Definitions
- the present invention relates to the treatment of cancer, and especially to the treatment of head or neck squamous cell carcinoma (SCC) .
- SCC head or neck squamous cell carcinoma
- SCC Head and neck squamous cell carcinoma
- MAbs monoclonal antibodies
- K ⁇ hler and Milstein have found application in every aspect of biomedical research. They are currently used as probes into the fine structure of cellular components, in histocompatibility tests, radioimmunoassays, molecule purification procedures, immunohistochemistry, flow cytometry and electron microscopy.
- MAbs have provided new approaches to many problems in oncology.
- tumours In addition to improving the detection and localisation of tumours in vivo either through sensitive serum assays or through radioimmunoscintigraphy, they have improved the grading, staging and classification of haemopoietic malignancies and may provide significant prognostic information in a variety of tumours.
- MAbs have been suggested for use in novel therapeutic approaches, using their potential ability to target tumour cells. The use of MAbs unmodified or as vectors for radioisotopes, cytotoxic agents, enzymes or toxins to selectively target and kill tumour cells is the subject of much current research.
- One aspect of the invention provides a method of treating a cancer in a mammal, comprising administering a preparation carrying a cytotoxic level of radioactive atoms, the preparation being specific for the cancer cells, and in conjunction externally administering a cytotoxic dose of radiation to the cancer.
- a second aspect of the invention provides the use of a preparation specific for cancer cells and carrying a cytotoxic level of radioactive atoms in the manufacture of a medicament for the treatment of cancer of a mammal in conjunction with an externally administered cytotoxic dose of radiation.
- the cancer is preferably squamous cell carcinoma of the head or neck. It may, however, be of any solid tumour, for example cancer of the cervix, bladder, bowel, rectum or bronchus.
- the preparation is preferably a preparation of antibodies but may be any compound specific for the cancer cells, for example a ligand specific for a cell-surface receptor preferentially expressed by cancer cells.
- antibody we mean any molecule which retains a useful level of the cancer specificity of a cancer-specific immunoglobulin compound and of which the specificity-conferring region or regions is or are at least 50% homologous (preferably at least 80%, 90%, 95% or 99% homologous) to the most similar specificity-conferring region or regions of the said immunoglobulin.
- the antibody preparation may be a polyclonal collection of antibodies of restricted specificity.
- the antibody is a monoclonal antibody, an F ab ' , (F ab ) 2.
- immunoglobulins may be prepared by conventional methods for preparing monoclonal antibodies (see Monoclonal Hybridoma Antibodies Ed. J.G.R. Hurrell, CRC Press 1982, incorporated herein by reference) using cancer-associated antigens, for example epidermal growth factor receptors and polymorphic epithelial mucins.
- tumourrmucosa ratio of at least 4:1, preferably at least 5:1 or 10:1 is desirable.
- Non-antibody targeting means include epidermal growth factor and homologues and fragments thereof (for cancers such as squamous cell carcinoma of the head or neck which express high levels of the EGF receptor) , urokinase-type plasminogen activator and receptor-binding portions thereof, melanocyte-stimulating hormone and fragments thereof, etc.
- the cytotoxic radioactive atom may, for example, be iodine- 131, iodine-123, iodine-125, rhenium-186, rhenium-188 or yttrium-90.
- Such atoms may be attached to the cancer- specific compound by conventional techniques, for example via a cysteine residue (iodine or rhenium) or lysine residue (yttrium) or using the IODOGEN method (Fraker, P.J. et al (1978) Biochem . Biophys . Res . Commun . 80, 49-57).
- IODOGEN method Frraker, P.J. et al (1978) Biochem . Biophys . Res . Commun . 80, 49-57.
- Other methods are described in detail in "Monoclonal Antibodies in Immunoscintigraphy", J-F Chatal (CRC Press 1989) .
- sufficient radioactive atom is administered for a radiation dose of at least 500 cGy to be delivered to the tumour, more preferably at least 1000 cGy or at least 1500 cGy.
- a dose of more than 3000 cGy may be undesirably toxic or difficult to administer, and a maximum of 2000 cGy is preferred.
- the cancer-specific preparation is made up conventionally, typically in pyrogen-free, sterile, saline, typically for intravenous injection, as is known.
- administering in conjunction with we mean that the radioimmunotherapy and the externally applied radiation are administered sufficiently closely in time for the beneficial effect on the tumours to be greater than if the two forms of treatment are applied with a gap of 3 weeks between them.
- the administration of the cancer-specific preparation takes place during the administration of the externally applied radiation.
- the radioactive cancer-specific preparation is administered on about day 10-20, preferably at about day 15.
- the cancer-specific preparation can be administered up to about 2 weeks before external irradiation begins or up to about 2 weeks after external irradiation finishes.
- the external radiation may be delivered in a conventional way, for example using a linear accelerator, to deliver a dose of about 1000-7000 cGy, preferably about 5000 cGy, over a 1-10 week period, preferably about 4-6 weeks, in daily (Monday-Friday) doses.
- the patient has already undergone surgery to remove most of the tumour, and the methods and compositions of the invention are used to further improve the chances of success.
- the amount of tumour present at the time of treatment does not exceed 100 g, more preferably it does not exceed 20 g, more preferably still it does not exceed 10 g and ideally it does not exceed 5 g.
- it is less than 5 cm in diameter, more preferably less than 2 cm in diameter and ideally less than 1 cm in diameter. If the tumour is detected when it is so small, as can be the case with cancer of the cervix then the methods of the invention may be usefully employed without the necessity of surgical intervention.
- the first objective is to choose a suitable MAb against a SCC antigen for in vivo use.
- Immunohistochemistry may be performed on snap-frozen and paraffin-embedded tumour samples with a panel of MAbs against SCC antigens.
- Tumour xenografts may be established in nude athymic mice using SCC cell lines and the kinetics of the MAbs assessed.
- Immunohistology is performed on the xenografts, and macro- and icro-biodistribution studied.
- MAb and a second layer rabbit antimouse immunoglobulin is used.
- the reaction is developed with 3,3-diaminobenzidine tetrachloride (DAB) substrate. Suitable controls are used.
- DAB 3,3-diaminobenzidine tetrachloride
- SCC cell lines are cultured at 37°C in a humidified atmosphere of 5% C0 2 either in RPMI-1640 + 10% FCS or in
- Tumours are established by subcutaneous injection of 5 x 10 6 cells in 100 ⁇ l tissue culture medium in the right flank of female athymic nude mice.
- Antibodies are labelled with 123 I, 131 I or 125 I using the iodogen technique.
- the radiolabelled antibody is purified by gel filtration on a 20 ml Sephadex G-50 column previously treated with HSA.
- a 200 mCi dose of 131 I-labelled anti-(CA larynx) MAb ie a MAb against a carcinoma of the larynx or tongue
- a tumour uptake of about 0.0002 mCi of 13I I per gram of tumour is used, to give a tumour uptake of about 0.0002 mCi of 13I I per gram of tumour.
- the total dose to the tumour is about 60 Gy, with a whole body radiation dose (WBRD) of about 15 Gy.
- WBRD whole body radiation dose
- the required additional 20 Gy is supplied by external beam radiation.
- the antibody is conjugated to the chelating agent DTPA, using the bicyclic anhydride method 6 .
- Free DTPA is separated from DTPA-MAb by Sephadex G-50 gel-filtration using 0.1 M sodium acetate as elution buffer. Ill In citrate is added to the DTPA conjugate and allowed to react for 15- 30 mins. Purification is as for the iodinated MAb.
- Yttrium-90 Yttrium-90 in 0.04 M hydrochloric acid is complexed using 0.5 sodium acetate.
- DTPA-conjugated antibody is added to the complex. After 1-2 h incubation, EDTA is added to react with free ⁇ Y. Separation is as for iodinated MAb. 5.
- the MAbs are administered intravenously to unanaesthetised mice. Dual labelling experiments may be performed using 131 I and 125 I to compare antibody kinetics in the same animal. At fixed intervals after injection, groups of mice are sacrificed and tumour, normal tissue and blood obtained, weighed and the radioactivity counted in a ⁇ -counter, along with serially diluted standards of injectate. Results may be expressed as percentage of injected dose per gram of wet tissue (%i.d./g) and as tumour to normal tissue ratios. The specificity index (S.I.) for a tissue may be calculated. The higher the S.I. of a tissue the more specific the antibody is for the tumour than that tissue. 6. Autoradiography
- Gross autoradiography is performed by placing histological slides in direct contact with autoradiographic film. Exposure time is 8 days at 4°C. Exposed films are developed for 5 min, fixed and dried. For micro- autoradiography, sections are placed on gelatin coated slides, dried at 37°C overnight, hydrated and dipped in Ilford K5 emulsion (1:1 dilution). Exposure time is 3 weeks at 4°C in light-proof boxes. Developing time is 3-5 min.
- MAbs are radiolabelled and injected intravenously prior to surgery. Radioimmunoscintigraphy is carried out including anterior, posterior and spot views 7 . Tumour and normal tissue samples are obtained at surgery. Biodistribution studies are carried out as described above. Blood and urine samples are serially obtained and aliquots counted in the ⁇ -counter, along with standard injectate dilutions. Following centrifugation, radioactivity is measured in the plasma and the cell pellet.
- the final stage is to administer a MAb selected from the biodistribution and imaging studies as a radiation delivery vehicle in patients with head and neck carcinoma, in conjunction with externally applied radiation.
- a dose of 5000 cGy is applied as 25 daily (Monday-Friday) doses of 200 cGy over 5 weeks and 2000 cGy of radioactive antibody is administered as a single i.v. dose on day 15.
