Novartis Kymriah® demonstrates strong responses in high-risk patients



Novartis announced Kymriah® (tisagenlecleucel) demonstrated strong efficacy in high-risk patients with relapsed or refractory (r/r) follicular lymphoma (FL) based on a subgroup analysis from an approximately 17-month median follow-up of the pivotal Phase II ELARA study1. These results were presented in an oral session at the 63rd American Society of Hematology Annual Meeting & Exposition (ASH) (Abstract #131).To get more novartis news, you can visit shine news official website.

In the subgroup analysis, results showed high rates of durable responses were induced by Kymriah in patients for the majority of high-risk disease subgroups, who typically have a poor prognosis. Complete response rate (CRR), overall response rate (ORR), and durability of response (DOR) were maintained in most patients in the high-risk subgroups, with the exception of those in three of the nine subgroups analyzed: those with progression-of-disease within two years (POD24), high total metabolic tumor volume (TMTV) and patients who had received five or more prior lines of therapy1.

"It's truly exciting to see that after treatment with Kymriah in patients with difficult-to-treat, high-risk follicular lymphoma, patients are experiencing long-lasting responses with a low risk of severe adverse events," said Catherine Thieblemont, MD, PhD, Professor of Hematology in the Paris VII- University, France and Head of the Hemato-Oncology Unit of St-Louis Hospital in Paris.

High and durable responses were seen in the overall population of the ELARA study in which 94 patients were evaluable for efficacy with a median follow-up of approximately 17 months. The CRR was 69% (95% CI, 60-78), ORR was 86% (95% CI, 78-92), 12-month progression-free survival (PFS) was 67% (95% CI, 56-76) and nine-month DOR was 76% (95% CI, 65-84). For patients who had a complete response (CR), 12-month PFS was 86% (95% CI, 74-92) and the estimated DOR rate was 87% (95% CI, 75-93). In the safety analysis (n=97), the safety profile of Kymriah continued to reflect the remarkable results seen in earlier ELARA analyses. Within eight weeks of infusion, 48% of patients experienced cytokine release syndrome (CRS), with no patients experiencing CRS of grade 3 or higher as defined by the Lee scale, 37% had neurological events (3% were greater than or equal to grade 3) and there were no treatment-related deaths1.

A separate analysis of hospitalization and intensive care unit patterns for patients treated in the inpatient and outpatient settings in the ELARA trial suggest Kymriah may reduce healthcare resource utilization for patients with r/r FL treated in the outpatient setting (Abstract #3533). Among patients treated in the outpatient setting (n=17), 35% did not require hospitalization during the first two months of the post-infusion period; those who did had a lower median average length of stay than the patients infused in an inpatient setting (4 days [n=17] vs 12 days [n=80]). Additionally, the mean hospitalization costs in the post-infusion period were substantially lower in the outpatient versus inpatient setting2.

"The ability to administer Kymriah, a potentially definitive treatment, in the outpatient setting may reduce the burden of therapy for patients and their care teams," said Jeff Legos, Executive Vice President, Global Head of Oncology & Hematology Development, Novartis. "The breadth of follicular lymphoma data presented at this year's ASH demonstrate the potential for Kymriah to provide transformative results and a positive impact on health systems overall."

Novartis is committed to bringing the benefits of Kymriah to more patients with advanced blood cancers worldwide, with regulatory submissions for follicular lymphoma in the US and EU complete in October 2021. If approved in this indication, Novartis will look to confirm these results of the ELARA trial and related analyses in the real-world setting.
