TABLE 3 test results of the influence of pH, excipients, and dosage forms on protein purity
As can be seen from the results of Table 3 and FIG. 1, the SEC purity and IEC purity of 1-9 and 1-10 are significantly superior to those of the other groups, indicating that the lyophilized preparation has better stability than the injection; as can be seen from the results of IEC purity, 1-4, 1-5, 1-6, 1-7 and 1-8 are superior to 1-1, 1-2 and 1-3 except for the freeze-dried group, indicating that the lower pH value is not favorable for the IEC purity; the difference between the two groups 1-1 and 1-2 is small, which shows that the influence of different polysorbate 80 contents is not obvious, and 0.2-2.0mg/ml meets the requirement. 1-8 and 1-7 are not obvious in difference, which indicates that the concentration of the protein 80mg/ml is not obvious in difference with the concentration of the protein 30mg/ml, and the protein is subpackaged into 1.0-5.3ml according to 2-20ml penicillin bottles, and the dosage can be 30-420 mg/bottle; the differences of the groups 1-4, 1-5, 1-6 and 1-7 are not obvious, which shows that the histidine-histidine hydrochloride buffer solution and the phosphate buffer solution have no obvious difference and are superior to the acetate buffer solution; 1-9 and 1-10 did not differ significantly, indicating that there was no significant difference between sucrose and trehalose.
Example 2 DOE investigation of pH, surfactants
In this example, the pH and the polysorbate 80 amount were examined by DOE design, the pH was set to 5.2-6.2, and the polysorbate 80 content was set to 0.01-1.0 mg/ml. The protein content is 40mg/ml, histidine-histidine hydrochloride buffer solution is 20mM, and the dosage of trehalose is 40 mg/ml. The filling volume is 1ml, and the dosage is 40 mg/bottle (solution). 10 groups of formulations were placed at 40 ℃ for 4 weeks and sampled for SEC purity, IEC purity, insoluble particles at 0, 1, 2, 3, 4 weeks, respectively.
TABLE 4 DOE design formula table
TABLE 5 DOE results
The results of the DOE groups in Table 5 were subjected to linear regression analysis, and the slope of each group was subjected to DOE model analysis using JMP, and the results are shown in FIG. 2. As can be seen from FIG. 2, the shaded area in the figure is the optimal range for screening. The preferred range of pH may be 5.2-6.2 and the preferred amount of polysorbate 80 may be 0.01-1.0mg/ml, wherein a lower range of polysorbate 80 is used when a higher range of pH is used, and a higher range of polysorbate 80 is used when a lower range of pH is used.
Example 3 buffer concentration, protein protectant concentration examination
This example examines the buffer concentration and the concentration of the protein protectant. As shown in Table 6, 5 samples were prepared with a histidine-histidine hydrochloride buffer in the range of 5-20mM, trehalose at 20-40mg/ml, pH 6.0. The samples were prepared and lyophilized at a volume of 5.3ml for a dose of 210 mg/vial, with the lyophilization parameters shown in Table 7. After freeze-drying, the mixture is placed at 40 ℃, and samples are taken at 0, 1, 2, 3 and 4 weeks to detect the SEC purity and the IEC purity.

TABLE 7 examination of buffer, protein protectant lyophilization parameters
TABLE 8 buffer, protein protectant results
As can be seen from the results of Table 8 and FIG. 3, the SEC purity and IEC purity were poor in the 3-1 group and poor in the 3-4 group. The IEC purity of 3-2 groups is the best, and the SEC purity of 3-5 groups is the best. From the above results, it is found that the preferable buffer concentration is 10 to 20mM, and the preferable trehalose concentration is 30 to 40 mg/ml.
Example 4 lyophilization Process investigation
The lyophilization process was examined according to the lyophilization parameters of table 9, respectively. The freeze-dried formulation comprises 40mg/ml of protein, 10mM of histidine-histidine hydrochloride buffer solution, 30mg/ml of trehalose, 800.3 mg/ml of polysorbate and pH 6.0. And 5.3ml of penicillin bottles with the dosage of 210 mg/bottle are adopted for filling. And (5) inspecting the freeze-drying curve and the appearance of the sample after freeze-drying.
TABLE 9 examination of lyophilization Process
As can be seen from the results of FIGS. 4-6, the drying time was insufficient for the 4-1 lyophilization curve, the product curve did not intersect the temperature line of the sheet layer, which may result in incomplete sublimation of water, while the 4-2 and 4-3 curves meet the requirement, with the 4-2 intersection occurring at about 1020min (17h) at the earliest, indicating a main drying time of at least 17 h. The appearance of the three freeze-dried samples meets the requirements. Thus, preferred lyophilization parameter conditions are as follows: putting the mixture into a box at 5 ℃, and pre-freezing the mixture for 3 hours at the temperature of minus 40 ℃; the main drying temperature is-15 to-20 ℃, the vacuum degree is 200 to 300 mu bar, and the time is more than 17 hours; drying for 5-10 h at 0-15 ℃ and 100-300 μ bar vacuum degree; final drying at 30 deg.C under 60 μ bar for 4 h.

TABLE 11 stability results
As can be seen from the results in Table 11, the SEC purity and IEC purity varied little after standing at 25 ℃ for 6 months and met the quality standard requirements. As can be seen from the results in Table 11 and FIG. 7, there was no significant change in SEC purity after 6 months at 5 ℃ and the drug expiration date calculated for IEC purity according to the ICH guidelines was 91 months.
