 Study population [Design Issues]

Dear All,

According to the EMA GL CPMP/EWP/QWP/1401/98 Rev. 1/ Corr**London, 20 January 2010, "Subjects should preferably be non-smokers"

However, I have referred BE studies of Nicotine Replacements Therapy (NRT) Products (Gum, lozenges, microtab, mints etc) and noticed that only healthy-smokers had been used in NRT products BE studies.

My queries are:
  1. What is the rationale behind the selection of healthy smokers for BE studies of NRT products? ?
  2. Can we use healthy non-smokers for BE study of NRT products? Can we follow the GL only?
  3. Is there any regulatory compulsion for use of healthy smokers in BE study of NRT products? Specially EU.

Thanks and regards,

MMW

Hi mmw,

❝ According to the EMA GL[…] "Subjects should preferably be non-smokers"


Should preferrably be does not mean have to be, must be, etc.

❝ I have referred BE studies of Nicotine Replacements Therapy (NRT) […] and noticed that only healthy-smokers had been used in NRT products BE studies.


Yep. In all studies I have seen as well.

❝ 1. What is the rationale behind the selection of healthy smokers for BE studies of NRT products? ?


Smokers are addicted to nicotine and adapted to the effects/AEs. You don’t want to have a lot its AEs caused in non-smokers.

❝ 2. Can we use healthy non-smokers for BE study of NRT products? Can we follow the GL only?


I wouldn’t. The GL is not a law.

❝ 3. Is there any regulatory compulsion for use of healthy smokers in BE study of NRT products? Specially EU.


Not that I recall.
