Provided are compositions and methods for reducing off-target toxicity of antibody-drug conjugates (ADCs). The compositions comprise an ADC, and an agent targeted to the drug (payload) that is delivered by or derived from the ADC. The ADC and the agent targeted to the payload may be delivered together or separately in the treatment of various conditions (such as tumors) by ADCs. Examples of agents targeted to payload include antibodies, fragments, or modifications thereof.

The present disclosure provides compositions and methods for the detection and treatment of cancer. Specifically, the compositions of the present technology include novel compounds that may be complexed with a radioisotope. Also disclosed herein are methods of the using the DOTA-haptens of the present technology in diagnostic imaging as well as pretargeted radioimmunotherapy.

The present invention concerns materials and method for delivery and internalization of an agent into a cell even in the presence of an immune response, such as antibodies or antisera or immune cells that bind to the agent. The agent can be a compound, drug, peptide, protein, nucleic acid, antigen, immunogen, or other biological molecule. In one embodiment, the agent is operatively linked to a lectin-based carrier. The present invention can be used for delivery and cellular internalization of any entity where an immune response to the entity is present or is likely to be produced or developed. The present invention also concerns methods and materials for providing for an adjuvant and carrier for vaccinations of a person or animal. The present invention also concerns a method for treating or preventing a disease or condition in a human or animal wherein the human or animal has produced or will produce an immune response against a therapeutic agent that can treat said disease or condition, the method comprising administering to the human or animal an effective amount of said therapeutic agent operatively linked to a lectin-based carrier.

The present disclosure provides compositions and methods for the treatment of cancer. Specifically, the compositions of the present technology include novel clearing agents that may be used in pretargeted radioimmunotherapy.

The present disclosure relates generally to immunoglobulin-related compositions (e.g., antibodies or antigen binding fragments thereof) that can bind to the CDS 3 protein. The antibodies of the present technology are useful in methods for detecting and treating Alzheimer's disease or a CD33-associated cancer in a subject in need thereof.

The present disclosure provides compositions and methods for the treatment of cancer. Specifically, the compositions of the present technology include novel clearing agents that may be used in pretargeted radioimmunotherapy.

The present invention provides a multivalent compound for targeted molecular imaging and/or targeted drug delivery, wherein two components or targeting molecules each interacts with one or more biomarkers on a cell.

The present invention also provides an in vitro high-throughput screening assay to determine the length of the spacer molecules. The present invention also relates to compounds/probes, kits and methods for use in targeted molecular imaging and/or targeted drug delivery.

The present disclosure provides a nano-structural protein degradation tool, use, and a preparation method thereof, wherein the nano-structural protein degradation tool comprises: one of or a combination of several of a first degradation tool, a second degradation tool, and a third degradation tool, wherein the first degradation tool is formed by linking POI recognition groups to linkers; the second degradation tool is formed by linking the POI recognition groups to nanoparticles; and the third degradation tool is formed by linking the POI recognition groups to the nanoparticles through the linkers. The present disclosure further provides a lipid-based protein degradation tool, use, and a preparation method thereof, wherein the lipid-based protein degradation tool comprises: POI recognition groups, and lipid hybrid substances linked to the POI recognition groups.

The present invention provides a method of targeted molecular imaging and/or targeted drug delivery, wherein two components or probes each interacts with one or more biomarkers on a cell and separately interact with each other to form a stable bond, such as a stable covalent bond. In certain non-limiting embodiments, at least one of the probes is photo-triggered to allow for bonding with at least one second probe. In certain non-limiting embodiments, the cell is a tumor or cancer cell. The present invention also relates to compounds, probes, and kits for use in targeted molecular imaging and/or targeted drug delivery.
