FRONTEO and TAGCyx Bio concluded a PoC (Proof of Concept) feasibility agreement to explore new therapeutic targets and indications for artificial nucleic acid aptamers utilizing Drug Discovery AI Factory
FRONTEO, Inc. (Headquarter: Minato-ku, Tokyo, President & CEO: Masahiro Morimoto, hereinafter referred to as “FRONTEO”) and TAGCyx Biotechnologies Inc. (Headquarter: Meguro-ku, Tokyo, President & CEO: Chizuko Koseki, hereinafter referred to as “TAGCyx Bio”), a start-up biotech company developing innovative pharmaceuticals and diagnostic technologies using artificial nucleic acid aptamers*1 based on artificial base technology*2, are pleased to announce that we concluded a PoC (Proof of Concept) feasibility agreement to explore new therapeutic targets and indications for artificial nucleic acid aptamers developed by TAGCyx Bio using Drug Discovery AI Factory (DDAIF)*3 provided by FRONTEO.
This is a new approach aimed at accelerating the search for new target molecules and indications by utilizing AI in drug discovery research for artificial nucleic acid aptamers. Through the literature information analysis of “DDAIF”, to discover the potential relationship between diseases and target molecules that were difficult to find using conventional methods, it is expected that the possibility of drug discovery for artificial nucleic acid aptamers will be dramatically expanded.
■Features of both companies
FRONTEO has a proprietary technology to discontinuously discover “unknown relationships between diseases and target molecules” which associations are not documented in literatures by utilizing in-house developed AI “KIBIT”. “DDAIF” based on this technology has strengths in extracting highly novel target molecule candidates and analyzing disease mechanisms, and has being increasing adopted, primarily by major pharmaceutical companies.
On the other hand, TAGCyx Bio has a drug discovery platform based on artificial nucleic acid containing aptamers utilizing its proprietary technology, and is promoting research and development of oligonucleotide*4 therapeutics for autoimmune diseases, women’s diseases, kidney diseases and others. The efforts to commercialize the aptamers are accelerating both domestically and internationally, joint research with the University of Tokyo and Toray Industries Corporation on the treatment of pre-eclampsia during pregnancy*5, and the phase 2 clinical trial on vitiligo treatment has been started*6 by CAGE Bio Inc. (United States) based on the technology license.
■Overview of this PoC
In this PoC, new target molecule candidates and potential disease areas for artificial nucleic acid aptamers, and the possibility of adaptive expansion of existing nucleic acid aptamers will be explored systematically by utilizing FRONTEO’s “DDAIF”. By integrating the technologies and knowledge of both companies, we aim to expand options for creating new oligonucleotide therapeutics and contribute to solving unmet medical needs*7.
■Comment from TAGCyx Bio CEO Chizuko Koseki
“TAGCyx Bio is developing DNA aptamer drugs using artificial base technology, focusing on unmet needs in disease areas that cannot be targeted by antibody drugs due to the difficulty of formulation. While manually searching for and exploring targets by TAGCyx team that cannot be targeted by conventional modalities, we found out the potential of the AI search of FRONTEO’s “DDAIF” can be applied. We are excited about the possibility of gaining insights that exceed the manual search capabilities.”
■Comment from FRONTEO Director/CSO (Chief Science Officer) Hiroyoshi Toyoshiba
“FRONTEO’s strength is to discontinuously discover the unknown relationship between diseases and target molecules and disease mechanism which are not documented in literature in the world by utilizing proprietary AI and analysis technology. In this time, through integrating our “DDAIF” and TAGCyx Bio’s innovative novel artificial base pair technology, we expect that the potential applications of artificial nucleic acid aptamers to new diseases will be greatly expanded. We hope that this PoC will contribute to the creation of innovative oligonucleotide therapeutics, the resolution of unmet medical needs, and the development of Japanese pharmaceutical industry.”
*1 Nucleic acid aptamers: Short, single-stranded DNA or RNA molecules that bind to specific target molecules with high specificity. Due to its strong binding to target molecules and high safety and stability, it is expected to have extensive applications in diagnostic and therapeutic applications.
*2 Artificial base technology: A technology that develops new chemically synthesized bases (artificial bases) that are different from the four types of DNA bases (A, T, G and C) that exist in nature and incorporates them into DNA.
*3 DDAIF: An AI drug discovery support service in which FRONTEO’s drug discovery experts, who are well-versed in AI and drug discovery, use KIBIT’s natural language processing technology and proprietary analysis methods to search for target molecules and indications and provide supporting hypotheses.
*4 Oligonucleotide: Polymers that retain and transmit genetic information of living organisms, such as DNA and RNA.

*6 News release dated October 24, 2025, “CAGE Bio Announces Initiation of a Phase 2 Clinical Trial of CGB-600, a novel topical DNA aptamer therapy for the treatment of vitiligo” https://tagcyx.com/archives/1197
*7 Unmet medical needs: Needs for new drugs and therapies for diseases for which no effective treatment has been found
■About TAGCyx Biotechnologies Inc. URL: https://tagcyx.com/
A start-up venture company from the University of Tokyo, which has the world’s leading technology platform of new artificial base pair, and is creating proprietary novel nucleic acid aptamers and promoting development in the fields of drug discovery and medical devices. The nucleic acid aptamer molecules with high specificity and stability can be created. The most advanced project has started clinical trials as a dermal application candidate for the treatment of vitiligo, an autoimmune disease of the skin, by the licensee company in the US. We aim to develop drugs for local administration and those focused on women-oriented diseases by taking advantages that our aptamer can be applied the formulation methods which are considered very difficult to develop for antibody drugs, and the fact that the molecules are difficult to penetrate the placenta.
