Active clinical trials for "Pulmonary Disease, Chronic Obstructive"

The investigators are studying the effect of a single dose Opioid drug (Morphine) on dyspnea and exercise tolerance in COPD patients.

Main adverse events of Roflumilast are weight loss, loss of appetite, insomnia, headache, diarrhea, vomiting, and nausea. Although the majority of these adverse reactions were mild or moderate. They occurred mainly at the beginning of therapy and mostly resolved with continued treatment around for two weeks according to experiences of clinicians. These adverse events occur more often in Roflumilast 500 μg than 250 μg, having negative impact on compliance of patients at the early stage of treatments. Thus, investigators aim to compare the drop-out rates between the usual dosage (Roflumilast 500 μg once daily) and the dose escalation (Roflumilast 250 μg once daily for 4 weeks and then escalating dose of 500 μg once daily).

The first-in-man study are designed as below to assess safety, tolerability, and preliminary pharmacokinetics of ZL-2102. Double-blind randomized, placebo-controlled ascending single oral doses (Part 1, ZL-2102-SAD); Open-label, randomized, 2-sequence, 2-period, 2-treatment crossover (Part 2, ZL-2102-FED); Double-blind randomized, placebo-controlled, ascending repeated oral doses for 14 days (Part 3, ZL-2102-MAD). A total of 104 subjects will be enrolled.

Chronic obstructive pulmonary disease (COPD) is characterized by the obstruction is not fully reversible airway, where the severity of the disease and the prognosis is not determined solely by changes in lung function. Pulmonary rehabilitation is a multidisciplinary program of care for patients with chronic respiratory diseases, individually designed to optimize physical and social performance and autonomy of these patients, promoting improvement in functional exercise capacity, quality of life, reducing dyspnea, frequency and duration of hospitalizations and reduce the frequency of exacerbations of the disease. The overall objective of the research is to evaluate the effects of pulmonary rehabilitation program on exercise capacity, lung function, quality of daily life and reduction of dyspnea in patients with COPD. A study type randomized, open-label trial following the recommendations of the CONSORT (Consolidated Standards of Reporting Trials) will be held. The study will be conducted at the Clinic Physiotherapy Course of the School with a sample of 58 patients. The intervention will be performed sessions three times a week for 16 weeks (8 weeks for assessment and 8 weeks for adaptation and (pulmonary rehabilitation training). The PR (pulmonary rehabilitation) will last 60-120 minutes each.O group A (control) will receive treatment of traditional pulmonary rehabilitation and without resistive training for upper limb (UL) and group B will receive the same treatment control with additional training of upper limb strength.

To compare the clinical outcomes of Endoscopic Lung Volume Reduction using Pulmonx Zephyr Endobronchial Valve (EBV) vs. Standard of Care (SoC) in the treatment of heterogeneous emphysema patients in a controlled trial design setting.

The primary purpose of this study is to show whether at home usage of the AIRVO warm humidifier can potentially reduce the number of exacerbations in patients with significant respiratory insufficiency. Eligible participants of the study must have a diagnosis of chronic obstructive pulmonary disease (COPD) stage II-IV..

Several impairing factors contribute to physical limitation in chronic obstructive pulmonary disease (COPD) as deconditioning, muscle dysfunction and physical inactivity. The available literature clearly indicates that these therapeutic targets benefit from exercise training in patients with COPD and, currently, the key point is not whether patients should or not exercise, but which is the specific contribution of each exercise modality to this population. About this topic, the characteristics of a physical training program to be offered to patients have been a point discussed among researchers in this field, although recently the high-intensity training has been recognized as superior in comparison to the low-intensity training. Literature also indicates that, in order to change the sedentary lifestyle of patients with COPD, long-term training programs are indicated. However, a doubt still remains: if long-term programs are one of the key points to reduce physical inactivity, it is not yet clear whether it is necessary to include high-intensity exercises in that long-term program. If the duration is the only factor influencing the outcomes of the program, thus the intensity of training could be reduced, increasing the adherence of patients to the protocol. Based on this hypothesis, the aim of this study is to compare the effects of two physical training protocols in a long-term rehabilitation program (6 months) in patients with COPD: a high-intensity protocol (based on endurance and resistive training) and a low-intensity protocol (based on callisthenic and breathing exercises training). It is expected that the results of this study contribute to the scientific literature by demonstrating whether low- and high-intensity training contribute equally to change the sedentary lifestyle of patients after a long-term exercise program.

We want to study the effect of the combination of metoprolol (a beta-blocker) with formoterol (a beta-agonist) on long function in patients with Chronic Obstructive Pulmonary Disease (COPD). There are more and more clues that a beta-blocker, when well chosen and in the right dosage, won't harm the long function in patients with COPD. Since a beta-blocker can be a valuable addition to treating patients with heart problems we would like to see if this category of medication can be available for COPD patients in the future.

Background: Despite recent recommendations for the inclusion of upper-limb endurance training in exercise training programs (ET) for patients with COPD, the majority of theses programs are yet focused only in lower-limb endurance training. However, these patients may have a hindered performance during the execution of simple activities of daily living (ADL) involving the upper-limbs. Therefore, one doubt remains: is the addition of upper-limb endurance training necessary? Aims: To verify whether patients with COPD become more physically active in daily life, as well as whether they improve ADL performance after two protocols of ET: 1) traditional ET (TET; endurance exercises of the lower-limbs and strengthening exercise for upper- and lower-limbs) and 2) TET + additional upper-limb endurance exercise (AULET). Methods: Patients with COPD (n= 64) will be included in this randomized controlled clinical trial. Before randomization to TET or AULET patients will be evaluated regarding physical activity in daily life (PADL; accelerometers), lung function (plethysmography), respiratory muscle strength (maximum ins- and expiratory pressures), body composition (bioelectrical impedance), performance in ADL (Londrina ADL protocol), maximum exercise capacity (symptom limited maximum test of lower and upper limbs), submaximal exercise capacity (endurance time at 80% of the maximum upper- and lower-limb capacity), functional exercise capacity (six-minute walk test and six-minute pegboard and ring test), peripheral muscle strength (one-repetition maximum test and dynamometry), healthy-related quality of life (Chronic Respiratory Questionnaire), health status (COPD assessment test), functional status (London Chest Activity of Daily Life scale) and symptoms of anxiety and depression (Hospital Anxiety and Depression Scale). Patients in both groups will exercise three times per week for 12 weeks. TET will be composed by endurance exercise for the lower-limbs (walking on treadmill and lower-limb cycling) plus strengthening exercises for upper- and lower limbs. Group AULET will perform the same exercises plus the additional upper-limb endurance training (upper-limb "cycling"). Patients will be evaluated by the same procedures after the ET. Hypothesis: The addition of upper-limb endurance training will increase PADL and ADL performance to a greater extent than the traditional exercise-training program alone due to greater reduction of physical activity-related dyspnea.

Bronchial basal cells are proved to be able to regenerate lung structures to repair the injured lung. In COPD patients, bronchus structures are injured and cannot be repaired, which may result in the failure of pulmonary function rescue clinically.In our research, autologous bronchial basal cells will be transplanted into lung of patients suffered with COPD to treat the disease. Specifically, autologous bronchial basal cells will be dissected from brushed-off samples by bronchofiberscope. Then, they will be expanded in vitro and transplanted into lung to regenerate new alveoli and bronchus structures and re-establish pulmonary system.
