or a pharmaceutically acceptable salt thereof, processes for the preparation of these compounds, compositions containing these compounds, and the uses of these compounds.

An anti-PD-L1 antibody, or an antigen-binding fragment thereof, comprising: a heavy chain variable region comprising the three CDRs with the sequences of SEQ ID NOs: 2-4, 6-8, 10-12, 14-16, or 18-20; and/or a light chain variable region comprising the three CDRs with the sequences of SEQ ID NOs: 22-24, 26-28, 30-32, 34-36, or 38-40, wherein the antibody is a chimeric, humanized, composite, or human antibody.

ALK5 inhibitor compounds, conjugates, and pharmaceutical compositions for use in the treatment of disease, such as cancer, are disclosed herein. The disclosed compounds are useful, among other things, in the treating of cancer and fibrosis and modulating ALK5. Additionally, compounds incorporated into a conjugate with an antibody construct are described herein.

The invention relates to conjugates of biologically active compounds, wherein such a conjugate is comprised of a sequence of amino acids containing a tripeptide that confers selective cleavage by tumor tissue homogenate for release of free drug and/or improves biodistribution into the tumor tissue in comparison to normal tissue homogenate from the same species, wherein the normal tissue is the site of an adverse event associated with administration to a human subject in need thereof of a therapeutically effective amount of a comparator conjugate whose amino acid sequence is a dipeptide known to be selectively cleavable by Cathepsin B.

Various conjugates and compositions thereof are disclosed for use in the treatment of a liver disease, such as liver cancer and liver fibrosis. The compositions comprise conjugates, wherein the conjugates are comprised of an antibody or antibody construct specific for ASGR1 or ASGR2 attached to a TGFβR1 inhibitor via a linker. Additionally provided are the methods of preparation of the conjugates and compositions thereof.

The invention relates to binding molecules that bind specifically to prostate specific membrane antigen (PSMA), in particular, single human variable heavy chain domain antibodies and related methods for treatment of cancer.

Compositions comprising a fatty acid oil mixture and at least one free fatty acid, and uses thereof are disclosed. Further disclosed are preconcentrates capable of forming a self-nanoemulsifying drug delivery system (SNEDDS), a self-microemulsifying drug delivery system (SMEDDS) or self-emulsifying drug delivery systems (SEDDS) in an aqueous solution. Preferred fatty acids are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in a form chosen from ethyl ester and triglyceride.
