Abstract
The invention relates to the pharmaceutical use of specific substance P antagonists, in particular 1-acylpiperidine substance P antagonists, especially N-benzoyl-2-benzyl-4-(azanaphthoyl-amino)-piperidines, e.g. of formula
wherein X and Y are each independently of the other N and/or CH and the ring A is unsubstituted or mono- or poly-substituted by substituents selected from the group consisting of lower alkyl, lower alkoxy, halogen, nitro and trifluoromethyl; and pharmaceutically acceptable salts thereof for treatment of chronic fatigue syndrome (CFS) in the absence of serotonin agonist/selective serotonin reuptake inhibitory therapy, or for the treatment of fibromyalgia or associated functional symptoms.
Description
- This invention relates to substance P antagonists, in particular to 1-acylpiperidine substance P antagonists, and more specifically to new pharmaceuticals uses of such compounds.
- Substance P antagonists and their pharmaceutical use for treatment of gastrointestinal disorders, inflammatory disorders, central nervous system disorders and pain are described in, for instance, WO 90/05525, WO 91/09844 and WO 91/18899. 1-acylpiperidines and more particularly N-benzoyl-2-benzyl-4-azanaphthoyl-amino piperidines and their activities as substance P antagonists are described in European patent EP 0532456 B and published European patent application EP 0739892 A and European patent EP 0707006 B respectively. The disclosures of EP 0532456 B, EP 0707006 B and EP 0739892 A are incorporated by reference in the teaching of the present application.
- WO 96/24353 (Eli Lilly) descibes a method for the treatment and prevention of a psychiatric disorder in a mammal which comprises administering to a mammal in need thereof an effective amount of a combination of a tachykinin receptor antagonist and either a serotonin agonist or a selective serotonin reuptake inhibitor. Chronic fatigue syndrome is listed amongst the numerous psychiatric disorders which are identified as candidates for treatment by this method.
- Similarly WO 97/38692 (Eli Lilly) relates to a series of bisindoles which have activity both as tachykinin receptor antagonists and as serotonin agonists, and describes use of these bisindoles to treat migraine, pain or nociception, allergic rhinitis, the common cold, and a variety of psychiatric disorders including chronic fatigue syndrome amongst many others.
- Surprisingly it has now been found that substance P antagonists, in particular 1-acylpiperidines and especially N-benzoyl-2-benzyl-4-(azanaphthoyl-amino)piperidines, and pharmaceutically acceptable salts thereof are particularly useful for treatment of chronic fatigue syndrome in the absence of serotonin agonist/selective serotonin reuptake inhibitory therapy.
- Chronic fatigue disorders are a poorly defined clinical syndrome or combination of syndromes characterised by complaints of excessive fatigue and neurophysiological disturbances, often beginning after a viral infection. Attempts have been made to define diagnostic criteria for Chronic Fatigue Syndrome (CFS) but until recently the diagnosis has remained based on purely subjective criteria (Holmes et al. Annals of Internal Medicine 108: 387-389 (1988); Fukuda et al. Annals of Internal Medicine 121: 953-959 (1994)). In general, the fatigue is felt to be exacerbated following physical exertion, emotional stress, and/or viral illnesses. Lightheadedness, difficulty with thinking or concentrating, sleep disturbances, diffuse joint pain and tenderness, depression and weight fluctuations are often concurrent clinical features of chronic fatigue disorders. This general syndrome of chronic fatigue has also been designated CFS, neurasthenia, myalgic encephalomyelitis, fibromyalgia, post-viral syndrome, and chronic fatigue and immune dysfunction syndrome (CFIDS) (Price et al. Public Health Reports 107: 514-522 (1992)).
- Considerable uncertainty exists concerning the etiological basis of this constellation of symptoms. There are few consistent objective clinical findings in the disorder except that it is more prevalent in females than in males (Price et al. Public Health Reports 107: 514-522 (1992); Bou-Hlaigah et al. JAMA 274: 961-967 (1995)).
- Recently molecular genetic analysis has been applied to CFS (WO 98/37239-Glaxo) and it has been found that allelic variations within the arginine-vasopressin receptor-2 (AVPR2) gene are associated with variations in the clinical susceptibility to chronic fatigue disorders and this provides new methods for diagnosing CFS. These methods are described in WO 98/37239.
- Substance P antagonists for use in the invention for treatment of CFS are 1-acylpiperidines and more particularly N-benzoyl-2-benzyl-4-azanaphthoyl-amino piperidines; for instance as described in EP 0532456 B, EP 0707006 B and EP 0739892 A.
- Surprisingly it has also now been found that 1-acylpiperidine substance P antagonists, especially N-benzoyl-2-benzyl-4-(azanaphthoyl-amino)piperidines, and pharmaceutically acceptable salts thereof are particularly useful for treatment of fibromyalgia or associated finctional symptoms of fibromyalgia.
- Accordingly the present invention provides the use of a 1-acylpiperidine substance P antagonist, or a pharmaceutically acceptable salt thereof in the manufacture of a medicament for treatment of CFS, or fibromyalgia or associated functional symptoms of fibromyalgia.
- Fibromyalgia is a disease characterized by widespread muskulosceletal pain and tenderness on palpation at so called tenderpoints. The disease is diagnosed according to criteria as defined by the American College of Rheumatology (ACR) [see Arthritis and Rheumatism, Vol. 33, No. 2, pages 160-172, 1990]. In addition to pain symptoms, in the majority of fibromyalgia patients a variety of functional symptoms such as headache, insomnia, irritable bowel syndrome, sicca symptoms, increased sweating, dizziness, tremor, dyspnoea, arrhythmias, paraesthesias, headache/migraine, fatigue, psychopathological disorders and others occur. Therefore, the medical approaches towards management of fibromyalgia should not exclusively aim at relief of pain symptoms but also aim at improvements in functional symptoms.
- The present invention is to be understood as embracing the treatment of fibromyalgia as such, as well as pain and and/or functional symptoms associated with fibromyalgia either individually or collectively, e.g. use of 1-acylpiperidine substance P antagonists for treatment, e.g. the alleviation or amelioration of pain or any of the above mentioned symptoms as components of fibromyalgia. In addition to pain relief in fibromyalgia the present invention in particular provides for the treatment of the following functional symptoms as associated with fibromyalgia: including headache, insomnia, irritable bowel syndrome, sicca symptoms, increased sweating, dizziness, tremor, dyspnoea, arrhythmias, paraesthesias, headache/migraine, fatigue and psychopathological disorders.

- Unless otherwise defined, the general terms used hereinbefore and hereinafter have the meanings given in EP 0707006 B.
- The usefulness of the Preferred Compounds of the Invention, for treatment of Chronic Fatigue Syndrome (CFS) is demonstrated in the following clinical study.
- Patient Population
- Patients with chronic fatigue syndrome according to the CDC (Centre for Disease Control) definition (G. P. Holmes et al.: A working case definition. Ann. intern. Med; 108 (1988), 387-389) are included in the trial. Other recognised definitions may be used to identify patients with chronic fatigue syndrome as appropriate. Both male and female patients are eligible, provided they are over 18 years of age and under 65 years of age. The main exclusion criteria comprise pregnant and lactating women; in addition patients suffering from other diseases that cause significant fatigue as well as patients who suffer from active infections are excluded. Other exclusion criteria comprise severe rheumatological diseases, severe neuropathies, clinically manifest endocrinopathies, psychiatric diseases (including depression), fibromyalgia, and severe cardial, renal and hepatic impairment.
- The study is in the form of a prospective, randomized, double-blind, placebo-controlled, parallel-group study using different doses of a Preferred Compound of the Invention, (e.g. (2R,4S)-N-[1-(3,5-bistrifluoromethylbenzoyl)-2-(4-chlorobenzyl)-piperidin-4-yl-quinolin-4-carboxamide). Patients are randomly assigned to one of five study arms: placebo, 1 mg, 5 mg, 10 mg and 20 mg of test compound. (Preferably, for reliable evaluation of efficacy, each study arm includes 30 patients, giving a total sample size of 150 patients for the complete study.) The duration of treatment is four weeks. Before, on days 7, 14 and 21 and at the end of the treatment phase, a physical examination as well as assessment of fatigue and other symptoms are performed. Before study entry and at the end of the treatment blood tests are carried out. In order to document the daily intensity of fatigue, adverse events and concomitant medications, patients use a standardized diary and record daily the parameters mentioned. In addition, other symptoms as mentioned above, which are associated with CFS such as functional symptoms or cognitive impairment and myalgias are documented at start of treatment, and on days 7, 14, 21 and at the end of treatment. Adverse events are assessed during the active treatment period.
- Regarding changes in fatigue, a visual analog scale is used. This analog scale is represented by a 100-mm-line with one end (=0) indicating “no fatigue” and the other end (=100) indicating “worst fatigue”. Patients are asked to make a mark on the 100 mm scale which corresponds to their current fatigue intensity.
- Other parameters which are evaluated include cognitive impairment (to be measured by visual analog scale [VAS]) and the assessment of myalgias. In the latter case a VAS is also used for evaluation; for instance, as described above for assessment of fatigue, in addition to use of a pain score. The pain score allows an assessment of different body regions and ranges from 0 to 120, measuring the pain intensity in a total of 24 body regions. The following rating scale is applied: 0=no pain, 1=mild pain, 2=moderate pain, 3=moderately severe pain, 4=severe pain, 5=most severe pain. The assessment of each body region is done by the patients themselves; the total score is calculated as the sum of the regional scores.
- The following functional symptoms are evaluated in detail: cold hands/feet, sicca symptoms, increased sweating, dizziness, tremor, difficulties in falling asleep, difficulties in sleeping through, gastric problems, symptoms of irritable bowel syndrome, problems with swallowing, dyspnoea, aryythmias, paresthesias, painful micturation, haedache/migraine, and morning stiffness. For each of the symptoms mentioned, patients are asked to rate the presence of the symptoms according to a score ranging from 0 to 3 (0=not present, 1=slightly present, 2=moderately present, 3=strongly present).
- In addition to the documented effects during the active treatment phase, a follow-up of the patients is performed for six months in order to evaluate the duration of the clinical response (as defined by a 20% or higher reduction in any of the following symptoms: fatigue, myalgias, cognitive impairment; comparison of baseline vs end of treatment).
- Up to now there has been no standard or effective treatment for chronic fatigue syndrome. Thus it is proposed that a Compound of the Invention is considered as effective in treatment of CFS if one or more doses of the Compound leads to a response rate at least 10% higher as compared to placebo, wherein the response rate is the clinical response rate as defined above. The usefulness of the Preferred Compounds of the Invention for treatment of fibromyalgia or associated functional symptoms is demonstrated in the following clinical study.
- The study is in the form of a prospective, randomized, double-blind, placebo-controlled, parallel-group study using different doses of Compound of the Invention. Male and female patients (over 18 years) who meet the ACR (American College of Rheumatology) cirteria for primary fibromyalgia are included in this trial. The main exclusion criteria include pregnant and lactating woman, patients suffering from other inflammatory rheumatological diseases (such as rheumatoid arthritis or collagenoses), severe neuropathies, clinically manifest endocrinopathies, bone diseases, severe cardial, renal or hepatic impairment and acute or chronic infections.
- Patients are randomly assigned to one of five study arms, placebo, 1 mg, 10 mg, 20 mg and 40 mg of test compound. The duration of treatment is two weeks. Before, on day 7 and at the end of the treatment phase, a physical examination, pain assessment and blood testing are performed. In order to document daily the intensity of pain, adverse events and concomitant medications, patients use a standardized diary and record daily the parameters mentioned. In addition, changes in functional symptoms are documented at start of treatment, on day 7 and at the end of treatment. Adverse events are assessed during the active treatment period.
- To evaluate pain, the pain score, a visual analogue scale and clinical examination of tenderpoints is used. The pain score ranges from 0 to 120, measuring the pain intensity in 24 body regions applied to the following rating scale: 0=no pain, 1=mild pain, 2=moderate pain, 3=moderately severe pain, 4=severe pain, 5=most ever pain. The assessment of each body region is done by the patients themselves; the total score is calculated as the sum of the regional scores.
- The visual analogue scale is in the form of 100-mm-line oriented horizontally with one end=0, indicating “no pain” and the other end=100, indicating “worst pain”. The patients are asked to place a mark corresponding to their perception of their present pain intensity.
- In addition to the documented effects during the active treatment phase, a follow-up of the patients is performed for six months in order to evaluate the duration of the clinical response (as defined by a 35% or higher reduction in individual pain score/baseline versus end of treatment).
- Amitryptilin, an antidepressant drug, is regarded an effective treatment in fibromyalgia and leads to response rates of about 20 to 30% of patients.
- For use in accordance with the invention Preferred Compounds of the Invention most suitably are administered to human patients at a dose of about 1 to about 40 mg/kg per day. The Preferred Compounds of the Invention may be administered suitably in unit dosage form; for instance, in divided doses 1 to 5 times daily depending on the particular purpose of therapy, the phase of therapy and the like.
- Suitable dosage form for use in accordance with the invention include forms for enteral, for example oral, or parenteral administration. Thus, tablets or gelatin capsules which have the active substance together with diluents, for example lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and/or lubricants, for example diatomaceous earth, talc, stearic acid or salts thereof, such as magnesium or calcium stearate, and/or polyethylene glycol may be used. Tablets may likewise have binders, for example magnesium aluminium silicate, starches such as maize, wheat rice or arrowroot starch, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose and/or polyvinylpyrrolidone and, if required, disintegrants, for example starches, agar, alginic acid or a salt thereof, for example sodium alginate and/or effervescent mixtures, or absorbents, dyes, flavourings and sweeteners. It is furthermore possible for the Compounds of the Invention to be used in the form of products which can be administered parenterally or of infusion solutions. Solutions of this type are preferably isotonic aqueous solutions or suspensions, it being possible to prepare the latter, for example in the case of lyophilized products which comprise the active substance alone or together with an excipient, for example mannitol, before use. The pharmaceutical products can be sterilized and/or comprise ancillary substances, for example preservatives, stabilizers, wetting agents and/or emulsifiers, solubilizers, salts to control the osmotic pressure and/or buffers. The present pharmaceutical products which, if required, may comprise further pharmacologically active substance, are produced in an manner known per se, for example by conventional mixing, granulating, coating, dissolving or lyophilizing processes, and comprise from about 0.1% to 100%, in particular from about 1% to about 50%, lyophilizates up to about 100%, of the active substance.
