- Primary Outcome Measures
Name Time Method Main Objective: The primary objective of the study is to assess the ability of different dupilumab dose regimens, administered as monotherapy, to maintain the treatment response achieved after 16 weeks of initial treatment with dupilumab monotherapy compared to placebo.;Secondary Objective: The secondary objective of the study is to assess the safety of different dupilumab dose regimens administered as monotherapy over a period of 36 weeks.;Primary end point(s): • Difference between current study baseline and week 36 in percent change in EASI from the baseline of the initial treatment study (R668-<br>AD-1334 or R668-AD-1416)<br>• Percent of patients maintaining EASI-75 at week 36 in the subset of patients with EASI-75 at baseline.<br>;Timepoint(s) of evaluation of this end point: The primary endpoint will be determined at week 36.
- Secondary Outcome Measures
Name Time Method Secondary end point(s): • Percent of patients with an increase of =2 points in IGA from baseline to week 36, in the subset of patients with IGA (0,1) at baseline<br>• Percent of patients with IGA(0,1) at week 36 in the subset of patients with IGA(0,1) at baseline<br>• Percent of patients whose peak Pruritus NRS increased by 3 or more points from baseline to week 36 in the subset of patients with peak Pruritus NRS =7 at baseline<br>;Timepoint(s) of evaluation of this end point: The secondary endpoints will be determined from baseline to week 36.
