Detailed Description
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 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.

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.

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.

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.
Improvement is defined as the change from baseline of a more severe assessment to less severe assessment.

Number of Participants With Treatment Emergent Adverse Events (TEAE) During the 24 Week Placebo Controlled Phase
Time Frame: Date of first dose of study drug to Week 24; median duration of exposure during placebo controlled phase was 24.14 weeks
|
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.
It may be a new intercurrent illness, a worsening concomitant illness, an injury, or any concomitant impairment of the participant's health, including laboratory test values regardless of etiology.
Any worsening (ie, any clinically significant adverse change in the frequency or intensity of a preexisting condition) was considered an AE.
A serious AE (SAE) is any untoward adverse event that is fatal, life-threatening, results in persistent or significant disability or incapacity, requires or prolongs existing in-patient hospitalization, is a congenital anomaly or birth defect, or a condition that may jeopardize the patient or may require intervention to prevent one of the outcomes listed above.
