- Any clinically significant abnormal finding on screening biochemistry or haematology blood tests or urinalysis (see Appendix A and Appendix B)
- Any other significant disease, disorder or finding which may significantly increase the risk to the volunteer because of participation in the study, affect the ability of the volunteer to participate in the study or impair interpretation of the study data
