Description
NEW COMBINATION OF ANTIASTHMA MEDICAMENTS
Field of the Invention The present invention relates to compositions and methods useful in the treatment of s respiratory disorders, particularly asthma.
Background of the Invention Despite recent advances in the awareness of asthma and the introduction of powerful and effective anti-asthma drugs, asthma remains a poorly understood and frequently poorly ~o treated disease. There have been recent advances in the treatment of the disease which result from the recognition that asthma is a chronic inflammatory disease.
Therapy is now aimed at both controlling the symptoms and reducing the inflammation. The symptoms include uncontrolled airway inflammation which may lead to mucosal damage and structural changes possibly leading to irreversible narrowing of the airways and fibrosis of ~ s the lungs.
The symptoms may be controlled by ~i2-adrenoreceptor agonists such as salbutamol, bambuterol, clenbuterol, fenoterol, procaterol, bitolterol, broxaterol, salmeterol, terbutaline and formoterol.
Prophylactic therapy is typically provided by steroids such as beclomethasone zo dipropionate (BDP), beclomethasone monopropionate (BMP), flunisolide, triamcinolone acetonide, dexamethasone, tipredane, ciclesonid, momethasone, RPR 106541, fluticasone or fluticasone propionate and budesonide or by way of sodium cromoglycate or nedocromil sodium.
Summary of the Invention The invention is based on the discovery that formeterol and rofleponide esters, or their salts or solvates, when administered to a patient either concurrently or sequentially, are unexpectedly effective in treating respiratory disorders involving inflammation, such as s asthma. Accordingly, the invention features a composition having, in an admixture: (a) a first active ingredient which is formoterol, a pharmaceutically acceptable salt or solvate of formoterol, or a solvate of such a salt; and (b) a second active ingredient which is rofleponide or a fatty acid ester of rofleponide.
It is preferred that the molar ratio of (a) to (b} is from 1:1 to 1:100, preferably from 1:1 ~o to 1:60, more preferably from 1:1 to 1:3~, and most preferably from 1:16.
The first active ingredient (a) of the composition can be, for example, formoterol ftunarate dihydrate, and the second active ingredient (b) of the composition can be, for example, rofleponide palmitate.
The composition can be provided in the form of a dry powder, the particles of which is may have a mass median diameter of less than 10~m.
The invention also includes a kit containing: (a) a vessel containing a first active ingredient that is formoterol, a pharmaceutically acceptable salt- or solvate thereof, or a solvate of such a salt; (b) a vessel containing a second active ingredient that is either rofleponide or a fatty acid ester of rofleponide; and (c) instructions for the sequential or 2o simultaneous administration of the first and second active ingredients to a patient in need thereof.
A patient suffering from a respiratory disorder such as asthma can be treated by administering (e.g., via inhalation), simultaneously or sequentially, (a) a dose of a first active ingredient selected from the group consisting of formoterol, a pharmaceutically is acceptable salt or solvate thereof, and a solvate of such a salt; and (b) a dose of a second active ingredient selected from the group consisting of rofleponide and a fatty acid ester of rofleponide. The active ingredients can be provided to the patient for inhalation in dry powder form.
When administered sequentially, the active ingredients can be administered in either 30 order, and within a two-hour time period. For example, the first active ingredient can be administered to the patient less than about 30 minutes after the second active ingredient, or the second active ingredient can be administered to the patient less than about 30 minutes after the first active ingredient.
Other features and advantages of the invention will be apparent from the following s description of the preferred embodiments thereof, and from the claims.
The combination according to the invention has the advantage that the toal dose of each active ingredient can be decreased and is more likely to provide patient compliance then would be extected from the properties of the individual active ingredients.
~o Detailed Description The invention provides a composition having (a) a first active ingredient selected from the group consisting of formoterol, a pharmaceutically acceptable salt or solvate of formoterol, and a solvate of such a salt; (b) a second active ingredient selected from the group consisting of rofleponide and a fatty acid ester of rofleponide; and, optionally, (c) ~s one or more pharmaceutically acceptable additives, diluents or carriers.
It has been found, using a sephadex-induced edema model (Kallstrom et al., Agents and Action 17:355-377 (1985)), that the combination of active ingredients provides a significantly enhanced anti-inflammatory effect compared to the sum of the individual anti-inflammatory effects of the two active ingredients, thus providing a significant advantage.
2o The first and second active ingredients of the composition can be administered simultaneously or sequentially to treat respiratory disorders. By simultaneous is meant that the first and second active ingredients (a) and (b) are administered concomitantly, for example as an admixture. Sequential administration generally comprises administering one immediately after the other. They still have the desired effect if they are administered 2s separately but not more than about two hours apart, for example no more than 30 minutes and preferably no more than 5 minutes apart.
Preferably the composition is administered to provide a daily dose of from 0.5 to 200 nmol (preferably from 4 to 100 nmol) of (a) and from 0.5 to 1140 nmol (preferably 14 to 285 nmol and more preferably from 14 to 285 nmol) of (b) 30 (subject to the molar ratio of (a) to (b) being from 1:1 to 1:100).
When (a) is fonnoterol fumarate dihydrate, the preferred daily dose is from 0.2 to 84 p.g (preferably from 2 to 42 p.g) of (a), and from 0.4 to 800 p.g (preferably from 10 to 400 p.g, more preferably from 10 to 200 p.g) of (b} where (b) is rofleponide palmitate (subject to the molar ratio of (a) to (b) being within the range of from 1:1 to 1:100).
Suitable physiologically acceptable salts of formoterol include acid addition salts derived from inorganic and organic acids, for example the chloride, bromide, sulphate, phosphate, maleate, fumarate, tartrate, citrate, benzoate, 4-methoxybenzoate, 2- or 4-hydroxybenzoate, 4-chlorobenzoate, p-toluenesulphonate, methanesulphonate, ascorbate, acetate, succinate, lactate, glutarate, gluconate, tricarballylate, hydroxynaphthalene-io carboxylate or oleate salts or solvates thereof. Active ingredient (a) is preferably formoterol fumarate, especially as the dihydrate.
Rofleponide is preferably esterified by a palmitoyl group.
Preferably each of the active ingredients comprises one or more pharmaceutically acceptable additives, diluents or carriers, more preferably in an amount of from 50 to 2000 ~s ~g in a daily dose, most preferably in an amount of from 100 to 1000 p.g.
Examples of suitable diluents or Garners include lactose, dextran, mannitol and glucose.
Preferably lactose is used.
Since active ingredient (b) is preferably a fatty acid ester, formulations containing it are desirably liposomal or proliposomal if they are dry powder formulations.
Suitable zo proliposomal formulations of fatty acid esters of rofleponide are described in WO
96/19199. For improved stability the formulation may comprise tocopherol, especially a-tocopherol.
Active ingredients (a) and (b) may optionally be formulated together to be administered simultaneously. For example, they may be formulated in admixture as a is proliposomal powder, for example of the general type described in WO
(preferably containing tocopherol as a stabilizing agent) or as an intimate mixture of {a) in the form of a dry powder and a proliposomal dry powder containing (b).
One or more of the active ingredients according to the invention are preferably in the form of a dry powder, more preferably a micronised dry powder, e.g. having a mass 3o median diameter of less than IOpm, for example from 1 to Spm, most preferably an agglomerated micronised dry powder. Alternatively active ingredient (a) may be in the form of an ordered mixture with ingredient (c). The ingredients used in the invention can be obtained in these preferred forms using methods known to those of skill in the art.
The invention further provides a method of treating a respiratory disorder, which is s preferably asthma, chronic obstructive pulmonary disease (COPD) and/or rhinitis, which method comprises applying to a patient suffering from, or liable to suffer from, such a disorder a therapeutically effective amount of a combination according to the invention.
According to the invention there is further provided the use of an admixture or kit according to the invention in the manufacture of a medicament for simultaneous, separate ~o or sequential use in therapy, preferably in the treatment of a respiratory disorder, e.g.
asthma, chronic obstructive pulmonary disease (COPD) and/or rhinitis.
Administration may be by inhalation orally or intranasally. The ingredients are preferably adapted to be administered from a dry powder inhaler.
The combination may optionally be administered as divided doses from 1 to 4, and ~s preferably once or twice a day, which means unit doses from 0.05 pg to 84 pg (preferably from 0.5 p,g to 42 fig) of formoterol fumarate dihydrate and from 0.1 ug to 800 ug (preferably from 2.5 ~g to 400 p.g) of rofleponide pahnitate.
Example 1 zo Rofleponide palmitate (IO parts by weight), dipalmitoylphosphatidylcholine (63 parts), dimyristoylphosphatidylcholine (24 parts), sodium dipalmitoylphosphatidylglycerol (3 parts) and racemic a-tocopherol (0.1 part) were dissolved in tertiary butanol (1300 parts) at 80°C. The solution was poured onto the shelves of a freeze-dryer cooled to -35°C. The solution had reached this temperature after about 30 minutes, the pressure in the freeze-zs dryer was then reduced in order to induce sublimation of the solvent. While the rate of sublimation could be adjusted by decreasing the pressure and increasing the temperature, the temperature throughtout the process was not allowed to exceed -10°C. Freeze-drying was continued until all the solvent had been removed. The resulting powder was scraped from the shelves of the freeze-dryer and passed through a sieve. This powder was 3o micronised in an air jet mill to a powder particle size of less than 5 Vim.
0.5 parts of formoterol fumarate dihydrate was mixed with 79.5 parts of lactose monohydrate. The blend was micronised using a high pressure air jet mill and then conditioned using the process of EP-A-717 616. This mixture (80 parts) was added to the steroid/lipid powder mixture (20 parts) by mixing and homogenising with a low pressure s jet mill. The mixture was then spheronised using the process of EP-A-721 331 and filled into a blister, a capsule or a storage chamber of an inhaler for use in a dry powder inhaler.
Other Embodiments It is to be understood that while the invention has been described in conjunction with io the detailed description thereof, the foregoing description is intended to illustrate and not limit the scope of the invention, which is defined by the scope of the appended claims.
Other aspects, advantages, and modifications are within the scope of the following claims.
