  • Publication number: 20230330184
    Abstract: This disclosure provides a method of preventing, alleviating or treating a condition (i.e., neutropenia) in a subject in need thereof, the condition characterized by compromised white blood cell production in the subject. The method includes administering to the subject a therapeutically effective amount of a protein complex on the same day as a chemotherapy regimen, wherein the protein complex is a modified human granulocyte-colony stimulating factor (hG-CSF) covalently linked to an immunoglobulin Fc region via a non-peptidyl polymer. The non-peptidyl polymer is site-specifically linked to an N-terminus of the immunoglobulin Fc region, and the modified hG-CSF comprises substitutions in at least one of Cys17 and Pro65.

  • Patent number: 9713616
    Abstract: Compositions comprising a calcium salt of L-leucovorin may be prepared that have a higher concentration of L-leucovorin than may be prepared using racemic leucovorin under similar conditions. Thus, some pharmaceutical compositions described herein may comprise a calcium salt of L-leucovorin at a relatively high concentration, such as at least about 15 mg/mL. Such a composition may be a stable aqueous solution, and may have near physiological pH, such as about 6 to about 8. Some pharmaceutical compositions may be substantially free of D-leucovorin, and may contain either: a) no EDTA, or b) less than about 1 mg/ml of EDTA. These compositions may be prepared, for example, by sonicating a mixture comprising the solid calcium salt of L-leucovorin and water. In some compositions, a calcium salt of L-leucovorin may be sufficiently soluble that it does not precipitate when it is injected.
