Primary

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

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]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.
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]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.

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]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.
Pooled JAJA and JAJD: Time From First Dose of Study Treatment to First Opportunistic Infection [Combined and Individual Baricitinib Dose Versus TNF Inhibitor]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 opportunistic infection was evaluated using hazard ratio as the measure of treatment effect, estimated from Cox proportional hazards regression model.
