About this study

Official title: XELJANZ (REGISTERED) TABLETS 5MG SPECIAL INVESTIGATION (ALL-CASES SURVEILLANCE)

The objective of this Surveillance is to verify the following subject matters concerning Tofacitinib (Xeljanz) under general practice.

  1. Occurrence of adverse reactions, factors that may potentially affect safety and efficacy 2) Long-term safety (particularly, malignant tumors and serious infections) and efficacy

Occurrences of malignant tumors and serious infections will be compared with a control group.

Read the detailed description

All the patients whom an investigator prescribes the Xeljanz or Standard of Care for rheumatoid arthritis should be registered consecutively until the number of subjects reaches target number in order to extract patients enrolled into the investigation at random.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Treatment-related Adverse Events or Serious Treatment-related Adverse Events in Participants Who Received XELJANZ

    An adverse drug reaction (ADR) was any untoward medical occurrence attributed to XELJANZ in a participant who received XELJANZ. A serious adverse event/adverse drug reaction (SADR) was a treatment-related adverse event resulting in any of the following outcomes or deemed significant for any other reason: death; life-threatening experience (immediate risk of dying); initial or prolonged inpatient hospitalization; persistent or significant disability/incapacity; congenital anomaly. Relatedness to XELJANZ was assessed by the physician.

    Measured: 36 months

  2. Change in Disease Activity Based on Simplified Disease Activity Index (SDAI)

    The SDAI is the numerical sum of five outcome parameters: tender joint count (TJC) and swollen joint count (SJC) based on a 28-joint assessment, patient global assessment (PtGA) and physician global assessment (PGA) assessed on 0-10 cm VAS, and C-reactive protein (CRP) (mg/dL). SDAI is defined as follows: ≤3.3, disease remission; >3.3 to ≤11, low disease activity, >11 to ≤26, moderate disease activity; and >26, high disease activity. SDAI was assessed at each evaluation time point and mean change from the start of XELJANZ was calculated with the 95% CI.

    Measured: Baseline, 1, 6, 12, 24, 36 months

  3. Change in Disease Activity Score Based on 28-joints Count (DAS28)

    DAS28 is the numerical sum of 4 outcome parameters: tender joint count (TJC) and swollen joint count (SJC) based on a 28-joint assessment, PtGA assessed on 0-10 cm VAS, and the erythrocyte sedimentation rate (ESR) (millimeters per hour [mm/hour]). DAS28 is defined as follows: <2.6, disease remission; ≥2.6 to <3.2, low disease activity, ≥3.2 to ≤5.1, moderate disease activity; and >5.1, high disease activity. DAS28 was assessed at each evaluation time point and mean change from the start of XELJANZ was calculated with the 95% CI.

    Measured: Baseline, 1, 6, 12, 24, 36 months

Secondary outcomes (3)
  1. Occurrence of Serious Infection Events

    Comparison of time to serious infection between XELJANZ group and control group.

    Hazard ratio (unadjusted): Baseline characteristics are unadjusted Hazard ratio (adjusted 1): Adjusted by propensity score estimated by logistic regression Hazard ratio (adjusted 2): Adjusted by propensity score estimated by random forest Hazard ratio (adjusted 3): Adjusted by propensity score estimated by logistic regression (with upper limit of weighting) Hazard ratio (adjusted 4): Adjusted by propensity score estimated by random forest (with upper limit of weighting)

    Measured: 12 months

  2. Occurrence of Malignancy

    Comparison of time to malignancy between XELJANZ group and control group. The standard incidence ratio (SIR) was calculated using the general Japanese population as the reference population.

    Hazard ratio (unadjusted): Baseline characteristics are unadjusted Hazard ratio (adjusted 1): Adjusted by propensity score estimated by logistic regression Hazard ratio (adjusted 2): Adjusted by propensity score estimated by random forest Hazard ratio (adjusted 3): Adjusted by propensity score estimated by logistic regression (with upper limit of weighting) Hazard ratio (adjusted 4): Adjusted by propensity score estimated by random forest (with upper limit of weighting)

    Measured: 36 months

  3. Occurrence of Death

    Comparison of time to death between XELJANZ group and control group. The standardized mortality ratio (SMR) was calculated using the general Japanese population as the reference population.

    Hazard ratio (unadjusted): Baseline characteristics are unadjusted

    Measured: 36 months

Questions about this trial

What is this clinical trial studying?

An observational study of Rheumatoid Arthritis, run by Pfizer at 1 site in Japan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Japan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 26 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Treatment-related Adverse Events or Serious Treatment-related Adverse Events in Participants Who Received XELJANZ (time frame: 36 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01932372, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Oct 2024.
