oxygen therapy or room air, separated by a wash out period of 2 to 6 weeks.', 'detailedDescription': 'Rationale Oxygen therapy may be proposed to patients with cystic fibrosis (CF) with nocturnal hypoxemia but the indication and benefits of oxygen therapy have not been validated in CF.\n\nAim of the study and main objective The aim of the study is to evaluate the improvement in nocturnal hypoxemia by the measurement of nocturnal pulse oximetry (SpO2) after 6 weeks of nocturnal oxygen therapy in stable patients with CF.\n\nAn improvement is defined by a nocturnal SpO2 \\> 90% during the whole night.\n\nObjectives and secondary aims\n\n* Comparison of subjective sleep quality during oxygen therapy and room air after a period of 6 weeks by means of 4 validated sleep questionnaires\n* Comparison of quality of life during oxygen therapy and room air after a period of 6 weeks by means of a validated questionnaire for CF patients (CFQ).\n* Detection of the appearance or increase in nocturnal hypercapnia during oxygen therapy and room air after a period of 6 weeks\n* Comparison of a possible arterial pulmonary hypertension during oxygen therapy and room air after a period of 6 weeks by means of an echocardiography\n\nStudy design This is an open, multicentre, prospective, randomised and cross over study, comparing in individual patient two periods of 6 weeks: one period with nocturnal oxygen therapy and one period in room air, separated by a wash out period of 2 to 6 weeks.\n\nInclusion criteria\n\n* Children ≥ 6 years and adults ≥ 18 years with CF in a stable state\n* With a forced expiratory volume in one second (FEV1) ≤ 50% of predicted value\n* Having a pulse oximetry (SpO2) in room air ≤ 90% for ≥ 10% of the night and/or a SpO2 ≤ 90% for ≥ 10 minutes during the night\n* Any patient with prior noninvasive positive pressure ventilation (NPPV) but who has stopped NPPV at least 15 days before the start of the study.\n* Written approval by the patient and by the parents in case of a pediatric patient\n* Patient having the French social security coverage Non-inclusion criteria\n* Patients with a respiratory exacerbation during the last 15 days\n* Patients with NPPV or long term oxygen therapy prior to the start of the study and unable to stop this treatment\n* Impossibility of a medical examination\n* Pregnant patient or breastfeeding patient\n\nStudy protocol The study is proposed to the patients during the V0 visit, corresponding to the screening monitoring showing a nocturnal SpO2 in room air ≤ 90% for ≥ 10% of the night and/or a SpO2 ≤ 90% for ≥ 10 minutes during the night. After a period of 2 to 30 days, the written approval is obtained during a routine visit.\n\nThereafter, the patient will be randomised to receive either:\n\n1. nocturnal oxygen therapy with a stable flow to obtain a nocturnal SpO2 \\>90% (Oxygen period) while continuing his routine long term treatment\n2. his routine long term treatment without nocturnal oxygen therapy (Air period) During the Oxygen period, the oxygen flow will be at least 1.5 L/min. This flow may be increased up to 2L/min in case of the presence of nocturnal periods with a SpO2 ≤ 90%.\n\nThe two periods Oxygen and Air will be separated by a wash out period of 2 to 6 weeks to rule out any long lasting effect of nocturnal oxygen therapy.\n\nAt the end of the 2 periods of 6 weeks oxygen or air, the following investigations will be performed:\n\n* A nocturnal evaluation of gas exchange by the Sentec™ monitor (which measures SpO2 and transcutaneous carbon dioxide (PCO2)) and objective sleep quality by means of actigraphy\n* an evaluation of subjective sleep quality by means of 4 validates sleep questionnaires\n* an evaluation of quality of life by a validated CF questionnaire (CFQ)\n* spirometry with blood gases in room air\n* an echocardiography\n\nNumber of subjects Only 3 studies have evaluated the benefit of oxygen therapy on nocturnal gas exchange during one night and only one study has evaluated the benefit of oxygen therapy after a period of 26 months. This last study is limited by the small number of patients and the low compliance with oxygen therapy.\n\nNo study has evaluated the effect of oxygen therapy during a 6 weeks period. This limits the calculation of the number of subjects.\n\nAs the study is a cross over study, a number of 30 analysable patients is estimated to be sufficient for the evaluation of the primary outcome measure and the secondary outcomes. Because of the possibility of premature withdrawal, it is planned to include 50 patients.\n\nTotal duration of the study: maximum 22.5 months\n\nInclusion period: 18 months\n\nDuration of participation for one patient: maximum 4.5 months\n\nStatistical analysis and final report: 3 months\n\nNumber of participating centres: 8\n\nEstimation of the mean number of patients included per centre: 3 patients / 3 months / centre\n\nExpected results The results of the present study should help to define the criteria to start long term oxygen therapy and to assess the potential benefits of this treatment in stable patients with CF.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['CHILD', 'ADULT', 'OLDER_ADULT'], 'minimumAge': '6 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Children ≥ 6 years and adults ≥ 18 years with CF in a stable state\n* With a forced expiratory volume in one second (FEV1) ≤ 50% of predicted value\n* Having a pulse oximetry (SpO2) in room air ≤ 90% for ≥ 10% of the night and/or a SpO2 ≤ 90% for ≥ 10 minutes during the night\n* Any patient with prior noninvasive positive pressure ventilation (NPPV) but who has stopped NPPV at least 15 days before the start of the study.\n* Written approval by the patient and by the parents in case of a pediatric patient\n* Patient having the French social security coverage\n\nExclusion Criteria:\n\n* Patients with a respiratory exacerbation during the last 15 days\n* Patients with NPPV or long term oxygen therapy prior to the start of the study and unable to stop this treatment\n* Impossibility of a medical examination\n* Pregnant patient or breastfeeding patient'}, 'identificationModule': {'nctId': 'NCT01586728', 'acronym': 'MUCOXY', 'briefTitle': 'Oxygen Therapy in Cystic Fibrosis', 'organization': {'class': 'OTHER', 'fullName': 'Assistance Publique - Hôpitaux de Paris'}, 'officialTitle': 'Indication and Benefits of Nocturnal Oxygen Therapy in Cystic Fibrosis', 'orgStudyIdInfo': {'id': 'P 100801'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'OTHER', 'label': 'Air - oxygen', 'description': 'One period in room air and one period with nocturnal oxygen therapy, separated by a wash out period of 2 to 6 weeks.', 'interventionNames': ['Other: Air - oxygen']}, {'type': 'OTHER', 'label': 'Oxygen - Air', 'description': 'One period with nocturnal oxygen therapy and one period in room air, separated by a wash out period of 2 to 6 weeks.', 'interventionNames': ['Other: Oxygen - Air']}], 'interventions': [{'name': 'Air - oxygen', 'type': 'OTHER', 'description': '1. his routine long term treatment without nocturnal oxygen therapy during 6 weeks (air period)\n2. nocturnal oxygen therapy with a stable flow to obtain a nocturnal SpO2 \\> 90% (oxygen period) while continuing his routine long term treatment during 6 weeks.\n\nDuring the oxygen period, the oxygen flow will be at least 1.5l/min.
