KMBJN, you should email Leo that comment by some bio president, I'm sure he would get a laugh from it:
He talks to biotech and pharma management quite a bit, and sent me a very brief note the other day that some antibiotic company's president told him "there is significant renal toxicity." I was very surprised and pointed him to links showing no such thing in 250+ patients in the two Phase II studies. So either the other antibiotic company's president is wrong out of ignorance (more likely), willfully spreading misinformation (possible?), or somehow correct (highly doubtful).
