The present invention provides a novel antibody-pyrrolodiazepine derivative and a novel antibody-pyrrolodiazepine derivative conjugate using the same, and a novel CLDN6 and/or CLDN9 antibody.

Methods of treating a tumor by administering a claudin-6 (CLDN6) or CLDN9 antibody-pyrrolobenzodiazepine derivative conjugate

Provided are novel antibody-pyrrolodiazepine derivative and novel antibody-pyrrolodiazepine derivative conjugates, as well as methods of using the same, and a novel CLDN6 and/or CLDN9 antibody. The disclosed compounds are of the class of alkyl benzene sulfonyl ureas, useful as oral anti-diabetics, and include substituted benzo[e]pyrrolo[1,2-α][1,4]diazepine.

Antibody-drug conjugates comprising substituted benzo[e]pyrrolo[1,2-a][1,4]diazepines

It is an object to provide an antibody specifically binding to CD37-positive tumor cells such as malignant B-cell lymphoma, an antibody-drug conjugate comprising the antibody, a pharmaceutical composition having therapeutic effects on a tumor using the antibody, a method for treating a tumor using the aforementioned pharmaceutical composition, a method for producing the antibody, and a method for producing the antibody-drug conjugate, and the like. The present invention provides an anti-CD37 antibody-drug conjugate in which an antibody is conjugated to a drug linker represented by the following formula (wherein A represents a connecting position to the antibody) by a thioether bond, specifically, a humanized anti-CD37 antibody having internalization ability and an antibody-drug conjugate containing the antibody.

Anti-CD37 antibody-drug conjugate

A novel antibody-pyrrolodiazepine derivative and a novel antibody-pyrrolodiazepine derivative conjugate using the same, comprising substituted benzo[e]pyrrolo[1,2-a][1,4]diazepines represented by the [Formula 24], [Formula 25], [Formula 26], and/or [Formula 27].

Antibody-drug conjugates comprising substituted benzo[e]pyrrolo[1,2-&#x3b1;][1,4]diazepines

Antibody-pyrrolobenzodiazepine derivative conjugate and method of use thereof for treating a tumor

It is an object of the present invention to provide an antibody specifically binding to GPR20-positive tumor cells such as GIST, a pharmaceutical product comprising the antibody and having therapeutic effects on a tumor, a method for treating a tumor using the aforementioned pharmaceutical product, and the like. It is another object of the present invention to provide an anti-GPR20 antibody having internalization activity, an antibody-drug conjugate containing the antibody, and the like.
