Blue Light for Treating Eczema

Monocenter, randomized, intraindividual, open label, exploratory study comparing 4 weeks of treatment with 453nm blue light with no treatment in patients with Eczema. Patients will be screened up to 28 days before start of treatment. During the screening visit, the purpose and procedures of the study will be explained to potential patients and informed consent will be obtained. In addition, fungal superinfection of the target area will be examined using direct preparations and mycology cultures. At the baseline visit, patients with Eczema will be determined and all inclusion and exclusion criteria will be assessed. For eligible patients, two comparable treatment areas will be randomized to treatment with blue light (target area) or to serve as untreated control area. After randomization, patients will receive treatment of the target area with 3 applications per week at the investigational site for a total treatment period of 4 weeks. During those 4 weeks, safety and effectiveness assessments will be performed at weekly intervals. After end of treatment, the patients will be followed-up for another 2 weeks. In case no full resolution of adverse events occurred at the 2 week follow-up visit, a follow-up call will be performed after another 2 weeks. Treatment responses will be photo documented

Treatment and study plan

PSO-CT02 device

Device

The PSO-CT02 device is worn on the affected skin area where it irradiates the target Eczema area for 30 minutes with blue light. A contralateral eczema area is left untreated and serves as control.

Primary outcomes

  1. Change From Baseline (Visit 2) of the Sum Score of Local Eczema Rating of the Target Area as Compared to the Control Area at End of Treatment

    Time frame: at week 4

    The investigator rated the key symptoms erythema, induration/papulation/edema, excoriation, lichenification and crusts on a score of 0-3 (none, mild, moderate, and severe) with half steps allowed. A total severity score was calculated as the sum of the single symptom ratings (range 0-15 whereas 0 (best) - 15 (worst)).

Secondary outcomes

  1. Change From Week 4 of the Sum Score of Local Eczema Rating as Compared to the Control Area at End of Follow-up

    Time frame: week 6

    The investigator rated the key symptoms erythema, induration/papulation/edema, excoriation, lichenification and crusts on a score of 0-3 (none, mild, moderate, and severe) with half steps allowed. A total severity score was calculated as the sum of the single symptom ratings (range 0-15 whereas 0 (best) - 15 (worst)).

  2. Change From Baseline of Inflammation (Erythema) Evaluated by Mexameter of the Target Area as Compared to the Control Area

    Time frame: week 4, 6

    Higher values describe higher erythema levels.

  3. Change From Week 4 (End of Treatment) of Inflammation (Erythema) Evaluated by Mexameter of the Target Area as Compared to the Control Area at End of Follow-up

    Time frame: week 6

    Higher values describe a higher level of erythema.

  4. Change From Baseline of Patient Rating of Itching of the Target Area as Compared to the Control Area

    Time frame: week 4, 6

    patients were asked to rate itching on a VAS scale (1 no itching; 100 worst imaginable itching)

  5. Change From Week 4 (End of Treatment) of Patient Rating of Itching of the Target Area as Compared to the Control Area at End of Follow-up

    Time frame: week 6

    patients were asked to rate itching on a VAS scale (1 no itching; 100 worst imaginable itching).

Other outcomes

  1. Hyperpigmentation - Evaluation by Mexameter

    Time frame: week 0, 2, 4, 6

    Higher values describe a higher level of pigmentation.

  2. Adverse Events (Serious and Non-serious)

    Time frame: week 0, 2, 4, 6

  3. Adverse Device Events (Serious and Non-serious)

    Time frame: over 6 weeks

  4. Device Deficiencies

    Time frame: over 6 weeks

    This measure describes device deficiencies in general leading to a non functional device. No specific characteristics were assessed.

  5. Recovery of Hyperpigmentation During Follow up Period (Compared to Last Treatment)

    Time frame: week 6

    Higher values describe a higher level of pigmentation.

  6. Number of Participants With Acceptance of Hyperpigmentation at Week 6

    Time frame: week 6

    Questionaire if hyperpigmentation was acceptable if reported. Outcome was number of patients answering "yes" or "no".
