Carrying out intended dosing regimens often require highly concentrated protein formulations that may be too viscous for subcutaneous administration or other routes of administration that are limited by volume. While reducing viscosity with a single excipient can be ineffective or compromising protein stability, our platform featuring combinations of viscosity-reducing agents provides a variety of manufacturing and final formulation benefits.
Our offering comprises:
The Viscosity Reduction Platform comprises six excipients from two functional groups, an amino acid component (L-Arginine, L-Phenylalanine, L-Ornithine monohydrochloride) and an anionic component (Benzenesulfonic acid, Pyridoxine hydrochloride, Thiamine phosphoric acid ester chloride dihydrate). These two components can act in synergy, leading to a superior viscosity reduction in many cases, compared to a single excipient, whilst maintaining protein stability.
The six excipients can be combined in up to nine functional combinations. As every protein is different, it is important to test to find your most promising combination.
Below are the options we offer to test the platform in order to find your most promising combination.
