H药小细胞肺癌数据亮眼
国产创新药风采绽放
小细胞肺癌（SCLC）占肺癌总数的15%-20%，是肺癌中侵袭性最强的亚型，分为局限期小细胞肺癌（LS-SCLC）和广泛期小细胞肺癌，二者共同点是恶性程度高、转移早、疾病进展迅速，总体预后不良。免疫检查点抑制剂的出现为ES-SCLC领域的治疗带来新希望。
ASTRUM-005为一项在既往未接受过治疗的ES-SCLC患者中比较H药注射液联合化疗（卡铂-依托泊苷）及安慰剂联合化疗（卡铂-依托泊苷）的临床有效性和安全性的随机、双盲、国际多中心、III期临床研究。该试验在中国、土耳其、欧盟波兰、格鲁吉亚等多个国家共开设128个试验中心，其中114个试验中心有受试者参与了筛选，共入组585例受试者，其中约31.5%为高加索人。2021年12月，公司宣布ASTRUM-005已于中期分析达到主要研究终点总生存期（OS）。研究数据显示，H药联合化疗在总体人群和亚洲人群均可延长OS，显示出良好的疗效和安全性。充分的国际临床试验数据也有望支持H药在欧盟、美国等主流法规市场的申报，为全球临床应用奠定基础。
目前，公司H药针对ES-SCLC的上市注册申请（NDA）已获国家药监局受理，有望成为全球首个一线治疗SCLC的抗PD-1单抗。H药联合化疗近期也被《2022 CSCO小细胞肺癌诊疗指南》推荐作为ES-SCLC一线疗法，是对H药临床疗效及安全性的高度认可。此外，H药用于SCLC治疗也于近期获得美国FDA授予的孤儿药资格认定（Orphan-drug Designation），公司亦计划于2022年在欧盟递交H药针对ES-SCLC适应症的上市注册申请。
差异化MSI-H实体瘤适应症
“不限癌种”免疫治疗新选择
据统计，中国每年新发MSI-H肿瘤患者逾30万，其中部分患者缺乏有效治疗，目前我国鲜有针对MSI-H晚期实体瘤获批的PD-1抑制剂，临床治疗需求远未被满足，H药的获批为众多实体瘤患者带去新的治疗选择。ASTRUM-010为一项针对MSI-H实体瘤的单臂、多中心、关键性II期临床研究，该试验的主要终点为独立影像评估委员会（IRRC）依据RECIST v1.1标准评估的客观缓解率（ORR）。该项临床试验结果曾分别于2021年ASCO年会、2021年CSCO年会上发布，此次ASCO年会上将公布该研究的更新数据。研究结果表明，H药单药治疗既往标准治疗失败的、不可切除或转移性MSI-H实体瘤获益显著，达到预设的主要终点标准，且具有良好的安全性和耐受性。
未来，公司也将继续以患者需求为核心，凭借高效及创新的自主核心能力持续推进更多汉霖“质”造，为中国乃至全球患者提供最高品质的药物和服务，打造生物制药领域民族品牌。

Co-Leading PI: Shukui Qin, Qinhuai Medical Area, Eastern Theater General Hospital of PLA China; Jin Li, Shanghai East Hospital, Tongji University
Form: Poster
Time: June 3, 2022, CDT
• Phase 1 study on solid tumors
Title: A phase 1 study of serplulimab, a novel humanized monoclonal anti-PD-1 antibody, in patients with advanced solid tumors (Abstract No. e14560)
Form: Abstract
Being a breakthrough in SCLC treatment, serplulimab shows the power of Chinese innovation
Small cell lung cancer (SCLC) accounts for 15%–20% of all cases and is the most aggressive type of lung cancer. It is classified into two stages: limited stage (LS-SCLC) and ES-SCLC, with both exhibiting high malignancy, strong invasiveness, early metastasis, fast disease progression, and a poor prognosis. The advent of immune checkpoint inhibitors has been proved to bring hope to patients with ES-SCLC.
ASTRUM-005 is a randomized, double-blind, international, multi-center, phase 3 clinical study that aims to compare the efficacy and safety of HANSIZHUANG with placebo when combined with chemotherapy (carboplatin-etoposide) in previously untreated patients with ES-SCLC. This study has set up a total of 128 sites in China, Turkey, Poland, Georgia, etc. and enrolled 585 subjects from 114 sites, among whom 31.5% were Caucasian. In December 2021, ASTRUM-005 had met its primary study endpoint of the overall survival (OS) in the interim analysis and demonstrated HANSIZHUANG with a manageable safety profile. The global clinical data lays a solid foundation for future applications across the world.
Previously, the NDA of HANSIZHUANG for the treatment of ES-SCLC has been accepted by NMPA. Recently, HANSIZHUANG was recommended by the 2022 CSCO Guidelines for Diagnosis and Treatment of SCLC for the treatment of ES-SCLC, stating the highly recognition for the efficacy and security of HANSIZHUANG. In addition, the FDA has granted orphan drug designation to HANSIZHUANG for treatment of SCLC, and Henlius also plans to file MAA on ES-SCLC in the EU in 2022.
The differentiated MSI-H indication, "Pan-cancer" treatment benefits a broader patient population
It is estimated that there are more than 300,000 new MSI-H tumor cases in China every year, and some patients lack effective treatment. Furthermore, there are few PD-1 inhibitors approved for MSI-H advanced solid tumors in China currently. The clinical treatment demand is far from being met. ASTRUM-010 is a single-arm, multi-center, pivotal phase 2 clinical study. The primary efficacy endpoint was objective response rate (ORR) assessed by independent radiological review committee (IRRC) per RECIST v1.1. This study results have been presented at the 2021 ASCO annual meeting and the 2021 CSCO annual meeting. At 2022 ASCO, we will present its updated data. The study has met its primary endpoint and brought significant benefits to unresectable or metastatic MSI-H solid tumors patients who have failed to respond to previous standard treatments with good safety and tolerability.
In the future, Henlius will keep focusing on patient needs and inspire more "made-by-Henlius" products with efficient and innovative in-house capabilities, aiming to provide highest quality solutions and services for patients in China and across the world and to build a national brand in biopharmaceutical industry.
About HANSIZHUANG
HANSIZHUANG (recombinant humanized anti-PD-1 monoclonal antibody injection, generic name: serplulimab injection) is the first innovative monoclonal antibody developed by Henlius. Up to date, 1 indication is approved for marketing in China, 2 NDAs have been accepted by the NMPA, and 9 clinical trials are ongoing across the world.
HANSIZHUANG was approved by the NMPA for the treatment of MSI-H solid tumors in March 2022 and actively promotes its synergy with in-house products of the company and innovative therapies. It has successively obtained clinical trial licenses in China, the United States, the European Union and other countries and regions to initiate 9 clinical trials on immuno-oncology combination therapies worldwide in a wide variety of indications, such as lung cancer, esophageal carcinoma, head and neck squamous cell carcinoma and gastric cancer, etc., and covering the full range of first-line treatments of lung cancers. As of now, the company has enrolled more than 2,800 subjects in China, Turkey, Poland, Georgia and other countries and regions, and the proportion of Caucasian is over 30% in two MRCTs, making HANSIZHUANG an anti-PD-1 mAb with one of the largest global clinical data pools. The NDAs of the treatment for squamous non-small cell lung cancer (sqNSCLC) and the first-line treatment of extensive small-cell lung cancer (ES-SCLC) have been accepted by the NMPA. Furthermore, HANSIZHUANG was recommended by the 2022 CSCO Guidelines for Diagnosis and Treatment of Small Cell Lung Cancer (SCLC) for the treatment of ES-SCLC and was also granted orphan drug designation by the FDA for treatment of SCLC. The MAA of ES-SCLC is expected to be filed in the EU in 2022, which makes HANSIZHUANG potentially the world’s first anti-PD-1 mAb for the first-line treatment of SCLC. In the field of esophageal squamous cell carcinoma, the phase 3 clinical trial of HANSIZHUANG in combination with chemotherapy has met the co-primary endpoints.
