Patents Act 1990 COMPLETE SPECIFICATION STANDARD PATENT Applicant(s): SCHERING CORPORATION Invention Title: THE USE OF SUBSTITUTED AZETIDINONE COMPOUNDS FOR THE TREATMENT OF SITOSTEROLEMIA The following statement is a full description of this invention, including the best method of performing it known to me/us: 0 THE USE OF SUBSTITUTED AZETIDINONE COMPOUNDS FOR THE TREATMENT OF SITOSTEROLEMIA CROSS-REFERENCE TO RELATED APPLICATION This application claims the benefit of U.S. Provisional Application SSerial No. 60/264,645 filed January 26, 2001.

SFIELD OF THE INVENTION The present invention provides methods and pharmaceutical compositions for treating or preventing sitosterolemia by administering to a mammal in need of such treatment an effective amount of at least one treatment composition comprising at least one sterol absorption inhibitor and optionally, an effective amount of at least one bile acid sequestrant or other lipid lowering agent.

BACKGROUND OF THE INVENTION Sitosterolemia is a genetic lipid storage disorder characterized by increased levels of sitosterol and other plant sterols in the plasma and other tissues due to increased non-selective intestinal absorption of sterols and decreased hepatic removal. Individuals having sitosterolemia can exhibit one or more of the following conditions: tendon and tuberous xanthomas, arthritis, hemolytic episodes, accelerated atherosclerosis and myocardial infarctions, and can die at an early age due to extensive coronary atherosclerosis. See Nguyen et al., "Regulation of cholesterol biosynthesis in sitosterolemia: effects of lovastatin, cholestyramine, and dietary sterol restriction", Vol 32, Journal of Lipid Research, pp. 1941-1948, (1991), incorporated by reference herein.

Sitosterolemia can be treated with bile acid sequestrants (such as cholestyramine, colesevelam hydrochloride and colestipol), however, these compounds have a tendency to cause constipation in patients and therefore compliance with this treatment is difficult. Bile acid sequestrants (insoluble anion exchange resins) bind bile acids in the intestine, interrupting the enterohepatic circulation of bile acids and causing an increase in the fecal excretion of steroids.

Use of bile acid sequestrants is desirable because of their non-systemic mode of action. Bile acid sequestrants can lower intrahepatic cholesterol and promote the 2 Ssynthesis of apo B/E (LDL) receptors which bind LDL from plasma to further reduce Cholesterol levels in the blood.

Alternative treatments include ileal bypass surgery and selective low density lipoprotein plasmapheresis, which are physically undesirable forthe patient.

An improved treatment for sitosterolemia is needed which can reduce the Sconcentration of sterols in plasma and tissues and inhibit associated debilitating Cphysical effects. Also, treatments which reduce the plasma or tissue concentration N.of non-cholesterol sterols such as phytosterols and 5c-stanols are needed.

In SUMMARY OF THE INVENTION The present invention provides a method of treating or preventing sitosterolemia, comprising administering to a mammal in need of such treatment an effective amount of at least one sterol absorption inhibitor, or pharmaceutically acceptable salt or solvate of the least one sterol absorption inhibitor, or prodrug of the at least one sterol absorption inhibitor or pharmaceutically acceptable salt or solvate of the least one sterol absorption inhibitor, or mixture thereof.

c 10 Generally, compounds of Formulae I-XI can be prepared by known methods, for example WO 93/02048 describes the preparation of compounds wherein -R 1

-Q-

is alkylene, alkenylene or alkylene interrupted by a hetero atom, phenylene or cycloalkylene; WO 94/17038 describes the preparation of compounds wherein Q is a spirocyclic group; WO 95/08532 describes the preparation of compounds wherein -R 1 is a hydroxy-substituted alkylene group; PCT/US95/03196 describes compounds wherein -Rl-Q- is a hydroxy-substituted alkylene attached to the Ar 1 moiety through an or S(0)0-2- group; and U.S. Serial No. 08/463,619, filed June 5, 1995, describes the preparation of compounds wherein -R 1 is a hydroxy-substituted alkylene group attached the azetidinone ring by a -S(0)0-2group, each of which is incorporated herein by reference.

As used herein, the term "alkyl" or "lower alkyl" means straight or branched alkyl chains of 1 to 6 carbon atoms and "alkoxy" similarly refers to alkoxy groups having 1 to 6 carbon atoms. Non-limiting examples of suitable lower alkyl groups include methyl, ethyl, propyl and butyl groups.

"Alkenyl" means straight or branched carbon chains having one or more double bonds in the chain, conjugated or unconjugated. Similarly, "alkynyl" means straight or branched carbon chains having one or more triple bonds in the chain.

Where an alkyl, alkenyl or alkynyl chain joins two other variables and is therefore bivalent, the terms alkylene, alkenylene and alkynylene are used.

"Cycloalkyl" means a saturated carbon ring of 3 to 6 carbon atoms, while "cycloalkylene" refers to a corresponding bivalent ring, wherein the points of attachment to other groups include all positional isomers.

"Halogeno" refers to fluorine, chlorine, bromine or iodine radicals.

S"Aryl" means phenyl, naphthyl, indenyl, tetrahydronaphthyl or indanyl.

IN 5 The statements wherein, for example, R 1 9

R

2 0 and R 2 5 are said to be independently selected from a group of substituents, means that R 19

R

2 0 and R 2 are independently selected, but also that where an R 1 9, R 2 0 or R 2 5 variable tVt occurs more than once in a molecule, those occurrences are independently 0selected if R 10 is -OR 1 9 wherein R 1 9 is hydrogen, R 1 1 can be -OR 1 9 0o wherein R 1 9 is lower alkyl). Those skilled in the art will recognize that the size and nature of the substituent(s) will affect the number of substituents which can be present.

Compounds of the invention have at least one asymmetrical carbon atom and therefore all isomers, including enantiomers, stereoisomers, rotamers, tautomers, racemates of the compounds of Formula (I-XI) (where they exist) are contemplated as being part of this invention. The invention includes d and I isomers in both pure form and in admixture, including racemic mixtures. Isomers can be prepared using conventional techniques, either by reacting optically pure or optically enriched starting materials or by separating isomers of a compound of the Formulae I-XI. Isomers may also include geometric isomers, when a double bond is present.

Those skilled in the art will appreciate that for some of the compounds of the Formulas I-XI, one isomer will show greater pharmacological activity than other isomers.

Compounds of the invention with an amino group can form pharmaceutically acceptable salts with organic and inorganic acids. Examples of suitable acids for salt formation are hydrochloric, sulfuric, phosphoric, acetic, citric, oxalic, malonic, salicylic, malic, fumaric, succinic, ascorbic, maleic, methanesulfonic and other mineral and carboxylic acids well known to those in the art. The salt is prepared by contacting the free base form with a sufficient amount of the desired acid to produce a salt. The free base form may be regenerated by treating the salt with a suitable dilute aqueous base solution such as dilute aqueous sodium bicarbonate.

The free base form differs from its respective salt form somewhat in certain O 41 Sphysical properties, such as solubility in polar solvents, but the salt is otherwise Sequivalent to its respective free base forms for purposes of the invention.

Certain compounds of the invention are acidic those compounds which possess a carboxyl group). These compounds form pharmaceutically acceptable salts with inorganic and organic bases.

r V .59 SThe pharmaceutical treatment compositions of the present invention can be U administered to a mammal in need of such treatment in a pharmaceutically or therapeutically effective amount to treat sitosterolemia and/or reduce the level of sterol(s) in the plasma and tissues.

The term "therapeutically effective amount" means that amount of a D therapeutic agent of the composition, such as the bile acid sequestrant(s), sterol absorption inrihibitor(s) and other pharmacological or therapeutic agents described below, that will elicit a biological or medical response of a tissue, system, animal or In mammal that is being sought by the administrator (such as a researcher, doctor or veterinarian) which includes alleviation of the symptoms of the sitosterolemic condition or disease being treated and the prevention, slowing or halting of progression of the sitosterolemic condition, reduction of the concentration of sterol(s) and/or 5a-stanol(s) in the plasma and/or tissues, and/or preventing or reducing the risk of the occurrence of a biological or medical event (such as a coronary event).

As used herein, "combination therapy" or "therapeutic combination" means the administration of two or more therapeutic agents, such as sterol absorption inhibitor(s) and bile acid sequestrant(s) or other therapeutic vascular agents, to prevent or treat sitosterolemia and/or reduce the level of sterol(s) in the plasma and tissues. As used herein, "vascular" comprises cardiovascular, cerebrovascular and combinations thereof. Such administration includes coadministration of these therapeutic agents in a substantially simultaneous manner, such as in a single tablet or capsule having a fixed ratio of active ingredients or in multiple, separate capsules for each therapeutic agent. Also, such administration includes use of each .type of therapeutic agent in a sequential manner. In either case, the treatment using the combination therapy will provide beneficial effects in treating the sitosterolemic condition and/or reduce the level of sterol(s) in the plasma and tissues. A potential advantage of the combination therapy disclosed herein may be a reduction in the required amount of an individual therapeutic compound or the overall total amount of therapeutic compounds that are effective in treating the sitosterolemic condition and/or reducing the level of sterol(s) in the plasma and tissues. Therapeutic agents can be selected to provide a broader range of complementary effects or complimentary modes of action.

ti. c The daily dose of the sterol absorption inhibitor(s) preferably ranges from o uabout 0.1 to about 30 mg/kg of body weight per day, and more preferably about 0.1 Sto about i5 mg/kg. For an average body weight of 70 kg, the dosage level therefore ranges from about 1 mg to about 1000 mg of sterol absorption inhibitor(s) per day, given in a single dose or 2-4 divided doses. The exact dose, however, is IDdetermined by the attending clinician and is dependent on the potency of the \compound administered, the age, weight, condition and response of the patient.

c- For the pharmaceutical treatment compositions of the present invention in I which the sterol absorption inhibitor(s) is administered concomitantly or in combination with a bile acid sequestrant, the typical daily dose of the sequestrant preferably ranges from about 0.1 to about 80 mg/kg of body weight per day administered in single or divided dosages, usually once or twice a day. For example, preferably about 10 to about 40 mg per dose is given 1 to 2 times a day, giving a total daily dose of about 10 to about 80 mg per day. The exact dose of Is sterol absorption inhibitor(s) and bile acid sequestrant(s) to be administered is determined by the attending clinician and is dependent on the potency of the compound administered, the age, weight, condition and response of the patient.

Where the sterol absorption inhibitor(s) and bile acid sequestrant(s) are administered in separate dosages, the number of doses of each component given per day may not necessarily be the same, one component may have a greater duration of activity and will therefore need to be administered less frequently.

For the pharmaceutical treatment compositions of the present invention in which the sterol absorption inhibitor(s) is administered concomitantly or in combination with a lipid lowering agent, the typical daily dose of the lipid lowering agent preferably ranges from about 0.1 to about 80 mg/kg of body weight per day administered in single or divided dosages, usually once or twice a day. For example, for HMG CoA reductase inhibitors, preferably about 10 to about 40 mg per dose is given 1 to 2 times a day, giving a total daily dose of about 10 to about mg per day. For other lipid lowering agents, preferably about 1 to about 1000 mg per dose is given 1 to 2 times a day, giving a total daily dose ranging from about 1 mg to about 2000 mg per day. The exact dose of sterol absorption inhibitor(s) and lipid lowering agent(s) to be administered is determined by the 61 c attending clinician and is dependent on the potency of the compound administered,

O

Sthe age, weight, condition and response of the patient.

C) Where the sterol absorption inhibitor(s) and lipid lowering agent(s) are administered in separate dosages, the number of doses of each component given per day may not necessarily be the same, one component may have a greater NOduration of activity and will therefore need to be administered less frequently.

EXAMPLE 1 In Vivo Evaluation In Mice In vivo activity of compound VIII in mice was determined by the following procedure: Male ApoE knockout mice, age 6wks, were received from Jackson Laboratory along with age-matched C57BL/J. The mice were housed 5 per cage, normal light cycle, normal diet. Twenty-six mice of each variety were weighed and housed, 1 per cage, in suspended wire cages with normal light cycle, normal diet.

After three days, the mice were reweighed. Based on body weight, the mice were divided into 5 groups for each type of treatment: Control (comrn oil) and Compositions including Compound VIII at 0.3, and mg/kg of body weight per day.

67 c Preparation of Compositions including Compound VIII based on 22g U) average mouse body weight: Dosage of Compound VIII (mg/ml/day) Compound VIII (ml) corn oil (ml) in 0.1 ml corn oil 2.2mg/ml* 10ml=22 mg in 10ml corn oil 3mg/kg 3 ml of 10mg/kg 7 ml corn oil; 1 mg/kg: 3 ml of 3mg/kg 6 ml com oil; o 0.3mg/kg 2ml of 1mg/kg 4.67 ml corn oil.

The mice were gavaged using a feeding needle 30 min before receiving 4

C-

cholesterol (NEN, NEC 018) and 3 H-sitosterol (NEN, CUS 030T). The radioactive dose was prepared from: 114 pL 3 H-sitosterol stock (1 pCi/pL in ethanol); 1.425 mL 14 C-cholesterol stock (40 pCi/mL in ethanol); 5.7 mg cholesterol, Sigma C 8667; 5.7 mg I-sitosterol, Sigma, S 1270; The ethanol was removed under N 2 5.7 ml of corn oil was added, and the mixture was warmed to 60°C; and shaken for 1hr.

Each 0.1ml dose contained 2 pCi 3 H-sitosterol, 0.1 mg cold (non radioactive) sitosterol; 1 pCi 1 4 C-cholesterol, and 0.1 mg cold (non radioactive) cholesterol.

Radioactive content was verified: 5 X 10 pl counted in Beckman LSC (liquid simulation counter). Tritiated sitosterol was used as an "unabsorbable" marker to compare to the absorption of C 4 C]-cholesterol in a mouse fecal isotope ratio cholesterol absorption model.

On the 4 th 5 t h and 6 t days, feces were collected and stored at -20 0 C in vials just before dosing with Control or Compound VIII late in the day. Termination of the experiment on the 7 h day involved sacrifice by exsanguination, removal and weighing of the liver. 3 X -250 mg samples of liver were put in vials. The liver samples were digested with 1ml of 1 N NaOH at 600 overnight, neutralized with 0.1ml 12N HCI and counted for 14 C and 3 H. The blood samples were allowed to clot at room temp for 1 hr, then centrifuged at 1000G for 15 min. The serum was analyzed for total cholesterol (see Wako CII; see Allain CC, Poon LS, Chan CSG, Richmond W, Fu PC.Enzymatic Determination of Total Serum Cholesterol. Clin.

Chem. 1974; 20:470-475, which is incorporated by reference herein) and r S68 N radioactivity (2 X 50pL). Fecal samples were analyzed for radioactivity by combustion in a Packard Oxidizer followed by Beckman LSC.

SIn this experiment, Wild type mice (C57BL/6J) and mice deficient in apoprotein E (Apo E KO) were found to absorb from 0.15-0.38% of the original 3
