  • Publication number: 20190262417
    Abstract: The invention provides methods for obtaining compositions having antibody drug conjugates (ADCs) with specified drug to antibody ratios (DARs). Included in the invention is a method for purifying an ADC mixture having ADCs with a drug loaded species of 6 or more by contacting the mixture with a hydrophobic resin such that a composition comprising less than 15% of the 6 or more drug loaded species is obtained. The invention also provides a composition wherein 70% or more of the ADCs present have a drug loaded species of 4 or less, wherein the ADC comprises an anti-EGFR antibody and an auristatin.

  • Publication number: 20120028908
    Abstract: A process for preparing a crystalline rapamycin analog includes: combining the rapamycin analog with an organic medium to form a mixture; incubating the mixture until the rapamycin analog crystallizes; and recovering the crystalline rapamycin analog. The organic medium can be a solvent, and the process can include causing the rapamycin analog to dissolve into the solvent, and incubating the solvent until the rapamycin analog crystallizes. The following can also be performed: forming a slurry of crystalline rapamycin analog; stirring the rapamycin analog mixture until the rapamycin analog crystallizes; saturating the rapamycin analog solution; forming a supersaturated rapamycin analog solution; combining an antisolvent with the rapamycin analog and the solvent to form a biphasic mixture, and incubating the biphasic mixture to cause a liquid-liquid phase split.
