Autolus Therapeutics announces that the New England Journal of Medicine has published data from the pivotal Phase 1b/2 FELIX study of obecabtagene autoleucel (obe-cel) in relapsed/refractory (r/r) adult B-cell Acute Lymphoblastic Leukemia (ALL).
AI Summary
Autolus Therapeutics announced that the New England Journal of Medicine has published data from the pivotal Phase 1b/2 FELIX study of obecabtagene autoleucel (obe-cel) in relapsed/refractory adult B-cell Acute Lymphoblastic Leukemia. In the study, about 77% of patients reached complete remission or complete remission with incomplete blood recovery. The data also showed that the treatment had a low incidence of severe immune-related side effects, with only 2.4% experiencing high-grade cytokine release syndrome and 7.1% having severe neurotoxicity. Additionally, nearly half of all treated patients showed event-free survival at 12 months. These promising results suggest that obe-cel could offer a durable and effective option for adults with this aggressive form of leukemia, potentially redefining treatment standards in the relapsed/refractory setting.

Autolus Therapeutics announces a poster presentation at the Society of Hematologic Oncology (SOHO) Annual Meeting being held September 4-7, 2024 in Houston, Texas.
AI Summary
Autolus Therapeutics announced an upcoming poster presentation at the Society of Hematologic Oncology (SOHO) Annual Meeting in Houston, Texas, scheduled for September 4-7, 2024. The presentation will focus on their investigational CAR T-cell therapy, obe-cel, for treating relapsed/refractory Adult B-Cell Acute Lymphoblastic Leukemia (r/r B-ALL) using a tumor burden (TB)-guided dosing strategy.
The study, part of the FELIX Phase 1b/2 trial, highlights that administering obe-cel in two doses—regardless of a patient’s TB before lymphodepletion—results in high CAR T-cell expansion and a strong overall remission rate. The poster, entitled "Obecabtagene autoleucel (obe-cel) for Relapsed/Refractory Adult B-Cell Acute Lymphoblastic Leukemia (r/r B-ALL): Impact of CAR T and TB-Guided Dosing," will be presented by Dr. Elias Jabbour at 6:15 pm on September 4, in Hall B3 (Poster Number ALL-502).

Autolus Therapeutics announces three abstracts to be presented at the European Hematology Association (EHA) Congress, June 13-16, 2024.
AI Summary
Autolus Therapeutics has announced that it will present three abstracts at the upcoming European Hematology Association (EHA) Congress, scheduled for June 13-16, 2024. One abstract will focus on results from the FELIX study, which examined the use of obe-cel in adult patients with relapsed/refractory acute lymphoblastic leukemia. The data, with a median follow-up of 21.5 months, indicate a 78% overall response rate, with roughly 40% of patients maintaining remission without further treatment. The findings suggest that obe-cel may lead to a durable response as a single agent, with both event-free and overall survival showing promising stabilization at around 40%. The other abstracts will explore the impact of inotuzumab-containing bridging therapy and compare methods for measuring CAR T-cell kinetics, further supporting the potential of CAR T treatments in blood cancers.

Autolus Therapeutics announces longer-term follow-up and additional data analysis from the pivotal Phase 1b/2 FELIX study of obecabtagene autoleucel (obe-cel) in relapsed/refractory (r/r) adult B-cell Acute Lymphoblastic Leukemia (ALL), being presented at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting, (May 31 – June 4, 2024, Chicago).
AI Summary
Autolus Therapeutics announced new longer-term follow-up results and additional analysis from its pivotal Phase 1b/2 FELIX study for obecabtagene autoleucel (obe-cel) in adults with relapsed/refractory B-cell Acute Lymphoblastic Leukemia. At a median follow-up of 21 months, the data showed that 40% of patients remained in ongoing remission without needing a stem cell transplant or additional therapy. The study results indicate that the durability of responses may lead to a long-term plateau in survival outcomes. Additionally, ongoing CAR T cell persistence was linked to improved event-free survival, further supporting the potential of obe-cel as an effective standalone therapy. These findings, which build on earlier Phase 1 ALLCAR19 data, will be presented at the 2024 ASCO Annual Meeting in Chicago from May 31 through June 4, 2024.
