中文摘要
背景:免疫治疗推动了癌症治疗的进步,但结局多变以及缺乏稳健的预测性生物标志物限制了其应用。更好的患者选择和合理的联合策略可扩展其有效性。Optim.AI™是一个联合功能精准医学平台,此前已证明可为血液系统癌症和肉瘤鉴定有效的联合治疗。早期版本可指导化疗和靶向治疗的选择,但缺乏免疫组分,限制了所评估的药物。在此,我们评估Optim.AI™ 2.0的临床可行性,该平台将高内涵成像与肿瘤-免疫离体共培养相结合,以预测跨实体瘤和血液系统肿瘤对免疫治疗联合方案的反应。
方法:对于Optim.AI™ 2.0,外周血单个核细胞和肿瘤细胞(非霍奇金淋巴瘤、妇科癌症或胃肠道癌症)经荧光标记以便于细胞追踪。使用适应证特异性的12药物组合对共培养模型进行联合药物处理,包括单克隆抗体、抗体药物偶联物和双特异性抗体。对肿瘤特异性细胞死亡进行高内涵成像分析,用于Optim.AI™ 2.0分析,该分析从155种离体检测组合中衍生出531,441种可能的排列组合进行搜索,以预测性地对药物组合内所有临床可操作的治疗进行排序。将临床相关的免疫治疗与患者特异性因素——疾病分期、亚型和治疗史——进行比较,以评估与预测反应的一致性。
结果:建立了优化的效应细胞与靶细胞比例,以有效量化免疫介导的肿瘤杀伤,包括抗体依赖性细胞毒性。高内涵成像捕捉到肿瘤特异性杀伤及关键的免疫-肿瘤相互作用,如免疫细胞迁移和肿瘤浸润。在多种适应证中,Optim.AI™ 2.0通过检测抗原依赖性反应并在血液系统和实体瘤模型中鉴定情境特异性免疫治疗联合方案,证明了其可行性。它准确预测了初治和复发/难治性弥漫大B细胞淋巴瘤对一线利妥昔单抗的敏感性或耐药性,并揭示了在后续治疗线中具有潜在效用的其他免疫治疗联合方案。
结论:我们开发了一个高内涵功能分析平台,可在生理相关的肿瘤-免疫共培养系统中评估免疫治疗药物组合。经进一步验证,它可帮助临床医生选择有效的免疫治疗。当与分子分析相结合时,Optim.AI™ 2.0或可为由已知或新出现的生物标志物定义的特定患者群体鉴定新型免疫治疗联合方案。

Background: Immunotherapies have advanced cancer treatment, but variable outcomes and the lack of robust predictive biomarkers limit their use. Better patient selection and rational combination strategies could expand their effectiveness. Optim.AI™ is a combinatorial functional precision medicine platform previously shown to identify effective combination treatments for hematologic cancers and sarcoma. Earlier versions guided chemo- and targeted therapy choices but lacked immune components, restricting the drugs assessed. Here, we evaluate the clinical feasibility of Optim.AI™ 2.0, which integrates high-content imaging with tumor-immune ex vivo co-cultures to predict responses to immunotherapy combinations across solid and hematologic tumors.
Methods: For Optim.AI™ 2.0, peripheral blood mononuclear cells and tumor cells (non-Hodgkin lymphomas, gynecological cancers or gastrointestinal cancers) were fluorescently labeled to facilitate cell tracking. Combinatorial drug treatment was carried out on co-culture models with indication-specific 12-drug panels, including monoclonal antibodies, antibody-drug conjugates and bispecific antibodies. High-content imaging analysis of tumor-specific cell death was evaluated for Optim.AI™ 2.0 analysis, which searches 531,441 possible permutations derived from 155 ex vivo test combinations to predictively rank all clinically actionable treatments within the drug panel. Clinically relevant immunotherapies were compared with patient-specific factors-disease stage, subtype, and treatment history-to assess concordance with predicted responses.
Results: Optimized effector-to-target ratios were established to effectively quantify immune-mediated tumor killing, including antibody-dependent cellular cytotoxicity. High-content imaging captured tumor-specific killing and key immune-tumor interactions such as immune cell migration and tumor infiltration. Across multiple indications, Optim.AI™ 2.0 demonstrated feasibility by detecting antigen-dependent responses and identifying context-specific immunotherapy combinations in both hematologic and solid tumor models. It accurately predicted sensitivity or resistance to first-line rituximab in naïve and relapsed/refractory diffuse large B-cell lymphoma and revealed additional immunotherapy combinations with potential utility in later treatment lines.
Conclusion: We developed a high-content functional analytics platform that assesses immunotherapy drug sets in a physiologically relevant tumor-immune co-culture system. With further validation, it could help clinicians select effective immunotherapies. When paired with molecular profiling, Optim.AI™ 2.0 may identify novel immunotherapy combinations for specific patient populations defined by known or emerging biomarkers.
