Phase: Phase 1
Study type: Interventional
Primary purpose: Treatment
Allocation: Randomized
Intervention model: Parallel Assignment
Intervention model description: The study consist of an Induction phase, where treatments (MC2-01 Cream, MC2-01 vehicle) were applied to 2 test sites each (n=4), followed by irradiation/non-irradiation and evaluation 24, 48 or 72 hours post-irradiation. This was repeated in total 6 times over an 3 weeks period. The induction phase was followed by a challenge phase, where treatments (MC2-01 Cream, MC2-01 vehicle) were applied to each two naive test sites and another naive test site was untreated. 24 hours of product application, one of each test sites (MC2-01 Cream, MC2-01 vehicle) + the untreated test site were irradiated. Possible changes in dermal reaction (erythema and edema) was evaluated at all 5 test sites, 24, 48 and 72 hours post-irradiation.
Masking: Double (Participant, Outcomes Assessor)
Masking description: The tests sites (M2-01 Cream, MC2-01 vehicle, control) will not be blinded to the site staff involved in the preparation/application and removal of treatments. The subjects and the trained assessor will be blinded to the IPs and treatment allocation

Summary:

      This trial is a 6-week, Randomized study evaluating the potential of MC2-01 Cream to induce a
      photoallergic skin reaction in Healthy subjects, using a controlled photopatch test design.
