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 100 different therapeutic protein formats and client-oriented consulting activities, including project management and regulatory support, ensure your project’s success.

With Rentschler Biopharma, you are in expert hands.

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 are also hiring additional people at the site to keep pace with the facility’s growth in both size and new business. With an innovative and highly flexible business model, we are already taking on new projects in Milford, including complex and difficult-to-manufacture proteins.

Why partner with Rentschler Biopharma?

Fusion proteins, recombinant enzymes, monoclonal and multi-specific antibodies are among the 100 different formats that we have handled. Our track record of 300 molecules for 150 clients worldwide translates into unrivalled experience along the entire biopharmaceutical value chain. We guarantee best-fit solutions for your product by balancing timeline requirements with a comprehensive manufacturability assessment, always putting quality first.
