`
`BACKGROUNDOF THE INVENTION
`
`The present invention relates to methods of providing
`desired therapeutic effects to humans or animals using com-
`positions including cyclosporin components. More particu-
`larly, the invention relates to methods including administer-
`ing to an eye of a humanor animala therapeutically effective
`amount of a cyclosporin component to provide a desired
`therapeutic effect, preferably a desired ophthalmic or ocular
`therapeutic effect.
`The use of cyclosporin-A and cyclosporin A derivatives to
`treat ophthalmic conditions has been the subject of various
`patents, for example Dinget al U.S. Pat. No. 5,474,979; Garst
`USS. Pat. No. 6,254,860; and Garst U.S. Pat. No. 6,350,442,
`this disclosure of each of whichis incorporatedin its entirely
`herein by reference.In addition, cyclosporin A compositions
`used in treating ophthalmic conditions is the subject of a
`number of publications. Such publicationsinclude,
`for
`example, “Blood concentrationsoficyclosporin a ‘during
`long-term treatment with!(cyclosporit*Spimaimie emul-
`sions in patients with mosPAETOSevERsdry eye disease,”
`Small etal, J Ocul Pharmacol Ther, 2002 October, 18(5):411-
`8; “Distribution of cyclosporin A in ocular tissues after topi-
`cal administration to albino rabbits and beagle dogs,”
`Acheamponget al, Curr Eye Res, 1999 February, 18(2):91-
`103b; “Cyclosporine distribution into the conjunctiva, cor-
`nea, lacrimal gland, and systemic blood following topical
`dosing of cyclosporine to rabbit, dog, and human eyes,”
`Acheamponget al, Adv Exp Med Biol, 1998, 438:1001-4;
`“Preclinical safety studies of cyclosporine ophthalmic emul-
`sion,’ Angelov et al, Adv Exp Med Biol, 1998, 438:991-5;
`“Cyclosporin & Emulsion & Eye,” Stevensonet al, Ophthal-
`mology, 2000 May, 107(5):967-74; and “Two multicenter,
`randomizedstudiesof the efficacy and safety of cyclosporine
`ophthalmic emulsion in moderate to severe dry eye disease.
`CsA Phase 3 Study Group,”Sall et al, Ophthalmology, 2000
`April, 107(4):631-9. Each of these publications is incorpo-
`rated in its entirety herein by reference.
`In addition,
`cyclosporin A-containing oil-in-water emulsions have been
`clinically tested, under conditions of confidentiality, since the
`mid 1990’s in order to obtain U.S. Food and Drug Adminis-

`less than 0.2%, the amount of castor oil employed has been
`reduced since one of the functions of the castor oil is to

`
`SUMMARYOF THE INVENTION
`
`New methods of treating a human or animal using
`cyclosporin component-containing emulsions have been dis-
`covered. Such methodsprovide substantialoverall efficacy in
`providing desired therapeutic effects.
`In addition, other
`important benefits are obtained employing the present meth-
`ods. For example, patient safety is enhanced.In particular,the
`present methods provide for reduced risks of side effects
`and/or drug interactions. Prescribing physicians advanta-
`geously have increased flexibility in prescribing such meth-
`ods and the compositions useful
`in such methods,
`for
`example, because of the reducedrisks of harmful side effects
`and/or drug interactions. The present methods can beeasily
`practiced. In short, the present methods provide substantial
`and acceptable overall efficacy, together with other advan-
`tages, such as increased safety and/orflexibility.
`In one aspect of the present invention, the present methods
`comprise administering to an eye of a human or animal a
`composition in the form of an emulsion comprising water, a
`hydrophobic component and a cyclosporin component in a
`therapeutically effective amountof less than 0.1% by weight
`of the composition. The weightratio of the cyclosporin com-
`ponent to the hydrophobic componentis less than 0.08.
`It has been foundthat the relatively increased amounts of
`hydrophobic componenttogether with relatively reduced, yet
`therapeutically effective, amounts of cyclosporin component
`provide substantial and advantageousbenefits. For example,
`the overall efficacy of the present compositions, for example
`in treating dry eye disease, is substantially equal to an iden-
`tical composition in which the cyclosporin componentis
`present in an amount of 0.1% by weight.Further, a relatively
`high concentration of hydrophobic componentis believed to
`provide for a more quick or rapid breaking downorresolving
`of the emulsion in the eye, which reduces vision distortion
`which may be caused bythe presence of the emulsion in the
`eye and/orfacilitates the therapeutic effectiveness ofthe com-
`position. Additionally, and importantly, using reduced
`amounts of the active cyclosporin component mitigates
`against undesirable side effects and/or potential drug interac-
`tions.
`In short, the present invention provides at least one advan-
`tageous benefit, and preferably a plurality of advantageous
`benefits.
`
`The present methods are useful in treating any suitable
`condition which is therapeutically sensitive to or treatable
`with cyclosporin components. Such conditionspreferably are
`ophthalmic or ocular conditions, that is relating to or having
`to do with one or moreparts of an eye of a humanor animal.

`treated with cyclosporin components include an absolute or
`partial deficiency in aqueoustear production (keratoconjunc-
`tivitis sicca, or KCS). Topical administration to a patient’s
`tear deficient eye can increase tear production in the eye. The
`treatment can further serve to correct corneal and conjuncti-
`val disorders exacerbated by tear deficiency and KCS, such as
`corneal scarring, cornealulceration,inflammationofthe cor-
`nea or conjunctiva, filamentary?keratisis, mucopurulent dis-

`Employing reduced concentrations of cyclosporin compo-
`nent, as in the present invention, is advantageously effective
`to provide the blood of the humanor animal undertreatment
`with reduced concentrations of cyclosporin component, pref-
`erably with substantially no detectable concentration of the
`cyclosporin component. The cyclosporin componentconcen-
`tration of blood can be advantageously measured using a
`validated liquid chromatography/mass spectrometry-mass
`spectrometry (VLC/MS-MS) analytical method, such as
`described elsewhere herein.

`Any suitable cyclosporin component effective in the
`present methods maybe used.
`Cyclosporins are a group of nonpolar cyclic oligopeptides
`with known immunosuppressant activity. Cyclosporin A,
`along with several other minor metabolites, cyclosporin B
`through I, have been identified. In addition, a number of
`synthetic analogs have been prepared.
`In general, commercially available cyclosporins may con-
`tain a mixture of several individual cyclosporins which all
`share a cyclic peptide structure consisting of eleven amino
`acid residues with a total molecular weight ofabout 1,200, but
`with different substituents or configurations of some of the
`amino acids.
`The term “cyclosporin component” as used herein is
`intendedto include any individual memberofthe cyclosporin
`group andderivatives thereof, as well as mixtures of two or
`more individual cyclosporins and derivatives thereof.
`Particularly preferred cyclosporin components include,
`without limitation, cyclosporin A, derivatives of cyclosporin
`A and the like and mixtures thereof. Cyclosporin A is an
`especially useful cyclosporin component.
`Anysuitable hydrophobic component may be employed in
`the present invention. Advantageously, the cyclosporin com-
`ponent is solubilized in the hydrophobic component. The
`hydrophobic component may be considered as comprising a
`discontinuous phase in the presently useful cyclosporin com-
`ponent-containing emulsions.
`The hydrophobic componentpreferably is present in the
`emulsion compositions in an amount greater than about
`0.625% by weight. For example, the hydrophobic component
`may be present in an amountofup to about 1.0% by weight or
`about 1.5% by weight or more of the composition.
`Preferably, the hydrophobic component comprises one or
`moreoily materials. Examples ofuseful oil materials include,
`without limitation, vegetable oils, animal oils, mineraloils,
`synthetic oils and the like and mixtures thereof. In a very
`useful embodiment, the hydrophobic component comprises
`one or more higherfatty acid glycerides. Excellent results are
`obtained when the hydrophobic component comprises castor
`oil.
`
`The presently useful compositions may include one or
`more other components in amounts effective to facilitate the
`usefulness and effectiveness of the compositions. Examples

`of such other components include, without limitation, emul-
`sifier components,
`tonicity components, polyelectrolyte
`components, surfactant components, viscosity inducing com-
`ponents, acids and/or bases to adjust the pH of the composi-
`tion, buffer components, preservative components and the
`like. Components may be employed which are effective to
`perform two or more functionsin the presently useful com-
`positions. For example, components which are effective as
`both emulsifiers and surfactants may be employed, and/or
`components whichare effective as both polyelectrolyte com-
`ponents
`and viscosity inducing components may be
`employed. The specific composition chosen for use in the
`present
`invention advantageously is selected taking into
`account various factors present in the specific application at
`hand,
`for example,
`the desired therapeutic effect
`to be
`achieved, the desired properties of the compositions to be
`employed, the sensitivities of the human or animal to whom
`the composition is to be administered, and the like factors.
`The presently useful compositions advantageously are
`ophthalmically acceptable. A composition, component or
`material is ophthalmically acceptable whenit is compatible
`with ocular tissue, that is, it does not cause significant or
`undue detrimental effects when brought into contact with
`oculartissues.
`
`Such compositions have pH’s within the physiological
`range ofabout6 to about 10, preferably in a range ofabout 7.0
`to about 8.0 and more preferably in a range of about 7.2 to
`about 7.6.
`
`The present methodspreferably provide for an administer-
`ing step comprising topically administering the presently use-
`ful compositions to the eye or eyes of a humanor animal.
`Each and every feature described herein, and each and

`
`DETAILED DESCRIPTION
`
`The present methodsare effective for treating an eye of a
`humanor animal. Such methods, in general, comprise admin-
`istering, preferably topically administering, to an eye of a
`humanor animal a cyclosporin component-containing emul-
`sion. The emulsion contains water, for example U.S. pure
`water, a hydrophobic component and a cyclosporin compo-
`nent ina therapeutically effective amountofless than 0.1% by
`weight of the emulsion. In addition, beneficial results have
`been found whenthe weightratio of the cyclosporin compo-
`nent to the hydrophobic componentis less than 0.08.
`As noted above, the present administering step preferably
`includes topically administering the emulsion to the eye of a
`patient of a human or animal. Such administering may
`involve a single use of the presently useful compositions, or
`repeated or periodic use of such compositions, for example,
`as required or desired to achieve the therapeutic effect to be
`obtained. The topical administration of the presently useful
`composition may involve providing the composition in the
`form of eye drops or similar form or other form so as to
`facilitate such topical administration.
`The present methods have been foundto be very effective
`in providing the desired therapeutic effect or effects while, at
`the same time, substantially reducing, or even substantially
`eliminating, side effects which mayresult from the presence
`of the cyclosporin componentin the blood of the human or

`animalbeing treated, and eye irritation which,in the past, has
`been caused by the presence ofcertain componentsin priorart
`cyclosporin-containing emulsions. Also,
`the use of the
`present compositions which include reduced amounts of the
`cyclosporin components allow for more frequent administra-
`tion of the present compositions to achieve the desired thera-
`peutic effect or effects without substantially increasing the
`risk of side effects and/or eye irritation.
`The present methods are useful in treating any condition
