Biocytogen Launches “Nano 100 Project” to Develop Fully Human Nanobody Therapeutics for Over 100 Targets
21.2.2023 17:11:00 EET | Business Wire | Press release
Biocytogen Pharmaceuticals (Beijing) Co., Ltd. ("Biocytogen", HKEX: 02315) today announced the launch of the “Nano 100 Project”, which aims to develop fully human nanobody drugs for over 100 targets. The Project combines Biocytogen’s proprietary fully human nanobody mouse, RenNano®, with its high-throughput in vitro and in vivo antibody screening platforms to develop fully human nanobody drugs on a large-scale.
Compared to traditional antibodies, nanobodies have smaller molecular weights and improved tissue penetration ability, which make them effective at infiltrating tumors and crossing blood-brain barriers. Additionally, nanobodies generally have longer CDR3 regions which enables them to recognize hidden epitopes better. Due to their simpler structure, nanobodies are more stable and easier to produce and engineer, making them ideal building blocks for complex modalities such as cell therapy, bispecific antibody and engager, multi-specific antibody, antibody drug-conjugate (ADC), and radionuclide antibody-conjugate (RAC).
After several years of endeavor, Biocytogen successfully engineered the RenNano mouse from its fully human antibody mouse, RenMab™. RenNano mouse possesses full human heavy chain variable regions and can produce heavy-chain-only antibodies (HCAbs). The variable regions of HCAbs, i.e., nanobodies, do not require in vitro humanization to develop drugs. Our research has shown that RenNano mouse can generate robust immune responses after immunizations by different antigens. HCAbs generated from the RenNano mouse have highly diverse CDR3 sequences and can recognize many epitopes with nM-level high affinities. In vitro and in vivo experiments have shown that RenNano-derived antibodies have favorable biological functions.
Based on RenNano’s excellent ability to discover fully human nanobodies, Biocytogen has launched the “Nano 100 Project”. The Project aims to develop fully human therapeutic nanobodies against over 100 targets, including tumor associated antigens (TAAs), GPCRs, immune-checkpoints, cytokines, and factors related to neurological diseases. Biocytogen is actively seeking collaborations with global pharmaceutical and biotech companies to combine its large-scale nanobody development abilities with collaborators’ expertise in nanobody-related therapeutics, such as cell therapies, bispecific and multi-specific antibodies, ADCs and RACs, to develop novel drugs with first-in-class and/or best-in-class potentials.
“We believe that with the ability to rapidly develop fully human nanobodies against selected targets, the ‘Nano 100 Project’ will provide our global partners with more diverse and better nanobody building blocks to accelerate the development of novel drugs,” said Dr. Yuelei Shen, President and CEO of Biocytogen. “Meanwhile, it is also an important supplement to Biocytogen’s Project Integrum.”
About RenNano®
Biocytogen's proprietary fully human nanobody generating mouse, RenNano, is one of the most comprehensive fully human antibody platforms in the world. Nanobody sequences generated from RenNano mice have the highest possible diversity and do not require antibody humanization, which saves time and cost and reduces the risk of failure during later stages of drug development. Additionally, compared to natural HCAb-producing species like camelids, mice are easier to breed and immunize, making them suitable for developing HCAbs on a large scale.
About Biocytogen
Biocytogen (HKEX: 02315) is a global biotechnology company that drives the research and development of novel antibody-based drugs with innovative technologies. Using its proprietary RenMab™/RenLite®/RenNano® mice platforms for fully human monoclonal antibody, bispecific/multispecific antibody and nanobody development, Biocytogen has integrated its in vivo drug efficacy screening platforms and strong clinical development expertise to streamline the entire drug development process. Biocytogen is undertaking a large-scale project to develop first-in-class and/or best-in-class antibody drugs for more than 1000 targets, known as Project Integrum. This project has resulted in 28 drug co-development agreements and 16 RenMice™ licensing agreements with companies around the world, including several partnerships with multinational pharmaceutical companies (MNCs). Biocytogen's pipeline includes 12 core products, among which two products are in phase II multi-regional clinical trials and two products are in phase I. Headquartered in Beijing, Biocytogen has branches in Haimen Jiangsu, Shanghai, Boston, USA and Heidelberg, Germany. For more information, please visit http://en.biocytogen.com.cn.

Agent Assurance by TestMu AI Is Now Generally Available, Letting Teams Test What Their AI Agents Actually Change26.10.2026 17:15:00 EET | Press release
TestMu AI (formerly LambdaTest), the world's first Agentic AI-powered Quality Engineering platform, today announced the general availability of Agent Assurance. Agent Assurance tests AI agents that take actions, such as calling tools, writing files, and changing records, by checking what a run actually changed rather than what the agent says it did. Any team can now create a TestMu AI account and run it against its own agent without booking a demo first. Agent Assurance launched on August 17, 2026, behind a waitlist and a guided onboarding session. Since then, Rook, the CLI that runs Agent Assurance, has shipped a steady run of releases, shaped by feedback from early teams. Agent evaluation has mostly graded the final reply, and that reply can be wrong about the agent's own work. In CXBench, a benchmark of LLM agents in regulated customer-experience workflows published in October 2026, 80.1% of runs that reached the right outcome still failed the process checks, and only 13.8% passed b
