TAGRISSO® (osimertinib) plus savolitinib demonstrated statistically significant and clinically meaningful improvements in progression-free and overall survival in MET-driven EGFR-mutated lung cancer after progression on TAGRISSO
Positive high-level results from the SAFFRON Phase III trial showed TAGRISSO® (osimertinib) plus 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 tumors 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’ tumors 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 Jiaotong 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 savolitinib to backbone therapy TAGRISSO to address MET overexpression or amplification while maintaining EGFR suppression. By combining savolitinib and TAGRISSO, with its established efficacy, safety profile and central nervous system protection, weaim 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 savolitinib 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 savolitinib 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 savolitinib 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.
Savolitinib is being jointly developed by AstraZeneca and HUTCHMED and commercialized by AstraZeneca.
TAGRISSO® (osimertinib)
TAGRISSO® (osimertinib) is a third-generation, irreversible EGFR-TKI with proven clinical activity in NSCLC, including the treatment of central nervous system metastases. TAGRISSO (40 mg and 80 mg 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.
