• History of any significant drug allergy or known or suspected hypersensitivity, to any component of the IMP.
• Participants having taken OPC-167832 within 30 days prior to screening.
• Participants having 5 half-lives or twice the duration of the biological effect, whichever is longer, of any IMP (inclusive of OPC-167832) within 30 days prior to screening.
• Participation in a clinical trial involving administration of 14C-labelled compound(s) within the last 12 months prior to screening.
• Any participant who, in the opinion of the investigator, should not participate in the trial.
