Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of molecular biology and medicine, in particular, the present application relates to a recombinant long-acting human growth hormone fusion protein and a preparation method and use thereof, more particularly, the present application relates to an Fc mutant, a fusion protein, a nucleic acid molecule, an expression vector, a recombinant cell, a pharmaceutical composition and use thereof. BACKGROUND
[0002] Growth hormone deficiency is a recognized clinical syndrome associated with a number of metabolic abnormalities, including abnormal body composition, decreased physical performance, altered lipid metabolism, decreased bone mass, increased insulin resistance, and reduced quality of life. Most of the metabolic abnormalities associated with growth hormone deficiency can be reversed by recombinant human growth hormone (rhGH) replacement. Traditional growth hormone deficiency treatment includes daily subcutaneous injection of rhGH, but this treatment method is relatively cumbersome and requires daily injection, which is not convenient for many patients, which raises concerns about poor treatment compliance, which can lead to reduced efficacy. Long-acting rhGH formulations or long-acting growth hormone formulations not only reduce the number of injections and improve compliance, but also help improve the efficacy of GH treatment.
[0003] Therefore, there is still an urgent need to develop a new fusion protein for effective treatment of growth hormone deficiency. SUMMARY
[0004] The present application aims to at least partially solve at least one of the technical problems existing in the prior art. To this end, the present application provides an Fc mutant, a fusion protein, a nucleic acid molecule, an expression vector, a recombinant cell, a pharmaceutical composition and use thereof. The Fc mutant of the present application is prone to form a monomer. The fusion protein of the present application has strong stability and can effectively treat growth hormone deficiency.
[0005] The present application is based on the following findings of the inventors:
[0006] The inventors have found through experiments that mutating specific sites of the Fc fragment of wild-type IgG1, for example, at least one of P228Delete, C229Delete, P230Delete, T366R, L368H, P395K, and K409D / K409T, and L351S, M428Y, and K447A, or P228Delete, C229Delete, T366R, L368H, P395K, and K409D or K409T, can enable the Fc fragment in the form of a natural dimer to form an Fc mutant in the form of a monomer after expression. Furthermore, the inventors have further found through experiments that using the above Fc mutant to link with growth hormone can form a fusion protein in the form of a monomer, which can be purified by Protein A, simplifying the purification process, and the subsequent purification process is simple. Meanwhile, more importantly, the fusion protein has stronger human growth hormone receptor binding activity, cell proliferation promoting activity, and luciferase activity promoting activity of reporter gene cell expression, as well as a longer half-life and better in vivo biological activity.
[0007] To this end, in a first aspect of the present application, the present application provides an Fc mutant.

[0140] It is to be understood by those skilled in the art that the monomeric or dimeric form of the Fc mutant determines the monomeric or dimeric form of the fusion protein formed by the Fc mutant.
[0141] The present application provides an Fc mutant, a fusion protein, a nucleic acid molecule, an expression vector, a recombinant cell, a pharmaceutical composition, and uses thereof, which will be described in detail below, respectively.
[0142] Fc mutant
[0143] In one aspect of the present application, the present application provides an Fc mutant. According to an embodiment of the present application, there is provided a first peptide segment having mutations at at least one of positions 228, 229, 230, 366, 368, 395 and 409, and positions 351, 428 and 447; or positions 228, 229, 366, 368, 395 and 409, compared to a wild-type IgG1 Fc fragment.
[0144] The inventors have found through a large number of experiments that the above mutations are beneficial to express the Fc fragment in a native dimer form to form an Fc mutant in a monomer form, and the Fc mutant in the monomer form is fused with a bioactive molecule, and the subsequent Protein A purification is simplified, and the purification process is simplified; in addition, the fusion protein prepared by using the Fc mutant has higher in vivo and in vitro activity and lower ADCC and CDC effects.
[0145] According to an embodiment of the present application, the first peptide segment has mutations at at least one of positions 228, 229, 230, 366, 368, 395 and 409, and positions 351, 428 and 447; or positions 228, 229, 230, 351, 366, 368, 395, 409 and 428; or positions 228, 229, 230, 351, 366, 368, 395, 409, 428 and 447, compared to a wild-type IgG1 Fc fragment. Thus, the above mutations can form an Fc mutant in a monomer form.
[0146] According to an embodiment of the present application, the first peptide segment has mutations at at least one of positions T366R, L368H, P395K and K409D or K409T; and L351S, M428Y and K447A, compared to a wild-type IgG1 Fc fragment. Thus, the above mutations can form an Fc mutant in a monomer form.
[0147] According to an embodiment of the present application, the first peptide segment has mutations at the following positions compared to the Fc fragment of wild-type IgGl: 1) P228 Delete, C229 Delete, P230 Delete, T366R, L368H, P395K, K447A, and K409D or K409T; or, 2) P228 Delete, C229 Delete, P230 Delete, L351S, T366R, L368H, P395K, M428Y, and K409D or K409T; or, 3) P228 Delete, C229 Delete, P230 Delete, L351S, T366R, L368H, P395K, M428Y, K447A, and K409D or K409T; or, 4) P228 Delete, C229 Delete, T366R, L368H, P395K, and K409D or K409T. The inventors have found, through extensive experiments, that the Fc mutants in monomeric form described above, when fused to a biologically active molecule, the fusion protein is secreted in monomeric form, and has higher in vitro and in vivo activity and lower ADCC and CDC effects.

[0240] Target cell CHO-K1-PD-L1 / GHR treatment: 2 days before the experiment, the cells were passaged, the supernatant was discarded, the cells were washed with 5 mL of PBS, 1 mL of 0.25% trypsin-EDTA was added, and the cells were digested in a 37 °C incubator for 1 min. Then 6 mL of medium 1 (450 mL F12 medium + 50 mL FBS) was added to terminate the digestion, and the cells were resuspended to a single cell suspension. 5 mL of cell suspension was discarded, 8 mL of medium 1 (450 mL F12 medium + 50 mL FBS) was added, and 120 μL of G418 was added. The concentration of G418 was 600 μg / mL, and the mixture was incubated in an incubator.
[0241] 3. Experimental procedure
[0242] On the first day, the target cells CHO-K1-PD-L1 / GHR were adjusted to a density of 2.0 x 10 5The cells were plated at 50,000 cells / mL, 50 μL / well overnight; the next day, the test sample (i.e., J2 or J18), the positive control Avelumab (PD-L1 antibody, Shanghai Jiebei Biomedical Technology Co., Ltd.), and the negative control Acterma were diluted to 0.1 mg / mL with the differentiation medium (99% F12 medium + 1% FBS) for the first dilution, to 15 μg / mL for the second dilution, and then 3-fold dilution for 7 gradients, 50 μL / well was added to the cell plate, mixed, and placed in a 37°C incubator for a total of 30 min, then the cell plate was removed; 30% complement (containing 70% differentiation medium + 30% complement) was added, 50 μL / well, mixed, and placed in a 37°C incubator for a total of 6 h, then the cell plate was removed and equilibrated at room temperature, One-Glo Luminescent Cell Viability Assay was added, 50 μL / well was added to the cell plate, and the pipette was blown 10 times to mix; after 10 min of lysis at room temperature in the dark, the chemiluminescence signal value was detected by a microplate reader. The results showed that in the CDC experiment, after adding the positive control PD-L1 antibody Avelumab, the negative control IL-6R antibody Acterma, and the SBT123 test sample molecule, the positive control Avelumab induced the human serum complement to have a significant CDC effect on the target cells CHO-K1-PD-L1 / GHR, the negative control Acterma had no CDC effect, and the test sample had no CDC effect.
[0243] Example 9: In vivo biological activity test
[0244] A long-acting in vivo pharmacodynamic study of J2 and J18 fusion proteins was conducted: Four-week-old SPF-grade male SD rats, weighing 60-80g, were selected. Two weeks prior to the experiment, the pituitary gland was surgically removed under clean conditions. A two-week recovery period followed the surgery. Before drug administration, healthy animals whose body weight change was less than ±10% of their pre-operative body weight were selected. The pituitary-removed rats were randomly divided into five groups based on body weight: a model group, a low-dose J2 fusion protein group, a high-dose J2 fusion protein group, a low-dose J18 fusion protein group, and a high-dose J18 fusion protein group; eight rats were in each group. The administration method was subcutaneous injection in the neck. The low-dose J2 fusion protein group received J2 fusion protein at a dose of 9.35 nmol / kg; the low-dose J18 fusion protein group received J18 fusion protein at a dose of 9.35 nmol / kg; the high-dose J2 fusion protein group received J2 fusion protein at a dose of 56.1 nmol / kg; and the high-dose J18 fusion protein group received J18 fusion protein at a dose of 56.1 nmol / kg. The model group received a solvent. Each group received either the above administration or solvent once a week, for a total of two administrations. Each rat was weighed at the same time each day after administration to calculate daily weight changes. The experiment was stopped after 14 days, and the rats were weighed again. Weight gain (g) on a given day after administration was the difference between the animal's weight on that day and its weight before administration. At the end of the experiment, a necropsy was performed to confirm the absence of pituitary remnants in the sella turcica region. The weight gain changes of each group over 14 days were compared, and the results are as follows: Figure 3 As shown, "2#-Low" represents the low-dose J2 fusion protein group, "2#-High" represents the high-dose J2 fusion protein group, "18#-Low" represents the low-dose J18 fusion protein group, and "18#-High" represents the high-dose J18 fusion protein group; 2#-Low vs. model group, p = 0.0083; 2#-High vs. model group, p < 0.0001; 18#-Low vs. model group, p = 0.0030; 18#-High vs. model group, p = 0.0003.
[0245] Depend on Figure 3 The results show that:
[0246] (1) Compared with the model group, both the J2 fusion protein and the J18 fusion protein significantly increased the weight of rats at both low and high doses, indicating that the fusion protein provided by the present invention has good in vivo activity.
[0247] (2) The weight gain in the high-dose group was greater than that in the low-dose group.
[0248] (3) The high-dose group of J18 fusion protein had a more significant effect than the high-dose group of J2.
