A Phase 3b, Multicenter, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Evaluate the Efficacy and Safety of Apremilast (CC-10004) Monotherapy in Subjects With Active Psoriatic Arthritis

The purpose of this study is to determine whether apremilast is safe and effective for
treating patients with psoriatic arthritis.

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:

1. Screening Phase - up to 5 weeks

2. Randomized, Placebo-controlled, Double Blind Treatment Phase - Weeks 0 to 24

3. Active Treatment Phase - Week 24 to Week 52

4. Open-label Extension Phase - Week 52 to Week 104

5. Post-treatment Observational Follow-up Phase

one day prior to their baseline visit (ie, Visit 2, Day 0) 11. Subjects who have been
previously treated with leflunomide will require a 12-week washout or treatment with
the cholestyramine, per leflunomide prescribing label (ie. 8 g cholestyramine 3 times
daily for 11 days.

washout prior to randomization to participate in the study 13. If taking oral
corticosteroids, must be on a stable dose of prednisone less than or equal to 10

on stable dose for at least 30 days prior to baseline visit (ie, Day 0) and until
they have completed the Week 24 study visit.

15. Must meet the following laboratory criteria:

greater than 2 times the ULN, one repeat test is allowed during the screening
period.

- Total bilirubin less than or equal to 2 mg/dL (less than or equal to 34 μmol/L)
or Albumin greater than LLN. If initial test result is greater than 2 mg/dL, one
repeat test is allowed during the screening period.

- Hemoglobin at least 9 g/dL (at least 5.6 mmol/L)

- Hemoglobin A1c less than or equal to 9.0% 16. All females of childbearing
potential (FCBP) must use one of the approved contraceptive options as described
below while on investigational product and for at least 28 days after
administration of the last dose of the investigational product.

At the time of study entry, and at any time during the study when a female subject of
childbearing potential's contraceptive measures or ability to become pregnant changes, the
investigator will educate the subject regarding contraception options and the correct and
consistent use of effective contraceptive methods in order to successfully prevent
pregnancy.

Females of childbearing potential must have a negative pregnancy test at Screening and
Baseline. All FCBP subjects who engage in activity in which conception is possible must
use one of the approved contraceptive options described below:
