Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) up to Week 52
时间窗: Up to Week 52
An AE is any untoward medical occurrence in a clinical study participant administered a medicinal product and which does not necessarily have a causal relationship with that product. An SAE is defined as any untoward medical occurrence that, at any dose, meets one or more of the criteria listed: results in death, is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect in the offspring of a study participant; or other situations as per the medical or scientific judgment of the Investigator.
Number of Participants with Adverse Events of Medical Interest (AEMIs) up to Week 52
时间窗: Up to Week 52
An AEMI is an event of scientific and medical concern specific to the Sponsor's product or program, for which ongoing monitoring is appropriate. The following are AEMIs for this study: taste disturbance, oral hypoesthesia, oral paresthesia, and new or worsening findings of the cornea.
Number of Participants with Study Treatment Discontinuation due to AEs and SAEs up to Week 52
时间窗: Up to Week 52
An AE is any untoward medical occurrence in a clinical study participant administered a medicinal product and which does not necessarily have a causal relationship with that product. An SAE is defined as any untoward medical occurrence that, at any dose, meets one or more of the criteria listed: results in death, is life-threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect in the offspring of a study participant; or other situations as per the medical or scientific judgment of the Investigator.
Number of Participants with AEs and SAEs Leading to Study Withdrawal up to Week 52
时间窗: Up to Week 52
An AE is any untoward medical occurrence in a clinical study participant administered a medicinal product and which does not necessarily have a causal relationship with that product.
