Shielded Targeting Agents, Methods, and In Vivo Diagnostic System
A system is provided which includes nanoparticle conjugates configured to bind with a tumor cell, the nanoparticle conjugate comprising a nanoparticle, at least one targeting entity bound to the nanoparticle, and at least one shielding entity that shields at the at least one targeting entity, the nanoparticle, or both; a body-mountable device mounted on an external surface of a living body and configured to detect a tumor cell binding response signal transmitted through the external surface, wherein the tumor cell binding response signal is related to binding of the nanoparticle conjugates with one or more tumor cells; and a processor configured to non-invasively detect the one or more tumor cells based on the tumor cell response signal. Nanoparticle conjugates and methods for use for treating or imaging tumor cells are also provided.
IMMUNOGENIC COMPOSITIONS, ANTIGEN SCREENING METHODS, AND METHODS OF GENERATING IMMUNE RESPONSES
An immunogenic composition is provided herein. The immunogenic compositions are used to identify and select immunogenic antigens that elicit immune responses in a subject and may be subsequently used in multi-antigen vaccine compositions against one or more diseases or conditions. According to some embodiments, the immunogenic composition may include a plurality of nucleic acid fragments or minigenes derived from a nucleic acid library, wherein each nucleic acid fragment encodes a different antigen or functional portion thereof, and wherein the different antigens or functional portions thereof are associated with one or more disease or condition. The immunogenic composition may also include a delivery medium loaded with the plurality of nucleic acid fragments and in some embodiments, the delivery medium is loaded with nucleic acid fragments in such a way that individual antigen presenting cells receive only a subset of the nucleic acids within a vaccine in order to minimize antigenic competition.
Formulation for antibody and drug conjugate thereof
Disclosed herein are surfactant free antibody and antibody-drug-conjugate (ADC) formulations for anti-AXL antibodies and ADCs, including aqueous formulations, lyophilized formulations, and reconstituted formulations, as well as related processes and uses. The formulations are particularly suitable for an anti-AXL ADC based on an auristatin or DM1 derivative or other similarly hydrophobic drugs. Some formulations comprise histidine and mannitol.
DRUG FORMULATION BASED ON PARTICULATES COMPRISING POLYSACCHARIDE-VITAMIN CONJUGATE
The present disclosure provides formulations for pharmacologically active reagents, including formulations based on particulates formed from a biodegradable polymer (e.g., a polysaccharide such as dextran) linked to a vitamin or related agent (e.g., folic acid). Hydrophobic pharmaceutically active agents (such as anti-cancer drugs, e.g., paclitaxel) are encapsulated into the polysaccharide-vitamin conjugate for the administration of paclitaxel. The active agent is in a core portion of the particulate, instead of on the surface of the particulate. Processes for making and using the particulates and compositions comprising the same are also disclosed. In particular, methods of cancer diagnosis and treatment are provided.
Method for preparing chitosan-coated magnetic nanoparticles for protein immobilization
A method for preparing chitosan-coated magnetic nanoparticles for protein immobilization includes forming ferrous ferric oxide (Fe.sub.3O.sub.4) nanoparticles by co-precipitation and coating the nanoparticles with chitosan in the presence of glutaraldehyde. The Fe.sub.3O.sub.4 nanoparticles can be coated by dispersing ferrous ferric oxide (Fe.sub.3O.sub.4) nanoparticles into a solution comprising chitosan and acetic acid, adding a surfactant, adding excess 50% glutaraldehyde solution, and washing the nanoparticles with a solvent. The chitosan coated ferric oxide (Fe.sub.3O.sub.4) nanoparticles can be used to immobilize proteins or other biomolecules.
SUSTAINED DELIVERY OF THERAPEUTIC AGENTS TO AN EYE COMPARTMENT
Compositions and methods for treating eye disorders by administering a drug delivery system into an eye compartment of the patient, wherein the drug delivery system contains a particle containing a core; a coating associated with the particle, wherein the coating is covalently or non-covalently associated with the particle and presents a hydrophilic region to the environment around the particle; and a therapeutic agent are disclosed. The eye compartment can exhibit reduced inflammation or IOP after administration of the drug delivery systems to a patient than if a drug delivery system including an uncoated particle were administered to the patient.
INTRAVASCULAR DELIVERY OF NANOPARTICLE COMPOSITIONS AND USES THEREOF
The present invention provides methods of delivering a composition comprising nanoparticles that comprise a macrolide and an albumin by directly injecting the nanoparticle composition into the blood vessel wall or the tissue surrounding the blood vessel wall. The methods can be used for inhibiting negative remodeling or vascular fibrosis in the blood vessel and are useful for treating various diseases.
