Definitions
- Trop-2 (AC: P09758) is a molecule that transduces a signal that determines an increase in cytoplasmic calcium 1 and it is involved in cell-cell and cell/matrix adhesion in epithelial tissues.
- Trop-2 is also known as tumor-associated calcium signal transducer 2 (TACSTD-2) 2i 3 , GA733- 1 , EGP, MR23, MR54, RS-7 e T16 4 6 .
- Trop-2 localizes all along the membrane in epithelial cells 4 .
- the extracellular domain of Trop-2, globular portion contains an EGF-like domain, followed by a thyroglobulin domain and it is involved in cell adhesion.
- Metastatic spreading is the main cause of death in the majority of cancers in man 10 .
- Common tumors such as for example colon, breast and lung cancers in many cases have already generated metastases at the time of surgery. Metastatic tumors are often resistant to most of the currently available therapeutic attempts 10 .
- TROP2 is the only gene that is overexpressed in metastatic cells in different experimental systems.
- a large-scale analysis of Trop-2 expression in human primary cancers and their corresponding metastases revealed Trop-2 overexpression in the metastases from colon, stomach, breast and ovary tumors. This was confirmed by Northern and Western blot and by immunohistochemistry ( Figure 1 and Tables 1 , 2).
- AR47A6.4.2 monoclonal antibody showed efficacy against a single type of tumor (BxPC-3) at an advanced stage of growth, already growing in the experimental animal, which is considered to be the most stringent and reliable test of the activity on experimental tumors.
- the AR47A6.4.2 monoclonal antibody was obtained by the immunization of mice with tissue from an ovarian tumor, i.e. without selecting for reactivity against specific and different portions of the Trop-2 molecule. As in the case of the RS7 antibody this prevents the sinergic and personalized use of the different monoclonal antibodies, i.e. using the best monoclonal antibody for each individual tumor, as determined by the post-translational modifications of Trop-2 and by the ability of this molecule to generate intracellular signals that control tumor growth..
- anti-tumor monoclonal antibodies es. targetted against Her2/neu
- anti-tumor monoclonal antibodies are directed against specific portions of the molecule, so as to avoid specific conformational changes or interactions with other signalling molecules, which play a fundamental role in determining the antitumor therapeutic efficacy 12 .
- Another important aspect is the possibility to have multiple antibodies, which do not compete for the binding to Trop-2. This makes it possible to bind higher numbers of tumor cells, when the targets of the individual antibodies (epitopes in technical terms) are selectively expressed at different development or differentiation stages of the tumor. Moreover this allows for the simultaneous binding of a higher number of antibody molecules to their target, with a corresponding increase in efficacy.
- the authors of the present invention have now prepared new anti-
- Trop-2 monoclonal antibodies which are homogeneous and with high affinity and which are targeted against different regions of the molecule ( Figures 4 and 5), at variance with the antibodies already known, for an efficient utilization in biomedical applications.
- the anti-Trop-2 antibodies taught by the present invention are active against the growth of multiple types of tumors such as for example Colo-205, HCT-116 and HT29 colon cancers; SKOV ovarian cancer; SKBR3 and MDA MB468 breast cancer.
- the antibodies taught by the present invention have a higher anti-tumor activity with respect to prior art RS7 antibodies, as shown in experimental models of human tumors injected in immuno-depressed mice ( Figure 6).
- a pivotal point of the anti-Trop-2 hybridoma isolation strategy was the selection procedure of the hybridoma cell populations for their specific reactivity against TROP2-transfected L cells and absence of reactivity against empy-vector control L transfectants, which made the screening procedure both stringent and effective. This screening procedure was performed by cytofluohmetry or ELISA tests on transfected or non transfected L cells. The procedures employed in the present invention make use of
- the monoclonal antibodies were then selected that proved to be the best/most effective in vivo 4 , reaching essentially the complete inhibition of tumor growth ( Figures 6 and 7).
- the antibodies taught by the present invention showed a higher efficacy with respect to the RS7 antibody ( Figure 6).
- the antibody used in these experiments is the mRS7 monoclonal antibody, as taught in the patent submission WO03/074566, and shown in this same submissiont to have the same affinity and binding activity as the cRS7 ed hRS7 variants.
