 the adhesion performance of ZTlido over the 12-hour administration period of the product. The study also investigated whether ZTlido met an FDA established adhesion performance benchmark of greater than or equal to 90% adhesion in greater than or equal to 90% of subjects in the study at the end of the administration period. At the end of the 12-hour administration period, over 90% of the subjects (49 out of the 54 subjects) maintained greater than or equal to 90% adhesion, with no adverse events reported during the study.

ZTlido Maintained Greater Than 90% Adhesion Over the 12-Hour Time Period

This study was considered the pivotal adhesion study for marketing approval and is summarized in the product label.

Head-to-Head Adhesion Study versus Lidoderm - SCI-LIDO-ADH-002

 19

We conducted an open label, single-treatment, three-period, single-application adhesion performance study in 44 healthy, human subjects to evaluate the adhesion performance of ZTlido compared to the adhesion performance of Lidoderm over a 12-hour administration period.

In this study, ZTlido demonstrated significantly superior mean adhesion scores compared to Lidoderm at 3, 5, 9 and 12 hours after application. ZTlido maintained a mean percent adhesion performance greater than 90% over the 12-hour administration period, while Lidoderm fell below 90% mean adhesion within three hours.

ZTlido Demonstrated Superior Adhesion Compared to Lidoderm

Head-to-Head Adhesion Study versus Mylan’s Generic - SCI-LIDO-ADH-003

We conducted an open-label, single-treatment, two-period, single-application adhesion performance study in 24 healthy, human subjects to evaluate the adhesion performance of ZTlido compared to the adhesion performance of a generic lidocaine patch 5% manufactured by Mylan over a 12-hour administration period. The purpose of this study was to compare the adhesion performance of ZTlido against a topical lidocaine product involving a non-aqueous formulation. We selected Mylan’s generic lidocaine patch as a comparator because it has similar product characteristics, including a non-aqueous polymer drug-in-adhesive system allowing for a thinner patch and a lower drug load as compared to Lidoderm.

In this study, ZTlido demonstrated significantly superior adhesion performance
