So we need a total of 5 patients to file BTD, correct? And MIL counts as 1 of the 5 or do we need someone else? Also how much data do we need from the patients to be able to file BTD? I'm guessing about 5 weeks of data so if we can get one more patient by the 15th and then 5 weeks after that would put us at around the end of February beginning of March we could see BTD filed.
