Matching-Adjusted Indirect Comparison of the Long-Term Efficacy of Deucravacitinib Versus Adalimumab for Moderate to Severe Plaque Psoriasis
Bibliographic record
Abstract
Deucravacitinib, an oral tyrosine kinase 2 (TYK2) inhibitor, is approved in the United States to treat adults with moderate-to-severe plaque psoriasis (PsO). This study compared the long-term efficacies of deucravacitinib and adalimumab using results from long-term extension (LTE) trials. Open-label LTE trials were identified for an indirect treatment comparison (deucravacitinib: POETYK PSO-LTE [NCT04036435]; adalimumab: REVEAL extension [NCT00195676]). To ensure study design comparability, patients initially randomized to placebo and switched to deucravacitinib or adalimumab after week 16 were compared. The primary outcome was a ≥ 75% reduction in Psoriasis Area and Severity Index score (PASI 75) at week 112 postrandomization. Secondary outcomes were PASI 75 at week 52 and a ≥ 90% reduction in PASI score (PASI 90) at weeks 52 and 112. Missing PASI data were imputed. A matching-adjusted indirect comparison was conducted; individual patient-level data from POETYK PSO-LTE were reweighted to balance baseline characteristics with those from the REVEAL extension. Before reweighting, on average, patients in the POETYK PSO-LTE (N = 329) versus the REVEAL (N = 345) extension were older, had a lower body weight, received more prior systemic treatments, and had higher baseline PASI scores and week 16 placebo PASI 75 and PASI 90 response rates. Following reweighting, adjusted week 112 PASI 75 response rates were significantly higher for deucravacitinib versus adalimumab (67.2% vs. 54.0%; mean difference [95% CI], 13.2 [4.0–22.5] percentage points). Deucravacitinib had a numerically higher adjusted week 112 PASI 90 response rate (41.3% vs. 34.0%; mean difference [95% CI], 7.3 [− 2.0 to 16.7] percentage points). The treatments had similar week 52 adjusted PASI 75 and PASI 90 response rates. In this interim analysis, adults with moderate to severe PsO had higher long-term response rates at 2 years when treated with deucravacitinib versus adalimumab. Deucravacitinib response rates remained stable whereas adalimumab response rates declined in year 2. Plaque psoriasis is an inflammatory disease that causes red, itchy, dry patches (called plaques) on the skin. The disease cannot be cured, but the symptoms can be treated. Deucravacitinib and adalimumab are two treatments approved for use in adults with moderate to severe plaque psoriasis; deucravacitinib is an oral medication and adalimumab is injected with a needle under the skin. Each treatment has proven its efficacy compared with placebo (a pill or injection with no active effect) in separate clinical trials, but because no two clinical trials are exactly alike, the results cannot be accurately compared. Matching-adjusted indirect comparison is a method used to compare the results of one clinical trial with those of another when a direct comparison is not possible; characteristics from the patients in one trial are made to match the patient population in the other trial, and the adjusted results are compared. We performed a matching-adjusted indirect comparison of an open-label extension trial of deucravacitinib with an open-label extension trial of adalimumab to study the long-term efficacy of each treatment. At 1 year of treatment, we observed that similar proportions of patients receiving each treatment achieved a 75% or 90% improvement from their baseline Psoriasis Area and Severity Index score—called PASI 75 or PASI 90, respectively. At 2 years of treatment, similar proportions achieved PASI 90, but the proportion of patients receiving deucravacitinib who achieved PASI 75 was greater than that for patients receiving adalimumab.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
