High Protein Concentration Formulations

A science-based approach to develop best-in-class formulations for convenient use in pre-filled syringes and cartridges.

ProJect Pharmaceutics has specialized in this emerging field with a key expertise in development of stable, effective and syringe-able formulations together with their eligible processes.

Transforming therapeutic proteins into high-concentrated, stable and easy to use medications for subcutaneous self-injection can add up to a major challenge along their clinical development. A formulation’s fundamental qualification, such as appropriate physico-chemical stability, container material compatibility and viscosity must be taken into account to support an acceptable in-syringe shelf-life, as well as convenience in regard to syringe-ability. In order to address these various requirements and develop a pioneering new drug in a pre-filled syringe presentation, a great extent of knowledge, expertise and sophisticated analytics is needed that are sparingly found in this developing market to date.

ProJect Pharmaceutics has specialized in this emerging field with a key expertise in development of stable, effective and syringe-able formulations together with their eligible processes. Be it conformation of de-novo drug products towards a pre-filled syringe application or transfer of existing drug products into the like, ProJect Pharmaceutics features all the required key qualifications.

By applying an elaborate science-based approach to meet well-established critical quality attributes such as e.g. maximum effectiveness, high concentration for low injection volume, low aggregate content and low viscosity, ProJect Pharmaceutics offers profound guidance and support on the development of pioneering parenteral biologics.

Minimizing viscosity and aggregation by actively maximizing repulsive protein-protein interaction in solution is one of the key techniques applied. Additionally, shifting thermodynamic protein stability in solution to its maximum represents another key requisite to promote long-term stability of liquid formulations in pre-filled syringes.

Designed formulations’ syringe-ability is measured directly in-system mimicking the typical administration procedure of the patient.

In case stability in aqueous solution is found to be limited by the biologic ́s inherent sensitivity, freeze-drying clears the way forward. Innovative design of lyo-formulations and freeze-drying processes developed by ProJect Pharmaceutics reliably overcome the hurdles of reconstituting high-concentrated protein lyophilizates.
