About PeptiStar
PeptiStar Inc. is a contract development and manufacturing organization (CDMO) specializing in peptide and oligonucleotide Active Pharmaceutical Ingredients (APIs). Founded on September 1, 2017, the company was established as a joint venture by PeptiDream Inc., Shionogi & Co., Ltd., and Sekisui Chemical Co., Ltd. Located in Settsu, Osaka, Japan, PeptiStar's President and CEO is Shinichiro Fujiie. Mr. Fujiie, a graduate of Kyushu University, began his career at Shionogi & Co., Ltd. in 2000, where he gained experience in pharmaceutical ingredient manufacturing, cost reduction through international suppliers, and new product launches before joining PeptiStar.
The company's business model centers on providing comprehensive, value-added contract services for the pharmaceutical industry, from research and development through to clinical trials and commercial production. PeptiStar addresses the manufacturing challenges of middle-molecule drugs, such as peptides and nucleic acids, which are often a bottleneck in the development of new treatments. By consolidating advanced technologies from various Japanese companies, PeptiStar aims to improve the efficiency of the drug development supply chain. The firm serves pharmaceutical companies, startups, and academic institutions both domestically and internationally.
PeptiStar offers development and manufacturing for a wide range of products, including complex and special peptide APIs like long-chain and cyclic peptides, as well as oligonucleotide APIs. A key feature of its service is its state-of-the-art facilities, which include some of the largest filter reactors and lyophilizers in Japan, allowing for production from milligram research scale up to several hundred kilograms for commercial supply. The company utilizes innovative manufacturing technologies such as the Microwave Solid-Phase Peptide Synthesis (SPPS) method, Continuous Chromatography Purification, and a specialized lyophilization process to enhance quality, reduce costs, and shorten delivery times.
