Advance your peptide characterization and formulation development
Peptide therapeutics are very attractive active pharmaceutical ingredients nowadays due to their good specificity and a more affordable production compared to protein therapeutics. Eurofins CDMO is aware of the benefits as well as the challenges associated with peptide drug substances and related drug products. Next to a broad set of characterization techniques, formulation development is crucial to develop your peptide therapeutic into a stable drug product.

Get to know your peptide
Growing understanding of your therapeutic peptide and its behavior can overcome analytical and formulation challenges, allowing faster progress through clinical trials and successful delivery to patients. Peptides are prone to degradation, oxidation and other modifications posing additional analytical challenges which require sensitive and robust analytical methods for detection and quantification of peptide-related impurities. Efficient, selective, and reliable separation-driven analysis techniques are required for:
- Peptides synthesized with natural or chemically altered amino acids
- Modified peptides to improve biological activity, selectivity, stability and solubility
- Complex peptide mixtures with diverse physicochemical properties
Specialized expertise and state-of-the-art analytical capabilities ensuring high quality results within an acceptable timeline:

Our integrated analytical support
Our analytical services include method development, and subsequent method qualification and validation to ICH guidelines, drug product release testing and stability studies:
- Forced degradation studies (e.g., humidity, temperature, pH, oxidation)
- Photostability studies
- In-use stability studies
- ICH stability studies and testing
- Accelerated Stability Assessment Program (ASAP) studies for drug product prototype ranking and shelf-life predictions
Liquid Drug products
Peptide drugs are often formulated in liquid dosage forms for parenteral administration. Solubility of the peptide at the right dose as well as compatibility with the used excipients are key aspects. These aspects will be screened at the start of the project and form the fundamental base for further formulation development. Knowing the cost of the peptide drug substance as well as the limited availability in early stages of the project, we strive to miniaturize the drug substance consumption in each step of the formulation development process. Are you looking into formulating a cocktail of peptides? Eurofins CDMO has expertise to get your peptide mixtures in its final drug product. We can work on any of the following drug products:
- Solution in vials or prefilled syringes for parenteral injection
- Ophthalmic drug products like eye drop or eye injections
- Nasal spray
- Solution for inhalation
Clinical manufacturing of your developed formulation is the next step in which Eurofins CDMO can support you. Our expertise in upscaling and transfer to a GMP environment is a plus for your project. Eurofins CDMO is capable of producing both sterile and non-sterile drug products with all required analytics in-house.


Increasing stability
Stability testing of your peptide drug product is a crucial step within the formulation development process. In case the stability of the peptide is challenging, other services of our CDMO can come into scope. Whether it is an optimization of the formulation like adding an antioxidant, or there is need to change the dosage form, we are ready to take the lead. A freeze-dried drug product might be the solution to increase the stability of your peptide drug product.
To develop a freeze-dried drug product, your project can go through the following steps:
- Buffer and excipient screening
- Lyophilization screening of different concepts often supported by design of experiments
- Extensive analytical support including water content analysis
- Short stress studies and accelerated stress studies
- Freeze drying cycle optimization
- Transfer to GMP scale freeze-dryer
- Clinical production
