What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With an American College of Rheumatology 20% Improvement (ACR 20) Response at Week 16

    Percentage of participants with an American College of Rheumatology 20% Improvement (ACR 20) response. A participant was a responder if the following 3 criteria for improvement from Baseline were met:

    • ≥ 20% improvement in 68 tender joint count;
    • ≥ 20% improvement in 66 swollen joint count; and
    • ≥ 20% improvement in at least 3 of the 5 following parameters: Subject's assessment of pain (measured on a 100 mm visual analog scale [VAS]); Subject's global assessment of disease activity (measured on a 100 mm VAS); Physician's global assessment of disease activity (measured on a 100 mm VAS); Subject's self-assessment of physical function (Health Assessment Questionnaire - Disability Index ([HAQ-DI]); C-Reactive Protein.

    Measured: Baseline and Week 16

Secondary outcomes (72)
  1. Change From Baseline in Health Assessment Questionnaire-Disability Index (HAQ-DI) at Week 16

    The Health Assessment Questionnaire - Disability Index (HAQ-DI) was a patient-reported questionnaire consisting of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and usual activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from Baseline in the overall score indicate improvement in functional ability.

    Measured: Baseline and Week 16

  2. Percentage of Participants With an American College of Rheumatology 20% Improvement (ACR 20) Response at Week 24

    Percentage of participants with an American College of Rheumatology 20% Improvement (ACR 20) response. A participant was a responder if the following 3 criteria for improvement from baseline were met:

    • ≥ 20% improvement in 68 tender joint count;
    • ≥ 20% improvement in 66 swollen joint count; and
    • ≥ 20% improvement in at least 3 of the 5 following parameters: Subject's assessment of pain (measured on a 100 mm visual analog scale [VAS]); Subject's global assessment of disease activity (measured on a 100 mm VAS); Physician's global assessment of disease activity (measured on a 100 mm VAS); Subject's self-assessment of physical function (Health Assessment Questionnaire - Disability Index ([HAQ-DI]); C-Reactive Protein

    Measured: Baseline and Week 24

  3. Change From Baseline in Health Assessment Questionnaire - Disability Index (HAQ-DI) at Week 24

    The Health Assessment Questionnaire - Disability Index (HAQ-DI) is a patient-reported questionnaire consisting of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and usual activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from Baseline in the overall score indicate improvement in functional ability.

    Measured: Baseline and Week 24

  4. Change From Baseline in the Medical Outcome Study Short Form 36-item (SF-36) Physical Functioning Domain at Week 16

    The Medical Outcome Study Short Form 36-Item Health Survey, Version 2 (SF-36) is a self-administered instrument that measures the impact of disease on overall quality of life and consists of 36 questions in eight domains (physical function, pain, general and mental health, vitality, social function, physical and emotional health). The concepts measured by the SF-36 are not specific to any age, disease, or treatment group, allowing comparison of relative burden of different diseases and the relative benefit of different treatments. Norm-based scores were used in analyses, calibrated so that 50 is the average score and the standard deviation equals 10. Higher scores indicate a higher level of functioning. The physical functioning domain assesses limitations in physical activities because of health problems. A positive change from baseline score indicates an improvement.

    Measured: Baseline and Week 16

  5. Change From Baseline in the Clinical Disease Activity Index (CDAI) at Week 16

    The Clinical Disease Activity Index (CDAI) is a composite index that is calculated as the sum of the:

    • 28 tender joint count (TJC),
    • 28 swollen joint count (SJC),
    • Subject's Global Assessment of Disease Activity measured on a 100 mm visual analog scale (VAS), where 0 mm = lowest disease activity and 100 mm = highest;
    • Physician's Global Assessment of Disease Activity -measured on a 100 mm VAS, where 0 mm = lowest disease activity and 100 mm = highest.

    The CDAI score ranges from 0-76 where lower scores indicate less disease activity. The following thresholds of disease activity have been defined for the CDAI:

    Remission: ≤ 2.8; Low Disease Activity: > 2.8 and ≤ 10; Moderate Disease Activity: > 10 and ≤ 22; High Disease Activity: > 22

    Measured: Baseline and Week 16

  6. Percentage of Participants Who Achieve Low Disease Activity or Remission Based on the Clinical Disease Activity Index (CDAI) ≤ 10 at Week 16

    The Clinical Disease Activity Index (CDAI) is a composite index that is calculated as the sum of the:

    • 28 tender joint count (TJC),
    • 28 swollen joint count (SJC),
    • Subject's Global Assessment of Disease Activity measured on a 100 mm visual analog scale (VAS), where 0 mm = lowest disease activity and 100 mm = highest;
    • Physician's Global Assessment of Disease Activity -measured on a 100 mm VAS, where 0 mm = lowest disease activity and 100 mm = highest.

    The CDAI score ranges from 0-76 where lower scores indicate less disease activity. The following thresholds of disease activity have been defined for the CDAI:

    Remission: ≤ 2.8; Low Disease Activity: > 2.8 and ≤ 10; Moderate Disease Activity: > 10 and ≤ 22; High Disease Activity: > 22

    Measured: Baseline and Week 16

  7. Change From Baseline in Disease Activity Score 28 (DAS28) (Using C-Reactive Protein) (CRP) at Week 16

    The DAS28 measures the severity of disease at a specific time and is derived from the following variables:

    • 28 tender joint count (TJC28)
    • 28 swollen joint count (SJC28), which do not include the distal interphalangeal (DIP) joints, the hip joint, or the joints below the knee;
    • C-reactive protein (CRP)
    • Subject's global assessment of disease activity (SGA )

    DAS28 values range from 2.0 to 10.0 while higher values mean a higher disease activity.

    A DAS28 score higher than 5.1 indicates high disease activity, a DAS28 score less than 3.2 indicates low disease activity, and a DAS28 score less than 2.6 indicates clinical remission.

    Measured: Baseline and Week 16

  8. Percentage Change From Baseline in the Tender Joint Count at Week 16

    Joint tenderness is the presence of pain in a joint when pressure is applied by the examiner to elicit tenderness. The 68 tender joint count evaluates the following joints: upper-temporomandibular, sternoclavicular, acromioclavicular, shoulder, elbow, wrist, meta-carpophalangeal, proximal interphalangeal and distal interphalangeal; lower: hip, knee, ankle, midtarsal, metatarsophalangeal and proximal interphalangeal.

    Measured: Baseline and Week 16

  9. Percentage Change From Baseline in the Swollen Joint Count at Week 16

    Joint swelling is soft tissue swelling that is detectable along the joint margins and is assessed by inspection and direct palpation of the joint, by the examiner. The ACR 66 swollen joint count evaluates the following joints: upper-temporomandibular, sternoclavicular, acromioclavicular, shoulder, elbow, wrist, metacarpophalangeal, proximal interphalangeal and distal interphalangeal; lower: knee, ankle, midtarsal, metatarsophalangeal and proximal interphalangeal.

    Measured: Baseline and Week 16

  10. Percentage Change From Baseline in the Subject Assessment of Pain at Week 16

    The Subject Assessment of Pain was measured asking the participant to place a vertical line on a 100-mm visual analog scale on which the left-hand boundary (score = 0 mm) represents "no pain," and the right-hand boundary (score = 100 mm) represents "pain as severe as can be imagined." The distance from the mark to the left-hand boundary was recorded in millimeters.

    Measured: Baseline and Week 16

  11. Percentage Change From Baseline in the Subject Global Assessment of Disease Activity at Week 16

    The Subject Global Assessment of Disease Activity was measured asking the participant to place a vertical line on a 100-mm visual analog scale on which the left-hand boundary (score = 0 mm) represents " lowest disease activity," and the right-hand boundary (score = 100 mm) represents " highest disease activity." The distance from the mark to the left-hand boundary was recorded in millimeters.

    Measured: Baseline and Week 16

  12. Percentage Change From Baseline in the Physician Global Assessment of Disease Activity at Week 16

    The Physician Global Assessment of Disease Activity was measured asking the physician to assess the subject's current arthritis disease activity by placing a vertical line on a 100-mm visual analog scale on which the left-hand boundary (score = 0 mm) represents " lowest disease activity," and the right-hand boundary (score = 100 mm) represents " highest disease activity." The distance from the mark to the left-hand boundary was recorded in millimeters.

    Measured: Baseline and Week 16

  13. Percentage Change From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) Score at Week 16

    The Health Assessment Questionnaire - Disability Index (HAQ-DI) was a patient-reported questionnaire consisting of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and usual activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from Baseline in the overall score indicate improvement in functional ability.

    Measured: Baseline and Week 16

  14. Percentage Change From Baseline in the High Sensitivity C-Reactive Protein (CRP) at Week 16

    C-Reactive Protein (CRP) is a substance produced by the liver that increases in the presence of inflammation in the body. An elevated CRP level is identified with blood tests and is considered a non-specific "marker" for disease.

    Measured: Baseline and Week 16

  15. Percentage Change From Baseline in Erythrocyte Sedimentation Rate (ESR) at Week 16

    The erythrocyte sedimentation rate (ESR) is a blood test that can reveal inflammatory activity. The subject's blood is placed in a tall, thin tube, red erythrocytes gradually settle to the bottom. Inflammation can cause the cells to clump together. Because these clumps of cells are denser than individual cells, they settle to the bottom more quickly.

    The ESR test measures the distance red blood cells fall in a test tube in one hour. The farther the red blood cells have descended, the greater the inflammatory response.

    Measured: Baseline and Week 16

  16. Change From Baseline in the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) Score at Week 16

    The FACIT-Fatigue scale was a 13-item self-administered questionnaire that assesses both the physical and functional consequences of fatigue. Each question is answered on a 5-point scale, where 0 means "not at all," and 4 means "very much." The FACIT-Fatigue scale score ranges from 0 to 52, with higher scores denoting lower levels of fatigue.

    A positive change from baseline score indicates an improvement.

    Measured: Baseline and Week 16

  17. Percentage of Participants Who Achieve an Improvement of ≥ 0.22 Units From Baseline in the Health Assessment Questionnaire-Disability Index (HAQ-DI) at Week 16

    The Health Assessment Questionnaire - Disability Index (HAQ-DI) was a patient-reported questionnaire consisting of 20 questions referring to eight domains: dressing/grooming, arising, eating, walking, hygiene, reach, grip, and usual activities. Participants assessed their ability to do each task over the past week using the following response categories: without any difficulty (0); with some difficulty (1); with much difficulty (2); and unable to do (3). Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from Baseline in the overall score indicate improvement in functional ability.

    Measured: Baseline and Week 16

  18. Percentage of Participants Who Achieve an Improvement of at Least 4 Units From Baseline in the Functional Assessment of Chronic Illness Therapy -Fatigue (FACIT-Fatigue) at Week 16

    The FACIT-Fatigue scale was a 13-item self-administered questionnaire that assesses both the physical and functional consequences of fatigue. Each question is answered on a 5-point scale, where 0 means "not at all," and 4 means "very much." The FACIT-Fatigue scale score ranges from 0 to 52, with higher scores denoting lower levels of fatigue.

    A positive change from baseline score indicates an improvement.

    Measured: Baseline and Week 16

  19. Percentage of Participants Who Achieve the European League Against Rheumatism (EULAR) Response Criteria Using CRP at Week 16

Scores on each task are summed and averaged to provide an overall score ranging from 0 to 3, where zero represents no disability and three very severe, high-dependency disability. Negative mean changes from Baseline in the overall score indicate improvement in functional ability.

    The study was terminated before the 2-year time point was reached due to lack of clinical efficacy.

    Measured: Baseline and Year 2

  62. Change From Baseline in the Medical Outcome Study Short Form 36-item (SF-36) Physical Functioning Domain at Year 2

    The Medical Outcome Study Short Form 36-Item Health Survey, Version 2 (SF-36) was a self-administered instrument that measures the impact of disease on overall quality of life and consists of 36 questions in eight domains (physical function, pain, general and mental health, vitality, social function, physical and emotional health). The concepts measured by the SF-36 are not specific to any age, disease, or treatment group, allowing comparison of relative burden of different diseases and the relative benefit of different treatments. Norm-based scores were used in analyses, calibrated so that 50 is the average score and the standard deviation equals 10. Higher scores indicate a higher level of functioning. The physical functioning domain assesses limitations in physical activities because of health problems. A positive change from baseline score indicates an improvement.

    The study was terminated before the 2-year time point was reached due to lack of clinical efficacy.

    Measured: Baseline and Year 2

  63. Change From Baseline in the Clinical Disease Activity Index (CDAI) at Year 2

    The Clinical Disease Activity Index (CDAI) is a composite index that is calculated as the sum of the:

    • 28 tender joint count (TJC),
    • 28 swollen joint count (SJC),
    • Subject's Global Assessment of Disease Activity measured on a 10 mm visual analog scale (VAS), where 0 mm = lowest disease activity and 10 mm = highest;
    • Physician's Global Assessment of Disease Activity -measured on a 10 mm VAS, where 0 mm = lowest disease activity and 10 mm = highest.

    The CDAI score ranges from 0-76 where lower scores indicate less disease activity. The following thresholds of disease activity have been defined for the CDAI:

    Remission: ≤ 2.8 Low Disease Activity: > 2.8 and ≤ 10 Moderate Disease Activity: > 10 and ≤ 22 High Disease Activity: > 22

    The study was terminated before the 2-year time point was reached due to lack of clinical efficacy.

    Measured: Baseline and Year 2

  64. Percentage of Participants Who Achieve Low Disease Activity or Remission Based on the Clinical Disease Activity Index (CDAI) ≤ 10 at Year 2

    The Clinical Disease Activity Index (CDAI) is a composite index that is calculated as the sum of the:

    • 28 tender joint count (TJC),
    • 28 swollen joint count (SJC),
    • Subject's Global Assessment of Disease Activity measured on a 10 mm visual analog scale (VAS), where 0 mm = lowest disease activity and 10 mm = highest;
    • Physician's Global Assessment of Disease Activity -measured on a 10 mm VAS, where 0 mm = lowest disease activity and 10 mm = highest.

    The CDAI score ranges from 0-76 where lower scores indicate less disease activity. The following thresholds of disease activity have been defined for the CDAI:

    Remission: ≤ 2.8 Low Disease Activity: > 2.8 and ≤ 10 Moderate Disease Activity: > 10 and ≤ 22 High Disease Activity: > 22

    The study was terminated before the 2-year time point was reached due to lack of clinical efficacy.

    Measured: Baseline and Year 2

  65. Change From Baseline in Disease Activity Score 28 (DAS28) (Using C-Reactive Protein) (CRP) at Year 2

    The DAS 28 measures the severity of disease at a specific time and is derived from the following variables:

    • 28 tender joint count (TJC28)
    • 28 swollen joint count (SJC28), which do not include the distal interphalangeal (DIP) joints, the hip joint, or the joints below the knee;
    • C-reactive protein (CRP)
    • Subject's global assessment of disease activity (SGA ). A DAS28 score higher than 5.1 indicates high disease activity, a DAS28 score less than 3.2 indicates low disease activity, and a DAS28 score less than 2.6 indicates clinical remission.

    DAS28 values range from 2.0 to 10.0 while higher values mean a higher disease activity.

    The study was terminated before the 2-year time point was reached due to lack of clinical efficacy.

    Measured: Baseline and Year 2

  66. Percentage Change From Baseline in the Individual American College of Rheumatology Components at Year 2

    The Individual ACR Components were defined as follows:

    1. Tender Joint Count (out of 68 joints)
    2. Swollen Joint Count (out of 66 joints)
    3. Subject Assessment of Pain (0 to 100 mm VAS)
    4. Subject Global Assessment of Disease Activity (0 to 100 mm VAS)
    5. Physician Global Assessment of Disease Activity (0 to 100 mm VAS)
    6. HAQ-DI Score
    7. Acute Phase Reactant High Sensitivity C-Reactive Protein (hsCRP, mg/dL) Erythrocyte Sedimentation Rate (ESR)

    The study was terminated before the 2-year time point was reached due to lack of clinical efficacy.

    Measured: Baseline and Year 2

  67. Change From Baseline in the Functional Assessment of Chronic Illness Therapy -Fatigue (FACIT-Fatigue) at Year 2

    The FACIT-Fatigue scale is a 13-item self-administered questionnaire that assesses both the physical and functional consequences of fatigue. Each question is answered on a 5-point scale, where 0 means "not at all," and 4 means "very much." The FACIT-Fatigue scale score ranges from 0 to 52, with higher scores denoting lower levels of fatigue.

    A positive change from baseline score indicates an improvement.

    The study was terminated before the 2-year time point was reached due to lack of clinical efficacy.

    Measured: Baseline and Year 2

  72. Percentage of Participants Who Achieve the European League Against Rheumatism (EULAR) Response Criteria Using CRP at Year 2

    EULAR response criteria classify each participant as a good, moderate or non-responder to treatment based on the degree of improvement from baseline and the level of disease activity at the endpoint. EULAR response is derived using the individual subject's DAS28 as the measure of severity of disease.

    Good or moderate response is defined as follows: Good response: DAS28 at the time point ≤ 3.2 and improvement from baseline > 1.2 Moderate response: DAS28 at the time point > 3.2 and improvement from baseline > 1.2, or DAS28 at the time point ≤ 5.1 and improvement from baseline > 0.6 and ≤ 1.2

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 27 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 8 May 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 50 sites in United States, Poland, Czechia, Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 15 Aug 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With an American College of Rheumatology 20% Improvement (ACR 20) Response at Week 16 (time frame: Baseline and Week 16). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01285310, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
