▶ 这是希维奥^®在韩国斩获的第三项适应症，用于治疗多发性骨髓瘤（MM）患者。

▶ 希维奥^®已在韩国、中国大陆、澳大利亚和新加坡实现医保收录，公司预计其将在亚太地区的更多市场获得医保收录。

▶ 希维奥^®已在亚太市场的9个国家和地区获批用于治疗多种适应症，公司还在印度尼西亚提交了产品的新药上市申请（NDA），预计于今年下半年获批。

中国上海和香港，2024年10月18日–致力于研发，生产和销售同类首款及/或同类最优血液及实体肿瘤疗法的商业化阶段领先创新生物制药公司–德琪医药有限公司（简称“德琪医药”，香港交易所股票代码：6996.HK）今日宣布，韩国食品医药品安全部（MFDS）已批准希维奥^®（塞利尼索片）的补充新药上市申请（sNDA），联合硼替佐米和地塞米松用于治疗至少接受过一种先前治疗的多发性骨髓瘤（MM）成人患者。

此前，希维奥^®已在韩国获批联合地塞米松用于治疗复发/难治性多发性骨髓瘤（R/R MM）和单药治疗复发/难治性弥漫性大B细胞淋巴瘤（R/R DLBCL）两项适应症。今年7月，希维奥^®获纳入韩国医保报销药品目录，成为首款纳入韩国医保的XPO1抑制剂。

希维奥^®是全球首个全新机制的口服选择性XPO1抑制剂，已在亚太市场的9个国家和地区获批用于治疗多种适应症，并在其中4个市场（韩国、中国大陆、澳大利亚和新加坡）实现医保收录。此次希维奥^®又一新适应症在韩国获批上市，将为韩国的MM患者带来更为丰富的创新治疗选择，惠及更多患者及其家庭。

在持续推进亚太市场布局的同时，公司也正努力扩充希维奥^®的适应症范围。基于其独特的作用机制，公司正在开发希维奥^®在骨髓纤维化（MF）和子宫内膜癌等不同疾病领域的多种联合疗法。

关于希维奥^®（塞利尼索）

希维奥^®是全球首个全新机制的口服选择性核输出蛋白（XPO1）抑制剂，具有“全新机制、协同增效、快速起效、持久缓解”四大特点。

通过抑制核输出蛋白XPO1，希维奥^®可促使肿瘤抑制蛋白和其他生长调节蛋白的核内储留和活化，并下调细胞浆内多种致癌蛋白水平。希维奥^®发挥抗肿瘤作用机制的三条通路为：1）使抑癌蛋白在细胞核中明显聚集，再激活发挥抗肿瘤作用；2）使致癌基因mRNA滞留在细胞核，降低胞浆内致癌蛋白水平；3）激活糖皮质激素受体（GR）通路，恢复激素敏感性。基于其独特的作用机制，希维奥^®在不同疾病领域的多种联合疗法正在进行开发。目前，德琪医药正在中国大陆地区开展多项（其中三项全球临床试验由德琪医药与Karyopharm Therapeutics Inc.[纳斯达克交易所股票代码：KPTI] 共同开展）针对复发/难治性血液及实体肿瘤的临床研究。

Antengene Announces XPOVIO^® (selinexor) Approved for Its Third Indication in South Korea, Bringing Fresh Hope to Patients with MM in the Country

- This approval for XPOVIO^® for the treatment of patients with multiple myeloma (MM) marks the third approved indication of the drug in South Korea.

- To date, XPOVIO^® has already been included in national health insurance or reimbursement schemes in South Korea, the mainland of China, Australia and Singapore, and is expected to achieve national reimbursement coverage in more APAC markets.

- XPOVIO^® has been approved for multiple indications in nine markets across the APAC region. Antengene has submitted a new drug application (NDA) for XPOVIO^® in Indonesia with approval expected in the second half of 2024.

Shanghai and Hong Kong, PRC, October 18, 2024 — Antengene Corporation Limited (“Antengene”, SEHK: 6996.HK), a leading innovative, commercial-stage global biopharmaceutical company dedicated to discovering, developing and commercializing first-in-class and/or best-in-class medicines for hematologic malignancies and solid tumors, today announced that the South Korean Ministry of Food and Drug Safety (MFDS) has approved a supplemental New Drug Application (sNDA) for XPOVIO^® (selinexor) in combination with bortezomib and dexamethasone for the treatment of adult patients with multiple myeloma (MM) who have received at least one prior therapy.

Prior to the recent approval, XPOVIO^® has been approved for two indications in South Korea that are: in combination with dexamethasone for the treatment of adult patients with relapsed or refractory MM (R/R MM); and as a monotherapy for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL). In July 2024, XPOVIO^® was included into the reimbursement drug list in South Korea, thus became the first XPO1 inhibitor approved for public insurance coverage in the country.

With a novel mechanism of action, XPOVIO^® is the world’s first approved orally-available, selective XPO1 inhibitor, which has already been approved in nine countries and regions in APAC and included in the national insurance schemes in South Korea, the mainland of China, Australia and Singapore. This recent approval for XPOVIO^® in South Korea will bring another innovative therapy to the clinical management of MM patients in South Korea, benefiting countless patients and families.

While bringing XPOVIO^® to more APAC markets, Antengene is also striving to expand the indications of XPOVIO^®. Leveraging the drug’s novel mechanism of action, Antengene is currently developing multiple combination regimens of XPOVIO^® for the treatment of various indications including myelofibrosis (MF), and endometrial cancer.

About XPOVIO^® (selinexor)

XPOVIO^® is the world’s first approved orally-available, selective inhibitor of the nuclear export protein XPO1. It offers a novel mechanism of action, synergistic effects in combination regimens, fast onset of action, and durable responses.

By blocking the nuclear export protein XPO1, XPOVIO^® can promote the intranuclear accumulation and activation of tumor suppressor proteins and growth regulating proteins, and down-regulate the levels of multiple oncogenic proteins. XPOVIO^® delivers its antitumor effects through three mechanistic pathways: 1) exerting antitumor effects by inducing the intranuclear accumulation of tumor suppressor proteins; 2) reducing the level of oncogenic proteins in the cytoplasm by inducing the intranuclear accumulation of oncogenic mRNAs; 3) restoring hormone sensitivity by activating the glucocorticoid receptors (GR) pathway. To utilize its unique mechanism of actions, XPOVIO^® is being evaluated for use in multiple combination regimens in a range of indications. At present, Antengene is conducting multiple clinical studies of XPOVIO^® in the mainland of China for the treatment of relapsed/refractory hematologic malignancies and solid tumors (3 of these studies are being jointly conducted by Antengene and Karyopharm Therapeutics Inc. [Nasdaq:KPTI]).
