LONDON and GAITHERSBURG, Md., Aug. 12, 2025 (GLOBE NEWSWIRE) — Autolus Therapeutics plc (Nasdaq: AUTL), an early commercial-stage biopharmaceutical company developing, manufacturing and delivering next-generation programmed T cell therapies, announces its operational and financial results for the second quarter ended June 30, 2025.

“We are encouraged by AUCATZYL’s early launch performance in the U.S., driven by physician enthusiasm for the product profile, unmet need for r/r B-All patients and favorable market access and reimbursement – supported by strong execution on manufacturing and product delivery,” said Dr. Christian Itin, Chief Executive Officer of Autolus. “With recent approvals in the EU and UK our focus shifts to market access on a country-by-country basis. In addition to commercial progress in the adult setting, we look forward to reporting clinical data from the pediatric PY1 trial of obe-cel in ALL in the second half of the year and believe there is additional growth opportunity in pediatric ALL.”

“Beyond ALL, we believe obe-cel has ‘pipeline-in-a-product’ potential and could deliver improved outcomes in autoimmune disease. We are excited about the recently reported preliminary data from the Phase 1 CARLYSLE study in systemic lupus erythematous (SLE). We look forward to reporting additional Phase 1 data in SLE patients at a medical conference later this year; dosing the first patient in our planned Phase 2 pivotal trial in LN and starting a Phase 1 trial in progressive multiple sclerosis (MS) by year-end.”

Key updates and anticipated milestones:

• AUCATZYL® Launch
  • Autolus reported Q2 2025 net product sales of $20.9 million.
  • The Company has 46 centers fully activated in the U.S. as of August 12, 2025. 
  • Patient access to AUCATZYL continues to increase, with coverage secured for greater than 90% of total U.S. medical lives.
  • On April 25, 2025, the UK Medicines and Healthcare products Regulatory Agency (MHRA) granted conditional marketing authorization for AUCATZYL for the treatment of adult patients age 18+ with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (r/r B-ALL). Following an initial review and in line with prior practice for CAR T therapies the National Institute for Health and Care Excellence (NICE) issued a preliminary Appraisal Consultation Decision (ACD) recommending against funding for AUCATZYL. Autolus plans to respond to NICE’s questions and will continue to work towards a pathway for patient access to therapy in the UK.
  • On July 17, 2025, the European Commission (EC) granted conditional marketing authorization for AUCATZYL in adult patients (age 26 and older) with r/r B-ALL. Evaluation of potential pricing and feasibility of market entry opportunities in certain EU countries is ongoing; however, at this time launch in Germany is on hold and the Company does not anticipate any EU sales of AUCATZYL in 2025 and 2026.

• Obe-cel data in r/r B-ALL
  • Autolus presented updated long-term data from the FELIX study in adult patients with r/r B-ALL in an oral presentation at the 2025 European Hematology Association (EHA) Congress in June. For patients with a response, the updated median duration of response (mDOR) is now 42.5 months. At the updated median follow up of 32.8 months, 38.4% of responders were in ongoing remission without consolidative stem cell therapy or other therapies (versus the previously reported 40% at a median follow-up of 21.5 months). The 24-month probability of Event Free Survival was 43%, and the Overall Survival was 46%, with a further consolidating long-term plateau observed. No new safety signals or Grade ≥3 secondary malignancies were observed at the extended follow-up. These results suggest that obe-cel may be a durable treatment option for some patients with r/r B-ALL.
• Obe-cel in lupus nephritis (LN)
  • Preliminary data from the Phase 1 dose confirmation clinical trial (CARLYSLE) in refractory systemic lupus erythematosus (SLE) patients were reported on April 23, 2025, and support progressing into a planned Phase 2 pivotal study.
  • The Company has aligned with the U.S. Food and Drug Administration (FDA) on the Phase 2 trial design and potential registrational path to approval and continues to anticipate dosing the first patient in a Phase 2 clinical trial before the end of 2025. 
  • Data with longer term follow-up from the Phase 1 CARLYSLE clinical trial is on track for presentation at a medical conference in the second half of 2025. 
•  Obe-cel in progressive MS 
  • Autolus plans to advance obe-cel into initial clinical development in progressive MS. The Company continues to expect to dose its first patient in a Phase 1 dose escalation study by year-end 2025.  
• Early-stage pipeline programs and collaborations support longer-term growth
  • Autolus’ translational programs with UCL continue to fuel its early-stage pipeline, providing a cost-efficient path to development.

Summary of Anticipated News Flow: 

ALL: adult lymphoblastic leukemia
SLE: systemic lupus erythematosus
LN: lupus nephritis
MS: multiple sclerosis
ALA: light-chain amyloidosis

Financial Results for the Quarter Ended June 30, 2025

Product revenue, net for the three months ended June 30, 2025 was $20.9 million.

Cost of sales for the three months ended June 30, 2025 totaled $24.4 million. This amount includes the cost of all commercial product delivered to the authorized treatment centers, including product delivered but not yet recorded as product revenue which is captured as deferred revenue. Additionally, cost of sales includes any cancelled orders in the period, patient access program product, and 3^rd party royalties for certain technology licenses.  

Research and development expenses decreased from $36.6 million to $27.4 million for the three months ended June 30, 2025, compared to the same period in 2024. This change was primarily due to commercial manufacturing-related employee and infrastructure costs shifting to cost of sales and inventory.

Selling, general and administrative expenses increased from $21.9 million to $30.3 million for the three months ended June 30, 2025, compared to the same period in 2024. This increase was primarily due to salaries and other employment-related costs, driven by increased headcount supporting commercialization activities.

Loss from operations for the three months ended June 30, 2025 was $61.2 million, as compared to $58.9 million for the same period in 2024.

Net loss was $47.9 million for the three months ended June 30, 2025, compared to $58.3 million for the same period in 2024. Basic and diluted net loss per ordinary share for the three months ended June 30, 2025, totaled $(0.18), compared to basic and diluted net loss per ordinary share of $(0.22) for the same period in 2024.

Cash, cash equivalents and marketable securities at June 30, 2025, totalled $454.3 million, as compared to $588.0 million at December 31, 2024. The decrease was primarily driven by net cash used in operating activities and impacted by a delayed cash receipt of approximately $21.7 million in R&D tax credit expected from the UK HMRC, which was expected to be received during the six months ended June 30, 2025. 

Autolus estimates that, with its current cash and cash equivalents and marketable securities, the Company is well capitalized to drive the launch and commercialization of obe-cel in r/r B-ALL and to obtain data in the LN pivotal trial and MS Phase 1 trial.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Cytokine Release Syndrome (CRS)
Cytokine Release Syndrome (CRS) occurred following treatment with AUCATZYL. CRS was reported in 75% (75/100) of patients including Grade 3 CRS in 3% of patients. The median time to onset of CRS was 8 days following the first infusion (range: 1 to 23 days) with a median duration of 5 days (range: 1 to 21 days). The most common manifestations of CRS included fever (100%), hypotension (35%), and hypoxia (19%).

Prior to administering AUCATZYL, ensure that healthcare providers have immediate access to medications and resuscitative equipment to manage CRS. During and following treatment with AUCATZYL, closely monitor patients for signs and symptoms of CRS daily for at least 14 days at the healthcare facility following the first infusion. Continue to monitor patients for CRS for at least 4 weeks following each infusion with AUCATZYL. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, immediately evaluate the patient for hospitalization and institute treatment with supportive care based on severity and consider further management per current practice guidelines.

Neurologic Toxicities
Neurologic toxicities including Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS), which were fatal or life-threatening, occurred following treatment with AUCATZYL. Neurologic toxicities were reported in 64% (64/100) of patients, including Grade ≥ 3 in 12% of patients. The median time to onset of neurologic toxicities was 10 days (range: 1 to 246 days) with a median duration of 13 days (range: 1 to 904 days). Among patients with neurologic toxicities, the most common symptoms (> 5%) included ICANS (38%), headache (34%), encephalopathy (33%), dizziness (22%), tremor (13%), anxiety (9%), insomnia (9%), and delirium (8%).

Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS)
ICANS events occurred in 24% (24/100) of patients, including Grade ≥ 3 in 7% (7/100) of patients. Of the 24 patients who experienced ICANS, 33% (8/24) experienced an onset after the first infusion, but prior to the second infusion of AUCATZYL.
The median time to onset for ICANS events after the first infusion was 8 days (range: 1 to 10 days) and 6.5 days (range: 2 to 22 days) after the second infusion, with a median duration of 8.5 days (range: 1 to 53 days).

Eighty-eight percent (21/24) of patients received treatment for ICANS. All treated patients received high-dose corticosteroids and 42% (10/24) of patients received anti-epileptics prophylactically. Prior to administering AUCATZYL, ensure that healthcare providers have immediate access to medications and resuscitative equipment to manage ICANS.

Counsel patients to seek medical attention should signs or symptoms of neurologic toxicity/ ICANS occur. At the first sign of Neurologic Toxicity /ICANS, immediately evaluate patients for hospitalization and institute treatment with supportive care based on severity and consider further management per current practice guidelines.

Effect on Ability to Drive and Use Machines
Due to the potential for neurologic events, including altered mental status or seizures, patients receiving AUCATZYL are at risk for altered or decreased consciousness or coordination in the eight weeks following AUCATZYL infusion or until resolution of the neurological event by the treating physician. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period.

Prolonged Cytopenias
Patients may exhibit cytopenias including anemia, neutropenia, and thrombocytopenia for several weeks after treatment with lymphodepleting chemotherapy and AUCATZYL. In patients who were responders to AUCATZYL, Grade ≥ 3 cytopenias that persisted beyond Day 30 following AUCATZYL infusion were observed in 71% (29/41) of patients and included neutropenia (66%, 27/41) and thrombocytopenia (54%, 22/41). Grade 3 or higher cytopenias that persisted beyond Day 60 following AUCATZYL infusion was observed in 27% (11/41) of patients and included neutropenia (17%, 7/41) and thrombocytopenia (15%, 6/41). Monitor blood counts after AUCATZYL infusion.

Infections
Severe, including life-threatening and fatal infections occurred in patients after AUCATZYL infusion. Non-COVID-19 infections of all grades occurred in 67% (67/100) of patients. Grade 3 or higher non-COVID-19 infections occurred in 41% (41/100) of patients. AUCATZYL should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after AUCATZYL infusion and treat appropriately. Administer prophylactic antimicrobials according to local guidelines.
Grade 3 or higher febrile neutropenia was observed in 26% (26/100) of patients after AUCATZYL infusion and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care as medically indicated.
Viral reactivation, potentially severe or life-threatening, can occur in patients treated with drugs directed against B cells. There is no experience with manufacturing AUCATZYL for patients with a positive test for human immunodeficiency virus (HIV) or with active hepatitis B virus (HBV) or active hepatitis C virus (HCV). Perform screening for HBV, HCV and HIV in accordance with clinical guidelines before collection of cells for manufacturing.

Hypogammaglobulinemia
Hypogammaglobulinemia and B-cell aplasia can occur in patients after AUCATZYL infusion. Hypogammaglobulinemia was reported in 10% (10/100) of patients treated with AUCATZYL including Grade 3 events in 2 patients (2%).
Immunoglobulin levels should be monitored after treatment with AUCATZYL and managed per institutional guidelines including infection precautions, antibiotic or antiviral prophylaxis, and immunoglobulin replacement.
The safety of immunization with live viral vaccines during or following treatment with AUCATZYL has not been studied. Vaccination with live viral vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy treatment, during AUCATZYL treatment, and until immune recovery following treatment with AUCATZYL.

Hemophagocytic Lymphohistiocytosis/Macrophage Activation Syndrome (HLH/MAS)
HLH/MAS including fatal and life-threatening reactions occurred after treatment with AUCATZYL. HLH/MAS was reported in 2% (2/100) of patients and included Grade 3 and Grade 4 events with a time of onset at Day 22 and Day 41, respectively. One patient experienced a concurrent ICANS events after AUCATZYL infusion and died due to sepsis with ongoing HLH/MAS that had not resolved. Administer treatment for HLH/MAS according to institutional standards.

Hypersensitivity Reactions
Serious hypersensitivity reactions, including anaphylaxis, may occur due to dimethyl sulfoxide (DMSO), an excipient used in AUCATZYL. Observe patients for hypersensitivity reactions during and after AUCATZYL infusion.
Secondary Malignancies
Patients treated with AUCATZYL may develop secondary malignancies. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes. Monitor lifelong for secondary malignancies. In the event that a secondary malignancy occurs, contact Autolus at 1-855-288-5227 for reporting and to obtain instructions on the collection of patient samples for testing.

Adverse Reactions
The safety of AUCATZYL was evaluated in the FELIX study in which 100 patients with relapsed or refractory B-cell acute lymphoblastic leukemia (B-ALL) received AUCATZYL at a median dose of 410 × 10⁶ CD19 CAR-positive viable T cells (range: 10 to 480 × 10⁶ CD19 CAR-positive viable T cells with 90% of patients receiving the recommended dose of 410 × 10⁶ +/- 25%).

The most common serious adverse reactions of any Grade (incidence ≥ 2%) included infections-pathogen unspecified, febrile neutropenia, ICANS, CRS, fever, bacterial infectious disorders, encephalopathy, fungal infections, hemorrhage, respiratory failure, hypotension, ascites, HLH/MAS, thrombosis and hypoxia. Nine patients (9%) experienced fatal adverse reactions which included infections (sepsis, pneumonia, peritonitis), ascites, pulmonary embolism, acute respiratory distress syndrome, HLH/MAS and ICANS. Of the 9 patients, five patients who died from infections had pre-existing and ongoing neutropenia prior to receiving bridging therapy, lymphodepletion chemotherapy treatment and/or AUCATZYL.
