The present invention relates to non peptidic, heterobivalent molecules (HBM) that are able to simultaneously bind a surface target protein as well as an endogenous or exogenous human antibody protein and induce immune effector function. More specifically, the present invention relates to agents capable of binding to a chemokine receptor and inducing the depletion of chemokine receptor positive subsets of pathogenic cells in a subject for use in the treatment and/or prevention of cancer, inflammatory, autoimmune and allergic disease.

The invention relates to a Prodrug activation method, for therapeutics, wherein use is made of abiotic reactive chemical groups that exhibit bio-orthogonal reactivity towards each other. The invention also relates to a Prodrug kit comprising at least one Prodrug and at least one Activator, wherein the Prodrug comprises a Drug and a first Bio-orthogonal Reactive Group (the Trigger), and wherein the Activator comprises a second Bio-orthogonal Reactive Group. The invention also relates to targeted therapeutics used in the above-mentioned method and kit. The invention particularly pertains to antibody-drug conjugates and to bi- and trispecific antibody derivatives.

The invention provides a CLIPTAC comprising: (a) a first portion comprising a ligand for an intracellular target protein; (b) a second portion comprising a ligand for an E3 ubiquitin ligase; and (c) a linker portion covalently coupling the first and second portions; wherein the linker comprises a covalent bond produced by a bioorthogonal click reaction between a compatible pair of reactive moieties. CLIPTAC precursor compositions and CLIPTAC precursors are also provided, together with pharmaceutical compositions comprising the CLIPTAC, CLIPTAC precursor compositions and CLIPTAC precursors, and methods of treatment using the same.

The present invention relates to an antibody drug conjugate using a bispecific antibody and its use. The antibody drug conjugate of the present invention can easily form a conjugate of an antibody and a drug without a multistep synthetic process though binding of a conjugate of a bivalent cotinine-peptide and a drug, and an anti-cotinine single chain variable fragment. In addition, the antibody drug conjugate can effectively deliver a drug to a target to which the antibody binds specifically, and can enhance a half-life of a drug in the body, thereby improving a therapeutic effect.

The present application relates to antibodies that bind to small molecules such as cyclophosphamide, ifosfamide, and analogs thereof, and immunological assays for determining the presence and/or quantifying the amount of cyclophosphamide and/or ifosfamide in a sample. By way of example, such immunological assays can be used for environmental testing.

A bioorthogonal molecule can include a molecule having a structure according the above wherein R.sup.1-R.sup.8 are independently selected from H, a substituted or unsubstituted C.sub.1-C.sub.4 alkyl or alkylene group, COOH, COOR.sup.9, COR.sup.9, CONR.sup.9R.sup.10, CN, CF.sub.3, and SO.sub.2R.sup.9, and where R.sup.9 and R.sup.10 are independently selected from H and a substituted or unsubstituted C.sub.1-C.sub.4 alkyl or alkylene group, with the proviso that one of R.sup.3-R.sup.8 comprises a leaving group, and wherein X is O, S, N, SO, SO.sub.2, SR.sup.+, Se, PO.sub.2.sup., or NRR.sup.+, and where R and R are independently selected from H or a substituted or unsubstituted C.sub.1-C.sub.4 alkyl or alkylene group.
