Number of Participants With Treatment-emergent Adverse Events (TEAEs) During the StudyFrom Baseline to the end of Safety Follow-up (approximately 6 weeks)An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Treatment-emergent AEs (TEAEs) were defined as those events that start on or after the time of first investigational medicinal product (IMP) administration, or whose severity worsens on or after the date of first administration of the IMP.

An adverse event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Treatment-emergent AEs (TEAEs) were defined as those events that start on or after the time of first investigational medicinal product (IMP) administration, or whose severity worsens on or after the date of first administration of the IMP.
