摘要:
Method of manufacturing a dry composition comprising a therapeutically effective amount of a rhGH polymer prodrug and one or more lyoprotectants, wherein the growth hormone is transiently bound to a polymer carrier, the rhGH polymer prodrug having the chemical structure shown in (A), in which HN-rhGH represents the rhGH residue attached to the transient linker; R1, R2, R3, R4 and R5 are independently selected from hydrogen, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, tertiary butyl; PEG is a water soluble polyethylene glycol polymer containing at least 50% by weight of ethylene oxide units attached to the transient linker; n>; = 1 or 2; and X is selected from C1 to C8 alkyl or C1 to C12 heteroalkyl; The method comprising the steps of (i) mixing the rhGH polymer prodrug with trehalose dihydrate and succinic acid to produce a composition comprising rhGH polymer prodrug 10-300 mg / ml succinic acid 5-50 mM trehalose dihydrate 25-850 mg / ml, (ii) adjust the pH of the composition of step (i) to a pH ranging from pH 4.5 to pH 5.5 with tris, (iii) transfer amounts of the mixture from step (i ) equivalent to the desired number of dosages to suitable chambers of a container, (iv) drying the mixture and (v) sealing the container; the order of stages (ii) and (iii) can be changed.Método de fabricación de una composición seca que comprende una cantidad terapéuticamente eficaz de un profármaco de polímero de rhGH y uno o más lioprotectores, en el que la hormona de crecimiento está unida transitoriamente a un portador de polímero, teniendo el profármaco de polímero de rhGH la estructura química mostrada en (A), en la que HN-rhGH representa el residuo de rhGH unido al enlazador transitorio; R1, R2, R3, R4 y R5 se seleccionan independientemente de hidrógeno, metilo, etilo, propilo, isopropilo, butilo, isobutilo, butilo terciario; PEG es un polímero de polietilenglicol soluble en agua que contiene al menos 50 % en peso de unidades de óxido de etileno unidas al enlazador tr
