The invention provides further characterization of the disease and cancer-associated antigen, transferrin receptor. The invention also provides a novel family of antibodies that bind to the transferrin receptor, methods of diagnosing and treating various human cancers and diseases that express transferrin receptor.

Claims (24)

1. A method for delivering a chemotherapeutic agent to a cancer cell comprising administering a composition comprising an antibody or antigen-binding fragment thereof, wherein said antibody or fragment comprises three complementarity determining regions from the light chain and three complementarity determining regions from the heavy chain, said antibody or fragment thereof is capable of binding to LUCA31 epitope which does not overlap with transferrin binding, and said LUCA31 epitope is the epitope bound by antibody expressed by hybridoma cell line having ATCC No. PTA-6055, associated with the chemotherapeutic agent, wherein the cancer cell is selected from the group consisting of cancer cells from adrenal gland tumors, AIDS-associated cancers, alveolar soft part sarcoma, astrocytic tumors, bladder cancer, bone cancer, brain and spinal cord cancers, metastatic brain tumors, breast cancer, carotid body tumors, cervical cancer, chondrosarcoma, chordoma, chromophobe renal cell carcinoma, clear cell carcinoma, colon cancer, colorectal cancer, cutaneous benign fibrous histiocytomas, desmoplastic small round cell tumors, ependymomas, Ewing's tumors, extraskeletal myxoid chondrosarcoma, fibrogenesis imperfecta ossium, fibrous dysplasia of the bone, gallbladder and bile duct cancers, gestational trophoblastic disease, germ cell tumors, head and neck cancers, islet cell tumors, Kaposi's sarcoma, kidney cancer, leukemias, lipoma/benign lipomatous tumors, liposarcoma/malignant lipomatous tumors, liver cancer, lymphomas, lung cancer, medulloblastoma, melanoma, meningiomas, multiple endocrine neoplasia, multiple myeloma, myelodysplastic syndrome, neuroblastoma, neuroendocrine tumors, ovarian cancer, pancreatic cancers, papillary thyroid carcinomas, parathyroid tumors, pediatric cancers, peripheral nerve sheath tumors, phaeochromocytoma, pituitary tumors, prostate cancer, uveal or intraocular melanoma, renal metastatic cancer, rhabdoid tumor, rhabdomysarcoma, sarcomas, skin cancer, soft-tissue sarcomas, squamous cell cancer, stomach cancer, synovial sarcoma, testicular cancer, thymic carcinoma, thymoma, thyroid metastatic cancer, and uterine cancers.

2. The method of claim 1 , wherein the chemotherapeutic agent is administered to an individual.

3. The method of claim 1 , wherein the antibody is an antibody expressed by hybridoma ATCC No. PTA-6055 or progeny thereof.

4. A method of inhibiting growth of cancer cells in an individual comprising administering to the individual an effective amount of a composition comprising an antibody or antigen-binding fragment thereof, wherein said antibody or fragment comprises three complementarity determining regions from the light chain and three complementarity determining regions from the heavy chain, said antibody or fragment thereof is capable of binding to LUCA31 epitope which does not overlap with transferrin binding, and said LUCA31 epitope is the epitope bound by antibody expressed by hybridoma cell line having ATCC No. PTA-6055, associated with a chemotherapeutic agent to the individual, wherein the cancer cells are selected from the group consisting of cancer cells from adrenal gland tumors, AIDS-associated cancers, alveolar soft part sarcoma, astrocytic tumors, bladder cancer, bone cancer, brain and spinal cord cancers, metastatic brain tumors, breast cancer, carotid body tumors, cervical cancer, chondrosarcoma, chordoma, chromophobe renal cell carcinoma, clear cell carcinoma, colon cancer, colorectal cancer, cutaneous benign fibrous histiocytomas, desmoplastic small round cell tumors, ependymomas, Ewing's tumors, extraskeletal myxoid chondrosarcoma, fibrogenesis imperfecta ossium, fibrous dysplasia of the bone, gallbladder and bile duct cancers, gestational trophoblastic disease, germ cell tumors, head and neck cancers, islet cell tumors, Kaposi's sarcoma, kidney cancer, leukemias, lipoma/benign lipomatous tumors, liposarcoma/malignant lipomatous tumors, liver cancer, lymphomas, lung cancer, medulloblastoma, melanoma, meningiomas, multiple endocrine neoplasia, multiple myeloma, myelodysplastic syndrome, neuroblastoma, neuroendocrine tumors, ovarian cancer, pancreatic cancers, papillary thyroid carcinomas, parathyroid tumors, pediatric cancers, peripheral nerve sheath tumors, phaeochromocytoma, pituitary tumors, prostate cancer, uveal or intraocular melanoma, renal metastatic cancer, rhabdoid tumor, rhabdomysarcoma, sarcomas, skin cancer, soft-tissue sarcomas, squamous cell cancer, stomach cancer, synovial sarcoma, testicular cancer, thymic carcinoma, thymoma, thyroid metastatic cancer, and uterine cancers.

5. The method of claim 4 , wherein the chemotherapeutic agent is delivered into the cancer cells.

6. The method of claim 4 , wherein the antibody is expressed by hybridoma ATCC No. PTA-6055 or progeny thereof.

7. The method of claim 1 , wherein the antibody comprises an antigen-binding fragment of the antibody expressed by the hybridoma ATCC No. PTA-6055 or progeny thereof.

8. The method of claim 1 , wherein the antibody comprises the three complementarity determining regions from the light chain and the three complementarity determining regions from the heavy chain of antibody LUCA31 expressed by the hybridoma having ATCC No. PTA-6055 or progeny thereof.

9. The method of claim 8 , wherein the antibody is a chimeric antibody.

10. The method of claim 8 , wherein the antibody is a humanized antibody.

11. The method of claim 8 , wherein the antibody is a chimeric antibody comprising the heavy chain and the light chain variable region sequences from antibody LUCA31 produced by the cell line having ATCC No. PTA-6055 or progeny thereof.

12. The method of claim 11 , wherein the antibody comprises the heavy chain constant region sequence and the light chain constant region sequence from a human antibody.

13. The method of claim 1 , wherein the antibody comprises the heavy chain variable region sequence from antibody LUCA31 produced by the cell line having ATCC No. PTA-6055 or progeny thereof.

14. The method of claim 1 , wherein the antibody comprises the light chain variable region sequence from antibody LUCA31 produced by the cell line having ATCC No. PTA-6055 or progeny thereof.

15. The method of claim 8 , wherein the antibody comprises an antigen-binding fragment; wherein the antigen-binding fragment is selected from the group consisting of a Fab, a Fab′, a F(ab′)2 and a Fv; and wherein the antigen-binding fragment retains the binding specificity of antibody LUCA31 produced by the cell line having ATCC No. PTA-6055 or progeny thereof.

16. The method of claim 4 , wherein the antibody comprises an antigen-binding fragment of the antibody expressed by the hybridoma ATCC No. PTA-6055 or progeny thereof.

17. The method of claim 4 , wherein the antibody comprises the three complementarity determining regions from the light chain and the three complementarity determining regions from the heavy chain of antibody LUCA31 expressed by the hybridoma having ATCC No. PTA-6055 or progeny thereof.

18. The method of claim 17 , wherein the antibody is a chimeric antibody.
