MeasureTime frameDescription
Number of Participants Who Experienced Adverse Events (AEs) or Serious AEBaseline through 84 MonthsAn AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can be any unfavorable and unintended sign (i.e., abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Non-serious AEs are reported at a threshold of 5%. An SAE is an AE from this study that results in any of the following: death, initial or prolonged inpatient hospitalization, a life-threatening experience, persistent or significant disability/incapacity, congenital anomaly/birth defect, considered significant by the investigator for any other reason A summary of serious adverse events (SAEs) and other non-serious adverse events (AEs), regardless of causality, were reported in the Reported Adverse Events module.

Change From Baseline of Originating Study in Modified Total Sharp Score (mTSS)Baseline, Year 1X-rays of the hands/wrists and feet were scored for structural progression as measured using the mTSS. This methodology quantified the extent of bone erosions and joint space narrowing (JSN) for 44 and 42 joints, with higher scores representing greater damage. The mTSS at a time point is the sum of the erosion (range from 0 to 280) and JSN (range from 0 to 168) scores, for a maximum score of 448. Least Squares Mean (LSM) was calculated using a mixed model for repeated measures (MMRM) with treatment, visit, treatment-by-visit-interactions as fixed categorical effects and baseline and baseline-by-visit-interactions as fixed continuous effects.

Change From Baseline of Originating Study in European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Health State ScoresBaseline, Year 1The European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) is a standardized measure of health status of the participant. The first component is a descriptive system of the respondent's health comprised of the following 5 participant-reported dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The responses are used to derive the health state index scores using the United Kingdom (UK) algorithm, with scores ranging from -0.594 to 1, and the United States (US) algorithm, with scores ranging from -0.109 to 1. A higher score indicates better health state.
Change From Baseline of Originating Study in European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Scores (Self-Perceived Health)Baseline, Year 1The European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) is a standardized measure of health status of the participant. The second component is a self-perceived health score which is assessed using a VAS that ranged from 0 to 100 millimeter (mm), where 0 mm indicated the worst health you can imagine and 100 mm indicated the best health you can imagine.
Percentage of Participants Maintaining a Clinical Disease Activity Index Score (CDAI) ≤10Year 1 after entry into JADYThe CDAI is a tool for measurement of disease activity in RA that does not require a laboratory component and was scored by the investigative site. It integrates TJC28 (scored 0-28 with higher scores indicating higher disease activity), SJC28 (scored 0-28 with higher scores indicating higher disease activity), Patient's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity), and Physician's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity). The CDAI is calculated by summing the values of the 4 components. CDAI scores range from 0 to 76; lower scores indicated lower disease activity. A negative change from baseline indicates improvement in condition.
Percentage of Participants Maintaining a Clinical Disease Activity Index Score (CDAI) ≤ 2.8Year 1 after entry into JADYThe CDAI is a tool for measurement of disease activity in RA that does not require a laboratory component and was scored by the investigative site. It integrates TJC28 (scored 0-28 with higher scores indicating higher disease activity), SJC28 (scored 0-28 with higher scores indicating higher disease activity), Patient's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity), and Physician's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity). The CDAI is calculated by summing the values of the 4 components. CDAI scores range from 0 to 76; lower scores indicated lower disease activity. A negative change from baseline indicates improvement in condition.
Percentage of Participants Maintaining a Clinical Disease Activity Index Score (CDAI) ≤2.8Year 3 after entry into JADYThe CDAI is a tool for measurement of disease activity in RA that does not require a laboratory component and was scored by the investigative site. It integrates TJC28 (scored 0-28 with higher scores indicating higher disease activity), SJC28 (scored 0-28 with higher scores indicating higher disease activity), Patient's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity), and Physician's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity). The CDAI is calculated by summing the values of the 4 components. CDAI scores range from 0 to 76; lower scores indicated lower disease activity. A negative change from baseline indicates improvement in condition.
Percentage of Participants Maintaining a Health Assessment Questionnaire Disability Index (HAQ-DI) Improvement ≥0.22Year 1 after entry into JADYThe HAQ-DI questionnaire assesses the participant's self-perception on the degree of difficulty \[0 (without any difficulty), 1 (with some difficulty), 2 (with much difficulty), and 3 (unable to do)\] when dressing and grooming, arising, eating, walking, hygiene, reaching, gripping, and performing other daily activities. Scores for each functional area were averaged to calculate HAQ-DI scores, which ranged from 0 (no disability) to 3 (worst disability). A decrease in HAQ-DI score indicated an improvement in the participant's condition. An improvement of 0.22 or 0.3 points on the HAQ-DI has been identified as a minimal clinically important difference in Rheumatoid Arthritis participants.
Percentage of Participants Maintaining a Health Assessment Questionnaire Disability Index (HAQ-DI) Improvement ≥0.3Year 1 after entry into JADYThe HAQ-DI questionnaire assesses the participant's self-perception on the degree of difficulty \[0 (without any difficulty), 1 (with some difficulty), 2 (with much difficulty), and 3 (unable to do)\] when dressing and grooming, arising, eating, walking, hygiene, reaching, gripping, and performing other daily activities. Scores for each functional area were averaged to calculate HAQ-DI scores, which ranged from 0 (no disability) to 3 (worst disability). A decrease in HAQ-DI score indicated an improvement in the participant's condition. An improvement of 0.22 or 0.3 points on the HAQ-DI has been identified as a minimal clinically important difference in Rheumatoid Arthritis participants.
Change From Baseline of Originating Study in Bone Erosion ScoreBaseline, Year 1The joint erosion score is a summary of erosion severity in 32 joints of the hands and 12 joints of the feet. The maximum erosion score for a hand joint is 5 and for a foot joint is 10. Thus, the maximal erosion score is 280 for a timepoint (160 for both hands/ wrists and 120 for both feet). Each joint is scored according to the surface area involved from 0 to 5 for hand joints and 0 to 10 for the foot joints. The highest score (5 for the hand and 10 for the foot) indicates extensive loss of bone from more than one half of the articulating bone. A score of 0 in either the hand or foot joints indicates no erosion. LSM was calculated using an MMRM model with treatment, baseline value, visit, and the interactions of baseline-by-visit and treatment-by-visit as fixed factors.
Healthcare Resource UtilizationBaseline up to 84 MonthsNumber of visits to medical care providers related to treatment of Rheumatoid Arthritis (RA) outside of the clinical study. Reported here are healthcare consultations and emergency room consultations from end of originating study to end of participation in study JADY.
Percentage of Participants Maintaining a Simplified Disease Activity Index (SDAI) ≤11Year 1 after entry into JADYSDAI is a tool for measurement of disease activity in RA that integrates TJC28, SJC28, acute phase response using C-reactive protein (milligrams per liter), Patient's Global Assessment of Disease Activity using visual analog scale (cm), and Physician's Global Assessment of Disease Activity using visual analog scale (cm). The SDAI is calculated by summing the values of the 5 components. Lower scores indicated less disease activity. The SDAI is expressed as a score on a scale with the minimum score=0 (best) to maximum score=86 (worst). Low disease activity is defined as a SDAI score ≤11.
Percentage of Participants Maintaining a Simplified Disease Activity Index (SDAI) ≤3.3Year 1 after entry into JADYSDAI is a tool for measurement of disease activity in RA that integrates TJC28, SJC28, acute phase response using C-reactive protein (milligrams per liter), Patient's Global Assessment of Disease Activity using visual analog scale (cm), and Physician's Global Assessment of Disease Activity using visual analog scale (cm). The SDAI is calculated by summing the values of the 5 components. Lower scores indicated less disease activity. The SDAI is expressed as a score on a scale with the minimum score=0 (best) to maximum score=86 (worst). Disease remission is defined as an SDAI score of ≤3.3.
Percentage of Participants With Relapse Event During the 96-Week Step-Down PeriodWeek 0 through Week 96 of Step-downRelapse is defined as a Clinical Disease Activity Index score \> 10. The CDAI is a tool for measurement of disease activity in RA that does not require a laboratory component and was scored by the investigative site. It integrates TJC28 (scored 0-28 with higher scores indicating higher disease activity), SJC28 (scored 0-28 with higher scores indicating higher disease activity), Patient's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity), and Physician's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity). The CDAI is calculated by summing the values of the 4 components. CDAI scores range from 0 to 76; lower scores indicated lower disease activity. Total number of participants at risk multiplied by estimate of cumulative event probability would need to be rounded up or down to get a whole number.
Change From Baseline of Originating Study in Duration of Morning StiffnessBaseline, Year 1Participants reported the duration of their morning joint stiffness (MJS) in hours and minutes. The participants were asked about their duration of morning joint stiffness on the day prior to the study visit to capture actual symptoms, since the participant may have had an atypical morning routine on the day of the study visit. If morning joint stiffness duration was longer than 12 hours (720 minutes), it was truncated to 720 minutes for statistical presentations and analyses. A decrease in duration of morning joint stiffness indicated an improvement in the participant's condition.

Number of Participants Who Experienced Adverse Events (AEs) or Serious AE

An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can be any unfavorable and unintended sign (i.e., abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. Non-serious AEs are reported at a threshold of 5%. An SAE is an AE from this study that results in any of the following: death, initial or prolonged inpatient hospitalization, a life-threatening experience, persistent or significant disability/incapacity, congenital anomaly/birth defect, considered significant by the investigator for any other reason A summary of serious adverse events (SAEs) and other non-serious adverse events (AEs), regardless of causality, were reported in the Reported Adverse Events module.

Time frame: Baseline through 84 Months

Population: All enrolled participants who received at least one dose of study drug and did not discontinue the study for the reason 'Lost to Follow-up' at the first postbaseline visit in study JADY.

Change From Baseline of Originating Study in Bone Erosion Score

The joint erosion score is a summary of erosion severity in 32 joints of the hands and 12 joints of the feet. The maximum erosion score for a hand joint is 5 and for a foot joint is 10. Thus, the maximal erosion score is 280 for a timepoint (160 for both hands/ wrists and 120 for both feet). Each joint is scored according to the surface area involved from 0 to 5 for hand joints and 0 to 10 for the foot joints. The highest score (5 for the hand and 10 for the foot) indicates extensive loss of bone from more than one half of the articulating bone. A score of 0 in either the hand or foot joints indicates no erosion. LSM was calculated using an MMRM model with treatment, baseline value, visit, and the interactions of baseline-by-visit and treatment-by-visit as fixed factors.

Time frame: Baseline, Year 1

Population: All enrolled participants treated with at least one dose of study drug in JADY with available baseline (from originating study) and at least 1 postbaseline x-ray assessment (collected in JADY). Year 1 data not available, zero participants analyzed due to no data collected in this study or originating study.

Change From Baseline of Originating Study in Duration of Morning Stiffness

Participants reported the duration of their morning joint stiffness (MJS) in hours and minutes. The participants were asked about their duration of morning joint stiffness on the day prior to the study visit to capture actual symptoms, since the participant may have had an atypical morning routine on the day of the study visit. If morning joint stiffness duration was longer than 12 hours (720 minutes), it was truncated to 720 minutes for statistical presentations and analyses. A decrease in duration of morning joint stiffness indicated an improvement in the participant's condition.

Change From Baseline of Originating Study in European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Health State Scores

The European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) is a standardized measure of health status of the participant. The first component is a descriptive system of the respondent's health comprised of the following 5 participant-reported dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each dimension has 5 levels: no problems, slight problems, moderate problems, severe problems, and extreme problems. The responses are used to derive the health state index scores using the United Kingdom (UK) algorithm, with scores ranging from -0.594 to 1, and the United States (US) algorithm, with scores ranging from -0.109 to 1. A higher score indicates better health state.

Change From Baseline of Originating Study in Joint Space Narrowing at Year 1

X-rays of the hands/wrists and feet were assessed for joint space narrowing (JSN) and bone erosions. Assessment of JSN for each hand (15 joints per hand) and foot (6 joints per foot), including subluxation, is scored from 0 to 4, with 0 indicating no (normal) JSN and 4 indicating complete loss of joint space, bony ankylosis or luxation. JSN scores ranged from 0-168. A score of 0 would indicate no change and higher scores represent a worsening of joint space narrowing.

Time frame: Baseline, Year 1

Population: All enrolled participants treated with at least one dose of study drug in JADY with available baseline (from originating study) and at least 1 postbaseline x-ray assessment (collected in JADY).

Change From Baseline of Originating Study in Modified Total Sharp Score (mTSS)

X-rays of the hands/wrists and feet were scored for structural progression as measured using the mTSS. This methodology quantified the extent of bone erosions and joint space narrowing (JSN) for 44 and 42 joints, with higher scores representing greater damage. The mTSS at a time point is the sum of the erosion (range from 0 to 280) and JSN (range from 0 to 168) scores, for a maximum score of 448. Least Squares Mean (LSM) was calculated using a mixed model for repeated measures (MMRM) with treatment, visit, treatment-by-visit-interactions as fixed categorical effects and baseline and baseline-by-visit-interactions as fixed continuous effects.

Percentage of Participants Maintaining a Clinical Disease Activity Index Score (CDAI) ≤10

The CDAI is a tool for measurement of disease activity in RA that does not require a laboratory component and was scored by the investigative site. It integrates TJC28 (scored 0-28 with higher scores indicating higher disease activity), SJC28 (scored 0-28 with higher scores indicating higher disease activity), Patient's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity), and Physician's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity). The CDAI is calculated by summing the values of the 4 components. CDAI scores range from 0 to 76; lower scores indicated lower disease activity. A negative change from baseline indicates improvement in condition.

DAS28 consisted of composite score of following variables: tender joint count (TJC28), swollen joint count (SJC28), ESR (millimeters per hour), and Patient's Global Assessment of Disease Activity. DAS28 was calculated using following formula: DAS28-ESR=0.56\*square root (sqrt)(TJC28)+0.28\*sqrt(SJC28)+0.70\*natural log(ESR)+0.014\*Patient's Global VAS. Total scores ranged from 1.0-9.4, where lower scores indicated less disease activity.

The HAQ-DI questionnaire assesses the participant's self-perception on the degree of difficulty \[0 (without any difficulty), 1 (with some difficulty), 2 (with much difficulty), and 3 (unable to do)\] when dressing and grooming, arising, eating, walking, hygiene, reaching, gripping, and performing other daily activities. Scores for each functional area were averaged to calculate HAQ-DI scores, which ranged from 0 (no disability) to 3 (worst disability). A decrease in HAQ-DI score indicated an improvement in the participant's condition. An improvement of 0.22 or 0.3 points on the HAQ-DI has been identified as a minimal clinically important difference in Rheumatoid Arthritis participants.

Percentage of Participants Maintaining a Health Assessment Questionnaire Disability Index (HAQ-DI) Improvement ≥0.3

The HAQ-DI questionnaire assesses the participant's self-perception on the degree of difficulty \[0 (without any difficulty), 1 (with some difficulty), 2 (with much difficulty), and 3 (unable to do)\] when dressing and grooming, arising, eating, walking, hygiene, reaching, gripping, and performing other daily activities. Scores for each functional area were averaged to calculate HAQ-DI scores, which ranged from 0 (no disability) to 3 (worst disability). A decrease in HAQ-DI score indicated an improvement in the participant's condition. An improvement of 0.22 or 0.3 points on the HAQ-DI has been identified as a minimal clinically important difference in Rheumatoid Arthritis participants.

Percentage of Participants Maintaining a Simplified Disease Activity Index (SDAI) ≤11

SDAI is a tool for measurement of disease activity in RA that integrates TJC28, SJC28, acute phase response using C-reactive protein (milligrams per liter), Patient's Global Assessment of Disease Activity using visual analog scale (cm), and Physician's Global Assessment of Disease Activity using visual analog scale (cm). The SDAI is calculated by summing the values of the 5 components. Lower scores indicated less disease activity. The SDAI is expressed as a score on a scale with the minimum score=0 (best) to maximum score=86 (worst). Low disease activity is defined as a SDAI score ≤11.

Percentage of Participants Maintaining a Simplified Disease Activity Index (SDAI) ≤3.3

SDAI is a tool for measurement of disease activity in RA that integrates TJC28, SJC28, acute phase response using C-reactive protein (milligrams per liter), Patient's Global Assessment of Disease Activity using visual analog scale (cm), and Physician's Global Assessment of Disease Activity using visual analog scale (cm). The SDAI is calculated by summing the values of the 5 components. Lower scores indicated less disease activity. The SDAI is expressed as a score on a scale with the minimum score=0 (best) to maximum score=86 (worst). Disease remission is defined as an SDAI score of ≤3.3.

Percentage of Participants With mTSS Change ≤0

X-rays of the hands/wrists and feet were scored for structural progression as measured using the mTSS. This methodology quantified the extent of bone erosions and joint space narrowing (JSN) for 44 and 42 joints, with higher scores representing greater damage. The mTSS at a time point is the sum of the erosion (range from 0 to 280) and JSN (range from 0 to 168) scores, for a maximum score of 448, with higher scores representing greater damage.

Percentage of Participants With Relapse Event During the 96-Week Step-Down Period

Relapse is defined as a Clinical Disease Activity Index score \> 10. The CDAI is a tool for measurement of disease activity in RA that does not require a laboratory component and was scored by the investigative site. It integrates TJC28 (scored 0-28 with higher scores indicating higher disease activity), SJC28 (scored 0-28 with higher scores indicating higher disease activity), Patient's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity), and Physician's Global Assessment of Disease Activity (scored on a visual analogue scale from 0-10 cm with higher scores indicating higher disease activity). The CDAI is calculated by summing the values of the 4 components. CDAI scores range from 0 to 76; lower scores indicated lower disease activity. Total number of participants at risk multiplied by estimate of cumulative event probability would need to be rounded up or down to get a whole number.
