About Rentschler Biopharma
Rentschler Biopharma is a leading global contract development and manufacturing organization (CDMO) with almost 50 years of proven scientific expertise in biotechnology. From our headquarters in Laupheim, Germany, and our site in Milford, MA, USA, we are your outsourcing partner for bioprocess development and cGMP manufacturing. Our exceptional track record with over 110 different therapeutic protein formats and client-oriented consulting activities, including project management and regulatory support, ensure your project’s success.
We acquired our U.S. site in Milford, MA, in the greater Boston area, in January 2019. The FDA, EMA and Health Canada-licensed, 93,000 square foot facility will be qualified as a multi-product site offering clients innovative solutions. We are expanding the site into a center of excellence, with multiple technologies and capabilities for a variety of products. The first step in the expansion was a 500 L single-use bioreactor, which is already operational. We have broken ground at our new production site, adjacent to our existing site in Milford, MA. The new Rentschler Biopharma Manufacturing Center US (RBMC US) will add 22,000 square feet of manufacturing cleanroom space and house four new 2,000 L single-use bioreactors. With an innovative and highly flexible business model, we are already taking on new projects in Milford, including complex and difficult-to-manufacture proteins.

Rentschler Biopharma offers bioprocess development and cGMP manufacturing for high-quality biopharmaceuticals. Our strength lies in our extensive experience with complex proteins. We provide the best solutions to guarantee the success of your project and meet your clinical and commercial needs.
