Filtering a file to table

I have a file that contains many logs :

Is there anyway to get a ride of these strings STR* and SMTGH* in order to get this output using awk / perl / script:

carl 1,10:00,14:00
applicaton,halfhour,onehours
theory,geo,programmation

carl 2,10:00,14:00
applicaton,nothing,nothing
theory,history,philosophy

david 1,10:00,14:00
applicaton,onehour,twohours
theory,nothing,nothing

david 2,10:00,14:00
applicaton,twohour,twohours
