Participant Flow

All participants were recruited in the United States

Treatment periods for Cohorts 1 and 2 did not have the same participants. Participants in each cohort were randomized to sequence. In each sequence the first treatment was given for 14 days, there was a 7-day washout period, and then the second treatment was given for 14 days.

Population: Safety Population.

An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An SAE is any untoward medical occurrence that results in death;is life-threatening;requires inpatient hospitalization or prolongation of present hospitalization;results in persistent or significant disability/incapacity;is a congenital anomaly/birth defect;or is a medically important event that may not be immediately life-threatening or result in death or hospitalization, but may jeopardize the participant or may require intervention to prevent one of other outcomes listed in definition above, or involves suspected transmission via a medicinal product of an infectious agent.
