PGIS-Fatigue measured participants' perception of their fatigue severity (7-day recall) on a 4-point scale ranging from '1=none' to '4=severe'. A participant was considered to have achieved the PGIS-Fatigue response at Weeks 12, 16, 20, or 24, if their baseline to postbaseline score met one of the following conditions: 'none' at baseline to 'none' postbaseline; 'mild' to 'mild' or 'none'; 'moderate' to 'mild' or 'none'; or 'severe' to 'moderate', 'mild', or 'none'.

The PGIC-Fatigue assesses change over time compared with baseline on a 5-point scale ranging from 0 to 4 where 0 indicates Much better and 4 as Much worse. A participant was considered to have achieved the PGIC-Fatigue response at Weeks 12, 16, 20, or 24 if their baseline PGIS and corresponding PGIC met one of the following conditions: if the PGIS at baseline was 'none' or 'mild' and PGIC at the visit was 'no change', 'a little better', or 'much better'; or if the PGIS at baseline was 'moderate' or 'severe' and PGIC at the visit was 'a little better' or 'much better'.

Double-Blind Period: Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Serious TEAEs, Related TEAEs and TEAEs With Severity Greater Than or Equal to Grade 3
Periodo de tiempo: Double-Blind Period: From the time of signing informed consent to Week 24

AE is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with the study drug. A serious adverse event (SAE) is any untoward medical occurrence that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. TEAEs are AEs with an initial onset date during the on-treatment period or worsening from baseline and includes both serious & non-serious TEAEs. Severity of AEs was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE; Version 4.03): grade 1: mild; grade 2: moderate; grade 3: severe or medically significant but not immediately life-threatening; grade 4: life threatening or disabling; grade 5: death related to AE.

TEAEs are AEs with an initial onset date during the on-treatment period or worsening from baseline and includes both serious & non-serious TEAEs. Severity of abnormalities was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE; Version 4.03): grade 1: mild; grade 2: moderate; grade 3: severe or medically significant but not immediately life-threatening; grade 4: life threatening or disabling; grade 5: death related to AE.
