Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time To Intervention	Kaplan-Meier estimates are presented for time to treatment intervention. The estimates represent the quartiles of the survival time, where 50% corresponds to the median time to need for treatment intervention.; Need for intervention is defined as meeting ANY of the following criteria during the Double-Blind Treatment Period: OHSA Item #1 =2 unit worsening from Randomization (Visit 6) AND lack of efficacy as judged by the investigator; OR; OHSA Item #1 =2 unit worsening from Randomization (Visit 6) at 2 consecutive visits; OR; OHSA Item #1 =2 unit worsening from Randomization (Visit 6) at the visit before early discontinuation; OR; participant stops IMP or withdraws from study for patient-reported lack of efficacy.	Randomization (Day 0) up to Week 12
Secondary	Number of Participants Who Needed Intervention During the 12-week Double-Blind Treatment Period	Need for intervention is defined as meeting ANY of the following criteria during the Double-Blind Treatment Period: OHSA Item #1 =2 unit worsening from Randomization (Visit 6) AND lack of efficacy as judged by the investigator; OR; OHSA Item #1 =2 unit worsening from Randomization (Visit 6) at 2 consecutive visits; OR; OHSA Item #1 =2 unit worsening from Randomization (Visit 6) at the visit before early discontinuation; OR; participant stops IMP or withdraws from study for patient-reported lack of efficacy.	Randomization (Day 0) up to Week 12
Secondary	Time To All-cause Discontinuation	Kaplan-Meier estimates are presented for time to all-cause discontinuation. The estimates represent the quartiles of the survival time, where 50% corresponds to the median time to discontinuation. Time to all-cause discontinuation was defined as the time from randomization to withdrawal or last contact date.	Randomization (Day 0) up to Week 12
Secondary	Change From Randomization To All Post-randomization Visits in Orthostatic Hypotension Symptom Assessment (OHSA) Item #1 Score	The OHSA scale was designed to rate symptoms occurring specifically as a result of low blood pressure (BP), on average, over the past week using an 11-point scale (0 to 10), with more severe symptoms scoring higher. A score of zero indicates that the symptom was not experienced, and 10 is the worst possible. The scale was used to assess six symptoms: 1) Dizziness, lightheadedness, feeling faint, or feeling like you might black out, 2) problems with vision, 3) weakness, 4) fatigue, 5) trouble concentrating, and 6) head/neck discomfort. Scores for each activity and a composite score for all six activities were tabulated. A mean negative change from baseline means that symptoms have improved. A mean positive change from baseline means that symptoms have gotten worse.	Randomization (Day 0); Weeks 2 to 12
Secondary	Change From Randomization To All Post-randomization Visits in Orthostatic Hypotension Questionnaire (OHQ) Composite Score	The OHQ composite score was a mean of the OHSA composite and the Orthostatic Hypotension Daily Activity Scale (OHDAS) composite scores. The OHDAS was designed as a measure of quality of life. It uses an 11-point scale to assess whether orthostatic hypotension (OH) "interfered" with four types of activities: 1) standing for a short time, 2) standing for a long time, 3) walking for a short time, and 4) walking for a long time. A zero rating means that over the preceding week the activity was performed with no interference and a 10 rating means that orthostatic hypotension completely interfered with the activity. Scores for each activity and a composite score for all four activities were tabulated. A mean negative change from baseline means that symptoms have improved. A mean positive change from baseline means that symptoms have gotten worse.	Randomization (Day 0); Weeks 2 to 12
Secondary	Clinician-rated Clinical Global Impressions - Severity (CGI-S)	The CGI-S was developed to provide global measures of the severity of a participant's clinical condition during clinical studies. The CGI-S was utilized by both the clinician and the participant to provide an impression of the participant's current state of OH. The severity of the participant's current illness was rated by the clinician on a 7-point scale ranging from 1 (normal, no OH) to 7 (among those patients most extremely ill with OH).	Weeks 2 to 12
Secondary	Participant-rated CGI-S	The CGI-S was developed to provide global measures of the severity of a participant's clinical condition during clinical studies. The CGI-S was utilized by both the clinician and the participant to provide an impression of the participant's current state of OH. The severity of the participant's current illness was rated by the participant on a 7-point scale ranging from 1 (normal, no OH) to 7 (most extremely ill with OH).	Weeks 2 to 12
