Pfanstiehl is a leading current good manufacturing practice (cGMP) manufacturer of parenteral grade excipients and highly potent active pharmaceutical ingredients (API).
Pfanstiehl develops and manufactures high-purity, low-endotoxin (HPLE) carbohydrates such as trehalose, sucrose, mannitol, galactose, maltose and mannose utilized as injectable excipients for the stabilization of proteins, mAbs and vaccines. These HPLEs are also used as supplements for industrial cell culture, cell therapy and cryopreservation media.
Pfanstiehl works closely with many of the world's largest multinational pharmaceutical and biopharmaceutical firms, as well as virtual pharmaceutical companies, to synthesize proprietary and commercial compounds in quantities ranging from grams to tonnes.
Pfanstiehl has a 40-year history in custom synthesis, custom manufacturing and process scale-up development. The company is based near Chicago, Illinois, US.
Customized manufacturing services
Whether you are working at an innovator company on a novel formulation or at a biosimilar firm trying to replicate an existing tried and true formulation, consider Pfanstiehl as your pure source for a plug and play solution.
Pfanstiehl can provide custom synthesis of new chemical entities (NCE), specialty carbohydrates and injectable-quality, cGMP pharmaceutical ingredients in commercial quantities. Our capabilities include process scale-up, development and process validation, according to cGMP guidelines. Our facilities and equipment are configured to produce HPLE compounds, including potent (highly active toxic or cytotoxic) drugs under cGMP conditions.
As a long-time manufacturer of low-endotoxin carbohydrates, injectable grade excipients, active pharmaceutical ingredients (API) and pharmaceutical intermediates, Pfanstiehl can establish and maintain US and European drug master files (DMF) and European 'Certificates of Suitability' for your product. Pfanstiehl is here to help you get your compound to market, seamlessly bridging the critical gap between product development and regulatory approval.
To suit your needs we perform a wide range of chemistries and purification techniques, including but not limited to:

Narrowing the Gap Between Active Ingredients and Critical Excipients The increasing complexity of large molecule and cell-based therapeutics calls for an evolution in our understanding of the impurity and functional contributions of each formulation component.
Closing Characterisation Gap Between API and Formulation Components This whitepaper will provide an introduction to high-purity carbohydrates often used for applications such as stabilisation, modulation, and cryopreservation, comparing the old paradigm that formulation components are inactive ingredients with limited functionality with the new paradigm, which suggests these components play a significant role in therapeutic stability, quality, potency, immunogenicity, and bioavailability.
Validated Metal Analysis of Injectable Grade Platform Excipients Four commonly utilized carbohydrates for ptotein stabilization are Sucrose, Trehalose, Mannitol, and Maltose.
Trehalose: A Powerful Excipient in the Formulation Toolbox In the pharmaceutical industry, products that benefit from the stabilising effects of trehalose include, but are not limited to, monoclonal antibodies (mAbs), antibody drug conjugates (ADCs), fusion proteins, peptides, stem cells and vaccines.
