Cyclooctene conjugates of therapeutic or diagnostic agents have improved aqueous solubility and can release the agents upon contact with a tetrazine-containing biomaterial. The cyclooctene conjugates provide site-selective delivery of agents at the location of the tetrazine-containing biomaterial in a subject. The compositions and methods have applications in the treatment of various diseases or conditions including cancer, tumor growths, and bacterial infections.

The present invention relates to a method for crosslinking hyaluronic acid, a method for preparing an injectable hydrogel, the hydrogel thus obtained and its use.

The present invention provides a nanoparticle comprising: a core comprising a metal and/or a semiconductor; and a plurality of ligands covalently linked to the core, wherein said ligands comprise: (i) at least one dilution ligand comprising a carbohydrate, glutathione or a polyethyleneglycol moiety; and (ii) a ligand of the formula MTX-L-, wherein MTX-L-represents methotrexate coupled to said core via a linker L. Also provided are pharmaceutical compositions of the nanoparticle, including gel formulations, and medical uses of the nanoparticle and pharmaceutical compositions, including for the treatment of an inflammatory or autoimmune disorder, such as psoriasis.

The present invention refers to compositions comprising recombinant biopolymers made of combinations of monomers of the type “Elastin-like recombinamers” (ELR), monomers comprising the “silk” sequence and/or monomers comprising the HLF sequence that belongs to a natural class of proteins named zippers. Said compositions are useful as bio-ink for 3D printing. Furthermore, the present invention also refers to methods for obtaining the composition of the invention, as well as the 3D biomaterial and to the different uses of the composition and the obtained biomaterial.

The invention provides antibodies, antibody drug conjugates, antibody-based fragments or antibody fragments (antigen-binding fragments), as well as antibody drug conjugates (ADCs) and chimeric antigen receptors (CARs), that specifically recognize human ROR1 and related compositions. Also provided in the invention are methods of using such antibodies in various diagnostic and therapeutic applications.

Compositions for delivering one or more active substances, or for repairing a bone, and methods of making and using the same, are described.

The present invention relates to conjugates of an electron-donating heteroaromatic nitrogen or tertiary amine comprising drugs and pharmaceutically acceptable salts thereof, pharmaceutical compositions comprising said conjugates and the use of said conjugates as medicaments.

The present invention relates to conjugates of π-electron-pair-donating heteroaromatic nitrogen-comprising drugs and pharmaceutically acceptable salts thereof, pharmaceutical compositions comprising said conjugates and the use of said conjugates as medicaments.

The present invention relates to an anti-CTLA4 conjugate or a pharmaceutically acceptable salt thereof, wherein said conjugate comprises a plurality of anti-CTLA4 moieties -D covalently conjugated via at least one moiety -L.sup.1-L.sup.2- to a polymeric moiety Z, wherein -L.sup.1- is covalently and reversibly conjugated to -D and -L.sup.2- is covalently conjugated to Z and wherein -L.sup.1- is a linker moiety and -L.sup.2- is a chemical bond or a spacer moiety; and related aspects.

A tissue sealant for use in surgical and medical procedures for sealing the tissues of a living mammal is provided. The tissue sealant comprises a hydrogel which is formed by gelation of a premix disposed on the tissue to be sealed. The premix comprises alkylated chitosan or a gelatin, and a polybasic carboxylic acid or an oxidized polysaccharide, in an aqueous medium. The premix can also include a dehydrating reagent, a carboxyl activating reagent, or both. A specific use of the tissue sealant is in the repair of the dura mater after brain surgery to prevent leakage of cerebrospinal fluid. The tissue sealant may include a therapeutic or protective agent such as an antibiotic or an anti-inflammatory drug.
