What researchers measure

Primary outcomes

  1. Number of Participants With Adverse Events and Adverse Reactions

    An adverse event is any unfavorable medical event occurring in a subject to whom an investigational product is administered, and a causal relationship between the administered investigational product and an adverse event is not always clarified. That is, an adverse event is any unfavorable or unintended sign (including an abnormal change in laboratory test values), symptom, or disease, and a causal relationship to the relevant investigational product is not considered. Any adverse event that was treatment-related was considered an adverse reaction.

    Time frame: Throughout 1 year of study
