Any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product which does not necessarily have to have a causal relationship with this treatment. An adverse event can be any unfavorable and unintended sign symptom, or disease temporally associated with the use of a drug. This includes any newly occurring event that has increased in severity or frequency since the administration of the study treatment.
