(15) Crystalline L-Arginine Salt of Compound 1
(16) The crystalline free-plate habit or morphology and processes useful in the preparation of a crystalline free-plate habit of L-arginine salt of (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)-benzyloxy)-1,2,3,4-tetrahydrocyclopenta[b]indol-3-yl)acetic acid are described in WO2016/209809. The plates were discovered from the novel synthetic methods and were shown to be thin hexagonal-like plates with two opposite sides of the plate being longer that the other sides (i.e., elongated hexagonal plate). However, due to the thin characteristic of the plates, a complete unbroken plate is rarely seen. Instead, what is generally observed are large to small broken pieces of the thin hexagonal-like plates. It is understood by those skilled in the art that microscopy is one of the more useful techniques to distinguish two crystalline habits or morphologies. This is particularly useful when 2 or more morphologies are associated with the same or substantially the same crystal phase as is the case with the L-arginine salt of Compound 1. Comparing the PXRD patterns of the habit prepared previously (i.e., WO2011/094008 and Example 2 infra) and the plate habit prepared as described in WO2016/209809 (i.e., see
(17) Although the two habits revealed the same or substantially the same PXRD pattern, a higher degree of crystallinity was observed for the plate habit as indicated by substantially higher peak intensities and yet lower sample-related background scatter (i.e., a lower amorphous halo contribution). Since sample size and sample preparation can affect peak intensities and sample-related background scatter, and since the two habits share the same crystal phase, PXRD may not be considered the most appropriate test method to distinguish between two habits. However, PXRD does allow for determining whether two habits have the same crystal phase or different crystal phases. For determining different habits, microscopy is one of the more useful methods. Accordingly, the skilled person would be capable of reviewing a micrograph for a crystal habit and readily determine the crystal habit.
(18) In addition to the techniques recognized in the art, specific surface can also be used to characterize a habit, such as the free-plates. Accordingly, the specific surface area values disclosed in the present invention have been obtained by means of a specific surface area analysis technique based on the BET (Brunauer, Emmett and Teller) theory, which is a well-accepted theory known in the art for the calculation of surface areas of solids by means of measuring their physical adsorption of gas molecules (see: Brunauer, S.; Emmett, P. H.; and Teller, E.; J. Am. Chem. Soc., 1938, 60, 309). In particular, the specific surface area values measured in the present invention have been calculated from the BET surface area plot obtained by measuring the quantity of nitrogen gas molecules adsorbed by a weighted amount of solid at different relative pressures (P/P.sub.0) within the range 0.05-0.3 (P/P.sub.0), at 77.3 K. The measurement of the adsorption of gas molecules was carried out by means of a Micromeritics™ TriStar II BET surface analyzer having the characteristics as set out below in Example 4. Namely, nitrogen gas was used for the adsorption measurement. The sample for each analysis was degassed at 25° C. for 960 minutes under vacuum (i.e., 100 mm/Hg). The determination of the adsorption of nitrogen was measured at 77.3 K at eleven relative pressures (P/P.sub.0) sufficiently dispersed within the range of about 0.05 to about 0.30 (i.e. eleven absolute pressures in the range of about 36 mm Hg to about 223 mm Hg relative to the saturated pressure at the time of measurement that ranged from about 738 mmHg to about 743 mmHg).
(19) One aspect of the present invention relates to a novel crystalline plate morphology of L-arginine salt of (R)-2-(7-(4-cyclopentyl-3-(trifluoromethyl)benzyloxy)-1,2,3,4-tetrahydrocyclo-penta[b]indol-3-yl)acetic acid as described herein.

(186) Pharmaceutical Compositions
(187) A further aspect of the present invention pertains to pharmaceutical compositions comprising one or more compounds as described herein and one or more pharmaceutically acceptable carriers. Some embodiments pertain to pharmaceutical compositions comprising a compound of the present invention and a pharmaceutically acceptable carrier.
(188) Some embodiments of the present invention include a method of producing a pharmaceutical composition comprising admixing at least one compound according to any of the compound embodiments disclosed herein and a pharmaceutically acceptable carrier.
(189) Formulations may be prepared by any suitable method, typically by uniformly mixing the active compound(s) with liquids or finely divided solid carriers, or both, in the required proportions and then, if necessary, forming the resulting mixture into a desired shape.
(190) Conventional excipients, such as binding agents, fillers, acceptable wetting agents, tabletting lubricants and disintegrants may be used in tablets and capsules for oral administration. Liquid preparations for oral administration may be in the form of solutions, emulsions, aqueous or oily suspensions and syrups. Alternatively, the oral preparations may be in the form of dry powder that can be reconstituted with water or another suitable liquid vehicle before use. Additional additives such as suspending or emulsifying agents, non-aqueous vehicles (including edible oils), preservatives and flavorings and colorants may be added to the liquid preparations. Parenteral dosage forms may be prepared by dissolving the compound of the invention in a suitable liquid vehicle and filter sterilizing the solution before filling and sealing an appropriate vial or ampule. These are just a few examples of the many appropriate methods well known in the art for preparing dosage forms.
(191) A compound of the present invention can be formulated into pharmaceutical compositions using techniques well known to those in the art. Suitable pharmaceutically acceptable carriers, outside those mentioned herein, are known in the art; for example, see Remington, The Science and Practice of Pharmacy, 20.sup.th Edition, 2000, Lippincott Williams & Wilkins, (Editors: Gennaro et al.)
(192) While it is possible that, for use in the prophylaxis or treatment, a compound of the invention may, in an alternative use, be administered as a raw or pure chemical, it is preferable however to present the compound or active ingredient as a pharmaceutical formulation or composition further comprising a pharmaceutically acceptable carrier.
(193) The invention thus further provides pharmaceutical formulations comprising a compound of the invention or a pharmaceutically acceptable salt, solvate, hydrate or derivative thereof together with one or more pharmaceutically acceptable carriers thereof and/or prophylactic ingredients. The carrier(s) must be “acceptable” in the sense of being compatible with the other ingredients of the formulation and not overly deleterious to the recipient thereof.
(194) Pharmaceutical formulations include those suitable for oral, rectal, nasal, topical (including buccal and sub-lingual), vaginal or parenteral (including intramuscular, sub-cutaneous and intravenous) administration or in a form suitable for administration by inhalation, insufflation or by a transdermal patch. Transdermal patches dispense a drug at a controlled rate by presenting the drug for absorption in an efficient manner with a minimum of degradation of the drug. Typically, transdermal patches comprise an impermeable backing layer, a single pressure sensitive adhesive and a removable protective layer with a release liner. One of ordinary skill in the art will understand and appreciate the techniques appropriate for manufacturing a desired efficacious transdermal patch based upon the needs of the artisan.
(195) The compounds of the invention, together with a conventional adjuvant, carrier, or diluent, may thus be placed into the form of pharmaceutical formulations and unit dosages thereof and in such form may be employed as solids, such as tablets or filled capsules, or liquids such as solutions, suspensions, emulsions, elixirs, gels or capsules filled with the same, all for oral use; in the form of suppositories for rectal administration; or in the form of sterile injectable solutions for parenteral (including subcutaneous) use. Such pharmaceutical compositions and unit dosage forms thereof may comprise conventional ingredients in conventional proportions, with or without additional active compounds or principles and such unit dosage forms may contain any suitable effective amount of the active ingredient commensurate with the intended daily dosage range to be employed.
(196) For oral administration, the pharmaceutical composition may be in the form of, for example, a tablet, capsule, suspension or liquid. The pharmaceutical composition is preferably made in the form of a dosage unit containing a particular amount of the active ingredient. Examples of such dosage units are capsules, tablets, powders, granules or suspensions, with conventional additives such as lactose, mannitol, corn starch or potato starch; with binders such as crystalline cellulose, cellulose derivatives, acacia, corn starch or gelatins; with disintegrators such as corn starch, potato starch or sodium carboxymethyl-cellulose; and with lubricants such as talc or magnesium stearate. The active ingredient may also be administered by injection as a composition wherein, for example, saline, dextrose or water may be used as a suitable pharmaceutically acceptable carrier.
(197) Compounds of the present invention or a salt, solvate, hydrate or physiologically functional derivative thereof can be used as active ingredients in pharmaceutical compositions, specifically as S1P1 receptor modulators. The term “active ingredient” is defined in the context of a “pharmaceutical composition” and is intended to mean a component of a pharmaceutical composition that provides the primary pharmacological effect, as opposed to an “inactive ingredient” which would generally be recognized as providing no pharmaceutical benefit.
(198) The dose when using the compounds of the present invention can vary and as is customary and known to the physician, it is to be tailored to the individual conditions in each individual case. It depends, for example, on the nature and severity of the illness to be treated, on the condition of the individual, on the compound employed or on whether an acute or chronic disease state is treated or prophylaxis is conducted or on whether further active compounds are administered in addition to the compounds of the present invention. Representative doses of the present invention include, but are not limited to, about 1 mg to about 5 mg, about 1 mg, about 1.25 mg, about 1.5 mg, about 1.75 mg, about 2 mg, about 2.25 mg, about 2.5 mg, about 2.75 mg, about 3 mg, about 3.25 mg, about 3.5 mg, about 3.75 mg, about 4 mg, about 4.25 mg, about 4.5 mg, about 4.75 mg, and about 5 mg. Multiple doses may be administered during the day, especially when relatively large amounts are deemed to be needed, for example 2, 3 or 4 doses. Depending on the individual and as deemed appropriate by the individual's physician or caregiver it may be necessary to deviate upward or downward from the doses described herein.
(199) The amount of active ingredient or an active salt, solvate or hydrate derivative thereof, required for use in treatment will vary not only with the particular salt selected but also with the route of administration, the nature of the condition being treated and the age and condition of the individual and will ultimately be at the discretion of the attendant physician or clinician. Representative factors include the type, age, weight, sex, diet and medical condition of the individual, the severity of the disease, the route of administration, pharmacological considerations such as the activity, efficacy, pharmacokinetic and toxicology profiles of the particular compound employed, whether a drug delivery system is utilized, whether an acute or chronic disease state is being treated or prophylaxis is conducted or whether further active compounds are administered in addition to the compounds of the present invention and as part of a drug combination. The dosage regimen for treating a disease condition with the compounds and/or compositions of this invention is selected in accordance with a variety factors including those cited above. Thus, the actual dosage regimen employed may vary widely and therefore may deviate from a preferred dosage regimen and one skilled in the art will recognize that dosage and dosage regimens outside these typical ranges can be tested and, where appropriate, may be used in the methods of this invention.
(200) The desired dose may conveniently be presented in a single dose or as divided doses administered at appropriate intervals, for example, as 2, 3, 4 or more sub-doses per day. The sub-dose itself may be further divided, e.g., into a number of discrete loosely spaced administrations. The daily dose can be divided, especially when relatively large amounts are administered as deemed appropriate, into several, for example 2, 3 or 4 part administrations. If appropriate, depending on individual behavior, it may be necessary to deviate upward or downward from the daily dose indicated.
(201) For preparing pharmaceutical compositions from the compounds of the present invention, the suitable pharmaceutically acceptable carrier can be either solid, liquid or a mixture of both. Solid form preparations include powders, tablets, pills, capsules, cachets, suppositories and dispersible granules. A solid carrier can be one or more substances which may also act as diluents, flavoring agents, solubilizers, lubricants, suspending agents, binders, preservatives, tablet disintegrating agents, or encapsulating materials.
(202) In powders, the carrier is a finely divided solid which is in a mixture with the finely divided active component.
(203) In tablets, the active component is mixed with the carrier having the necessary binding capacity in suitable proportions and compacted to the desired shape and size.
(204) The powders and tablets may contain varying percentage amounts of the active compound. A representative amount in a powder or tablet may be from 0.5 to about 90 percent of the active compound. However, an artisan would know when amounts outside of this range are necessary. Suitable carriers for powders and tablets include magnesium carbonate, magnesium stearate, talc, sugar, lactose, pectin, dextrin, starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose, a low melting wax, cocoa butter and the like. The term “preparation” is intended to include the formulation of the active compound with encapsulating material as carrier providing a capsule in which the active component, with or without carriers, is surrounded by a carrier, which is thus in association with it. Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets and lozenges can be used as solid forms suitable for oral administration.
(205) For preparing suppositories, a low melting wax, such as an admixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein (e.g., by stirring). The molten homogenous mixture is then poured into convenient sized molds, allowed to cool and thereby to solidify.
(206) Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate.
(207) Liquid form preparations include solutions, suspensions and emulsions, for example, water or water-propylene glycol solutions. For example, parenteral injection liquid preparations can be formulated as solutions in aqueous polyethylene glycol solution. Injectable preparations, for example, sterile injectable aqueous or oleaginous suspensions may be formulated according to the known art using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a nontoxic parenterally acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Among the acceptable vehicles and solvents that may be employed are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose, any bland fixed oil may be employed including synthetic mono- or diglycerides. In addition, fatty acids such as oleic acid find use in the preparation of injectables.
(208) The compounds according to the present invention may thus be formulated for parenteral administration (e.g. by injection, for example bolus injection or continuous infusion) and may be presented in unit dose form in ampoules, pre-filled syringes, small volume infusion or in multi-dose containers with an added preservative. The pharmaceutical compositions may take such forms as suspensions, solutions, or emulsions in oily or aqueous vehicles and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents. Alternatively, the active ingredient may be in powder form, obtained by aseptic isolation of sterile solid or by lyophilization from solution, for constitution with a suitable vehicle, e.g. sterile, pyrogen-free water, before use.
(209) Aqueous formulations suitable for oral use can be prepared by dissolving or suspending the active component in water and adding suitable colorants, flavors, stabilizing and thickening agents, as desired.
(210) Aqueous suspensions suitable for oral use can be made by dispersing the finely divided active component in water with viscous material, such as natural or synthetic gums, resins, methylcellulose, sodium carboxymethylcellulose, or other well-known suspending agents.
(211) Also included are solid form preparations which are intended to be converted, shortly before use, to liquid form preparations for oral administration. Such liquid forms include solutions, suspensions and emulsions. These preparations may contain, in addition to the active component, colorants, flavors, stabilizers, buffers, artificial and natural sweeteners, dispersants, thickeners, solubilizing agents and the like.
(212) For topical administration to the epidermis the compounds according to the invention may be formulated as ointments, creams or lotions, or as a transdermal patch.
(213) Ointments and creams may, for example, be formulated with an aqueous or oily base with the addition of suitable thickening and/or gelling agents. Lotions may be formulated with an aqueous or oily base and will in general also contain one or more emulsifying agents, stabilizing agents, dispersing agents, suspending agents, thickening agents, or coloring agents.
(214) Formulations suitable for topical administration in the mouth include lozenges comprising the active agent in a flavored base, usually sucrose and acacia or tragacanth; pastilles comprising the active ingredient in an inert base such as gelatin and glycerin or sucrose and acacia; and mouthwashes comprising the active ingredient in a suitable liquid carrier.
(215) Solutions or suspensions are applied directly to the nasal cavity by conventional means, for example with a dropper, pipette or spray. The formulations may be provided in single or multi-dose form. In the latter case of a dropper or pipette, this may be achieved by the individual administering an appropriate, predetermined volume of the solution or suspension. In the case of a spray, this may be achieved for example by means of a metering atomizing spray pump.
(216) Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurized pack with a suitable propellant. If the compounds of the present invention or pharmaceutical compositions comprising them are administered as aerosols (e.g., nasal aerosols, by inhalation), this can be carried out, for example, using a spray, a nebulizer, a pump nebulizer, an inhalation apparatus, a metered inhaler or a dry powder inhaler. Pharmaceutical forms for administration of the compounds of the present invention as an aerosol can be prepared by processes well known to the person skilled in the art. Solutions or dispersions of the compounds of the present invention or a pharmaceutically acceptable salt, solvate, hydrate or derivative thereof in water, water/alcohol mixtures or suitable saline solutions, for example, can be employed using customary additives (e.g., benzyl alcohol or other suitable preservatives), absorption enhancers for increasing the bioavailability, solubilizers, dispersants and others and, if appropriate, customary propellants (e.g., carbon dioxide, CFCs, such as, dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane and the like). The aerosol may conveniently also contain a surfactant such as lecithin. The dose of drug may be controlled by provision of a metered valve.
(217) In formulations intended for administration to the respiratory tract, including intranasal formulations, the compound will generally have a small particle size for example of the order of 10 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization. When desired, formulations adapted to give sustained release of the active ingredient may be employed.
(218) Alternatively, the active ingredients may be provided in the form of a dry powder (e.g., a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP)). Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form (e.g., capsules, cartridges) as for gelatin or blister packs from which the powder may be administered by means of an inhaler.
(219) The pharmaceutical preparations are preferably in unit dosage forms. In such form, the preparation is subdivided into unit doses containing appropriate quantities of the active component. The unit dosage form can be a packaged preparation, the package containing discrete quantities of preparation, such as packeted tablets, capsules and powders in vials or ampoules. Also, the unit dosage form can be a capsule, tablet, cachet, or lozenge itself, or it can be the appropriate number of any of these in packaged form.
(220) In some embodiments, the compositions are tablets or capsules for oral administration.
(221) In some embodiments, the compositions are liquids for intravenous administration.
(222) The compounds according to the invention may optionally exist as pharmaceutically acceptable salts including pharmaceutically acceptable acid addition salts prepared from pharmaceutically acceptable non-toxic acids including inorganic and organic acids. Representative acids include, but are not limited to, acetic, benzenesulfonic, benzoic, camphorsulfonic, citric, ethenesulfonic, dichloroacetic, formic, fumaric, gluconic, glutamic, hippuric, hydrobromic, hydrochloric, isethionic, lactic, maleic, malic, mandelic, methanesulfonic, mucic, nitric, oxalic, pamoic, pantothenic, phosphoric, succinic, sulfiric, tartaric, oxalic, p-toluenesulfonic and the like, such as those pharmaceutically acceptable salts listed by Berge et al., Journal of Pharmaceutical Sciences, 66:1-19 (1977), incorporated herein by reference in its entirety.
(223) The acid addition salts may be obtained as the direct products of compound synthesis. In the alternative, the free base may be dissolved in a suitable solvent containing the appropriate acid and the salt isolated by evaporating the solvent or otherwise separating the salt and solvent. The compounds of this invention may form solvates with standard low molecular weight solvents using methods known to the skilled artisan.
(224) Compounds of the present invention can be converted to “pro-drugs.” The term “pro-drugs” refers to compounds that have been modified with specific chemical groups known in the art and that when administered into an individual undergo biotransformation to give the parent compound. Pro-drugs can thus be viewed as compounds of the invention containing one or more specialized non-toxic protective groups used in a transient manner to alter or to eliminate a property of the compound. In one general aspect, the “pro-drug” approach is utilized to facilitate oral absorption. A thorough discussion is provided in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems Vol. 14 of the A.C.S. Symposium Series; and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987, both of which are hereby incorporated by reference in their entirety.
(225) Some embodiments of the present invention include a method of producing a pharmaceutical composition for “combination-therapy” comprising admixing at least one compound according to any of the compound embodiments disclosed herein, together with at least one known pharmaceutical agent as described herein and a pharmaceutically acceptable carrier.
(226) As will be recognized, the steps of the methods of the present invention need not be performed any particular number of times or in any particular sequence. Additional objects, advantages and novel features of this invention will become apparent to those skilled in the art upon examination of the following examples thereof, which are intended to be illustrative and not intended to be limiting.

(270) 5) Inflammatory Bowel Disease Questionnaire (IBDQ)
(271) The IBDQ is used to measure how the individual has felt during the last two weeks. The IBDQ is used during screening and at weeks 2, 4, 8, and 12.
(272) 6) Skin Punch Biopsies
(273) Skin punch biopsies (from healthy skin and from target lesion) are collected before treatment and at week 8 or 12. Immunohistochemistry and other analysis methods (such as RT-PCR) are performed to evaluate immune cell infiltration, cytokine expression in the skin and other inflammatory parameters.
(274) 7) C-reactive Protein (CRP)
(275) Blood samples for analysis of C-reactive protein (CRP) are collected at screening; at weeks 0, 1, 2, 4, 8, and 12; and at the two-week follow-up.
(276) Efficacy Endpoints
(277) UC endpoint: Change from baseline in stool frequency, rectal bleeding, PGA (Physicians Global Assessments) at weeks 1, 2, 4, 8 and 12. CD endpoint: Change from baseline in disease activity score at week 1, 2, 4, 8 and 12. Change from baseline in endoscopic improvement/histologic healing using endoscopy or flexible proctosigmoidoscopy (only if there are signs of inflammation at screening another evaluation is performed at week 12). Change from baseline in level of fecal calprotectin at week 4, 8 and 12. Change from baseline in Physician Global Assessments for active skin extra-intestinal manifestations (PG, EN and psoriasis) at week 1, 2, 4, 8 and 12. Change from baseline in Patients Global Assessments for active skin extra-intestinal manifestations (PG, EN and psoriasis) at week 1, 2, 4, 8 and 12. Change from baseline in the Dermatology Life Quality Index (DLQI) score at week 1, 2, 4, 8 and 12. Psoriasis endpoint only (all other endpoints are for all skin manifestations): Change from baseline in Psoriasis Area and Severity Index (PASO score at week 1, 2, 4, 8 and 12. Change from baseline in Inflammatory Bowel Disease Questionnaire (IBDQ) score at week 2, 4, 8 and 12. Skin punch biopsies (from healthy skin and from target lesion) are collected before treatment and at week 8 or 12. Immunohistochemistry and other analyzing methods such as RT-PCR are performed to evaluate immune cell infiltration, cytokine expression in the skin and other inflammatory parameters. Change from baseline in C-reactive protein (CRP) at weeks 1, 2, 4, 8 and 12. Change from baseline in leucocyte characterization. Change from baseline in lymphocyte counts at weeks 1, 2, 4, 8 and 12.

Clinical Trial for Pyoderma Gangrenosum with Compound 1
(278) A clinical trial is conducted in individuals aged 18 to 80 years old (inclusive) who have active pyoderma gangrenosum (PG) ulcers. All visits in the study are ambulatory visits. The screening period lasts up to four weeks and is followed by a 12-week treatment period. During the treatment period, individuals take one 2 mg tablet of Compound 1 once per day. The last dose is taken one day before the end of the treatment period (week 12). A follow-up visit takes place two weeks after the end of treatment.
(279) Screening Visit
(280) Each individual visits the study site for screening assessment within 4 weeks of the planned start of the treatment (Day 1). Individuals then undergo screening procedures to determine eligibility.
(281) Individuals return to the study site at Day-1 for confirmation of eligibility, and start the 24-hour ambulatory pre-dose Holter (ECG) monitoring procedure.
(282) Treatment Visits
(283) Baseline Visit (Day 1): Individuals return to the study site to receive the first dose of Compound 1. Individuals are instructed to take the tablet first thing in the morning on an empty stomach. Individuals are advised not to crush, break, chew, or dissolve the tablet and to take study medication with an adequate amount of water. The individuals remain at the study site for at least six hours for safety evaluation. Holter monitoring continues to allow for an overall continuous 24-hour pre- and a 24-hour post-dose monitoring.
(284) Visits at week 2, week 4, week 8, and week 12: Individuals return to the study site and tests are conducted. The last dose of Compound 1 is planned 1 day before the end of the treatment visit at week 12.
(285) Follow Up Visit/End of Study Visit
(286) Visit at week 14 (two weeks after end of treatment): Individuals return to the study site for the final visit.
(287) Permitted Medications
(288) Oral corticosteroids TNF-alpha inhibitor (etanercept, infliximab, adalimumab or other) Oral 5-ASA medication Antidiarrheal treatment OTC analgesics (paracetamol/acetaminophen, NSAIDs)
Efficacy Endpoints Change from baseline (Day 1 pre-dose) to week 12 in Physician Global Assessments for active skin manifestations. Assessment of target lesion/ulceration: 0: Total resolution of target ulcer with no signs of active PG 1: Almost completely healed target ulcer with only minimal signs of active PG 2: Evidence of target ulcer healing which involves at least 50% of ulcer/ulcer margin 3: Evidence of target ulcer healing which involves less than 50% of ulcer/ulcer margin 4: No evidence of target ulcer healing Change from baseline (Day 1 pre-dose) to week 12 in Patient Global Assessments for active skin manifestations: visual analog scale (VAS) for assessment of severity of the disease and severity of pain by patient. Change from baseline (Day 1 pre-dose) to week 12 in Dermatology Life Quality Index (DLQI). Change from baseline (Day 1 pre-dose) to week 12 in CRP levels.
The Following Measures are also Assessed: Imaging (digital photos) of the target lesion. Evaluation of the changes in surface area of target lesion. Punch biopsy (histology).

BET (Brunauer, Emmett, and Teller) Specific Surface Area Method (Plate Habit)
(289) In general, the specific surface areas for crystalline free-plate habit of the non-solvated L-arginine salt of Compound 1 were determined by physical adsorption of nitrogen gas on the surface of the sample from each lot using the well-established technique based on the Brunauer, Emmett, and Teller theory.
(290) The BET surface areas for the samples were measured by Micromeritics Pharmaceutical Services using a Micromeritics™ TriStar II BET surface area analyzer (MicroActive for TriStar II Plus 2.02 Software™). The samples were degassed at 25° C. for 960 minutes under vacuum (i.e., 100 mm/Hg). The determination of the adsorption of N.sub.2 at 77.3 K was measured using a BET surface area eleven-point method with relative pressures in the range of about 0.05 to about 0.3 (P/P.sub.0) for a weighed amount of each sample, see Table 1 below. The analysis was performed per ISO9277.
