Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Characterization of adhesion 5 minutes prior to removal by the adhesion assessment by site staff with EFTS marked by site staff	Assessment/estimation by site staff with marked TK-254RX by site staff: A listing of individual values of percentage will be presented per time point and subject.; Descriptive statistics (Number, arithmetic mean, standard deviation, median, minimum and maximum) will be presented per time point for adhesion marker assessment by site staff with marked TK-254RX by site staff (percentage values).	5 minutes prior to removal,
Secondary	Characterization of adhesion by visual estimation of subjects	Visual Assessment by subjects with a 5 point-scale: A listing of classification (=90%, =75% to <90%, =50% to <75%, >0% to <50%, completely detached) of adhesion per time point and subject will be given.	before bedtime (-1hour), after waking up (+1hour), 5minutes prior to removal
Secondary	Characterization of adhesion by the adhesion assessment by site staff with EFTS marked by subjects	Assessment/estimation by site staff with marked TK-254RX by subject: A listing of individual values of percentage will be presented per time point and subject.; Descriptive statistics (Number, arithmetic mean, standard deviation, median, minimum and maximum) will be presented per time point for adhesion marker assessment by site staff with marked TK-254RX by subject (percentage values).	before bedtime (-1hour), after waking up (+1hour), 5minutes prior to removal
Secondary	Comparison of the adhesion assessments between subjects and study staff	Three different adhesion assessments at 24hours as below will be performed. i. Visual assessment scale by subject ii. Assessment scale by site staff with marked TK-254RX by subject iii. Assessment scale by site staff with marked TK-254RX by site staff Comparison of i versus iii: the marked TK-254RX %-scale from iii are transformed into the 5-point scale (= 90%, =75% to <90%, =50% to <75%, >0% to <50%, completely detached); then the 5-point scale assessments from i and iii are compared via 5x5-cross tabulations and Spearman rank correlations.; Comparison of ii versus iii: the marked TK-254RX %-scale from ii and iii are transformed into the 5-point scale (= 90%, =75% to <90%, =50% to <75%, >0% to <50%, completely detached); then the 5-point scale assessments from ii and iii are compared via 5x5-cross tabulations and Spearman rank correlations.	5minutes prior to removal
Secondary	Characterization of local tolerability during treatment	The skin will be visually checked and palpated for skin irritation or sensitization by trained personnel.; Local tolerability will be assessed by the Investigator according to FDA recommendations.	within 5 minutes after removal of each patch
