Core Insights - AstraZeneca's durvalumab (brand name: Imfinzi) has been approved for a new indication in China, becoming the first and only immunotherapy for the treatment of limited-stage small cell lung cancer (LS-SCLC) in adult patients who have not experienced disease progression after platinum-based chemoradiotherapy [1][2] - The approval is based on positive results from the ADRIATIC Phase III clinical trial, which demonstrated significant overall survival benefits, with a three-year overall survival rate of 57% for patients treated with durvalumab [1] - The trial results were published in a top-tier medical journal and presented at a major oncology conference, confirming the efficacy of durvalumab in the Chinese patient population [1][2] Group 1 - The ADRIATIC trial showed that the median progression-free survival for the durvalumab treatment group was 16.6 months compared to 9.2 months for the placebo group [1] - 46% of patients receiving durvalumab did not experience disease progression at two years, compared to 34% in the placebo group [1] - The Chinese cohort's overall survival and progression-free survival benefits were consistent with global study results, indicating a 29% reduction in the risk of death and a 33% reduction in the risk of disease progression or death compared to placebo [1][2] Group 2 - Approximately 34,000 patients in China are treated for limited-stage small cell lung cancer each year, with a poor prognosis where only 15%-30% survive beyond five years [2] - The approval of durvalumab marks a significant advancement in treatment options for LS-SCLC, which has seen little progress in recent decades [2] - Durvalumab has also been approved in the US, EU, and Japan for the same indication, and it is approved for use in combination with chemotherapy for extensive-stage small cell lung cancer based on the CASPIAN Phase III trial [3]

Core Viewpoint - AstraZeneca is currently facing two significant investigations in China regarding illegal drug imports and the infringement of personal information, which could lead to substantial financial penalties and reputational damage [1][2][4]. Group 1: Illegal Drug Import Investigation - AstraZeneca has received a notice from the Shenzhen Customs Anti-Smuggling Bureau indicating that the company is suspected of evading import taxes amounting to over $1.6 million [1]. - The drug involved in this case is Enhertu (deruxtecan), which was approved for sale in China in February 2023 [1]. - If found liable, AstraZeneca could face fines ranging from one to five times the unpaid import taxes [1].

Group 4: Executive Investigation and Company Actions - The ongoing investigations are linked to the detention of Wang Lei, AstraZeneca's Global Executive Vice President and China President, who is cooperating with the investigation [5][6]. - The investigations are said to focus on individuals rather than the company as a whole, and are not related to previous insurance fraud cases [6]. - AstraZeneca has made significant investments in China, including a $2.5 billion plan to establish a new global strategic R&D center in Beijing [7].

新京报讯（记者王卡拉）日前在法国巴黎举行的欧洲肺癌大会（ELCC）上，吉林省癌症中心主任程颖 教授公布了度伐利尤单抗（商品名：英飞凡）治疗同步放化疗后疾病无进展的局限期小细胞肺癌在 ADRIATIC三期临床试验中国队列研究数据，数据显示，与安慰剂相比，患者在两个主要研究终点总生 存期（OS）和无进展生存期（PFS）的获益趋势与全球患者一致。 小细胞肺癌是一种高侵袭性的肺癌类型。Ⅰ-Ⅲ期的局限期小细胞肺癌约占小细胞肺癌的30%。尽管局 限期小细胞肺癌患者对初始化疗和放疗有应答，但仍会复发并且进展迅速 。局限期小细胞肺癌患者预 后极差，只有15%-30%的患者在确诊后可活过5年。 基于ADRIATIC的试验结果，度伐利尤单抗已在美国、欧洲和一些其他国家获批。目前，中国、日本及 其他多个国家与地区的监管机构正在进行相关审评。 在全球530例随机受试者中，95例（17.9%）为中国人群。中国队列的数据显示：与安慰剂相比，度伐 利尤单抗可降低死亡风险29%，两组患者的中位OS均未达到；度伐利尤单抗单药治疗和安慰剂治疗的 三年生存率预估分别为63.7%和55.4%；度伐利尤单抗还将疾病进展或死亡风险降低了33%。度伐利尤 ...
