| Change From Baseline in the Composite Score of BME, Synovitis, and Tenosynovitis Assessed by PsAMRIS at Week 24 | PsAMRIS is a validated MRI scoring system that assesses metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints of fingers 2 to 5 of the most affected hand (the hand with the greater inflammatory burden of swollen joints and/or dactylitis). Synovitis, flexor tenosynovitis, and bone marrow edema were scored from 0 (none/normal) to 3 (severe) at each joint. The total scores for synovitis and tenosynovitis range from 0 to 36 and the total score for BME ranges from 0 to 72 since both proximal and distal regions of each joint were scored. The PsAMRIS composite inflammation score is calculated as: BME score + 2 × synovitis score + 2 × tenosynovitis score, and ranges from 0 (normal) to 216 (severe). A negative change from baseline indicates improvement. This endpoint was analyzed using a mixed-effects model for repeated measures (MMRM) with change from baseline as the dependent variable; baseline value, scanner type and time as independent variables. | Baseline and week 24 |

| Baseline and week 48 |
| Change From Baseline in the Composite Score of BME and Synovitis Assessed by PsAMRIS at Weeks 24 and 48 | PsAMRIS is a validated MRI scoring system that assesses metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints of fingers 2 to 5 of the most affected hand (the hand with the greater inflammatory burden of swollen joints and/or dactylitis). Synovitis and bone marrow edema were each scored from 0 (none/normal) to 3 (severe) at each joint. The total score for synovitis ranges from 0 to 36 and the total score for BME ranges from 0 to 72 since this is scored at both proximal and distal regions of each joint. The PsAMRIS composite score of BME and synovitis is calculated as: BME score + 2 × synovitis score. The score ranges from 0 (normal) to 144 (severe). A negative change from baseline indicates improvement. This endpoint was analyzed using a MMRM including change from baseline of composite score of BME and synovitis as dependent variable; baseline value, scanner type and time as independent variables. | Baseline and weeks 24 and 48 |

Synovitis, flexor tenosynovitis, and bone marrow edema were each scored from 0 (none/normal) to 3 (severe) at each joint. Periarticular inflammation was scored 0 (absent) or 1 (present) separately at volar and dorsal aspects of the same 12 joints. The scores for synovitis and tenosynovitis range from 0 to 36, the score for BME is from 0 to 72 and the periarticular inflammation score is from 0 to 24. The PsAMRIS total inflammation score is calculated as: BME score + 2 × synovitis score + 2 × tenosynovitis score + 3 × periarticular inflammation, and ranges from 0 (normal) to 288 (severe). A negative change from baseline indicates improvement. This endpoint was analyzed using a MMRM with change from baseline score as dependent variable; baseline value, scanner type and time as independent variables. | Baseline and weeks 24 and 48 |
| Change From Baseline in Bone Marrow Edema Assessed by PsAMRIS at Weeks 24 and 48 | Bone marrow edema (BME) is a buildup of fluid inside the bones. The OMERACT PsAMRIS scoring system assesses BME at the proximal and distal regions of MCP, PIP, and DIP joints of fingers 2 to 5 of the most affected hand. BME is assessed on a scale of 0-3 based on the proportion of bone with edema, compared to the assessed bone volume (articular surface to a depth of 1 cm), judged on all available images; where 0: no edema; 1: 1-33% of bone edema; 2: 34-66% of bone edema; 3: 67-100% of bone edema. The overall score ranges from 0 (none) to 72 (severe). A negative change from baseline indicates improvement. This endpoint was analyzed using a MMRM with change from baseline BME score as dependent variable; baseline value, scanner type and time as independent variables. | Baseline and weeks 24 and 48 |

Thirty-three entheseal sites were assessed for soft tissue inflammation (STI) and 34 sites for osteitis, including the shoulder, pelvis, knees and feet, each on a scale from 0 (none) to 3 (severe). The Total Peripheral Enthesitis Inflammation score is calculated by adding up all the enthesitis (STI and osteitis) scores and ranges from 0 to 201, with higher scores reflecting greater disease severity. A negative change from baseline indicates improvement. WB-MRI endpoints were analyzed using a MMRM including change from baseline as dependent variable; baseline value, scanner type and time as independent variables. | Baseline and weeks 24 and 48 |
| Change From Baseline in the WB-MRI Peripheral Joints Inflammation Index at Weeks 24 and 48 | Joint inflammation was assessed by whole body MRI according to the OMERACT MRI-WIPE scoring system. Eighty-three peripheral joints were assessed for synovitis and 96 sites for osteitis at the shoulder, hands, pelvis, knees and feet on a semiquantitative scale from 0 (none) to 3 (severe). The Peripheral Joint Inflammation score is calculated by adding up all the joint (synovitis and osteitis) scores and ranges from 0 to 537, with higher scores reflecting greater disease severity. A negative change from baseline indicates improvement. WB MRI endpoints were analyzed using a MMRM including change from baseline as dependent variable; baseline value, scanner type and time as independent variables. | Baseline and weeks 24 and 48 |
| Change From Baseline in the WB-MRI Total Peripheral Inflammation Index at Weeks 24 and 48 | Inflammation in joints (arthritis) and at entheses (enthesitis) were assessed separately for soft tissues (synovitis at joints, soft tissue inflammation at entheses) and bone (osteitis) by whole body MRI according to the OMERACT MRI-WIPE scoring system. Each entheseal and joint was scored on a scale from 0 (none) to 3 (severe). The total peripheral inflammation index is the sum of peripheral enthesitis and peripheral joints inflammation index scores, and ranges from 0 to 738, with higher scores reflecting greater disease severity. A negative change from baseline indicates improvement. WB MRI endpoints were analyzed using a MMRM including change from baseline as dependent variable; baseline value, scanner type and time as independent variables. | Baseline and weeks 24 and 48 |
| Change From Baseline in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at Weeks 24 and 48 | BASDAI is a composite score based on a self-administered survey of six questions with each answered on a 0 to 10 NRS. The 6 questions assess the five major symptoms relevant to spondyloarthropathies: 1) fatigue; 2) spinal pain; 3) peripheral joint pain/swelling; 4) areas of localized tenderness; 5a) morning stiffness severity upon wakening; 5b) morning stiffness duration upon wakening. To give each of the 5 symptoms equal weighting, the mean of the two scores relating to morning stiffness (questions 5 and 6) is taken. The final BASDAI score is calculated as the mean of the 5 items. The BASDAI score ranges from 0 to 10, with higher scores reflecting greater disease activity. A negative change from baseline indicates improvement. BASDAI was analyzed in participants deemed to have PsA spondylitis by the investigator and with BASDAI item 2 score ≥ 4 at baseline). | Baseline and weeks 24 and 48 |
| Change From Baseline in the Psoriatic Arthritis Impact of Disease 12 Domain Questionnaire (PsAID-12) at Weeks 24 and 48 | The PsAID consists of 12 physical and psychological domains: pain, fatigue, skin, work and/or leisure activities, function, discomfort, sleep, coping, anxiety, embarrassment and/or shame, social life, and depression. Each domain is scored on a NRS rom 0 to 10. The final score is derived as a weighted sum of each domain score, divided by 20, and has a range from 0 (best status) to 10 (worst status). A negative change from baseline indicates improvement. | Baseline and weeks 24 and 48 |
| Number of Participants With Treatment-emergent Adverse Events (TEAEs) | A TEAE is any adverse event (AE) that began or worsened on or after the first dose of apremilast and no later than 28 days after the last dose. A serious adverse event is any AE occurring at any dose that:
For each AE, the Investigator assessed the severity/intensity of the event as mild, moderate, or severe (symptoms causing severe discomfort/pain, interference with daily activities, and requiring medical, surgical or drug therapy). The Investigator also assessed whether each event was suspected to be related to study drug based on whether there was evidence to suggest a causal relationship. | From first dose of study drug up to 28 days after last dose; up to 52 weeks. |

| Secondary | Change From Baseline in the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) at Weeks 24 and 48 | BASDAI is a composite score based on a self-administered survey of six questions with each answered on a 0 to 10 NRS. The 6 questions assess the five major symptoms relevant to spondyloarthropathies: 1) fatigue; 2) spinal pain; 3) peripheral joint pain/swelling; 4) areas of localized tenderness; 5a) morning stiffness severity upon wakening; 5b) morning stiffness duration upon wakening. To give each of the 5 symptoms equal weighting, the mean of the two scores relating to morning stiffness (questions 5 and 6) is taken. The final BASDAI score is calculated as the mean of the 5 items. The BASDAI score ranges from 0 to 10, with higher scores reflecting greater disease activity. A negative change from baseline indicates improvement. BASDAI was analyzed in participants deemed to have PsA spondylitis by the investigator and with BASDAI item 2 score ≥ 4 at baseline). | Full analysis set participants deemed to have PsA spondylitis by the investigator and with BASDAI item 2 score ≥ 4 at baseline, and with available data at each time point. | Posted | Mean | Standard Deviation | score on a scale | Baseline and weeks 24 and 48 |

The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results after completion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
