RE:Feb 24, 2017 Pulmonary Fibrosis News IPF - ProMetic Nice find bio... Question to the smarter folks in here: if the purpose of this mini trial was to show efficacy of 4050, then why do you enrol 9 patients on 4050 alone, and 15 and 16 patients respectively on combo therapies with approved competing treatments? knowing that the smaller number of test subject patients decreases the accuracy and validity of your results, wouldn't one at least want to make the test groups an equal number? And if you are trying to tout 4050 as a standalone therapy, why have that many fewer patients in YOUR products test group?? Hell I'd have had 25 in the 4050 group to prove a point, either way. (I'd have also had a placebo group but that's another story for another trial).
