An injectable formulation of therapeutic agent may comprise the therapeutic agent and a stabilizer such that a substantial portion of the stabilizer remains in the therapeutic device to stabilize the therapeutic agent when the therapeutic agent is released from the therapeutic device. The injectable formulation may comprise one or more of binding agent particles or erodible material particles, such that the formulation can be injected into the therapeutic device. The binding agent particles can bind reversibly to the therapeutic agent so as to modulate release of the therapeutic agent, and the erodible material particles can generate protons of an acid so as to increase stability of the therapeutic agent and may modulate release of the therapeutic agent. The therapeutic agent can be combined with one or more of the stabilizer, the binding agent particles or the erodible particles to increase stability of the therapeutic agent and may modulate release.

Provided are methods and compositions for protecting treating ischemic events in the retina. The methods include administering a MANF family protein (e.g., MANF, CDNF, or fragments thereof) to a subject and performing another treatment to resolve the blockage underlying the ischemic event. The methods also include administering a MANF family protein to extend the therapeutic window for treatment of a retinal artery occlusion.

Disclosed herein is an ophthalmic formulation comprising a compound of formula (I) wherein le is a linear or branched C.sub.9-C.sub.33 alkyl or a linear or branched C.sub.9-C.sub.33 alkenyl with 1 to 4 double bonds; R.sup.2 is a linear or branched C.sub.9-C.sub.19 alkyl or a linear or branched C.sub.9-C.sub.19 alkenyl with 1 to 4 double bonds; and an ophthalmologically acceptable carrier.

A polymeric compound is disclosed herein, having the general formula I: ##STR00001##
wherein m, n, X, Y, Z and L are as defined herein. Further disclosed herein are lipid bilayers comprising at least one bilayer-forming lipid and the aforementioned polymeric compound, and liposomes comprising such a bilayer, as well as methods, uses and compositions utilizing such bilayers and/or liposomes for reducing a friction coefficient of a surface and/or for inhibiting biofilm formation.

Polymeric eye inserts are provided that may be dissolvable when placed in the cul-de-sac of the eye. These inserts may contain one or more mucoadhesive polymers polymers, a biodegradable polymer as well as softener/plasticizer so that, when inserted into the eye, they may absorb tears, and dissolve and slowly release lubricant into the tear film to lubricate and protect the ocular surface for an extended duration of time. The biodegradable polymer containing eye insert may increase dissolution time on the ocular surface for longer lasting relief, may reduce dosing frequency and patient burden typically associated with topical drop usage. These polymeric eye inserts also may include one or more pharmaceutically active agents.

Described herein are methods and devices for the long term treatment of ophthalmic disorders. Also disclosed are encapsulated cell therapy (ECT) devices that secrete a biologically active molecule and methods for using the same for the treatment of various kinds of ophthalmic disorders, including retinitis pigmentosa, geographic atrophy (dry age-related macular degeneration), glaucoma and/or macular telangiectasia.

A lacrimal drug delivery device includes a reservoir configured to hold a drug. The reservoir is moveable between a relaxed state and an expanded state. A connector is fluidly coupled to the reservoir and a lumen is formed in the connector wherein the drug is configured to flow from the reservoir to an delivery site through the lumen. A hydrogel is within the lumen and configured to absorb the drug from the reservoir and deliver the drug from the lumen at the delivery site. The hydrogel includes a first section which absorbs the drug at a first rate of absorption. A delivery guide is detachably coupled to the reservoir to deliver the reservoir into a lacrimal sac of a patient.

Disclosed are biodegradable nanocarriers that have a net positive surface charge and zeta potential between about +2 to about +20 mV. The positive surface charge of the nanocarriers is provided by peptides that are covalently attached to the surface of the nanocarriers. The nanocarriers may comprise a drug and may be administered for localized and sustained delivery of the drug.

A medical device may comprise a body including a mixture of polyvinylpyrrolidone (“PVP”) and mitomycin. The medical device may be in any size or shape such that the medical device may be inserted into living tissue, including, but not limited to, a lacrimal punctal plug and a stent. The mixture of PVP and mitomycin may be coated on a portion of the medical device, contained within a cavity on the medical device, disposed on the surface of the medical device or configured as part of the medical device such that the mixture of PVP and mitomycin can be delivered to tissue.

The invention contemplates a copolymer which is a graft or block copolymer useful to change wettability and surface characteristics of biological surfaces. Methods for use of these formulations and coatings to change wettability and sterically stabilize, and lubricate biological surfaces in a subject, for example, in the treatment of dry eye syndrome, and to prevent adherence of unwanted proteins, for example in the treatment of contact lens intolerance, are provided.
