Has the number of patients in cohort 2 been stated

Has the number of patients in cohort 2 been stated? Does anyone know if this will still be 3 patients, or will there be more? Regardless it is great to know that another round of folks will be getting dosed any time now, and at a significantly higher dosage. I wish these folks all the best and hope that this bigger dose really starts to kick p53 into high gear.
