Full Text	FORM 2 THE PATENTS ACT, 1970 (39 of 1970) & THE PATENTS RULES, 2003 COMPLETE SPECIFICATION [See section 10, Rule 13] COMBINATION OF HMG-COA REDUCTASE INHIBITOR WITH PHOSPHODIESTERASE 4 INHIBITORS FOR THE TREATMENT OF INFLAMMATORY PULMONARY DISEASES; NYCOMED GMBH, A CORPORATION ORGANIZED AND EXISTING UNDER THE LAWS OF GERMANY, WHOSE ADDRESS IS BYK-GULDEN-STR. 2, 78467 KONSTANZ, GERMANY. THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED. Technical Field The present invention relates to the combination of certain known therapeutic compounds for thera¬peutic purposes. The substances used in the combinations according to the invention are known ac¬tive agents from the phosphodiesterase 4 (PDE4) inhibitor class and active agents from the HMG-CoA-reductase inhibitor class. Background Art Statins are widely used as cholesterol lowering therapeutic agents. They reduce cholesterol levels through competitive inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the key enzyme that regulates cholesterol synthesis. The cholesterol-lowering effect of statins is also due to an increase in the uptake of cholesterol by cells as a result of intracellular cholesterol depletion and enhanced expression of low-density lipoprotein (LDL) receptors. However, statins exhibit properties that are beyond their lipid-lowering effects. These non-lipid-lowe-ring properties involve the inhibition of the isoprenoid pathway including the cholesterol precursor me-valonate which is required as a precursor for the prenylation of a number of proteins leading to a change in function [Drugs of Today; 2004;40: 975-990]. For example simvastatin modulates chemo-kine and chemokine receptor expression by geranylgeranyl isoprenoid pathway in human endothelial cells and macrophages [Veillard NR et al; Simvastatin modulates chemokine and chemokine receptor expression by geranylgeranyl isoprenoid pathway in human endothelial cells and macrophages; Atherosclerosis; 2005 Nov 28; Epub ahead of print]. Statins also have a potential role as antioxidants leading to downregulation of inflammation [Drugs of Today; 2004; 40: 975-990J. Recent research data demonstrated that statins inhibit the induction of the major histocompatibility (MHC) class II expression by interferon-gamma (IFN-gamma), leading to repression of MHC ll-mediated T-cell activation. Fur¬thermore, statins inhibit the expression of specific cell surface receptors on monocytes, adhesion molecules and also integrin-dependent leucocyte adhesion [Timely Top Med Cardiovasc Dis; 2005; 9: E3]. Statins exhibit additional effects on inflammation by decreasing IL-6, IL-8, and MCP-1 synthesis in human vascular smooth muscle cells (VSMC) in vitro [Cardiovas Res; 2003; 59: 755-66]. Simvastatin inhibits growth factor expression and modulates profibrogenic markers in lung fibroblasts [Am J Respir Cell Mol Biol. 2005; 32: 290-300]. Furthermore, statins increase bioavailability of nitric oxide. Cerivas-tatin increased eNOS expression a NO release in human endothelial cells [J Physiol Pharmacol. 2002; 53:585-95], In vivo statins exert anti-inflammatory effects in many models of inflammatory airway dis- eases like asthma and COPD. Simvastatin was shown to inhibit pulmonary inflammatory cell accumu¬lation and il_-4 and IL-5 release into the alveolar lumen after allergeH challenge in mice [J Immunol. 2004; 172: 2903-8]. Simvastatin inhibits cigarette smoking-induced emphysema and pulmonary hyper¬tension in rat lungs [Am J Respir Crit Care Med. 2005; 172: 987-93]. Overall statins exhibit inhibitory properties on inflammation and modulation on the immune system. In the international patent application WOOO/48626 (University of Washington) aerosol compositions of HMG-CoA reductase inhibitors for inhibiting inflammation associated witn a pulmonary disease, such as asthma, interstitial pneumonitis, emphysema, chronic bronchitis, £dult respiratory distress syndro¬me (ARDS) and cystic fibrosis, are described. In EP1275388 (Takeda) several statins are described as useful for the treatment of TNFa associated diseases such as inflammatory diseases including asthma and COPD. In US20050119330 the use of HMG-CoA reductase inhibitors is descibed for the treatment of lung proliferative vascular disorders, such as for example pulmonary hypertension and pulmonary fibrosis. There is pressing, need to improve the treatment of inflammatory puli710nary diseases like asthma and COPD. These inflammatory diseases are characterized by multifact Cyclic nucleotide phosphodiesterase (PDE) inhibitors, particularly innibitors of type 4 (PDE4), are use¬ful in the treatment of a variety of allergic and inflammatory diseases-for example in respiratory dis¬eases, such as asthma and chronic obstructive pulmonary disease. HMG-CoA reductase inhibitors, by a route different from PDE4 inhibitors. are also useful in the treat¬ment of inflammatory diseases. It would be desirable to provide combinations and methods of treatment that can take advantage of the different therapeutic pathways of a PDE4 inhibitor and a HMG-0>A reductase inhibitor to more effectively treat inflammatory disorders, in particular asthma and CO^D- Description of the invention It has now been found that the combined use of a PDE4 inhibitor an^ a HMG-CoA reductase inhibitor potentiates the anti-inflammatory effect of either component alone. Therefore, according to a first aspect of the present invention there \0 provided a pharmaceutical com- position comprising a pharmaceutical formulation including an amount of a PDE4 inhibitor or a phar¬maceutically acceptable salt thereof, an amount of a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof, wherein the first amount and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease, and at least one pharmaceutically acceptable auxiliary. The above-mentioned pharmaceutical composition provides for the administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof with a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof and is thus presented as a single formulation. Alternatively, the PDE4 inhibitor or a pharmaceutically acceptable salt thereof and the HMG-CoA re¬ductase inhibitor or a pharmaceutically acceptable salt thereof may be presented as separate formula¬tions, wherein at least one of those formulations comprises a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and at least one comprises a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof. Thus, there is further provided: A combination product comprising the components: (A) an amount of a PDE4 inhibitor or a pharma¬ceutically acceptable salt thereof; (B) an amount of a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof; wherein the first and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease and wherein each of the components (A) and (B) is formulated in admixture with at least one pharmaceutically ac¬ceptable auxiliary. A kit comprising the components: (A) a pharmaceutical formulation including an amount of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof, in admixture with at least one pharmaceutically acceptable auxiliary; (B) a pharmaceutical formulation including an amount of a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof, in admixture with at least one pharmaceutically acceptable auxiliary; wherein the first and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease. The combinations according to the invention can be used for the preventive or curative treatment of inflammatory pulmonary diseases, such as, for example, asthma, COPD, sclerosis, alveolitis, sarcoi¬dosis, idiopathic pulmonary fibrosis and pulmonary hypertension. Therefore, further aspects of the invention are: Combinabon of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof and a HMG-CoA reduc¬tase inhibitor or a pharmaceuticaliy acceptable salt thereof for use as a medicament. Combination of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof and a HMG-CoA reduc¬tase inhibitor or a pharmaceuticaliy acceptable salt thereof for the preventive or curative treatment of an inflammatory pulmonary disease. Pharmaceutical composition, combination product or kit, as described in the preceding paragraphs, for use as a medicament. Pharmaceutical composition, combination product or kit, as described in the preceding paragraphs, for the preventive or curative treatment of an inflammatory pulmonary disease. The use of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceuticaliy acceptable salt thereof for the manufacture of a medicament, in particu¬lar the pharmaceutical composition according to the invention, for the preventive or curative treatment of an inflammatory pulmonary disease. Another aspect of the present invention is the use of a PDE4 inhibitor or a pharmaceuticaliy accept¬able salt thereof and a HMG-CoA reductase inhibitor or a pharmaceuticaliy acceptable salt thereof for the manufacture of a sequential or separate co-administrable medicament, in particular the combina¬tion product or kit according to the invention, for the preventive or curative treatment of an inflamma¬tory pulmonary disease. Still another aspect of the present invention is a method for the preventive or curative treatment of an inflammatory pulmonary disease comprising administering to a patient in need thereof a pharmaceuti¬cal composition comprising a pharmaceutical formulation including an amount of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof, an amount of a HMG-CoA reductase inhibitor or a pharma¬ceuticaliy acceptable salt thereof, wherein the first amount and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease, and at least one pharmaceuticaliy acceptable auxiliary. A further aspect of the present invention is a method for the preventive or curative treatment of an inflammatory pulmonary disease comprising administering to a patient in need thereof a combination product comprising the components: (A) an amount of a PDE4 inhibitor or a pharmaceuticaliy acceptable sail thereof; (B) an amount of a HMG-CoA reductase inhibitor or a pharmaceuticaliy acceptable salt thereof; wherein the first and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease; wherein each of the components (A) and (B) is formulated in admixture with at least one pharmaceuti¬cally acceptable auxiliary; and wherein the components (A) and (B) are administered simultaneously, sequentially or separately. The pharmaceutical compositions according to the invention may be prepared by mixing the first ac¬tive agent with the second active agent. In the above-mentioned mixing process the first active agent and the second active agent can a) in a first step be mixed as such, afterwards be processed with at least one pharmaceutically ac¬ ceptable auxiliary and finally, for example, be pressed to tablets or caplets or b) in a first step separately be processed with at least one pharmaceutically acceptable auxiliary to give granules or pellets containing each only one of the two active agents; the pellets or granules for their part then can be mixed in an appropriate ratio and either pressed - optionally with further phar¬ maceutically acceptable auxiliaries - to give, for example tablets or caplets, or can be filled in loose form in capsules. Therefore, in a still further aspect of the present invention there is provided a process for the prepara¬tion of a pharmaceutical composition which comprises mixing a first active agent, which is a PDE4 inhibitor or a pharmaceutically acceptable salt thereof with a second active agent, which is a HMG CoA-reductase inhibitor or a pharmaceutically acceptable salt thereof. Simultaneous administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof can be preferably accomplished, by administering to the patient in need of inflammatory pulmonary disease therapy the pharmaceutical composition according to the invention in one dosage form, such as for example in a single capsule, tablet or injection. Components (A) and (B) of the combination product as well as of the kit may be administered sequen¬tially or separately over the course of the preventive or curative treatment of an inflammatory pulmo¬nary disease. Sequential or separate administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof can be preferably accomplished, by administering to the patient in need of inflammatory pulmonary disease therapy components (A) and (B) of the combination product or the kit according to the invention in (multiple) separate dosage forms, such as for example, in separate capsules, tablets or injections. The compo¬nents (A) and (B) of the combination product or the kit according to the invention can also be adminis¬tered simultaneously, for example by swallowing the two tablets containing the both active agents at the same time, or by using an inhaler system, which contains both active agents in separate contain¬ers, but deliver them together. In an alternative, one of the components (A) and (B) may be formulated as tablet or capsule and the other component may be formulated for administration, for example, by injection or inhalation. Sequential administration encompasses a short time period between the administration of components (A) and (B) of the combination product or the kit according to the invention (for example, the time that is needed to swallow one tablet after the other). Separate administration encompasses both relatively short and relatively long time periods between the administration of components (A) and (B) of the combination product or the kit according to the invention. However, for the purposes of the present invention at least one of the components is admin¬istered while the other component is still having an effect on the patient being treated. In a preferred embodiment of the invention the effect on the patient being treated is a synergistic effect. The combined administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof, either in form of the pharmaceutical composition, combination product or kit according to the invention, lead to an effective preventive or curative treatment of the inflammatory pulmonary disease, and in a preferred embodi¬ment is superior to the use of either active compound alone. Moreover, in a particularly preferred em¬bodiment, the combined administration of a PDE4 inhibitor or a pharmaceutically acceptable thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof shows a synergistic efficacy for treating an inflammatory pulmonary disease. As used herein, the term "synergistic" refers to the combination of a PDE4 inhibitor or a Pharmaceuti¬cally acceptable salt thereof with a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof either in form of the pharmaceutical composition, combination product or kit according to the invention having an efficacy for the preventive or curative treatment of an inflammatory pulmonary disease that is greater than would be expected from the sum of their individuals effects. The synergis¬tic effects of the embodiments of the present invention encompass additional unexpected advantages for the preventive or curative treatment of inflammatory pulmonary diseases. Such additional advan¬tages may include, but are not limited to, lowering the required dose of one or more of the active com¬pounds of the combination, reducing the side effects of one or more of the active compounds of the combination or rendering one or more of the active compounds more tolerable to the patient in need of an inflammatory pulmonary disease therapy. The combined administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof may also be useful for decreasing the required number of separate dosages, thus, potentially improving compliance of the patient in need of inflammatory pulmonary disease ther¬apy. The therapeutic effect of the combinations according to the invention may be also observed with re¬gard to the fast decline in lung function that is a hallmark of COPD, and effects may be observed re¬garding the systemic inflammation that is also a characteristic of COPD. The long-term effect of the combinations according to the invention will be the conservation of lung function and putatively less co-morbidity (based on effects on the systemic inflammation).

The exact dosage and regimen for administering a PDE4 inhibitor or a pharmaceutically acceptable salt thereof in combination with a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof will necessarily depend on the potency and duration of action of the active compounds used, the nature and severity of the inflammatory pulmonary disease to be treated, as well as the sex, age, weight, general health and individual responsiveness of the patient to be treated, and other relevant circumstances. As part of the combination therapy according to the invention the PDE4 inhibitor or a pharmaceutically acceptable salt thereof and the HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof are dosed in an order of magnitude customary for the mono-therapy, it more likely being pos¬sible, on account of the individual actions, which are mutually positively influencing and reinforcing, to reduce the respective doses on the combined administration of the PDE4 inhibitor or a pharmaceuti¬cally acceptable salt thereof and the HMG-CoA reductase inhibitor or a pharmaceutically acceptable saK thereof with the norm. Without intended to be limiting, the orally administered daily dosage (for an adult patient) of the PDE4 inhibitors or the pharmaceutically acceptable salts thereof will generally range from about 0.05 mg to about 200 mg; without intended to be limiting, the daily dosage (for an adult patient) of a PDE4 inhibi¬tor or a pharmaceutically acceptable salt thereof for administration by inhalation will generally range from 0.05 mg to about 100 mg. In the case of oral administration of 3-cyclopropylmethoxy-4-difluoromethoxy-N-(3,5-dichloropyrid-4-yl)benzamide (ROFLUMILAST) the daily dose (for an adult patient) for the mono-therapy is in the range from 50 to 1000 ug per day, preferably in the range of 50 to 500 ug per day, preferably by once daily administration. In the case of intravenous administration of 3-cyclopropylmethoxy-4-difluoro-methoxy-N-(3,5-dichloropyrid-4-yl)benzamide (ROFLUMILAST) the daily dose (for an adult patient) for the mono-therapy is in the range from 50 to 500 ug per day, preferably 150 to 300 ug per day. In the case of oral administration of CILOMILAST the daily dose (for an adult patient) for the mono¬therapy is likely to be in the range from 10 to 40 mg per day, preferably from 20 to 30 mg per day, preferably by twice daily administration. In the case of administration by inhalation of AWD-12-281 the daily dosage (for an adult patient) for the mono-therapy is likely to be in the range of 500 to 2000 pg per day. In the case of oral administration of LIRIMILAST the daily dosage (for an adult patient) for the mono¬therapy is likely to be in a range of 1 to 10 mg per day. In the case of oral administration of OGLEMfLAST the daily dosage (for an adult patient) for the mono¬therapy is likely to be in the range of 1 to 10 mg per day. In the case of oral administration of COMPOUND A the daily dosage (for an adult patient) for the mo¬notherapy is likely to be in a range of 0.1 to 10 mg once daily, preferably 0.1 to 2 mg once daily. The orally administered daily dosage (for an adult patient) of the HMG-CoA reductase inhibitors or the pharmaceutically acceptable salts thereof will generally range from about 0.01 mg to about 200 mg, preferably from 10 to 80 mg, more preferably from 5 to 40 mg; for administration by inhalation a dos¬age range of 0.001 mg to about 25 mg is preferred, even more preferable is a dosage from 0.1 to 25 mg.

THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED.

Technical Field
The present invention relates to the combination of certain known therapeutic compounds for thera¬peutic purposes. The substances used in the combinations according to the invention are known ac¬tive agents from the phosphodiesterase 4 (PDE4) inhibitor class and active agents from the HMG-CoA-reductase inhibitor class.
Background Art
Statins are widely used as cholesterol lowering therapeutic agents. They reduce cholesterol levels through competitive inhibition of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, the key enzyme that regulates cholesterol synthesis. The cholesterol-lowering effect of statins is also due to an increase in the uptake of cholesterol by cells as a result of intracellular cholesterol depletion and enhanced expression of low-density lipoprotein (LDL) receptors.
However, statins exhibit properties that are beyond their lipid-lowering effects. These non-lipid-lowe-ring properties involve the inhibition of the isoprenoid pathway including the cholesterol precursor me-valonate which is required as a precursor for the prenylation of a number of proteins leading to a change in function [Drugs of Today; 2004;40: 975-990]. For example simvastatin modulates chemo-kine and chemokine receptor expression by geranylgeranyl isoprenoid pathway in human endothelial cells and macrophages [Veillard NR et al; Simvastatin modulates chemokine and chemokine receptor expression by geranylgeranyl isoprenoid pathway in human endothelial cells and macrophages; Atherosclerosis; 2005 Nov 28; Epub ahead of print]. Statins also have a potential role as antioxidants leading to downregulation of inflammation [Drugs of Today; 2004; 40: 975-990J. Recent research data demonstrated that statins inhibit the induction of the major histocompatibility (MHC) class II expression by interferon-gamma (IFN-gamma), leading to repression of MHC ll-mediated T-cell activation. Fur¬thermore, statins inhibit the expression of specific cell surface receptors on monocytes, adhesion molecules and also integrin-dependent leucocyte adhesion [Timely Top Med Cardiovasc Dis; 2005; 9: E3]. Statins exhibit additional effects on inflammation by decreasing IL-6, IL-8, and MCP-1 synthesis in human vascular smooth muscle cells (VSMC) in vitro [Cardiovas Res; 2003; 59: 755-66]. Simvastatin inhibits growth factor expression and modulates profibrogenic markers in lung fibroblasts [Am J Respir Cell Mol Biol. 2005; 32: 290-300]. Furthermore, statins increase bioavailability of nitric oxide. Cerivas-tatin increased eNOS expression a NO release in human endothelial cells [J Physiol Pharmacol. 2002; 53:585-95], In vivo statins exert anti-inflammatory effects in many models of inflammatory airway dis-

eases like asthma and COPD. Simvastatin was shown to inhibit pulmonary inflammatory cell accumu¬lation and il_-4 and IL-5 release into the alveolar lumen after allergeH challenge in mice [J Immunol. 2004; 172: 2903-8]. Simvastatin inhibits cigarette smoking-induced emphysema and pulmonary hyper¬tension in rat lungs [Am J Respir Crit Care Med. 2005; 172: 987-93]. Overall statins exhibit inhibitory properties on inflammation and modulation on the immune system.
In the international patent application WOOO/48626 (University of Washington) aerosol compositions of HMG-CoA reductase inhibitors for inhibiting inflammation associated witn a pulmonary disease, such as asthma, interstitial pneumonitis, emphysema, chronic bronchitis, £dult respiratory distress syndro¬me (ARDS) and cystic fibrosis, are described. In EP1275388 (Takeda) several statins are described as useful for the treatment of TNFa associated diseases such as inflammatory diseases including asthma and COPD. In US20050119330 the use of HMG-CoA reductase inhibitors is descibed for the treatment of lung proliferative vascular disorders, such as for example pulmonary hypertension and pulmonary fibrosis.
There is pressing, need to improve the treatment of inflammatory puli710nary diseases like asthma and COPD. These inflammatory diseases are characterized by multifact Cyclic nucleotide phosphodiesterase (PDE) inhibitors, particularly innibitors of type 4 (PDE4), are use¬ful in the treatment of a variety of allergic and inflammatory diseases-for example in respiratory dis¬eases, such as asthma and chronic obstructive pulmonary disease.
HMG-CoA reductase inhibitors, by a route different from PDE4 inhibitors. are also useful in the treat¬ment of inflammatory diseases.
It would be desirable to provide combinations and methods of treatment that can take advantage of the different therapeutic pathways of a PDE4 inhibitor and a HMG-0>A reductase inhibitor to more effectively treat inflammatory disorders, in particular asthma and CO^D-
Description of the invention
It has now been found that the combined use of a PDE4 inhibitor an^ a HMG-CoA reductase inhibitor potentiates the anti-inflammatory effect of either component alone.
Therefore, according to a first aspect of the present invention there \0 provided a pharmaceutical com-

position comprising a pharmaceutical formulation including an amount of a PDE4 inhibitor or a phar¬maceutically acceptable salt thereof, an amount of a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof, wherein the first amount and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease, and at least one pharmaceutically acceptable auxiliary.
The above-mentioned pharmaceutical composition provides for the administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof with a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof and is thus presented as a single formulation.
Alternatively, the PDE4 inhibitor or a pharmaceutically acceptable salt thereof and the HMG-CoA re¬ductase inhibitor or a pharmaceutically acceptable salt thereof may be presented as separate formula¬tions, wherein at least one of those formulations comprises a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and at least one comprises a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof.
Thus, there is further provided:
A combination product comprising the components: (A) an amount of a PDE4 inhibitor or a pharma¬ceutically acceptable salt thereof; (B) an amount of a HMG-CoA reductase inhibitor or a pharmaceuti¬cally acceptable salt thereof; wherein the first and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease and wherein each of the components (A) and (B) is formulated in admixture with at least one pharmaceutically ac¬ceptable auxiliary.
A kit comprising the components: (A) a pharmaceutical formulation including an amount of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof, in admixture with at least one pharmaceutically acceptable auxiliary; (B) a pharmaceutical formulation including an amount of a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof, in admixture with at least one pharmaceutically acceptable auxiliary; wherein the first and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease.
The combinations according to the invention can be used for the preventive or curative treatment of inflammatory pulmonary diseases, such as, for example, asthma, COPD, sclerosis, alveolitis, sarcoi¬dosis, idiopathic pulmonary fibrosis and pulmonary hypertension.
Therefore, further aspects of the invention are:

Combinabon of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof and a HMG-CoA reduc¬tase inhibitor or a pharmaceuticaliy acceptable salt thereof for use as a medicament.
Combination of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof and a HMG-CoA reduc¬tase inhibitor or a pharmaceuticaliy acceptable salt thereof for the preventive or curative treatment of an inflammatory pulmonary disease.
Pharmaceutical composition, combination product or kit, as described in the preceding paragraphs, for use as a medicament.
Pharmaceutical composition, combination product or kit, as described in the preceding paragraphs, for the preventive or curative treatment of an inflammatory pulmonary disease.
The use of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceuticaliy acceptable salt thereof for the manufacture of a medicament, in particu¬lar the pharmaceutical composition according to the invention, for the preventive or curative treatment of an inflammatory pulmonary disease.
Another aspect of the present invention is the use of a PDE4 inhibitor or a pharmaceuticaliy accept¬able salt thereof and a HMG-CoA reductase inhibitor or a pharmaceuticaliy acceptable salt thereof for the manufacture of a sequential or separate co-administrable medicament, in particular the combina¬tion product or kit according to the invention, for the preventive or curative treatment of an inflamma¬tory pulmonary disease.
Still another aspect of the present invention is a method for the preventive or curative treatment of an inflammatory pulmonary disease comprising administering to a patient in need thereof a pharmaceuti¬cal composition comprising a pharmaceutical formulation including an amount of a PDE4 inhibitor or a pharmaceuticaliy acceptable salt thereof, an amount of a HMG-CoA reductase inhibitor or a pharma¬ceuticaliy acceptable salt thereof, wherein the first amount and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease, and at least one pharmaceuticaliy acceptable auxiliary.
A further aspect of the present invention is a method for the preventive or curative treatment of an inflammatory pulmonary disease comprising administering to a patient in need thereof a combination product comprising the components:
(A) an amount of a PDE4 inhibitor or a pharmaceuticaliy acceptable sail thereof;
(B) an amount of a HMG-CoA reductase inhibitor or a pharmaceuticaliy acceptable salt thereof; wherein the first and the second amount together comprise an effective amount for the preventive or curative treatment of an inflammatory pulmonary disease;

wherein each of the components (A) and (B) is formulated in admixture with at least one pharmaceuti¬cally acceptable auxiliary; and wherein the components (A) and (B) are administered simultaneously, sequentially or separately.
The pharmaceutical compositions according to the invention may be prepared by mixing the first ac¬tive agent with the second active agent.
In the above-mentioned mixing process the first active agent and the second active agent can
a) in a first step be mixed as such, afterwards be processed with at least one pharmaceutically ac¬
ceptable auxiliary and finally, for example, be pressed to tablets or caplets
or
b) in a first step separately be processed with at least one pharmaceutically acceptable auxiliary to
give granules or pellets containing each only one of the two active agents; the pellets or granules for
their part then can be mixed in an appropriate ratio and either pressed - optionally with further phar¬
maceutically acceptable auxiliaries - to give, for example tablets or caplets, or can be filled in loose
form in capsules.
Therefore, in a still further aspect of the present invention there is provided a process for the prepara¬tion of a pharmaceutical composition which comprises mixing a first active agent, which is a PDE4 inhibitor or a pharmaceutically acceptable salt thereof with a second active agent, which is a HMG CoA-reductase inhibitor or a pharmaceutically acceptable salt thereof.
Simultaneous administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof can be preferably accomplished, by administering to the patient in need of inflammatory pulmonary disease therapy the pharmaceutical composition according to the invention in one dosage form, such as for example in a single capsule, tablet or injection.
Components (A) and (B) of the combination product as well as of the kit may be administered sequen¬tially or separately over the course of the preventive or curative treatment of an inflammatory pulmo¬nary disease.
Sequential or separate administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof can be preferably accomplished, by administering to the patient in need of inflammatory pulmonary disease therapy components (A) and (B) of the combination product or the kit according to the invention in (multiple) separate dosage forms, such as for example, in separate capsules, tablets or injections. The compo¬nents (A) and (B) of the combination product or the kit according to the invention can also be adminis¬tered simultaneously, for example by swallowing the two tablets containing the both active agents at

the same time, or by using an inhaler system, which contains both active agents in separate contain¬ers, but deliver them together.
In an alternative, one of the components (A) and (B) may be formulated as tablet or capsule and the other component may be formulated for administration, for example, by injection or inhalation.
Sequential administration encompasses a short time period between the administration of components (A) and (B) of the combination product or the kit according to the invention (for example, the time that is needed to swallow one tablet after the other).
Separate administration encompasses both relatively short and relatively long time periods between the administration of components (A) and (B) of the combination product or the kit according to the invention. However, for the purposes of the present invention at least one of the components is admin¬istered while the other component is still having an effect on the patient being treated. In a preferred embodiment of the invention the effect on the patient being treated is a synergistic effect.
The combined administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof, either in form of the pharmaceutical composition, combination product or kit according to the invention, lead to an effective preventive or curative treatment of the inflammatory pulmonary disease, and in a preferred embodi¬ment is superior to the use of either active compound alone. Moreover, in a particularly preferred em¬bodiment, the combined administration of a PDE4 inhibitor or a pharmaceutically acceptable thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof shows a synergistic efficacy for treating an inflammatory pulmonary disease.
As used herein, the term "synergistic" refers to the combination of a PDE4 inhibitor or a Pharmaceuti¬cally acceptable salt thereof with a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof either in form of the pharmaceutical composition, combination product or kit according to the invention having an efficacy for the preventive or curative treatment of an inflammatory pulmonary disease that is greater than would be expected from the sum of their individuals effects. The synergis¬tic effects of the embodiments of the present invention encompass additional unexpected advantages for the preventive or curative treatment of inflammatory pulmonary diseases. Such additional advan¬tages may include, but are not limited to, lowering the required dose of one or more of the active com¬pounds of the combination, reducing the side effects of one or more of the active compounds of the combination or rendering one or more of the active compounds more tolerable to the patient in need of an inflammatory pulmonary disease therapy. The combined administration of a PDE4 inhibitor or a pharmaceutically acceptable salt thereof and a HMG-CoA reductase inhibitor or a pharmaceutically acceptable salt thereof may also be useful for decreasing the required number of separate dosages,

thus, potentially improving compliance of the patient in need of inflammatory pulmonary disease ther¬apy.
The therapeutic effect of the combinations according to the invention may be also observed with re¬gard to the fast decline in lung function that is a hallmark of COPD, and effects may be observed re¬garding the systemic inflammation that is also a characteristic of COPD. The long-term effect of the combinations according to the invention will be the conservation of lung function and putatively less co-morbidity (based on effects on the systemic inflammation).
The term "active compound" as used herein refers to a compound useful in the preventive or curative treatment of a disease.
The term "effective amount" as used herein refers to a therapeutically effective amount for treating an inflammatory pulmonary disease. In case of a combination therapy the term "effective amount" refers to the sum of the amounts of the combination partners, which is therapeutically effective for the pre¬ventive or curative treatment of an inflammatory pulmonary disease.
The term "patient" includes both humans and other mammals. In a preferred embodiment of the inven¬tion the term "patient" stands for humans.
The term "PDE4 inhibitor" as used herein refers to an active compound that is capable of reducing the physiological effect of the PDE4 isoenzyme of phosphodiesterase preferentially over other isoenzyme of phosphodiesterase.
