Registered outcomes16

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryNumber of Participants With Treatment-related Adverse Events as Assessed by Protocol Definition of AE14 days of losartan treatment
Safety will be reported based on Protocol defined AEs. For the purpose of this protocol, an AE will be defined as as any untoward medical occurrence in a subject during the study listed under DMSB - Anticipated Adverse Events and Grading Scale section of this protocol as well as safety monitoring data listed on protocol table 1 as well as stoppage criteria for losartan. The event does not necessarily have a causal relationship with the treatment. AEs will be collected for both study groups, treatment and control from the time the ICF is signed until the subject completes study participation.
