Abstract
Description
[Technical Field]
[0001] This invention treats or prevents inflammation in the lungs by administering a high concentration of inhaled chelating agents. This invention relates to a method for preventing inflammation in the lungs, and to a formulation used in this method. The condition is associated with or caused by cystic fibrosis. [Background technology]
[0002] Cystic fibrosis is characterized by susceptibility to infections that cause inflammation and lung damage. Furthermore, inflammation and lung damage can also occur in the absence of bacterial infection (Sly et al., Am J). Respir Crit Care Med. 2009, Vol. 180 (No. 2): 146~ 52 pages).
[0003] Inflammation is the body's response to an invasion, which includes infections, trauma, and hypersensitivity. Inflammatory responses are complex and involve various mechanisms for defense against pathogens and tissue repair. (Lung) Inflammation is usually caused by pathogens, or by toxins, contaminants, irritants, and allergens. It is caused by exposure.
[0004] During inflammation, many types of inflammatory cells are activated. Each of these is involved in cytokines and signaling. They release substances that modify the activity of other inflammatory cells. The organization of these cells and molecules is This leads to the progression of inflammation. Clinically, acute inflammation can lead to pneumonia and acute respiratory distress syndrome (ARDS). While it is seen in diseases such as asthma, cystic fibrosis, and chronic obstructive inflammatory bowel disease, chronic inflammation is seen in asthma, cystic fibrosis, and chronic obstructive inflammatory bowel disease. It appears in diseases such as lung disease (COPD). The lungs are important organs for gas exchange, Excessive inflammation can be life-threatening. A delicate balance between inflammation and anti-inflammatory factors is crucial for the lungs. It is essential for homeostasis.
[0005] Immunity includes innate and adaptive systems. Innate immunity is nonspecific and is a response to pathogens. It triggers a rapid response, including inflammation, when faced with an invasion. Adaptive immunity is antigen-specific. This adaptive immunity first detects a specific antigen, and then mobilizes inflammatory cells to address that specific antigen. It targets specific antigens. The innate and adaptive systems share components and are able to withstand pathogens. They work together in a coordinated manner for defense.
[0006] The airway epithelium contains various substances, such as mucin, defensin, lysozyme, lactoferrin. They secrete substances such as nitric oxide, and these substances protect the respiratory system from microbial attack. It provides targeted protection. Epithelial cells also transmit several signaling molecules, such as reactive oxygen radicals. Itokines (TNF-α, IL-1β, granulocyte / macrophage colony-stimulating factor [GM]) -CSF) and other factors, as well as platelet-activating factors, attract inflammatory cells to the site of inflammation. Cytokines stimulate the release of arachidonic acid from membrane lipids, leading to the production of eicosanoids. This further stimulates mucus secretion due to goblet cell and tissue inflammation.
[0007] Surfactants are located on the surface of the alveoli and contain four types of surfactant proteins (SP A-D). They possess. Important for reducing tension on the lung surface is that these proteins form boundaries on the alveolar surface. It plays a crucial role in surfactant absorption. SP-A and SP-D also protect the host. They also participate in the process. These bind to bacterial surface molecules and modulate leukocyte activity, and pathogens It causes opsonization of the body.
[0008] IgA secreted by plasma cells forms an additional epithelial protective barrier, which prevents the attachment of microorganisms to the epithelial surface. IgA also binds to pathogenic bacteria, causing phagocytosis and antibody-dependent cell-mediated cytotoxicity. Immunoglobulin E (IgE) induces immediate-type hypersensitivity in the respiratory organs. IgE produces a vigorous reaction by binding to IgE receptors on the surfaces of mast cells, basophils, eosinophils, and B lymphocytes. Repeated exposure to the same antigen induces degranulation and the release of inflammatory mediators including histamine, prostaglandins,
[0009] leukotrienes, and tryptase. These increase vascular permeability, bronchoconstriction, and inflammatory cell infiltration. The iron chelating agent present in the formulation of US Patent Application Publication No. 2016 / 0263151 functions to provide a synergistic effect when
[0010] combined with acidified nitrite, enhancing the ability of the antibiotic to act. Current treatments for lung inflammation include oral or inhaled steroids and non-steroidal drugs that target the host's inflammatory response. However,
[0011] the action is temporary, requires continuous treatment, and has significant side effects.

[0032] [Figure 1]This figure shows that submicron particles of EDTA kill Pseudomonas aeruginosa biofilms and act synergistically with tobramycin in vitro. Pseudomonas aeruginosa biofilms in CF mucus were treated with aerosolized EDTA particles and / or tobramycin. The final concentration of tobramycin in droplets was 325 μg / ml. Figure 1A) Confocal microscopy image of the biofilm stained with BacLight LIVE / DEAD; Figure 1B) Bacterial count showing the quantitative effect of the treatment. [Figure 2] This figure shows that CaEDTA reduces the amount of bacteria in CF lungs more quickly than antibiotic treatment alone. Patients with CF were treated with spray-type CaEDTA (EDTA) or saline solution (placebo), and the amount of bacteria in sputum mucus was monitored (colony-forming units per gram of mucus). [Figure 3] Figure 3A shows the mean change in FEV1 (percentage points) over the entire 10-week period (4 weeks post-treatment) in patients treated with CaEDTA or placebo, starting from the beginning of treatment. Figure 3B shows the relationship between improvement in FEV1 (0-2 weeks) and body weight. [Figure 4] This figure shows the EDTA concentrations achieved in the sputum of three CF subjects 5 minutes and 2 hours after treatment with 75 mg of sprayable CaEDTA. [Figure 5] This study demonstrates that administration of high concentrations of chelating agents to mouse lungs reduces inflammation in the absence of infection. The total white blood cell counts are shown for bronchoalveolar lavage fluid (BALF) obtained from mice exposed to air or cigarette smoke (CS) and treated with intranasal administration of either vehicle or deferoxamine (DFO). As expected, cigarette smoke induces an increase in white blood cell counts, but DFO treatment significantly reduces this effect. [Figure 6]We have demonstrated that administration of high concentrations of chelating agents to the lungs of mice reduces inflammation in the absence of infection. The lung weights of mice exposed to air or CS and treated with vehicle or DFO as described above are shown. Since increased weight indicates more inflammation, lung weight can be used as a surrogate for inflammation. In CS-treated mice, lung weight increased significantly, as expected, while DFO treatment reduced average weight, suggesting reduced inflammation. [Figure 7] This study demonstrates that administering high concentrations of chelating agents to mouse lungs reduces inflammation in the absence of infection. CS increases BALF iron content, while treatment with deferoxamine reduces this effect. Left: Average iron content for each mouse group; Right: Scatter plot of the same data. [Modes for carrying out the invention]
[0033] [Methods of treatment or prevention] This invention treats inflammation in the lungs by administering a high concentration of inhaled chelating agents. ) or provide a method to prevent it.
[0034] Preferably, the high concentration of the inhaled chelating agent exceeds 37.5 mg / dose.
[0035] Preferably, the inhaled chelating agent is administered at concentrations exceeding 50 mg / dose.
[0036] It has been previously shown that inhaled EDTA alone does not treat bacterial infections (Bro wn et al. (Am J Dis Child, 1985, Vol. 139 (No. 8): pp. 836-839) );Hassett (Front Microbiol. 2016, vol. 7: p. 291) Brown et al. (1985) used a spray to treat children with chronic Pseudomonas aeruginosa infections. Sodium EDTA was used for 3 months, and no changes in lung function were observed. Concentration-dependent bronchoconstriction (Beasley et al. (Br Med J (Clin Res E)) d) In 1987, Volume 294 (No. 6581): pp. 1197-1198)) causing E Other studies have reported that DTA has no effect on FEV1 (Asmus et al., (J Allergy Clin Immunol. 2001, Vol. 107 (No. 1): 68~ (Page 72)) Therefore, chelating agents can affect, for example, cystic fibrosis (CF). asthma, chronic obstructive pulmonary disease (COPD), or other lung conditions that cause or are associated with inflammation. There is no basis for believing that it has any positive effect on things that are in that state. However, surprisingly, the present invention allows the inhaled chelating agent to treat or prevent pneumonia. They discovered that...
[0037] It is commonly believed that the lung environment of CF is acidic. However, CF lungs are the same as normal lungs. It has recently been shown that it has H (Schultz et al., "Airway sur face liquid pH in children with cystic fi "brosis," Nature Communications, 2017, Vol. 8 (Issue 1) (p. 1409). Therefore, current technologies using acidified nitrite, for example, US patents What is discussed in Patent Publication No. 2016 / 0263151, for example, is that the formulation is acid The conditioned state does not persist, but immediately returns to the normal lung pH of 7.4, thus in CF It is unlikely to work as a floor.
[0038] Although the acidity of the lungs in CF patients was normal, it was found that the iron levels were significantly different from those of normal lungs. Stites et al. (Am J Respir Crit Care Med. 19) In 1999, Volume 160 (Issue 3): pp. 796-798, the iron level in the lungs of CF patients was... Furthermore, it was shown that the levels of iron in the lungs of smokers were significantly higher compared to healthy individuals. The majority of the ferrous phosphate is in the form of ferrous iron, Fe(II), and it has been shown to correlate significantly with disease severity. (Hunter et al., MBio. 2013, Vol. 4 (No. 4): pp. 1-8). Daiichi Iron This generates highly reactive oxygen radicals that can severely damage tissues and DNA. It can participate in the Enton reaction (Jomova et al., Toxicology., 20 11, Volume 283 (Issue 2-3): Pages 65-87; MacNee, Eur J Pharm acol., 2001, Volume 429 (Nos. 1-3): Pages 195-207).
[0039] Without being constrained by theory, the method of the present invention (i) by chelation of zinc (ii) Inactivation of matrix metalloproteinases (MMPs), (ii) Chelation of iron Reduction of reactive oxygen species (ROS) production, and / or (iii) iron and zinc, etc. By reducing the amount of bacteria in the lungs by depriving bacteria of key ions, inflammation is reduced. It is thought that the action within individual lungs is one of the theorized ways in which inflammation is reduced. It may be any combination of these.
[0040] Inhalation is a localized method of administration, and therefore, it does not reach the target area, namely the lungs. It may be more effective in reaching its target and provides high and localized concentrations of inhaled chelating agents. Inhalation can be used to avoid undesirable side effects from systemic exposure to the active substance and to help the patient. This reduces the risk of developing resistance.
[0041] This invention treats or prevents inflammation in the lungs by administering a high concentration of inhaled chelating agents. A method of prevention, further providing a way in which the treatment or prevention of inflammation leads to an increase in FEV. do.
[0042] This invention treats or prevents inflammation in the lungs by administering a high concentration of inhaled chelating agents. A method of prevention is provided, further offering a method in which the treatment or prevention of inflammation is accompanied by a decrease in MMP activity. It is said that matrix metalloproteinases (MMPs) cause lung damage (Garr att et al., Eur Respir J. 2015, Vol. 46 (No. 2): pp. 384-384) and MMP activity is Zn 2+ Dependence on (Hazra et al., Molecular Vi sion, 2012; Vol. 18: pp. 1701-1711) is publicly known. However, in the lungs Previous attempts to target MMPs have been unsuccessful. This invention chelates zinc in the lungs. Inhaled chelating agents are used to reduce MMP-induced lung injury and treat or prevent inflammation. To prevent.
[0043] This invention treats or prevents inflammation in the lungs by administering a high concentration of inhaled chelating agents. A method of prevention in which the treatment or prevention of inflammation is accompanied by a reduction in the production of hydroxyl radicals. Further methods are provided. Since Fe catalyzes the formation of hydroxyl radicals, iron is used in lung damage. The main factors in (Stites et al., (Am J Respir Crit Ca re Med., 1999, Vol. 160 (No. 3): pp. 796-798. However, antioxidants The clinical trial has so far not shown any significant improvement in lung function. Akira used an inhaled chelating agent to chelate the iron in his lungs, and thus hydroxyl To reduce dikal-induced lung injury and treat or prevent inflammation.
[0044] This invention treats or treats infections in the lungs by administering a high concentration of inhaled chelating agents. A method of prevention, in which the treatment or prevention of inflammation is carried out by the presence of a chelating agent, and bacteria in the lungs Further provides methods resulting from the removal or reduction of biofilms generated by these processes. To reduce biofilms, bacteria and biofilms are removed through coughing and sputum. This will enable an increase.
[0045] This invention treats or prevents inflammation in the lungs by administering a high concentration of inhaled chelating agents. A method of prevention, where the treatment or prevention of inflammation stimulates local inflammation and causes local tissue damage. This can cause the removal of protease enzymes produced by bacteria, which can neutralize antibiotic activity. This further provides methods brought about by reduction. These enzymes are primarily cation-dependent. It is expected that removing cations from the environment will deactivate these enzymes. It can be done.

Some subjects may require a period of several days or several weeks. Higher doses or more frequent administrations in between, followed by lower doses or maintenance doses. The subject can benefit from the duration of "loading" the chelating agent. Since conditions like vascular disease and COPD are usually chronic, the target group is those who have been receiving such treatment for a long period of time. It is expected to be subject to legal action.
[0067] Regardless of the form of the drug formulation, the particle size is approximately 0.1 μm to 12 μm, or approximately 0.25 μm to 6 μm. Inhalation droplets, preferably in the range of 1 μm to 6 μm, more preferably in the range of about 2 μm to 4 μm. It is preferable to produce particles. Alternatively, the particles are 0.1 μm to 1.0 μm, 0.2 μm m~0.9μm, 0.3μm~0.8μm, 0.4μm~0.7μm, or 0.5μm This may be the case. By creating inhalable particles with a relatively narrow range of sizes, This will further increase the efficiency of drug delivery systems and improve the reproducibility of medication administration. It is possible. Therefore, the particles are 0.1 μm to 12 μm or 2 μm to 6 μm or approximately 3 to 4 μm. In addition to having a size in the range of m, the average particle size is within a narrow range, which is the target 80% or more of the particles delivered are within ±20% of the average particle size, preferably the average It is preferable that the particle diameter be within ±10%, more preferably ±5%, of the particle size. .
[0068] "Particle size" is a concept introduced to compare the dimensions of solid particles and liquid particles (droplets). For droplets and aerosols, the "aerodynamic diameter" and "aerodynamic mass center" are used. Terms such as "particle size diameter (MMAD)" are used. The definitions are given below.
[0069] "Aerodynamic diameter" is the diameter of a unit-density sphere having the same critical sedimentation velocity as the particle in question. Yes, it exists. It is used to predict where such particles will accumulate in the respiratory system.
[0070] The "aerodynamic median particle diameter" is the geometric mean aerodynamic diameter. (50% by weight) The particles in the 50% weight are smaller than those in the MMAD, while the particles in the 50% weight are larger.
[0071] During particle size measurement experiments, the suspension contains countless particles of different sizes that are in motion. When a particle size analyzer analyzes these particles, the particle size analyzer forms a particle distribution curve, The curve starts from the smallest particles, which can be as small as 1 nm, and goes up to the largest particles, which can be as small as 100 μm. It also encompasses the entire particle size range, including large particles. In the particle size distribution curve, the cumulative frequency is shown relative to the particle size.

[0136] Further features of the present invention are described more fully in the following non-limiting examples. These are included solely for the purpose of illustrating the present invention. This should not be understood as a limitation on Ming's extensive explanation.
[0137] [Example 1] For those who wish to treat or prevent lung infections by administering high concentrations of inhaled chelating agents. law Using suspension droplets of cystic fibrosis mucus collected from epithelial cell lines, a realistic in vi Biofilms were grown in the tro model (Haley et al., BMC Micro Biol, 2012, Vol. 12: p. 181). Pseudomonas aeruginosa clinical strains (MIC tobramycin > 2) Cultures at 56 μg / ml were prepared in M63 without a carbon source to mimic nutrient restriction. They were propagated and then transitioned to the late quiescent phase.
[0138] Suspend a few drops of mucus (5 μl) from an inverted IBIDI coverslip, and 10 3 Colony-forming units (CFUs) were inoculated, and then incubated in a humid environment at 35°C for 72 hours. We baited the film to generate a biofilm. Then, we sprayed droplets with tobramycin (2 Either 0 mg / ml, or aerosolized CaEDTA particles (10 mg / ml), or Both were treated for 5 minutes. The control was treated with a 50 / 50 solution of 0.9% physiological saline / water for spraying. After processing, the droplets were incubated for 16 hours, and then BacLight LIVE / Stained with DEAD (1 μl) and fixed with paraformaldehyde vapor for 30 minutes. Confocal microscopy was performed. We used a microscope to visualize the biofilm.
[0139] Figure 1A shows a thick cell with mostly viable cells (green) after treatment with saline spray. and exhibits a strong biofilm. As expected in resistant strains, tobramycin monotherapy is effective. The treatment in Germany has little effect on the survival rate. EDTA alone kills a certain amount (red It causes blood cells. The combination of tobramycin and EDTA is particularly biofil The majority of the cells have been killed. Figure 1B shows a quantitative representation of the microscopic image in Figure 1A. The control biofilm was 1 × 10 8The CFU / ml was EDTA-tobramycin. The treated biofilm was reduced by more than 6 orders of magnitude, and less than 10 2 The level was reduced to CFU / ml.
[0140] Patients with CF aged ≥ 6 years who were hospitalized due to exacerbation of symptoms were randomly selected and administered intravenously. In addition to these standard treatments with antibiotics and tobramycin spray, EDTA or physiological Administer saline solution (placebo). Administer EDTA together with tobramycin in 4 ml 50 ml doses. M CaNa2EDTA, 111mM Tris in 0.9% physiological saline, pH 7.1, for spraying. It was administered as a solution. After random selection, subjects were treated in the hospital for two weeks, during which time patients received daily treatment. Four treatments were administered (300 mg EDTA / day, or 3.3 mg EDTA / kg / day). Then, the patient was discharged and the treatment was continued twice a day for four weeks. The patient was then monitored for another four weeks. We monitored the data and set the total experimental time to 10 weeks.
[0141] Sputum was induced using 3% hypertonic saline for spraying at a rate of 8-10 L / min for ≥5 minutes. Before treatment Samples were collected and processed according to the relevant protocol at weeks 2, 6, and 10, and then stored at -80°C. It was stored. The mucus was separated from the clear sputum, and sputalysin (1 ml per gram of sputum) was added. Mix with ), vortex, incubate for 1 hour, then Skim Milk G The samples were placed in a lycerol storage medium and stored at -80°C.
[0142] The initial screening, followed by the third clinical examination (around 2 weeks later), the fifth clinical examination (6 weeks later), and finally a follow-up examination. During the follow-up investigation (10 weeks), sputum samples were obtained from the subjects' sputum. Mucus was separated from the clear sputum. Then, treat with Sputalysin (1 ml per gram of sputum) and Skim Milk Placed in a glycerol storage medium (1 ml / 100 mg mucus), and vortexed They were mixed and stored at -80°C.
[0143] Thaw the sample on ice and prepare serial dilutions from 10 to 7 times the original concentration, then prepare 20 μL of each dilution. The solution is cultured in three types of agar: McConkey (McC) agar or Blood agar (BA). The samples were placed on each plate. The plates were incubated at 35°C.
[0144] Species of the genus Pseudomonas are transparent or very pale pink on McC agar plates. Defined as lactose-negative colonies. Coarse-shaped colonies have a metallic sheen. Colonies with rough colony edges and a smooth morphology form regular colonies on McC agar. Colonies with a knee-like boundary, slow growth, and a mucous morphology are formed by the massive secretion of bacteria. It was surrounded by alginate.
[0145] The number of coarse colonies, smooth colonies, and mucilaginous colonies was measured over a 24-hour period. Count on both C agar and BA plates, and incubate the plates again for another 24 hours. The samples were then analyzed and counted to confirm each colony morphology. Ronnie was picked up and arranged in strips on a BA plate to obtain a pure culture.
[0146] Perform Gram staining to confirm that the isolate is Gram-negative and consists of rod-shaped cells. , and by rubbing a very small portion of the colony onto an oxidase test strip Further identification was performed by confirming the oxidase-positive state. Rapid development of dark blue This shows an oxidatively positive isolate.
[0147] Species of the genus Pseudomonas were identified by testing for resistance to the C390 antibiotic. The pure phosphate-buffered saline (PBS) was mixed with a McFarland density of 0.5. A suspension of the isolated strain is diffused on a nutrient agar (NA) plate, and antibiotic-impregnated d The disk was placed. After incubation at 35°C overnight, the area around the disk was cleaned. The absence of an inhibitory zone indicated resistance to antibiotics. Each of the confirmed Pseudomonas species present (likely P. aeruginosa) Pick up a single colony of the morphological type and resuspend it in a glycerol / serum storage medium. Stored at -80°C. Figure 2 shows Pseudomonas aeruginosa at 2 and 6 weeks. a) The change in colony count for (McC) is shown compared to the start of treatment. Two weeks after the treatment, the reduction in colony count was 4.5 times compared to the placebo group. The EDTA group showed a ratio of >400 times.
[0148] [Example 2] Treatment of pneumonia leads to a dose-dependent increase in FEV1. Subjects with CF ≥ 6 years of age who were hospitalized due to exacerbation of symptoms were randomly selected and administered intravenously. In addition to these standard treatments with antibiotics and tobramycin spray, EDTA or physiological Administer saline solution (placebo). Administer EDTA together with tobramycin in 4 ml 50 ml doses. A spray solution of M CaEDTA, 111 mM Tris in 0.9% physiological saline, pH 7.1 The drug was administered. After random selection, the subjects were treated in the hospital for two weeks, during which time the patients received the drug four times a day. The treatment was administered (300 mg of EDTA / day). After discharge, the treatment was continued twice a day for 4 weeks. The elephants were monitored for another four weeks, bringing the total experimental time to 10 weeks.
[0149] Lung function was measured by spirometry during the clinical examinations for each experiment. Of the three attempts, the best result was achieved. The data was recorded as is, and the results were expressed as a percentage of the predicted value.
[0150] Figure 3A shows the FEV1 levels for both groups at 2, 6, and 10 weeks after the start of treatment. This shows the average change. The average increase in FEV1 after 2 weeks was 16 points in the EDTA group. In contrast to the placebo group, the difference was 5 percentage points. This difference occurred after the completion of the treatment. The effect lasted for 4 weeks, with a 7 percentage point increase in the EDTA group compared to a 2 percentage point increase in the placebo group. There was an increase in intake. This demonstrates a clear improvement in lung function in the EDTA group. However, only slight changes were demonstrated in the placebo group. Figure 3B shows the EDTA group (R 2 =0 .70) shows an inverse correlation between FEV1 improvement and body weight, but Tobramais This shows that there is no correlation in the placebo group treated with than alone (R 2 (=0.01). This is because EDTA has a dose-dependent effect on lung function (mg EDTA / kg body weight). To indicate that.
[0151] Figure 4 shows that the delivery of 75 mg of CaEDTA to the lungs was 0.41–1.3 minutes after administration. This indicates that it results in a peak EDTA concentration of 4 mM.
[0152] [Example 3] Tobacco smoke-induced pneumonia is treated by administering high doses of chelating agents to the lungs. It is possible The effects of chelating agents on pneumonia were investigated in a mouse model of chronic obstructive pulmonary disease (COPD). It was tested. It is known that tobacco smoke (CS) induces pneumonia, and pneumonia is related to leukemia. This can be measured by an increase in sphere count and lung weight.
[0153] Male BALB / c mice (8 mice per group) were exposed to a specified dose of cigarette smoke (3 sticks) Tobacco, three times a day (Monday to Friday), or exposed to filtered room air for a period of two weeks. The mice were exposed to tobacco smoke 30-60 minutes before each exposure during the experiment. One dose of the iron chelating agent deferoxamine (DFO, 3.8 mg in 50 μl) or vehicle The nasal cavity was then treated. The mice were then sacrificed, and their airways and lungs were examined for tobacco smoke-induced inflammation. The effects on the elements and their concentrations were evaluated.
[0154] Bronchoalveolar lavage fluid (BALF) is collected (approximately 1 ml / mouse), and the lungs are surgically removed. Then, it was weighed. Equal amounts of trypan blue were mixed with BALF and Zeiss Axiosco Using a PE fluorescence microscope, counted manually with a standard Neubauer hemocytometer. The total number of viable cells in BALF was determined by laser ablation-induced coupling. Iron was measured by elemental analysis using plasma mass spectrometry (LA-ICP-MS), and publicly known The metal content was quantified by comparing it to the standard.
[0155] Figure 5 shows, as expected, that cigarette smoke significantly increases the total number of BALF leukocytes. This indicates that treatment with the iron chelating agent DFO significantly reduces this effect.
[0156] In line with this, Figure 6 shows that average lung weight increases significantly with treatment by cigarette smoke. Treatment at CFO has shown that this effect can be prevented.
[0157] As previously described, Stites et al. (Am J Respir Crit Car e Med. 1999, Vol. 160 (No. 3): pp. 796-798) describes the lungs and... The study showed that iron levels in the lungs of smokers are significantly higher compared to healthy individuals. Figure 7 (left) shows that average iron levels in BALF mice exposed to cigarette smoke were significantly reduced. It has been confirmed that the iron content increases, and that treatment with DFO reduces the average BALF iron content. 7 (right) shows that in 6 out of 7 mice treated with DFO (1 mouse was unrelated to the treatment). (Died for no apparent reason), BALF iron content was at the same level as that of mice exposed to air. This indicates that it was a lu.
[0158] [Virtual Example P1: High-dose dry powder chlorine for infection, inflammation, and oxidative stress] [In vivo experiments on the effects of the drug] Subjects with CF requiring treatment with dried tobramycin powder were divided into four cohorts. They will be assigned to receive 112 mg of dried powder twice a day for 28 days. In addition, Cohort 1 For patients (aged 18 and over), the increasing dose of dried CaEDTA powder (37.5 mg BID) is used. Administer 75 mg BID for 2 weeks, then 150 mg BID for 1 week. Patient T2 (>18 years old) received CaEDTA (37.5 mg BID for 1 week; 75 BI) Administer D for 2 weeks; 75 mg QID for 1 week. Cohort 3 (patients aged 12-18 years) This involves CaEDTA (37.5mg BID for 1 week; 75mg BID for 2 weeks, 150 Administer mg BID for 1 week. Finally, the observational cohort will receive tobramycin alone for 2 weeks. Administer for 8 days.
[0159] Sputum samples are collected weekly and evaluated for markers of infection and inflammation. Bacteria are isolated from the sputum colony. - Monitored by count. As a measure of structural damage, matrix metalloprotein The levels of tissue inhibitors of enzymes (MMPs) and metalloproteinases (TIMPs) Using latinzymography and immunoassay, respectively, previously described Measure as described (Gaggar et al., Eur Respir J. 2011, Vol. 38 (3 Issue): pp. 721-727; Garratt et al., Eur Respir J. 2015, Volume 46 (Issue 2): pp. 384-3894). The amount of iron in sputum is as previously described in ICP. -Quantify using MS (Hunter et al., Mbio. 2013, Vol. 4 (No. 4): pp. 1-8) ). Use an immunoassay to assess the amount of iron-binding protein. Myeloperoxida Neutrophil activity is also assayed as a measure of neutrophil inflammation, as previously described (G aggar et al., Eur Respir J. 2011, Vol. 38 (No. 3): 721-72. (Page 7). 3-Chlorotyrosine was measured as a biomarker for hypochlorous acid, a powerful oxidizing agent. Determine the level using stable isotope dilution gas chromatography with mass spectrometry. Measurement (Gaggar et al., Eur Respir J. 2011, Vol. 38 (No. 3): (Pages 721-727). Using a commercially available immunoassay kit, reactive oxygen species (ROS) Protein carbonyls are measured as an indicator (Gaggar et al., Eur Respir J. 2011, Vol. 38 (No. 3): pp. 721-727). Using immunoassays, As previously described, by measuring glutathione (GSSG and GSH) , assess oxidative stress (Kettle et al., Eur Respir J. 2014, Volume 44 (Issue 1): pp. 122-129. Inflammatory and oxidative stress markers (e.g., IL-8) Gene expression of IL-6 and TNFα is also monitored using nanostrings, and protein The quality is measured by ELISA. Oxidative stress can also be transmitted through metabolites, for example, malton Dialdehyde (molondialdehyde) (colorimetric assay) or 8-iso It can be measured using methods such as Plastan (ELISA). Iron is removed by laser-induced coupling. Elemental analysis is performed using plasma-intensity plasma-mass spectrometry (LA-ICP-MS).
[0160] This experiment showed a reduction in inflammatory markers in the EDTA group compared to the placebo group, and A decrease in iron levels is expected. This experiment will compare MMP and TIMP, especially M The change in balance between MP-9 and TIMP-1 (which is associated with the progression of bronchiectasis) Further demonstrations are expected.
[0161] This experiment compared the amount of bacteria in sputum in subjects treated with EDTA compared to control patients. Further reductions and increases in FEV1 are expected.
[0162] [Virtual Example P2: Effects of high-dose chelating agents on inflammation, lung injury, and oxidative stress] [In vitro experiment for use] Lung epithelial cells are grown in tissue culture and exposed to Fe(II) or excess oxygen. Induces inflammation. Cells are treated with CaEDTA (0, 1, 5, 10, 25, 50 mM) for 30 minutes. Process for 1, 3, 24, and 48 hours.
[0163] Immunoassays are used to test for inflammatory markers, such as IL-6, IL-8, and TNF- Monitor alpha, neutrophil elastase, and other changes. Reduced glutathione (GSH) By evaluating apoptosis based on oxidative stress levels and TUNEL assays, To measure treasury and toxicity, in this case both can be measured using commercially available assay kits, for example, The Glutathione Fluores from rmoFisher Scientific cent Detection Kit and BioVision Inc.'s TUNEL We use DNA Gragmentation Assay Kits, etc.
[0164] This experiment showed that inflammatory markers were more concentrated in EDTA-treated cells compared to controls. Substantial reduction; GSH is reduced (this is in EDTA-treated cells compared to the control). This indicates a reduction in reactive oxygen species; and measured by the TUNEL assay. In this case, apoptosis was reduced in EDTA-treated cells compared to the control. It is expected that this will be demonstrated.
[0165] [Virtual Example P3: High-dose chelate for spraying against inflammation, lung injury, and oxidative stress] [In vivo experiments on the effects of the drug] Subjects with CF ≥ 6 years of age who were hospitalized due to exacerbation of symptoms were randomly selected and administered intravenously. In addition to these usual treatments with antibiotics and spray tobramycin, spray EDTA Alternatively, administer physiological saline (placebo). EDTA should be administered together with tobramycin in a dose of 4 ml. 50 mM Ca EDTA, 111 mM Tris in 0.9% physiological saline, pH 7.1, for spraying. Administer as a solution.
[0166] After random selection, subjects will be treated in the hospital for two weeks, during which time they will receive treatment four times a day. (Up to 300 mg EDTA / day, or 3.3 mg EDTA / kg / day). Next, the subjects The patient will be discharged and the treatment will be continued twice a day for four weeks. The subject will be monitored for another four weeks, and the total experimental time will be measured. This should be done for 10 weeks. Induction should be performed with 3% hypertonic saline spray at a rate of 8-10 L / min for ≥ 5 minutes. Sputum is collected by doing so. Samples are collected before treatment and at weeks 2, 6 and 10, related Process according to the protocol and store at -80°C.
[0167] • Expression of inflammatory markers The collected sputum is stored in RNAlater®, and Qiagen RNEas Extract total RNA using y(registered trademark) or a similar extraction kit, and convert it to cDNA. Sivaneson et al. (Mol Microbiol, Vol. 79, pp. 1353-1366) As described in ), qPCR is used to monitor inflammatory markers and known hysteric acid Quantification compared to wool-keeping genes, such as actin and / or GAPDH. do.
[0168] This experiment compared the gene expression of inflammatory markers in the EDTA group compared to the placebo group. This is expected to show an average reduction.
[0169] • Cell damage, free iron, and oxidative stress The collected sputum was frozen without any processing, and as described above, the inflammatory markers were analyzed. As a measure of structural damage, matrix metalloproteinases (MMPs) and The levels of taloproteinase (TIMP) tissue inhibitors were measured using gelatin zymography. The immunoassays are used respectively and measured as previously described (Gagg ar et al., Eur RespirJ. 2011, Vol. 38 (No. 3): pp. 721-727; G arratt et al., Eur Respir J., 2015, Vol. 46 (No. 2): 384~ (Page 94). The amount of iron in the sputum is quantified by ICP-MS as previously described (Hu nter et al., MBio. 2013, Vol. 4 (No. 4): pp. 1-8). Immunoassay used. Then, the amount of iron-binding protein is evaluated. Using an immunoassay, as previously described... As mentioned, oxidative stress can be assessed by measuring glutathione (GSSG and GSH). Evaluate (Kettle et al., Eur Respir J. 2014, Vol. 44 (No. 1): (pp. 122-9).
[0170] This experiment showed a reduction in inflammatory markers in the EDTA group compared to the placebo group. This is expected. This experiment will examine the relationship between MMP and TIMP, particularly between MMP-9 and TIMP-1. It shows a change in the balance between (which is associated with the progression of bronchiectasis). Further predictions are expected.
[0171] [Virtual Example P4: High-dose chelating agent for inflammation, lung injury, and oxidative stress] [In vivo experiments for use] A single-center, randomized, double-blind, crossover study will be conducted targeting cystic fibrosis. Participants were randomized to receive either CaEDTA or saline solution (placebo) for two weeks. Extract. After this, a washout period and then other treatments for 2 weeks (EDTA or (Placebo) continues.
[0172] Monitor iron levels, inflammatory markers, MMP / TIMP, and FEV1 as described above. Yes. As previously mentioned, myeloperoxidase is used as a measure of neutrophil inflammation. Activity is also assayed (Gaggar et al., Eur Respir J. 2011, 3 Volume 8 (Issue 3): pp. 721-727). 3. As a biomarker for the powerful oxidizing agent hypochlorous acid. - Measure chlorotyrosine. Stable isotope dilution gas chromatography using mass spectrometry. - Use this to measure the level (Gaggar et al., Eur Respir J.2011) Year, Vol. 38 (No. 3): pp. 721-727). Using a commercially available immunoassay kit, Protein carbonyls are measured as an indicator of reactive oxygen species (ROS) (Gaggar et al., Eur Respir J. 2011, Vol. 38 (No. 3): pp. 721-727.
[0173] This experiment compared subjects treated with EDTA to a placebo in terms of iron and inflammation levels. Reduction in marker levels, changes in MMP / TIMP balance, and increase in average FEV1. It is expected that this will show an increase. This experiment will reduce myeloperoxidase activity and clo Further reductions in the average levels of rotyrosine and carbonyl are expected.
[0174] Clinical data demonstrate efficacy at 300 mg / day for two weeks. The same experiment... It has been demonstrated that 50 mg / day (75 mg BID) is beneficial for lung function and infections. (Figure 2 shows a decrease in bacterial count; Figure 3A shows an improvement in lung function.) Considering the improvement of a certain magnitude (average FEV1 of 16 percentage points), it will be understood by those skilled in the art. As assumed by the hypothetical example P1, a much lower dose, namely 75 There is a very high probability that mg / day (37.5 mg BID) will be effective.
[0175] Figure 4 shows that 30 minutes after a single dose of 75 mg of CaEDTA, the concentration inside the mucus plug was 1.34 mM. This indicates that EDTA is brought up to this point. The penetration of drugs such as tobramycin into CF sputum is It is significantly delayed (Kuhn, RJ (2001). Formula o f aerosolized therapeutics.Chest Volume 120, 94 (Pages S-98S), therefore, the concentration of EDTA in the airway surface fluid is substantially higher than in the center. It is publicly known that this is the most likely possibility. Therefore, the daily dose is 37.5 mg (clinical merit It is expected to show efficacy in fully intensified experiments (four times lower than the low dose with a positive result). This is reasonable. This is especially true for young patients who are administered at higher doses per unit of body weight. Furthermore, it generally shows a greater therapeutic effect at FEV1 (Figure 3B).
