It is an object of the present invention to provide a conjugate of a biotin-modified dimer and a phthalocyanine dye, which is used in photoimmunotherapy. The present invention provides a conjugate of a compound represented by the following formula (1) or a salt thereof and a phthalocyanine dye:

##STR00001##

wherein the meaning of each of symbols is as defined in the specification.

Disclosed are monoclonal antibodies that bind specifically to macrophage stimulating protein receptor (or RON—Recepteur d' Origine Nantais). Also provided are the chimeric antigen receptors, bispecific antibodies, bivalent antibodies and biTE thereof, as well as pharmaceutical compositions and uses of said antibodies for the treatment of cancer and fibrosis and an ex vivo method of evaluating the status of a cancer patient using said antibodies. In particular, two monoclonal antibodies, 7G8 and 6D4, demonstrating good therapeutic efficacy in inhibiting tumour growth in human xenograft mice models and sensitivity in human xenograft mouse tumour imaging models are provided.

Methods and compositions are described herein for covalently linking an antibody to a molecular payload. Compositions are described herein containing an antibody covalently linked to a molecular payload.

Disclosed in the present invention are an antibody targeting IL-5, a preparation method therefor and use thereof. In particular, disclosed in the present invention is a novel murine-derived or chimeric monoclonal antibody targeting IL-5. Also disclosed in the present invention is a method for preparing said monoclonal antibody. The monoclonal antibody of the present invention is capable of binding IL-5 antigen with high specificity, has high affinity and can well alleviate a series of asthma symptoms caused by IL-5, thereby achieving the effect of treating asthma.

Conjugate (KTAC) compounds that include a peptidic kappa opioid receptor agonist linked through a protease-sensitive linker and/or acid-sensitive linker to an antibody molecule are provided. The linker may include spacer regions on either side of the protease sensitive cleavage site. The antibody can be a monoclonal antibody such as a therapeutic monoclonal antibody. The KTAC compounds may be incorporated into pharmaceutical compositions useful for the treatment of diseases and conditions, particularly those that include an inflammatory component.

Specific binding members, particularly antibodies and fragments thereof, which bind to transforming growth factor beta 3 (TGF-β3) are provided, particularly recognizing human and mouse TGF-β3, particularly antibodies and fragments that do not recognize or bind TGF-β1 or TGF-β2. Particular antibodies are provided which specifically recognize and neutralize TGF-β3. These antibodies are useful in the diagnosis and treatment of conditions associated with activated or elevated TGF-β3, including cancer, and for modulating immune cells and immune response, including immune response to cancer or cancer antigens. The anti-TGF-β3 antibodies, variable regions or CDR domain sequences thereof, and fragments thereof may also be used in therapy in combination with chemotherapeutics, immune modulators, or anti-cancer agents and/or with other antibodies or fragments thereof. Antibodies of this type are exemplified by the novel antibodies hereof, including antibody MTGF-β3-9, MTGF-β3-12, MTGF-β3-16, MTGF-β3-17 and MTGF-β3-19, whose sequences are provided herein.

This invention relates to anti-CD70 antibodies and antibody drug conjugates comprising at least one non-naturally-encoded amino acid. Disclosed herein are aCD70 antibodies with one or more non-naturally encoded amino acids and further disclosed are antibody drug conjugates wherein the aCD70 antibodies of the invention are conjugated to one or more toxins. Further disclosed are methods for using such non-natural amino acid antibody drug conjugates, including therapeutic, diagnostic, and other biotechnology uses.

A conjugate may comprise a first component capable of binding to a therapeutic target in the eye, one or more second component(s) capable of binding to hyaluronan, and one or more third component(s) comprising hyaluronan, wherein each second component is covalently bound to the first component and non-covalently bound to a third component, a composition comprising the conjugate for use as a medicament or for use in the treatment of an eye disease and a method of treating an eye disease in a subject. Additionally, a therapeutic molecule targeted to a tissue in a patient may comprises a hyaluronic acid binding moiety and a therapeutically active agent, wherein the hyaluronic acid binding moiety comprises at least two link domains of Versican.

This invention relates to antibody-albumin nanoparticle complexes comprising albumin, an antibody with binding specificity for a cancer antigen (e.g. panitumumab), and paclitaxel, wherein the nanoparticle complex has been pre-formed in vitro such that the nanoparticle complex has antigen-binding specificity (e.g. EGFR binding specificity), for the purpose of providing cancer (e.g. EGFR-related cancer) treatments in a subject in need thereof.

The disclosure features fusion proteins that are conditionally active variants of a cytokine of interest. In one aspect, the full-length polypeptides of the invention have reduced or minimal cytokine-receptor activating activity even though they contain a functional cytokine polypeptide. Upon activation, e.g., by cleavage of a linker that joins a blocking moiety, e.g. a steric blocking polypeptide, in sequence to the active cytokine, the cytokine can bind its receptor and effect signaling. Typically, the fusion proteins further comprise an in vivo half-life extension element, which may be cleaved from the cytokine in the tumor microenvironment.
