HUTCHMED Highlights Presentation of Results from the Phase IIIb Trial of Savolitinib at the 2023 World Conference of Lung Cancer

Hong Kong, Shanghai & Florham Park, NJ — Tuesday, September 12, 2023: HUTCHMED (China) Limited (“HUTCHMED”) (Nasdaq/AIM: HCM, HKEX: 13) today announces that results from the confirmatory Phase IIIb clinical trial of savolitinib in patients with mesenchymal epithelial transition factor (“MET”) exon 14 skipping alteration non-small cell lung cancer (“NSCLC”), were presented during the  IASLC 2023 World Conference on Lung Cancer hosted by the International Association for the Study of Lung Cancer (“WCLC”), which took place from September 9 to 12, 2023 in Singapore.

 

Title: A Phase 3b Study of 1L Savolitinib in Patients with Locally Advanced or Metastatic NSCLC Harboring MET Exon 14 Mutation
Lead Author: Shun Lu, MD, head of Shanghai Lung Cancer Center, Shanghai Chest Hospital, Shanghai Jiaotong University
Type: Oral presentation
Abstract Number: OA21.03
Session: OA21. MET Matters in NSCLC
Date & Time: Tuesday, September 12, 2023, 2:32-2:42 pm Singapore time
Location: Room 406, Suntec Singapore Convention & Exhibition Centre

Here we reported initial efficacy and safety data from the first-line cohort of a confirmatory Phase IIIb trial conducted in China of savolitinib as a monotherapy in patients with NSCLC MET exon 14 skipping alterations (NCT04923945).  At data cut-off date of April 30, 2023, among the 84 patients in the tumor response evaluable set (TRES), objective response rate (ORR) was 60.7% (95% Confidence Interval (“CI”): 49.5% to 71.2%) and disease control rate (DCR) was 95.2% (95% CI: 88.3% to 98.7%), as assessed by an independent review committee.  At median follow-up of 11.1 months, median progression free survival (mPFS) was 13.8 months (95% CI: 9.7 months to not reached).  Median duration of response (DoR) and overall survival (OS) have not been reached.  No new safety signals were observed.

 

The other cohort of this confirmatory trial was fully enrolled in H1 2023 and included patients who received prior treatments. The trial follows the June 2021 approval of savolitinib as a monotherapy in this indication from China’s National Medical Products Administration (NMPA), which was based on positive results from a Phase II trial (NCT02897479). This confirmatory trial enrolled a more representative proportion of the different NSCLC subtypes, which may confer different prognostic outcomes.

 

More than a third of the world’s lung cancer patients are in China and, among those with NSCLC globally, approximately 2-3% have tumors with MET exon 14 skipping alterations. Savolitinib was launched and is marketed under the brand name ORPATHYS® by our partner, AstraZeneca for this patient population, representing the first selective MET inhibitor approved in China.

A Quantitative Continuous Scoring (QCS) algorithm is being developed as an automated methodology to identify patients who are most likely to respond to treatment.  This e-poster showcased the application of this method based on information collected in the Phase II SAVANNAH study.  The global Phase III study SAFFRON will serve as an additional independent validation cohort.

 

About Savolitinib (ORPATHYS® in China)

Savolitinib is an oral, potent and highly selective MET tyrosine kinase inhibitor that has demonstrated clinical activity in advanced solid tumors. 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.

 

Savolitinib is marketed in China under the brand name ORPATHYS® for the treatment of patients with non-small cell lung cancer with MET exon 14 skipping alterations who have progressed following prior systemic therapy or are unable to receive chemotherapy. It is currently under clinical development for multiple tumor types, including lung, kidney and gastric cancers, as a single treatment and in combination with other medicines. Starting on March 1, 2023, ORPATHYS® was included in the National Reimbursement Drug List (NRDL) for the treatment of locally advanced or metastatic NSCLC adult patients with MET exon 14-skipping alterations who have progressed after or unable to tolerate platinum-based chemotherapy.

 

In 2011, AstraZeneca and HUTCHMED entered a global licensing and collaboration agreement to jointly develop and commercialize savolitinib. Joint development of savolitinib in China is led by HUTCHMED, while AstraZeneca leads development outside of China. HUTCHMED is responsible for the marketing authorization, manufacturing and supply of savolitinib in China. AstraZeneca is responsible for the commercialization of savolitinib in China and worldwide. Sales of savolitinib are recognized by AstraZeneca.
