BACKGROUNDAntibody-drug conjugates (ADCs) are an emerging class of targeted therapeutics and are receiving growing attention in the pharmaceutical field. Here we aimed to validate two ligand binding assays for the quantitation of GQ1001, an ADC made of Trastuzumab site-specifically conjugated with DM1, in cynomolgus monkey serum, and then apply the validated assays to a nonclinical study.METHODSThe quantitative methods for conjugated GQ1001 and total GQ1001 were validated against regulatory guidance documents on bioanalytical method validation under a Good Laboratory Practice (GLP)-compliant environment. The validated assays were applied to a single-dose pharmacokinetic (PK) study of GQ1001 conducted in cynomolgus monkeys.RESULTSBoth intra- and inter-assay precision and accuracy met the priori-defined acceptance criteria. Neither matrix effect nor hemolysis effect were observed, and the impact of specific interferents on the assays was evaluated. Dilution linearity was good with the expected dilution factors and no hook effect till up to 20.2 mg/mL of GQ1001 was noted. Besides, the stability of the ADC in monkey serum was found to be sufficient to cover the time required for sample storage and analysis. Furthermore, the assays demonstrated good parallelism determined with a study sample and good reproducibility acquired by incurred sample reanalysis (ISR). Using the validated assays, we obtained serum concentrations for the conjugated GQ1001 and the total GQ1001 in the single-dose PK study, and thereafter, evaluated their exposures over the dosing period.CONCLUSIONSAll tested performance parameters of the assays met the validation acceptance criteria, which supported the application of the two assays in the nonclinical PK study and allowed the evaluation of the related PK parameters for GQ1001.

Antibody-Drug Conjugates Targeting the Human Epidermal Growth Factor Receptor Family in Cancers

3区 · 生物学

ReviewOA

作者: Liu, Xue ; Yu, Jinfeng ; Cai, Xiaoqing ; Fang, Tong ; Yun, Chengyu

Members of the human epidermal growth factor receptor (HER) family, which includes HER1 (also known as EGFR), HER2, HER3 and HER4, have played a central role in regulating cell proliferation, survival, differentiation and migration. The overexpression of the HER family has been recognized as one of the most common cellular dysregulation associated with a wide variety of tumor types. Antibody-drug conjugates (ADCs) represent a new and promising class of anticancer therapeutics that combine the cancer specificity of antibodies with cytotoxicity of chemotherapeutic drugs. Two HER2-directed ADCs, trastuzumane-emtansine (T-DM1) and trastuzumab-deruxtecan (DS-8201a), have been approved for HER2-positive metastatic breast cancer by the U.S. Food and Drug Administration (FDA) in 2013 and 2019, respectively. A third HER2-directed ADC, disitamab vedotin (RC48), has been approved for locally advanced or metastatic gastric or gastroesophageal junction cancer by the NMPA (National Medical Products Administration) of China in 2021. A total of 11 ADCs that target HER family receptors (EGFR, HER2 or HER3) are currently under clinical trials. In this review article, we summarize the three approved ADCs (T-DM1, DS-8201a and RC48), together with the investigational EGFR-directed ADCs (ABT-414, MRG003 and M1231), HER2-directed ADCs (SYD985, ARX-788, A166, MRG002, ALT-P7, GQ1001 and SBT6050) and HER3-directed ADC (U3-1402). Lastly, we discuss the major challenges associated with the development of ADCs, and highlight the possible future directions to tackle these challenges.

BACKGROUNDA novel anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugate (ADC) GQ1001 was assessed in patients with previously treated HER2 positive advanced solid tumors in a global multi-center phase Ia dose escalation trial.METHODSIn this phase Ia trial, a modified 3 + 3 study design was adopted during dose escalation phase. Eligible patients were enrolled, and GQ1001 monotherapy was administered intravenously every 3 weeks. The starting dose was 1.2 mg/kg, followed by 2.4, 3.6, 4.8, 6.0, 7.2 and 8.4 mg/kg. Extra patients were enrolled into 6.0, 7.2, and 8.4 mg/kg cohorts as dose expansion phase. The primary endpoints were safety and to determine the maximum tolerated dose (MTD) based on dose limiting toxicities (DLTs). Pharmacokinetics and anti-tumor efficacy of GQ1001 were assessed. The plasma concentration of free DM1, the payload of GQ1001, was quantitated.RESULTSA total of 32 patients were enrolled, predominantly in breast (9), gastric or gastro-esophageal junction (9) and salivary gland cancer (4). Median number of prior-line of therapies was 3 (0-11) and 37.5% patients received ≥ 2 lines of anti-HER2 therapies. No DLT was observed during dose escalation. MTD was not reached and dose recommended for dose expansion (DRDE) was determined as 8.4 mg/kg. Grade ≥ 3 treatment-related adverse events rate was 28.1% (9/32) and platelet count decreased (4/32, 12.5%) was the most common one. No drug-related death was observed. Objective response rate and disease control rate of 15 evaluable patients in 7.2 mg/kg and 8.4 mg/kg cohorts were 40.0% (6/15) and 60.0% (9/15). Pharmacokinetics analysis showed low exposure and accumulation of free DM1 in circulation.CONCLUSIONGQ1001 is well tolerated and shows promising efficacy in previously treated HER2-positive advanced solid tumors. DRDE was determined as 8.4 mg/kg for following trials. Trial registration NCT, NCT04450732, Registered 23 June 2020, https://clinicaltrials.gov/study/NCT04450732.

SABCS中国之声丨王碧芸教授：GQ1001联合吡咯替尼治疗既往接受过治疗的HER2+MBC药代动力学特征和初步疗效

编者按：HER2阳性乳腺癌的治疗一直是临床研究的热点。2024年SABCS大会上，复旦大学附属肿瘤医院王碧芸教授团队开展的新型HER2 ADC药物GQ1001与吡咯替尼联合应用，治疗既往经治的HER2阳性转移性乳腺癌患者的1b期研究结果公布（摘要号：P5-05-02）。该研究不仅评估了联合用药的药代动力学特征，还初步探讨了其临床疗效，本文特进行介绍。研究背景 GQ1001是一种创新的抗HER2抗体偶联药物（ADC），通过一种新颖、集成且稳定的酶偶联技术，将微管蛋白抑制剂（DM1）与经过工程改造的曲妥珠单抗相连接，其药物抗体比为2[1]。临床前研究表明，GQ1001在多种HER2阳性的患者来源异种移植（PDX）和细胞系来源异种移植（CDX）模型中展现出强大的抗肿瘤活性，并且在大鼠和食蟹猴中表现出优异的药代动力学特性和安全性特征。 Figure 1. The Structure and Characterize of GQ1001 GQ1001单药治疗HER2阳性晚期实体瘤的临床研究（NCT04450732）显示，GQ1001单药在经治的患者中具有优异的耐受性和有前景的抗肿瘤疗效[2]。体内研究还表明，GQ1001与吡咯替尼（一种不可逆的泛HER2受体酪氨酸激酶抑制剂）联合使用时，展现出协同抗肿瘤疗效[1]。因此，我们设计了一项1b期研究（NCT05575804），以探究GQ1001与吡咯替尼联用在经治HER2阳性转移性乳腺癌患者中的安全性和初步疗效。研究方法患者入组标准：经病理学确诊为HER2阳性转移性乳腺癌（MBC）的患者；既往接受过曲妥珠单抗和紫杉烷类药物标准治疗失败的患者；至少有一处可评估的病灶；ECOG为0-1。在“3+3”剂量递增阶段，GQ1001的剂量为6.0 mg/kg、7.2 mg/kg和8.4 mg/kg，每21天为一个周期进行静脉滴注，吡咯替尼以320 mg的固定剂量每日一次口服，每28天为一个周期。剂量递增或递减基于初始剂量组中指定剂量限制性毒性（DLTs）的发生率。在前21天内观察DLTs。主要评估指标：剂量限制性毒性（DLTs）、最大耐受剂量（MTD）或II期推荐剂量（RP2D）、安全性。次要评估指标：客观缓解率（ORR）、疾病控制率（DCR）、缓解持续时间（DOR）、无进展生存期（PFS）、药代动力学（PK）。探索性评估指标：筛选疗效预测分子标志物。 Figure 2. GQ1001-INV-BC-01 Study Design (NCT05575804) 在第1周期和第3周期给药前及给药结束（EOI）后10分钟内采集血液样本用于GQ1001和总抗体（TAb）的检测；在第1天和第8天给药前、给药后4小时和24小时采集血液样本用于吡咯替尼的检测。在给药前、给药结束后10分钟内、给药后0.5小时、2小时、8小时、24小时、48小时、72小时、168小时和336小时采集血液样本用于GQ1001、TAb及fDM1检测。使用酶联免疫吸附测法（ELISA）和液相色谱串联质谱法分别测定血清中GQ1001、TAb和吡咯替尼以及血浆中fDM1的浓度。研究结果共有15例HER2阳性转移性乳腺癌患者接受了GQ1001和吡咯替尼的治疗。所有患者（15/15）既往接受过曲妥珠单抗（或其生物类似物）治疗。33.3%的患者（5/15）既往接受过帕妥珠单抗治疗。本研究剂量递增阶段已完成，且未报告DLT。 Table 1. Demographics and Baseline Characteristics 15例患者的药代动力学数据表明，与既往报道的单药Ia期药代动力学数据相比，GQ1001联合吡咯替尼（320mg，qd）对GQ1001和游离DM1的血药浓度无显著影响。此外，在多次联合给药后，未观察到GQ1001的显著积累。GQ1001+吡咯替尼（320mg，qd）方案下的的吡咯替尼最大血药浓度范围约为103.0 ~ 169.5 μg/mL，与文献报道的吡咯替尼单药治疗的Cmax （143 μg/mL）相当[3]。表明GQ1001与吡咯替尼联用后，GQ1001[5]、DM1[6]和吡咯替尼[4]的血药浓度均未发生显著变化。在数据截止日期（2024年6月30日），中位随访时间为8.61个月（95% CI：6.83-15.08）。10例患者仍在接受治疗，最长治疗持续时间为523天。所有入组患者的12个月无进展生存期（PFS）率为73.5%，ORR为80%（12/15）。在6.0 mg/kg、7.2 mg/kg和8.4 mg/kg剂量水平下，ORR分别为75%（3/4）、100%（5/5）和66.7%（4/6）。未观察到新的不良事件。 Table 2. Summary of Overall Safety Table 3. Clinical Efficacy HER2-positive MBC Figure 3. Best Changess of Target Lesions in Evaluated MBC Figure 4. Treatment Duration and Response in Evaluated MBC 结论药代动力学结果表明，GQ1001和吡咯替尼之间的药物相互作用风险非常低，该联用方案在经治的HER2阳性转移性乳腺癌患者中显示出有前景的初步抗肿瘤活性。研究者说在今年SABCS上，由我们中心发起的GQ1001联用吡咯替尼的IIT研究结果备受关注，吸引了国内外众多专家驻足观看和讨论。GQ1001是启德医药利用iLDC技术平台开发的新一代HER2 ADC，单药的global研究中在多种HER2阳性实体瘤中展现了良好的安全性和有效性。此次我们报道的GQ1001联用吡咯替尼在曲妥珠单抗经治的HER2阳性晚期乳腺癌中的研究，联用的方案取得了很好的效果，安全性较好，没有新增的毒性发生。15例入组患者中，ORR达到80%，其中1例患者CR，4例患者在组超过1年，1例患者在组已接近2年，且在持续获益中。我们也期待能入组更多暴露过Her2-Dxd ADC药物，探索在这类ADC药物耐药人群中的应用，满足未被满足的治疗需求。参考文献上下滑动查看更多内容 [1]、HUANG L, SHI L, SUN Y, et al.
