Urban-training Intervention in Pulmonary Hypertension (UTHAP)
Study Purpose
Pulmonary rehabilitation is effective in the treatment of pulmonary hypertension (PH). However, the beneficial effects of such intervention have been seen to disappear over time in other chronic diseases. The objective of the project is to evaluate the efficacy of an urban exercise program after a rehabilitation program and to identify possible determinants of sustainability of the effect, both in patients and in a murine experimental model. Methodology: 1) Study in humans: randomized study (urban training) in 80 patients with PH. The main variable is the improvement in physical activity measured by accelerometry at 12 months. Improvements in bioimpedance and aerobic capacity will be analysed as secondary variables, as well as possible determinants of vascular function that guarantee the sustainability of the effect (pulse wave velocity, endothelial function, metabolic profile and other plasma biomarkers), and all of them will be correlated with the evolution of the disease (admission due to clinical deterioration). 2) Studies in a murine experimental model: Mice with pulmonary hypertension induced by the administration of SU5416 (sugen) and exposure to hypoxia for 3 weeks will be studied after a three-week rehabilitation program. Half of them will exercise 1-2 days a week for 4 more weeks. At the end of the program, the right ventricular pressure will be measured and subsequently the animals will be sacrificed. Morphometric studies will be performed on lung, cardiac and muscular tissue. Vascular endothelial function and autophagy will be also measured. The differences in these variables between the different experimental groups will be analysed.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial Details
Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT05523557 |
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
