摘要： A fusion protein having a non-immunoglobulin polypeptide having a cysteine residue proximal to the C terminal thereof, and an immunoglobulin component with a mutated hinge region is provided. The mutation comprises a point mutated site corresponding in position to the position in a native hinge region of the cysteine residue located nearest the cysteine residue of the non-Ig component. The distance from the cysteine residue of the non-immunoglobulin polypeptide and any remaining cysteine residues of the mutated hinge region is sufficient to prevent the formation of a disulphide bond therebetween.

摘要： A recombinant fusion protein comprising a human erythropoietin peptide portion linked to an immunoglobulin peptide portion is described. The fusion protein has a prolonged half-life in vivo compared to naturally occurring or recombinant native human erythropoietin. In one embodiment, the protein has a half-life in vivo at least three-fold higher than native human erythropoietin. The fusion protein exhibits enhanced erythropoietic bioactivity compared to native human erythropoietin. In one embodiment, the fusion protein comprises the complete peptide sequence of a human erythropoietin (EPO) molecule and the peptide sequence of an Fc fragment of human IgG1, which Fc fragment includes the hinge region, CH2 and CH3 domains. The EPO molecule may be linked directly to the Fc fragment to avoid extraneous peptide linkers and lessen risk of an immunogenic response when administered. In one embodiment the hinge region is a human Fc fragment variant having a non-cysteine residue at amino acid 6.

For each of the one or more predictor variables, an imputation model is built based on information of a target variable; a type of imputation model to construct is determined based on the one or more data sources, a measurement level of the predictor variable, and a measurement level of the target variable; and the determined type of imputation model is constructed using basic statistics of the predictor variable and the target variable. The missing value is imputed for each of the one or more predictor variables using the data from the one or more data sources and one or more built imputation models to generate a completed data set.
