Nelson, joining torrential with thanks for following and reporting.
In the past I used the SC method but due to large reactions developed initiating at the spots of injections I stopped using the SC method. (The study report a reaction defined as ecchymosis but I am not sure is the same).
Just going over the results I would like to mention one point: we must remember that the study has a goal, to support marketing authorisation of the new treatment based on sc of about 100 mg/w . And that some of the science we would be happy to know about the differences between SC and IM are missing or washed in the means and SD of data as reported. If both treatments were the same they would have designed the study differently to show same dose PK in comparisons. Just to mention that IM TE has Tmax much greater than 24h.
