The invention relates to a pharmaceutical composition comprising the combination of (i) at least one biocompatible nanoparticle, said biocompatible nanoparticle comprising at least one oligomer of albumin (n≧2) or consisting in an oligomer of albumin, and of (ii) at least one compound of interest, typically at least one pharmaceutical compound, to be administered to a subject in need of such at least one compound of interest, wherein the at least one nanoparticle potentiates the at least one compound of interest efficiency. The longest dimension of the biocompatible nanoparticle is typically between about 4 and about 500 nm. The invention also relates to such a composition for use for administering the at least one compound of interest in a subject in need thereof, wherein the at least one biocompatible nanoparticle and the at least one compound of interest are to be administered in said subject sequentially, typically between more than 5 minutes and about 72 hours one from each other.

The invention pertains to a therapeutic, prophylactic or diagnostic method comprising, administering a pharmaceutical compound followed by administering a biocompatible nanoparticle comprising an oligomer of albumin, wherein the longest or largest dimension of the nanoparticle is between about 4 nm and about 500 nm. In preferred embodiments, administering the biocompatible nanoparticles is performed between more than 5 minutes and about 72 hours after administering the pharmaceutical compound. In particular embodiments, the pharmaceutical compound is a pharmaceutical antibody, such as a monoclonal antibody, a drug conjugated antibody, an engineered antibody and a multispecific antibody. According to the methods of the invention, administering the biocompatible nanoparticle comprising oligomers of albumin after administering the pharmaceutical compound maintains or increases the therapeutic benefit and reduces toxicity of the pharmaceutical compound when compared to the therapeutic benefit and toxicity induced by administering the pharmaceutical compound alone.

Drug delivery systems comprising binding partners conjugated to a nanoparticle encapsulating a therapeutic agent formulated for oral administration, and methods of delivering therapeutic agents across the gastrointestinal epithelium.

Self-assembled protein nanoparticle (SAPN) are excellent antigen due to its ability to simultaneously present multiple epitopes to B cell and generate much stronger B cell receptor signaling than single epitope. Most of the SAPN are derived from capsid protein of virus or bacterial phage, which suffer from low particle stability, existing antibody against capsid protein and structural intolerant to peptide insertion. In this invention, we have created a SAPN using non-viral protein that is both thermal stable and tolerate to target peptide insertions. The assembling subunit of this SAPN is a fusion protein between two components: first, a polymerization module composed of an amphipathic helical peptide modified from M2 protein of type A influenza virus and second, a target peptide presentation module that composed of a superfolder green fluorescent protein (sfGFP) with a peptide insertion site on a specific loop of sfGFP. This particle is able to incorporate target peptide through genetic recombination and presented the target protein in the surface of nanoparticle to stimulate the production of high affinity antibody against target peptide without using adjuvant.

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 TOP 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.

The invention provides a macromolecule-supported compound of formula (I) or (II). Macromolecule-supported compounds of the invention, comprising macromolecular support linked to one or more TLR agonists, are recognized by TLRs (e.g., TLR7 and/or TLR8) with high affinity providing utility in therapeutics, diagnostics, and chemical assays. The invention further provides compositions comprising and methods of treating cancer with the macromolecule-supported compounds.

The present invention relates to compositions and methods for imaging and treating various diseases and disorders, including cancers. The composition of the invention can include a plurality of biodegradable micro-beads, each embedding a plurality of nano-beads, further including a polymer, a radionuclide, a radionuclide chelator, a radioligand, a chemotherapeutic agent, and a cell-penetrating peptide. Upon injection into a blood vessel supplying a cancer tumor, the micro-beads lodge into the tumor and degrade, releasing the nano-beads with a therapeutic or diagnostic agent. The compositions and methods of the invention provide a more homogeneous and deeper distribution of radiation or chemotherapeutic agents throughout the target tumor. The micro-beads provide a local, sustained, and controlled delivery nano-beads including therapeutic or diagnostic agents.

Compositions and methods for inducing a protective mucosal immunity against an antigen in a subject include the step of administering to a mucosal tissue an effective amount of a vaccine composition including the antigen or polynucleotide encoding an antigen associated or encapsulated within carriers such as poly(amine-co-ester) polymers in the form of particles (e.g., solid nanoparticles formed of PACE) or PACE copolymers and/or blends. Typically, the subject has previously been exposed to the antigen, for example, by administering to the same subject via a systemic or mucosal route of administration a priming antigen. In some embodiments, the polynucleotides-based vaccines are messenger RNAs encoding a viral antigen such as a coronavirus spike protein sequence, or a portion thereof. In preferred embodiments, the vaccine composition is administered intranasally.

Compositions comprising clathrin nanoparticles and methods for treating neurological-associated disorders.

Compositions for delivering a drug to a subject having: a plurality of self-assembled supramolecular nanoparticles (SMNPs), each of the plurality of self-assembled supramolecular nanoparticles (SMNPs) having: a plurality of binding components, each having a plurality of binding regions; a plurality of cores that are suitable to at least provide some mechanical structure to the plurality of self-assembled supramolecular nanoparticles (SMNPs), the plurality of cores comprising at least one core binding element adapted to bind to the binding regions to form a first inclusion complex; a plurality of terminating components, each having a single terminating binding element that binds to remaining binding regions of one of said plurality of binding components by forming a second inclusion complex; the drug; and a reporter agent, and methods of use thereof.
