MeasureTime frameDescription
Number of Participants With Treatment-Emergent Adverse Events (TEAEs)From the start of study drug to 28 days after last dose; Treatment Phase median duration of treatment was 358 and 320 days for Placebo and Pomalidomide; Extension phase median duration of treatment was 161 days and 194 days for Placebo and pomalidomide.An adverse event (AE) is any noxious, unintended, or untoward medical occurrence that may appear or worsen during the course of a study. A TEAE is any AE that began or worsened on or after the start of study drug through 28 days after the last dose. A treatment-related TEAE is a TEAE which was considered by the investigator to be related to study drug. The severity/intensity of AEs was assessed by the investigator as Mild (asymptomatic or mild symptoms; intervention not indicated), Moderate (symptoms cause moderate discomfort, intervention may be required), or Severe (symptoms cause severe discomfort/pain, requiring medical intervention, inability to perform daily activities). A serious AE is any AE that: - Resulted in death; - Was life-threatening; - Required inpatient hospitalization or prolongation of existing hospitalization - Resulted in persistent or significant disability/incapacity; - Was a congenital anomaly/birth defect; - Constituted an important medical event.
Change From Baseline in Percent Predicted Forced Vital Capacity (FVC) at Week 52Baseline (defined as the average of all values between Screening and Baseline) and Weeks 48 and 52Forced vital capacity (FVC) is a pulmonary function test and is the volume of air in the lungs that can forcibly be blown out after a full inhalation. Percent predicted values are based comparison between the participant's measured value with expected FVC for someone of the same sex, age and height (reference value). For the analysis of FVC, the baseline value was defined as the average of all values between Screening and Baseline (inclusive), and the average of Weeks 48 and 52 was treated as the Week 52 value, to reduce the total data variability at the key time points.
Change From Baseline in the Modified Rodnan Skin Score (mRSS) at Week 52/Early TerminationBaseline and Week 52 (or the Treatment Phase Early Termination visit)Improvement in skin thickening is associated with improved survival and may be useful as a surrogate measurement in clinical studies.

Change From Baseline in Percent Predicted Forced Vital Capacity (FVC) at Week 52

Forced vital capacity (FVC) is a pulmonary function test and is the volume of air in the lungs that can forcibly be blown out after a full inhalation. Percent predicted values are based comparison between the participant's measured value with expected FVC for someone of the same sex, age and height (reference value). For the analysis of FVC, the baseline value was defined as the average of all values between Screening and Baseline (inclusive), and the average of Weeks 48 and 52 was treated as the Week 52 value, to reduce the total data variability at the key time points.

Time frame: Baseline (defined as the average of all values between Screening and Baseline) and Weeks 48 and 52

Population: The Full Analysis Set (FAS) consisted of all randomized participants who received at least one dose of study drug. Participants with a Baseline value and a Week 52 were included in the analysis.

Change From Baseline in the Modified Rodnan Skin Score (mRSS) at Week 52/Early Termination

Improvement in skin thickening is associated with improved survival and may be useful as a surrogate measurement in clinical studies. The mRSS is an assessment tool which is used to evaluate the extent and severity of the skin thickening associated with systemic sclerosis (SSc). Seventeen body areas were evaluated on a 4-point scale (0 \[normal\], 1 \[mild\], 2 \[moderate\]), or 3 \[severe\]). The total score, which is the sum of the 17 individual body assessments, can range from 0 to 51.

Change From Baseline in University of California, Los Angeles, Scleroderma Clinical Trial Consortium Gastrointestinal Tract (UCLA SCTC GIT 2.0) Total Score at Week 52/Early Termination

The UCLA SCTC GIT 2.0 is a 34-item, health-related quality of life self-administered evaluation tool, which targets gastrointestinal (GI) activity and severity in patients with SSc. Individual scales include reflux, distention/bloating, fecal soilage, diarrhea, social functioning, emotional well-being and constipation. The items are scored on a scale from 0 to 3, where 0 indicates better health and 3 indicates worse health (except for Questions 15 and 31 which are scored as 0 (better health) or 1 (worse health). The total score is calculated as the average of the first 6 scale scores (excluding constipation) which captures overall burden (severity) of SSc-associated GIT. The overall score ranges from 0 to 3, where higher scores indicate more severe symptoms.

Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

An adverse event (AE) is any noxious, unintended, or untoward medical occurrence that may appear or worsen during the course of a study. A TEAE is any AE that began or worsened on or after the start of study drug through 28 days after the last dose. A treatment-related TEAE is a TEAE which was considered by the investigator to be related to study drug. The severity/intensity of AEs was assessed by the investigator as Mild (asymptomatic or mild symptoms; intervention not indicated), Moderate (symptoms cause moderate discomfort, intervention may be required), or Severe (symptoms cause severe discomfort/pain, requiring medical intervention, inability to perform daily activities). A serious AE is any AE that: - Resulted in death; - Was life-threatening; - Required inpatient hospitalization or prolongation of existing hospitalization - Resulted in persistent or significant disability/incapacity; - Was a congenital anomaly/birth defect; - Constituted an important medical event.

Time frame: From the start of study drug to 28 days after last dose; Treatment Phase median duration of treatment was 358 and 320 days for Placebo and Pomalidomide; Extension phase median duration of treatment was 161 days and 194 days for Placebo and pomalidomide.

Population: All randomized participants who received at least one dose of the study treatment (either pomalidomide or placebo).

Change From Baseline in Dyspnea Functional Impairment at Week 12

The Transition Dyspnea Index (TDI) provides interview-based measurements of breathlessness related to activities of daily living. The TDI is an evaluative instrument that includes specific criteria for each of three components (functional impairment, magnitude of task and magnitude of effort) to measure changes from a baseline state. Changes in dyspnea functional impairment were assessed on a scale from Major Deterioration (formerly working but had to stop working and abandoned usual activities due to shortness of breath) to Major Improvement (able to return to work at former pace and return to full activities with only mild restriction due to improvement of shortness of breath). Further impairment for other reasons includes participants who gave up or reduced work or other activities for reasons other than shortness of breath.

Change From Baseline in Dyspnea Magnitude of Effort at Week 24

The Transition Dyspnea Index (TDI) provides interview-based measurements of breathlessness related to activities of daily living. The TDI is an evaluative instrument that includes specific criteria for each of three components (functional impairment, magnitude of task and magnitude of effort) to measure changes from a baseline state. At Baseline magnitude of task was assessed on a scale from Grade 0 (becomes short of breath at rest, while sitting or lying) to Grade 4 (becomes short of breath only with greatest imaginable effort). Changes in dyspnea magnitude of task were assessed on a scale from Major Deterioration (severe decrease in effort from Baseline to avoid shortness of breath, activities take 50-100% longer to complete) to Major Improvement (able to do things with much greater effort than previously with few, if any, pauses). Further impairment for other reasons includes participants with reduced exertion capacity for reasons other than shortness of breath.

Change From Baseline in Modified Rodnan Skin Score Over Time

Improvement in skin thickening is associated with improved survival and may be useful as a surrogate measurement in clinical studies. The mRSS is an assessment tool which is used to evaluate the extent and severity of the skin thickening associated with systemic sclerosis (SSc). Seventeen body areas were evaluated on a 4-point scale (0 \[normal\], 1 \[mild\], 2 \[moderate\], or 3 \[severe\]). The total score, which is the sum of the 17 individual body assessments, can range from 0 to 51.

Time frame: Baseline and Weeks 12, 24, 64, 76, and 156 (or the Extension Phase Early Termination visit).

Change From Baseline in Percent Predicted Forced Vital Capacity Over Time

Forced vital capacity (FVC) is a pulmonary function test and is the volume of air in the lungs that can forcibly be blown out after a full inhalation. Percent predicted values are based comparison between the participant's measured value with expected FVC for someone of the same sex, age and height (reference value).

Change From Baseline in UCLA SCTC GIT 2.0 Constipation Subscale Score Over Time

The UCLA SCTC GIT 2.0 is a 34-item, health-related quality of life self-administered evaluation tool, which targets GI activity and severity in patients with SSc. Individual scales include reflux, distention/bloating, fecal soilage, diarrhea, social functioning, emotional well-being and constipation.
