Outcome Measures

Primary Outcome Measures :

1. Treatment-emergent adverse events (TEAEs) from Baseline to Safety Follow-up (SFU) in healthy Japanese study participants [ Time Frame: From Baseline until Safety Follow-up (up to Week 8) ]
   An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
