3 Streamlined severity based treatment model Practical suggestions for treatment plans MILD DISEASE Basic Management Skin care Antiseptic measures Trigger avoidance Algorithm for Care of Atopic Dermatitis MODERATE TO SEVERE DISEASE Maintenance (Proactive) TCI (pimecrolimus/tacrolimus) TCI 2 3 x weekly OR if patient is non responsive 1 2 x daily Maintenance (Proactive) TC Medium potency TC (Class III IV) 1 2 x weekly (except for face/eyes) AND/OR Low potency TC (Class V VII) 1 2 x daily (including face/eyes) Acute Treatment Topical antiinflammatory applied to inflamed skin Low potency TC (Class VII) bid for up to 3 days beyond clearance Modified from Eichenfield LF et al. Pediatrics 2015; 136(3): For relapsing course (frequent/persistent flares despite treatment) TC at first signs/symptom or maintenance Acute Treatment Topical anti inflammatory applied to inflamed skin Medium potency TC (Class III IV) bid for up to 3 days beyond clearance Flare not resolved in 7 days Consider nonadherence, infection, misdiagnosis Step wise Treatment Algorithm Recalcitrant moderate to severe AD Systemic immunosuppressive/ immunomodulatory (e.g. CSA, AZA, MTX, MMF, Dupilumab**) or UV therapy Moderate AD Activity of disease Mid high potency TCS &/or TCI*, Proactive TCS or TCI, Wet wraps Mild AD Low mid potency TCS and/or TCI * or Crisaborole * Basic treatment: Skin hydration, moisturizers, bleach baths, avoidance of irritants and triggers Adapted from Akdis CA et al.

5 Secondary End Points Simpson EL et al. N Engl J Med 2016;375: Simpson EL et al. N Engl J Med 2016; 375: Conclusions from Phase III Dupilumab Trials Both dose regimens of dupilumab showed clinically meaningful improvement and statistical significance vs. placebo in: AD signs & symptoms (including itch/pruritus and sleep) Health related quality of life Symptoms of anxiety/depression Most AEs were mild or moderate Injection site reactions and conjunctivitis were more frequent with dupilumab Fewer skin infections in dupilumab group Simpson EL et al. N Engl J Med 2016; 375: Considerations for Prescribing Dupilumab Hypersensitivity reactions - Urticaria - Serum sickness or serum sickness like reactions reported 2/1472 subjects Patients should not adjust/stop their asthma treatments without consultation with their physicians. Patients with known helminth infections were excluded from participation in clinical studies. Avoid live viral vaccines. Ref: Package Insert 5

6 Prescribing Dupilumab Conjunctivitis should be promptly treated Can be used with topical steroids Topical calcineurin inhibitors may be used, but reserved for problem areas only, such as the face, neck, intertriginous and genital areas. Missed doses - within 7 days, administer & resume the patient s original schedule. - > 7 days, skip dose and give next dose on the original schedule.

11 Antihistamines.evidence based review of 16 controlled studies revealed little objective evidence demonstrating the relief of pruritus when sedating or non sedating antihistamines were used in the treatment of AD. Reduction of skin inflammation with will often reduce pruritus. Schneider L, Tilles S, Lio P, Boguniewicz M, Beck L, et al.

Journal of Allergy and Clinical Immunology , DOI: ( /j.jaci ) Copyright 2017 American Academy of Allergy, Asthma & Immunology The clinician should recognize that AD has a significant impact on quality of life and patients have an increased risk for psychological distress. Schneider L, Tilles S, Lio P, Boguniewicz M, Beck L, et al. J Allergy Clin Immunol Feb; 131:

12 The clinician should assess for sleep disturbances. Optimize sleep hygiene Treat AD inflammation aggressively to improve sleep and itching Refer to psychologist or sleep specialist if needed Schneider L, Tilles S, Lio P, Boguniewicz M, Beck L, et al. J Allergy Clin Immunol Feb; 131: Improve Adherence Educate patients about AD & demonstrate skin care Give patients a written plan and assess understanding of skin care plan Develop a skin care schedule Assess concerns about medications Assess barriers What are the hardest parts for you/your child to follow? What parts do you skip/miss the most? Chou J et al. Allergy and Asthma Proceedings. 2011;32(5): English.pdf 12
