复宏汉霖达雷妥尤单抗类似药正式获批临床

2021年1月13日,复宏汉霖(香港联交所代码:2696.HK)宣布,国家药品监督管理局(NMPA)正式批准了公司自主开发的达雷妥尤单抗生物类似药HLX15(重组抗CD38全人单克隆抗体注射液)的临床试验申请,用于多发性骨髓瘤(MM)的治疗。

HLX15是复宏汉霖自主开发的一款全人源抗CD38 IgG1κ单克隆抗体。一方面,HLX15可直接与肿瘤细胞表面表达的CD38结合,通过补体依赖的细胞毒作用(CDC)、抗体依赖的细胞毒作用(ADCC)、抗体依赖的细胞吞噬作用(ADCP)、以及Fc介导的交联作用等多重反应诱导骨髓瘤细胞凋亡和溶解,达到快速缓解;此外,HLX15还可通过降低髓源性抑制细胞和消耗CD38表达阳性的免疫调节性T、B细胞来调节免疫微环境,增强免疫系统对肿瘤细胞的抑制作用。参照NMPA发布的《生物类似药研发与评价技术指导原则(试行)》和EMA发布的Guideline on Similar Biological Medicinal Products的要求,复宏汉霖采用逐步递进、比对及相似性评价原则,对HLX15与原研达雷妥尤单抗进行了头对头的药学分析和体内外药理学比对研究。研究结果显示,HLX15和原研达雷妥尤单抗具有高度相似性。

多发性骨髓瘤是血液系统中第二大类常见恶性肿瘤,约占血液系统恶性肿瘤的10% [1]。研究发现,CD38在大量恶性血液癌症特别是多发性骨髓瘤等癌症中高度表达,被认为是多发性骨髓瘤治疗性抗体药物的理想开发靶点[2-3]达雷妥尤单抗是全球首个获批上市的靶向作用于CD38的单克隆抗体,目前该药已在中国获批单药治疗复发和难治性多发性骨髓瘤成年患者,其多种联合疗法亦已在全球获批用于多发性骨髓瘤患者的一线、二线及以上治疗。根据IQVIA数据统计,2019年度达雷妥尤单抗于全球范围内的销售额超过28亿美元,市场需求巨大。
2019年,复宏汉霖成功推出中国首个生物类似药汉利康®,用于非霍奇金淋巴瘤和慢性淋巴细胞白血病的治疗至此,HLX15成为复宏汉霖又一款自主开发的血液肿瘤治疗产品,进一步拓展了复宏汉霖丰富的产品管线。同时, HLX15的开发有望缓解患者的经济负担,为国内多发性骨髓瘤患者,尤其是复发和难治性患者带来优质的治疗新选择。在持续推进生物类似药产品开发的同时,复宏汉霖也将不断拓展公司创新产品管线,凭借已经建立起的完善的创新研发平台,持续高效地为全球患者提供可负担的、疗效更好的治疗方案。

Henlius Daratumumab Biosimilar Received IND Approval from NMPA
Shanghai, China, Jan, 13th, 2021 – Shanghai Henlius Biotech, Inc. (2696.HK) announced that the Investigational New Drug (IND) application of the Company’s daratumumab biosimilar HLX15, a recombinant anti-CD38 fully human monoclonal antibody injection, for the treatment of multiple myeloma (MM) has been approved by the National Medical Products Administration (NMPA).
HLX15 is a fully human anti-CD38 IgG1κ monoclonal antibody independently developed by Henlius. On one hand, HLX15 can directly bind to CD38 expressed on the surface of tumor cells, inducing tumor cell lysis and apoptosis through complement-dependent cytotoxicity (CDC), antibody-dependent cell-mediated cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP), and several other pathways such as Fc mediated cross linking to achieve a quick response of tumor cells. In addition, HLX15 can also reduce multiple myeloma cells by reducing myeloid-derived suppressor cells and depleting CD38-positive immunomodulatory T and B cells. In accordance with the Technical Guidelines of Development and Evaluation of Biosimilar Drugs and EMA Guideline on Similar Biological Medicinal Products, HLX15 has been developed strictly following the principles of stepwise development, comparability and similarity assessment and has been compared head to head with reference daratumumab via analytical studies and preclinical studies. The results of these studies showed that HLX15 is highly similar to reference daratumumab.
Multiple Myeloma is the second most common hematologic malignancies and accounts for approximately 10% of hematologic malignant cases[1]. High expression of CD38 is present in varied of hematologic malignancies and all stages along disease progression of multiple myeloma. Considering the expression profile of CD38, it is thought to be an ideal target for the treatment of multiple myeloma[2-3]. Daratumumab is the first CD38-directed monoclonal antibody approved globally and has been approved for the single-agent treatment of adult patients with recurrent and refractory multiple myeloma by NMPA. Its combinations have also been approved for the treatment of first-line, second-line and above multiple myeloma patients globally. According to estimates from IQVIA, total sales of daratumumab worldwide has reached USD 2.8 billion, indicating a huge medical needs for this drug.
In 2019,Henlius has launched the first domestic monoclonal antibody biosimilar 汉利康® to treat non-Hodgkin’s lymphoma and chronic lymphocytic lleukemia. HLX15 is the second product in the area ofhematologic malignancies developed by Henlius, further extending the Company’s enriched portfolio. Meanwhile, HLX15 has the potential to reduce the financial burden of patients with multiple myeloma and provide them an alternative high-quality treatment option, especially for recurrent and refractory patients. Looking forward, Henlius will continue expanding the well-established biosimilar products pipeline and promoting the development of innovative biologics. On the basis of its established and integrated innovation platform, the Company will underscore its long-term commitment to providing affordable and effective therapies for patients worldwide.
