Pre-filled pharmaceutical package comprising a liquid formulation of a VEGF-antagonist

A pre-filled pharmaceutical package comprising a liquid formulation of a VEGF-antagonist, wherein the pre-filled pharmaceutical package comprises:

• a wall comprising a cyclic olefin polymer, having an interior surface enclosing at least a portion of a lumen;
• a tie coating or layer on the wall interior surface comprising SiOxCyHz, in which x is from about 0.5 to about 2.4 as measured by X-ray photoelectron spectroscopy (XPS), y is from about 0.6 to about 3 as measured by XPS, and z is from about 2 to about 9 as measured by at least one of Rutherford backscattering spectrometry (RBS) or hydrogen forward scattering (HFS);
• a barrier coating or layer of SiOx, in which x is from about 1.5 to about 2.9 as measured by XPS, the barrier coating or layer positioned between the tie coating or layer and the lumen;
• a pH protective coating or layer of SiOxCyHz, in which x is from about 0.5 to about 2.4 as measured by XPS, y is from about 0.6 to about 3 as measured by XPS, and z is from about 2 to about 9 as measured by at least one of RBS or HFS, positioned between the barrier coating or layer and the lumen;
• a lubricity coating or layer positioned between the pH protective coating or layer and the lumen, wherein the lubricity coating or layer has the atomic proportions SiOxCyHz, in which x is from about 0.5 to about 2.4 as measured by XPS, y is from about 0.6 to about 3 as measured by XPS, and z is from about 2 to about 9 as measured by at least one of RBS or HFS;
• a liquid formulation of a VEGF-antagonist in the lumen;
• and
• a closure closing the lumen;
• wherein the VEGF antagonist is Ranibizumab.
