Brief Summary

The purpose of this study is to learn about the safety and effects of the study medicine for the potential treatment of Psoriatic Arthritis (PsA). Psoriatic Arthritis is a joint swelling disease that can also affect the skin, nails and eyes. The study medicine is called Tofacitinib. This study is seeking participants who:

• Started taking tofacitinib alone or with other approved medicines (eg. methotrexate, leflunomide, sulfasalazine, apremilast) for PsA disease. We will only look at participants' who started tofacitinib after December 14, 2017.
• Have a 6-month follow-up visit (with a 3-month window) This is an observational study. Participants receiving Tofacitinib will be included to assess how well tofacitinib works. We will look at participants' demographic information and therapy history. We will also monitor participants' disease progression before and 6 months after treatment. We will examine the experiences of people receiving the study medicine. This will help us determine if the study medicine is safe and effective.

Outcome Measures

Primary Outcomes (19)

• Change From Baseline to 6 Months in Tender Joint Count (68)

  Tender joint count (TJC) 68 is a method of assessing joint inflammation. Number of tender joints was determined by examining 68 joints and identifying the joints that were painful under pressure or to passive motion. The joints examined included the temporomandibular (n = 2), sternoclavicular (n = 2), acromioclavicular (n = 2), shoulder (n = 2), elbow (n = 2), wrist (n = 2), metacarpophalageal (n = 10), interphalangeal of thumb (n = 2), distal interphalangeal (n = 8), proximal interphalangeal (n =8), hip (n = 2), knee (n = 2), ankle mortise (n = 2), ankle tarsus (n = 2), metatarsophalangeal (n = 10), interphalangeal of great toe (n = 2), and proximal/distal interphalangeal of the toes (n = 8). Change from baseline in TJC at 6 months after tofacitinib treatment initiation was reported in this outcome measure. Baseline was defined as the date of tofacitinib treatment initiation anytime in between 14 December 2017 to 31 August 2023.

  Baseline, 6 months after tofacitinib initiation (anytime in between 3 to 9 months); data collected and evaluated for over 23.5 months in this retrospective observational study

• Change From Baseline to 6 Months in Swollen Joint Count (66)

  Joint swelling was defined as soft tissue swelling that was detectable along the joint margins. Swollen Joint Count (SJC) was determined by examination of 66 joints and identifying when swelling was present. The joints examined included the temporomandibular (n = 2), sternoclavicular (n = 2), acromioclavicular (n = 2), shoulder (n = 2), elbow (n = 2), wrist (n = 2), metacarpophalangeal (n = 10), interphalangeal of thumb (n = 2), distal interphalangeal (n = 8), proximal interphalangeal (n = 8), knee (n = 2), ankle mortise (n = 2), ankle tarsus (n = 2), metatarsophalangeal (n = 10), interphalangeal of great toe (n = 2), and proximal/distal interphalangeal of the toes (n = 8). Change from baseline in SJC at 6 months after tofacitinib treatment initiation was reported in this outcome measure. Baseline was defined as the date of tofacitinib treatment initiation anytime in between 14 December 2017 to 31 August 2023.

• Percentage of Participants With Percent Body Surface Area Score of 0% at 6 Month Follow-up Visit

  Four body regions were evaluated: head and neck, upper limbs, trunk (including axillae and groin) and lower limbs (including buttocks). Scalp, palms and soles were excluded. BSA was calculated using handprint method. Number of handprints (size of participant's full palmer hand) fitting in affected area of body region was counted. Maximum number of handprints were 10 for head and neck, 20 for upper limbs, 30 for trunk and 40 for lower limbs. Surface area of body region equivalent to 1 handprint: 1 handprint = 10 percent (%) for head and neck, 5% for upper limbs, 3.33% for trunk and 2.5% for lower limbs. Percent BSA for a body region = total number of handprints in a body region \* % surface area equivalent to 1 handprint. Overall % BSA for an individual: arithmetic mean of % BSA of all 4 body regions, ranged from 0 to 100%. Higher % BSA = greater severity of psoriasis. Percentage of participants with % BSA score of 0% at 6-month follow-up visit were reported in this outcome measure.
