Very smart on their part after waiting so many years and spending so much money on R-IT - don't make a mistake like CELG and their MS/ulcerative colitis drug - the more I have read about that fiasco the worse it gets - they missed detecting a drug metabolite that might be carcinogenic (or ignored it, but FDA didn't - so big a deal CELG didn't get a CRL, they got a refusal to file, total rejection of NDA) - can't get a bigger "oopsie" than that! Could be a 2-3 yr setback for Ozanimod, which was expected to deliver about $1.7B/yr.
