This application is based on the results of the Phase 3 LITESPARK-011 trial evaluating the dual regimen of LENVIMA plus WELIREG for the treatment of patients with advanced renal cell carcinoma (RCC) whose disease progressed on or after treatment with anti-programmed death receptor-1 (PD-1)/ programmed death-ligand 1 (PD-L1) therapy. The data from this trial were presented at the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Genitourinary (GU) Cancers Symposium in February 2026. At a pre-specified interim analysis with a median follow-up of 29.0 months (range, 19.3-49.2), the LENVIMA plus WELIREG combination therapy demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS), one of the primary endpoints, reducing the risk of disease progression or death by 30% (HR=0.70 [95% CI, 0.59-0.84]; p=0.00007) compared to cabozantinib. The safety profile of this combination was consistent with those reported for each agent administered as monotherapy, and no new safety signals were identified.

In 2022, approximately 435,000 people worldwide were newly diagnosed with kidney cancer, and about 156,000 people died from the disease. 1 In Japan, it is estimated that roughly 21,000 people were newly diagnosed and about 7,000 died in 2022.2 RCC accounts for approximately 85% of kidney cancers3, and the five-year survival rates for patients with stage III and IV RCC have been reported as 63%–78% and 27%–28%4, respectively, indicating that the disease still has a high unmet medical needs.

LENVIMA is approved in combination with KEYTRUDA (pembrolizumab) in Japan for the first-line treatment of unresectable or metastatic RCC. WELIREG is approved in Japan for the treatment of unresectable or metastatic RCC that has progressed following cancer chemotherapy. Additionally, supplemental New Drug Applications (sNDA) for the LENVIMA and WELIREG combination therapy for the treatment of adult patients with advanced RCC with a clear cell component following a PD-1 or PDL1 inhibitor has been accepted by the U.S. Food and Drug Administration (FDA), with a PDUFA (Prescription Drug User Fee Act) target action date set for October 4, 2026.

Eisai and MSD have been collaborating through the provision of information on LENVIMA in Japan since October 2018, and will work together to expedite the maximization of contribution to patients with cancer.

About LENVIMA (lenvatinib)

LENVIMA, discovered and developed by Eisai, is an orally available multiple receptor tyrosine kinase inhibitor that inhibits the kinase activities of vascular endothelial growth factor (VEGF) receptors VEGFR1 (FLT1), VEGFR2 (KDR), and VEGFR3 (FLT4). LENVIMA inhibits other kinases that have been implicated in pathogenic angiogenesis, tumor growth, and cancer progression in addition to their normal cellular functions, including fibroblast growth factor (FGF) receptors FGFR1- 4, the platelet derived growth factor receptor alpha (PDGFRα), KIT, and RET. In syngeneic mouse tumor models, LENVIMA decreased tumor-associated macrophages, increased activated cytotoxic T cells, and demonstrated greater antitumor activity in combination with an anti-PD-1 monoclonal antibody compared to either treatment alone. LENVIMA has been approved for the indications below.

About WELIREG (belzutifan)

WELIREG, Merck & Co., Inc., Rahway, NJ, USA’s, known as MSD outside of the United States and Canada, first-in-class hypoxia-inducible factor 2 alpha (HIF-2α) inhibitor, is an orally administered small-molecule designed to reduce transcription and expression of HIF-2α target genes associated with cellular proliferation, angiogenesis and tumor growth. By inhibiting HIF-2α signaling, WELIREG aims to disrupt key pathways certain tumors may use to adapt to low-oxygen conditions, including those that help promote abnormal blood vessel formation and support tumor survival. WELIREG has demonstrated antitumor activity in certain von Hippel-Lindau (VHL) diseaseassociated tumors, renal cell carcinoma and in pheochromocytoma or paraganglioma. As part of a broader clinical program, Merck & Co., Inc., Rahway, NJ, USA continues to research WELIREG monotherapy and combination approaches for people with genitourinary, breast and gynecologic cancers across a range of treatment settings to further define where HIF-2α inhibition may provide clinical benefit and to better understand which patients are most likely to respond. WELIREG has been approved in Japan for the treatment of certain von Hippel–Lindau (VHL) disease–associated tumors, as well as for unresectable or metastatic renal cell carcinoma that has progressed after chemotherapy.

LITESPARK-011 Results

Data from LITESPARK-011 (ClinicalTrials.gov, NCT04586231) were presented at the ASCO (Free ASCO Whitepaper) GU Symposium held in February 2026. LITESPARK-011 is a randomized, open-label Phase 3 trial (ClinicalTrials.gov, NCT04586231) evaluating WELIREG in combination with LENVIMA compared to cabozantinib for the treatment of patients with advanced clear cell RCC that has progressed on or after anti-PD-1/L1 therapy. The dual primary endpoints are progression-free survival (PFS) per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) as assessed by blinded independent central review (BICR), and overall survival (OS). Secondary endpoints include objective response rate (ORR) per RECIST v1.1 as assessed by BICR, duration of response (DOR) per RECIST v1.1 as assessed by BICR, and safety. The trial enrolled 747 patients who were randomized to receive WELIREG (120 mg orally once daily) plus LENVIMA (20 mg orally once daily) or cabozantinib (60 mg orally once daily).

At a pre-specified second interim analysis with a median follow-up of 29.0 months (range, 19.3- 49.2), WELIREG plus LENVIMA demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of PFS, reducing the risk of disease progression or death by 30% (HR=0.70 [95% CI, 0.59-0.84]; p=0.00007) compared to cabozantinib. For WELIREG plus LENVIMA, the median PFS was 14.8 months (95% CI, 11.2-16.6) versus 10.7 months (95% CI, 9.2-11.1) for cabozantinib. A trend toward improvement in overall survival (OS), the trial’s other primary endpoint, was also observed for WELIREG plus LENVIMA (HR=0.85 [95% CI, 0.68-1.05]; p=0.06075). The median OS was 34.9 months (95% CI, 27.5-NR) for WELIREG plus LENVIMA versus 27.6 months (95% CI, 24.0-31.4) for cabozantinib. The trial is continuing, and OS will be evaluated at a subsequent analysis per the clinical trial protocol. Regarding secondary endpoints, at the first interim analysis with a median follow-up of 19.6 months (range, 9.9-39.8), WELIREG plus LENVIMA met ORR, demonstrating a statistically significant improvement compared to cabozantinib. A confirmed ORR of 52.6% (95% CI, 47.3-57.7) was observed for WELIREG plus LENVIMA versus 39.6% (95% CI, 34.6-44.8) for cabozantinib. At the second interim analysis with a median follow-up of 29.0 months, the median DOR was 23.0 months (95% CI, 2.0-44.3+) for WELIREG plus LENVIMA versus 12.3 months (95% CI, 1.8+-35.9+) for cabozantinib. WELIREG plus LENVIMA was administered to 370 patients and cabozantinib was administered to 371 patients. Grade ≥3 treatment-related adverse events (TRAEs) occurred in 71.6% of patients receiving WELIREG plus LENVIMA versus 65.8% of patients receiving cabozantinib. Adverse events led to treatment discontinuation in 11.1% of patients receiving WELIREG plus LENVIMA and in 11.3% of patients receiving cabozantinib, respectively. Serious adverse events were observed in 51.6% of patients receiving WELIREG plus LENVIMA versus 43.9% of patients receiving cabozantinib, and AEs led to death in 5.4% of patients (two were treatment-related: thrombotic microangiopathy [n=1] and pneumonitis [n=1]) versus 3.2% (one was treatment-related: hemoptysis [n=1]) of patients, respectively.

"Autolus had a strong first year of launch of AUCATZYL in the US building a market leading position in adult patients with relapsed or refractory B-ALL and demonstrating strong commercial execution, including reliable, high-quality product delivery with consistent turn-around time. Parallel to the launch, the ROCCA consortium collected real world data from approximately 60% of the commercial patients treated with AUCATZYL. Recently reported data confirm a high level of clinical activity without inducing high grade CRS and only 3% of patients experiencing high grade ICANS. We expect this positive customer experience will be a key driver for the future growth of AUCATZYL," said Dr. Christian Itin, Chief Executive Officer of Autolus.

Dr. Itin continued, "Our focus in 2026 will be on driving adoption of AUCATZYL in the US, launching in the UK and expanding the utility of obe-cel in additional indications while leveraging our established commercial and manufacturing capabilities. Based on regulatory feedback we are executing two compact pivotal studies: CATULUS in pediatric r/r B-ALL and LUMINA in severe lupus nephritis patients. In addition, we are exploring the utility of obe-cel in progressive MS patients in the Phase 1 BOBCAT study. Clinical data updates are planned for long-term follow up of the Phase 1 CARLYSLE data in severe SLE patients, initial clinical experience in light chain amyloidosis from the ALARIC study with AUTO8 and initial data from the BOBCAT study by the end of 2026."

Product and Pipeline Updates:

AUCATZYL Launch
Autolus reported net product revenue of $23.3 million* for the three months ended December 31, 2025, and $74.3 million* for the year ended December 31, 2025, driven by U.S. sales.
Following a successful National Institute for Health and Care Excellence (NICE) evaluation, AUCATZYL launched in the UK in January 2026 and is now available under routine commissioning.
Data from the ROCCA (Real-World Outcomes Collaborative for CAR T in Adult ALL) consortium database evaluating patient characteristics, toxicity and response after real-world administration of AUCATZYL was presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in December 2025 and the TANDEM meeting in February 2026. Real-world data show consistency in both safety and efficacy compared to the FELIX clinical trial that was the basis for regulatory approvals. The ROCCA Consortium registry covers approximately 60% of U.S. commercial patients at a data cutoff of January 5, 2026.
Obe-cel data in pediatric r/r B-ALL
Preliminary data from the CATULUS Phase 1 trial of obe-cel in pediatric relapsed or refractory (r/r) B-ALL patients were presented at the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in December 2025. Obe-cel demonstrated high remission rates in pediatric patients with high-risk r/r B-ALL with overall response rate (ORR) of 95.5%. Low rates of high-grade cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) were observed, consistent with obe-cel’s adult safety profile. The Phase 2 portion of the trial is underway and Autolus expects to report data at the end of 2027.
In October 2025, the U.S. Food and Drug Administration (FDA) granted regenerative medicine advanced therapy (RMAT) designation to obe-cel for the treatment of pediatric patients with r/r B-ALL. The RMAT designation is a program created under the 21st Century Cures Act to accelerate development and regulatory review of regenerative medicine therapies, including cell therapies, intended to treat serious or life-threatening diseases.

Obe-cel in lupus nephritis

Data from the ongoing Phase 1 CARLYSLE trial in patients with severe refractory systemic lupus erythematosus (srSLE) were reported at the American College of Rheumatology (ACR) Convergence 2025 and the American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting. All patients show deep B-cell depletion after infusion, suggesting an immune reset. No ICANS or high-grade CRS were observed in the nine patients evaluable for safety.
Data support progressing obe-cel as a treatment for LN and 50 million cells was selected as the recommended Phase 2 dose.
Autolus has previously aligned with the US Food and Drug Administration (FDA) on a Phase 2 trial design in LN and potential registrational path to approval. The LUMINA trial is now enrolling and the Company expects to report data in 2028.
Obe-cel in progressive multiple sclerosis
Autolus has advanced obe-cel into initial clinical development to explore treatment in progressive MS. The first patient in the BOBCAT trial was dosed in October 2025. The Phase 1 trial, expected to include up to 18 adult patients, will determine the safety, tolerability, and preliminary efficacy of obe-cel in participants with refractory progressive forms of MS. The Company expects to report initial data from the trial at the end of 2026 and full data in 2027.
AUTO8 in AL-Amyloidosis
The first patient was dosed in the Phase 1 ALARIC trial evaluating AUTO8 in light-chain amyloidosis and initial data is expected to be reported at the end of 2026.

Q4 2025 Operational Updates:

In the fourth quarter of 2025, Autolus initiated an overall manufacturing life cycle plan to facilitate additional cost reductions and gross margin improvements as the Company plans to expand obe-cel into new indications and pursue larger market opportunities. The initiatives are focused on 1) optimizing the Company’s current manufacturing operating model; 2) enhancing automation opportunities for the Company’s existing manufacturing process; and 3) developing a next-generation manufacturing platform with a step change in the cost and capacity profile. The Company plans to provide a detailed update on these plans in mid-2026.

Outlook:
For 2026, the Company continues to project AUCATZYL net product revenue of between $120 million to $135 million.

Increasing patient numbers in 2026 are expected to improve manufacturing plant utilization and together with operational efficiencies, Autolus expects a shift to positive gross margin in 2026.

Based on current operating plans, including anticipated AUCATZYL net revenues, Autolus expects that its current and projected cash, cash equivalents and marketable securities will be sufficient to fund the Company’s operations into Q4 2027.

Financial Results for the Quarter Ended December 31, 2025

Product revenue, net for the three months ended December 31, 2025, was $23.3 million*.

Cost of sales increased from $11.4 million to $25.3 million for the three months ended December 31, 2025, compared to the same period in 2024. This increase was primarily due to product sales in Q4 2025 and to the timing of commercial manufacturing activity expenses upon FDA approval of AUCATZYL in November 2024. Additionally, cost of sales in Q4 2025 includes cancelled orders in the period, patient access program product, inventory reserves and write-offs and third-party royalties for certain technology licenses.

Research and development expenses increased to $35.6 million from $30.8 million for the three months ended December 31, 2025, compared to the same period in 2024. This change was primarily due to an increase in research and development activities including clinical trial costs and a reduction in the UK R&D tax credit, partially offset by commercial manufacturing-related employee and infrastructure costs shifting to cost of sales and inventory.

Selling, general and administrative expenses increased to $35.8 million from $33.7 million for the three months ended December 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 commercialization activities.

Loss from operations for the three months ended December 31, 2025, was $72.5 million, as compared to $75.9 million for the same period in 2024.

Net loss was $90.3 million for the three months ended December 31, 2025, compared to $27.6 million for the same period in 2024. Basic and diluted net loss per ordinary share for the three months ended December 31, 2025, totaled $(0.34), compared to basic and diluted net loss per ordinary share of $(0.10) for the same period in 2024.

Cash, cash equivalents and marketable securities at December 31, 2025, totaled $300.7 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 $18.6 million in the Company’s 2023 R&D tax credit expected from the UK HMRC.

Taletrectinib (marketed as IBTROZI in the U.S. and Japan) is a highly selective, next-generation oral treatment for patients living with advanced ROS1+ NSCLC. In January 2026, Eisai and Nuvation Bio announced they had entered into an exclusive licensing and collaboration agreement in Europe and additional countries* outside the U.S., China and Japan to extend the global reach of taletrectinib. Following this filing to the EMA, additional filings are planned for the U.K., Canada and other regions included in Eisai’s licensed territories.

Across Europe, nearly 400,000 people are diagnosed with lung cancer each year, with NSCLC accounting for 80% of cases. It is estimated that approximately 2% of patients with NSCLC have ROS1+ disease.

"The validation of the MAA is a significant moment for patients in Europe with ROS1+ NSCLC," said Terushige Iike, Chief Business Officer of Eisai Co., Ltd. "With its efficacy and safety profile, we believe taletrectinib has the potential to become a standard of care therapy for the thousands of patients living with this aggressive disease in Europe. We look forward to working closely with the EMA during the review process with the goal of making this treatment available to appropriate patients who urgently need targeted options."

The application is based on data from the two pivotal Phase 2 clinical studies, TRUST-I and TRUST-II, evaluating taletrectinib in patients globally. Results from a pooled analysis of the TRUST clinical program were published in the Journal of Clinical Oncology in April 2025, and Nuvation Bio anticipates near-term disclosure of updated data reflecting even longer patient follow-up, further building on the depth and durability of responses observed to date. Additionally, given the comprehensive nature of the taletrectinib clinical dataset and based on favorable feedback received at a pre-submission meeting with the CHMP Rapporteur and Co-Rapporteur, the accepted MAA will be considered to support full approval.

"Having seen the meaningful impact taletrectinib has already made for patients with ROS1+ NSCLC in the U.S., China and Japan, we are thrilled to partner with Eisai and have an accepted MAA for review in Europe," said David Hung, M.D., Founder, President and Chief Executive Officer of Nuvation Bio. "This accepted filing represents an important milestone in our global development strategy and brings us one step closer to delivering this highly selective, next-generation oral therapy to more patients who need it in Europe and around the world."

In June 2025, the U.S. Food and Drug Administration (FDA) granted full approval to taletrectinib for the treatment of locally advanced or metastatic ROS1+ NSCLC across lines of therapy, following a Priority Review and double Breakthrough Therapy designations. Taletrectinib is also approved for patients with advanced ROS1+ NSCLC in Japan, where it is marketed by Nippon Kayaku, and in China, where it is marketed by Innovent Biologics under the brand name DOVBLERON.

* Eisai’s licensed territories: Europe, the Middle East, North Africa, Russia, Turkey, Canada, Australia, New Zealand, Singapore, the Philippines, Indonesia, Thailand, Malaysia, Vietnam and India.

About ROS1+ NSCLC
Each year, more than one million people globally are diagnosed with non-small cell lung cancer (NSCLC), the most common form of lung cancer. It is estimated that approximately 2% of patients with NSCLC have ROS1+ disease. About 35% of patients newly diagnosed with metastatic ROS1+ NSCLC have tumors that have spread to their brain. The brain is also the most common site of disease progression, with about 50% of previously treated patients developing central nervous system (CNS) metastases.

About Taletrectinib
Taletrectinib is an oral, potent, CNS-active, selective, next-generation ROS1 inhibitor therapy. On June 11, 2025, following Priority Review and Breakthrough Therapy designations for both TKI-naive and TKI-pretreated disease, the U.S. Food and Drug Administration (FDA) approved taletrectinib for the treatment of adult patients with locally advanced or metastatic ROS1+ NSCLC. Learn more about taletrectinib in the U.S. at IBTROZI.com.

About the TRUST Clinical Program
The TRUST clinical program comprises three registrational studies evaluating the safety and efficacy of taletrectinib. TRUST-I (NCT04395677) and TRUST-II (NCT04919811) are Phase 2 single-arm studies evaluating taletrectinib for the treatment of adults with advanced ROS1+ NSCLC in China (N=173) and globally (N=189), respectively. The primary endpoint of both studies is confirmed objective response rate (cORR) as assessed by an independent review committee. TRUST-IV (NCT07154706) is a Phase 3 placebo-controlled study evaluating taletrectinib for the adjuvant treatment of adults with resected early-stage ROS1+ NSCLC. The study will enroll approximately 180 patients in the U.S., Canada, Europe, Japan and China. The primary endpoint is disease-free survival as determined by investigator, and the primary completion date is estimated to be in 2030. Nuvation Bio is also sponsoring TRUST-III (NCT06564324), a confirmatory randomized Phase 3 study evaluating taletrectinib versus crizotinib in 138 patients in China with advanced ROS1+ NSCLC who have not previously received ROS1 TKIs.
