The present invention concerns a polymeric material for the production of a non-viral nanoparticle. The polymeric material comprises (i) a hydrophilic linear polymer having a first end and a second end, (iii) a cross-linkable cationic polymer covalently bonded to the first end of the hydrophilic linear polymer, and (iii) at least one targeting/penetrating peptide covalently associated to the second end of the hydrophilic linear polymer. Also disclosed herein are nanoparticles produced with these polymeric material, processes for making the polymeric material and the nanoparticles as well as use of the nanoparticles.

The present invention relates to a nanoliposome-microbubble conjugate, in which a complex of a Cas9 protein, a guide RNA inhibiting SRD5A2 gene expression and a cationic polymer is encapsulated in a nanoliposome, and to a composition for the amelioration or treatment of hair loss containing the same. Currently, drugs used for the treatment of hair loss cause serious side effects such as loss of libido or erectile dysfunction, and hair loss progresses again when drug treatment is stopped. However, when the nanoliposome-microbubble conjugate of the present invention is used, the expression of SRD5A2 inducing hair loss can be fundamentally suppressed, and the treatment of male hair loss can be performed very effectively.

Provided herein are encapsulated liposomes comprising a lipid bilayer, a first polyethylene glycol (PEG) corona, a targeting molecule and a second PEG corona. The second, encapsulating PEG corona can be reversibly linked to the first PEG corona. Also provided are pharmaceutical compositions comprising the encapsulated liposomes and methods of treating a subject with a disease characterized by production of reactive oxygen species (ROS) with the compositions. Also provided are methods of making the encapsulated liposomes disclosed herein.

This invention discloses a pharmaceutical composition for treating tumors wherein said pharmaceutical comprises a proinflammatory cytokine such as Tumor Necrosis Factor alpha (TNF-a) combined with one or more small molecule cancer drugs within the same liposome. The liposomes are sized to be below 250 nm in diameter to enable them to localize within the tumor due to the Enhanced Permeability and Retention (EPR) effect. This liposomal formulation will ensure that the proinflammatory cytokine and the cancer drug are localized together within the tumor and with less exposure to normal tissues. This invention also discloses that the safety and efficacy of said proinflammatory cytokine/drug liposomes could be further enhanced by coating the exterior of said liposomes with a tumor targeting agent.

The present disclosure relates to photo-immunoconjugate formulations comprising a nanoparticle carrier comprising first and second therapeutic agents coupled to the nanoparticle carrier, and a photosensitizer molecule coupled to the first therapeutic agent or the nanoparticle carrier, and methods of treating cancer via administration of the photo-immunoconjugate formulations.

The disclosure relates generally to polyglutamated alpha tetrahydrofolate compositions, including delivery vehicles such as liposomes containing the polyglutamated alpha tetrahydrofolate, and methods of making and using the polyglutamated alpha tetrahydrofolate compositions to treat hyperproliferative disorders (e.g., cancer) and disorders of the immune system (e.g., inflammation and autoimmune diseases such as rheumatoid arthritis). The disclosed compositions also have uses in combination therapy with one or more therapeutic agents to enhance the effectiveness or to reduce the toxicities associated with the therapeutic agent(s).

The disclosure relates generally to gamma polyglutamated pralatrexate compositions, including delivery vehicles such as liposomes containing the gamma polyglutamated pralatrexate, and methods of making and using the gamma polyglutamated pralatrexate compositions to treat hyperproliferative disorders (e.g., cancer) and disorders of the immune system (e.g., inflammation and autoimmune diseases such as rheumatoid arthritis).

A fusogenic liposome comprising a detectable agent and optionally a cytotoxic drug in its internal aqueous compartment or bound to the liposome membrane is provided, wherein said fusogenic liposome comprises a lipid bilayer comprising a plurality of lipid molecules having 14 to 24 carbon atoms, and at least one of said lipid molecules further comprises a cationic group, a cationic natural or synthetic polymer, a cationic amino sugar, a cationic polyamino acid or an amphiphilic cancer-cell binding peptide; and at least one of said lipid molecules further comprises a stabilizing moiety selected from the group consisting of polyethylene glycol (PEG), polypropylene glycol, polyvinyl alcohol, polyvinylpyrrolidone (PVP), dextran, a polyamino acid, methyl-polyoxazoline, polyglycerol, poly(acryloyl morpholine), and polyacrylamide. Methods utilizing these liposomes in treatment of cancer are further provided.

The disclosure relates generally to alpha polyglutamated lometrexol, formulations containing liposomes filled with alpha polyglutamated lometrexol, methods of making the alpha polyglutamated lometrexol and liposome containing formulations, and methods of using polyglutamated alpha polyglutamated lometrexol and liposome containing formulations to treat hyperproliferative disorders (e.g., cancer) and disorders of the immune system (e.g., an autoimmune disease such as rheumatoid arthritis).

This disclosure relates to novel ligand-drug particles comprising at least one ligand specific for one or more cell surface receptor molecules for targeting the ligand-drug particles to a target cell. This disclosure also relates to pharmaceutical compositions comprising the particles herein and systems and methods for determining the ligand valency of the particles.
