- Concomitant medications GP verification of medical history: A medical history questionnaire will be sent to all participants' GPs for verification of medical history. This information will be reviewed by the Investigator as part of the medical history evaluation. If the completed questionnaire is not received from the GP, then the available information regarding the participant will be reviewed by the Investigator. The Investigator will assess this information and decide whether they are sufficiently confident that the inclusion and exclusion criteria are met and whether the participant may be enrolled into the study.
