Brief Summary:
This is an open-label, single-arm, randomized, evaluator-blinded repeat insult patch testing (RIPT) study wherein test product is applied under an occlusive dressing to the upper back or arm continuously and repeatedly to the same site for a period of 21 days.

Condition or disease Intervention/treatment Phase
Healthy Volunteers Drug: PBI-100 Topical Cream Drug: Positive Control - Sodium laurel sulfate (SLS) Other: PBI-100 Topical Cream, Vehicle Other: Negative Control Phase 1

Detailed Description:
This is an open-label, single-arm, randomized, evaluator-blinded repeat insult patch testing (RIPT) study wherein test product is applied under an occlusive dressing to the upper back or arm continuously and repeatedly to the same site for a period of 21 days. Three concentrations of PBI-100 Topical Cream and vehicle (placebo cream) will be applied to the skin of each subject. In addition, one site will be treated with a positive control and another site will be treated with a plain cotton cloth patch and will serve as a negative control.

Official Title: A 21 Day, Randomized, Controlled Study to Evaluate the Skin Irritation Potential of PBI-100 Topical Cream in Healthy Participants Using a Cumulative Irritant Patch Test Design
Actual Study Start Date : April 12, 2021
Actual Primary Completion Date : May 3, 2021
Actual Study Completion Date : May 3, 2021

Arm Intervention/treatment
Experimental: Cumulative Irritation Test
Participants will receive topical applications of three concentrations of PBI-100 Topical Cream, one application of vehicle, one application of sodium lauryl sulfate as a positive control and one application of a plain patch as a negative control daily (excluding weekends) for 21 days or 15 applications.
Drug: PBI-100 Topical Cream
A dose of approximately 560 ug (approximately 0.4 mL of each of the three concentrations to 3 different sites) of PBI-100 was applied daily (excluding weekends) to the skin test sites.

Drug: Positive Control - Sodium laurel sulfate (SLS)
Approximately 0.4 mL of 0.25% SLS was applied daily (excluding weekends) as a positive control test site.
Other Name: SLS

Other: PBI-100 Topical Cream, Vehicle
Approximately 0.4 mL of 0% placebo cream was applied daily (excluding weekends) as a positive control test site.

Other: Negative Control
A blank patch was applied daily (excluding weekends) as a negative control test site.




Primary Outcome Measures :
  1. Irritation Potential [ Time Frame: 21 days ]
    Irritation potential based on the Cumulative Irritation Index (CII)
