Hey everyone,

Been looking at VRTX for awhile, and finally bit today. Doing my DD for sometime now, and fully admit I'm not an expert in this field, so I apologize for the lamen question upfront...

I noticed in the SGP PR (linked below for easy reference) that there are 595 patients. When I add up the denominators though in the "treatment arms" table, I come up with only 520 people. Now, I know ITT means anyone who took at least a single dose, so why does the data not add up to 595?? Where are the other 75 people? Did they just sign up, and not take a dose (my attempt at humor)?

Thanks!
