Definitions

  • the present application relates to novel, directed against the target C4.4a binder-drug conjugates (ADCs) of ⁇ , ⁇ -dialkylauristatins, active metabolites of these ADCs, methods for producing these ADCs, the use of these ADCs for the treatment and / or prevention of Diseases and the use of these ADCs for the preparation of medicaments for the treatment and / or prevention of diseases, especially hyperproliferative and 7 or angiogenic diseases such as cancer.
  • Such treatments may be monotherapy or in combination with other medicines or other therapeutic measures.
  • Cancers are the result of uncontrolled cell growth in a variety of tissues, in many cases the new cells invade existing tissues (invasive growth) or they metastasize to distant organs. Cancers occur in various organs and often have tissue-specific disease courses. Therefore, the term cancer as a generic term describes a large group of defined diseases of various organs, tissues and cell types.
  • chemotherapeutic agents administered parenterally today are often not targeted to tumor tissue or tumor cells, but are nonspecifically distributed in the body by systemic administration, i. even in places where drug exposure is undesirable, such as in healthy cells, tissues, and organs. This can lead to unwanted side effects and even serious general toxic effects, which then often severely limit the therapeutically usable dose range of the active substance or require a complete cessation of the medication.
  • trastuzumab Herceptin
  • rituximah Renillab
  • cetuximab Erbitux
  • bevacizumab Avastin
  • small molecule drug binders can also be used as binders that selectively bind to a particular target, such as a receptor [see, e.g. E. Ruoslahti et al., Science 279, 377-380 (1998); D. Karkan et al., PLoS ONE 3 (6), e2469 (June 25, 2008)]. Also known are conjugates of cylotoxic agent and addressing ligand, which have a defined cleavage site between ligand and drug to release the drug.
  • target breakpoint may be, for example, in a peptide chain which can be selectively cleaved at a particular site by a specific enzyme at the site of action [see, e.g. R. A, Firestone and L.A. Telan, US Patent Application US 2002/0147138].
  • C4.4a (gene: LYPD3) was first described as a metastasis-associated cell surface protein in rat pancreatic tumor cells (R Harborl M. et al., Oncogene 1998, 17 (15): 1989-2002). Human C4.4a was isolated from its placental cDNA library (Würfel, J. et al., Gene 2001, 262: 35-41). C4.4a shows structural homology to the uPA receptor and contains two LY6 domains that share the typical three-finger folding motif and are linked by 9 disulfide bonds (Jacobsen B.
  • C4.4a is anchored in the cell via glycophosphatidylinositol (GPI).
  • GPI glycophosphatidylinositol
  • the protein is highly glycosylated and contains numerous - and O- glycosylation sites.
  • C4.4a shows strong expression in tumor cells of lung cancer, colon cancer, breast cancer, uterine cancer pancreatic cancer, kidney cancer, head and neck tumors and melanoma.
  • RNA analyzes showed C4.4a expression in - 50% of primary lung tumors and -75% of lung cancer metastases, whereas expression in healthy lung tissue was undetectable (Würfel J. et al., Gene 2001, 262: 35- 41).
  • C4.4a can be used as a prognostic marker, with high C4.4a expression correlating with poor prognosis (Hansen L. et al ,, Lung Cancer 2007, 58: 260-266).
  • colon cancer C4.4a is cleaved off the tumor cell surface and can be used as a prognostic serum marker (Konishi, K., et al., Cancer Science 2010).
  • a detailed expression analysis of melanoma revealed that C4.4a is present in ⁇ 60% of the primary malignancies Melanoma and is expressed in 100% of lymph node and skin metastases (sammlungr S. et al., Juvest Dermatol., 2001, 116 (2): 344-347).
  • C4.4a is an ideal target for tumor therapy because C4.4a expression in healthy tissues is restricted to skin keratinocytes and esophageal endothelial cells as well as placental cells (Würfel J. et al., Gene 2001, 262: 35-41).
  • WO01 / 23553 describes the use of a C4.4a inhibitor (eg an anti-C4.4a antibody) which can inhibit C4.4a expression or activity in cancer therapy. The exact function of C4.4a is unknown.
  • C4.4a is thought to play a role in tumor cell invasion, presumably through interaction with the extracellular matrix (Renderl M, et al., Oncogene 1998, 17 (15): 1989-2002; Paret C. et al. British Journal of Cancer 2007, 97: 1146-1156).
  • Potential ligands are laminin I and 5, as well as galectin 3 (Paret C, Int J. Cancer 2005, 115: 724-733).
  • Auristatin E (AE) and monomethylauristatin E (MMAE) are synthetic analogues of the statins, a special group of linear pseudopeptides originally isolated from marine sources, some of which have very potent cytotoxic activity against tumor cells [for a review, see, eg GR Pettit, Prague. Chem. Org. Prod. 70, 1-79 (1997); GR Pettit et al, Anti-Cancer Dr g Design 10, 529-544 (1995); GR Pettit et al, AntiCancer Drug Design 13, 243-277 (1998) 1.
  • MMAE Monomethylauristatin E
  • MMAE has the disadvantage of a comparatively high systemic toxicity.
  • MMAE is used in particular in conjunction with enzymatically cleavable valine citrulline linkers in the ADC setting for more targeted tumor therapy [WO 2005/081711-A2; S.O. Doronina et al., Bioconjugate Chem. 17, 114-124 (2006)].
  • MMAE is preferably released intracellularly from corresponding ADCs.
  • MMAE is in an application in the form of (ADCs) not compatible with linker (linker) between antibody and drug, which have no enzymatically cleavable target breakpoint [SO Doronina et al., Bioconjugate Chem. 17, 114-124 (2006)].
  • Monomethylauristatin F is an auristatin derivative having a C-terminal phenylalanine moiety which has only moderate anti-proliferative activity compared to MMAE. This is most likely due to the free carboxyl group which, due to its polarity and charge, adversely affects the cellularity of this compound.
  • MMAF-OMe methyl ester of MMAF
  • MMAF-OMe methyl ester of MMAF
  • MMAF-OMe has been described as a neutrally charged, prodrug prodrug, which has several orders of magnitude increased in vitro cytotoxicity to various carcinoma cell lines compared to MMAF [SO Doronina et al., Bioconjugate Chem. 17, 114-124 (2006)]. It is believed that this effect is caused by MMAF itself, which is rapidly released by intracellular ester hydrolysis after uptake of the prodrug into the cells.
  • active compound compounds based on simple ester derivatives are generally subject to the risk of chemical instability as a result of unspecific ester hydrolysis independent of the intended site of action, for example by esterases present in the blood plasma; this can significantly limit the applicability of such compounds in therapy.
  • MMAF Monomethylauristatin F
  • auristatin analogues with a C-terminal, amidically substituted phenylalanine unit are described in WO 01/18032-A2.
  • WO 02/088172-A2 and WO 2007/008603-A1 claim MMAF analogs which relate to side-chain modifications of phenylalanine, and in WO 2007/008848-A2 those in which the carboxyl group of phenylalanine is modified , Auristatin conjugates linked via the C-terminus have recently been described in WO 2009/1 17531 -AI [see also S.O. Doronina et al., Bioconjugate Chem. 19, 1960-1963 (2008) 1.
  • auristatin derivatives such as MMAE and MMAF are also substrates for transporter proteins which are expressed by many tumor cells, which can lead to a development of resistance to these active substances.
