Leman Biotech Completes New Financing of USD 7 Million to Accelerate Clinical development of “Ultra-Low-Dose” CAR-T


Leman Biotech Co., Ltd. (hereinafter referred to as "Leman Biotech"), a clinical-stage biotechnology company dedicated to the research, development, production, and commercialization of innovative metabolic immunotherapies, is pleased to announce the completion of new financing totaling USD 7 million in Angel+ and Angel++ rounds. New shareholders include Fuho Capital, Yunfan Technology Investment, and private financial investors, while original shareholders Tiantu Capital and XtalPi continue to support Leman Biotech. Additionally, Leman Biotech and its metabolically enhanced CAR-T projects have received various non-dilutive grants amounting to approximately USD 2.7 million. To date, Leman Biotech has secured around USD 20 million in angel financing and project funding. This financing will primarily support the IND application of metabolically enhanced CAR-T cell therapy and the acceleration of clinical research of metabolically enhanced cell therapies for solid tumors.


Co-founded by Professor Li Tang's team from the Swiss Federal Institute of Technology in Lausanne (EPFL) and AI-driven drug R&D company XtalPi in July 2021, Leman Biotech began official operations in February 2022. Meta 10, the core technology of Leman Biotech, has shown great potential to treat solid tumors in preclinical models, with research published in top international academic journals such as Nature Immunology (2021) and Nature Biotechnology (2024). Based on Meta 10, Leman Biotech has established technology platforms with its independent intellectual property rights for the discovery, R&D, and production of biological macromolecule drugs and new immunotherapy cell therapies. The company also utilizes cutting-edge artificial intelligence (AI) technology to iteratively optimize existing drugs, forming three core R&D pipelines: the metabolic reprogramming platform, the metabolically armed cell therapy platform, and the AI-enabled superkine platform.


Leman Biotech’s unique metabolically enhanced CD19 CAR-T cell therapy is currently undergoing investigator initiated trial (IIT) at the First Affiliated Hospital of University of Science and Technology of China (Anhui Provincial Hospital) and the First Affiliated Hospital of Zhejiang University School of Medicine. The project has successfully enrolled and treated more than 20 adult patients with relapsed and refractory leukemia/lymphoma, all of whom have achieved complete remission (CR) and have been discharged. Additionally, the IIT clinical trial of metabolically enhanced CD19 CAR-T was successfully launched at the Children's Hospital of Zhejiang University School of Medicine at the end of March 2024, expanding the therapy's indication to include relapsed or refractory CD19-positive B-cell hematologic malignancies in pediatric patients.


Notably, the metabolically enhanced CD19 CAR-T cell therapy achieved CR in more than 20 patients with an extremely low drug dose—as low as 1% of the commercial CAR-T dose equivalent. This breakthrough could significantly shorten the production cycle of the drug and reduce the production cost of CAR-T, potentially lowering the price of generally expensive cell therapy and increasing the possibility of its inclusion in the Chinese national medical insurance reimbursement list in the future.


Leman Biotech’s IIT clinical data have gained significant attention from peers both domestically and internationally, with the company invited to deliver oral presentations at the Late-Breaking Minisymposium of the American Association for Cancer Research (AACR) 2024, the Late-Breaking Abstracts of the American Society for Gene and Cell Therapy (ASGCT) 2024, the "Gene Therapy, Cellular Immunotherapy, and Vaccination - Biology & Translational Research" session of the European Hematology Association (EHA) 2024, and the annual meeting of the Chinese Society for Cell Biology (CSCB) 2024, among other top academic events. This new round of financing will further advance the clinical development of our metabolically enhanced CAR-T cell therapy.
