Established in 2014, we have focused on the integration of multiple interdisciplinary technologies and established our own microfluidic technology platform. Utilizing the physical and molecular biological characteristics of tumor cells, we have developed various advanced and original research through the joint application of semiconductor technology and biotechnology. This includes complex precision structures, dielectric detection, functional microfluidic biochips, microfluidic integrated semiconductor sensors, related application modules, and key components of medical testing equipment. We have also developed a series of medical testing equipment and related products by integrating various functions of microfluidic modules, automation software, and hardware. Our technologies and products can be used for early screening and detection, diagnosis and staging, and treatment of cancer through the detection of circulating tumor cells and related tumor markers in blood samples, capture of single circulating tumor cells, and single-cell sorting and determination. These products provide assistance in treatment selection and patient prognosis intervention once the required licenses and approvals have been obtained.

We are committed to the application research of integrating semiconductor technology and biotechnology. Through the enrichment, capture, and identification of circulating tumor cells and related tumor marker cells in the field of liquid biopsy, we aim to provide cancer patients with rapid and affordable assay products and services. These services include early screening and detection, diagnosis and staging, treatment selection, and patient outcome interventions for cancer.

We operate through Advanced Biomed Inc. (Taiwan) (“Advanced Biomed Taiwan”) and Advanced Biomed HK Limited (“Advanced Biomed HK”). Advanced Biomed Taiwan is responsible for the main operation and the design and development of the company's primary technologies and products. Advanced Biotech HK is our first localized operation company, mainly responsible for market operation and management in China, localized production, product registration, and future local market sales of our products in accordance with relevant local regulations in China. Our Shanghai subsidiary owns some of our R&D equipment and patents and will be responsible for operations related to clinical trials in Mainland China through CROs. In the future, we also plan to establish operation centers in countries and regions in North America and Europe.

Devices and Products

Our devices, A+Pre, AC-1000, A+CellScan, and A+SCDrop, and three corresponding microfluidic biochips, A+Pre Chip and AC-1000 CTC Enrichment Chip and A+CellScan Chip, are designed to provide rapid and affordable assay products and services to cancer patients. Among them, A+Pre is mainly used to reduce the viscosity of blood samples, and AC-1000 is used to complete the separation and enrichment of circulating tumor cells (“CTCs”) and tumor-related targeted cells in blood samples. The A+CellScan is mainly used for fluorescent labeling and automatic scanning judgment of targeted cells while A+SCDrop preserves the original viability of single cells.

Additionally, we have finished the research and development stage for four matching immunostaining kits, A+CTCE, A+CTCM, A+EMT and A+CM, and submitted registration applications in China. The immunostaining kit use antibodies combined with fluorescent groups of different colors to bind to specific proteins on the cell surface or inside the cells. The presence and intensity of fluorescent signals can be observed through a separate fluorescent imaging system, and the expression of the target protein and the cell type can be judged and determined accordingly. Different cell types can be distinguished using multiplexed combined staining with different antibodies. The A+CTCE kit is mainly used to identify epithelial circulating tumor cells, the A+CTCM kit is used to identify mesenchymal circulating tumor cells, the A+EMT kit is mainly used to identify epithelial-to-mesenchymal circulating tumor cells, and the A+CM kit is used to identify tumor-associated macrophages (cancer-associated macrophage-like cells).

We also developed a product for early screening of lung cancer, the A+LCGuard Lung Cancer Early Screening Kit (“A+LCGuard”), which is used to assist in the determination of benign and malignant pulmonary nodules. From August 2020 to September 2022, we finalized the research, design, and development of A+LCGuard. We plan to start A+LCGuard’s clinical research by the end of June 2025. By the end of September 2025, we expect that the clinical research protocol may pass ethical review and receive ethics committee approval. Thereafter, we plan to initiate the trial stage of the clinical research, with completion anticipated within six months of October 2025. 

R&D Progress

All of our products must go through three steps to receive the required clearance from the (National Medical Products Administration of China (“NMPA”) before they can be sold to customers. The three steps are research and development, registration application, and registration review, which must be done in that order. Currently, A+Pre and AC-1000 and their corresponding chips have been cleared by the NMPA; the four matching immunostaining kits and A+SCDrop are under registration review; A+CellScan, A+CellScan Chip, and A+LCGuard are ready to start their registration applications. As of the date of this prospectus, we have not applied for similar clearances from other jurisdictions.

We participated in a scientific research project at Shanghai Pulmonary Hospital from July 17, 2019 to December 2021, and completed a total of 123 case studies to test A+Pre, AC-1000 and A+LCGuard. In the study, we selected 123 individuals, and among them, 75 were surgical patients with nodular changes or shadows in the lungs reported by imaging studies and 48 healthy patients without lung nodules reported by imaging studies. 7ml blood samples were taken from test subjects either before the clinical operation (for cancer patients) or after the physical examination (for healthy individuals), and A+Pre, AC-1000, and A+LCGuard kits were used to determine whether there were circulating tumor cells and other tumor markers in the blood samples. Finally, the pathological and physical examination results of the tested individuals were compared with the test results of our products. Our test results achieved 96% sensitivity and 99.9% specificity, which provides the research and development basis for our products. Specifically, A+Pre and AC-1000 were at the research and development stage, and we completed their effectiveness and performance indicators testing through this project. At the same time, A+LCGuard finished its feasibility and functional verification testing. All three products were tested together throughout the entire project.
