A total of approximately 500 patients with active psoriatic arthritis in an estimated 80 to 100 trial centers are to be enrolled. Selection of centers will be made by the sponsor's medical section. To increase the quality of the data and to reduce distribution of the data collected, centers to be included will be those which can enroll at least 5 patients. Care will be taken to ensure a balanced regional distribution. The proposed observation period for the trial is approx. 52 weeks per patient. Estimated patient enrolment is also 52 weeks. The duration of the follow-up period will be extended from approx. 52 weeks to approx. 100 weeks to gain further information about the long-term use of Otezla®. For this extension of the follow-up period 2 new visits (visits 6 and 7) are proposed.Thus, proposed duration from first patient in (FPI) to last patient out (LPO) is 36 months-

| Measure | Description | Time Frame |
|---|---|---|
| Percentage of patients with an improvement of ≥ 1 points on the Physician's Global Assessment (PGA) scale on visit 3 compared to baseline on the Physician's Global Assessment scale (PGA; scale from 0-4) | Physician's global assessment (PGA) will be measured on a VAS scale ranging from 0 to 4. Primary endpoint is the percentage of patients with an improvement of minimum 1 point on this VAS scale after about 6 months (visit 3) | Up to approximately 7 months |
| Measure | Description | Time Frame |
|---|---|---|
| Percentage of patients with an improvement of ≥ 1 points on the Patient Global Assessment (PaGA) scale on visits 1 to 7 compared to baseline | Patient Global Assessment will be measured on a VAS scale ranging from 0 to 5. The percentage of patients with an improvement of minimum 1 point will be measured throughout the study. | Up to approximately 104 weeks |
