TOPLINE:
study.
METHODOLOGY:
- The pragmatic, investigator-initiated, open-label, noninferiority, randomized trial compared the effectiveness of 12 weeks of treatment with narrow-band ultraviolet B phototherapy administered at home (n = 393) vs at the doctor’s office (n = 390).
- Overall, 783 patients with plaque or guttate psoriasis (mean age, 48 years; 48% women) were enrolled at 42 academic and private clinical dermatology practices in the United States from March 1, 2019, to December 4, 2023, and were followed up through June 2024. At baseline, the mean Physician Global Assessment (PGA) and the mean Dermatology Life Quality Index (DLQI) scores were 2.7 and 12.2, respectively.
- The two co-primary endpoints were a PGA score ≤ 1 indicating clear or almost clear skin and a DLQI score ≤ 5.
TAKEAWAY:
- At 12 weeks, a PGA score ≤ 1 was achieved in 32.8% of patients using home-based phototherapy and in 25.6% of those who received office-based phototherapy (P < .001).
- At 12 weeks, a DLQI score ≤ 5 was achieved in 52.4% and 33.6% of home- and office-treated patients, respectively (P < .001).
- Similar benefits were seen across all Fitzpatrick skin types.
- A higher percentage of patients were adherent to home-based (51.4%) vs office-based (15.9%) phototherapy (P < .001).
IN PRACTICE:
“These data support the use of home phototherapy as a first-line treatment option for psoriasis,” and “efforts are needed to make home and office phototherapy more available to patients,” said the study’s lead author.
SOURCE:
Joel M. Gelfand, MD, director of the Psoriasis and Phototherapy Treatment Center at the University of Pennsylvania, Philadelphia, presented the findings at the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis meeting during the annual meeting of the European Academy of Dermatology and Venereology, with simultaneous publication in JAMA Dermatology.
LIMITATIONS:
This was an open-label trial and because of its pragmatic design, outcome data were missing. The cost of the home-based phototherapy equipment used in the study was $6040.88, which was mostly covered by Medicare, but direct costs to patients may have varied depending on their insurance plan.
DISCLOSURES:
The Patient-Centered Outcomes Research Institute funded the study. Daavlin provided and shipped machines for home-based phototherapy to patients at no cost. Dr. Gelfand disclosed serving as a consultant for AbbVie, Artax, Bristol-Myers Squibb, Boehringer Ingelheim, Celldex, and other companies. The full list of author disclosures can be found in the published study.
