Brief Summary:
To compare the effectiveness, safety (tolerability), and duration of treatment response at 12 weeks of home versus office-based narrowband ultraviolet B phototherapy for the treatment of psoriasis

Condition or disease Intervention/treatment Phase
Psoriasis Psoriatic Plaque Device: Daavlin 7 series 3 panel narrow band phototherapy home units Device: narrow band phototherapy clinic units Not Applicable

Detailed Description:
The primary objective of this study is to compare the effectiveness, safety (tolerability), and duration of treatment response at 12 weeks of home versus office-based narrowband ultraviolet B phototherapy for the treatment of psoriasis. Physician Global Assessment (PGA) and Dermatology Life Quality Index (DLQI) will be used to assess effectiveness, safety (tolerability), and duration of treatment response. This is a three year pragmatic, randomized, active comparator effectiveness study.

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

Arm Intervention/treatment
Office Based Phototherapy
Patients randomized to this arm will receive narrow band phototherapy in a clinical setting via narrow band phototherapy clinic units.
 Device: narrow band phototherapy clinic units
Office based narrow band phototherapy unit (units typically have at least 24 bulbs in a surround structure
Active Comparator: Home Based Phototherapy
Patients randomized to this arm will receive narrow band phototherapy in a home setting via Daavlin 7 series 3 panel narrow band phototherapy home units.
 Device: Daavlin 7 series 3 panel narrow band phototherapy home units
Daavlin 7 series 3 panel narrow band phototherapy home units (with 8-12 bulbs and a smaller, flat surface with door, measuring 21" wide, 74.5" tall, and 23.5"). This unit is a class II device with a FDA 510K indication for psoriasis, vitiligo and atopic dermatitis/eczema. The unit will have a dosimetry controller, a UV sensor built in that measures the intensity of the light. This sensor will adjust the treatment time to compensate for any variation in output due to aging of the lamps or other factors


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. Treatment Response [ Time Frame: 12 weeks after randomization or earlier at discontinuation of phototherapy ]
    measured by Physician Global Assessment (PGA) score of clear/almost clear

  2. Impact of dermatological disease on quality of life [ Time Frame: 12 weeks after randomization ]
    Dermatology Life Quality Index (DLQI) score of ≤5 which corresponds to no to small impact of dermatologic disease on quality of life. DLQI is a 10 item survey that asks patients questions about their health related quality of life on a 0-3 scale. The DLQI is calculated by summing the score of each question resulting in a maximum of 30 and a minimum of 0. The higher the score, the more quality of life is impaired


Secondary Outcome Measures :
  1. Body Surface Area multiplied by Physician Global Assessment [ Time Frame: 12 weeks after randomization or earlier at discontinuation of phototherapy ]
    Physician Global Assessment multiplied by Body Surface Area (BSA). BSA is a measure that asks the physician or his or her designee to assess the body surface area affected by psoriasis using the handprint method in which the palm of the entire hand approximates 1% of the body surface area. To do this, the patient's handprint, including the entire area of the palm and all 5 digits with the fingers close together but not overlapping, is used as a guide to estimate 1% of the BSA

  2. Concomitant topical psoriasis treatment [ Time Frame: 24 weeks after randomization ]
    Patient reported topical psoriasis treatment

  3. Patient reported time associated with travel for phototherapy treatments [ Time Frame: 12 weeks after randomization or earlier at discontinuation of phototherapy ]
    patient reported survey

  4. Patient reported costs associated with travel for phototherapy treatments [ Time Frame: 12 weeks after randomization or earlier at discontinuation of phototherapy ]
    patient reported survey

  5. Patient reported time spent on phototherapy [ Time Frame: 12 weeks after randomization or earlier at discontinuation of phototherapy ]
    patient reported survey

  6. Phototherapy Dosing [ Time Frame: 12 weeks after randomization or earlier at discontinuation of phototherapy ]
    patient or site reported phototherapy dosing

  7. Duration of treatment response during observation period [ Time Frame: 24 weeks after randomization ]
    patient reported response to treatment
