20220118416 · 2022-04-21 ·

Novel composite materials and their methods of preparation comprising a crosslinked biodegradable polymer and non-crosslinked biodegradable polymers are disclosed. The composite materials can be formed into injectable compositions comprising composite microparticles or microspheres. The non-crosslinked biodegradable polymer in the composite material is synthesized or precipitated in situ inside the particle. The non-crosslinked biodegradable polymer in the composite may be liquid, low melting solid or polymer with thermosensitive or pH sensitive gelation properties. Also disclosed are injectable compositions comprising microparticles or microspheres for controlled drug delivery wherein such particles are delivered using organic solvents. Also disclosed are methods and compositions for making two or more layered particles for medical and industrial use.

20220016199 · 2022-01-20 ·

The invention provides a composition and pharmaceutical formulation including a peptide immobilized in a hydro gel. Compositions and formulations of the invention are useful in reducing the size, severity or duration of a wound, ameliorating of one or more symptoms associated with a wound without necessarily curing the wound, or lessening in the growth or severity of a wound. Compositions and formulations of the invention are particularly useful in the treatment of a wound associated with diabetes, such as a diabetic ulcer.

PEPTIDE HYDROGELS FOR DELIVERY OF IMMUNOSUPPRESSIVE DRUGS AND USES THEREOF
20220016250 · 2022-01-20 ·

Compositions that include a cationic peptide hydrogel and an immunosuppressive small molecule drug are described. The small molecule drug is crystallized and dispersed in the peptide hydrogel to allow for slow release of the drug. Methods of inhibiting allograft rejection and treating autoimmune-mediated organ damage by local administration of the peptide hydrogel compositions are described.

Hydrogels with biodegradable crosslinking

Hydrogels that degrade under appropriate conditions of pH and temperature by virtue of crosslinking compounds that cleave through an elimination reaction are described. The hydrogels may be used for delivery of various agents, such as pharmaceuticals.

DENDRIMER-BIOADHESIVE POLYMER HYDROGEL NANOGLUE AND USE THEREOF

A nanoglue is formed with one or more bioadhesive polymers, one or more dendrimers, and optionally one or more therapeutic, prophylactic, or diagnostic agents. The bioadhesive polymers and dendrimers are modified with functional groups to permit crosslinking upon one or more stimuli, e.g., ultraviolet irradiation, and form hydrogel in situ at tissue sites. In the repair of corneal wounds, the nanoglue leads to improved rate of healing with less scarring and less inflammation, compared to non-treated cornea or ones treated with sutures. Therapeutic agents can be covalently conjugated to the precursor components and be delivered to specific eye compartments, providing a more efficacious treatment formulation of ocular disorders than delivering drugs in their free forms. Methods of making and using the hydrogel and hydrogel precursor compositions are also provided.

MACROMOLECULAR PRODRUG-BASED THERMOSENSITIVE INJECTABLE GEL AS A NOVEL DRUG DELIVERY PLATFORM

This application discloses prodrug-based thermosensitive gel (“ProGel”) comprised of conjugates of dmg molecules with water-soluble polymeric carriers, which are capable of controlled release of the dmg molecules into the tissue of a subject. Use of the ProGel-Drug conjugates for treatment of various diseases or disorders and methods of preparing them are also disclosed.

Antiseptic polymer and synthesis thereof
11219639 · 2022-01-11 · ·

According to the present invention there is provided a polymer comprising at least one antiseptic/analgesic/anti-inflammatory monomeric unit in conjunction with at least three further monomeric units, said three further monomeric units eliciting properties selected from the group consisting of: temperature activation, water solubility, mechanical strength, protein/polysaccharide bonding capacity, and combinations thereof. In particular, disclosed herein is a polymer, wherein: the water-soluble monomeric unit is a hydrophilic ethylene glycol (OEGMA) moiety; the mechanical strength-conferring monomeric unit is polylactide-co-2-hydroxy-ethyl-methyl acrylate (PLA/HEMA); the protein-reactive monomeric unit is an N-acryloxysuccinimide (NAS) moiety; and the thermosetting monomeric unit is an N-isopropyl acrylamide (NIPAAm) moiety. The anti-septic/analgesic/anti-inflammatory monomeric unit comprises a methacrylic ester derivative of salicylic acid (5-HMA or 4-HMA, or a combination thereof).
