Stabilising formulation for immunoglobulin G compositions in liquid form and in lyophilised form
This invention is related to a stabilizing formulation for immunoglobulins G compositions comprising a sugar alcohol, glycine and a non-ionic detergent, which is suitable for the stabilization of immunoglobulins G compositions in liquid form and in lyophilized form. The invention also relates to an immunoglobulins G composition in liquid form or in lyophilized form comprising said stabilizing formulation.
1. A stabilizing formulation consisting of mannitol, glycine and a non-ionic detergent, suitable for the stabilisation of an immunoglobulin G composition in liquid form and in lyophilised form, wherein the concentration of mannitol is between 30 g/l and 50 g/l, and wherein the concentration of glycine is between 7 g/1 and 10 g/l.
2. An immunoglobulin G composition in liquid form, consisting of immunoglobulins G, water and the stabilising formulation according to claim 1 .
3. An immunoglobulin G composition in lyophilised form, consisting of immunoglobulins G and the stabilising formulation according to claim 1 .
4. The immunoglobulin G composition according to claim 2 , wherein the composition includes an amount of polymers less than 0.3% after a 6 months storage period at room temperature.
5. The immunoglobulin G composition according to claim 3 , wherein the composition includes an amount of polymers less than 0.3% after a 12 months storage period at room temperature of for 6 months at 40° C.
6. The immunoglobulin G composition according to claim 1 , wherein the composition includes an amount of dimers less than 7% after a 24 months storage period at 4° C.
