Can Chimeric Antigen Receptor T-Cell Therapy Be a Definitive Treatment for Adult Relapsed/ Refractory B-Cell Acute Lymphoblastic Leukemia Without Stem Cell Transplant? Long-Term Findings and Predictors of Sustained Remission for Obecabtagene Autoleucel
(SOHO 2025)
- P1/2 | " Important factors identified from the UVA included: age (3), response status to first/last LOT, previous allogeneic stem-cell transplantation (SCT), and previous inotuzumab ozogamicin... Obe-cel persistence, low disease burden at lymphodepletion, and obe-cel use in earlier lines were associated with better outcomes and longer survival. These data reinforce that obe-cel persistence is important for long-term survival without additional treatments, suggesting the potential of obe-cel as a definitive treatment. Accepted for presentation at the EHA 2025 Congress (Milan, Italy; June 12-15, 2025)."

(UKKW 2026)
- P1 | "Following lymphodepletion with fludarabine (3×25 mg/m²) and cyclophosphamide (1×1,000 mg/m²), obe-cel was administered as a single starting flat dose of 50×10⁶ (±20%) CAR T-cells... Initial findings from the ongoing CARLYSLE study of obe-cel in srSLE show a manageable safety profile, with no DLTs, ICANS or Grade ≥2 CRS. SLEDAI-2K score reduction and clinical benefit were observed in all patients, including three patients who had a CRR. Despite the short follow up and small number of patients, initial findings are promising; further research is warranted."

OBECABTAGENE AUTOLEUCEL (OBE-CEL) IN RELAPSED/REFRACTORY B-CELL ACUTE LYMPHOBLASTIC LEUKAEMIA (R/R B-ALL): LONG-TERM CLINICAL OUTCOMES IN ADULTS STRATIFIED BY AGE SUBGROUPS OF INTEREST
(EBMT 2026)
- P1/2 | "ORR (complete remission [CR]/CR with incomplete haematological recovery), duration of remission (DoR), event-free survival (EFS), overall survival (OS), safety, and CAR T-cell persistence are reported for patients aged <55/≥55 (groups elected based on published data that showed shorter OS in patients aged ≥55 vs <55 years treated with blinatumomab/inotuzumab ozogamicin), ≥65 (older adults), ≥18–<40 (vulnerable adolescent and young adults population), and ≥26 years (obe-cel UK NICE recommended/EMA conditional approval population)... Obe-cel treatment was associated with a favourable safety profile, high ORR and a 24-month estimated OS probability between 41% and 49% across all investigated age subgroups. These findings indicate that obe-cel is effective and has a positive benefit-risk profile regardless of patient age, including in older adults with R/R B-ALL, who have poorer long-term outcomes/fewer treatment options."

CLINICAL OUTCOMES IN ADULT PATIENTS WITH RELAPSED/REFRACTORY ACUTE LYMPHOBLASTIC LEUKAEMIA (R/R B-ALL) WHO ACHIEVED REMISSION FOLLOWING TREATMENT WITH OBECABTAGENE AUTOLEUCEL (OBE-CEL) IN THE FELIX STUDY
(EBMT 2026)
- P1/2 | "The CRi group were more likely to have received ≥3 lines of prior therapy (42.3% vs 30.1%; prior blinatumomab or inotuzumab ozogamicin: 65.4% vs 43.8%) and had higher median bone marrow blasts at screening (78.5% vs 30.0%) vs the CR group... Most patients with R/R B-ALL who achieved remission following obe-cel achieved CR. Interpretation of long-term outcomes among the CRi group remains limited due to the small number of individuals in this subgroup. A substantial number of patients who responded to obe-cel treatment had a sustained survival benefit, regardless of BOR, with the most pronounced long-term benefit observed in patients who achieved CR."

Geographic Distribution and Racial Disparities of CAR-T cell Therapy Centers in the United States
(TCT-ASTCT-CIBMTR 2026)
- "Product availability varied: tisa-cel was offered at 118 centers, axi-cel and brexu-cel at 160 each, ide-cel and liso- cel at 159 each, cilta-cel at 125, and obe-cel at 53... Although CAR-T centers are distributed nationwide, per-capita access remains limited, particularly in large, minority-dense states. Regions with substantial Hispanic and AA populations demonstrate underrepresentation in CAR-T therapy access relative to their population size, highlighting the need to expand treatment infrastructure to reduce racial and geographic disparities in CAR-T availability. 1."

Mapping Gaps: Geographic and Racial Disparities in CAR-T cell Therapy Access for Multiple Myeloma and B-ALL in the United States
(TCT-ASTCT-CIBMTR 2026)
- "Obe-cel, Tisa-cel and Cilta-cel remained less widely distributed compared to Ide-cel, Axi-cel and Liso-cel, and were absent in multiple states (Obe-cel was not available in 27 states, Tisa-cel in 11 and Cilta-cel in 8). Significant racial inequities exist in CAR-T access for both MM and B-ALL. African Americans have limited availability of anti-BCMA therapies (Ide-cel, Cilta-cel) in high-AA states, while Hispanics face similarly restricted access to B-ALL products (Tisa-cel, Brexu-cel, Obe-cel) in Hispanic-dense regions. Targeted expansion of CAR-T centers is critical to achieving equitable access for these high-burden populations."

Validation of a Multiplexed Quantitative PCR Assay for Obecabtagene Autoleucel CAR T cell Expansion and Persistence Monitoring
(TCT-ASTCT-CIBMTR 2026)
- "Monitoring of CAR T cell persistence can provide important insights into efficacy, durability of response and toxicity. While molecular CAR T cell testing options are commercially available for other anti-CD19 therapies, this has been unavailable to most obe-cel patients outside of clinical trials due to the novel antigen binding domain. This validated obe-cel assay demonstrated excellent performance and will provide rapid and accurate monitoring of CAR T cell dynamics in patients receiving this therapy."

Real-World Cost of Cytokine Release Syndrome (CRS) and Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) Following CAR T-cell Therapy, in US Adults with B-ALL
(TCT-ASTCT-CIBMTR 2026)
- "The frequency of CRS/ICANS observed in this real-world cohort is consistent with those reported in clinical trials and other real-world studies. Our analysis shows the considerable operational burden and financial costs associated with CRS and ICANS, and highlights the substantial impact of high- grade events. Newer CAR T-cell therapies, such as obecabtagene autoleucel which has been associated with low rates of high-grade CRS (2%) and ICANS (7%), could potentially alleviate some of the pressures experienced by healthcare systems and pts/caregivers."

EFFICACY AND SAFETY OUTCOMES OF OBECABTAGENE AUTOLEUCEL (OBE-CEL) STRATIFIED BY AGE IN PATIENTS WITH RELAPSED/REFRACTORY B-CELL ACUTE LYMPHOBLASTIC LEUKEMIA (R/R B-ALL)
(EHA 2025)
- P1/2 | "A higher proportion of pts aged <55 years were Hispanic/Latino (36.7% vs 18.8%), had extramedullary disease at lymphodepletion (29.1% vs 8.3%), and had received prior blinatumomab (53.2% vs 22.9%), and/or prior inotuzumab ozogamicin (35.4% vs 25.0%) vs those aged ≥55 years... Obe-cel treatment was associated with deep and durable remissions resulting in favorable ORR, EFS, and OS with low incidence of Grade ≥3 CRS and ICANS in both age groups. These findings indicate that obe-cel is effective and has a positive benefit and risk profile regardless of pt age, including in older adults with R/R B-ALL, despite few pts receiving consolidative SCT"

(ASCO 2024)
- P1/2 | "Pts received bridging therapy as appropriate and underwent lymphodepletion (fludarabine, 4×30mg/m 2; cyclophosphamide, 2×500mg/m 2 ), followed by obe-cel split dose infusions on Days 1 and 10 based on pre-lymphodepletion leukemic burden at a target dose of 410×10 6 CAR-T cells...At screening, pts' median age was 47 yrs; 42%/31%/44% had received prior blinatumomab/inotuzumab ozogamicin/allogeneic SCT; median bone marrow blast burden was 36% (range: 0−100)... Ongoing CAR-T cell persistency and B-cell aplasia were associated with improved EFS without further consolidation post-obe-cel. At the current follow-up, consolidative SCT for pts in MRD-negative remission post-obe-cel did not improve EFS or OS."
