This is a quote from the article I found here, at physorg.com:
“The lung function data was really exciting,” Dr. Spiera said. “In patients with scleroderma, you usually see lung function tests getting worse over time, and if doctors try a therapy for a year and a patient doesn’t get any worse, we get pretty excited. What is amazing to me in this study is that we actually saw improvements in both lung function tests.”
This article is about tests using the cancer drug Gleevec. It is amazing that some drugs for another diseases is tested for something else. Take drugs against Raynaud’s, for instanse.
