Abstract
The invention provides novel compositions of bioactive polypeptides and proteins with improved stability and shelf-life. The compositions are based on liquid vehicles selected from semifluorinated alkanes. These vehicles are remarkably effective in protecting polypeptides and proteins from degradation and/or aggregation. The compositions are useful for topical administration, e.g. into an eye, or by parenteral injection, e.g. via the subcutaneous or intramuscular route.
Claims18
Composition comprising a bioactive compound and a liquid vehicle, wherein the liquid vehicle comprises a semifluorinated alkane of the formula
- RFRH
- wherein RF is a linear perfluorinated hydrocarbon segment with 4 to 12 carbon atoms, and wherein RH is a linear alkyl group with 4 to 8 carbon atoms;
- and wherein the bioactive compound is a therapeutic or diagnostic agent or vaccine selected from polypeptides and proteins and is incorporated in the composition such as to form a dispersion or suspension.
Method of preparing a composition comprising a bioactive therapeutic or diagnostic agent or vaccine selected from a polypeptide or protein, comprising the step of incorporating the bioactive polypeptide or protein within a liquid vehicle which comprises a semifluorinated alkane of the formula
- RFRH
- wherein RF is a linear perfluorinated hydrocarbon segment with 4 to 12 carbon atoms, and wherein RH is a linear alkyl group with 4 to 8 carbon atoms such as to form a dispersion or suspension.
