Description

Application of pharmaceutical composition in preparation of melanoma treatment products
Technical Field
The invention belongs to the field of medicines, and particularly relates to an application of a pharmaceutical composition comprising LAG-3 monoclonal antibody and sirolimus or a pharmaceutical preparation containing the pharmaceutical composition in preparation of a melanoma treatment product.
Background
Patients with advanced malignant tumor have short life cycle and poor life quality, and the adoption of drug treatment is the main treatment method for most patients with advanced tumor. The traditional antitumor drugs are combined chemotherapy by adopting a plurality of cytotoxic drugs, the chemotherapy drugs have poor targeting property and obvious side effects, and have great damage to normal tissue cells while killing tumor cells, so that great clinical demands for novel antitumor drugs exist.
In recent years, tumor immunotherapy is becoming a research and development hotspot, and a great breakthrough is continuously obtained. Different from the traditional chemotherapeutic drugs which directly kill or inhibit the action mechanism of tumor cells, the tumor immunotherapy is to activate the human body autoimmune system to identify and kill the tumor cells by improving the functions and activities of the body immune system, so that the tumor immune therapy is more in line with the functions of the human body and has smaller adverse reaction. Tumor immunotherapy has become a hotspot in the field of tumor therapy today, where T cell tumor immunotherapy is in the core position.
LAG-3 belongs to immunoglobulin superfamily, and is composed of three parts of extracellular region, transmembrane region and cytoplasmic region, and is mainly expressed on the surface of activated T lymphocyte and partial natural killer cell, etc., and can negatively regulate and control body immunity function. Numerous studies have demonstrated that by inhibiting the binding of LAG-3 to its ligand molecules, T cell activation and killing of tumor cells by the immune system can be promoted, LAG-3 has become a potential tumor immunotherapeutic target and provides a potential route for tumor immunotherapy in addition to CTLA-4, pd-1.
LAG-3 and PD-L1/PD-1 both negatively regulate T cell function. Sequencing results of various tumor tissues (including 1400 cases of breast cancer, colon cancer, lung cancer and the like) show that the PD-L1 gene is highly expressed and has positive correlation with the LAG-3 gene, which indicates that the two genes are simultaneously expressed in tumor patients, and in addition, research shows that the PD-1 protein is highly expressed on the surface of TIL cells in non-small cell lung cancer patients and has positive correlation with the LAG-3 protein expression; these two negative regulatory T cell functional proteins (LAG-3 and PD-L1/PD-1) co-express and synergistically inhibit T cell function, resulting in a poor prognosis for the patient. The above studies clearly show the feasibility and potential synergistic efficacy of targeting both PD-1/PD-L1 and LAG-3 as therapeutic approaches.
Malignant melanoma is a tumor produced by melanocytes of skin and other organs, belongs to a high-grade malignant tumor, is one of the most rapid malignant tumors with high incidence rate in recent years, has high malignancy degree, early metastasis occurrence and high death rate, and therefore has an unmet clinical treatment demand.
In summary, aiming at the clinical rigid treatment requirement of melanoma, a novel safe and effective antibody drug for resisting LAG-3 target spot is developed, and particularly, the PD-1/PD-L1 inhibitor is combined, so that the problems of low effective rate, drug resistance and the like of the PD-1/PD-L1 inhibitor can be further improved, and the novel antibody drug is one of important ways for further improving the curative effect of melanoma.

Detailed Description
The experimental methods described in the following examples are all conventional methods unless otherwise specified; the reagents and materials, unless otherwise specified, are commercially available.
EXAMPLE 1 in vivo experiments in mice of the inhibition of melanoma growth by the fully human anti-LAG-3 monoclonal antibody GLS-012 and the fully human anti-PD-1 Silapachob 1:1 composition
1. Purpose(s)
Compared with the composition of the prior art of the mixture ratio of the anti-LAG-3 and the anti-PD-1 target drug Relalimab+Nivolumab 1:3, the anti-melanoma effect and the mixture ratio advantage of the composition of the fully human anti-LAG-3 monoclonal antibody GLS-012 and the fully human anti-PD-1 siroli monoclonal antibody 1:1 are explored.
2. Method of
2.1 PBS-resuspended melanoma cells B16F10 were inoculated subcutaneously in the right flank of female B6-hLAG-3 mice and grown to 74mm in tumors 3 Left and right time group dosing, total 4 groups of 8 animals each, goup1 (negative control): isotype control hIgG4 20mg/kg; goup2 (positive control 1:3 ratio group): relalimab 20mg/kg+Nivoluamb 60mg/kg; goup3 (experimental 1:3 proportioning): fully human anti-GLS-012 20 mg/kg+Zimbereliamb 60mg/kg; goup4 (experimental group 1:1 proportioning group): fully human anti-GLS-012 20 mg/kg+Zimbereliamb 20mg/kg.
The administration volume was 10. Mu.L/g based on the animal body weight. Grouping when the astronomical was D0, 2 doses per week for 4 times total, for relative Tumor Growth Inhibition (TGI) RTV ) Evaluation was performed. Wherein, the positive control drug analogues, relatlimab and Nivoluamb, are anti-LAG-3 and anti-PD-1 monoclonal antibodies marketed in the first global lot, respectively.
2.2 Relative tumor growth inhibition rate TGI RTV (%) = (1-T/C) ×100%, wherein: T/C = treatment/control RTV mean, RTV is relative tumor volume, i.e. TV ratio after treatment to before treatment.
3. Results
3.1 Safety of
The mice can normally ingest drinking water in a general state after administration, and besides obvious weight reduction of Goup3 mice, the other groups are stable in body weight without stopping administration and death. It is suggested that the other proportioning dose groups have no obvious adverse reaction except that Goup3 can cause the obvious reduction of the weight of the mice due to the adverse reaction. The weight change curves of the mice in each group are shown in figure 1.
3.2 Effectiveness of the method
Compared with the negative control group, the composition groups with various proportions have obvious effect of inhibiting the growth of melanoma cells, and have the effect of inhibiting the tumor growth rate TGI RTV (%) was Goup2:61%, goup3:88%, goup4:84% compared to the negative control groupPAre all<0.01. Second, goup compared to the Goup2 positive drug 1:3 composition3. Goup4 has stronger tumor inhibition activity, but compared with two groups of Goup3 and Goup4, the tumor inhibition rates have no obvious differenceP>0.05 See fig. 3 for details). The two groups of the GLS-012+saparlizumab 1:3 and 1:1 ratio composition have close curative effects, but the 1:1 ratio composition has obviously better safety and lower dosage. The relevant data experiments are shown in table 1 and fig. 2 and 3. The results of this study show that the therapeutic effect of the composition of different proportions of GLS-012 and sirolimus does not increase linearly with increasing dose, possibly related to the saturation of T lymphocyte receptor occupancy at a given dose.

Note that: data = mean ± standard deviation; comparison with negative control groupP<0.01; compared with the positive control group, the #P<0.05。
4. Conclusion(s)
From the above, it is clear that the fully humanized anti-LAG-3 monoclonal antibody GLS-012 combined anti-PD-1 sapalizumab 1:3 composition and the 1:1 ratio composition have the effect of remarkably inhibiting the growth of melanoma, wherein the 1:1 ratio composition has the similar curative effect as the 1:3 ratio composition, but has better safety, lower using dosage and more clinical application advantages.
