美迪西助力
作为纳安生物的临床前研发合作伙伴,美迪西为ADC药物B836提供了药效学研究服务,为RDC药物RB02提供了荷瘤动物模型,以高质量的研究数据赋能临床前研发,并登上国际学术舞台。
“ADC+RDC”诊疗一体化
纳安生物研究重构核药创新逻辑
EANM年会是核医学、分子影像及诊疗一体化领域的国际重要学术会议。此次获选TROP的纳安核药研究将肿瘤靶点表达差异和HER2靶向治疗耐药作为研发出发点,探索双靶点诊疗合一,RDC+ADC协同增效,肿瘤精准治疗的新范式。
围绕肿瘤高表达范靶点HER2和TF(组织因子),纳安基于同一双特异性抗体配体开发出两条管线:放射性药物偶联物RB02和抗体偶联ADC药物B836,研究评估在同一靶点体系下衔接RDC与ADC的开发,及协同增效,克服肿瘤异质性和耐药性的作用机制。
多重临床前数据硬核验证:
强效抗肿瘤、高安全性、精准影像可及
体外实验显示,B836在癌细胞结合与内化效率上显著优于单靶点ADC;体内动物实验中,B836的抗肿瘤疗效超越Enhertu(DS8201);食蟹猴毒理安评研究证实,B836-ADC呈现良好安全治疗窗口。影像学方面,SPECT/CT成像证实核药RB02-177Lu在肿瘤部位快速特异性富集,滞瘤时间7天以上,非靶器官药物在注射后逐步清除。
凭借前沿的差异化创新理念与扎实的研发成果,纳安生物“ADC+RDC”管线组合已获得多项国际顶级学术会议认可:B836已入选AACR专题和ASCO 2026年会,RB02入选ASCO 2026年会,充分印证了纳安生物在双靶点XDC诊疗一体化领域的前瞻性布局与源头创新实力,展现出中国创新药企在全球新药研发赛道的强劲竞争力。

Medicilon Supports Partner Nanolattix, Two RDC and ADC Studies Accepted for EANM’26; HER2/TF Bispecific Research Selected as Top-Rated Oral Presentation
Two studies from Nanolattix Group have been accepted for the 2026 Annual Congress of the European Association of Nuclear Medicine (EANM’26). Among them, “Novel Bispecific RDC+ADC Theranostics Targeting HER2 & TF” has been selected for a Top Rated Oral Presentation (TROP). EANM’26 will take place in Vienna, Austria, from October 17 to 21.
As Nanolattix’s preclinical CRO partner, Medicilon provided pharmacodynamic studies for ADC candidate B836 and tumor-bearing animal models for RDC candidate RB02. High-quality preclinical data generated by Medicilon helped advance the programs.
RDC+ADC Theranostics Strategy: Nanolattix Redefines Radiopharmaceutical Innovation
The EANM Congress is a leading global forum for nuclear medicine, molecular imaging and theranostics. The TROP selected study addresses variable tumor target expression and resistance to HER2-targeted therapies. It explores a new paradigm for precision oncology using bispecific theranostics approach, where RDC and ADC work synergistically.
Leveraging a common bispecific antibody scaffold against the widely expressed tumor antigens HER2 and TF, Nanolattix built two pipelines: radiopharmaceutical conjugate RB02 and antibody-drug conjugate B836. The program evaluates the paired development of RDC and ADC on the same targeting framework, investigating synergistic effects to overcome tumor heterogeneity and drug resistance.
Robust Preclinical Data Demonstrate Potent Anti-Tumor Activity, Favorable Safety and Reliable Imaging Readout
In vitro assays show B836 achieves superior cancer cell binding and internalization compared with monospecific ADCs. In vivo studies demonstrate B836 outperforms Enhertu (DS8201) in anti-tumor efficacy. Cynomolgus monkey toxicology studies confirm a promising therapeutic window for B836. For imaging, SPECT/CT scans confirm rapid, specific tumor uptake of the RB02-177Lu, with tumor retention exceeding seven days and gradual clearance from non-target organs after administration.
Backed by its differentiated innovation and solid preclinical evidence, Nanolattix’s RDC+ADC theranostic strategy has earned recognition at multiple top-tier international conferences. B836 has been featured at AACR and ASCO 2026, while RB02 was accepted for ASCO 2026. These achievements validate Nanolattix’s pioneering strategy in bispecific XDC theranostics.
Medicilon Has Enabled 36 ADCs to Enter Clinical Trials, Continuously Empowering XDC Preclinical R&D
For B836’s preclinical pharmacodynamic assessment, Medicilon deployed its library of over 800 validated tumor efficacy models, including BxPC-3, SK-OV-3, HCT-116, Calu-1, MDA-MB-231, HT-29 and NCI-H446. The panel covers solid tumors such as pancreatic, ovarian, colorectal, lung and triple-negative breast cancers, delivering comprehensive data to support B836’s efficacy profile and broad anti-tumor potential.
Global XDC research is evolving toward refinement, differentiation and combinatorial strategies, shifting from single-target designs to bispecific synergy and theranostics — raising the bar for preclinical characterization. As a leading preclinical CRO for XDCs, Medicilon continues to expand the platform. Medicilon offers one-stop preclinical support spanning payload synthesis, conjugation, pharmacodynamics, pharmacokinetics and safety evaluation. To date, Medicilon has supported 36 ADC programs that have advanced into clinical trials, 5 of which have been out-licensed, with multiple additional XDC projects ongoing.
The EANM’26 acceptance underscores Nanolattix’s innovative strength in RDC+ADC theranostics and brings valuable experience to Medicilon’s XDC preclinical practice. Nanolattix will present its latest findings at the Vienna congress, bringing new insights to global precision oncology. Medicilon will continue to deepen its expertise in XDC preclinical R&D, collaborating with biotech innovators worldwide to tackle drug R&D challenges.
