γδ T 细胞调节小细胞肺癌中的抗肿瘤免疫
γδ T cells modulate anti-tumor immunity in small cell lung cancer.
我们的发现表明,活化的γδ T细胞可能是SCLC治疗的有价值靶点。
英文原题:[18F]F-AraG PET Imaging to Visualize Tumor Infiltrating T-cell Activation in Non-small Cell Lung Cancer.
这是一项分期未标注的注册临床试验,评估细胞治疗用于非小细胞肺癌的安全性、可行性及初步疗效。当前状态:进行中(不再招募)。计划入组 10 例。试验地点:欧洲 · 阿姆斯特丹(共 1 个中心)。登记号:NCT05157659。
不限性别 · ≥ 18 Years
纳入标准: 1. 组织学确诊的NSCLC,必须进行组织学活检。 2. 根据多学科肿瘤委员会评估,患者可 upfront 切除。 3. 愿意并能够为试验提供书面知情同意。 4. 在签署知情同意书之日年龄超过18岁。 5. 筛选时ECOG体能状态评分为0-1。 排除标准: 1. 受试者在筛选前14天内需要接受全身性皮质类固醇(> 10 mg每日泼尼松等效剂量)或其他免疫抑制药物治疗的疾病。在无活动性自身免疫性疾病的情况下,允许使用吸入或局部类固醇,以及肾上腺替代类固醇 >10 mg每日泼尼松等效剂量。 2. 精神或药物滥用障碍,会干扰对试验要求的配合。 3. 患者在试验预计期间内怀孕或哺乳或计划怀孕,从筛选访视开始至最后一次[18F]F-AraG PET扫描后12周。
Inclusion Criteria: 1. Histologically confirmed NSCLC, a histological biopsy is mandatory. 2. Patients that are resectable upfront as per multidisciplinary tumor board evaluation. 3. Be willing and able to provide written informed consent for the trial. 4. Be above 18 years of age on day of signing informed consent. 5. Have a performance status of 0-1 on the ECOG Performance Scale at screening. Exclusion Criteria: 1. Subjects with a condition requiring systemic treatment with either corticosteroids (\> 10 mg daily prednisone equivalent) or other immunosuppressive medications within 14 days of screening. Inhaled or topical steroids, and adrenal replacement steroid \>10 mg daily prednisone equivalent, are permitted in the absence of active autoimmune disease. 2. Psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial. 3. Patient is pregnant or breastfeeding or expecting to conceive within the projected duration of the trial, starting with the screening visit through 12 weeks after the last \[18F\]F-AraG PET scan.

主要终点:Full kinetic modelling · To perform full kinetic modeling of \[18F\]F-AraG for the uptake in tumor lesions and healthy organs (e.g. spleen) by exploring different kinetic models and outcome measures as well as its test-retest (TRT) variability to guide the selection of an optimal PET pharmacokinetic model. · six months;Correlation with number of CD8 T-cell · To correlate the relationship between the tumor uptake of \[18F\]F-AraG and the number of CD8 T-cells amongst others as measured by Immunohistochemistry (IHC) and gene expression. · six months
次要终点:Correlation with [18F]-FDG PET uptake
在切除前一周内将进行两次 [18F]F-AraG PET 扫描。
[18F]F-AraG是一种有前景的示踪剂,可通过正电子发射断层扫描(PET)对活化T细胞进行成像。ATTAIN试验的目的是通过进行完整的动力学建模来研究这种新型示踪剂的药代动力学特征,评估重测(TRT)变异性,并将肿瘤示踪剂摄取与病理评估相关联。
\[18F\]F-AraG is a promising tracer to image activated T-cells with positron emission tomography (PET). The aim of the ATTAIN trial is to investigate the pharmacokinetic characteristics of this novel tracer by performing a full kinetic modelling, assess test-retest (TRT) variability and to correlate the tumor tracer uptake with the pathological assessment.
