Plaque Psoriasis Remission: What Does It Mean?
- A consensus definition for on-treatment remission in plaque psoriasis has been established by the National Psoriasis Foundation (NPF).
- The goal, according to the authors, was to create a definition of on-treatment remission for research and clinical use.
- Plaque psoriasis remission means the skin clears, and symptoms like scaling and itching disappear.
The National Psoriasis Foundation has established a definitive standard for “on-treatment remission” in plaque psoriasis, a crucial step for better patient care. Experts now agree this remission means either 0% body surface area involvement or an Investigator Global Assessment (IGA) score of 0,maintained for at least six months while undergoing treatment. This consensus, published in JAMA Dermatology, aids research adn clinical decision-making, setting clear expectations for patients. Without it, definitions vary. the NPF’s rigorous Delphi process, involving diverse stakeholders, shaped this vital benchmark. This new standard for plaque psoriasis remission provides clarity for treatment and assessment. News Directory 3 is committed to providing vital health data.

National Psoriasis Foundation Defines Plaque psoriasis Remission
Updated June 18, 2025
A consensus definition for on-treatment remission in plaque psoriasis has been established by the National Psoriasis Foundation (NPF). This aims to standardize expectations and improve disease management. Experts agreed that remission is maintaining either 0% body surface area (BSA) involvement or an Investigator Global Assessment (IGA) score of 0 for at least six months while on treatment.
The findings appeared in JAMA Dermatology. The goal, according to the authors, was to create a definition of on-treatment remission for research and clinical use. This will help evaluate patient responses when comparing therapies, existing and future. The definition requires maintaining a specific response level for a minimum time.
Plaque psoriasis remission means the skin clears, and symptoms like scaling and itching disappear. Without a standard definition, presentation and duration vary by individual, psoriasis type, and skin tone. Symptoms can appear differently in people of color, complicating assessment.Remission can last from one month to over a year, highlighting the need for a consistent definition to guide treatment and patient expectations.
The NPF’s Remission Workgroup used a Delphi process involving dermatologists, rheumatologists, researchers, patients, payers, and industry. The process included a literature review and pre-Delphi interviews to shape formal questions. Participants included those with mild (54%) and moderate to severe (46%) plaque psoriasis; 38% also had psoriatic arthritis. The group was 54% female, including African american (15%), Asian (23%), White (62%), and Hispanic or Latino (31%) individuals. Thirty-eight additional stakeholders offered perspectives via surveys.
A Delphi exercise with psoriasis specialists refined the criteria. this included 41 physicians, mainly dermatologists (81%), plus rheumatologists (17%) and a cardiologist.
Patients wanted complete absence of visible signs during therapy. Payers valued a standard definition for long-term coverage decisions. Clinicians agreed on defining on-treatment remission as maintaining 0% BSA involvement or an IGA score of 0 for at least six months on therapy. This offers a clear, achievable benchmark for care and research.
“Through a Delphi consensus process, on-treatment remission for plaque psoriasis was defined as patients maintaining a BSA involvement of 0% or IGA of 0 for at least 6 months while on treatment. This clear and standardized benchmark is applicable to both research and practice settings.”
What’s next
The new definition of psoriasis remission is expected to be used in future research and clinical settings to better evaluate treatment options and patient outcomes.
