摘要:
The present invention provides compositions of Ig fusion proteins, especially compositions including an Ig fusion protein, a bulking agent, a disaccharide, a surfactant, and a buffer. In one aspect, these compositions are stable under long-term storage or at least one freeze/thaw cycle. The invention also provides methods of preparation of the Ig fusion protein compositions. In one aspect, compositions of the invention are lyophilized. In a further aspect, the compositions are lyophilized by a process that includes an annealing step.
摘要:
Hemophilia treatment by the inhalation of coagulation factors. Dry powder Factor IX is aerosolized to a mass median aerodynamic diameter of 4 μm or less, with at least 90% monomer content, at least 80% activity level, and 10% water or less. The aerosol is slowly, and deeply inhaled into the lung, and followed by a maximal exhale.
摘要:
Human antibodies, preferably recombinant human antibodies, that specifically bind to human interleukin-12 (hIL-12) are disclosed. Preferred antibodies have high affinity for hIL-12 and neutralize hIL-12 activity in vitro and in vivo. An antibody of the invention can be a full-length antibody or an antigen-binding portion thereof. The antibodies, or antibody portions, of the invention are useful for detecting hIL-12 and for inhibiting hIL-12 activity, e.g., in a human subject suffering from a disorder in which hIL-12 activity is detrimental. Nucleic acids, vectors and host cells for expressing the recombinant human antibodies of the invention, and methods of synthesizing the recombinant human antibodies, are also encompassed by the invention.
摘要:
Methods of formulating proteins at high concentrations in protein solutions, wherein the protein solutions lack or have reduced liquid-liquid phase separation are described. Such protein solutions are substantially clear and substantially homogenous. Additionally, methods of concentrating and purifying proteins using liquid-liquid phase separation are provided.
摘要:
The present invention provides formulations for maintaining the stability of Aβ binding polypeptides, for example, Aβ antibodies. Exemplary formulations include a tonicity agent such as mannitol and a buffering agent or amino acid such as histidine. Other exemplary formulations include an antioxidant in a sufficient amount as to inhibit by-product formation, for example, the formation of high molecular weight polypeptide aggregates, low molecular weight polypeptide degradation fragments, and mixtures thereof. The formulations of the invention optionally comprise a tonicity agent, such as mannitol, and a buffering agent or amino acid such as histidine. The formulations are suitable for several different routes of administration.

摘要:
The present invention provides, among other things, stable formulations for small modular immunopharmaceutical (SMIP™) proteins. In some embodiments, the present invention provides a formulation containing a lyophilized mixture of a small modular immunopharmaceutical protein, wherein less than 7% of the lyophilized small modular immunopharmaceutical protein exists in aggregated form. Formulations according to the invention may contain buffering agents, stabilizers, bulking agents, surfactants and/or other excipients. The present invention also provides formulations for lyophilization, reconstitution and methods of use thereof.
摘要:
The present invention provides methods of lyophilizing a pharmaceutical substance involving a primary drying step executed at a product temperature at or above the collapse temperature. The invention also provides pharmaceutical substances lyophilized at or above the collapse temperature.
摘要:
Methods of reducing aggregation of a protein or proteins in a formulation, and protein formulations having reduced aggregation properties are provided. The methods and formulations described herein maintain the biological activity of a protein and increase the shelf life of protein formulations.
