Following a description of the characteristics of the human high molecular weight-melanoma associated antigen (HMW-MAA), the rationale to use anti-idiotypic (anti-id) monoclonal antibodies (mAb) as immunogens to implement active specific immunotherapy in patients with malignant diseases is discussed. Among the anti-id mAb developed in this laboratory the mAb MK2-23, which had been elicited with the syngeneic anti-HMW-MAA mAb 763.74, has been shown with serological and immunochemical assays to bear the mirror image of the determinant recognized by mAb 763.74 on HMW-MAA. The anti-id mAb elicited humoral anti-HMW-MAA immunity in about 60% of patients with malignant melanoma. The immunogenicity of mAb MK2-23 is markedly enhanced by conjugation to a carrier and administration with an adjuvant, but is not affected by the administration of low doses of cyclophosphamide. Development of anti-HMW-MAA immunity in patients with malignant melanoma is associated with survival prolongation. These results in conjunction with the lack of major side effects in spite of repeated administrations of mAb MK2-23 suggest that active specific immunotherapy with mAb MK2-23 represents a useful therapeutic approach to malignant melanoma.

UI MeSH Term Description Entries
D008545 Melanoma A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.
