LONDON, May 8, 2025 -- 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 first quarter ended March 31, 2025.

 

"We had a great first quarter of launch and are highly encouraged by physician
enthusiasm for AUCATZYL in the U.S. We believe this speaks to the product
profile and significant unmet need for patients," said Dr. Christian Itin,
Chief Executive Officer of Autolus. "Building on that momentum in the U.S., we
recently obtained marketing authorization from the UK's MHRA, and we are
working in collaboration with National Institute for Health and Care
Excellence (NICE) to bring this much-needed therapy to patients in the UK. Our
goal to expand into new markets is underpinned by our proprietary
manufacturing and commercial infrastructure which has positioned us for strong
execution."

 

"In the second quarter we are planning to share longer-term follow-up data
from the FELIX study, and in the second half of the year we plan to announce
data from the pediatric PY1 trial. Building on strong data with obe-cel in r/r
B-ALL, we are looking beyond ALL and recently highlighted at an R&D
investor event our potential for value creation driven by obe-cel in
autoimmune diseases, including lupus nephritis (LN) and multiple sclerosis
(MS). Supporting our plans to pursue LN, we reported encouraging early
clinical data that show obe-cel's potential to treat advanced and relapsed
lupus patients. We have aligned with the U.S. Food and Drug Administration
(FDA) on a compact Phase 2 trial design and potential registrational path to
approval and we look forward to dosing the first patient in the Phase 2 trial
before year-end."

 

Key updates and anticipated milestones:

 

·    AUCATZYL® Launch

o Autolus reported Q1 2025 net product sales of $9.0 million.

o The Company has 39 centers fully activated in the U.S. as of May 7, 2025.

o Patient access to AUCATZYL continues to increase, with coverage secured for
approximately 90% of total U.S. medical lives.

o  On April 1, 2025, the Centers for Medicare and Medicaid Services (CMS)
included AUCATZYL in their published Healthcare Common Procedure Coding System
(HCPCS) coding determinations and Hospital Outpatient Prospective Payment
System (OPPS) payment rates, formalizing reimbursement for patients on
government programs. The CMS policy splits the therapeutic dose of AUCATZYL
into two administrations for coding and billing purposes. The Company is
working with the treatment centers on implementing the coding and payment
policy from CMS and is assessing any potential impact on the timing of revenue
recognition.

o On April 25, 2025, the UK Medicines and Healthcare products Regulatory
Agency (MHRA) granted conditional marketing authorization for
AUCATZYL(®) (obecabtagene autoleucel) for the treatment of adult patients
with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (r/r
B-ALL). The Company will work with the National Institute for Health and Care
Excellence (NICE) on patient access to therapy and a meeting is planned for
May 2025.

o Obe-cel is under regulatory review in the EU and the Company expects to
receive notification of approval status from the European Medicines Agency
(EMA) in the second half of 2025.

 

·    Obe-cel in lupus nephritis (LN)

o 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.  Out of six patients in the cohort, three patients had
complete renal response, all by month three. Complement normalized in all
patients by month one. Rash, alopecia and mucosal ulcers resolved by month
three and arthritis resolved by month one in all patients. Data show high peak
expansion and deep B cell aplasia consistent with known obe-cel
characteristics in oncology indications. No dose limiting toxicities (DLTs) or
immune effector cell-associated neurotoxicity syndrome (ICANS) were observed
in the study to date. Grade one cytokine release syndrome (CRS) was observed
in three out of six patients. Hypertension, a typical sign of advanced lupus
nephritis, pre-existed in three patients. On study, five of six patients
experienced a transient hypertension, including Grade 3, well managed by
anti-hypertensive agents.

o The Company has aligned with U.S. Food and Drug Administration (FDA) on the
Phase 2 trial design and potential registrational path to approval and
anticipates dosing the first patient in a Phase 2 trial before the end of
2025.

o Full data with longer term follow-up from the Phase 1 CARLYSLE clinical
trial is targeted for presentation at a medical conference in the second half
of 2025.

·     Obe-cel in progressive MS

o Autolus plans to advance obe-cel into clinical development in progressive
MS. The Company expects 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

o Autolus' translational programs with UCL continue to fuel its early-stage
pipeline, providing a cost-efficient path to development.

Financial Results for the Quarter Ended March 31, 2025

 

Product revenue, net for the three months ended March 31, 2025 was $9.0
million.

 

Cost of sales for the three months ended March 31, 2025 totaled $18.0 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 $30.7 million to $26.7
million for the three months ended March 31, 2025, compared to the same period
in 2024. This change was primarily due to commercial manufacturing related
employee and infrastructure cost shifting to cost of sales and inventory,
partially offset by an increase in obe-cel clinical trial and supply costs.

 

Selling, general and administrative expenses increased from $18.2 million to
$29.5 million for the three months ended March 31, 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 U.S.
commercialization activities.

 

Loss from operations for the three months ended March 31, 2025 was $65.2
million, as compared to $38.8 million for the same period in 2024.

 

Net loss was $70.2 million for the three months ended March 31, 2025, compared
to $52.7 million for the same period in 2024. Basic and diluted net loss per
ordinary share for the three months ended March 31, 2025, totaled $(0.26),
compared to basic and diluted net loss per ordinary share of $(0.24) for the
same period in 2024.

 

Cash, cash equivalents and marketable securities at March 31, 2025, totaled
$516.6 million, as compared to $588.0 million at December 31, 2024. The
decrease was primarily driven by net cash used in operating and investing
activities and impacted by a delayed cash receipt of approximately $20 million
in R&D tax credit expected from the UK HMRC.

 

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.

About obe-cel FELIX clinical trial

Autolus' Phase 1b/2 clinical trial of obe-cel enrolled adult patients with r/r
B-precursor ALL. The trial had a Phase 1b component prior to proceeding to the
single arm, Phase 2 clinical trial. The primary endpoint in the pivotal cohort
was overall response rate, and the secondary endpoints included duration of

About AUCATZYL® (obecabtagene autoleucel, obe-cel, AUTO1)

AUCATZYL is a B-lymphocyte antigen CD19 (CD19) chimeric antigen receptor (CAR)
T cell therapy designed to overcome the limitations in clinical activity and
safety compared to current CD19 CAR T cell therapies. AUCATZYL is designed
with a fast target binding off-rate to minimize excessive activation of the
programmed T cells. AUCATZYL was approved by the FDA for the treatment of
adult patients with relapsed or refractory B-cell precursor acute
lymphoblastic leukemia on November 8, 2024, and was granted marketing
authorization by the MHRA in the UK on April 25, 2025. In the EU, a regulatory
submission to the EMA for AUCATZYL was accepted in April 2024.

 

INDICATION

AUCATZYL(®) is a CD19-directed genetically modified autologous T cell
immunotherapy indicated for the treatment of adult patients with relapsed or
refractory B-cell precursor acute lymphoblastic leukemia (ALL).

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 × 10(6) CD19 CAR-positive viable T
cells (range: 10 to 480 × 10(6) CD19 CAR-positive viable T cells with 90% of
patients receiving the recommended dose of 410 × 10(6) +/- 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.
