Abstract:
The present invention provides stable pharmaceutical compositions or formulations, including solution and non-solution phase formulations, and methods of preparing the same. The formulations of the invention may improve the stability and/or solubility of various pharmaceutically-active ingredients, including biological molecules and small drug compounds, and may be tailored to a variety of storage conditions. The formulations of the invention may provide an alternative to lyophilization, or may be employed together with lyophilization or other methods of stabilization. Generally, the compositions comprise a pharmaceutically active ingredient, such as a biological molecule or small drug compound, and a pharmaceutically acceptable carrier. The carrier comprises an Elastin-Like Peptide (ELP) in an amount and form (e.g., soluble or insoluble form) effective for stabilizing the pharmaceutically active ingredient.
Abstract:
The present invention discloses fusion proteins comprising a transferrin moiety and a melanocortin or melanocortin receptor agonist moiety. In one embodiment of the invention, the transferrin moiety is modified to exhibit reduced or no glycosylation. In another embodiment, the transferrin moiety is modified to exhibit reduced or no binding to a transferrin receptor. The fusion protein of the invention can optionally comprise a linker peptide and/or a second therapeutic peptide such as GLP-1 or exendin-4. Also disclosed are methods of treating or preventing a disease or condition in a subject by administering a fusion protein of the invention.
Abstract:
Modified fusion proteins of a transferrin moiety, a GLP-1 moiety and a linker moiety, with increased productivity, bioactivity and serum half-life are disclosed. Preferred fusion proteins include those modified so that the transferrin moiety exhibits no or reduced glycosylation. The fusion proteins of the invention are useful for the treatment of Type 2 diabetes, Type 1 diabetes, obesity, congestive heart failure, and non-fatty liver disease.
Abstract:
EPM peptides, including EPM peptide-fusion proteins with increased serum half-life or serum stability are disclosed. Compositions comprising the EPM peptides or fusion proteins and methods of treating or preventing disorders by administering a therapeutically or prophylactically effective amount of an EPM peptide or fusion protein to a patient in need thereof are also disclosed.
Abstract:
The present invention provides modified Vasoactive Intestinal Peptides (VIPs), encoding polynucleotides and vectors, as well as pharmaceutical compositions comprising the same. The invention further provides methods of making and using the modified VIP agents. In accordance with the invention the VIP exhibits an extended circulatory half-life, receptor-binding or biological potency, and/or altered receptor binding profile with respect to unmodified VIP.
Abstract:
The invention provides fusion proteins comprising an exendin-4 fused to a transferrin (Tf) via a polypeptide linker, as well as corresponding nucleic acid molecules, vectors, host cells, and pharmaceutical compositions. The invention also provides the use of the exendin-4/Tf fusion proteins for treatment of Type Il diabetes, obesity, and to reduce body weight.
Abstract:
Fusion proteins of transferrin and IFNβ with increased serum half-life or serum stability are disclosed- Preferred fusion proteins include those modified so that the transferrin moiety exhibits no or reduced glycosylation, binding to iron and/or binding to the transferrin receptor.
Abstract:
Modified fusion proteins of transferring and therapeutic proteins or peptides including, with increased serum half-life or serum stability are disclosed. Preferred fusion proteins include those modified so that the transferrin moiety exhibits no or reduced glycosylation, binding to iron and/or binding to the transferrin receptor.
Abstract:
The present invention provides modified therapeutic polypeptides or peptides partially or completely protected from DPP activity. The modified polypeptides or peptides comprise at least one additional amino acid at the amino terminus. The modified therapeutic polypeptides or peptides are useful in the treatment of diseases such as diabetes.
Abstract:
Pharmaceutical compositions containing modified fusion proteins of transferrin and therapeutic proteins or peptides with increased serum half-life or increased serum stability are disclosed. Preferred fusion proteins include those modified so that the transferrin moiety exhibits no or reduced glycosylation, but does exhibit binding to iron and/or the transferrin receptor. Such fusion proteins may be administered orally.
