Further study details as provided by Galderma:

Primary Outcome Measures:
  • Duration of Anesthesia(Minutes) [ Time Frame: From T0 (product removal) up to T8 hours after product removal ]
    Onset and end of anesthesia are evaluated by Pinprick tests. Duration of anesthesia is calculated as: difference between onset and end of anesthesia (minutes).

Secondary Outcome Measures:
  • Adverse Events [ Time Frame: During the study ]
    Incidence of adverse events was to be reported during the study period

Enrollment: 30
Study Start Date: May 2012
Study Completion Date: May 2012
Primary Completion Date: May 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: lidocaine 7% and tetracaine 7% Drug: Lidocaine 7% + Tetracaine 7% cream
Study drug will be applied with a different application time to one side of the face and anterior thigh according to the randomization list.

Detailed Description:

Subjects will have 4 target zones defined; 2 on the face and 2 on the anterior thighs. Upon inclusion into the study, subjects will have the study drug applied with a different application time to one side of the face and anterior thigh according to the randomization. After the completion of the application process, study drug on both sides of the face and on both anterior thighs will be removed by peeling.

After drug removal, the duration of anesthetic effect of the study drug will be tested using a pinprick test. Five (5) pinpricks using a 21-gauge needle will be performed at the 4 target zones (each side of the face and both anterior thighs). The pinprick test will be repeated up to 8 hours after drug removal. There will be a total of 20 post drug removal pinprick test completed.
