriah (tisagenlecleucel) in children and young adult patients with relapsed or refractory (r/r) acute lymphoblastic leukemia (ALL) and adult patients with r/r diffuse large B-cell lymphoma (DLBCL), respectively. In these analyses, Kymriah continued to demonstrate strong efficacy with durable responses and maintained a consistent and well-characterized safety profile. These data are being presented at the 60th American Society of Hematology (ASH) annual meeting. Additionally, today, the New England Journal of Medicine published online the 14-month results from JULIET, the study led by the Abramson Cancer Center at the University of Pennsylvania[3].

    “After bringing the first CAR-T cell therapy to patients, Novartis is committed to continue our pioneering efforts to reimagine the treatment paradigm for patients with aggressive blood cancer,” said Samit Hirawat, MD, Head, Novartis Oncology Global Drug Development. “These analyses underscore the longer-term durability of response with Kymriah and its consistent safety profile, reinforcing our belief in the potential for CAR-T cell therapy to extend the lives of patients with these advanced B-cell malignancies.”

    In the 24-month follow-up analysis of the ELIANA study in children and young adults with r/r B-cell ALL, Kymriah demonstrated deep and durable responses without subsequent therapy in a significant portion of patients in this population. Among 79 evaluable patients, who were followed for at least three months or discontinued earlier, 82% (95% confidence interval [CI], 72% – 90%) achieved complete response (CR) or CR with incomplete blood count recovery (CRi) within three months of infusion; and among these responding patients, 98% had negative minimal residual disease (MRD-). The relapse-free survival rate was 62% at 24 months; and the median duration of remission (mDOR) and median overall survival (mOS) remained unreached, signifying responses are deep and sustained, and further reinforcing the potential for Kymriah to be a definitive therapy for many patients. The probability of OS was 76% (95% CI, 65% – 85%) at 12 months and 66% (95% CI, 58% – 79%) at 24 months. The safety profile observed in this updated analysis was consistent with previously reported results, with no emergence of new safety signals. Grade 3/4 cytokine release syndrome (CRS) – as defined by the rigorous Penn Grading Scale – occurred in 49% of patients. Within eight weeks of infusion, 13% of patients experienced grade 3 neurological events, with no grade 4 events or cerebral edema[1]. These updated data will be presented in an oral session at the ASH annual meeting (Abstract # 895; Monday, December 3, 4:30 PM PST).
