Background technique
Breast cancer is common one of the malignant tumour of women, and disease incidence cumulative year after year has become Chinese women cancer
The first cause of associated death.On the basis of gene expression difference, the immunohistochemistry marker of selected characteristic (estrogen by
Body ER, progesterone receptor PR, human epidermal growth factor acceptor Her2), breast cancer is clinically divided into 4 seed types i.e.:
Luminal A (ER+/PR+Her2-)、Luminal B(ER+/PR+Her2+Or ER+/PR+Ki67 > 14%), Her2+(ER-PR-
Her2+) and three yin breast cancer (Triple-negative breast cancer, TNBC) (ER-PR-Her2-).Wherein, three
Negative patient with breast cancer accounts for about the 15%-20% of breast cancer, and is mainly in young women.Differentiation degree is low, growth is fast, tumour body
Product is the feature of TNBC greatly.Because of TNBC inside tumor, the heterogeneity between different tumours is big, still without effective targeted therapy
Method.Simultaneously as not expressing hormone receptor, endocrine therapy is not reacted.Current clinically drug therapy first choice chemotherapy,
Chemotherapeutics includes anthracycline, taxanes and/or platinum-like compounds.With patient with breast cancer, especially three negative breast cancer are suffered from
Person increases year by year, needs a kind of effective therapeutic strategy.
Different from traditional tumour therapeutic strategy, immunization therapy targets patients immune system, itself antitumor exempts to activate
Epidemic disease reaction.Programmed death receptor -1 (programmed death-1, PD-1) is expressed in T cell, belongs to immunoglobulin
Superfamily I type transmembrane glycoprotein.Through FDA approval listing two kinds targeting PD-1 blocking antibody (Pembrolizumab,
Nivolumab) the significant effect in melanoma treatment.However, targeting PD-1 Immunotherapy Strategy is in other solid tumors, such as cream
Offer limited effectiveness in gland cancer, liver cancer etc., and different degrees of immunization therapy occur and resist and recur.How immune control is improved
Curative effect is treated, one of current immunization therapy research hotspot is become.
Cell cycle dependent kinases 5 (cyclin-dependent kinase 5, CDK5) belong to CDK family, with it
Unlike his CDK: CDK5 not cell cycle regulation.Clinical data is also shown: kinds of tumor cells (breast cancer, it is non-small thin
Born of the same parents' lung cancer, thyroid cancer, nasopharyngeal carcinoma, gastric cancer etc.) in, CDK5 expression activation is positively correlated with malignancy of tumor progress, and and patient
It is negatively correlated that OS, PFS etc. treat terminal.Especially in May, 2017, Science report CDK5 inhibitor can significantly inhibit it is swollen
The expression of oncocyte PD-L1 has further been pushed to target CDK5 as the research of the antineoplastic new strategy of starting point.Currently,
There are several Cdk5 inhibitor to enter clinical experimental stage, such as the first and second generation ATP competitive inhibitor R-roscovitine,
Dinaciclib and AT7519 etc..And non ATP competitiveness CDK5 inhibitor such as Cpd1, p5 peptide etc. also has become antineoplastic new medicine source
Molecule.But there is no disclose being associated between CDK5 and the immunization therapy of tumour for the prior art.
Summary of the invention
In view of the foregoing deficiencies of prior art, the purpose of the present invention is to provide the connection that can be used for immunotherapy of tumors
Combination with medication combination.
First aspect present invention provides a kind of combination medicine combination for immunotherapy of tumors, including a effective amount of
CDK5 inhibitor and a effective amount of immunologic test point blocking antibody.
The present invention provides CDK5 inhibitor in the pharmaceutical composition of preparation and immunologic test point blocking antibody drug combination
Purposes.
The CDK5 inhibitor refers to the compound for having inhibitory effect for CDK5 kinase activity.
Include but is not limited to inhibitory effect for CDK5: inhibiting CDK5 kinase activity, or CDK5 gene is inhibited to turn
Record or expression.
The CDK5 inhibitor can be siRNA, shRNA, antibody, small molecule compound, small peptide.
What the embodiment of the present invention was enumerated, the CDK5 inhibitor is R-Roscovitine, and the CDK5 inhibitor is also optional
From: olomoucine (olomoucine) and its derivative, Dinaciclib (MK-7965, SCH727965), AT7519, CIP,
P5, Cpd1 etc..
The immunologic test point blocking antibody can be selected from one of anti-PD-1 antibody, anti-PD-L1 antibody, anti-CTLA-4 antibody etc.
Or combinations thereof.In the preferred embodiment of the invention, the immunologic test point blocking antibody therapy medicine is anti-PD-1 antibody.
The combination therapy pharmaceutical composition can be any one in following form:
1) independent preparation is respectively prepared in CDK5 inhibitor and immunologic test point blocking antibody, the dosage form of preparation can be identical
Or it is different, administration route may be the same or different.
2) CDK5 inhibitor and immunologic test point blocking antibody are configured to compound preparation.In CDK5 inhibitor and immune inspection
Blocking antibody is made an inventory of using the administration of identical administration route and when applying simultaneously, the shape that the two is configured to compound preparation can be used
Formula.
Second aspect of the present invention provides a kind of immunotherapy of tumors drug combination treatment method, to apply to Object associates
A effective amount of CDK5 inhibitor and a effective amount of immunologic test point blocking antibody.
The object is mammal or the T cell of the mammal, macrophage, tumour cell.The lactation
Animal is preferably rodent, artiodactylous animals, Perissodactyla animal, Lagomorph, primate etc..The Primates
Animal is preferably monkey, ape or homo sapiens.
The object can be the patient for suffering from tumour or expect to improve the individual of anti-tumor immunity, or swollen to suffer from
The patient of tumor or the individual in vitro CTL cell for expecting to improve anti-tumor immunity.
It is can synchronizing or sequentially give a effective amount of CDK5 inhibitor and a effective amount of immunologic test point blocking antibody.
Based on CDK5 be newfound immunotherapy of tumors target spot, the present invention it has been investigated that, with immunologic test point hinder
Break in antibody combined medication, the two can play synergy, further enhance the inhibition for tumour.
The tumour that the immunotherapy of tumors is directed to includes the various hypotypes of breast cancer, including but not limited to: Luminal A
(ER+/PR+ Her2-)、Luminal B(ER+/PR+Her2+Or ER+/PR+Ki67 > 14%), Her2+(ER-PR-Her2+), with
