My Dad was diagnosed 8 years ago with Idiopathic Pulmonary Fibrosis. Unfortunately, he died this past May 26. Near the end his doctors were looking into some trials being conducted at Southwest Medical Center in Dallas, Texas. Since it was too late for us to try that route, I don't know anything else about it, but feel sure there is bound to be information available. God bless you and your husband. You will be in my prayers.
