Ok, so there are many really intelligent people on this site and I need help. I am currently enrolled in the PTC 124 Ataluren study. My FEV1 is at 40% (on a really good day). So I have started the study and I really was wondering what all of these drugs are going to do for us? I understand the whole CFTR process.I understand the salt and water issue. I cannot understand how these drugs will help us. I thought that the drugs would stop the mucus production. That is the thing that is literally killing me. Every moment of everyday of my life my lungs are creating mucus and thus inflamation. I am assuming that if with these drugs there is improvement in the CFTR function then shouldnt that mean that the mucus should stop? I keep hearing of those on Vertex with incredible FEV1 improvements and that feel great. I am wondering exactely what is happening to their bodies? I also understand that we have damage that cannot be repaired but for these drugs to do their job they should stop the mucus which in turn will stop the inflamation and halt the disease process. Please those of you who understand this better please respond and educate me. I am looking for real answers because my educated guesses are not panning out. Much Love and Light!
