Each participant will be supplied with a "study enrollment card" that will have the study title, along with the emergency contact information for the CHEO pharmacy technician (in control of study blinding) and for the Qualified Investigator (Principal Investigator—PI ). This card will act as a safeguard if the participant seeks emergency medical help where it is required to know whether they have been taking drug or placebo, thereby acting as an aid in the clinical judgment to stop the treatment. The enrollment card will also act to tract if/when a participant needs to be unblinded to the treatment.
