这是继复发/难治性多发性骨髓瘤（R/R MM）之后，希维奥在中国获批的第二项适应症，用于单药治疗复发/难治性弥漫性大B细胞淋巴瘤（R/R DLBCL）成人患者。
中国注册性临床试验SEARCH研究的试验数据显示，60例接受治疗的中国受试者的总体缓解率（ORR）达到试验预设的主要终点。
希维奥是一种全新机制的口服药物，公司正在开发希维奥在骨髓纤维化（MF）、T细胞非霍奇金淋巴瘤（T-NHL）和内膜癌等不同疾病领域的多种联合疗法。
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。产品还在泰国、马来西亚和印尼等多个东盟市场提交了新药上市申请（NDA），并预计于今年下半年陆续获批。
中国上海和香港，2024年7月5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，希维奥（塞利尼索片）的新适应症正式获得国家药品监督管理局（NMPA）批准，用于单药治疗复发或难治性弥漫性大B细胞淋巴瘤（R/R DLBCL）成人患者。
打破复发难治治疗窘境
DLBCL治疗新利器
DLBCL是成人非霍奇金淋巴瘤（NHL）中最常见的一种类型，并且是一种在临床表现和预后等多方面具有很大异质性的恶性肿瘤。DLBCL患者若采用目前标准免疫化疗方案，5年无进展生存率可达60-65%，40-50%患者可以获得治愈，但仍然有约10%-15%患者对一线标准方案原发难治，20-25%患者缓解后疾病复发，这部分患者预后非常差，亟需新药满足治疗需求。
经临床验证疗效显著
口服便利惠及广大患者
这项新适应症的获批是基于一项中国注册性临床试验SEARCH研究的数据支持。该研究共入组60例中国DLBCL患者，所有受试者由中心放射影像实验室评估的总体缓解率（ORR）达到试验预设的主要终点。研究结果表明，希维奥单药口服在中国受试者中具有明确的临床疗效，包括显著的缓解率、持久的缓解时间和生存期。

“DLBCL是成人NHL最常见类型，在中国约占NHL的40%，且发病率正逐年递增，三线及以上复发或难治性患者缺少有效便捷的治疗方案。塞利尼索作为全新机制的核输出蛋白抑制剂，以独特的机制（MOA），疗效明确，用药便利，可自行在家口服，减轻住院负担和费用，为中国患者提供了一种新的治疗选择。新适应症的获批对中国R/R DLBCL患者意义重大。”
全球40多国获批上市
逐步实现亚太医保覆盖
希维奥是全球首个全新机制的口服选择性XPO1抑制剂，已在全球40多个国家和地区获批上市。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。公司还在泰国、马来西亚和印度尼西亚等多个东盟市场提交了希维奥的NDA，这些申请预计将于2024年下半年获得批准。
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。

XPOVIO (selinexor) Approved for New Indication in DLBCL in China, Bringing a New Treatment Option to Patients in the Country
- Following its initial approval for the treatment of relapsed/refractory multiple myeloma (R/R MM), XPOVIO has now received approval as a monotherapy for the treatment of adult patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) marking the second approved indication of XPOVIO in China.
- Results from the registrational SEARCH study in China showed that the overall response rate (ORR) among the 60 Chinese patients treated with XPOVIO met the study’s prespecified primary endpoint.
- XPOVIO is an oral drug with a novel mechanism of action. Antengene is currently developing multiple combination regimens of XPOVIO for the treatment of various indications including myelofibrosis (MF), T-cell non-Hodgkin's lymphoma (T-NHL), and endometrial cancer.
- XPOVIO has been approved for health insurance coverage in the mainland of China, Australia, Singapore and South Korea. Furthermore, Antengene has submitted new drug applications (NDAs) for XPOVIO in other ASEAN markets including Thailand, Malaysia and Indonesia. Approvals in these markets are anticipated in the second half of 2024.
Shanghai and Hong Kong, PRC, July 5, 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 China National Medical Products Administration (NMPA) has approved a new indication of XPOVIO (selinexor) as a monotherapy for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL).
A Novel Therapy Bringing Long-awaited Clinical Breakthrough to the Treatment of R/R DLBCL
DLBCL is one of the most common subtypes of non-Hodgkin lymphoma (NHL) in adults and is highly heterogeneous malignancy in both clinical manifestations and prognosis. The current standard treatment, immunotherapy, offers patients with DLBCL a five-year progression-free survival rate of 60%-65% and curative outcomes for 40%-50% of treated patients. However, 10%-15% of DLBCL patients do not respond to standard first-line treatment, and 20%-25% experience relapses after achieving initial responses, leading to a poor prognosis and enormous unmet clinical needs.
The Clinically Validated Efficacy and Convenience of Oral Administration of Selinexor Offer Benefits to a Broad Spectrum of Patients
The approval for the new indication was supported by data from the registrational SEARCH study in China. Results from the study, which enrolled a total of 60 Chinese patients with DLBCL, showed that patients treated in the trial achieved a central radiological review assessed overall response rate (ORR) meeting the pre-specified primary endpoint. The SEARCH study demonstrated clear efficacy of orally-administered selinexor monotherapy in Chinese patients, exhibiting significant response rates, durable responses, long survival.
Prof. Jun Zhu, principal investigator of the SEARCH study from Peking University affiliated Beijing Cancer Hospital, said, “DLBCL is the most common subtype of NHL in adults and accounts for 40% of all NHL cases in China. The incidence of NHL has been steadily rising year over year, while patients with third- and later-lines relapsed or refractory disease lack effective and convenient therapies. As a nuclear export protein inhibitor with a novel mechanism of action (MOA), selinexor offers patients a new treatment option that is efficacious and easy to use, with oral availability that can reduce hospitalization and financial burden on patients by allowing them to receive treatment at home. Overall, the approval for this new indication of selinexor is indeed a great news for Chinese patients with R/R DLBCL.”
Approved in 40+ Markets Globally with Expanding Insurance Coverage Across APAC
With a novel mechanism of action, XPOVIO is the world’s first approved orally-available, selective XPO1 inhibitor. XPOVIO has a global commercial presence with approvals in over 40 countries and regions. To date, XPOVIO has already been included for health insurance coverage in the mainland of China, Australia, Singapore and South Korea. Antengene has also submitted the NDAs in additional ASEAN markets, including Thailand, Malaysia and Indonesia, where approvals are expected in the H2 of 2024.
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]).
