Effector conjugates, process for their production and their pharmaceutical use

This application is a divisional of U.S. patent application Ser. No. 10/631,011 filed on Jul. 31, 2003, which claims the benefit of U.S. patent application Ser. No. 60/451,673 filed on Mar. 5, 2003, both of which are fully incorporated by reference herein.

The development of the understanding relating to the recognition of binding regions, especially in the field of monoclonal antibodies or fragments thereof against specific tumor antigens, makes it possible to consider a selective tumor therapy by specific release of an anti-tumor active agent at the target site.

A precondition for such an approach, in which a highly active (toxic) active agent (effector) is coupled to a high-molecular, tumor-specific recognition unit, such as, for example, to an antibody, is a substantial inactivity of the conjugate, whose minimum components are represented by a recognition unit and an effector, until it has reached the target site (tumor). Arriving at the target site, the conjugate binds to the cell surface and the active ingredient, optionally after the preceding internalization of the entire complex, can be released.

The successful therapy of solid tumors, especially with monoclonal antibodies, can be limited, however, by an inadequate penetration of the antibody into the tumor as well as the heterogeneous dispersion of the corresponding tumor-associated antigens in the tumor tissue.

These limitations could be avoided in that the tumor-vascular system is attacked in a specific way. The growth of tumors below a volume of about 2 mm 3 depends on a neoangiogenesis. The subsequent tumor growth is based on an intact vascular system, which ensures the supply with nutrients or the removal of waste products. The selective destruction of this system should therefore result in a necrosis of the tumor. The attack on the vascular system of the tumor promises a number of advantages relative to the direct attack on the tumor itself. In comparison to tumor cells, endothelial cells are easier to access, since no tumor tissue has to be penetrated. The damage of an individual tumor vessel should result in a necrosis of thousands of tumor cells. To damage a tumor vessel, it is not necessary to kill all endothelial cells. The specific attack of endothelial cells in or close to the tumors minimizes systemic side effects. Endothelial cells are genetically very stable, so that the probability of a development of resistance against the tumor therapeutic agent is low.

Within the scope of this invention, surprisingly enough, a possibility has now been found to link the chemically very sensitive, highly-functionalized class of active agents of epothilones and analogs thereof to a high-molecular recognition unit via different linkers in different positions of the active agent.

The object of this invention is thus, inter alia,

1. to find a method to link highly active agents from the structural class of the epothilones and epothilone derivatives with suitable linkers, 2. to synthesize suitable linkers, 3. to develop a method to link these epothilone-linker conjugates to recognition units, such as, for example, monoclonal antibodies or fragments thereof, to form immune conjugates that are both chemically and metabolically sufficiently stable for the development of a pharmaceutical, and that are superior to the epothilones or epothilone derivatives that are taken as a basis with respect to their therapeutic range, their selectivity of action and/or undesirable toxic side effects and/or the degree of their activity.

This invention accordingly comprises effector conjugates of general formula I

Thionylation of a Complete Immunoglobuline (IgG), e.g., the 2H8 Antibody

For the introduction of thionyl groups an amine-free solution of the 2H8 antibody in phosphate buffer having a concentration in the range of about 1-10 mg/ml at a pH of 7.2 is mixed with the 10- to 100-fold excess of 2-iminothiolane and is allowed to react for 1 hour at 23° C. The number of the introduced thiol groups is 1 to about 15 depending on the excess of reagent.
