Autolus Therapeutics Presents Clinical Data Updates at the American Society of Hematology (ASH) Annual Meeting 2024
Autolus Therapeutics (NASDAQ: AUTL) presented clinical data updates at ASH 2024, featuring one oral and three poster presentations about obecabtagene autoleucel (obe-cel) for relapsed/refractory B-cell acute lymphoblastic leukemia (R/R B-ALL).
The FELIX trial demonstrated that obe-cel treatment achieved deep molecular remission in 84% of responders, correlating with improved event-free survival and overall survival. The study showed that lower tumor burden at lymphodepletion yielded the best survival benefits.
Additional findings revealed that bridging therapies were effective with obe-cel, maintaining its expansion and persistence. The treatment showed low incidence of severe adverse events, potentially reducing healthcare resource utilization costs. A new CAR-HEMATOTOX risk score was identified as a useful tool for patient risk stratification.
Autolus Therapeutics (NASDAQ: AUTL) ha presentato aggiornamenti sui dati clinici all'ASH 2024, inclusi un intervento orale e tre presentazioni poster riguardanti obecabtagene autoleucel (obe-cel) per la leucemia linfoblastica acuta a cellule B in recidiva/refrattaria (R/R B-ALL).
Il trial FELIX ha dimostrato che il trattamento con obe-cel ha raggiunto una profonda remissione molecolare nell'84% dei rispondenti, correlata a un miglioramento della sopravvivenza libera da eventi e della sopravvivenza complessiva. Lo studio ha indicato che un carico tumorale più basso durante la linfodeplezione ha fornito i migliori vantaggi in termini di sopravvivenza.
Ulteriori risultati hanno rivelato che le terapie ponte sono risultate efficaci con obe-cel, mantenendo la sua espansione e persistenza. Il trattamento ha mostrato una bassa incidenza di eventi avversi gravi, riducendo potenzialmente i costi di utilizzo delle risorse sanitarie. Un nuovo punteggio di rischio CAR-HEMATOTOX è stato identificato come strumento utile per la stratificazione del rischio dei pazienti.

Insights
The clinical data presented at ASH reveals significant progress for obe-cel in treating relapsed/refractory B-ALL. The 84% deep molecular remission rate is particularly impressive, indicating strong efficacy. Key findings show that lower tumor burden at lymphodepletion correlates with better survival outcomes, while bridging therapy with inotuzumab ozogamicin effectively reduces disease burden pre-treatment.
The safety profile stands out with low rates of severe CRS and ICANS compared to other CAR-T therapies, potentially reducing healthcare costs and improving the risk-benefit ratio. The development of the CAR-HEMATOTOX risk score provides a valuable tool for patient stratification, enabling better prediction of treatment outcomes.
The positive clinical data strengthens obe-cel's commercial potential in the competitive CAR-T therapy market. The demonstrated lower incidence of severe adverse events could translate into significant cost advantages, both for healthcare systems and Autolus's market positioning. The correlation between deep molecular remission and improved survival outcomes provides compelling evidence for payers and could support favorable reimbursement decisions.
For investors, these results reinforce obe-cel's potential as a best-in-class therapy. The real-world data and healthcare resource utilization insights are particularly valuable for commercial success, as they address key concerns about CAR-T therapy costs and implementation.
LONDON, Dec. 09, 2024 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), an early commercial-stage biopharmaceutical company developing next-generation programmed T cell therapies, announces an oral presentation and three poster presentations at the American Society of Hematology (ASH) Annual Meeting, being held from December 7-10, 2024, in San Diego.
“Our oral presentation at ASH this year with data from the FELIX trial demonstrates that obe-cel treatment produces a high incidence of deep molecular remission in r/r adult ALL patients, which correlates with better outcomes and is associated with longer event free survival (EFS) and overall survival (OS),” said Dr. Christian Itin, Chief Executive Officer of Autolus. “We’re also presenting three posters that aim to further our understanding of the use of obe-cel in a real-world context, suggesting the positive clinical outcomes of obe-cel even after effective bridging therapy; the reduced healthcare resource utilization costs associated with lower severity of ICANS and CRS; and how hematotoxicity scores could help identify patients who are at higher risk for hematotoxicity from treatment with obe-cel.”

Summary: Comparable expansion and long-term persistence of obe-cel was observed with all the bridging therapies evaluated, suggesting that long-term persistence of obe-cel is possible irrespective of the bridging therapy and independent of disease burden at lymphodepletion. Bridging therapy with inotuzumab ozogamicin was effective in reducing disease burden prior to lymphodepletion and obe-cel infusion. Reduction in disease burden at lymphodepletion through bridging therapy led to improved event-free survival and overall survival compared to bridging therapy without INO and maintained a tolerable safety profile.

Summary: Grade ≥3 cytokine release syndrome (CRS) and/or immune effector cell-associated neurotoxicity syndrome (ICANS) are associated with increased healthcare resource utilization (HCRU) and costs, but these events were rare in the FELIX study. Costs for adverse events generally increase with event severity. Medication usage and intensive care unit costs were key drivers of CRS and/or ICANS management costs. Obe-cel has the potential to optimize utilization of resources and reduce costs associated with CAR T-cell therapy for patients with R/R B-ALL as a result of the low incidence of Grade ≥3 CRS and/or ICANS.

Summary: The CAR-HEMATOTOX risk score correlated with disease burden in this patient population - patients with high-risk CAR-HEMATOTOX scores had consistently worse outcomes than patients with low-risk CAR-HEMATOTOX scores. Risk-stratification, using pre-lymphodepletion clinical parameters together with disease burden, has the potential to be a useful tool for identifying patients at a high risk for hematotoxicity who may benefit from obe-cel treatment.
