Dupilumab and lebrikizumab have demonstrated efficacy in atopic dermatitis (AD) clinical trials; however, no direct comparisons exist. Efficacy outcome achievement (dupilumab and lebrikizumab with topical corticosteroids TCS) at 16 weeks and efficacy outcomes maintenance (dupilumab and lebrikizumab monotherapy without TCS) at 52 weeks were assessed using a placebo-adjusted Bucher indirect treatment comparison (ITC). Week 16 data were sourced from LIBERTY AD CHRONOS (dupilumab, n = 106; placebo, n = 315) and ADhere (lebrikizumab, n = 145; placebo, n = 66) trials. Week 52 data were sourced from SOLO-CONTINUE (dupilumab, n = 80; placebo, n = 39) and ADvocate 1 and 2 (lebrikizumab, n = 231; placebo, n = 60) trials, including patients who had achieved ≥ 75% improvement from baseline in Eczema Area and Severity Index (EASI)-75 or Investigator’s Global Assessment (IGA) score 0/1 (clear/almost clear) at week 16. Results are presented as odds ratios (ORs) with 95% confidence intervals (CIs). At week 16, patients receiving dupilumab every 2 weeks (q2w) + TCS had a significantly higher likelihood of achieving EASI-75 (OR 2.4; 95% CI 1.1–5.1) and a ≥ 4-point improvement in Peak Pruritus Numeric Rating Scale (PP-NRS; OR 2.7; 95% CI 1.2–6.0) versus those receiving lebrikizumab q2w + TCS. ORs for other endpoints (IGA-0/1 and ≥ 4-point improvement in Dermatology Life Quality Index) numerically favored dupilumab. At week 52, dupilumab q2w maintained a significantly higher OR for EASI-75 (OR 3.5; 95% CI 1.2–10.5) versus lebrikizumab every 4 weeks. ORs for EASI-90 (OR 3.3; 95% CI 1.0–11.3), IGA 0/1 (OR 3.3; 95% CI 0.7–15.1), and PP-NRS (OR 8.8; 95% CI 0.9–84.8) numerically favored dupilumab. Placebo-adjusted Bucher ITC analyses showed that the likelihood of achieving efficacy outcomes at 16 weeks and maintaining efficacy outcomes at 52 weeks was higher for dupilumab versus lebrikizumab recipients. Dupilumab and lebrikizumab are two drugs used to treat patients with moderate-to-severe atopic dermatitis (AD), a long-lasting condition that makes the skin dry, red, and itchy, affecting patients' everyday life. Both drugs work by blocking proteins that cause inflammation in the body, but differently: dupilumab blocks two proteins (interleukin-4 and interleukin-13) by targeting their receptor, while lebrikizumab blocks one protein (interleukin-13) directly. Several studies compared each drug with a placebo (inactive drug) with/without prescription skin creams (topical corticosteroids), but no studies have compared them with each other. We wanted to understand which drug might be more effective in treating AD, both short term and long term. We compared data from studies where each drug was tested against a placebo group, allowing us to indirectly compare the two drugs using a scientific method: "placebo-adjusted indirect treatment comparison". Two 16-week studies were used to understand the short-term effects when patients used dupilumab or lebrikizumab with prescription skin creams. For long-term effects, we used data from studies that included patients who got better at week 16 with either dupilumab or lebrikizumab, continued treatment up to week 52, and did not use prescription skin creams. Our results showed that in the short-term studies, patients treated with dupilumab had a better chance of improving how itchy their skin felt, the number of skin sores, and overall well-being, compared with those treated with lebrikizumab. In addition, patients who got better with dupilumab were more likely to maintain these improvements over 1 year compared with patients treated with lebrikizumab.
