Definitions
- the currently used technique involves a monoclonal antibody or a cocktail of antibodies against tumor surface proteins with which the isolated bone marrow is incubated.
- Monodisperse polystyrene microspheres 4.5 um in size, with covalently attached sheep anti-mouse IgG (e.g., Dynal M450, Dynal Inc., Great Neck, NY) are then added to the mixture in order to bind to the tumor cell-attracted monoclonal antibodies (MoAbs) (rosette formation).
- the magnetic cells are removed by strong magnets and the clean bone marrow is re-injected into the patient.
- the effectiveness of ABMT procedures depends upon several factors including the type of beads used, how the beads are coated, and the nature of the antibodies used to coat the beads.
- the antibodies used it is advantageous to have antibodies which bind only to the target cells and do not remove desirable cells. Also, the binding to the target cells must be of a nature that a high proportion of these target cells are removed.
- the antibodies and mixtures of antibodies which have been used to coat magnetic microspheres used in bone marrow purging systems have had moderate success. Lack of selectivity and low rates of removal of target cells have limited the effectiveness of these procedures.
- the subject invention concerns a novel monoclonal antibody (MoAb), the cell line used to produce this MoAb, and magnetic microspheres coated with the novel MoAb.
- MoAb monoclonal antibody
- the MoAb of the subject invention recognizes the common acute lymphocytic leukemia (ALL) antigen (CALLA, CD10, BgplOO).
- ALL common acute lymphocytic leukemia
- This novel antibody is a high affinity murine IgGl, kappa (IgGlk) antibody which can be used in the diagnosis and identification of childhood leukemia.
- the novel antibody which has been designated WCMH15.14, can also be used in the therapy of childhood leukemia.
- the therapy involves immunomagnetic purging of residual leukemic cells in preparation for autologous bone marrow transplantation in children with acute lymphocytic leukemia.
- the monoclonal antibody may also find therapeutic application in hybrid toxin systems where the MoAb is coupled with a toxin such as diphtheria or reicin. These systems selectively seek out and destroy the target cancer cells.
- the monoclonal antibody of the subject invention is a murine IgGlk antibody produced from the fusion of mouse spleen oocytes immunized with the Nalm-6 cell line and fused to the NS1 myeloma cell line. Successful hybrids were selected in HAT median and cloned by limiting dilution on thymocyte feeder layers.
- the fusion which ultimately produced the MoAb possessing the advantageous features described here resulted in approximately 2000 successful hybrids.
- the production of hybrids is a very random event; no two hybrids are alike, and it is impossible to predict or control all the relevant characteristics of the resulting hybrids.
- the 2000 successful hybrids resulting from this fusion only 80 were found to produce antibody which bound to Nalm-6. Of those 80 hybrids producing the desired antibody, less than half were found to have the desired selectivity. That is, 37 of the hybrids produced an antibody which bound to Nalm-6 but not Jurkat cells. Even in the unlikely event that a cell line produces the desired antibody and has the necessary selectivity, the cell line may be of no value if it is not stable.
- the subject culture deposit will be stored and made available to the public in accord with the provisions of the Budapest Treaty for the Deposit of Microorganisms, i.e., it will be stored with all the care necessary to keep it viable and uncontaminated for a period of at least five years after the most recent request for the furnishing of a sample of the deposits, and in any case, for a period of at least 30 (thirty) years after the date of deposit or for the enforceable life of any patent which may issue disclosing the culture.
- the depositor acknowledges the duty to replace the deposit should the depository be unable to furnish a sample when requested, due to the condition of the deposit. All restrictions on the availability to the public of the subject culture deposit will be irrevocably removed upon the granting of a patent disclosing it.
- the monoclonal antibody produced by the deposited cell line has several uses in the detection and therapy of children with acute lymphocyte leukemia.
- the antibody can be used in standard immunoassay procedures in order to detect the presence of leukemia antigens in a biological sample suspected of containing evidence of the disease.
- WCMH15.14 MoAb can be used in the treatment of leukemia patients is the coating of magnetic microbeads which are to be used in the purging of bone marrow from these patients.
- the characteristics of a monoclonal antibody that would be most useful for clinical use in purging marrow of residual leukemic cells prior to autologous marrow transplants for children with acute lymphoblastic leukemia would include: (1) the ability of the antibody to bind to the leukemic cells in a high percentage of patients, (2) the ability of the antibody to efficiently purge leukemic cells from marrow when used with magnetic microspheres in the immunomagnetic purging procedure, and (3) the antibody should not bind to stem cells which are needed to reconstitute normal marrow function after transplantation.
- the monoclonal antibody of the subject invention binds target cells selectively, and with a high degree of affinity, WCMH15.14, or immunological equivalents, can be used alone or in combination with a cocktail of other MoAbs to increase the efficiency of the bone marrow purging system.
- microspheres can be used to coat the beads using standard procedures well known to those skilled in the art. See, for example, Treleaven et al. (1984), supra: Kemshead et al. (1986), supra: Kvalheim, G., O. Fodstad, A. Pihl, K.
- Another procedure which utilizes the novel monoclonal antibody of the subject invention in the therapy of leukemia patients is the selective destruction of target cells with appropriate toxins.
- This technique involves the coupling of the novel MoAbs to a toxin so that the toxin is specifically delivered to the target cells.
- This procedure can be used in vivo and the antibody coupled to a number of different toxins, including poisonous lectins, ricin, abrin, modeccin, botulina, and diphtheria toxin.
- the construction of such a hybrid toxin could proceed, for example, according to the disclosures of United States Patent Nos. 4,675,382
- the cells were plated out into four 96-well flat bottom plates with approximately 200 microliters per well. The plating was done with a 10 cc pipette to minimize shearing forces of the newly formed hybrids. The four plates were then incubated at 37°C with 5% C0 2 in air for 10 days, at which time vigorous growth in each well was apparent and beginning to exhaust the nutrient supply.
- the cells were washed 3 times with cold PBS, reacted with a goat anti-mouse peroxidase conjugated antibody for 30 minutes, washed twice again, and the peroxidase substrates o-phenylenediamine and hydrogen peroxide were added.
- the brown color indicating a positive reaction identified the wells containing monoclonal antibody binding to the particular cell.
- the results of this screen indicated that 80 wells contained antibody reacted with Nalm-6 cells (20% of the 400 wells) and that 37 wells contained antibody that bound to Nalm-6 cells but not to Jurkat cells.
- the remainder of the clones are stable and underwent extensive characterization with a variety of immunoassays, as well as immunoprecipitation experiments involving 1-125 surface labeled Nalm-6 cells.
- One antibody, WCMH15.14 precipitated a 100 kilodalton surface glycoprotein, blocked the biotinylated CA LA antibody, and exhibited the characteristic cell binding distribution of other CD10 antibodies.
- the other 11 stable clones do not bind the common ALL antigen.
- the antibodies were isotyped using the Zymed mouse isotyping kit.
- WCMH15.14 was found to be a murine IgGl, kappa monoclonal antibody.
- Purging experiments were conducted where magnetic microbeads were coated with a variety of monoclonal antibodies to test the ability of these antibody-coated beads to bind to the target cells and to assess the selectivity and range of the binding.
- Cells from the Na_m-6 pre-B cell line were used as representative leukemia cells. 1 x 10 6 cells per well were placed in a 96-well microtiter plate and cooled to 4°C. One hundred ml of a 1:200 dilution of the selected monoclonal antibody in phosphate buffered saline (PBS) was incubated at 4°C for 30 minutes. The cells were then washed 3 times with PBS and transferred in cold PBS to a 12x75 mm plastic tube containing 4 ml of PBS.
- PBS phosphate buffered saline
- WCMH15.14 can be expected to have a high probability of effectively removing leukemic cells for a broad range of patients suffering from childhood leukemia.
- the ability to bind with leukemia cells from a high percentage of the patients tested also has important implications in terms of the antibody's use as a diagnostic tool. Because it recognizes a broad range of leukemic cells, WCMH15.14 would be less likely to give false negatives when used to detect the presence of leukemic cells in a biological sample.
- Example 2 Use of WCMH15.14 in Cocktail with Other Monoclonal Antibodies
- monoclonal antibodies that recognize malignant and normal pre-B cells have been shown to be useful in a cocktail along with WCMH15.14 to purge leukemic bone marrow.
- These antibodies include DU- A L-1, a CD9 antibody, and HD37, a CD19 antibody.
- CD9 and CD19 antibodies, as well as other unclustered antibodies may also be useful in this purging process in combination with WCMH15.14.
- Antibody WCMH15.14 along with other CALLA antibodies have been used to phenotype malignant cells from patients with leukemia and lymphomas. It has been clearly established through many published studies (see, for example,

Abstract
L'invention a trait à une nouvelle lignée cellulaire ainsi qu'à l'anticorps monoclonal produit par ladite lignée cellulaire. Ledit nouvel anticorps monoclonal se lie avantageusement et spécifiquement à l'antigène de la leucémie lymphotique aiguë. On peut par conséquent utiliser cet anticorps pour la détection de la leucémie infantile ainsi que dans des interventions thérapeutiques telles que la purge de moëlle osseuse. On peut aussi utiliser le nouvel anticorps monoclonal pour former des protéines de toxines hybrides capables de chercher et d'éliminer sélectivement des cellules cibles.
