For this analysis, baseline was defined as initial ACT13739 study baseline.

  23. Gastrointestinal Symptoms: Number of Participants With Stool Consistency Assessment by Bristol Stool Scale Scoring at Baseline and Weeks 26, 52, 104, and 156 [ Time Frame: Baseline of ACT13739 study and Weeks 26, 52, 104, and 156 post-ACT13739 baseline ]
    Participants were asked to rate their stool consistency in past 10 days (before each of the specified time points) on a 7-point Bristol stool scale, according to the following types: 1 = separate hard lumps, 2 = sausage shaped but lumpy, 3 = sausage-like with cracks on the surface, 4 = sausage-like but smooth and soft, 5 = soft blobs with clear cut edges, 6 = fluffy pieces with ragged edges, and 7 = watery with no solid pieces. Types 1 and 2 indicate constipation, types 3 and 4 indicate "ideal stools" (easiest to defecate), and 5-7 tending towards diarrhea. Frequency of each stool type was categorized as 'never', occasionally', or 'often'. For this analysis, baseline was defined as the initial ACT13739 study baseline.

  24. Change From Baseline in Beck Depression Inventory (BDI) Total Score at Weeks 26, 104, and 156 [ Time Frame: Baseline of ACT13739 study and Weeks 26, 104, and 156 post-ACT13739 baseline ]
    The BDI-II Scale was a 21-item scoring tool which measures the existence and severity of symptoms of depression. Each of the 21 items on BDI-II tool represent a depressive symptom. Each symptoms were scored on a 4-point scale of 0 to 3 (0=symptom not present); (3=symptom very intense). Scores for each symptom were added up to obtain the total scores for all 21 items, which were interpreted as follows: Scores of 0-13: minimal depression; 14-19: mild depression; 20-28: moderate depression and 29-63: severe depression, where higher scores indicated more depression. For this analysis, baseline was defined as initial ACT13739 study baseline.

  25. Change From Baseline in Albumin/Creatinine Ratio (ACR) and Protein/Creatinine Ratio (PCR) at Weeks 26, 52, 104, and 156 [ Time Frame: Baseline of ACT13739 study and Weeks 26, 52, 104, and 156 post-ACT13739 baseline ]
    For each scheduled visit for this assessment, 3 timed overnight urine samples were collected between 4 to 7 days of each other. All urine samples were collected within a 16-day period. ACR and PCR were determined for each collection. The median of the values determined for the 3 collections/visit was used for analysis. Baseline was defined as initial ACT13739 study baseline.

  26. Number of Participants in Categories of Echocardiogram (ECHO) Results at Baseline and at Weeks 26, 52, 104, and 156 [ Time Frame: Baseline of ACT13739 study and Weeks 26, 52, 104, and 156 post-ACT13739 baseline ]
    The summary statistics of all continuous echocardiogram variables were calculated for each visit. The overall interpretation of the readings were summarized in 3 categories: normal, abnormal but not clinically significant (NCS), and abnormal but clinically significant (CS) categories. For this analysis, baseline was defined as initial ACT13739 study baseline.

  27. Number of Participants in Categories of Brain Magnetic Resonance Imaging (MRI) Results at Baseline and Weeks 26, and 156 [ Time Frame: Baseline of ACT13739 study and Weeks 26, and 156 post-ACT13739 baseline ]
    All continuous MRI variables were summarized using descriptive statistics for each visit. The overall interpretation of the readings were summarized in 2 categories as: normal, and abnormal. For this analysis, baseline was defined as initial ACT13739 study baseline.

  28. Change From Baseline in Estimated Glomerular Filtration Rate (eGFR) at Weeks 26, 52, 104, and 156 [ Time Frame: Baseline of ACT13739 study and Weeks 26, 52, 104, and 156 post-ACT13739 baseline ]
    Estimated glomerular filtration rate was used to measure level of kidney function and determine the stage of kidney disease. Change from baseline in eGFR was obtained by subtracting baseline value from post-baseline value at Weeks 26, 52, 104 and 156. For this analysis, baseline was defined as initial ACT13739 study baseline.
