HUTCHMED and AstraZeneca Announce that TAGRISSO® Plus Savolitinib Demonstrated 49% Objective Response Rate in Lung Cancer Patients with High Levels of MET Overexpression and/or Amplification in SAVANNAH Phase II Trial

On August 8, 2022, HUTCHMED (China) Limited and AstraZeneca PLC announced that preliminary results from the SAVANNAH Phase II trial showed that TAGRISSO® (osimertinib) plus savolitinib demonstrated an objective response rate (“ORR”) of 49% (95% confidence interval [“CI”], 39-59%) in patients with epidermal growth factor receptor-mutated (“EGFRm”) non-small cell lung cancer (“NSCLC”) with high levels of mesenchymal epithelial transition (“MET”) overexpression and/or amplification, defined as IHC90+ and/or FISH10+, whose disease progressed on treatment with TAGRISSO®.

The highest ORR was observed in patients with high levels of MET who were not treated with prior chemotherapy (52% [95% CI, 41-63%]). In patients whose tumors did not show high levels of MET, the ORR was 9% (95% CI, 4-18%). These results are being shared at the International Association for the Study of Lung Cancer (IASLC) 2022 World Conference on Lung Cancer (WCLC), taking place on August 6-9, 2022 in Vienna, Austria.

Savolitinib, marketed in China under the brand name ORPATHYS®, is an oral, potent and highly selective MET tyrosine kinase inhibitor (“TKI”) being jointly developed and commercialized by AstraZeneca and HUTCHMED.

While EGFR-targeted therapy can provide a durable survival benefit to patients with EGFRm NSCLC, most will eventually develop resistance to their treatment, with MET being the most common resistance biomarker.1 Among patients screened for enrolment in SAVANNAH, all of whom experienced disease progression on TAGRISSO®, 62% had tumors with MET overexpression and/or amplification, and more than one-third (34%) met the defined high MET level cut-off.

Myung-Ju Ahn, MD, PhD, Professor of Hemato-Oncology at the Department of Medicine, Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, South Korea, and Principal Investigator in the SAVANNAH Phase II trial, said: “Acquired resistance to targeted therapy and disease progression are difficult realities for most patients with EGFR-mutated NSCLC. These preliminary SAVANNAH results potentially support a novel approach for identifying patients with MET overexpression and/or amplification who are most likely to benefit from a MET-directed therapy, like savolitinib. They also suggest that with the right biomarker testing strategy, MET may be a more prevalent target among resistant patients than previously understood, supporting further investigation of the osimertinib plus savolitinib regimen.”

Cristian Massacesi, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca said: “The current standard of care for patients with EGFR-mutated lung cancer who progress on targeted treatment is chemotherapy. The results from SAVANNAH suggest savolitinib added to TAGRISSO® at the time of disease progression could possibly provide these biomarker-selected patients with a potentially less toxic, more effective treatment option. We look forward to better understanding the potential of the TAGRISSO® plus savolitinib regimen in this trial and in the SAFFRON Phase III trial.”

Weiguo Su, Chief Executive Officer and Chief Scientific Officer, HUTCHMED, said: “It is encouraging to see the savolitinib and TAGRISSO® combination regimen progress into a global Phase III study, SAFFRON, with a well-supported patient selection strategy that could benefit more patients than previously recognized. The preliminary results of the SAVANNAH study also affirm the role of molecular testing prior to initiating subsequent treatment for NSCLC patients who experience disease progression on an EGFR-targeted therapy. We are aligned in pursuing a selective, patient-centric approach in development efforts for savolitinib in this setting.”

In this analysis, patients’ MET overexpression and/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 hybridization (“FISH”), which detects a specific DNA sequence from cancer cells. All patients in this analysis (n=193) had at least IHC50+ and/or FISH5+, and were treated with savolitinib 300mg once daily added to TAGRISSO® 80mg once daily following disease progression on TAGRISSO® alone.

HUTCHMED Announces that Fruquintinib Global Phase III FRESCO-2 Study Has Met Its Primary Endpoint in Metastatic Colorectal Cancer

On August 7, 2022, HUTCHMED (China) Limited announced that the pivotal global Phase 3 FRESCO-2 trial evaluating the investigational use of fruquintinib met its primary endpoint of overall survival (“OS”) in patients with advanced, refractory metastatic colorectal cancer (“CRC”).

The FRESCO-2 study was a multi-regional clinical trial conducted in the U.S., Europe, Japan and Australia that investigated fruquintinib plus best supportive care (“BSC”) vs placebo plus BSC in patients with metastatic CRC who had progressed on standard chemotherapy and relevant biologic agents and who had progressed on, or were intolerant to, TAS-102 and/or regorafenib. In addition to OS, a statistically-significant improvement in progression-free survival (“PFS”), a key secondary endpoint, was observed. The safety profile of fruquintinib in FRESCO-2 was consistent with previously reported studies. Full results will be submitted for presentation at an upcoming medical meeting.

HUTCHMED has been in communication with regulatory agencies globally regarding the FRESCO-2 trial design and conduct and will discuss these data with the agencies in the U.S., Europe and Japan with the intent to submit marketing authorization applications as soon as possible. The U.S. FDA granted Fast Track Designation for the development of fruquintinib for the treatment of patients with metastatic CRC in June 2020.

“We are very happy to see the positive outcomes of the FRESCO-2 study which offers a potential new treatment for patients with advanced metastatic colorectal cancer, where the unmet need is very high and patients have limited treatment options,” said Dr Marek Kania, Executive Vice President, Managing Director and Chief Medical Officer of HUTCHMED International. “Results from the global FRESCO-2 study supplement findings from the original FRESCO study that led to the marketing approval and commercialization of fruquintinib in China. We would like to thank the patients, their families, and the healthcare professionals who participated in this study and helped achieve this important milestone.”

Professor Cathy Eng, MD, FACP, FASCO, David H. Johnson Endowed Chair in Surgical and Medical Oncology and Co-Leader, Gastrointestinal Cancer Research Program, at the Vanderbilt-Ingram Cancer Center, who served as the FRESCO2 co-PI and Steering Committee member said: “Completion of the international FRESCO-2 phase III trial in a timely fashion during the era of COVID-19 isolation demonstrates the unmet need for new therapeutic agents in metastatic colorectal cancer. By meeting the primary endpoint of OS with a secondary endpoint of PFS, fruquintinib provides a significant potential new option for our refractory colorectal cancer patients. As an oral agent, fruquintinib also provides added convenience for our patients. Based on fruquintinib’s profile, we will likely see further exploration in future clinical trials in different settings. This is extremely encouraging, and I look forward to seeing the final results.”

Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED, said: “We are pleased to have successfully completed our first multi-regional clinical trial, FRESCO-2, to support the global registration of fruquintinib. It has already benefited patients with advanced CRC in China since its launch in 2018. It is also being evaluated alone and in combination with other agents in various tumor types in ongoing studies around the world.”

HUTCHMED retains all commercial rights to fruquintinib outside of China. In China, where fruquintinib is marketed under the brand name ELUNATE®, HUTCHMED is partnered with Eli Lilly and Company and is responsible for development and execution of all on-the-ground medical detailing, promotion and local and regional marketing. Fruquintinib is not approved for use outside of China.
