Dendrimer-based compositions and methods are provided, that are useful for administering pharmaceutical compositions to target cells and tissues for treatment of ocular diseases including macular degeneration, diabetic retinopathy, and retinitis pigmentosa.

Provided herein is a drug delivery device and composition, such as a particle, comprising conditioned medium. Also provided herein is a method of preparing polymeric particles for release of conditioned medium. Further, a tissue growth scaffold comprising particles for release of conditioned medium is provided.

The present application provides a microsphere in which a main agent is uniformly dispersed in a polymer matrix, wherein an average volume-based particle diameter of the microsphere is 1 μm or more and 150 μm or less, and a variation coefficient of area ratios in four regions is 0.35 or less, wherein the area ratios in four regions are calculated by (s/A)×100 (%) wherein the four regions are prepared by preparing a cross section observation sample obtained by cutting the microsphere; observing the cross section observation sample with an electron microscope at a magnification capable of confirming the main agent in the microsphere or a higher magnification; and dividing the electron microscope observation image into four regions; and A is an area of a respective divided region, and s is a sum of cross section areas of the main agent included in the respective divided region. The microsphere of the present invention can appropriately control the initial release amount of the main agent and its release rate during a subsequent release period, and can continuously release the main agent for a predetermined period of time.

The present invention provides compositions and methods for the treatment of diseases and disorders. In some embodiments the compositions and methods involve administration of a microparticle, or composition thereof that includes an antifibrotic.

The invention generally relates to compositions and methods for preventing sternal wound infections, such as mediastinitis. In certain embodiments, the invention provides an antimicrobial composition including at least one bioresorbable polymer, such as a tyrosine-derived polyesteramide, and at least one antimicrobial agent, in which the composition is adapted to be topically applied to an esophageal perforation in a subject or a median sternotomy incision site in the subject, and in which the at least one antimicrobial agent is present in an amount effective to inhibit development of mediastinitis in the subject.

The present disclosure relates to compositions and methods for the regeneration and/or restoration of hair cells utilizing a composition or an agent that decreases expression of a gene in a tissue of the inner ear and a second agent.

The invention provides compositions comprising microparticles wherein the microparticles comprise at least one adenosine 2a receptor antagonist (A2ARA), at least one pharmaceutically acceptable polymer and at least one pharmaceutically acceptable negatively charged agent wherein the microparticles optionally have a highly negative zeta potential of less than about −40 mV. The invention also provides pharmaceutical compositions of the microparticles of the invention and methods of using the compositions of the invention to enhance an immune response in a patient in need thereof and as anti-cancer immunotherapy.

Compositions containing a protease inhibitor for treating viral infections and methods for treating a patient before, during, or after exposure to an infectious agent by administering such compositions are described herein.

Described here are various compositions for the delivery active agents, e.g., antifungal agents. The compositions may be beneficial due to the particular release kinetics associated with them. Various locations and methods for placement of the compositions into the tissues of the nail unit, as well as tissues surrounding the nail milt are also described.

Provided is a method for treating and reducing the recurrence of genital tract infections such as gonococcal infections. The method comprises local application of IL-12 incorporated in polymeric microspheres. The invention relates to compositions comprising IL-12 and methods for using such compositions for treatment of genital tract infections. Infections that can be treated by the present method include those that are caused by N. gonorrhoeae, C. trachomatis or both.
