On August 17, 2026 Astrazeneca reported that positive high-level results from the SAFFRON Phase III trial showed Tagrisso (osimertinib) plus Orpathys (savolitinib) demonstrated a statistically significant and clinically meaningful improvement in both progression-free survival (PFS) and overall survival (OS) versus doublet platinum-based chemotherapy in patients with epidermal growth factor receptor-mutated (EGFRm) non-small cell lung cancer (NSCLC). Patients in the trial had tumours with high levels of MET overexpression or amplification and had progressed on prior treatment with Tagrisso.

Third-generation EGFR-tyrosine kinase inhibitors (TKIs) have significantly improved outcomes for patients with EGFRm NSCLC.1 However, one in three patients’ tumours will develop MET overexpression or amplification, one of the most common mechanisms of resistance on third-generation EGFR-TKIs.1-2 MET-driven resistance is associated with poor prognosis, and there is a significant unmet need for effective and well-tolerated treatment options in later-line settings.2

Professor Shun Lu, Director of Shanghai Lung Cancer Center, Shanghai Chest Hospital, Shanghai Jiao Tong University School of Medicine and principal investigator of the trial, said: "These exciting results from SAFFRON represent a critical advance for patients with EGFR-mutated non-small cell lung cancer experiencing MET-driven resistance after osimertinib, a population with poor outcomes and no biomarker-directed treatment options available that are oral and well-tolerated. MET is one of the most common drivers of progression on targeted therapy in this setting, and these data underscore the potential impact of this novel osimertinib plus savolitinib combination and the urgency of MET testing to inform treatment decisions."​ ​

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "These data demonstrate the clear benefit of adding Orpathys to backbone therapy Tagrisso to address MET overexpression or amplification while maintaining EGFR suppression. By combining Orpathys and Tagrisso, with its established efficacy, safety profile and central nervous system protection, we aim to deliver the first biomarker-directed, all-oral option in this setting to patients across the globe. This further strengthens our leadership in EGFR-mutated lung cancer, reinforcing our strategy to improve patient outcomes across stages and through lines of therapy with novel combinations."

Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED, said: "Overcoming MET-driven resistance after EGFR-TKI therapy has been a long-standing challenge in clinical practice. The SAFFRON global study further reinforces the robust efficacy previously demonstrated in the SACHI Phase III trial that supported approval in China, with the results providing clear evidence to support global registrations of the Tagrisso and Orpathys combination. We are grateful to everyone who supported this trial. Together with AstraZeneca, we look forward to potentially bringing this landmark treatment to patients around the world."

The safety profile for Tagrisso plus Orpathys was consistent with the known profiles of each medicine, and there were no new safety findings. These data will be presented at a forthcoming medical meeting and shared with global regulatory authorities.

Tagrisso plus Orpathys is approved in China for patients with locally advanced or metastatic EGFRm NSCLC with MET amplification after disease progression on EGFR-TKI therapy based on the SACHI Phase III trial.

Orpathys is being jointly developed by AstraZeneca and HUTCHMED and commercialised by AstraZeneca.

Notes

NSCLC and MET aberrations
Lung cancer is the leading cause of cancer death globally, accounting for almost one in four (23%) cancer deaths.3 Lung cancer is broadly split into NSCLC and small cell lung cancer, with 80-85% of patients diagnosed with NSCLC.4 Approximately 75% of NSCLC patients are diagnosed with advanced disease.5 Additionally, about 10-15% of NSCLC patients in the US and Europe, and 30-40% of patients in Asia, have EGFRm NSCLC.​6-8

MET is a tyrosine kinase receptor that has an essential role in normal cell development.9 MET overexpression or amplification can lead to tumour growth and the metastatic progression of cancer cells.9-10 An estimated 34% of tumours will develop high levels of MET overexpression or amplification after progression on a third-generation EGFR-TKI.1 ​

SAFFRON
SAFFRON is a randomised, open-label, multi-centre, global Phase III trial studying the efficacy of Orpathys (300mg twice daily) added to Tagrisso (80mg once daily) versus doublet platinum-based chemotherapy in 338 patients with EGFRm, locally advanced or metastatic NSCLC with MET overexpression or amplification whose disease progressed following 1st- or 2nd-line treatment with Tagrisso. The trial enrolled patients in 230 centres across 29 countries, including in North America, Europe, South America and Asia. The primary endpoint is PFS and key secondary endpoints include OS and objective response rate.

Patients were prospectively selected for SAFFRON using the high MET level cut-offs identified in the SAVANNAH Phase II trial.​ In SAVANNAH, MET overexpression or amplification levels were determined by two tests: immunohistochemistry (IHC), which detects if cancer cells have a particular protein or marker on their surface, and fluorescence in situ hybridisation (FISH), which detects a specific DNA sequence from cancer cells.

Orpathys
Orpathys (savolitinib) is an oral, potent and highly selective MET-TKI that has demonstrated clinical activity in advanced solid tumours. It blocks atypical activation of the MET receptor tyrosine kinase pathway that occurs because of mutations (such as exon 14 skipping alterations or other point mutations), gene amplification or protein overexpression.

Orpathys is approved in China for the treatment of adult patients with locally advanced or metastatic NSCLC with MET exon 14 skipping alteration, representing the first selective MET inhibitor approved in China. Orpathys also received a conditional approval in China for the treatment of patients with locally advanced or metastatic gastric cancer or gastroesophageal junction adenocarcinoma with MET amplification who have failed at least two prior systemic treatments.

Orpathys in combination with Tagrisso is approved in China for patients with locally advanced or metastatic EGFRm-positive non-squamous NSCLC with MET amplification after disease progression on EGFR-TKI therapy based on the SACHI Phase III trial. The combination was also granted a temporary authorisation in Switzerland for the treatment of patients with locally advanced or metastatic EGFRm NSCLC and high levels of MET overexpression or amplification who progressed on prior treatment with Tagrisso. This was based on results from the global SAVANNAH Phase II trial.

Tagrisso
Tagrisso (osimertinib) is a third-generation, irreversible EGFR-TKI with proven clinical activity in NSCLC, including the treatment of central nervous system metastases. Tagrisso (40mg and 80mg QD oral tablets) has been used to treat more than one million patients across its indications worldwide and AstraZeneca continues to explore Tagrisso as a treatment for patients across multiple stages of EGFRm NSCLC.

Tagrisso is approved as monotherapy in more than 120 countries including the US, EU, China and Japan. Approved indications include for 1st-line treatment of patients with locally advanced or metastatic EGFRm NSCLC, locally advanced or metastatic EGFR T790M mutation-positive NSCLC, adjuvant treatment of early-stage EGFRm NSCLC and locally advanced, unresectable NSCLC following platinum-based chemoradiation therapy. Tagrisso is also approved in combination with chemotherapy in more than 80 countries, including the US, EU, China and Japan, for 1st-line treatment of patients with locally advanced or metastatic EGFRm NSCLC.

There is an extensive body of evidence supporting the use of Tagrisso in EGFRm NSCLC, and it is the only targeted therapy shown to improve patient outcomes across all stages of the disease.

In late-stage disease, Tagrisso demonstrated improved outcomes as monotherapy in the FLAURA Phase III trial and in combination with chemotherapy in the FLAURA2 Phase III trial. Tagrisso is also being investigated in this setting in combination with Datroway (datopotamab deruxtecan or Dato-DXd) in the TROPION-Lung14 and TROPION-Lung15 Phase III trials.

Tagrisso also showed improved outcomes in early-stage disease in the NeoADAURA and ADAURA Phase III trials and in locally advanced stages in the LAURA Phase III trial. As part of AstraZeneca’s ongoing commitment to treating patients as early as possible in lung cancer, Tagrisso is also being investigated in the early-stage adjuvant resectable setting in the ADAURA2 Phase III trial.

This decision is based on the recommendation of the Independent Data Monitoring Committee (IDMC) following a planned review of trial data. The IDMC concluded that the volrustomig combination was unlikely to meet either of the dual primary endpoints of progression-free survival (PFS) or overall survival (OS) in the primary analysis population of patients with PD-L1 negative tumours (<1%) versus the comparator arm.

The safety profile of volrustomig plus chemotherapy was consistent with the known profiles of the individual medicines and no new safety signals were identified.

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "We initiated the eVOLVE-Lung02 trial aiming to improve the outcomes for patients whose lung cancers have lower PD-L1 expression and a less durable response to current immunotherapy regimens. While we are disappointed, we will learn from this trial and are determined to continue pioneering new medicines from our industry-leading pipeline in our quest to improve outcomes for patients with lung cancer."

The Company will work with investigators to ensure continuity of care and appropriate follow up for patients on the trial. The other Phase III volrustomig trials continue as planned in cervical cancer, head and neck squamous cell carcinoma and mesothelioma.

Notes

NSCLC
Lung cancer is the leading cause of death by cancer globally, accounting for almost one in four (23%) cancer deaths.1 Lung cancer is broadly split into small cell lung cancer or NSCLC, the latter accounting for 80-85% of cases.1-2 Patients are most commonly diagnosed with metastatic disease, when the tumour has spread outside the lung.3 Approximately 12% of people with metastatic NSCLC will still be alive five years after diagnosis.4

eVOLVE-Lung02
eVOLVE-Lung02 is a randomized, open-label, multi-centre, global Phase III trial of volrustomig plus chemotherapy for 1st-line treatment of patients with mNSCLC whose tumours express PD-L1 <50%. Patients were randomized 1:1 to receive 750mg intravenous volrustomig in combination with chemotherapy every three weeks for four cycles followed by volrustomig every three weeks, or 200mg pembrolizumab plus chemotherapy every three weeks for four cycles followed by pembrolizumab every three weeks until completion of 24 months of treatment or disease progression, or other discontinuation criterion are met.

The trial enrolled 895 patients across 25 countries. The dual primary endpoints were progression-free survival (PFS) and overall survival (OS) in patients whose tumours express PD-L1 <1%. Secondary endpoints included PFS and OS in the intent-to-treat population (PD-L1 <50%).

Volrustomig
Volrustomig is a dual checkpoint inhibitor bispecific antibody designed to deliver coordinated and targeted PD-1 and CTLA-4 blockade on the same T cell. AstraZeneca is evaluating volrustomig as monotherapy and in combinations in several tumour types with high unmet need.

On August 17, 2026 Astrazeneca and Daiichi Sankyo reported positive high-level results from the DESTINY-Lung04 Phase III trial showed Enhertu (trastuzumab deruxtecan) demonstrated a statistically significant and clinically meaningful improvement in progression-free survival (PFS) versus global standard of care (platinum-pemetrexed doublet chemotherapy plus pembrolizumab) as 1st-line treatment of patients with unresectable, locally advanced or metastatic HER2-mutant non-squamous non-small cell lung cancer (NSCLC). The trial will continue as planned to evaluate secondary endpoints including overall survival.

The global standard of care for patients with HER2-mutant NSCLC in the 1st-line metastatic setting is a combination of immunotherapy and platinum-based chemotherapy.1-3 However, many patients do not respond to 1st-line treatment and experience disease progression, underscoring the need for additional treatment options.3-7 Approximately 2-4% of patients with NSCLC have tumours with a HER2 mutation.8-10

Susan Galbraith, Executive Vice President, Oncology Haematology R&D, AstraZeneca, said: "Our oncology pipeline continues to advance with DESTINY-Lung04 becoming the first Phase III trial to demonstrate a progression-free survival benefit versus the global standard of care in this first-line setting, supporting the potential for Enhertu to move earlier in the treatment of HER2-mutant non-small cell lung cancer. This aggressive lung cancer often affects younger patients and has historically had limited first-line targeted treatment options, making these positive results an important step forward in bringing additional effective therapies to patients at metastatic diagnosis when there is the greatest opportunity to improve outcomes."

John Tsai, Global Head, R&D, Daiichi Sankyo, said: "Enhertu is already established as the first and only antibody drug conjugate for the second-line treatment of HER2-mutant metastatic non-small cell lung cancer. The positive results seen in DESTINY-Lung04 show that treatment with Enhertu in the first-line setting delays disease progression compared to the global standard of care, highlighting its potential to improve outcomes for patients earlier in the treatment of metastatic disease."

The safety profile of Enhertu observed in DESTINY-Lung04 was generally consistent with its known profile, with no new safety concerns identified.

The DESTINY-Lung04 data will be presented at a forthcoming medical meeting and shared with global regulatory authorities.

Enhertu is currently approved to treat patients with previously treated metastatic NSCLC whose tumours have activating HER2 (ERBB2) mutations, and to treat patients with HER2-positive solid tumours, including HER2-overexpressing metastatic NSCLC, who have received prior treatment and who have no satisfactory treatment options.

Enhertu is a specifically engineered HER2-directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo and being jointly developed and commercialised by AstraZeneca and Daiichi Sankyo.

Notes

HER2-mutant NSCLC
Lung cancer is the most commonly diagnosed cancer globally and remains the leading cause of cancer-related death in both men and women.11 In 2024, approximately 2.6 million new lung cancer cases were reported worldwide, with an estimated 1.8 million deaths.11 NSCLC is the most common type of lung cancer, accounting for approximately 85% of cases.12 Prognosis is particularly poor for patients with metastatic NSCLC as only approximately 10% will live beyond five years after diagnosis.13-15

HER2 is a tyrosine kinase receptor protein involved in cell growth and differentiation and expressed on the surface of multiple tumour types. HER2 mutations have been identified in NSCLC as distinct molecular targets and have been reported in approximately 2-4% of patients with non-squamous NSCLC.8-10 These HER2 mutations are predominantly seen in younger women and people with no smoking history and have been independently associated with cancer cell growth and poor prognosis, with an increased incidence of brain metastases.8,16-20

The global standard of care in the 1st-line metastatic setting for patients with HER2-mutant NSCLC is a combination of immunotherapy and platinum-based chemotherapy.1-3 While these treatment regimens have been shown to improve survival in NSCLC, many patients do not respond to 1st-line treatment and experience disease progression, underscoring the need for additional treatment options.3-7

DESTINY-Lung04
DESTINY-Lung04 is a global, randomised, open-label, Phase III trial evaluating the efficacy and safety of Enhertu (5.4mg/kg) compared to standard of care (platinum-pemetrexed doublet chemotherapy in combination with pembrolizumab) in patients with unresectable, locally advanced or metastatic, non-squamous NSCLC harbouring a HER2 exon 19 or 20 mutation.

Patients were randomised 1:1 to receive either Enhertu or standard of care. Randomisation was stratified by smoking history and presence or history of brain metastasis. The primary endpoint of DESTINY-Lung04 is PFS as assessed by blinded independent central review (BICR). Secondary endpoints include OS, investigator-assessed PFS, overall response rate and duration of response as assessed by BICR and investigator, pharmacokinetics and safety.

DESTINY-Lung04 enrolled 454 patients across multiple sites in Asia, Europe and North America. For more information about the trial, visit ClinicalTrials.gov.

Enhertu
Enhertu is a HER2-directed ADC. Designed using the proprietary DXd ADC Technology of Daiichi Sankyo, Enhertu is the lead ADC in the oncology portfolio of Daiichi Sankyo and the most advanced programme in AstraZeneca’s ADC scientific platform. Enhertu consists of a HER2 monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers.

Enhertu (5.4mg/kg) followed by THP is approved in the US, China, Singapore and India as a neoadjuvant treatment for adult patients with HER2-positive (IHC 3+ or ISH+) Stage II or III breast cancer based on the results from the DESTINY-Breast11 trial. Continued approval in China for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

Enhertu (5.4mg/kg) is approved in Brazil and the US as an adjuvant treatment for adult patients with HER2-positive (IHC 3+ or ISH+) breast cancer who have residual invasive disease following trastuzumab (with or without pertuzumab) and taxane-based treatment based on the DESTINY-Breast05 trial.

Enhertu (5.4mg/kg) in combination with pertuzumab is approved in more than ten countries as a 1st-line treatment for adult patients with unresectable or metastatic HER2-positive (IHC 3+ or ISH+) breast cancer based on the results from the DESTINY-Breast09 trial.

Enhertu (5.4mg/kg) is approved in more than 75 countries worldwide for the treatment of adult patients with unresectable or metastatic hormone receptor (HR)-positive, HER2-low (IHC 1+ or IHC 2+/ ISH-) or HER2-ultralow (IHC 0 with membrane staining) breast cancer, as determined by a locally or regionally authorised test, that have progressed on one or more endocrine therapies in the metastatic setting based on the results from the DESTINY-Breast06 trial.

Enhertu (5.4mg/kg) is approved in more than 100 countries worldwide for the treatment of adult patients with unresectable or metastatic HER2-positive (IHC 3+ or ISH+) breast cancer who have received a prior anti-HER2-based regimen, either in the metastatic setting or in the neoadjuvant or adjuvant setting, and have developed disease recurrence during or within six months of completing therapy based on the results from the DESTINY-Breast03 trial.

Enhertu (5.4mg/kg) is approved in more than 100 countries worldwide for the treatment of adult patients with unresectable or metastatic HER2-low (IHC 1+ or IHC 2+/ISH) breast cancer who have received a prior systemic therapy in the metastatic setting or developed disease recurrence during or within six months of completing adjuvant chemotherapy based on the results from the DESTINY-Breast04 trial.

Enhertu (5.4mg/kg) is approved in more than 80 countries worldwide for the treatment of adult patients with unresectable or metastatic non-small cell lung cancer (NSCLC) whose tumours have activating HER2 (ERBB2) mutations, as detected by a locally or regionally approved test, and who have received a prior systemic therapy based on the results from the DESTINY-Lung02 and/or DESTINY-Lung05 trials.

"This was a quarter of important progress across our clinical, regulatory and commercialization programs as we move Multikine closer to patients," stated CEL-SCI CEO Geert Kersten. "Our recently published peer-reviewed data identified the biomarkers that allow us to prospectively select the patients most likely to benefit from Multikine—the same population in which our Phase 3 study demonstrated a 73% five-year survival rate compared with 45% for standard of care alone. By focusing our 212-patient Confirmatory Registration Study on this biomarker-selected population, we believe we have substantially increased the likelihood of confirming Multikine’s survival benefit and achieving a successful trial outcome. At the same time, our partnership with Amarox is advancing a potential near-term path to commercial availability in Saudi Arabia. With enrollment in our registration study set to commence globally, we believe we have never been better positioned to bring Multikine to patients and advance it toward commercialization."

Clinical and Corporate Developments:

A leading peer-reviewed journal, Oral Oncology , published biomarker selected population and survival data from CEL-SCI’s Phase 3 clinical study, the largest trial of its kind in the world. The article provides scientific evidence supporting the biomarker strategy that forms the foundation for selecting patients in CEL-SCI’s upcoming global Confirmatory Registration Study. Low and zero (0%) tumor PD-L1 expression and no lymph node involvement were identified as biomarkers for selecting patients most likely to benefit from Multikine pre-surgery treatment. The published study concludes that Multikine represents the first neoadjuvant treatment in decades to demonstrate an overall survival benefit in biomarker-selected patients with locally advanced resectable oral cancer. Multikine neoadjuvant treatment also demonstrated a statistically significant improvement in progression-free survival with a 49% reduction in the risk of disease progression in the same biomarker-selected patients.
CEL-SCI is set to commence enrollment in its 212-patient U.S. FDA Confirmatory Registration Study evaluating Multikine in newly diagnosed, locally advanced head and neck cancer patients at clinical sites in the U.S., Europe, Asia and South America. Because Multikine is administered for a short period before surgery, pre-surgical tumor responses can be evaluated within weeks following full enrollment, providing an early assessment of Multikine’s anti-tumor activity. CEL-SCI plans to use these early tumor response data to pursue potential accelerated approval in the U.S. while patients continue to be followed for overall survival.
CEL-SCI entered a strategic partnership with Amarox , one of Saudi Arabia’s fastest growing pharmaceutical companies to pursue regulatory approval, marketing and commercialization of Multikine for head and neck cancer in Saudi Arabia, with an optional extension for the Gulf Cooperation Council (GCC) countries including Bahrain, Kuwait, Oman, Qatar, and the United Arab Emirates. Amarox will support and coordinate the regulatory process with the Saudi Food and Drug Authority (SFDA), including pursuit of Breakthrough Medicine Designation—the granting of which could lead to immediate availability of Multikine for reimbursement/sale in Saudi Arabia. Amarox has ranked #1 for SFDA applications for critical and unavailable medicines for 3 consecutive years. CEL-SCI and Amarox will share net revenue from Saudi Arabian Multikine sales on a 50%/50% basis.
Gross proceeds of approximately $9.7 million were raised by CEL-SCI during the quarter.
