Korean Post-marketing Surveillance for Xeljanz XR

Pfizer200 enrolled

Overview

Xeljanz XR extended-release tablets 11 mg (Tofacitinib citrate) is a drug subject to the risk management plan in accordance with Article 4-1-11 of the "Regulation on Safety of Medicinal Products, etc." in Korea. As part of additional pharmacovigilance activity, this Post-marketing Surveillance (PMS) was planned to evaluate safety and effectiveness of Xeljanz XR under routine clinical practice. At least 200 patients with Rheumatoid Arthritis, Psoriatic Arthritis, or Ankylosing Spondylitis who were treated with Xeljanz XR will be enrolled about four years.

This is a open-label, non-comparative, non-interventional, prospective, and multi-center study to further evaluate the safety and effectiveness of Xeljianz XR in routine clinical practice in Korea. Safety is the primary interest of this study, which will be assessed based on adverse events (AEs) that occur during the 6 months from the first dose of Xeljanz XR. The efficacy endpoints will be the modified Disease Activity Score using 28 joint counts (DAS28) change from baseline, European League Against Rheumatism (EULAR) response, and American College of Rheumatology 20% improvement criteria (ACR20) response after treatment.

Outcomes

Primary Outcomes

Number of Participants With Treatment Emergent Adverse Events (AEs)

AE is any untoward medical occurrence attributed to study drug in a participant who received study drug. Serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to end of this PMS after last dose that were absent before treatment or that worsened relative to pretreatment state. Relatedness to Xeljanz XR was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category.

Time frame: Maximum of 52 weeks from the time of initial administration of Xeljanz XR

Secondary Outcomes

Change from baseline in Disease Activity Score based on 28-joints Count (DAS28)

DAS28, a modified version of the original Disease Activity Score (DAS), is a quantitative measure of disease activity used to monitor the treatment of RA.
