Brief Summary:
This is a single centre randomised, placebo-controlled phase 2 study in which 96 children age 4 to 16 years with moderate to severe, longstanding allergic eczema will be enrolled.

Condition or disease Intervention/treatment Phase
Atopic Dermatitis Eczema Device: Nocturnal Temperature controlled Laminar Airflow (TLA) Treatment Device: Placebo TLA Device Not Applicable

Detailed Description:

Following a 4 to 6 week period on standardised treatment (run-in period, to ensure everyone starts with the same treatment approach), participants will be randomised to an active or dummy temperature-controlled laminar airflow (TLA) device, which has been shown to markedly reduce exposure to particles which can cause allergic reactions when being inhaled (inhaled allergens) and other particles which are in the air the investigators breathe in. This has been shown to be an effective treatment of atopic asthma.

The participants will undergo a 12-week treatment period. The device will then be removed and a final follow-up visit occurs at 16 weeks. The total study duration, including the run-in period is up to 22 weeks.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change of eczema severity (Eczema Area Severity Index = EASI Score, total) at week 12 compared to baseline [ Time Frame: 12 weeks ]
    Change of eczema severity (EASI Score) at week 12 compared to baseline; higher score = higher severity. range 0-72 (0=no eczema, 72 highest severity)


Secondary Outcome Measures :
  1. (Eczema Area Severity Index = EASI): EASI 50, EASI 75 [ Time Frame: 12 weeks ]
    Proportion of participants achieving at least a 50% (EASI 50) or 75% (EASI 75) reduction of eczema severity. EASI range 0-72 (0=no eczema, 72 highest severity)

  2. Change in SCORing Atopic Dermatitis = SCORAD Index [ Time Frame: 12 weeks ]
    Change in total SCORAD Index at week 12 compared to baseline; higher score = higher severity; range 0-103 (0=no eczema, 103 highest severity)

  3. Proportion of subjects achieving Investigator Global Assessment (IGA) of 0 or 1 [ Time Frame: 12 weeks ]
    Proportion of subjects achieving Investigator Global Assessment (IGA) of 0 or 1; maximum score is 5 = most severe

  4. Change in health related quality of life [QoL] from baseline for participants: CDQLI [ Time Frame: 20-22 weeks (baseline 4-6 weeks, intervention 12 weeks, 4 weeks after intervention) ]
    Change in health related quality of life during run-in period, 12 week treatment period and 4 weeks after treatment end using Children's Dermatitis Quality of Life Index (CDQLI). Range 0-30 (0=no QoL impairment, 30 severe QoL impairment)

  5. Improvement of itch; Visual Analogue Score (VAS), from baseline [ Time Frame: 20-22 weeks (baseline 4-6 weeks, intervention 12 weeks, 4 weeks after intervention) ]
    Change of itch intensity during during run-in period, 12 week treatment period; and 4 weeks after treatment end; Visual Analogue Score (VAS) range 0-100; higher score = higher severity

  6. Improvement of sleep; Visual Analogue Score (VAS), from baseline [ Time Frame: 20-22 weeks (baseline 4-6 weeks, intervention 12 weeks, 4 weeks after intervention) ]
    Change of sleep disturbance during run-in period, 12 week treatment period and 4 weeks after treatment end; Visual Analogue Score (VAS) range 0-100; higher score = higher severity

  7. Change in adverse impact on participants' families from baseline [ Time Frame: 20-22 weeks (baseline 4-6 weeks, intervention 12 weeks, 4 weeks after intervention) ]
    Change in adverse impact of participants' eczema on families,during run-in period, 12 week treatment period and 4 weeks after treatment end using Dermatitis Family Impact Questionnaire (DFI); higher score = worse impact. Range 0-30 (0=no impact, 30 severe adverse impact)

  8. Change of patient reported eczema activity from baseline [ Time Frame: 20-22 weeks (baseline 4-6 weeks, intervention 12 weeks, 4 weeks after intervention) ]
    Change of patient reported eczema activity during run-in period, 12 week treatment period and 4 weeks after treatment end, using Patient Oriented Eczema Measure (POEM) tool; total score reported, higher score = higher severity; Range 0-28 (0=no impairment, 28 severe reported eczema symptoms)

  9. Change in medication requirements (topical immunomodulators) from baseline [ Time Frame: 20-22 weeks (baseline 4-6 weeks, intervention 12 weeks, 4 weeks after intervention) ]
    Change in medication requirements during run-in period, 12 week treatment period and 4 weeks after treatment end (topical immunomodulators, topical steroids, topical calcineurin inhibitors) from baseline

  10. Change in sleep quality from baseline: actigraphy [ Time Frame: 4-6 weeks ]
    Change in sleep quality, measured by actigraphy before and in first month after intervention start (total movement activity reported, higher scores = worse sleep disturbance); this is not a limited scale but simply counts the number of times an individual moves.
