復宏漢霖免疫檢查點抑制劑又添新成員，創新型抗LAG-3單抗IND申請獲NMPA批准
2021年4月15日，複宏漢霖（2696.HK）宣佈，公司自主開發的HLX26（重組抗LAG-3人源化單克隆抗躰注射液）的臨床試驗申請獲得國家藥品監督管理局（NMPA）準予，有望用於實體瘤及淋巴瘤的治療。
淋巴細胞活化基因3（Lymphocyte-activation gene 3，LAG-3）是一種免疫檢查點受體蛋白，被視為繼PD-1/L1、CTLA-4後新一代的免疫治療靶點，全球現時暫無該靶點產品上市。 多項臨床研究資料顯示，LAG-3抑制劑在肺癌、乳腺癌、黑色素瘤和頭頸癌等多種實體瘤和血液腫瘤中均有明顯的疾病控制效果，已有III期臨床研究顯示其與PD-1抑制劑聯用可協同增强免疫應答，具有廣闊的腫瘤治療應用前景。
LAG-3主要在活化的T細胞和部分NK細胞等人體免疫細胞表面表達，與配體結合後，對T細胞的增殖、活化和穩態等起負調節作用-1。 HLX26作為靶向LAG-3胞外結構域的人源化單抗，可阻斷LAG-3介導的負訊號通路，使T細胞重新獲得細胞毒性活性，從而恢復對腫瘤的殺傷功能。 臨床前研究表明，HLX26具有抗腫瘤活性以及良好的耐受性和安全性，尤其是在體外實驗和動物模型中，HLX26與公司創新型PD-1抑制劑HLX10聯用顯示出了明顯的腫瘤抑制作用，具有協同效應。 臨床前研究結果為HLX26後續開展臨床試驗提供了科學依據，該產品有望在實體瘤和淋巴瘤治療領域發揮重要作用，拓展公司疾病治療領域。
現時，複宏漢霖已在PD-1/L1、CTLA-4、LAG-3等免疫檢查點全面佈局，為免疫聯合治療的探索創造更多可能。 未來公司將依託豐富的靶點開發經驗和一體化研發平臺，積極開發更多被市場所需要的創新型產品，打造出高品質、可負擔且具有差异化優勢的創新產品管線。 报错 笔记

Henlius Received IND Approval for Its Novel Anti-LAG-3 mAb HLX26 from NMPA
Shanghai, China, April 15, 2021 – Shanghai Henlius Biotech, Inc. (2696.HK) announced that the investigational new drug (IND) application of its HLX26 (recombinant anti-LAG-3 human monoclonal antibody injection) has been approved by the National Medical Products Administration (NMPA) for treatment of solid tumors and lymphomas.
Lymphocyte-activation gene 3 (LAG-3) is an immune checkpoint receptor and is regarded as a new generation of immunotherapy target after PD-1/L1 and CTLA-4. Currently, there is no LAG-3 targeted product on the market around the globe. A number of clinical studies have shown that LAG-3 inhibitors have obvious disease control effects in many solid tumors and hematological malignancy such as lung cancer, breast cancer, melanoma, head and neck cancer. A Phase III clinical study suggests that targeting the LAG-3 pathway in the combination with PD-1/L1 pathway effectively activates immune response, demonstrating the promising prospect of this product.
LAG-3 is an immune checkpoint receptor that is mainly expressed on human immune cells including activated T cells and part of NK cells, and negatively regulats the proliferation, activization and homeostasis of T cells-1. HLX26 is a human mAb targeting LAG-3 extracellular domains, can block the LAG-3-mediated signaling pathway to restore the killing function of T-cell. Pre-clinical studies have proved that HLX26 has anti-tumor effect and favourable tolerability and safety. Particular in in vitro and animal model studies, HLX26 combined with Henlius’ proprietary anti-PD-1 mAb HLX10 creates synergistic effects in anti-tumor. These results lay the foundation for further clinical studies. HLX26 is expected to play an important role in the treatment of solid tumors and lymphomas, and expand the Company’s therapeutic area.
At present, Henlius has built an all-round layout of the immune checkpoint products of PD-1/L1, CTLA-4 and LAG-3, etc., creating more opportunities for the exploration of combination immunotherapy. Looking forward, the Company will rely on extensive target development experience and integrated R&D platform actively developing more innovative products for patients, and build a high-quality, affordable and differentiated innovative product pipeline.
