The first record for the trial in the clinicaltrials.gov database was 10/23/09, so we’re talking about 10 months in all to enroll 600 patients. That’s impressive, but not unduly so, IMO
The Ph iib (which is the piece that enrolled 570 patients) only started in early June - i.e. 570 patients in 2-3/4 months. FWIW.
