have no doubt in my mind, if a large, placebo-controlled Ph2b trial demonstrates unambiguous efficacy, that FDA will approve 2-73. Though the timeline is at least a year off, based on Macfarlane's 2019 estimate. Will take at least one year to enroll 300 pts., plus one year of treatment and data analysis. Though Ph2a was a different animal, it took 10 months (January to October) to enroll 32 participants.
