MedicalResearch.com: What is the background for this study? How does hyaluronan differ from other medications for COPD? Is it used for other medical conditions?
Response: Hyaluronan is a natural sugar found in the human body, including in the lung. We have found that when the lungs are exposed to pollution, this sugar breaks down, and the breakdown fragments cause inflammation in the lung. We also found that if we give back the natural form of hyaluronan, it protects the lung from inflammation. Patients suffering from COPD also have a lot of hyaluronan breakdown in their lungs. We therefore reasoned, that giving them back the natural form of hyaluronan, as an inhalation treatment, would help them reduce inflammation. We tested this, as a first step, in the treatment acute inflammation of the lungs in COPD patients who are suffering an exacerbation of their disease.
Hyaluronan is different from existing medications in that it is a natural product of the body. It is used in Europe for conditions like cystic fibrosis, and after sinus surgery to humidify the airways. Because it is given by inhalation, it acts locally in the lungs. (more…)
