Observational Study To Assess The Effectiveness and Treatment Adherence Of Tofacitinib of Ulcerative Colitis In Clinical Practice In Sweden
- Registration Number
- NCT04338204
- Lead Sponsor
- Pfizer
- Brief Summary
This is a prospective observational study using data from an existing, ongoing National Swedish registry (SWIBREG). This study is designed to assess the effectiveness and treatment adherence of tofacitinib on clinical disease activity parameters in patients with ulcerative colitis in Swedish clinical practice. The study will also assess treatment adherence of tofacitinib using the Swedish Prescribed Drug Register.

- The assignment of the patient to tofacitinib is not decided in advance by the protocol but falls within clinical practice and the prescription of the medicine is done according to the SmPC and is clearly separated from the decision to include the patient in the study.
- The patient must sign the informed consent before enrollment in the study. The informed consent permits extraction of data from SWIBREG at baseline and during the duration of the study. For patients not registered in SWIBREG, they must complete all SWIBREG consents and registration at the time of treatment initiation. Evidence of a personally signed and dated informed consent document indicating that the patient (or a legally acceptable representative) has been informed of all pertinent aspects of the study.
- Patients, male or female, must be 18 years old or above.
- The patient must have active disease as confirmed by fecal calprotectin >250 mg/kg or endoscopic assessment corresponding to a Mayo endoscopic subscore ≥2 not more than 4 weeks prior onset to the initiation of tofacitinib treatment. This inclusion criteria applies also to patients that have already been enrolled in the study.
- The patient is enrolled in a clinical trial in which the treatment of ulcerative colitis is dictated by a study protocol. If the patient is participating in another ongoing observational study (non-interventional), the patient may be included in this observational study.
- Patients that fulfill any of the contraindications according to the latest version of the SmPC. Any SmPC label updates will be communicated to all study sites.
- For whatever reason the physician feels the patient unsuitable to participate in the study.
