RE:RE:Boehringer North AmericaThey do have FDA approval for IPF. The group test they referred to today is intended to target all types of lung fibrosis. IPF is one small unique segment of lung fibrosis. Boehringer thinks their approved IPF Drug Nintendab (spelling?) will also work on the many other kinds of lung fibrosis. Best to go to the Boehringer North America web page and read the announcement in full. There are a lot of interesting details that most likely pertain to Prometic 4050 as well....
