PeptiStar Inc. was founded with the mission to garner top level technologies developed in Japan to manufacture various peptides efficiently and with high quality in a state-of-the-art facility. We are an R&D focused CDMO (Contract Development and Manufacturing Organization) that proactively face difficult challenges through continuous efforts in innovating our technology. PeptiStar is focused not only in organic chemistry or optimizing synthesis technology from process chemistry perspective, but in physical chemistry and chemical engineering technologies, and our pursuit of innovation spans all processes including purification, solidification, and drying and not only in the synthesis process. We will continue our technology innovation, hoping to help patients by delivering pharmaceuticals that were difficult to introduce to the market in the past due to reasons like “efficacy is good, but manufacturing is difficult and/or too costly.” Our company has a coherent production system to handle production from non-GMP samples all the way up to cGMP commercial production and therefore, it is possible to manufacture high quality products by solving challenges that come up during the scale-up stage. We continue to hone our skills as a peptide CDMO that our clients can rely from the development phase. We look forward to serving to your needs.

I have been involved with the company since its launch with an aspiration to create “a new structure that surpasses the traditional boundaries of an enterprise in order to revitalize the Japanese healthcare industry.” Now that we are at the start point, I am realizing again that PeptiStar is a company filled with peoples’ hopes and expectations.
Although CDMO is not in the limelight of healthcare industry, it is a critical component of the value chain indispensable for delivering solutions to a wide patient base. We strive to break out of mold of traditional practices in order to grow the peptide API manufacturing as a technology that Japan can be proud of. We look forward to serving your needs.

The founding members of PeptiStar converged in Osaka with a strong passion to “deliver innovative peptide pharmaceuticals to the world from Japan.” Thanks to all the support we received, we were able to conduct the completion ceremony of our HQ, research lab and factory on July 11 of this year and started a full-fledged operation. By listening and responding carefully to clients’ needs with the end result of improving the QOL of their global patient base, we will pursue the innovation around peptide pharmaceutical manufacturing by realizing timely and stable supply of high-quality products with cost competitiveness. As a CDMO that pulled together the essence of Japanese technology, we will continue the challenge of delivering high quality API. We look forward to serving your needs.
