`Nasal and Ophthalmic Delivery of Aqueous Corticosteroid
`
`Solutions
`
`FIELD OF THE INVENTION
`
`The present invention is directed to methods of treating nasal and/or ophthalmic
`
`diseases, symptoms, or disorders that are therapeutically responsive to corticosteroid
`
`therapy by delivering aqueous solution formulations comprising a corticosteroid to nasal
`
`5
`
`and ophthalmic tissues. The invention is also directed to methods, systems, devices, and
`
`compositions for delivering aqueous solution formulations comprising a corticosteroid and
`
`an antihistamine to nasal and ophthalmic tissues.
`
`BACKGROUND OF THE INVENTION
`
`The nasal administration of drugs allows for their deposition to the nose, sinuses,
`
`10
`
`and other nasal cavities. Intranasal administration of drugs such as corticosteroids and
`
`antihistamines may be used to treat nasal symptoms including seasonal allergic rhinitis,
`
`perennial allergic rhinitis, perennial non-allergic rhinitis, nasal polyps, as well as
`
`prevention of post surgical polyps, chronic sinusitis, recurrent sinusitis, asthma, grass
`
`pollen rhinitis, hay fever, snoring, cluster headache, and other diseases and disorders.
`
`15
`
`The ophthalmic administration of drugs allows for their deposition to the eye,
`
`including the ocular mucosa, eye surface, cornea, conjuctiva, sclera, and posterior eye
`
`parts such as the retina, choroid, and vitreous and optic nerves, as well as tissues
`
`surrounding the eye. Ophthalmic administration of drugs such as corticosteroids and
`
`antihistamines may be used
`
`to
`
`treat ocular symptoms
`
`including conjunctivitis,
`
`20
`
`inflammation of tissue(s) in the eye, dry eye, filamentary keratitis, delayed tear clearance,
`
`pain, keratoconjunctival dryness, keratoconjunctivitis sicca, lesions/tumors of the eye,
`
`infectious processes of the eye, bacterial infections, viral infections, glaucoma, uveitis,
`
`diabetic retinopathy, eye trauma, blepharitis, blepharoconjunctivitis, and other diseases or
`
`disorders.

`
`DETAILED DESCRIPTION OF THE INVENTION
`
`The present invention is directed to methods of treating nasal and/or ophthalmic
`
`diseases, symptoms, or disorders that are therapeutically responsive to corticosteroid
`
`therapy by delivering aqueous solution formulations comprising a corticosteroid to nasal
`
`and ophthalmic tissues. The invention is also directed to methods, systems, devices, and
`
`30
`
`compositions for delivering aqueous solution formulations comprising a corticosteroid and
`
`an antihistamine to nasal and ophthalmic tissues. The systems of the invention comprise
`
`an administration device, and a composition of the invention. The composition of the
`
`Page 12
`
`
`
`WO 2009/003199
`
`PCT /US2008/068872
`
`- 12 -
`
`invention 1s a corticosteroid solution compnsmg a corticosteroid and SAE-CD. The
`
`composition can be a nasal or non-nasal composition or an ophthalmic composition. In
`
`some embodiments, a non-nasal composition excludes an inhalable composition for
`
`pulmonary delivery.
`
`5
`
`By including SAE-CD in a liquid composition containing corticosteroid, the
`
`corticosteroid is dissolved. The corticosteroid exhibits greater stability in the presence of
`
`SAE-CD than it does in its absence. When a second active agent is present, the second
`
`active agent can also exhibit greater stability in the presence of SAE-CD than it does in its
`
`absence.
`
`10
`
`The methods, systems, devices, and compositions of the invention can provide an
`
`enhanced pharmacokinetic profile over a
`
`suspens10n
`
`formulation
`
`compnsmg
`
`approximately the same amount of a therapeutic agent and delivered under substantially
`
`the same conditions. The therapeutic agent is a corticosteroid alone or a corticosteroid
`
`combined with one or more additional therapeutic agents. As such, one or more
`
`15
`
`therapeutic agents in the methods, systems, devices, and compositions of the invention can
`
`demonstrate an enhanced pharmacokinetic profile when compared with the same
`
`therapeutic agent or agents
`
`in a suspension formulation.
`
`The
`
`term "enhanced
`
`pharmacokinetic profile" is taken to mean a higher AUC (e.g. AUC1ast or AUCco-700)) per
`
`µg of therapeutic agent delivered or administered, a higher Cmax per µg of therapeutic
`
`20
`
`agent delivered or administered, increased bioavailability, absorption or distribution of the
`
`therapeutic agent at the site of delivery, a shorter Tmax, or a longer Tmax. The methods,
`
`systems, devices, and compositions of the invention can also provide other enhancements
`
`over a suspension-based formulation, such as enhanced drug delivery, increased rate of
`
`drug administration, reduced treatment time, reduced toxicity,
`
`improved stability,
`
`25
`
`enhanced bioabsorption, increased output rate, increased total output, reduced side effects
`
`associated with the therapeutic agent, increased nasal cavity deposition, increased
`
`paranasal sinus cavity deposition, increased ocular deposition, improved quality of life,
`
`reduced mucociliary clearance, reduced ocular clearance, and/or improved patient
`
`compliance.
`
`30
`
`Alternatively, the methods, systems, devices, and compositions of the invention
`
`provide substantially the same pharmacokinetic profile or an enhanced pharmacokinetic
`
`profile over a suspension formulation comprising a higher amount of therapeutic agent and
`
`delivered under substantially the same conditions.
`
`The therapeutic agent in the
`
`Page 13
`
`
`
`WO 2009/003199
`
`PCT /US2008/068872
`
`- 13 -
`
`formulation can be present at a dose that is less than about 80%, less than about 70%, less
`
`than about 60% less than about 50%, less than about 40%, less than about 20%, or less
`
`than about 10% of that in the suspension.
`
`The amount and/or concentration of SAE-CD in the composition can be varied as
`
`5
`
`needed or as described herein to provide a composition that possesses a desired physical
`
`property, provide therapeutic effectiveness in subjects to which the composition is
`
`administered, and/or achieve a desired performance in an administration device. SAE-CD
`
`can be present in an amount sufficient to solubilize and/or stabilize the therapeutic agent
`
`when the SAE-CD and therapeutic agent are placed in the aqueous carrier. The aqueous
`
`10
`
`carrier can be present in an amount sufficient to aid in dissolution of the therapeutic agent
`
`and form a solution of sufficient volume and sufficiently low viscosity to permit
`
`administ
