Recruitment details

This study was a multicenter study with 84 sites from the United States, Canada, Europe, Russia, Australia, South Africa and Taiwan.

Screening details

This study consisted of a 24-week randomized, double-blind, placebo-controlled phase, a 28-week randomized, double-blind active treatment phase and a 4-year open-label safety phase, for an overall study duration of 5 years.

Period 1 title

Placebo-controlled Phase (Week 0 - 24)

Is this the baseline period?

Yes

Allocation method

Randomised - controlled

Blinding used

Double blind

Roles blinded

Subject, Investigator, Monitor, Data analyst

Blinding implementation details

Blinding to treatment assignment was maintained at all sites until after the Week 52 database lock at Year 1, after all Week 52 analyses were completed and the results were released. At that time, active medication was provided. The blind was otherwise not to be broken during the study unless, in the opinion of the doctor, it was necessary to safely treat the subject.

Are arms mutually exclusive

Yes

Placebo

Arm description

Participants initially randomized to placebo tablets twice daily (BID) in the 24-week placebo-controlled phase. Participants who did not have at least 20% improvement in swollen and tender joint counts at Week (Wk) 16 were re-randomized to either 20 mg or 30 mg apremilast twice daily [(early escape (EE)].

Notes
[1] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left.
Justification: For all the arms, the number of subjects starting the subsequent periods were less than or equal to the number completing the preceding period, this is because not all subjects who completed the preceding period would enter the subsequent period.

Change from Baseline in Health Assessment Questionnaire- Disability Index (HAQ-DI) at Week 16

End point description

The Health Assessment Questionnaire - Disability Index 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. FAS; participants with a baseline value and at least 1 post-baseline value at or prior to Week 16 are included; Last observation carried forward (LOCF) imputation was used.

Statistical Analysis 1

Statistical analysis description

Pairwise comparisons (30 mg vs placebo and 20 mg vs placebo) were conducted conditional on the primary endpoint results. If the primary endpoint was statistically significant for both apremilast dose groups, pairwise comparisons for the HAQ-DI were to be evaluated at the 0.05 level using the Hochberg procedure. If only one apremilast dose was statistically significant, then only the comparison between that apremilast dose and placebo was conducted for the HAQ-DI score, at the 0.025 level.

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. Full analysis set; participants with a baseline value and at least 1 post-baseline value at or prior to Week 16 are included; LOCF was used.

End point title

Change from Baseline in the Disease Activity Score (DAS28) at Week 16

End point description

The DAS28 measures the severity of disease at a specific time and is derived from the following variables: - 28 tender joint count - 28 swollen joint count, which do not include the distal interphalangeal (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 approximately 10, with the upper bound dependent on the highest possible level of CRP. 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. Full analysis set; participants with a baseline value and at least 1 postbaseline value at or prior to Week 16 are included. LOCF was used.

Percentage of Participants with Dactylitis improvement ≥ 1 point at Week 16

End point description

Percentage of participants with pre-existing dactylitis whose dactylitis severity score improved by ≥ 1 after 16 weeks of treatment. Dactylitis is characterized by swelling of the entire finger or toe. Each digit on the hands and feet was rated as zero for no dactylitis or 1 for dactylitis present. The dactylitis score is the sum of the individual scores for each digit. The dactylitis severity score, ranging from 0 to 20, is the number of digits on the hands and feet with dactylitis present. Full analysis set; participants with a baseline dactylitis severity score > 0 (i.e., pre-existing dactylitis) are included; LOCF was used. Participants who did not have sufficient data (observed or imputed) for a determination of response status at Week 16 were counted as non-responders.

Percentage of Participants Achieving a Dactylitis Score of Zero at Week 16

End point description

Percentage of participants with pre-existing dactylitis whose dactylitis severity score improves to zero after 16 weeks of treatment. Dactylitis is characterized by swelling of the entire finger or toe. Each digit on the hands and feet was rated as zero for no dactylitis or 1 for dactylitis present. The dactylitis score is the sum of the individual scores for each digit. The dactylitis severity score, ranging from 0 to 20, is the number of digits on the hands and feet with dactylitis present. Full analysis set; participants with a baseline dactylitis severity score > 0 (i.e., pre-existing dactylitis) are included; LOCF was used. Participants who did not have sufficient data (observed or imputed) for a determination of response status at Week 16 were counted as non-responders.

The 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.

Percentage of Participants Achieving a MASES Score of Zero at Week 52

End point description

Percentage of participants with pre-existing enthesopathy whose MASES improves to 0 after 24 weeks. The Maastricht Ankylosing Spondylitis Enthesitis Score quantitates inflammation of the entheses (enthesitis) by assessing pain at the following entheses (sites where tendons or ligaments insert into the bone): 1st costochondral joints left/right; 7th costochondral joints left/right; posterior superior iliac spine left/right; anterior superior iliac spine left/right; iliac crest left/right; 5th lumbar spinous process; and the proximal insertion of the Archilles tendon left/right. The MASES, ranging from 0 to 13, is the number of painful entheses out of 13 entheses. Two-sided 95% confidence interval is based on the Clopper-Pearson method. Apremilast Subjects as Randomized/Re-randomized Population; subjects with a baseline value > 0 and who had sufficient data for a definitive response at Week 52 are included.

Percentage of Participants Achieving a Dactylitis Score of Zero at Week 52

End point description

Percentage of participants with pre-existing dactylitis whose dactylitis severity score improves to zero after 52 weeks. Dactylitis is characterized by swelling of the entire finger or toe. Each digit on the hands and feet was rated as zero for no dactylitis or 1 for dactylitis present. The dactylitis score is the sum of the individual scores for each digit. The dactylitis severity score, ranging from 0 to 20, is the number of digits on the hands and feet with dactylitis present. Two-sided 95% confidence interval is based on the Clopper-Pearson method. The Apremilast Subjects as Randomized/Re-randomized (AAR) Population; Participants with a baseline dactylitis severity score > 0 (i.e., pre-existing dactylitis) and who had sufficient data for a definitive determination of response status at Week 52 are included.

Number of Participants with Treatment Emergent Adverse Events During the Placebo-Controlled Phase

End point description

A Treatment Emergent Adverse Event (TEAE) is an AE with a start date on or after the date of the first dose of Investigational Product (IP). The severity of each adverse event (AE) and serious AE (SAE) was assessed by the investigator and graded based on a scale from Mild to Severe AEs. A serious adverse event (SAE) is any AE which: • Resulted in death • Was life-threatening • Required inpatient hospitalization or prolongation of existing hospitalization • Resulted in persistent or significant disability/incapacity • Was a congenital anomaly/birth defect • Constituted an important medical event; Safety population included all participants who were randomized and received at least one dose of IP.

Were there any global substantial amendments to the protocol? Yes

26 Jan 2011

1. Modification of protocol language for clarification. 2. Clarification of the language around contraception methods to ensure precise description of acceptable methods of contraception given the global nature of Celgene’s trials. In addition, a statement was added into the protocol to ensure that appropriate education regarding contraception methods was provided by the investigator to the subject. 3. Modification to protocol deleting annual chest radiographs allowing local treatment guidelines to dictate when chest radiographs were performed. 4. BSA involved by psoriasis added as study assessment. 5. Alignment of exclusion criteria related to past malignancies across the entire APR Phase 3 program that gave investigators responsibility for determining subject eligibility for previously successfully treated local lesions. 6. Modification of Reasons for Discontinuation to align with what was displayed in the Inform database.

10 Jun 2011

1. Provided correction regarding the Celgene Therapeutic Area Head of the study. 2. Addition of a serum pregnancy test at baseline for FCBP. 3. A clarification in Section 6.2, Contraception Education, which directed the investigator to Section 7.2 of the protocol where the specific details regarding acceptable contraception for this study were found. 4. A clarification in Section 6.6.4, Clinical Laboratory Evaluations, to indicate that a microscopic evaluation was to be performed on all urine samples. 5. Modification to Inclusion Criterion Number 14 – The Female Birth Control Inclusion Criterion was updated to clearly define single or multiple forms of contraception that were acceptable for this study. 6. Addition of a footnote to Inclusion Criterion Number 14 – The Female Birth Control Inclusion Criteria, which clarified that the female subject’s chosen form of contraception must be fully effective by the time the female subject received the first dose of study medication at randomization. 7. Modification to Inclusion Criterion Number 13 – Male Birth Control Inclusion Criteria, which clarified that male subjects must use a “male” latex or non-latex condom. 8. Descriptive text on how to record onset and end dates of SAEs on the SAE Report Form was deleted because it was no longer applicable.

20 Apr 2012

1. Provided updates to the contact information for the Medical Monitor of the study. 2. Modification of Section 4.1 Study Design, Section 8.2 Treatment Administration and Schedule, and Section 10.1 Overview regarding site and subject blinding until completion of the 52 Week double-blind phase. 3. Revision of Section 4.1 regarding the replacement of the SRP with an independent external DMC. 4. Modification of Section 4.2 Study Design Rationale, Section 9.1 Permitted Concomitant Medications and Procedures, and Section 9.2 Prohibited Concomitant Medications and Procedures to allow the use of topical therapy and/or phototherapy after the Week 52 study visit for worsening skin psoriasis. 5. Addition of a footnote to the Adverse Events row in Table of Events, Section 5, (Tables 1 and 2) which reminded investigators to perform vasculitis assessments and/or psychiatric evaluations as appropriate, when AEs were reported. 6. A revision of the Contraception Education in Section 6.2 and movement of footnote from Section 7.2 to Section 6.2. 7. Addition of Section 6.6.3.1 Vasculitis Assessment providing guidance to investigators. 8. Addition of Section 6.6.3.2 Psychiatric Evaluation to provide guidance to investigators for the management of subjects identified as having thoughts of suicide, attempted suicide, or having a major psychiatric illness. 9. Addition of Section 6.6.3.3 Risk Benefit for Long-term Active Treatment providing guidance to investigators regarding radiographs of symptomatic joints. 10. A change to the open-label IP packaging is described in Sections 6.9.1 and 8.4. 11. A note was added to Section 7.2, Inclusion Criterion 14, to refer investigators to Section 6.2, Contraception Education. 12. AE tables will summarize TEAEs only. 13. The term “CRF” (case report form) was changed to “eCRF” globally throughout the document to reflect that data is captured in this study in electronic case report form pages (eCRF).

03 Jul 2012

1. The assessment of the primary efficacy endpoint (ACR 20) was changed to Week 16 instead of Week 24. 2. Assessments of enthesitis and dactylitis (in subjects who present with these manifestations of PsA at baseline) were elevated to be secondary rather than exploratory outcome measures. 3. The secondary endpoints were to be assessed at Week 16, in addition to Weeks 24 and 52. 4. The order of secondary endpoints at Weeks 16, 24 and 52 was modified to coincide with the planned sequence of statistical testing. 5. The modified PsARC and EULAR response were added as secondary efficacy endpoints. 6. The ACR-N was added as an exploratory endpoint. 7. The health-related quality of life endpoints were to be assessed at Week 16, in addition to Weeks 24 and 52. 8. Modification of Section 9.1 Permitted Concomitant Medications to allow use of systemic corticosteroids and DMARDs after the Week 52 study visit for worsening arthritic symptoms of PsA 9. The statistical approaches for analysis of secondary endpoints were updated. 10. The statistical approaches for subgroup analyses were updated. 11. Citations were included to provide references for the modified PsARC and EULAR response that were added as secondary efficacy outcome measures in this amendment.

Were there any global interruptions to the trial? No
