The disclosure is directed to dual variable domain immunoglobulin double-stranded RNA conjugates that are advantageous for inhibition of target gene expression, as well as compositions suitable for therapeutic use. The dual variable domain immunoglobulin comprises a first variable domain that binds to a binding target, and a second variable domain that comprises a reactive residue, where the linker is covalently conjugated to the reactive residue. The dsRNA is linked to the linker and is capable of inhibiting the expression of the target gene by RNA interference. The disclosure also provides pharmaceutical compositions comprising these conjugate and methods of inhibiting the expression of a target gene by administering these conjugates, e.g., for the treatment of various disease conditions.

The present disclosure relates to benzoselenophene-based compounds, method of preparing the benzoselenophene-based compounds, pharmaceutical compositions and antibody-drug conjugates including the benzoselenophene-based compounds.

This invention, inter alia, relates to CD19 binding agents and methods of using such CD19 binding agents for treating disease.

The invention relates to novel benzodiazepine derivatives with antiproliferative activity and more specifically to novel benzodiazepine compounds of formula (I)-(VII). The invention also provides conjugates of the benzodiazepine compounds linked to a cell-binding agent. The invention further provides compositions and methods useful for inhibiting abnormal cell growth or treating a proliferative disorder in a mammal using the compounds or conjugates of the invention.

The invention provides anti-CLL-1 antibodies and immunoconjugates and methods of using the same.

The present invention relates to an antibody-drug-conjugate. From one aspect, the invention relates to an anti-body-drug-conjugate comprising an antibody capable of binding to a Target, said antibody being conjugated to at least one drug selected from derivatives of dolastatin 10 and auristatins. The invention also comprises method of treatment and the use of said anti-body-drug-conjugate for the treatment of cancer.

A conjugate of formula I:
L-(D.sup.L).sub.P  (1) wherein L is a Ligand unit, D.sup.L is a Drug Linker unit of formula II: ##STR00001## wherein either: (a) R.sup.10 and R.sup.11 form a nitrogen-carbon double bond between the nitrogen and carbon atoms to which they are bound; or (b) R.sup.11 is OH, and R.sup.10 is: ##STR00002## p is an integer of from 1 to 20.

Provided herein are antibody conjugates with binding specificity for CD74 and compositions comprising the antibody conjugates, including pharmaceutical compositions, methods of producing the conjugates, and methods of using the conjugates and compositions for therapy.

Site-specific antibody-drug conjugates are described, in particular conjugates comprising pyrrolobenzodiazepines (PBDs) having a labile protecting group in the form of a linker. The site of conjugation, along with modification of the antibody moiety, allows for improved safety and efficacy of the ADC.

The disclosure provides conjugates of an isolated humanized anti-CD22 antibody and PBD dimers.
