Large scale production and characterization of lyophilized pyridoxalated hemoglobin-polyoxyethylene (PHP).
Lyophilized PHP as an oxygen carrier is prepared from outdated red cell and dicarboxymethylated polyoxyethylene. In order to apply PHP for a clinical use, a large scale production of high quality PHP has been studied. We have set up a 20 L scale production flow of PHP88. The product was tested to confirm the quality and lot-to-lot consistency. The blood group specific materials were weakly positive in stroma-free hemoglobin (SFH), however, were found negative in the PHP of this scale. The amount of phosphatidylethanolamine (PE) in purified SFH and PHP88 reconstituted solution was 0.19 +/- 0.04 and 0.03 +/- 0.01 ppm, respectively. Contamination of viruses such as HBV and Non A non B hepatitis virus could not be observed in the final product. Elimination and inactivation of HIV was validated through a spike test. The characterizations of the final products in 20 L scale were done through MW, P50, Hill coefficient, viscosity, and molecular weight distribution by SDS-PAGE and batch to batch consistency was also confirmed. The results show that production process is appropriate to eliminate the blood group materials, PE and virus, and produce PHP of high quality. Lyophilized PHP88 can be produced by addition of maltose and can be stored over 1 year.
