Definitions
- the invention is in the field of symptomatic treatment of cystic fibrosis.
- Cystic fibrosis (Cystic Fibrosis, CF) is an autosomal recessive genetic disorder caused by a mutation in the CFTR gene, a 250 kb gene that encodes a protein of 1480 amino acids called CFTR protein (Cystic Fibrosis, CF)
- This protein belongs to the family of chloride channels. To date more than 1000 mutations responsible for the disease have been described, but the most common, (discovered in 1989), called ⁇ F508, is present in about 70% of patients. This mutation consists of the deletion of an amino acid, a phenylalanine at position 508,
- Influenzae which can lead to an exacerbated inflammatory response in the airways, characterized by a massive influx of neutrophils. These pathogens are responsible for most episodes of bronchial infections. The lack of control of this inflammatory process, often associated with bronchial obstruction, causes destruction of lung tissue resulting in a gradual loss of respiratory function until death.
- This disease is also characterized by digestive disorders mainly due to exocrine pancreatic insufficiency present in 90% of patients. These respiratory and digestive manifestations dominate the clinical picture, but the respiratory compromise conditions the vital prognosis of the patients.
- mucoid character is virtually specific to the infection.
- the incidence of mucoid strains increases with age and the progression of respiratory disease. Bronchopulmonary involvement evolves by relapses which lead in a few months or several decades to chronic respiratory insufficiency. Complications such as recurrent pneumothorax or haemoptysis can make life worse.
- cystic fibrosis can only be treated symptomatically. Management is mainly based on respiratory physiotherapy and anti-infectious treatment with antibiotics. In addition to its heaviness, this treatment must be followed for life.
- Antibiotic therapy must comply with a certain number of binding general principles: appropriate choice of antibiotics, prevention of resistance due to the chronicity of bronchial infection, high doses over long periods of time (at least two weeks), only parenteral administration for antipyocyanic antibiotics.
- Molecules make it possible to thin the mucus and in particular rhDNase, catalytic enzyme of hydrolysis of the extracellular DNA which makes it possible to reduce the viscosity of the mucus then easier to evacuate by the physiotherapy.
- rhDNase catalytic enzyme of hydrolysis of the extracellular DNA which makes it possible to reduce the viscosity of the mucus then easier to evacuate by the physiotherapy.
- nocturnal oxygen therapy becomes necessary. But, lung transplantation is the last resort.
- cPLA2 cytosolic phospholipase A2
- AA is then metabolized by two distinct enzymatic pathways involved in inflammation: the cyclooxygenase (COX) pathway that results in the production of prostaglandins, particularly prostaglandin E2 (PGE2); and the lipooxygenase pathway that results in the production of leukotrienes, particularly leukotriene B4 (LTB4).
- COX cyclooxygenase
- PGE2 prostaglandin E2
- LTB4 leukotriene B4
- LTB4 leukotriene B4
- PGE2 prostaglandin E2
- CFTR mice '' ' stimulated by instillation with lipopolysaccharide (LPS) of Pseudomonas aeruginosa that causes inflammation of the airways secrete more mucus than wild mice.
- LPS lipopolysaccharide
- instillation is meant an administration by air, more specifically intratracheally.
- the inventors have also shown that this secretion of mucus is inhibited by aspirin, a COX inhibitor.
- Mucus is essentially mucins (glycoproteins) and MUC5AC is one of the most abundant mucins in the lungs of cystic fibrosis patients.
- the subject of the invention is the use of at least one inhibitor of cytosolic phospholipase A2 (cPLA2) in the preparation of a medicament for the symptomatic preventive and / or curative treatment of cystic fibrosis, particularly increased secretion of cystic fibrosis. mucus secretory epithelia of the respiratory and digestive mucous membranes.
- cPLA2 cytosolic phospholipase A2
- cPLA2 inhibitor any chemical or biological molecule, natural or synthetic, any composition which, whatever its mechanism, induces after administration a decrease, or even a complete inhibition, of the activity of the cPLA2 or the expression of the cPLA2 gene.
- cakA2 inhibitor ATK (Arachidonyl) may be mentioned as an inhibitor of cPLA2.
- the cPLA2 inhibitor is a siRNA that interferes with the expression of the cPLA2 gene.
- the inhibitor of cPLA2 used according to the invention is ATK.
- a combination of cPLA2 inhibitors (2 or more) in the preparation of a medicament for the treatment of diseases of the respiratory tract leading to a increased secretion of mucus, including the symptomatic treatment of cystic fibrosis.
- the cPLA2 inhibitor is used in the preparation a drug for the treatment of cystic fibrosis. It can also be envisaged that the cPLA2 inhibitor is used in the preparation of a medicament for the symptomatic treatment of increased mucus secretion in asthma, chronic obstructive pulmonary disease (COPD) such as laryngitis and pharyngitis, pneumonia, influenza, pneumoconiosis, chronic bronchitis and emphysema or aspergillary asthma.
- COPD chronic obstructive pulmonary disease
- the cPLA2 inhibitor may be used in the medicament in an amount of between 0.01 mg to 2 g, preferably from 1 mg to 1 g, very preferably from 10 mg to 500 mg.
- the inhibitor of cPLA2 such as, for example PATK
- the term "symptomatic treatment” refers to the preventive and / or curative treatment of symptoms related to the disease. This treatment also improves the management of patients (reduction of suffering, improvement of the lifespan, slowing of the progression of the disease etc.). The treatment may also be carried out in combination with other ingredients or treatments, such as in particular other active compounds for treating the pathologies or traumas specified in the present application.
- the subject of the invention is the use of at least one inhibitor of cytosolic phospholipase A2 (cPLA2) in the preparation of a medicament for the symptomatic treatment of the increased mucus secretion of cystic fibrosis said medicament to be administered in addition to gene therapy of cystic fibrosis.
- cPLA2 cytosolic phospholipase A2
- the drug according to the invention can take any conceivable form for its administration.
- it may be liquid as a syrup or solution for intramuscular injection or intravenous or solid such as a powder or a tablet.
- the administration can be carried out by any method known to those skilled in the art, preferably orally, aerosolized, or by injection, typically intraperitoneal, intra-cerebral, intrathecal, intravenous, intravenous. -arterial or intramuscular. Oral administration is preferred. As a long-term treatment, the preferred route of administration will be sublingual, oral or transcutaneous.
- the daily dose of cPLA2 inhibitor used according to the invention will be the minimum dose to obtain the desired therapeutic effect. This dose will depend on various factors such as the weight of the subject to be treated. If necessary, the daily dose may be administered in two, three, four, five, six or more doses taken daily or in multiple sub-doses administered at appropriate intervals during the day.
- the amount selected will depend on multiple factors, in particular the route of administration, the duration of administration, the timing of administration, the rate of elimination of the compound, the or various products used in combination with the compound, age, weight and physical condition of the patient, as well as his medical history, and other information known in medicine.
- the medicaments according to the invention may also comprise at least one other therapeutically active ingredient for simultaneous, separate or spread use over time, in particular during treatment in a subject suffering from a pathology as defined above.
- the medicaments according to the invention advantageously comprise one or more excipients or inert carriers, that is to say pharmaceutically inactive and non-toxic vehicles.
- the drugs may contain one or more agents or vehicles selected from dispersants, solubilizers, stabilizers, preservatives, etc.
- Agents or vehicles that can be used in formulations include methylcellulose, hydroxymethylcellulose, carboxymethylcellulose, cyclodextrins, polysorbate 80, mannitol, gelatin, lactose, vegetable oils or animal, acacia, etc.
- compositions may be formulated as injectable suspension, gels, oils, tablets, suppositories, powders, capsules, capsules, etc., optionally using dosage forms or devices providing sustained and / or delayed release.
- an agent such as cellulose, carbonates or starches is advantageously used.
- mice were tested for at least 5 mice per treatment category, 5-7 weeks old.
- mice and their wild homologs cPLA2 + / + , of the same genetic background were obtained from the "Department of Biochemistry and Molecular Biology, Faculty of Medicine, University of Tokyo” (Uozomi et al., Nature, 1997). These mice were 6-8 weeks old at the time of the experiment.
- P. aeruginosa LPS serotype 10 (Sigma, St. Louis, MO) EDTA, phenylmethylsulphoxide and dithiothreitol (Sigma, St. Louis, MO)
- Anti-MUC5AC antibody (clone 45 M1, Neomarkers, Fermont, CA, USA)
- Antibodies mouse IgG (Dako Cytomation Envision System). Amino Ethyl Carbazol (Sigma, St. Louis, MO).
- the products used were dissolved in saline solution (or physiological saline) and injected intratracheally (i.t.) or intraperitoneally (i.p.).
- the usage protocol was as follows:
- ATK (20 mg / kg, i.p.), 30 min before LPS and 24 h after.
- mice were anesthetized with 2% Xylazine (8 mg / kg) and Ketamine 1000 (40 mg / kg) prior to instillation of LPS (330 ⁇ g / kg, i.t.).
- mice were anesthetized with Pentobarbital (i.p.) at 200 mg / kg and their incised and cannulated tracheas.
- the LBAs were performed with successive washings with 1 ml of saline solution containing 5 mM EDTA and protease inhibitors (5 mM phenylmethylsulphoxide, 5 mM dithiothreitol).
- the counting of the cells was carried out by an automatic counter Counter ZM (Coultronic, Margency, France). This allows to highlight the state of inflammation of the lungs.
- Sections 5 ⁇ m thick were stained with Hemotoxylin / Eosin, periodic acid-Schiff (PAS) and Alcian blue (Alcian blue: AB, pH 2.4) according to standard methodologies (Normal and Pathological Histology).
- MLJ5AC (clone 45 M 1) for 2 h at room temperature, at a concentration of 8 ⁇ g / ml in 1X PBS.
- Mouse lungs were homogenized with lysis buffer (Quiagen RLT buffer). The homogenates were centrifuged, and equivalent amounts of proteins (10-50 ⁇ g) were deposited on the 7.5% electrophoresis gel (Tris / Glycine / SDS-polyacrylamide).
- the proteins were then transferred to a nitrocellulose membrane (Millipore) previously treated with PBS at 5% milk / Tween 1% o.
- the membrane was then incubated for 1 hour at room temperature in the presence of the primary antibody, then washed 3 times with PBS / Tween 1% o.
- the membrane was then incubated for 1 hour at room temperature in the presence of the secondary antibody, then washed with PBS / Tween 1% o.
- Actin control makes it possible to normalize the level of expression of the MU5AC protein.
- the intensity of the bands is measured with an image analyzer.
- Lung homogenates were prepared according to Filgueiras et al. (Lipids 22: 731-735, (1987)).
- the lipids were extracted by the method of Bligh and Dyer (Can.
- the spots corresponding to phosphatidylcholine (PC) were then recovered and their radioactivity measured using standard scintillation fluid.
- the cPLA2 activity was expressed in counts per minute (cpm).
- CF mice secrete more MUC5AC in LBAs both in baseline conditions than after LPS treatment compared with WT mice.
- mice received a dose of saline and a dose of aspirin.
- mice received a dose of saline and a dose of ATK.
- Table 4 The "control” mice received a dose of saline and a dose of ATK.
- mice received a dose of saline.
- the secondary antibody used is an anti-mouse IgG antibody (Dako Cytomation Envision System).
- the measurement of the quantity is related to the measurement of the amount of actin mRNA measured in the same sample for normalization (MUC5AC mRNA / Actin mRNA).
- the primary antibody used is an anti-cPLA2 monoclonal antibody (CeII Signaling or Santa Cruz).
- the secondary antibody used is an anti-mouse antibody (Dako Cytomation Envision System).
- the measurement of the quantity is related to the measurement of the amount of actin messenger RNA measured in the same sample for normalization (cPLA2 mRNA / Actin mRNA). Table 7
- Histological or immunohistochemical analyzes performed on sections of the lungs of mice, confirm the results obtained in the measurements of the mucus production by the cells of the bronchial epithelium.
