Abstract
A bifunctional antibody has affinity for a target site and affinity for an organic molecule covalently linked to a cytotoxic agent or an enzyme capable of converting a prodrug into its cytotoxic form. The antibody may be used in therapy or diagnosis, especially in the treatment of tumours.
Description
Invention field
The present invention relates to bifunctional antibody and the application in the targeting anti-tumour agents in vivo thereof.
Background of invention
Therapeutical agent is well-known to the internal guide of privileged site.Particularly, wish very much to tumor locus guiding carcinostatic agent, improving the concentration of this position medicament, thereby improve its in and usefulness in the tumour.The example of the medicament of guiding tumour is well-known, and the specificity of wherein many dependence monoclonal antibodies is carried diagnostic reagent or therapeutical agent to target site.A kind of method is to use the radionuclide-antibody coupling matter that is positioned in the target tissue, and radionuclide can be brought into play its cytotoxicity in target tissue.
Yet find out, use radionuclide-antibody coupling matter to exist problem, for example, because the high molecular of conjugate makes conjugate relatively poor to the infiltration of target site.In addition, for make this conjugate in treatment effectively, must give the regular hour to be positioned target site.Therefore there is the long time in vivo in radionuclide, and this causes the undesirable toxicity in non-target site.
Therefore wish not rely on radiolabeled cytotoxic agent and administration of antibodies, thereby before using radiolabeled cytotoxic agent, make antibody be positioned target site.
US-A-5630996 has described a kind of method of using the vitamin H of antibody-Streptavidin conjugate guiding radioisotope labeling.Streptavidin has the high-affinity to vitamin H, and can make radionuclide be positioned target site by vitamin H-Streptavidin interaction.But Streptavidin is a kind of immunogenic protein that has in human body, therefore may be unsuitable for the multiple long-term treatment and use.
US-A-5591828 discloses the bi-specific antibody that has the avidity of metallo-chelate and specified protein epi-position.Yet, inner complex EDTA-Y
90And DTPA-Y
90Preferably need covalency add can with the fos-peptide of jun-peptide interaction on the antibody, with enough Y
90Be positioned target site.In addition, at sequestrant (EDTA) and radionuclide (Y
90) between may dissociate.Therefore, perhaps be not effectively in the location of tumor locus, and the method for generation fos-peptide-metal-chelating conjugate is tediously long, and is unsuitable for scale operation.
Summary of the invention
The present invention relates to the antigen that exists in the tumor locus and therapeutical agent or diagnostic reagent are all had the bifunctional antibody of avidity, wherein this medicament be a kind of radiolabeled or with the covalently bound organic molecule of cytotoxic agent.In an independent embodiment, this organic molecule combines with a kind of enzyme that prodrug can be converted into the cell toxicant form.
Therefore the invention provides a kind of by using the localized method of bifunctional antibody and organic molecule enhancing therapeutical agent in proper order at target site.The present invention can be used for treatment or diagnostic uses.
Generally speaking, this organic molecule is the good infiltration at vitamin H or a kind of display target position, otherwise bio distribution in vivo is the neutral organic molecule.
An advantage of the invention is and can use a kind of cytotoxic agent, the target position that it will be positioned to wish owing to interacting with antibody, but the toxicity of non-target tissue is reduced, because unconjugated medicament will be removed in body effectively.
In one embodiment, cytotoxic agent is a kind of radionuclide, and covalently bound with organic molecule, perhaps itself is the part of organic molecule.Can select radionuclide performance therapeutic action, for example as a kind of antineoplastic agent, or can be diagnostic purpose and use, as tumor imaging.
In another embodiment, this organic molecule is connected with a kind of enzyme that can be used for suitable prodrug is converted into active cells poison form.
Invention is described
Antibody of the present invention can produce with routine techniques, and for example hybridoma is synthetic, recombinant DNA technology or phage display.These antibody can derive from any kind, comprise rodent, but preferably antibody sources is in the Mammals except that rodent, and for example sheep, goat or cow are to produce high-affinity antibody.
These antibody generally have at least 10 to part separately
10L/mol, preferably 10
11L/mol, more preferably 10
12L/mol, most preferably 10
13The avidity of l/mol.
According to bifunctional antibody of the present invention can be complete antibody, perhaps can be its fragment, as f (a/b)
2In another embodiment, antibody can contain two strand fv fragments.The preparation of difunctional sFv is well-known.For example, people such as Carter, modern biotechnology viewpoint (Current Opinion in Biotechnology) 1997,8: 449-454 disclose to utilize and have bitten mattress body display library and produce difunctional sFv.
In addition, also can utilize the recombinant DNA technology modified antibodies, with " humanization " these antibody, making it has lower immunogenicity when the patient is used.Humanized antibody should comprise to come from least to be had the monoclonal antibody of avidity and organic molecule is had the hypervariable region of the monoclonal antibody of avidity target antigen.Remaining antibody variable region can be the variable region of human normal immunoglobulin.At complete antibody or fragment such as F (ab ')
2In can have the human normal immunoglobulin of higher proportion.When using strand Fv fragment, this fragment can contain aforesaid hypervariable region, and randomly is derived from the variable framework of human normal immunoglobulin.
Antibody can have the avidity to the particular target position.Usually, target site is a kind of tumour, and antibody has the avidity to tumor associated antigen.An example of tumor associated antigen is the carcinomebryonic antigen of finding in colorectal carcinoma and other gland cancer (CEA).
In preferred embodiments, antibody has ligand affinity to radiolabeled organic molecule.The present invention includes in the independent covalent attachment of radionuclide and organic molecule and the organic molecule itself the suitably simple radio-labeling of atom.For example, organic molecule can comprise radiolabeled phosphorus or iodine atom and become a kind of cytotoxicity organic molecule.Using of this molecule will make radionuclide by being positioned tumor locus with antibodies, to tumour performance cytotoxicity.Radionuclide with cytotoxicity is well-known.A kind of preferred radionuclide that can use in the present invention is the radio isotope of iodine, as can be used for the I of diagnostic uses
123, I
124And I
125And the I that can be used for treating
131Can be used for the preferred radionuclide of another kind of the present invention is P
