Technical Field

The invention relates to a human anti-human TIGIT antibody and application thereof in the field of biomedicine.

Background

Tumor Immunotherapy (Cancer Immunotherapy) is a leading hot area of fundamental and clinical research in tumor therapy in recent years. In 2011, the CTLA-4 inhibitor Ipilimumab (Ipilimumab, also known as "Y drug") was approved for marketing, which exerts an anti-tumor effect by activating a T cell-mediated immune response; thus, a new era of tumor immunotherapy is opened. PD-1/PD-L1 antibodies such as Nivolumab (also called "O drug") and palboclizumab (also called "K drug") were developed in succession since 2014, and have achieved remarkable therapeutic effects, profoundly changing the paradigm of cancer therapy. CTLA-4 drug development facilitators James Allison, american scientists, and molecular discoverer PD-1/PD-L1, Tasuku Honjo, japan scientist, also have acquired a nobel physiology or medical prize in 2018 due to their contribution to "treating cancer by inhibiting negative immune regulation". The success of the first generation Immune Checkpoint Inhibitor (ICB) represented by CTLA-4 and PD-1/PD-L1 monoclonal antibodies not only drives the rapid increase of drug research and development investment, but also promotes the deep research of tumor Immune mechanism and immunotherapy strategy.

At the same time, the intensive search of clinical practice has also gradually revealed the outstanding problems faced by the first generation of immune checkpoint antibodies: beneficial patients haveLimited, poor effect of most tumors, drug tolerance, etc. In the case of PD-1/PD-L1 monoclonal antibody, for most tumor types, only less than 20% of patients actually benefit from treatment; at the same time, a significant fraction of patients with effective early treatment experience tumor recurrence during or after treatment. According to the differences of immunophenotype of Tumor Microenvironment (TME), the current mainstream theory divides tumors into four types of ' hot ' Tumor (inflammatory Tumor), ' cold ' Tumor (immune ' desert), ' immunosuppressive Tumor and ' immune-blocking Tumor ((TM))Galon and Daniela Brunii, nat. Rev. drug Discov.2019,18: 197-218.). Clinical research results show that the response rate of the 'hot' tumor with a large amount of immune cell infiltration in the tumor parenchyma to ICB antibody single drug treatment is high, and the congenital drug resistance probability is low. In addition, the selective pressure developed by immunotherapy remodels the tumor microenvironment, and then evolves a new immunosuppressive mechanism, causing a shift in tumor immunophenotype (immune-altered), which may be one of the important mechanisms for tumor immune escape and drug resistance. In this dilemma, the research focus of academia and industry has focused on three main directions: (1) discovery of a new mechanism and development of a new target; (2) the research of a combined medication mechanism and the innovative design of a clinical scheme; (3) development of new biomarkers; and the like.

T cell immunoglobulins and ITIM domain proteins (TIGIT, also known as WUCAM, Vstm3 or VSIG9) are checkpoint molecules that are expressed predominantly on the surface of immune cells such as NK cells, T cells, Treg cells, etc. Human TIGIT consists of an extracellular IgV-like domain, a type I transmembrane domain, and intracellular Immunoreceptor Tyrosine Inhibitory Motif (ITIM) and immunoreceptor tyrosine tail motif (ITT), which are typical inhibitory receptor proteins. TIGIT competes with the co-inhibitory receptor CD96, the co-stimulatory receptor CD226 (also known as DNAM-1) for binding to ligands CD155 (also known as PVR or necl-5) and CD112 (also known as nectin-2). CD155 is a high affinity core ligand for TIGIT, which interacts with TIGIT much higher than other partner molecules in the pathway. Structural biology studies have shown that molecular pairs such as CD155/TIGIT, CD155/CD226, CD155/CD96 interact through extracellular IgV-like domains in a conserved pattern called "Lock-Key" (Lock and Key); the interacting epitopes cover the entire spatial area between the "lock-key".

TIGIT is a novel immune checkpoint molecule, the regulatory mechanism of which is similar to PD-1/PD-L1. Under normal physiological conditions, negative immune regulation of CD155/TIGIT can be considered as another complement to MHC class I mechanisms to protect normal cells of epithelial origin (broadly expressing CD155) and the like from NK cells. However, this mechanism is also "stolen" by tumor cells to avoid the killing of the immune system and achieve immune escape. Early studies revealed high expression and tumor infiltration of TIGIT CD8+Correlation of T cell depletion and observed that TIGIT blocker reversed CD8 in a mouse tumor-bearing model+Good effects on T cell depletion and enhancement of antitumor activity; the TIGIT antibody and the PD-1/PD-L1 antibody are combined to show remarkable antitumor activity, and the synergy between the CD155/TIGIT and the PD-1/PD-L1 pathway is suggested. Meanwhile, in a large number of studies aiming at clinical patients, significant improvement of TIGIT expression level on the surfaces of T cells infiltrated by tumors and NK cells is also observed; the expression of CD155 in tumor tissues is also remarkably increased, and is closely related to the stage of TNM, the overall survival rate, the recurrence rate and the like.

With the progress of research, the action mechanism of TIGIT in the regulation of tumor immune negativity is gradually clarified, and can be summarized into three aspects: (1) TIGIT is highly expressed on the surfaces of NK cells and effector T cells related to tumor infiltration or migration, CD155 is highly expressed on the surface of the tumor cells, and the tumor cells directly act on the NK cells and the effector T cells through the combination of CD155/TIGIT to inhibit the activity of the NK cells and the effector T cells, so that the function of the NK cells and the effector T cells is exhausted; (2) treg cells in a tumor microenvironment inhibit inflammatory reaction by secreting anti-inflammatory factors such as IL-10 and the like; the tumor cells are combined with TIGIT with high expression on the surface of the Treg through CD155, the function of the Treg is promoted, and the inflammatory reaction of a tumor microenvironment is further inhibited; (3) the NK cell and the T effector cell surface TIGIT form a competitive competition for the combination of a co-stimulation receptor CD226(DNAM-1) and CD155 on the one hand, and inhibit the expression of the CD226 on the other hand, so that the function of the CD226 is lost, and the activity of immune effector cells is further inhibited. The reason why TIGIT has a clearly opposite regulatory function (suppression and promotion) on immune effector cells and Treg cells is not clear in the aforementioned (1) (2).

In addition, researches in a mouse model also show that the expression of TIGIT is closely related to NK cells, the T cell exhaustion is closely related to the NK cell exhaustion, and the therapeutic effects of the PD-1/PD-L1 antibody and the TIGIT antibody depend on the existence of the NK cells; the key role of NK cells in multiple immunosuppression and the great potential of TIGIT as an immunotherapy target are deeply revealed, and an important theoretical basis is provided for clinical combined use of immune checkpoint antibodies.

According to the gradually clear action mechanism of TIGIT, through an immunotherapy antibody targeting TIGIT, the immunosuppression signal mediated by a CD155/TIGIT channel is blocked, and NK cells and CD8 capable of reversing tumor infiltration+The exhaustion of T cells releases the tumor killing activity of immune effector cells, and good anti-tumor curative effect is expected to be obtained.

Collecting NK-92MI cells in logarithmic growth phase and adjusting cell density to 3 × 105And/test, combining the cells with an APC-labeled mouse anti-human TIGIT antibody (5 mu l/test) or a PD-1 antibody (5 mu l/test) for 1h on ice, setting 3 multiple wells in each group, setting no antibody as a blank control group, washing the cells for 2 times by using a DMEM medium (containing 10% FBS), detecting the cells by using a flow cytometer, and determining the TIGIT and PD-1 expression conditions on the surfaces of the NK-92MI cells according to the average fluorescence intensity.

2.4 cell killing experiments and evaluation of antibody function

Three tumor cells, namely A549, A431 and U251MG, are used as target cells, NK-92MI is used as effector cells, an in vitro killing experiment is carried out, and the functional activity of the antibody is evaluated according to the experiment.

The target cells in good state are 5X 103Cells/ml × 100 μ l/well are inoculated in 96-well plates and cultured for 24-48 h until they are full. AET2010 was diluted with DMEM medium (containing 10% fetal bovine serum): the initial concentration is 200 mug/ml, 6 gradients are serially diluted by 2 times of gradients, and the diluted solution is added into the corresponding position of a 96-well plate according to 50 mug/hole; the growth medium adjusts the effector cells with good state to a specific density, and the effector cells are added into the corresponding position of a 96-well plate according to 50 mul/well; the effective target (E: T) ratios used were 1:1(NK-92 MI: A549), 2: 1(NK-92 MI: A431) and 0.25:1(NK-92 MI: U251 MG); 3 duplicate wells were set for each experimental condition, and separate target cell control wells and effector cell control wells (also subjected to subsequent supernatant aspiration and wash steps, equivalent to a blank medium control) were set; an irrelevant human IgG1 antibody was used as an isotype control (negative), and MK7684 was used as a positive control, and diluted under the same conditions. Standing the cell culture box for 5-12h (A549 and A431 are 12h, and U251MG is 5h), sucking the supernatant, transferring the supernatant to a 96-hole deep-hole plate, centrifuging at 1500rpm for 15min, and taking the supernatant for quantitative detection of the levels of the killer cytokines such as perforin, TNF-alpha, IFN-gamma and the like. Detection methodThe corresponding ELISA detection kit was used.

The 96-well cell culture plate after the supernatant was aspirated was washed twice with PBS, the CCK8 reagent was diluted to a final concentration of 10% with DMEM medium (containing 10% fetal bovine serum) and added at 100 μ l/well, the cell culture chamber was left standing at 37 ℃ for 2.5 hours, absorbance at a wavelength of 450nm (595nm is a reference wavelength) was measured with a microplate reader, and the cell killing rate was calculated: the cell killing rate is [1- (absorbance of experiment group-absorbance of effector cell control group)/(absorbance of target cell control group-absorbance of blank medium) ] × 100%; concentration-kill curves were plotted and EC50 values were calculated.

For TIGIT and PD-1 double-positive target cells U251MG, a single anti-PD-1 antibody Nivolumab group and an equal ratio combined group respectively with AET2010 and MK7684 are further arranged on the basis of the above, the concentration of AET2010 is the same as that of AET2010, and the concentration of MK7684 is the same as that of AET 2010.

Second, result in

1. Flow assay of cell surface molecules

As shown in a in fig. 18, the cell surface CD155 positivity of target cells a549, a431 and U251MG was 99% or more; as shown in B in FIG. 18, the positive rate of PD-L1 on the cell surface of U251MG is more than 90%, while the positive rates of PD-L1 on the cell surfaces of A549 and A431 are lower. As shown in C and D in FIG. 18, the positive rates of two inhibitory receptors, TIGIT and PD-1, on the surface of NK-92MI of effector cells were 21.1% and 19.7%, respectively; it is thus presumed that the target cells have a certain inhibitory effect on the killing of NK-92MI, and that the addition of antibodies is blocked to promote and enhance the killing activity of NK-92MI, thereby evaluating the functional activity of the antibodies.

Effect of AET2010 on NK-92MI cell in vitro killing tumor cell Activity

As shown in FIGS. 19-21, compared with an unrelated human IgG1 antibody control (isotype control antibody), AET2010 and MK7684 can increase the levels of IFN-gamma of NK-92MI cells releasing perforin and TNF-alpha within a certain concentration range, and the difference has statistical significance.

As shown in FIG. 22, compared with isotype-independent control antibody, AET2010 and MK7684 can increase the killing rate of NK-92MI cells on tumor cells within a certain concentration range, and show a dose-dependent relationship. For A549 cells (A), the EC50 values corresponding to AET2010 and MK7684 were 30.70 μ g/ml and 27.43 μ g/ml, respectively; for A431 cells (B), the EC50 values for AET2010 and MK7684 were 24.93 μ g/ml and 24.25 μ g/ml, respectively; for U251MG cells (C), the EC50 values corresponding to AET2010 and MK7684 were 23.70 μ g/ml and 29.94 μ g/ml, respectively, and the promotion effects of the two on the in vitro tumor cell killing activity of NK-92MI cells were equivalent.

Meanwhile, for U251MG cells with double positive CD155 and PD-L1, the promotion effect of the combination of AET2010, MK7684 and Nivolumab on the killing activity of NK-92MI is also obviously stronger than that of the single use (figure C); the release levels of the corresponding killer cytokines were also significantly elevated (fig. 21).

At an antibody concentration of 100. mu.g/ml, the killing rate of the combination of AET2010 and Nivolumab on U251MG is 72.52 +/-0.05%, and the killing rate of the combination of MK7684 and Nivolumab on U251MG is 70.12 +/-2.60%; at an antibody concentration of 200. mu.g/ml, the killing rate of the combination of AET2010 and Nivolumab on U251MG was 71.56 + -0.10%, and the killing rate of the combination of MK7684 and Nivolumab on U251MG was 70.02 + -0.58%.

Example 7 evaluation of in vivo drug efficacy of AET2010

Materials and methods

1. Materials: BALB/c nude mice (male, 4 weeks old) were a product of Witongli, Inc., and other experimental materials were the same as in the previous examples.

2. The method comprises the following steps: 4-week-old Balb/c nude mice (N ═ 20) were inoculated subcutaneously in the back with A549 tumor cells (5X 10)6cells/100 μ l/cell), tumor growth was observed periodically, and tumor volume was measured (V ═ long diameter × short diameter)2/2). When the tumor grows to 300 +/-100 mm3At this time, groups were randomized into four groups of 5, 3 experimental groups and 1 control group. The groups were dosed as follows: AET2010 panel was injected with NK-92MI cells (1X 10) via tail vein adoptively7cells/200. mu.l/mouse) and AET2010 (300. mu.g/mouse), MK7684 panels were injected with NK-92MI cells (1X 10 cells) via tail vein7cells/200. mu.l/mouse) and MK7684 (300. mu.g/mouse), independent antibody panel was injected by tail vein adoptively with NK-92MI cells (1)×107cells/200. mu.l/mouse) and isotype-independent control antibody (human IgG1 antibody against IFN-. alpha.) (300. mu.g/mouse); the control group was injected with PBS buffer (200. mu.l/mouse) via tail vein. The frequency of treatment administration was once every 5 days. During the experiment, mice survival status was observed and recorded periodically weekly, tumor volumes were measured and recorded, and tumor growth (tumor volume-time) curves were plotted. Tumor volume in mice over 2000m on day 30 after initiation of treatment3Mice were euthanized, tumor masses were removed, weighed and photographed.

Second, result in

A CDX mouse model inoculated with A549 cells subcutaneously is taken as a research object, and the effect of the antibody on promoting the activity of NK-92MI in vivo and further killing tumors is evaluated by adoptively infusing NK-92MI cells and applying antibody drug therapy, so that the in vivo efficacy of the antibody is preliminarily determined by the model. In the experimental process, the tumor volume of the PBS control group of mice exceeds 2000mm on the 20 th day3Then the patient is sacrificed; mice were sacrificed at the experimental end-point (day 30 after treatment initiation) and tumors were weighed. The results are shown in fig. 23-24, where AET2010 and MK7684 had significant inhibition of tumor growth (P < 0.0001) compared to isotype control antibodies, and the antitumor effects of both were comparable.

AET2010 showed enhanced antitumor activity in a CDX mouse model with adoptive infusion of NK-92MI cells, whose potential pharmacodynamic characteristics were expected.
