Let's look back at the unblinding time for B & P.

B-ABSSSI Phase 2b

9/16/2014 - Last patient visit
10/23/2014 - Top-line result
# of patients - 215
Unblinding rate - 215 patients / 37 days = 5.81 patients per day

P Phase 2a

3/17/2016 - Last patient visit
5/24/2016 - Top-line result
# of patients - 115
Unblinding rate - 115 patients / 68 days = 1.69 patients per day

Obviously it took B much faster to unblind than P. If we use B-ABSSSI's unblinding rate for B-OM,

# of unblinded patients - 42
Unblinding rate - 5.81 patients per day
Unblinding time - 7.23 days

If we use P's unblinding rate for B-OM,

# of unblinded patients - 42
Unblinding rate - 1.69 patients per day
Unblinding time - 24.85 days

I know every trial is different, but I expect B-OM to be unblinded in 25 days or less based on these numbers.
