Brief Summary:
This is a single center, randomized, controlled, within subject comparison, single dose study to determine the sensitization potential of SM04755 solution on normal skin under semi-occlusive patch conditions.

Condition or disease Intervention/treatment Phase
Tendinopathy Drug: SM04755 Other: Vehicle Other: White Petrolatum Other: Sodium lauryl sulfate Phase 1

Detailed Description:
This Phase 1, Repeat Insult Patch Test (RIPT) study is a single-center study of topical SM04755 solution repetitively applied to skin of healthy volunteers. This study will assess the potential of the Test Materials to induce contact sensitization as measured by treatment emergent adverse events (TEAEs), Reaction Grade and Investigator assessment of irritation and sensitization.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 223 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Masking Description: The Principal Investigator, subjects, and the site personnel who will be performing Reaction Grade assessments will be blinded to the Test Material identity, with the exception of the Positive Control.
Primary Purpose: Treatment
Official Title: A Phase 1, Single-Center, Repeat Insult Patch Test (RIPT) Study Evaluating the Sensitization Potential of Topical SM04755 Solution
Actual Study Start Date : September 11, 2017
Actual Primary Completion Date : November 17, 2017

Primary Outcome Measures :
  1. Contact sensitization potential of Test Material as measured by Treatment emergent [ Time Frame: Baseline to Day 40 (or through the observation period for TEAEs) ]
  2. Contact sensitization potential of Test Material as measured by Reaction Grade [ Time Frame: Baseline to Day 38-40 ]
    Reaction Grade is measured on a 5-point scale from zero to four (zero = no sign of irritation and 4 = Erythema with edema and blistering)

  3. Contact sensitization potential of Test Material as measured by Investigator assessment of irritation and sensitization [ Time Frame: Baseline to Day 40 ]
