Phase I Study of Malignancies That Express NY-ESO-1 With T Cell Receptor-transduced T Cells Targeting NY-ESO-1

Background:
Autologous T cells engineered to express a T cell receptor (TCR) targeting NY-ESO-1 will be infused back to patients with NY-ESO-1- expressing malignancies. The patients pretreated with a lymphodepleting preconditioning regimen will be monitored after infusion of anti-NY-ESO-1 TCR-transduced T cells for adverse events, persistence of anti-NY-ESO-1 TCR-transduced T cells and treatment efficacy.
Objectives:
To evaluate the safety and the efficacy of anti-NY-ESO-1 TCR-transduced T cell-based immunotherapy for patients with NY-ESO-1- expressing malignancies.
Eligibility:
Patients older than one year of age, who have relapsed or refractory malignancies that express both NY-ESO-1 and human leukocyte antigen (HLA)-A2 molecules.
Patients must have adequate organ functions.
Design:
Peripheral blood from patients will be collected for isolation of peripheral blood mononuclear cells (PBMCs), which will be transduced with a lentiviral or retroviral vector encoding an HLA-A2 restricted anti-NY-ESO-1 TCR gene.
Patients will receive a lymphodepleting preconditioning regimen to prepare their immune system to accept modified T cells.
Patients will receive an infusion of their own modified T cells. They will remain in the hospital to be monitored for adverse events until they have recovered from the treatment.
Patients will have frequent follow-up visits to monitor the persistence of modified T cells and efficacy of the treatment.

Phase II Study of Metastatic Cancer That Expresses NY-ESO-1 Using Lymphodepleting Conditioning Followed by Infusion of Anti-NY ESO-1 Murine TCR-Gene Engineered Lymphocytes

Background:
The National Cancer Institute (NCI) Surgery Branch has developed an experimental therapy for treating patients with cancer that involves taking white blood cells from the patient, growing them in the laboratory in large numbers, genetically modifying them, and then giving the cells back to the patient. In a previous study the NCI Surgery Branch used the anti-ESO-1 gene and a type of virus (retrovirus) to make these tumor fighting cells (anti-ESO-1 cells). About half of the patients who received this treatment experienced shrinking of their tumors. In this study, we are using a slightly different method of producing the anti-ESO-1 cells which we hope will be better in making the tumors shrink.
Objectives:
The purpose of this study is to see if these tumor fighting cells (genetically modified cells) that express the receptor for the ESO-1 molecule on their surface can cause tumors to shrink and to see if this treatment is safe.
Eligibility:
- Patients 15 years old and older with cancer that has the ESO-1 molecule on their tumors.
Design:
Work up stage: Patients will be seen as an outpatient at the National Institutes of Health (NIH) clinical Center and undergo a history and physical examination, scans, x-rays, lab tests, and other tests as needed
Leukapheresis: If the patients meet all of the requirements for the study they will undergo leukapheresis to obtain white blood cells to make the anti ESO-1 cells. {Leukapheresis is a common procedure which removes only the white blood cells from the patient.}
Treatment: Once their cells have grown the patients will be admitted to the hospital for the conditioning chemotherapy, the anti-ESO-1 cells and aldesleukin. They will stay in the hospital for about 4 weeks for the treatment.
Follow up: Patients will return to the clinic for a physical exam, review of side effects, lab tests, and scans about every 1-3 months for the first year, and then every 6 months to 1 year as long as their tumors are shrinking. Follow up visits take up to 2 days.

NY-ESO-1 is a SEREX-defined cancer-testis antigen of which several MHC I, but only few MHC II-restricted epitopes have been identified. Searching for highly promiscuous MHC II-restricted peptides that might be suitable as a CD4+ stimulating vaccine for many patients, we used the SYFPEITHI algorithm and identified an NY-ESO-1-derived pentadecamer epitope (p134-148) that induced specific CD4+ T-cell responses restricted to the HLA-DRB1 subtypes *0101, *0301, *0401, and *0701 that have a cumulative prevalence of 40% in the Caucasian population. The DR restriction of the p134-148 pentadecamer was demonstrated by inhibition with an HLA-DR antibody and a functional peptide displacement titration assay with the pan-DR-binding T-helper epitope PADRE as the competitor. The natural processing and presentation of this epitope was demonstrated by recognition of an NY-ESO-1+ melanoma cell line by T cells with specificity for p134-148. The pentadecamer p134-148 was able to induce CD4+ responses in 4/38 cancer patients tested. However, no strict correlation was found between CD4+ T-cell responses against p134-148 reactivity and anti-NY-ESO-1 antibody titers in the serum of patients, suggesting that CD4+ and B-cell responses are regulated independently. In conclusion, p134-148 holds promise as a broadly applicable peptide vaccine for patients with NY-ESO-1-positive neoplasms.

治疗实体瘤，这6款细胞疗法入选ASCO口头报告，来自西比曼/阿斯利康、科济药业等公司！

▎药明康德内容团队报道2024年美国临床肿瘤学会（ASCO）年会已于今日（当地时间5月31日）在美国芝加哥正式开幕。根据ASCO官网摘要信息，今年共有5800+项研究入选本届大会，其中有426项研究入选了“口头报告环节（Oral Abstract Session）”和“快速口头报告（Rapid Oral Abstract Session）环节”。梳理这些口头报告研究，我们发现有近20项细胞疗法相关研究入选，包括了CAR-T细胞疗法、TCR-T细胞疗法、TIL疗法、基于细胞的现货型免疫疗法等等。在这其中，多家中国公司的细胞疗法也入选了ASCO大会口头报告，如科济药业Claudin18.2靶向CAR-T、艺妙神州靶向GUCY2C的CAR-T、博生吉CD7靶向CAR-T产品等。我们注意到，入选本次ASCO大会口头报告的细胞疗法中，有至少6项研究针对的适应症为实体瘤，涵盖胃肠道肿瘤、滑膜肉瘤、肝癌、乳腺癌、黑色素瘤等。在细胞治疗领域，实体瘤曾经是一座难以逾越的高峰，而近年来越来越多的新疗法、新技术正在解决这一挑战，并取得临床突破。本文中我们将一起看看针对实体瘤适应症的细胞疗法，看看它们的临床表现如何？注：本表由《医药观澜》根据ASCO官网摘要整理，如有遗漏，欢迎补充。西比曼生物/阿斯利康：C-CAR031作用机制：自体抗GPC3 CAR-T疗法适应症：肝细胞癌C-CAR031是一种针对肝细胞癌的自体抗GPC3的CAR-T疗法。本次入选口头报告的是该产品治疗晚期肝细胞癌（HCC）患者的1期研究结果。GPC3是HCC中过表达的表面抗原，在健康组织中几乎不存在。截至2024年1月5日，共有24例患者接受了4个剂量水平（DLs）的C-CAR031输注。所有患者均可进行安全性评估。未观察到剂量限制性毒性和免疫效应细胞相关神经毒性综合征（ICANS）。22个患者可评估疗效。90.9%的患者肿瘤缩小，肝内病变和肝外病变患者的中位肿瘤缩小率为44.0%（范围为3.4%~94.4%）。所有患者疾病控制率（DCR）为90.9%，客观缓解率（ORR）为50.0%，DL4的ORR为57.1%。该研究显示C-CAR031在接受过重度治疗的晚期HCC患者中具有可控的安全性和增强的抗肿瘤活性。艺妙神州：IM96作用机制：靶向GUCY2C的CAR-T疗法适应症：结直肠癌IM96是一款靶向鸟苷酸环化酶2C（GUCY2C）的CAR-T疗法，本次入选口头报告的是该产品治疗转移性结直肠癌患者的1期研究结果。GUCY2C在结直肠癌的所有阶段均异位表达。截至2023年12月，20名患者入组并注射了IM96，所有患者随访时间为7~19个月。安全性数据显示，只有5%的患者表现出神经毒性和3级细胞因子释放综合征（CRS），研究没有达到剂量限制毒性和最大耐受剂量。19例可评估患者中，DCR为73.7%，ORR为26.3%。DL3组（12×108）患者的ORR为40.0%，与肝转移与否无关。DL3组中位无进展生存期为7个月，中位缓解持续时间为10个月。在所有患者中，肿瘤应答与癌胚抗原水平的显著降低相关。本研究表明，IM96在错配修复完整（pMMR）mCRC患者中具有持久的疗效和可接受的安全性，特别是在肝转移患者中显示出较高的治疗潜力。科济药业：CT041作用机制：靶向Claudin18.2自体CAR-T细胞候选产品适应症：胃肠道肿瘤CT041是一种靶向Claudin18.2蛋白的自体CAR-T细胞候选产品，正在针对晚期胃癌/食管胃结合部腺癌的确证性2期临床试验。本次入选口头报告的是一项治疗胃肠道肿瘤患者的1期临床研究数据。疗效数据显示，所有患者的ORR和DCR分别达到37.8%和75.5%。所有患者的中位无进展生存期（PFS）和中位总生存期（OS）分别为4.4个月和8.4个月。在接受CT041单药治疗的可评估疗效的胃癌患者中，有可测量疾病（n=47）的ORR和DCR分别达到57.4%和83.0%，所有可评估疗效的胃癌患者（n=55）的中位PFS和中位OS分别为5.8个月和9.7个月。研究人员认为，CT041在大量预处理的Claudin18.2阳性晚期GI癌症患者中显示出有希望的安全性和高度令人鼓舞的疗效。Adaptimmune：letetresgene autoleucel（lete-cel）作用机制：靶向NY-ESO-1抗原的TCR-T疗法适应症：滑膜肉瘤或粘液样/圆形细胞脂肪肉瘤Lete-cel为一种靶向NY-ESO-1实体瘤抗原的工程化T细胞受体（TCR）-T细胞疗法。NY-ESO-1通过在HLA-A*02于滑膜肉瘤和黏液样/圆细胞脂肪肉瘤（MRCLS）中高度表达。本次入选口头报告的是一项2期临床研究结果。研究纳入98名滑膜肉瘤和MRCLS患者，45名患者可评估疗效。结果显示，总体ORR为40%（包括2例CR，16例PR），其中滑膜肉瘤和MRCLS患者的ORR分别为39%和41%。中位反应持续时间为10.6个月。在该研究中，不良事件与先前观察到的一致。研究人员认为，该研究进一步支持了Lete-cel作为晚期滑膜肉瘤和MRCLS疗法的潜力。Obsidian Therapeutics：OBX-115作用机制：靶向IL-15的TIL疗法适应症：黑色素瘤OBX-115是一款保留白细胞介素2（IL2）的工程化肿瘤浸润淋巴细胞（TIL）疗法，该产品使用经FDA批准的小分子药物乙酰唑胺（ACZ）调节膜结合IL15的表达，为TIL的扩增和存续提供细胞因子支持，因此患者在接受该疗法治疗时不需要同时接受高剂量IL2。该产品目前正处于1/2期多中心研究阶段。入选口头报告的是一项1期研究结果，评估了OBX-115方案在ICI耐药、不可切除/转移性黑色素瘤患者中的疗效和安全性。截至2024年1月2日，9名黑色素瘤患者接受了OBX-115输注，他们既往治疗的中位线为3。在至少12周随访的患者中（n=6），按RECIST v1.1计算的ORR为50%（2例CR，1例PR，3例SD）；所有反应都发生在第6~18周之间，最长反应持续时间>12个月。研究人员认为，OBX-115治疗耐受性良好，产生持续加深和持久的反应，表明其可能介导无大剂量IL2的ICI耐药转移性黑色素瘤的完全缓解和持久的临床益处。BriaCell公司：Bria-IMT（SV-BR-1-GM）作用机制：基于细胞的靶向免疫疗法适应症：乳腺癌Bria-IMT方案是一种基于异体全细胞免疫疗法，可刺激患者的免疫系统诱导靶向杀死癌细胞。根据ASCO官网介绍，经皮内照射Bria-IMT的乳腺癌细胞会分泌GM-CSF，并在HLA-I和II分子上呈递肿瘤相关抗原（TAAs），直接刺激抗肿瘤免疫。PD-1免疫检查点抑制剂（CPI）进一步刺激T细胞并与SV-BR-1-GM协同作用。入选口头报告的是评估该产品结合CPI，治疗既往经过多次治疗（包括ADC和CPI治疗失败）的晚期/转移性乳腺癌的疗效和安全性。共有54例患者接受治疗，结果显示Bria-IMT方案耐受性良好，仅9%因AE退出。在接受SV-BR-1-GM III期制剂治疗的患者中（n=23，结果可评估），ORR为13%，DCR为61%，中位PFS和OS分别为4.1个月和13.3个月。研究结果显示，BRIA-IMT已显示出良好的安全性，同时为重度治疗的晚期/转移性乳腺癌患者提供益处。这项2期研究也为正在进行的3期临床研究提供了依据。值得一提的是，今年1月，BriaCell公司宣布Bria-IMT在伴有中枢神经系统（CNS）转移的晚期乳腺癌患者中达成71%的颅内客观缓解率（iORR）。目前该疗法的的关键3期试验正在进行中。除了上述产品，还有一些其它的细胞疗法入选了本届ASCO大会口头报告，用于治疗不同类型的血液肿瘤（见下表），限于篇幅，此处不再一一介绍。如欲获取本届ASCO大会口头报告的细胞疗法管线和临床试验数据，请扫描下方二维码下载表格查看。相关阅读：2024年ASCO口头报告ADC研发管线一览参考资料：[1]ASCO大会官网.
