Time Frame	At Week 16 only

Outcome Measure Data

Analysis Population Description

The Per-protocol analysis set (PPS) consists of patients who completed the study up to Week 16 and had no major protocol deviations or additional exclusion criteria up to and including Week 16.

Statistical Analysis 1

Statistical Analysis Overview	Comparison Group Selection	GP2017 Adalimumab, Humira ® Adalimumab
	Comments	[Not Specified]
	Type of Statistical Test	Equivalence
	Comments	Adjusted response rates were estimated using a logistic regression model including treatment, body weight strata, region and prior systemic therapy. The 95% CI for the rate difference was derived based on the normal approximation and standard error computed using the delta method.To conclude equivalent efficacy, the 95% CI had to be entirely within the interval [-18%, 18%].
Method of Estimation	Estimation Parameter	Risk Difference (RD)
	Estimated Value	1.8
