Definitions

  • the present invention relates to antibody-dye conjugates which are suitable for binding to structures of newly formed vessels and their use for the intraoperative presentation of pathological angiogenesis.
  • angiogenesis takes place in response to certain signals.
  • Angiogenesis is a process that takes place preferentially in the marginal area of a disease center. Factors are released from the center of the disease center, which diffuse to the edge region of the disease center. These factors are also known as angiogenesis stimulators. If these angiogenesis stimulators reach the healthy tissue in the edge area of a focus of the disease, they have so far not been included in the focus of the disease
  • the vessels growing out of these vascular buds form a new capillary network in the edge area of the focus of the disease. This process can always ensure an adequate supply of nutrients for the focus of the disease. It has been found to be particularly important that the growth of tumors and their metastases depends on the ability to induce angiogenesis.
  • Surgical therapy is now a standard measure for the treatment of localized areas of disease. It has gained great importance in tumor treatment. However, it has been found that, despite improved surgical techniques, the number of local recurrences is considerable, since the anatomical conditions in the human organism only rarely allow the foci of the disease to be removed over a large area. In many Organs (e.g. in the brain) must not be removed on a large scale in order to maintain healthy tissue. The risk of injury to healthy organs increases with the radical nature of the surgical procedure.
  • treatment If treatment is accurate, it would allow the focus of the disease to be completely removed and the healthy tissue to be largely protected.
  • Dyes for imaging disease sources are already known (Poon WS et al., J Neurosurgery (1992) 76: 679-686, Haglund MM et al., Neurosurgery (1996) 38: 308-317). They are preferably taken up directly by tumor cells or accumulate non-specifically in the extracellular space of the tumors. Since the mechanism of accumulation can also be demonstrated in healthy tissue, the specificity and sensitivity of the substances used is low.
  • Angiogenesis takes place preferentially in the marginal area of disease centers. By showing the angiogenesis, the border to healthy tissue can be shown.
  • Antibodies for the detection of angiogenesis in the focus of disease are already known and are used for the display of newly formed vessels in the histological tissue section, for the detection of various proteins in the focus of the disease or as carrier molecules for therapeutic substances.
  • antibodies in combination with dyes so-called antibody-dye conjugates, are not known, which can be used for the intraoperative delimitation of the focus of the disease by selective display of the edge region of a focus of the disease.
  • the object of the present invention is therefore to provide antibody-dye conjugates for intraoperative tumor border imaging.
  • the antibodies of the antibody-dye conjugates according to the invention are directed against structures which are specific for the process of angiogenesis.
  • the antibody-dye conjugates according to the invention comprise dyes which, because of their enrichment, enable them to be displayed optically.
  • the antibody-dye conjugates according to the invention are thus suitable for representing the boundary of a focus of disease, the so-called edge area, with healthy tissue by intraoperative, optical diagnostics. This makes it possible to completely remove the focus of the disease while largely protecting the healthy tissue.
  • Antibodies are known which are directed against molecules which are strongly expressed in the angiogenetically active tissue and are only expressed at a very low level in the adjacent tissue (WO 96/01653).
  • antibodies that are directed against the receptors for vascular growth factors, receptors on endothelial cells to which inflammatory mediators bind, receptors on endothelial cells to which matrix molecules bind, and matrix proteins that are specifically expressed in the formation of new vessels (Brekken et al., Cancer Res. (1998) 58: 1952-9 and Schold SC Jr et al., Invest. Radiol. (1993) 28: 488-96).
  • EDB fibronectin also known as oncofetal fibronectin, is a splice variant of fibronectin, that specifically forms around newly formed vessels in the process of angiogenesis.
  • the focus of the disease does not lead to new formation of EDB fibronectin in healthy tissue. This maintains specificity during the surgical procedure.
  • Antibodies against growth factor receptors or inflammation mediators on the endothelial cell, which are also specifically expressed in the tumor border area, can also be regenerated during the surgical procedure in healthy tissue near the focus of the disease.
  • Antibodies L19 and E8 against EDB fibronectin are particularly preferred in the inventive antibody-dye conjugate.
  • Such antibody-dye conjugates are also the subject of the present invention.
  • the known antibodies are conjugated with dyes, the accumulation of which in the tissue can be optically detected and which enables the intraoperative delimitation of the peripheral area of a disease center.
  • the advantage of the antibody-dye conjugates according to the invention is that they can be used for a selective fluorescence staining of tissues in the neoangiogenic stage.
  • the fluorescence staining is tumor-specific and provides a fluorescence signal that can be detected in a high signal-to-background ratio.
  • Antibody-dye conjugates for fluorescence imaging for the purpose of percutaneous, non-invasive tumor imaging are also known (Neri D et al., Nature Biotechnology (1997) 15: 1271-1275).
  • antibody-dye conjugates are not known which preferentially accumulate in the edge region of a focus of disease.
  • Protein-dye conjugates for intraoperative tumor imaging are also known.
  • a disadvantage of these conjugates is that in particular hypoxic and metabolically undersupplied tumor cells absorb the conjugates.
  • the tissue in the marginal area of tumors is well vascularized and the cells are adequately supplied with oxygen and nutrients, the known protein-dye conjugates are not sufficiently enriched.
  • the antibody-dye conjugates according to the invention are largely independent of the metabolic state of the focus of the disease.
  • the optical detection of the limits of a disease focus can be carried out in different ways, the detection of the dye-specific fluorescence radiation induced by appropriate excitation light is generally preferred. Depending on the emission wavelength, the fluorescence can be recorded directly macroscopically or microscopically and, if necessary, simultaneously digitally recorded by imaging detection systems and displayed on a screen.
  • Fluorescence radiation of the spectral range 400 to 650 nm can be detected visually.
  • a wavelength of 450 to 600 nm is particularly preferred.
  • the particular advantage of using the visible range of light is that the detection of fluorescence is possible with little technical effort.
  • Excitation light which is generated by suitable lasers or laser diodes, is coupled into a light guide and guided to the area to be diagnosed via this light guide.
  • the introperative tumor edge detection is carried out by large-scale irradiation of the area.
  • the reflected excitation light is blocked by a filter (e.g. filter glasses worn by the examining person) and only the dye-specific fluorescence is observed (macroscopic observation).
  • the fluorescence can be recorded using an operating microscope (microscopic observation). Due to the low penetration depth of VIS light in
  • Tissues (a few millimeters) can be superficially localized in this way
  • New vessel formation can be detected.
  • Another advantage of the spectral range of visible light is the low penetration depth into the tissue and emission from the tissue. In this way, the detectable signal is not falsified by signals from deeper tissue parts and can be assigned precisely to the superficially visible tissue structures.
  • the present invention thus also relates to antibody-dye conjugates whose dyes induce an optical signal in the visible spectral range of the light.
  • the use of antibody-dye conjugates with dyes that absorb in the spectral range of the near infrared light (NIR; 600 - 900 nm) enables the detection of neovascularization in deeper tissue layers (up to 1 cm), since NIR is not weakly absorbed by tissue and therefore has a greater depth of tissue penetration.
  • the observation of the fluorescence is not possible visually and can be done by CCD cameras (Charge coupled device camera), which are placed over the tissue area of interest. Both macroscopic and microscopic detection is possible.
  • CCD cameras Charge coupled device camera
  • those dyes are suitable for the antibody-dye conjugates which have an absorption maximum within the spectral range from 400 to 800 nm and at least one fluorescence maximum within 500 to 900 nm.
  • the present invention also relates to antibody-dye conjugates which are characterized in that the dye is only using a defined wavelength range of visible or near-infrared light induces a fluorescence signal.
  • Antibody-dye conjugates comprising dyes with visually detectable fluorescence are, for example, those from the following classes:
  • 4,4-difluoro-4-bora-3a, 4a-diaza-indacene such as e.g. B. Bodipy FL, Bodipy 493/503 or Bodipy 530/550 and derivatives thereof (US 4,774,339, US 5,187,288, US 5,248,782, US 5,433,896, US 5,451, 663), cyanine dyes, especially carbocyanines and merocyanines,
  • Coumarin dyes such as e.g. B. 7-amino-4-methylcoumarin, metal complexes of DTPA or tetraaza macrocycles (cyclen, pyclen) with terbium or europium or tetrapyrrole dyes, in particular porphyrins.
  • Antibody-dye conjugates comprising near-infrared dyes are, for example, those from the following classes:
  • Polymethine dyes such as dicarbocyanine, tricarbocyanine, merocyanine and
  • Rhodamine dyes phenoxazine or phenothiazine dyes
  • Tetrapyrrole dyes especially benzoporphyrins, chorines and
  • Preferred near infrared dyes in the antibody-dye conjugates are:
  • dyes in the antibody-dye conjugates from the above-mentioned classes which have one or more carboxyl groups which recede chemical activation can be coupled to amino groups of antibodies or antibody fragments.
  • Derivatives which contain maleimido or bromoalkyl radicals are also preferred, so that covalent coupling to the sulfhydryl group of the amino acid cysteine takes place.
  • dyes are preferred which have isothiocyanate groups which also react with amino groups.
  • the dyes in the antibody-dye conjugates must have high photostability and must not fade when exposed to light (photobleaching) in order to ensure a constant signal within the investigation period.
  • the present invention thus relates to antibody-dye conjugates which accumulate preferentially in the edge region of the cell tissue of a focus of disease and thus make the edge region of the focus of the disease optically representable.
