Orizuru Therapeutics

Orizuru Therapeutics operates as a research and development-focused company advancing induced pluripotent stem cell (iPSC) technology into clinical applications. Established in April 2021, the firm is a spinout from a joint research program between Takeda Pharmaceutical Company and Kyoto University's Center for iPS Cell Research and Application (CiRA), known as T-CiRA. This program, initiated in 2015 and led by Professor Shinya Yamanaka, aimed to accelerate the practical application of iPSC technology. Orizuru Therapeutics was founded by Kenji Nonaka, who serves as President and CEO, to inherit and commercialize promising research assets from T-CiRA.

The company's business model is twofold. The primary focus is developing regenerative medicine products through cell transplantation. Its two lead programs are OZTx-556, iPSC-derived cardiomyocytes for severe chronic heart failure, and OZTx-410, iPSC-derived pancreatic islet cells for brittle type 1 diabetes. The second part of its business involves providing services and expertise related to iPSC technology to support drug discovery research for other pharmaceutical companies and academic institutions. This includes contract research, consulting, and on-site technical support. The company generates revenue through these support services and aims for future commercialization of its therapeutic products, with a target to obtain initial clinical data and pursue an IPO by 2026.

Orizuru's core technology centers on proprietary methods for differentiating, purifying, and culturing iPSCs at a large scale. For its cardiomyocyte product, OZTx-556, the company uses small-molecule compounds to achieve high purity (around 98%) and a mass production-friendly suspension culture system, which is crucial for delivering the large cell quantities required for heart therapies. This product is designed to be a cryopreservable, off-the-shelf cell therapy. Similarly, the pancreatic islet cell product, OZTx-410, utilizes unique compound-based purification methods to ensure a high purity of endocrine cells, which have shown efficacy in animal models. The company has secured significant funding, raising over JPY 10 billion through multiple rounds, including a Series B in February 2024, from investors like Kyoto University Innovation Capital, Takeda, and various venture capital firms.
