Primary outcomes

  1. Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Event of Venous Thromboembolism (VTE) [Combined Baricitinib Dose Versus TNF Inhibitor]

    Time frame: From the first dose of study treatment up to 30 days after the last dose or the last study visit, whichever occurs first (approximately up to 6.1 years for JAJA and 5.3 years for JAJD participants)

    Time from first dose of study treatment to first event of VTE was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model. The analysis was based on pooled data from studies JAJA (NCT03915964) and JAJD (NCT04086745) and was stratified by study, with treatment group and randomization stratification factors (VTE history, age/Body Mass Index (BMI) combination, prior inadequate response or intolerance to a TNF inhibitor, and geographic region) as explanatory variables.

Secondary outcomes

  1. Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Event of Venous Thromboembolism (VTE) [Individual Baricitinib Dose Versus TNF Inhibitor]

    Time frame: From the first dose of study treatment up to 30 days after the last dose or the last study visit, whichever occurs first (approximately up to 6.1 years for JAJA and 5.3 years for JAJD participants)

    Time from first dose of study treatment to first event of VTE was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model.

  2. Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Arterial Thromboembolic Event (ATE) [Combined and Individual Baricitinib Dose Versus TNF Inhibitor]

    Time frame: From the first dose of study treatment up to 30 days after the last dose or the last study visit, whichever occurs first (approximately up to 6.1 years for JAJA and 5.3 years for JAJD participants)

    Time from first dose of study treatment to first ATE was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model. The analysis was based on pooled data from studies JAJA (NCT03915964) and JAJD (NCT04086745) and was stratified by study, with treatment group and randomization stratification factors (VTE history, age/BMI combination, prior inadequate response or intolerance to a TNF inhibitor, and geographic region) as explanatory variables.

  3. Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Major Adverse Cerebro-Cardiovascular Event (MACE) [Combined and Individual Baricitinib Dose Versus TNF Inhibitor]

    Time frame: From the first dose of study treatment up to 30 days after the last dose or the last study visit, whichever occurs first (approximately up to 6.1 years for JAJA and 5.3 years for JAJD participants)

    Time from first dose of study treatment to first MACE was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model. The analysis was based on pooled data from studies JAJA (NCT03915964) and JAJD (NCT04086745) and was stratified by study, with treatment group and randomization stratification factors (VTE history, age/BMI combination, prior inadequate response or intolerance to a TNF inhibitor, and geographic region) as explanatory variables.

  4. Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Malignancy (Excluding Nonmelanoma Skin Cancer [NMSC]) [Combined and Individual Baricitinib Dose Versus TNF Inhibitor]

    Time frame: From the first dose of study treatment up to 30 days after the last dose or the last study visit, whichever occurs first (approximately up to 6.1 years for JAJA and 5.3 years for JAJD participants)

    Time from first dose of study treatment to first malignancy (excluding NMSC) was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model. The analysis was based on pooled data from studies JAJA (NCT03915964) and JAJD (NCT04086745) and was stratified by study, with treatment group and randomization stratification factors (VTE history, age/BMI combination, prior inadequate response or intolerance to a TNF inhibitor, and geographic region) as explanatory variables.

  5. Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Opportunistic Infection [Combined and Individual Baricitinib Dose Versus TNF Inhibitor]

    Time from first dose of study treatment to first opportunistic infection was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model. The analysis was based on pooled data from studies JAJA (NCT03915964) and JAJD (NCT04086745) and was stratified by study, with treatment group and randomization stratification factors (VTE history, age/BMI combination, prior inadequate response or intolerance to a TNF inhibitor, and geographic region) as explanatory variables.

  6. Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Serious Infection [Combined and Individual Baricitinib Dose Versus TNF Inhibitor]

    Time frame: From the first dose of study treatment up to 30 days after the last dose or the last study visit, whichever occurs first (approximately up to 6.1 years for JAJA and 5.3 years for JAJD participants)

    Time from first dose of study treatment to first serious infection was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model. The analysis was based on pooled data from studies JAJA (NCT03915964) and JAJD (NCT04086745) and was stratified by study, with treatment group and randomization stratification factors (VTE history, age/BMI combination, prior inadequate response or intolerance to a TNF inhibitor, and geographic region) as explanatory variables.

Other outcomes

  1. Total Duration of Treatment Exposure for Combined Baricitinib Dose, Individual Baricitinib Dose and TNF Inhibitor

    Time frame: From the date of first dose of study drug up to the last dose (approximately up to 5.3 years)

    Duration of exposure was calculated as:

    • Baricitinib 2mg exposure = date of last baricitinib 2mg treatment - date of first baricitinib 2mg dose + 1. For participants who were rescued from baricitinib 2 mg to 4 mg, their drug exposure after rescue was censored and not counted as exposure to baricitinib 2mg.
    • Baricitinib 4mg exposure = date of last baricitinib 4mg treatment - date of first baricitinib 4mg dose + 1.

    TNF inhibitor exposure = date of last TNFi (adalimumab or etanercept) - date of first TNFi dose (adalimumab or etanercept) + 1, regardless of treatment cycling from adalimumab to etanercept or vice versa.

    • Total baricitinib exposure (2/4 mg) = date of last baricitinib (2mg or 4mg) treatment - date of first baricitinib (2mg or 4mg) dose + 1, regardless of rescue from baricitinib 2mg to baricitinib 4mg.

    Patient-years is calculated as sum of duration of exposure in days for all patients in dosing regimen divided by 365.25.
