复宏汉霖创新抗PD-L1×TIGIT双抗 在澳大利亚完成首例患者用药
T组织免役球蛋白酶酶和ITIM框架域（T cell immunoglobulin and ITIM domain，TIGIT）一种缓和性感觉，在腮腺组织中展示，有自动攻击（NK）组织、滋养的CD8+ T和CD4+ T组织和Treg（调高性T组织）等。是 免役体检点蛋白酶酶，TIGIT可使用四种效用机制化缓和原有和自我调节性免役，在淋巴癌症免役缓和中的“踩剎车”效用和PD-1/PD-L1相似。临床检验前的研究然而显示，差距抗PD-L1单抗、抗TIGIT单抗和多重单抗的联合技术根治方案，HLX301可人与人之间PD-L1和TIGIT炎症因子聊天根据并同一中医PD-1/PD-L1和TIGIT/PVR负向走势径路，缓和淋巴癌症组织的种植，且耐受力性、应急性健康，充足突显了双抗根治方案的携手怎强定律，已成定局使用于四种肺肿瘤肝转移淋巴癌症的根治，有非小组织肺肿瘤、头脖颈鳞状组织癌、食管鳞癌等。到目前为止，各国範圍内还没有同种靶向药物治疗PD-1/L1和TIGIT的双炎症因子聊天表面抗原应用开卖，且HLX301在同种靶向药物治疗PD-L1×TIGIT双炎症因子聊天表面抗原中稳步达成首起受试者施药，已成定局为first-in-class抗PD-L1×TIGIT双抗。
复宏汉霖持续深入未考虑的临床研究需要量，当前已提升出多样化化的多元化发展药备选成品供水管，在PD-1/L1、LAG-3、TIGIT、BRAF等多元化发展靶点逐步构造，并关键做双非特异朋友表面抗原、表面抗原偶联控制药物（ADC）等成品的开发管理。复宏汉霖正关键减速向多元化发展型Biopharma升级，提生多元化发展热效率，大力加强一流多元化发展股权的技术引进和合作共赢，“内外线兼修”，为全球最大患有带去优效果、可承担的多元化发展控制策划方案。

First Subject Dosed in the Australia Phase 1 Trial of Henlius' Potential First-In-Class Anti PD-L1×TIGIT Bispecific Antibody
Shanghai, China, Feburary 14th, 2022-Shanghai Henlius Biotech, Inc. (2696.HK) today announced that the first patient has been dosed in Australia in the Phase 1 clinical trial of HLX301, a recombinant humanized anti-PD-L1 and anti-TIGIT bispecific antibody (BsAb), for the treatment of locally advanced or metastatic solid tumours.
TIGIT (T cell immunoreceptor with immunoglobulin and ITIM domains) is an inhibitory receptor, mainly expressed on natural killer (NK) cells and activated CD8+ T cells, CD4+ T cells, and T regulatory cells. As an inhibitory receptor, TIGIT can inhibit innate and adaptive responses in various mechanisms of action and act as a “brake” like PD-1/PD-L1 does to stop T cells from attacking tumours. Pre-clinical studies reported that HLX301 can simultaneously block both PD-1/PD-L1 and TIGIT/PVR pathways, restore TCR signaling, inhibit tumour growth, and has good tolerance and safety, paving the way for further clinical development to against a variety of advanced cancers, including non-small cell lung cancer, head and neck squamous cell carcinoma, esophageal squamous cell carcinoma, etc. At present, no BsAb targeting PD-1/PD-L1 and TIGIT has been approved for marketing globally. As the first to be dosed in the subject, HLX301 is expected to be a first-in-class anti-PD-L1×TIGIT BsAb.
Underpinned by the patient-centric strategy, Henlius has built an innovative product pipeline with many emerging targets, including PD-1/L1, LAG-3, TIGIT, BRAF, etc. and has been developing a forward-looking presence in bispecific antibodies and the antibody-drug conjugates (ADC). Looking forward, Henlius is actively accelerating the evolution to an innovative Biopharma and improving efficiency through innovations, and will continue its momentum for innovation, further strengthening the in-licensing and collaboration on external innovative assets, and bringing more high-quality and affordable therapies to patients worldwide.
About HLX301 Phase 1 Trial
This open-label, multicentre, dose-finding, first-in-human phase 1 study aims to evaluate the safety, tolerability, pharmacokinetics, and preliminary anti-tumour efficacy of HLX301 in locally advanced or metastatic solid tumour patients who have failed prior standard treatment and are intolerant or ineligible to standard therapy. Eligible patients will receive intravenous infusion of HLX301 as a single agent every- two-week. Phase 1a is a dose escalation study. The primary endpoints are to evaluate the safety, dose limiting toxicity (DLT), and determine the maximum tolerated dose (MTD) of HLX301. Secondary endpoints include pharmacokinetic, pharmacodynamic and immunogenicity. Phase 1b is a dose expansion study. The primary endpoint is to determine the recommended phase 2 dose (RP2D). Secondary endpoints include objective response rate (ORR), disease control rate (DCR), and duration of response (DOR).
