    摘要: The invention relates to a saponin derivative based on a saponin comprising a triterpene aglycone and a first saccharide chain and/or a second saccharide chain, and comprising: an aglycone core structure comprising an aldehyde group which has been derivatised; and/or the first saccharide chain wherein the first saccharide chain comprises a carboxyl group, which has been derivatised; and/or the second saccharide chain wherein the second saccharide chain comprises at least one acetoxy group which has been derivatised. The invention also relates to a first pharmaceutical composition comprising the saponin derivative of the invention. In addition, the invention relates to a pharmaceutical combination comprising the first pharmaceutical composition of the invention and a second pharmaceutical composition comprising any one or more of an antibody-toxin conjugate, a receptor-ligand – toxin conjugate, an antibody-drug conjugate, a receptor-ligand – drug conjugate, an antibody-oligonucleotide conjugate or a receptor-ligand – oligonucleotide conjugate. The invention also relates to the first pharmaceutical composition or the pharmaceutical combination of the invention, for use as a medicament, or use in the treatment or prophylaxis of a cancer, an infectious disease, viral infection, hypercholesterolemia, primary hyperoxaluria, haemophilia A, haemophilia B, alpha-1 antitrypsin related liver disease, acute hepatic porphyria, transthyretin-mediated amyloidosis, or an auto-immune disease. Furthermore, the invention relates to an in vitro or ex vivo method for transferring a molecule from outside a cell to inside said cell, comprising contacting said cell with the molecule and with a saponin derivative of the invention.

    摘要: The present disclosure provides for dosing regimens for the treatment of patients with cancer, particularly a HER2-expressing cancer, with an anti-HER2 antibody-drug conjugate (ADC). The present disclosure further provides for methods for the treatment of patients with cancer in which an anti-HER2 ADC is administered. In one embodiment, the anti-HER2 ADC is T(kK183C+K290C)-vc0101 (PF-06804103), in which the antibody T(kK183C+K290C) is linked to the auristatin drug 2-methylalanyl-N-[(3R,4S,5S)-3-methoxy-l-{(2S)-2-[(1R,2R) -1-methoxy-2-methyl-3-oxo-3-{[(1S)-2-phenyl-1-(1,3-thiazol-2-yl) ethyl]amino}propyl]pyrrolidin-1-yl}-5-methyl-1-oxoheptan-4-yl]-N- methyl-L-valinamide (also known as "0101") via the cleavable linker maleimidocaproyl-valine-citrulline-p-aminobenzyloxycarbonyl (also known as "vc").
