中国上海和香港，2024年9月23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，泰国食品药品监督管理局已批准希维奥^®（中文通用名：塞利尼索，英文商品名：XPOVIO^®）的新药上市申请（NDA）。用于两个适应症的治疗：（1）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；（2）联合地塞米松用于治疗接受过至少四种既往治疗且对至少两种蛋白酶体抑制剂、两种免疫调节剂和一种抗CD38单克隆抗体药物难治，并在接受最后一种治疗时出现疾病进展的MM成人患者。

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个国家和地区获得多项新药上市批准。此次希维奥^®成功在泰国获批上市，将为泰国的MM患者带来全新的创新治疗选择，惠及更多患者及其家庭。截至目前，希维奥^®已在中国大陆、澳大利亚、新加坡和韩国实现医保收录。

东盟拥有超过6亿人口，随着经济的稳步增长，已成为全球生物医药发展的重要潜力市场。人口老龄化的加速使东盟市场的整体疾病负担不断加重，社会对新型治疗药物的需求持续增加。德琪医药致力于改善东盟人民的健康福祉，继 8 月在马来西亚获得批准上市，本次在泰国正式获批以外，我们还预计于2024 年下半年取得印度尼西亚的正式获批。未来，公司将继续把更多创新药物带到东盟市场，以提升当地的医疗健康水平，造福更多患者。

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 Commercialization in Thailand

- XPOVIO^® is the first and only approved XPO1 inhibitor in Thailand.

- 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.

- XPOVIO^® has been approved for health insurance coverage in the mainland of China, Australia, Singapore and South Korea.

Shanghai and Hong Kong, PRC, September 23, 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 cancer, today announced that the Thailand Food and Drug Administration has approved a New Drug Application (NDA) for XPOVIO^® (selinexor) for two indications: (1) In combination with bortezomib and dexamethasone for the treatment of adult patients with multiple myeloma (MM) who have received at least one prior therapy; and (2) in combination with dexamethasone for the treatment of adult patients with MM who have received at least four prior therapies and whose disease is refractory to at least two proteasome inhibitors, two immunomodulatory agents and an anti-CD38 monoclonal antibody, and who have demonstrated disease progression on the last therapy.

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 markets in APAC. This successful approval for XPOVIO^® in Thailand will introduce novel therapies to the clinical management of patients with MM in Thailand, benefiting many patients and their families in the country. To date, XPOVIO^® has also been included in national health insurance or reimbursement schemes in the mainland of China, Australia, Singapore and South Korea.

The ASEAN region, with its steady economic growth and a population exceeding 600 million, has become a significant potential market for global biomedical development. The accelerating aging population in ASEAN has increased the overall disease burden on patients and local communities, leading to a growing demand for novel therapeutics. Fulfilling its commitment to enhancing the health and well-being of the ASEAN population, Antengene has successfully obtained NDA approvals for XPOVIO^® in Malaysia in August and very recently in Thailand, and expects XPOVIO^® to be approved in Indonesia in the second half of 2024. Looking ahead, the company aims to introduce more innovative medicines to the ASEAN market, bringing improved healthcare to more patients in the region.

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]).
