LONDON and GAITHERSBURG, Md., Nov. 10, 2026 (GLOBE NEWSWIRE) -- Autolus Therapeutics plc (Nasdaq: AUTL), a commercial-stage biopharmaceutical company developing, manufacturing and delivering next-generation programmed T cell therapies and candidates, today announces its operational and financial results for the third quarter ended September 30, 2026.

“We delivered another strong quarter of AUCATZYL revenue, primarily driven by growth within existing authorized treatment centers as physicians gain positive experience with the therapy, and supported by real-world data reported through the ROCCA consortium. Importantly, we also continue to improve the gross margin, with strong execution on manufacturing efficiency initiatives,” said Dr. Christian Itin, Chief Executive Officer of Autolus.

Dr. Itin added, “AUCATZYL’s performance in adult r/r B-ALL is a key near-term value driver. Longer term, we believe expanding obe-cel across all stages of ALL and into autoimmune indications offers meaningful opportunities for scalable growth, leveraging its favorable profile and Autolus’ proven manufacturing and commercial capabilities. We look forward to autoimmune program data presentations at upcoming key medical meetings.”

Product and Pipeline Updates:

• AUCATZYL^®
  • Autolus reported net product revenue of $41.2 million for the three months ended September 30, 2026, compared to $21.1 million for the same period the prior year. Net revenues were primarily driven by increasing product demand both within existing treatment centers and expansion into new centers, supplemented by contribution from UK sales.
    
• Obe-cel in pediatric r/r B-ALL
  • The Phase 2 portion of the ongoing CATULUS trial of obe-cel in pediatric patients with relapsed or refractory B-cell precursor ALL (r/r B-ALL) is on track and data are expected to be reported at the end of 2027.

• Obe-cel in lupus
  • Updated data from the ongoing Phase 1 CARLYSLE trial in patients with severe refractory systemic lupus erythematosus (srSLE) will be presented in a poster at the American College of Rheumatology (ACR) Annual Meeting, today, November 10, 2026. These data will include safety and efficacy results with up to 25 months follow-up in adult patients and ≥3 months follow-up in adolescent patients.
  • LUMINA, the pivotal Phase 2 study of obe-cel in patients with refractory lupus nephritis (LN) continues enrolling in five countries and the Company expects to report data in 2028.
  • On September 9, 2026, the U.S. Food and Drug Administration (FDA) granted regenerative medicine advanced therapy (RMAT) designation to obe-cel for the treatment of SLE and LN. RMAT is designed to accelerate the development and regulatory review of regenerative medicine therapies, including cell therapies, intended to treat serious or life-threatening diseases.

• Obe-cel in progressive multiple sclerosis
  • KOL feedback at the ACTRIMS/ECTRIMS meeting in late October emphasized that initial clinical activity and biomarker data seen across CAR T programs are encouraging but will require longer follow up to judge the clinical benefit in progressive MS patients. Considering this feedback, Autolus plans to move the first data presentation to the ECTRIMS Global meeting in October 2027. At that time, the Company expects to have 12 months or more follow-up for the initial 12 patients dosed, and data in up to 24 patients total. Lymphodepletion with both FLu/Cy as well as bendamustine is being evaluated.
    
    
• AUTO8 in Light-Chain Amyloidosis
  • The Phase 1 ALARIC trial evaluating AUTO8 in light-chain amyloidosis is ongoing and initial data are expected to be reported at ASH in December 2026.
    
    

Outlook:
Autolus now expects full-year 2026 AUCATZYL net product revenue to be at or exceeding the upper end of $150 million from the prior guidance.

Based on current operating plans, including anticipated AUCATZYL net revenues and proceeds of the combined first and second tranches totaling $100 million from the Perceptive credit facility, Autolus expects that its current and projected cash, cash equivalents and marketable securities will be sufficient to fund the Company’s operations into Q2 2028.

Summary of Anticipated News Flow:

Financial Results for the Quarter Ended September 30, 2026
Product revenue, net increased to $41.2 million for the three months ended September 30, 2026, compared to $21.1 million the same period in 2025.

Cost of sales decreased to $17.9 million for the three months ended September 30, 2026, compared to $28.6 million the same period in 2025. Gross margin¹ was 57% in the third quarter of 2026, increasing from 55% in the second quarter of 2026, and a negative gross margin in the same period in 2025. The improvement in gross margin over the prior year was primarily driven by a reduction in manufacturing cost per batch, reflecting increased volumes and the ongoing operational efficiency initiatives, and lower inventory reserves and write-offs compared to the same period in the prior year.

Research and development expenses increased to $30.9 million for the three months ended September 30, 2026, compared to $27.9 million in the same period in 2025. This change was primarily due to an increase in clinical manufacturing supply costs driven by clinical development activities, partially offset by a decrease in salaries and other employment-related costs.

Selling, general and administrative expenses decreased to $35.9 million for the three months ended September 30, 2026, compared to $36.3 million in the same period in 2025. This decrease was primarily due to salaries, other employment-related costs and professional fees supporting commercialization activities in the US and UK.

Loss from operations for the three months ended September 30, 2026, was $43.5 million, as compared to $71.6 million for the same period in 2025.

Net loss was $55.1 million for the three months ended September 30, 2026, compared to $79.1 million for the same period in 2025. Basic and diluted net loss per ordinary share for the three months ended September 30, 2026, was $(0.21), compared to basic and diluted net loss per ordinary share of $(0.30) for the same period in 2025.

Cash, cash equivalents and marketable securities at September 30, 2026, totaled $248.4 million, as compared to $201.6 million at June 30, 2026. The increase was primarily driven by net cash inflows from the senior secured note facility from Perceptive Advisors.

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%). 

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 (range: 1 to 23 days) with a median duration of 5 days (range: 1 to 21 days). Sixty-eight percent of patients (51/75) experienced CRS after the first infusion, but prior to the second infusion of AUCATZYL with a median time to onset of 6 days (range: 1 to 10 days). Among patients with CRS, the most common manifestations of CRS included fever (100%), hypotension (35%) and hypoxia (19%). The primary treatment for CRS was tocilizumab (73%; 55/75), with patients also receiving corticosteroids (21%; 16/75).

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 7 days following each infusion. Continue to monitor patients for CRS for at least 2 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). Fifty-five percent of patients (35/64) experienced neurologic toxicities after the first infusion but prior to the second infusion of AUCATZYL with a median time to onset of 6 days (range: 1 to 11 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.

During and following AUCATZYL administration, closely monitor patients for signs and symptoms of Neurologic Toxicity/ICANS. Following treatment with AUCATZYL, monitor patients daily for at least 7 days. Continue to monitor patients for at least 2 weeks following treatment with AUCATZYL. Avoid driving for at least 2 weeks after each infusion. 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. 

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.
