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.

Incyte Announces Positive CHMP Opinion for Opzelura ® (ruxolitinib) Cream for the Treatment of Adults with Moderate Atopic Dermatitis26.6.2026 14:30:00 EEST | Press release

Incyte (Nasdaq: INCY) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has issued a positive opinion recommending the approval of Opzelura® (ruxolitinib) cream for the treatment of moderate atopic dermatitis (AD) in adult patients for whom topical corticosteroids (TCSs) and topical calcineurin inhibitors (TCIs) are inadequate or inappropriate. “AD is a chronic skin condition that can have a significant impact on daily life. The positive CHMP opinion for Opzelura marks meaningful progress toward bringing the first non-steroidal topical JAK treatment option to adults in Europe with moderate AD for whom standard topical therapies have failed,” said Lee Heeson, Executive Vice President and Head of Incyte International. “If approved by the European Commission, Opzelura could help address an important gap for patients who have limited treatment options when TCSs and TCIs are inadequate or inappropriate.” The positive CHMP o

Datroway ® Recommended for Approval in the EU by CHMP as First-Line Treatment for Patients with Metastatic Triple Negative Breast Cancer Who Are Not Candidates for Immunotherapy26.6.2026 14:00:00 EEST | Press release

Datroway® (datopotamab deruxtecan) has been recommended for approval in the European Union (EU) as monotherapy for the first-line treatment of adult patients with unresectable or metastatic triple negative breast cancer (TNBC) who are not candidates for PD-1/PD-L1 inhibitor therapy. Datroway is a specifically engineered TROP2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/NYSE: AZN). The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based its positive opinion on results from the TROPION-Breast02phase 3 trial, which werepresented at the 2025 European Society for Medical Oncology Congress and published in Annals of Oncology. The recommendation will now be reviewed by the European Commission, which has the authority to grant marketing authorizations for medicines in the EU. In TROPION-Breast02, Datroway demonstrated a

DAYBU ® (trofinetide) Recommended for Approval in the European Union by CHMP26.6.2026 13:49:00 EEST | Press release

Acadia Pharmaceuticals Inc. (Nasdaq: ACAD) today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion following a re-examination procedure, recommending the granting of a marketing authorization for DAYBU® (trofinetide) for the treatment of neurobehavioral symptoms of Rett syndrome in adults and pediatric patients aged five years and older. If granted marketing authorization by the European Commission, DAYBU® would be the first therapy approved for this indication in the European Union (EU). “The CHMP’s positive opinion for DAYBU® is an important milestone in our mission to bring this innovative therapy to the EU, where there are no therapies specifically approved for the neurobehavioral symptoms of this devastating condition," said Catherine Owen Adams, Acadia’s Chief Executive Officer. “Our commitment is to make a meaningful difference in the lives of patients, caregivers, and the wider Rett com
