中国上海·浙江绍兴 2026年9月23日——三优生物医药(上海)有限公司(以下简称“三优生物”)与浙江新码生物医药股份有限公司(以下简称“新码生物”)共同宣布,双方正式签署战略合作协议。此次合作将聚焦创新ADC药物的联合开发,充分发挥三优生物在智能超万亿分子库(AI-STAL)及智能新药加速器(SAI-DA)驱动的创新ADC发现领域的优势,以及新码生物在非天然氨基酸定点偶联技术领域的深厚积淀,为全球肿瘤患者开发更具临床价值的创新疗法。
三优生物与新码生物签署战略合作协议
ADC 药物的核心竞争力,始于抗体的靶向精准性,成于偶联工艺的稳定可控。新码生物自主开发的非天然氨基酸定点偶联技术平台 NovoCode ™,通过在抗体上精确插入非天然氨基酸,实现了偶联位点的定点可控,保障 ADC 药物具备高度均一性,区别于传统随机偶联得到的混合物。这一技术路径已在 ARX788 的Ⅲ期关键临床研究中得到验证,并助力 ARX305 在 CD70 高表达晚期肾癌的治疗中展现出高安全窗与持久抗肿瘤活性。
三优生物创新 ADC 发现平台建立于 2020 年,在项目设计和工艺开发方面拥有丰富的经验,已成功交付了 800 多个 ADC 偶联项目。尤其在新型 ADC 分子形式方面,三优生物建立起双靶 ADC 与双载荷 ADC 的分子发现与设计能力:双靶 ADC 通过靶向两个不同抗原表位提升肿瘤选择性,双载荷 ADC 则通过搭载两种不同作用机制的载荷拓展治疗窗口、克服耐药。这两类创新分子形式恰好可以通过新码生物的 NovoCode ™平台充分释放其设计潜力。双方在这一方向的协同探索,有望为下一代 ADC 药物开发打开新的技术空间。
本次战略合作将围绕以下重点方向展开:
◆ 抗体发现与定点偶联对接: 三优生物利用 AI-STAL 平台筛选高内吞效率、高靶点特异性的抗体候选分子,新码生物基于 NovoCode ™平台完成定点偶联工艺开发,从源头建立“抗体特性—偶联策略”协同评估。
◆ 双靶 ADC 与双载荷 ADC 联合探索: 结合三优生物的分子设计能力与新码生物的定点偶联平台,推进双靶 ADC 靶点组合评估、双载荷 ADC 载荷配对筛选及临床前概念验证。
◆ 研发闭环构建: 双方建立联合项目团队,打通从靶点调研、抗体筛选到偶联工艺、体内外评价的全流程,加速候选 ADC 分子开发。
新码生物董事长兼CEO梁学军表示: “ADC药物的成败,很大程度上取决于抗体分子与偶联策略之间的‘匹配度’。新码生物的非天然氨基酸定点偶联技术平台NovoCode™,核心优势在于可实现偶联位点的精确控制与药物分子的高度均一性。三优生物的AI-STAL和SAI-DA平台在海量分子库中快速锁定优质候选抗体的能力,为我们从‘工艺端’向‘分子端’前移提供了关键支撑,同时三优生物拥有的双靶ADC和双载荷ADC偶联技术,也是目前创新ADC的主流方向。我们期待通过此次合作,共同开发出安全窗更宽、疗效更持久的创新ADC药物。”
三优生物创始人兼CEO郎国竣表示: “新码生物的非天然氨基酸定点偶联技术路线在临床中已得到充分验证。此次合作的价值在于,三优生物将分子发现能力与创新ADC研发能力直接服务于一个已完成临床验证的ADC技术平台,这意味着我们能够在一个确定性更高的偶联体系中快速实现双载荷ADC的构建价值转化。这是一种‘源头创新’与‘工艺验证’之间的高效耦合,我们对此充满期待。”
此次合作是三优生物在ADC赛道深化产业协同的重要布局。双方将充分发挥各自在创新ADC领域的专长,致力于推动下一代ADC药物的高效开发,为创新性ADC药物的研发构建源头创新优势。

Strategic Collaboration | Sanyou Bio and NovoCodex Partner to Co-Develop Innovative Dual-Payload ADCs
Shanghai, China · Shaoxing, Zhejiang, China — September 23, 2026 — Sanyou Biopharmaceuticals Co., Ltd. (“Sanyou Bio”) and NovoCodex Biopharmaceuticals Co., Ltd. (“NovoCodex”) jointly announced today that the two companies have formally entered into a strategic collaboration agreement. The partnership will focus on the joint development of innovative antibody-drug conjugates (ADCs), leveraging Sanyou Bio’s strengths in innovative ADC discovery powered by its AI-Super trillion antibody/molecule libraries (AI-STAL) and Sanyou AI-Drug Accelerator (SAI-DA), together with NovoCodex’s extensive expertise in site-specific conjugation technology using unnatural amino acids. Through this collaboration, the two companies will jointly advance the development of innovative ADC therapeutics and work to deliver therapies with greater clinical value to cancer patients worldwide.
Sanyou Bio and NovoCodex sign a strategic collaboration agreement
The core competitiveness of ADC therapeutics begins with the precision of antibody targeting and is realized through stable and controllable conjugation processes. NovoCodex’s proprietary site-specific conjugation technology platform, NovoCode™, precisely incorporates unnatural amino acids into antibodies to achieve defined and controllable conjugation sites, ensuring a highly homogeneous ADC product rather than the heterogeneous mixtures generated by traditional random conjugation approaches. This technology has been validated in the pivotal Phase III clinical trial of ARX788, and has supported ARX305 in demonstrating a favorable safety window and durable antitumor activity in patients with advanced renal cancer with high CD70 expression.
Sanyou Bio’s innovative ADC discovery platform was established in 2020 and has extensive experience in project design and process development, having successfully delivered more than 800 ADC conjugation projects. Particularly in the development of novel ADC molecular formats, Sanyou Bio has established capabilities in the discovery and design of dual-target ADCs and dual-payload ADCs. Dual-target ADCs enhance tumor selectivity by targeting two distinct antigen epitopes, while dual-payload ADCs expand the therapeutic window and help overcome drug resistance by incorporating two payloads with different mechanisms of action. These two innovative molecular formats are particularly well suited to have their design potential fully unlocked through NovoCodex’s NovoCode™ platform.
The two companies’ synergistic exploration in this area is expected to open up new technological possibilities for the development of next-generation ADC therapeutics.
The strategic collaboration will focus on the following key areas:
◆ Integration of Antibody Discovery and Site-Specific Conjugation:
Sanyou Bio will leverage the AI-STAL platform to screen antibody candidates with high internalization efficiency and high target specificity, while NovoCodex will use the NovoCode™ platform to develop site-specific conjugation processes, establishing a coordinated evaluation of antibody characteristics and conjugation strategies from the outset.
◆ Joint Exploration of Dual-Target and Dual-Payload ADCs:
Combining Sanyou Bio’s molecular design capabilities with NovoCodex’s site-specific conjugation platform, the two companies will advance the evaluation of target combinations for dual-target ADCs, the screening of payload pairs for dual-payload ADCs, and preclinical proof-of-concept studies.
◆ Building a Closed-Loop R&D Workflow:
The two companies will establish joint project teams to integrate the entire development process, from target research and antibody screening through conjugation process development and in vitro and in vivo evaluation, thereby accelerating the development of ADC candidates.
Dr. Xuejun Liang, Chairman and CEO of NovoCodex, said:
“The success of an ADC therapeutic depends, to a significant extent, on the degree of compatibility between the antibody molecule and the conjugation strategy. Sanyou Bio’s AI-STAL and SAI-DA platforms can rapidly identify high-quality antibody candidates from massive molecular libraries, providing critical support for us to move upstream from process development toward the molecular design stage. At the same time, Sanyou Bio’s capabilities in dual-target ADCs and dual-payload ADCs represent major directions in the development of innovative ADCs today. Through this collaboration, we look forward to jointly developing innovative ADC therapeutics with a wider safety window and more durable efficacy.”
Dr. Guojun Lang, Founder and CEO of Sanyou Bio, said:
“NovoCodex’s site-specific conjugation technology based on unnatural amino acids has been extensively validated in clinical development. NovoCodex’s unnatural amino acid-based site-specific conjugation platform, NovoCode™, offers the key advantages of precise control over conjugation sites and a high degree of molecular homogeneity. The value of this collaboration lies in enabling Sanyou Bio’s molecular discovery capabilities and innovative ADC R&D capabilities to directly serve an ADC technology platform already validated in clinical development. This means that we can rapidly translate the value of dual-payload ADC engineering into therapeutic candidates within a more predictable conjugation system. It represents an efficient integration of ‘innovation at the source’ and ‘process validation,’ and we look forward to the opportunities this collaboration will bring.”
This strategic partnership marks a key milestone for Sanyou as it deepens industry-wide collaboration across the ADC landscape. Drawing on each party’s complementary strengths in novel ADC development, Sanyou Bio and NovoCodex aim to streamline development of next-generation ADCs and build source-level innovation advantages for ADC drug discovery.
