摘要:
The present invention provides methods for producing a lyophilized degarelix product which, upon reconstitution with water for injection in an amount of 20 mg/ml, shows a viscosity of up to 15 mPas. The present invention also provides a lyophilized degarelix drug substance which shows, upon dissolution in water in an amount of 20 mg/ml, a viscosity of up to 3.2 mPas, and processes for providing this lyophilized degarelix drug substance.

摘要:
The present invention relates to a liquid (or solution)-phase manufacturing process for preparing the decapeptide Degarelix, its protected precursor, and other useful intermediates. The invention further relates to polypeptides useful in the solution-phase manufacturing process and to the purification of Degarelix itself. Degarelix can be obtained by subjecting a Degarelix precursor according to formula II: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ (P 1 )AA 1 -AA 2 -AA 3 -AA 4 (P 4 )-AA 5 -AA 6 (P 6 )-AA 7 -AA 8 (P 8 )-AA 9 -AA 10 -NH 2 €ƒ€ƒ€ƒ€ƒ€ƒ(II) or a salt or solvate thereof, to a treatment with a cleaving agent in an organic solvent, wherein P 1 is an amino protecting groups; preferably acetyl; P 4 is hydrogen or a hydroxyl protecting group, preferably a hydroxyl protecting group; P 6 is hydrogen or an amino protecting groups; preferably an amino protecting groups; and P 8 is an amino protecting group.
