About this study

This is a Phase 3b, multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of apremilast monotherapy in subjects with active psoriatic arthritis.

Approximately 214 subjects will be randomized in a 1:1 ratio to either apremilast 30 mg BID (twice a day) or identically-appearing placebo, with approximately 107 subjects per treatment group.

This is a 113-week study. The subjects will spend 24 weeks in the double-blind, placebo-controlled treatment phase, followed by 28 weeks of active treatment phase (ie, up to Week 52 visit). The original treatment assignments (apremilast 30 mg BID (twice a day) or placebo) will remain blinded until all subjects have completed their Week 52 visit (or have discontinued). After the Week 52 visit, all subjects in the extension phase will continue to receive treatment with apremilast 30 mg BID (twice a day) until the end of the study (ie, up to Week 104 visit) or until early discontinuation from the trial.

The study will consist of 5 phases:

  • Screening Phase - up to 5 weeks
  • Randomized, Placebo-controlled, Double Blind Treatment Phase - Weeks 0 to 24
  • Active Treatment Phase - Week 24 to Week 52
  • Open-label Extension Phase - Week 52 to Week 104
  • Post-treatment Observational Follow-up Phase

    Time frame: Baseline and Week 16

    Percentage of participants with an American College of Rheumatology 20% (ACR20) response. A participant was a responder if the following 3 criteria for improvement from Baseline were met:

    • ≥ 20% improvement in 78 tender joint count;
    • ≥ 20% improvement in 76 swollen joint count; and
    • ≥ 20% improvement in at least 3 of the 5 following parameters:
    • Patient's self-assessment of pain (measured on a 0 to 10 unit numeric rating scale [NRS]);
    • Patient's global self-assessment of disease activity (measured on a 0 to 10 unit NRS);
    • Physician's global assessment of disease activity (measured on a 0 to 10 unit NRS);
    • Patient's self-assessment of physical function (Health Assessment Questionnaire - Disability Index [HAQ-DI]);
    • C-Reactive Protein (CRP) Those who withdrew early or who did not have sufficient data at Week 16 were counted as non-responders.

Secondary outcomes

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

    Time frame: Baseline and Week 24

    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. A higher score indicates worse physical functioning, and a negative change from baseline indicates improvement.

    • 28 swollen joint count, which do not include the DIP joints, the hip joint, or the joints below the knee;
    • C-reactive protein (CRP)
    • Patient's global assessment of disease activity. DAS28 (CRP) scores range from 0 to 9.4. 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. A higher value indicates higher disease activity, and a negative change from baseline indicates improvement.

  4. Change From Baseline in the Medical Outcomes Short Form Health Survey (SF-36) V2 Physical Function Domain Score at Week 24

    Time frame: Baseline and Week 24

    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). 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.

  5. Change From Baseline in the 36-item SF-36 Physical Component Summary Score at Week 24

    Time frame: Baseline and Week 24

    The SF-36 (v 2.0) 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 physical component summary (PCS) score includes the physical functioning, role physical, bodily pain, and general health domains. Minimum clinically important difference (MCID) for the scale scores, as well as the PCS and MCS, is defined as a 2.5-point improvement (increase) from baseline. The summary scores range from 0 to 100, with lower scores reflecting more disability, and higher scores reflecting less disability and better health. The 8 domains are regrouped into the PCS and MCS scores.

  6. Change From Baseline in the Duration of Morning Stiffness at Week 24

  7. Percentage of Participants With Improved Change in Severity of Morning Stiffness at Week 24

    Time frame: Baseline and Week 24

    Morning stiffness severity was the participant's assessment of how severe their morning stiffness was after first waking up in the morning, on average, during the previous week. The severity was recorded as none, mild, moderate, moderately severe, or very severe. The response of no improvement includes subjects who had no change or worsened. Improvement is defined as the change from baseline of a more severe assessment to less severe assessment.

    A TEAE is an AE with a start date on or after the date of the first dose of Investigational Product (IP). An AE is any noxious, unintended, or untoward medical occurrence, that may appear or worsen in a participant during the course of study.
