摘要:
The invention relates to a liquid, aqueous pharmaceutical composition comprising a Factor VII polypeptide (e.g. human Factor VIIa) and buffering agent; wherein the molar ratio of non-complexed calcium ions (Ca2+) to the Factor VII polypeptide is lower than 0.5. The composition may further comprise a stabilizing agent (e.g. copper or magnesium ions, benzamidine, or guanidine), a non-ionic surfactant, a tonicity modifying agent, an antioxidant and a preservative. The composition is useful for treating a Factor VII-responsive syndrome, such as bleeding disorders, including those caused by clotting Factor deficiencies (e.g. haemophilia A, haemophilia B, coagulation Factor XI deficiency, coagulation Factor VII deficiency); by thrombocytopenia or von Willebrand's disease, or by clotting Factor inhibitors, and intra cerebral haemorrhage, or excessive bleeding from any cause. The preparations may also be administered to patients in association with surgery or othe trauma or to patients receiving anticoagulant therapy.
摘要:
The present invention relates to a purification process for drug substances of a Factor VII polypeptide having an impurity in the form of desGla-Factor VII polypeptide structures. The process utilizes an anion-exchange material and includes washing and/or elution with a buffer of a predetermined pH.
摘要:
The present invention relates to novel antibodies against FVII, use for determining amount of correctly folded and intact FVII in a sample, as well as for purification and process optimization.
摘要:
The present invention relates to Vitamin K-dependent protein compositions having a very low, or negligible, content of protein contaminants. The present invention also relates to method applicable in the preparation of such Vitamin K-dependent protein compositions. Such methods may either be used alone or in sequential combination with the purpose of reducing the relative content of protein contaminants. The present invention is particularly relevant in the preparation of compositions of coagulation factors selected from Factor X polypeptides (FX/FXa), Factor IX polypeptides (FIX/FIXa), Factor VII polypeptides (FVII/FVIIa), and the anticoagulant Protein C, in particular Factor VII polypeptides.
