Boehringer North AmericaProduces Nintedanib. FDA: Nintedanib with be tested in combination with 4050. 4050 will also be tested alone re: success rate of healing in patients with IPF. Please google Boehringer North America. There you will see they are posting (about 4 hours ago) the fact that they will be conductiong a large test in North America and elsewhere using nintedanib re IPF. I believe their tests will also include 4050. The numbers of people to be in the test and the locations of testing is very interesting. I do believe Prometic is being taken very seriously.....
