PG国际创新型抗EGFR单抗pimurutamab晚期皮肤鳞状细胞癌II期钻研了局颁发于Therapeutic Advances in Medical Oncology

2026-09-11

近日,PG国际自主研发的沉组抗EGFR单克隆抗体pimurutamab (HLX07),针对部门晚期及转移性皮肤鳞状细胞癌(CSCC)的II期临床钻研第一部门了局颁发于国际肿瘤专业期刊Therapeutic Advances in Medical Oncology 。钻研了局显示,HLX07单药医治晚期CSCC展示出积极的疗效与优良的安全性特点,为在更大的患者人群中进一步索求抗EGFR靶向医治提供了新的循证凭据 。

ORR达60.0%,展示积极抗肿瘤活性

皮肤鳞状细胞癌(CSCC)是常见的皮肤恶性肿瘤之一,约占全数皮肤癌的20%,且全球发病率持续上升1-2 。只管早期患者可通过手术或放疗获得较好预后,但对于无法手术或放疗的部门晚期或转移性患者,其10年生计不及20%,仍存在进一步优化医治规划的临床需要1,3 。


目前,晚期CSCC的系统医治重要蕴含免疫医治、化疗及抗EGFR靶向医治1,4,5 。只管免疫医治已成为沉要医治选择,但仍有无数患者无法获得应答;化疗的疗效证据则较为有限,迄今尚无系统性化疗药物获批用于晚期CSCC 。由于CSCC中EGFR表白宽泛且RAS突变率较低,使得EGFR成为潜在的医治靶点6,7 。然而,既往抗EGFR抗体疗效有限,因而,开发疗效和安全性更优的抗EGFR靶向疗法拥有沉要临床价值 。


HLX07是一款新型全人源抗EGFR单克隆抗体 ;诩韧俅睬凹霸缙诹俅沧暄辛司,HLX07阐发出优良的抗肿瘤活性和安全性,并拥有较长的半衰期,支持每3周一次给药 。本次颁发的II期钻研进一步索求了HLX07单药医治部门晚期及转移性CSCC的疗效与安全性 。


该钻研是一项评估HLX07单药在晚期CSCC患者中疗效与安全性的盛开、多中心、两部门II期临床试验 。本次报路第一部门的了局 。钻研入组了伴有淋趋附转移或远端转移的晚期CSCC或无法进行手术/无法进行根治性放疗的部门晚期CSCC患者 。截至2024年4月30日,共入组31例患者,绝大无数患有转移性CSCC,其中1500 mg组(A组)21例、1000 mg组(B组)10例 。B组中60%的患者既往接受过系统性抗肿瘤医治 。钻研重要终点为盲态独立中心审查委员会(BICR)评估的客观缓解率(ORR),次要终点蕴含无进展生计期(PFS)、总生计期(OS)、缓解持续功夫(DOR)、疾病节造率(DCR)、至缓解功夫以及安全性、药代动力学、免疫原性和生涯质量等,并索求疗效与肿瘤EGFR及PD-L1表白水平之间的有关性 。


持久随访数据展示出优异的抗肿瘤活性与生计获益:基于BICR评估,A组中,经确认的ORR为19.0%,均为部门缓解(PR);B组中经确认的ORR达到60.0%,其中蕴含1例齐全缓解(CR) 。DCR别离为61.9%和100% 。A组和B组的PFS别离为4.9个月和7.9个月,DOR别离为5.0个月和7.4个月,OS别离为11.8个月和未达到 。

优良耐受性与安全性,索求最佳给药剂量

HLX07单药安全性可控,未发现新的安全性信号 。钻研支持1000 mg作为HLX07进一步临床评价的剂量水平,后续钻研也将进一步验证其在晚期CSCC患者中的临床获益,并索求EGFR蛋白表白与医治获益之间的关系 。

聚焦未满足临床需要,索求更多肿瘤医治可能

EGFR在多种实体瘤中普遍高表白,蕴含非鳞状和鳞状非幼细胞肺癌,被以为是肿瘤产生、进展及耐药的沉要驱动成分8 。值妥贴心的是,EGFR高表白与EGFR敏感突变并不等同,二者之间的有关性较低9 。尤其在sqNSCLC人群中,经典敏感性EGFR突调换为罕见10 。这意味着,无数EGFR高表白的鳞癌患者并不携带敏感性EGFR突变,因而难以从EGFR-TKI类靶向药中获益10 。只管近年来,抗EGFR单抗结合化疗在肺鳞癌等疾病的医治中展示出肯定的临床获益基础11,12,以PD-1/PD-L1抑造剂为基础的免疫结合化疗也显著改善了晚期肺鳞癌的一线医治终局,但整体疗效仍有提升空间,临床上仍亟需新的结合医治战术13-23 。


从单药医治到结合免疫医治、化疗及ADC,HLX07正通过多元结合战术进一步索求其在EGFR高表白实体瘤中的医治潜力 。 目前,HLX07结合抗PD-1单抗H药 汉斯状?(斯鲁利单抗,欧洲商品名:Hetronifly?)及化疗一线医治晚期鳞状非幼细胞肺癌(sqNSCLC)患者的II/III期临床钻研已在中国实现首例患者给药,并在澳大利亚实现临床试验登记(CTN) 。此表,公司自主研发的创新型法式性殒命配体1(PD-L1)抗体偶联药物(ADC)HLX43结合HLX07医治晚期/转移性实体瘤的Ib/II期临床钻研已获中国国度药品监督治理局(NMPA)核准 。


未来,PG国际将持续秉持“以患者为中心”的初心和理想,通过不休挖掘患者未满足的临床需要,持续夯实更多创新分子的差距化布局,为更多肿瘤患者带来高质量、可职守的新型医治规划 。
