Trial Outcomes & Findings for A Study to Compare the Adhesiveness of 2 Different Rotigotine Patches Used for the Treatment of Parkinson's Disease (NCT NCT02230904)

NCT ID: NCT02230904

Last Updated: 2015-11-02

Results Overview

The assessment was performed according to the adhesion score adapted from the EMA draft guideline on quality of transdermal patches (EMA/CHMMP/QWP/911254/2011, 2012). * 0 = \> 95 - 100 % of the patch area adheres * 1 = \> 90 - 95 % of the patch adheres * 2 = \> 85 - 90 % of the patch adheres * 3 = \> 80 - 85 % of the patch adheres * 4 = \> 75 - 80 % of the patch adheres * 5 = \> 70 - 75 % of the patch adheres * 6 = ≥ 50 - 70 % of the patch adheres * 7 = \< 50 % of the patch adheres * 8 = Patch completely detached The recorded scores 6, 7, and 8 were combined in order to create a cumulative group "less than or equal to 70 % adhered or patch detachment" which was regarded as significant patch adhesion failure in the draft EMA guideline. The average of patches 1 and 2 is presented by Treatment Arm below.

PRIMARY outcome

Timeframe: Patch adhesiveness was measured after 24 hours (±1 hour) after previous patch application on Day 2, 3, 4 and 5

Population: Per Protocol Set (PPS), which was defined as all subjects who had at least 1 patch adhesiveness assessment after 24 hours of patch application by the investigator (or designee) for both treatments.

The assessment was performed according to the adhesion score adapted from the EMA draft guideline on quality of transdermal patches (EMA/CHMMP/QWP/911254/2011, 2012). * 0 = \> 95 - 100 % of the patch area adheres * 1 = \> 90 - 95 % of the patch adheres * 2 = \> 85 - 90 % of the patch adheres * 3 = \> 80 - 85 % of the patch adheres * 4 = \> 75 - 80 % of the patch adheres * 5 = \> 70 - 75 % of the patch adheres * 6 = ≥ 50 - 70 % of the patch adheres * 7 = \< 50 % of the patch adheres * 8 = Patch completely detached The recorded scores 6, 7, and 8 were combined in order to create a cumulative group "less than or equal to 70 % adhered or patch detachment" which was regarded as significant patch adhesion failure in the draft EMA guideline.

The assessment was performed according to the adhesion score adapted from the EMA draft guideline on quality of transdermal patches . Afterwards, EMA scores were translated into FDA/CDER scores: * 0 (\>95-100% of patch adheres) \>\> 0 (FDA/CDER) * 1 (\>90-95% of patch adheres) \>\> 0 (FDA/CDER) * 2 (\>85-90% of patch adheres) \>\> 1 (FDA/CDER) * 3 (\>80-85% of patch adheres) \>\> 1 (FDA/CDER) * 4 ( \>75-80% of patch adheres) \>\> 1 (FDA/CDER) * 5 (\>70-75% of patch adheres) \>\> 2 (FDA/CDER) * 6 (≥50-70% of patch adheres) \>\> 2 (FDA/CDER) * 7 (\<50 % of patch adheres) \>\> 3 (FDA/CDER) * 8 (Patch completely detached) \>\> 4 (FDA/CDER) Due to a slight mismatch of limits between FDA scores 0 and 1 as compared to EMA scores 1 and 2, the theoretical value of exactly 90 % of adh. fell into score 1 with the FDA scoring. A similar limit mismatch occured at exactly 75 %. These mismatches may have resulted in a slightly worse estimation of the adh. with the FDA score as compared to previous adh. studies.
