Definitions

  • the present application relates to novel pharmaceutical dosage forms containing potent and selective inhibitors of TASK-1 and / or TASK-3 channels and their use for the treatment and / or prevention of respiratory disorders, including sleep-disordered breathing disorders such as obstructive and central sleep apnea and snoring.
  • Potassium channels are nearly ubiquitous membrane proteins involved in a variety of different physiological processes. This includes the regulation of the membrane potential and the electrical excitability of neurons and muscle cells. Potassium channels are divided into three larger groups, which differ in the number of transmembrane domains (2, 4, or 6).
  • K2P channels two-pore domain K ".
  • the group of potassium channels in which two pore-forming domains are flanked by four transmembrane domains, are called K2P channels (two-pore domain K ").
  • the K2P channels largely mediate K + background currents, independent of time and voltage, and contribute significantly to their maintenance
  • the family of K2P channels comprises 15 members subdivided into six subfamilies based on similarities in sequence, structure, and function: TWIK (Tandem pore domain halothane inhibited K + channel), TREK (TWIK-related K + Channel), TIKK (TWIK-related acid-sensitive K + channel), TALK (TWIK-related alkaline pH activated K + channel), THIK (tandem pore domain halothane inhibited K + channel) and TRESK (TWIK-related spinal cord K + channel).
  • TASK-1 KCNK3 or K2P3.1
  • TASK-3 KCNK9 or K2P9.1
  • These channels are functionally characterized by the flow of so-called “leak” or “background” currents as they maintain the voltage-independent kinetics, thereby responding to a variety of physiological and pathological influences with an increase or decrease in activity.
  • Characteristic for TASK channels is the sensitive reaction to a change in the extracellular pH: the channels are inhibited at acidic pH and activated at an alkaline pH.
  • TASK-1 and TASK-3 channels play a role in the regulation of respiration. Both channels are expressed in respiratory neurons of the respiratory center in the brain stem, among others in neurons that generate the respiratory rhythm (ventral respiratory group with the pre-Bötzinger complex), and in the noradrenergic locus caeruleus as well as in serotonergic neurons of the raphe nuclei. Due to the pH dependence, the TASK channels here take on the function of a sensor that translates extracellular pH changes into corresponding cellular signals [Bayliss et al, Pflugers Arch. 467, 917-929 (2015)].
  • TASK-1 and TASK-3 are expressed.
  • TASK-1 knockout mice have been shown to have a decreased ventilatory response (increase in respiratory rate and tidal volume) to hypoxia and normoxic hypercapnia [Trapp et al, J. Neurosci. 28, 8844-8850 (2008)].
  • TASK-1 and TASK-3 channels in motor neurons of the hypoglossal nerve, the XII. Cranial nerve, which has an important function for the maintenance of the upper respiratory tract [Berg et al, J. Neurosci. 24, 6693-6702 (2004)].
  • a potassium channel blocker blocking the TASK-1 channel in the nanomolar range inhibited the collapse of the pharyngeal airway muscles and sensitized the negative pressure reflex of the upper respiratory tract.
  • Nasal administration of the potassium channel blocker is thought to depolarize mechanoreceptors in the upper respiratory tract, and activation of the negative pressure reflex results in increased upper airway muscle activity, stabilizing the upper airways and preventing collapse.
  • TASK channel blockade may be of major importance for obstructive sleep apnea and even snoring [Wirth et al, Sleep 36, 699-708 (2013); Kiper et al, Pflugers Arch. 467, 1081-1090 (2015)].
  • Obstructive sleep apnea is a sleep-disordered breathing disorder characterized by repeated episodes of upper airway obstruction. During inhalation, the patency of the upper respiratory tract is ensured by the interaction of two opposing forces. The dictating effects of the upper airway muscles counteract the negative intraluminal pressure that narrows the lumen. The active contraction of the diaphragm and other respiratory auxiliaries creates a negative pressure in the airways and thus provides the driving force for breathing. The stability of the upper airways is largely determined by the coordination and contraction properties of the dictating muscles of the upper respiratory tract. The genioglossus muscle plays a crucial role in the pathogenesis of OSA.
  • the activity of the genioglossus muscle increases with decreasing pressure in the pharynx in the sense of a dictating compensatory mechanism. Innervated by the hypoglossal nerve, it pulls the tongue forward and down, thereby expanding the pharyngeal airway [Verse et al, Somnologie 3, 14-20 (1999)].
  • the tension of the upper airway dictating muscles is modulated by, among others, nasopharyngeal mechanoreceptors / extensor receptors [Bouillette et al, J. Appl. Physiol. Respir. Environ. Exerc. Physiol. 46, 772-779 (1979)].
  • central sleep apnea episodic inhibition of the respiratory drive occurs as a result of disturbed brain function or disturbed respiratory regulation.
  • Central respiratory disorders lead to mechanical respiratory arrest, i. no respiratory activity takes place during these episodes, all respiratory muscles, including the diaphragm, temporarily stand still.
  • central sleep apnea there is no upper airway obstruction.
  • Obstructive snoring (upper airway resistance syndrome, heavy snoring, hypopnea syndrome) is caused by recurring partial upper airway obstruction during sleep. This leads to an increase of the airway resistance and thus to an increase in the work of breathing with considerable intrathoracic pressure fluctuations.
  • the negative intrathoracic pressure development during inspiration can reach values that occur as a result of complete airway obstruction in the OSA.
  • the pathophysiological effects on heart, circulatory system and sleep quality correspond to those in obstructive sleep apnea.
  • the pathogenesis, as in OSA is to be assumed in a disturbed reflex mechanism of the pharyngeal dilating muscles during sleep during inspiration.
  • Obstructive snoring is often the precursor to OSA [Hollandt et al., ENT 48, 628-634 (2000)].
  • a composition consisting of: 0.26% glycerol, 0.2% polysorbate 80, 0.9%> sodium chloride and 0.15%) potassium sorbate (without benzalkonium chloride) is used as Asonor ® for the treatment of snoring on the Market.
  • Asonor ® a nasal administration of Asonor ® compared to "Asonor ®" without polysorbate 80 in terms of an improvement of snoring was investigated.
  • Both Asonor ® and "Asonor ®” brought about without polysorbate 80 a significant improvement in snoring [Report from the Department of Neurology, University State Hospital, Copenhagen, Denmark.
  • EP 2595685 B1 (US Patent No. 9,132,243 B1) claims a pharmaceutical product comprising a container containing a liquid anti-snoring substance, the container containing a liquid outlet portion configured to directly insert the liquid anti-snoring substance into to deliver a nasal passage in the form of a jet stream.
  • the liquid anti-snoring substance is an anti-snoring solution comprising sodium chloride, glycerol, polysorbate and sodium edetate and optionally potassium sorbate as a preservative.
  • Apnea or OSA therapy is described in the originally filed application documents of EP 2595685 Bl and U.S. Pat. Patent No. 9,132,243 Bl not revealed.
  • the anti-snoring substance described is claimed for use in the treatment of snoring and respiratory arrest (apnea).
  • Novel substances that act as potent and selective inhibitors of TASK-1 and / or TASK-3 channels and, as such, in particular for the treatment and / or prevention of respiratory disorders, including sleep-disordered breathing such as obstructive and central sleep apnea and snoring, and others are known from PCT / EP2016 / 079973 and PCT / EP2016 / 079544 (unpublished).
  • the duration of action of the potent and selective inhibitors of TASK-1 and / or TASK-3 channels disclosed in EP 15199270.8 and EP 15199268.2 is not always sufficient in the case of nasal administration, which means a subsequent dosing during the night and thus an interruption of the night's sleep or of sleep is required.
  • the object of the present invention is therefore to provide an effective pharmacological therapy for the treatment and / or prevention of respiratory disorders, including sleep-related respiratory disorders such as obstructive and central sleep apnea and snoring, which is an alternative to treatment with the CPAP system.
  • Another object of the present invention is to increase the rate of compliance by a patient with treatment and / or prevention of respiratory disorders including sleep-related breathing disorders such as obstructive and central sleep apnea and snoring against the current standard of therapy (therapy of OSA: CPAP system).
  • this alternative therapy should be easy and convenient to use and not disturb the sleeping.
  • this alternative regimen of once-a-day dosing should allow for undisturbed sleep without re-medication.
  • a further object of the present invention is therefore to provide the pharmacologically active substances for the treatment and / or prevention of respiratory disorders, including sleep-related respiratory disorders such as obstructive and central sleep apnea and snoring in an application form suitable for once daily nasal or pharyngeal administration suitable for bedtime.
  • the extension of the duration of action of nasal administered drugs is difficult. Due to physiological conditions, the residence time of drugs, particles, capsules and the like on the epithelial cells is short.
  • the epithelium consists in part of ciliated cells, which have hair-like structures that contain cilia. These are covered by a mucous layer (mucus), which is transported away by a coordinated movement of the cilia in the direction of the throat. On the mucous layer, foreign particles and microorganisms remain attached after nasal uptake and are transported by the mucociliary clearance together with the mucus towards the pharynx and esophagus.
  • mucociliary clearance counteracts nasal absorption of drugs and, in particular, presents a challenge to achieving efficacy enhancement.
  • the flow rate of the mucus is approximately 5 mm per minute, so it is refreshed every 15-20 min. Cfearance half-lives of 15 min were therefore also determined for solutions and powders applied by nasal methods [Illum et al., Int J Pharm. 39, 189-199 (1987)], so that in principle the active ingredients linger only briefly on the mucosa in order to have an effect achieve.
  • One method to achieve nasal application prolongation is to extend the contact time between the drug and the site of absorption in the nose, the epithelial cells. Prolonged contact time increases the absorption of drugs in the nose.
  • the active ingredient intake can take place over a relatively long period of time, so that, on the one hand, a prolonged action or duration of action can be achieved and, on the other hand, the total amount of drug taken up can be increased.
  • Methods to increase the contact time between the drug and the epithelial cells Increases in viscosity include the use of bioadhesive polymers or the use of microparticles.
  • Pennington et al. were able to show as early as 1988 that by increasing the viscosity of nasally applied solutions with hydroxypropylmethylcellulose, the clearance rate is reduced [Pennington et al, Int J Pharm. 43, 221-224 (1988)]. With increasing polymer content and thus increasing viscosity, the half-life of 1 hour to 2.2 hours extended. Compared with those of lllum et al. [Illum et al, Int J Pharm. 39, 189-199 (1987)] for 15 min. Solutions, the increase in viscosity thus resulted in a marked increase in the half-life.
  • viscous solutions and semi-solid systems such as gels, creams and ointments are more difficult to apply than low-viscosity formulations. Atomization via a spray is no longer possible and precise metering with applicators in the case of semi-solid systems is more difficult.
  • nasally-applied semi-solid systems can lead to blockage that can interfere with nasal breathing.
  • in situ gels is also conceivable [Majithiya et al., AAPS PharmSciTech 7 (3), Article 67 (2006)].
  • the gelation is triggered only within the nose, z. Example by a change in temperature, a change in the pH or the presence of ions.
  • Chitosan As bioadhesive polymers, starch and chitosan are frequently used [Illum et al, J Controlled Release 87, 187-198 (2003)]. Chitosan is a bioadhesive polysaccharide and can interact well with the epithelial cells and mucosal layer. This produces a longer contact time available for drug delivery across the membrane. Chitosan is widely used in the literature, but these are mainly in vitro experiments. To date, chitosan has not been approved for nasal application (FDA Drag Databases, Inactive Ingredient Search for Approved Drag Products) and the potential long-term toxicity for chronic nasal application has not been fully investigated.
  • FDA Drag Databases Inactive Ingredient Search for Approved Drag Products
  • the encapsulation of the active ingredient in polymeric microparticles is [Cerchiara et al, Eur J Pharm Biopharm. 61, 195-200 (2005)].
  • the active ingredient is embedded in a suitable polymer which has a low solubility in water, or a polymer combination which additionally allows adhesion of the active ingredient-laden microparticles to the nasal mucous membrane.
  • the active ingredient is released from the microparticles depending on the nature of the polymer used by diffusion and / or polymer degradation / erosion delayed, resulting in a prolonged duration of action of the drug at the site of action.
  • the polymer combination used, from which the microparticles are composed additionally has the property of adhering to the nasal mucous membrane, then an extended residence time and thus duration of action of the nasally introduced medication can be expected.
  • the combination of microparticles and bioadhesive polymers is therefore a much-described approach for extending the duration of action in nasal administration, since two principles - the delayed release and the increase in contact time - are combined.
  • the microparticles can be prepared directly from a bioadhesive polymer [Illum et al, Int J Pharm.
  • prolongation of drug release may also be produced by the use of suspended rather than dissolved drug.
  • the active ingredient used is z. B. micronized (comminution to drug microparticles) and incorporated into a liquid phase (suspended). After application to the nose, the active ingredient particles dissolve at the site of action delayed. Only the dissolved drug can be absorbed through the nasal mucosa and then become effective.
  • the dissolution kinetics which determines the prolongation of the effect, depends i.a. from the physicochemical properties (eg solubility, particle size) of the active ingredient used.
  • crystal suspensions and polymeric microparticles require a large number of successive process steps which significantly influence the quality of the finished dosage form.
  • the Functionality of these complex forms of administration can be adversely affected due to lack of storage stability.
  • crystal suspensions have particle sedimentation (including sedimentation) and / or changes in primary particle size during storage, resulting in inhomogeneity within the dosage form and thus misdosing.
  • the preparation of crystal suspensions and polymeric microparticles requires the use of numerous stabilizers and polymeric matrix formers which, after nasal administration, can lead to local incompatibilities / irritations.
  • particulate systems such as crystal suspensions and polymeric microparticles, which are associated with a delayed release and dissolution of the active ingredient, lead to the fact that due to the mucociliary clearance, a non-reproducible portion of the dose before absorption already removed as undissolved particles and is swallowed.
  • ingestion of active ingredient can lead to high variability of exposure [Malinovsky et al., Br J Anesthesia 77, 203-207 (1996)].
  • crystal suspensions and polymeric microparticles are associated with more complex instructions for use, which can lead to application errors, which in turn endanger the desired therapeutic success.

  • German country pigs were used for the model. Since the nasal axis is in an almost vertical position in humans in a lying, sleeping position, the pigs became attached Fixed the experiments in a sitting position (70 degrees) with the nose pointing upwards. As a result, after nasal administration, the formulation flowed down all areas of the upper respiratory tract. The pigs were anesthetized and tracheotomized. In each of the rostral and caudal parts of the trachea a cannula was inserted. The rostral cannula was connected by means of a T-piece on the one hand to a device which generates negative pressure, and on the other hand to the caudal cannula.
