HUTCHMED Announces Agreement with NHSA for Inclusion of ORPATHYS in the National Reimbursement Drug List in China

Hong Kong, Shanghai & Florham Park, NJ -- Wednesday, January 18, 2023: HUTCHMED (China) Limited ("HUTCHMED") (Nasdaq/AIM: HCM; HKEX:13) today announces, following negotiations with the China National Healthcare Security Administration ("NHSA"), ORPATHYS (savolitinib) has been included in the updated National Reimbursement Drug List ("NRDL") for the treatment of locally advanced or metastatic non-small cell lung cancer ("NSCLC") adult patients with MET exon 14-skipping alterations who have progressed after or unable to tolerate platinum-based chemotherapy. The updated NRDL will take effect from March 1, 2023.

Savolitinib, marketed in China under the brand name ORPATHYS , is an oral, potent and highly selective MET tyrosine kinase inhibitor ("TKI") jointly developed by AstraZeneca and HUTCHMED with HUTCHMED taking the lead in China, and commercialized by AstraZeneca worldwide.

Dr Weiguo Su, Chief Executive Officer and Chief Scientific Officer of HUTCHMED, said: "The NRDL has significantly broadened access to novel medicines for Chinese patients. We are gratified to see that our third novel oncology medicine, ORPATHYS , will be included in this year's NRDL update. As the first and only selective MET inhibitor in the market, the inclusion of ORPATHYS will increase the affordability and access to this novel treatment."

Leon Wang, Executive Vice President, International and China President of AstraZeneca, said: "The inclusion of ORPATHYS on the NRDL is exciting news for NSCLC patients in China with MET exon 14 skipping alterations who will now have improved access to the only targeted medicine approved in this setting and who often do not respond well to chemotherapy. Since its launch in mid-2021, ORPATHYS has helped patients in need achieve better outcomes, and we are excited about the potential to reach even more patients in China with this transformational medicine."

ORPATHYS received conditional approval in China in June 2021 for the treatment of certain patients with NSCLC with MET exon 14 skipping alterations.

In recent years, the government in China has placed great importance on improving the affordability of drug treatments for the public. The NHSA regularly convenes a broad network of experts in medicine, pharmacology and pharmacoeconomics to identify innovative drugs to be considered for inclusion in the NRDL. This has led to an expansion of the reimbursement of Category B drugs, which increasingly include novel oncology drugs. Reimburse ment of Category B drugs requires varying degrees of copayment from patients, depending on their province of residence or type of NHSA insurance scheme enrollment. Inclusion on the NRDL for all listed drugs is subject to renewal every two years.

In this update round, the NHSA has added 23 oncology drugs to the NRDL, including ORPATHYS . Effective March 1, 2023, medicines included on the NRDL are expected to be made available in pharmacies of major hospitals in China at the negotiated price in accordance with NRDL payment standards, and reimbursement will commence for participants in the NHSA insurance schemes, subject to applicable co-payments by participants.

Savolitinib is an oral, potent and highly selective MET TKI 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 NSCLC 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.

About NSCLC and MET aberrations

Lung cancer is the leading cause of cancer death among men and women, accounting for about one-fifth of all cancer deaths.1 Lung cancer is broadly split into NSCLC and small cell lung cancer, with 80-85% classified as NSCLC.2 The majority of NSCLC patients (approximately 75%) are diagnosed with advanced disease, and approximately 10-15% of NSCLC patients in the U.S. and Europe and 30-40% of patients in Asia have EGFRm NSCLC. 3,4,5,6

MET is a tyrosine kinase receptor that has an essential role in normal cell development.7 MET overexpression and/or amplification can lead to tumor growth and the metastatic progression of cancer cells, and is the primary mechanism of acquired resistance to EGFR TKIs for metastatic EGFR-mutated NSCLC.7,8 Approximately 2-3% of NSCLC patients have tumors with MET exon 14 skipping alterations, a targetable mutation in the MET gene.9 Among patients who experience disease progression post-osimertinib treatment, approximately 15-50% present with MET aberration. 10,11,12,13,14 The prevalence of MET depends on the sample type, detection method and assay cut-off used.15

About AstraZeneca and HUTCHMED collaboration

In 2011, AstraZeneca and HUTCHMED entered into 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.
