Appl. No.:

10/461878

Inventors:

David V. Gold - Metuchen NJ, US
David M. Goldenberg - Mendham NJ, US
Hans J. Hansen - Picayune MS, US

Assignee:

Immunomedics, Inc. - Morris Plains NJ

International Classification:

C07K 16/00

US Classification:

5303873, 530350, 530380, 530385, 5303871, 5303877, 5303881, 4241341, 4241351, 4241411, 4241551, 4241421, 4241781, 424 851, 435 79, 435188, 4353201

Abstract:

This invention relates to monovalent and multivalent, monospecific antibodies and to monovalent and multivalent, multispecific antibodies. One embodiment of these antibodies has one or more identical binding sites where each binding site binds with a target antigen or an epitope on a target antigen. Another embodiment of these antibodies has two or more binding sites where these binding sites have affinity towards different epitopes on a target antigen or different target antigens, or have affinity towards a target antigen and a hapten. The present invention further relates to recombinant vectors useful for the expression of these functional antibodies in a host. More specifically, the present invention relates to the tumor-associated antibody designated PAM4. The invention further relates to chimeric PAM4 antibodies, and the use of such antibodies in diagnosis and therapy.

Appl. No.:

11/752152

Inventors:

David P. Gold - New York NY, US

International Classification:

G06F 17/30

US Classification:

707737, 705311

Abstract:

In a method for organizing information in a database, abstractions are separated from expressions of the abstractions to obtain a first set of information corresponding to the abstractions and a second set of information corresponding to at least one set of characteristics relating to the expressions of the abstractions. Each abstraction is arranged within the first set of information hierarchically within the database. Each set of characteristics relating to an expression of an abstraction within the second set of information is associated with an abstraction within the database.

International Classification:

A61K 39/395

US Classification:

4241331, 5303871

Abstract:

Described herein are compositions and methods of use of anti-pancreatic cancer antibodies or fragments thereof, such as murine, chimeric, humanized or human PAM4 antibodies. The subject antibodies show a number of novel and useful therapeutic characteristics, such as binding with high specificity to pancreatic and other cancers, but not to normal or benign pancreatic tissues and binding to a high percentage of early stage pancreatic cancers. In preferred embodiments, the antibodies bind to pancreatic cancer mucins. The antibodies and fragments are of use for the detection, diagnosis and/or treatment of cancer, such as pancreatic cancer. The antibodies, such as PAM4 antibodies, bind to a PAM4 antigen that shows unique cell and tissue distributions compared with other known antibodies such as CA19. 9, DUPAN2, SPAN1, Nd2, B72. 3, and Leand Le(y) antibodies that bind to the Lewis antigens.

International Classification:

US Classification:

435 71, 5303871

Abstract:

Described herein are compositions and methods of use of anti-pancreatic cancer antibodies or fragments thereof, such as murine, chimeric, humanized or human PAM4 antibodies. The antibodies show novel and useful diagnostic characteristics, such as binding with high specificity to pancreatic and other cancers, but not to normal or benign pancreatic tissues and binding to a high percentage of early stage pancreatic cancers. Preferably, the antibodies bind to pancreatic cancer mucins such as MUC1 or MUC5ac and are of use for the detection and diagnosis of early stage pancreatic cancer. In more preferred embodiments, the anti-pancreatic cancer antibodies can be used for immunoassay of serum samples, wherein the immunoassay detects a marker for early stage pancreatic cancer in serum. Most preferably, the serum is extracted with an organic phase, such as butanol, before immunoassay. Alternatively, immunoassay with PAM4 and anti-CA19.
