[0107] Lyophilized formulation of humanized anti-IL-23p19 antibody.
[0108] Lyophilized formulations of humanized anti-IL-23p19 antibodies were prepared as follows. Table 3 provides the batch formula of the humanized anti-IL-23p19 antibody. The final concentration of humanized anti-IL-23p19 antibody was 25 mg / mL. This batch formulation can be used to prepare lyophilized 50 mg / vial units as described in Table 4 below. Uses polysorbate-80 from plant sources. Additional citric acid or sodium hydroxide can be added to adjust the pH to the desired value of about 4.8 (±0.2). Use pH 4.8 to reduce opalescence when antibodies are reconstituted from pH 5.5-5.6 citrate buffer. Use Sterile Water for Injection (WFI) to bring the ingredients to a final volume of 40 L. Of course, correspondingly smaller batches could be prepared by proportionally reducing the amounts listed in Table 3.

[0129] Stability testing of lyophilized preparations of humanized anti-IL-23p19 antibody.
[0130] Figure 2-7 The test results of the stability of the lyophilized preparation of the humanized anti-human IL-23p19 antibody under different storage conditions are provided. Some vials are stored in upright and inverted configurations, as shown in the figure. As described in more detail below, Figure 2-4 demonstrated stability of at least 18 months for antibodies lyophilized at pH 5.5 (citrate buffer), Figure 5-7 Antibodies lyophilized at pH 4.8 (citrate buffer) were shown to have a stability of at least 12 months, with 18 and 12 months being the longest time points shown and not the stability endpoints determined by the assay.
[0131] Stability was evaluated as follows. Samples were lyophilized in 5 mL Type I glass vials, sealed with 13 mm bromobutyl lyophilization stoppers (Helvoet Rubber & Plastic Technologies BV, Hellevoetsluis, The Netherlands) and aluminum snap-off cap...
